Several mold repair methods commonly used in molds

There are many methods of mold classification, which are often used in the past: classification according to the structural form of the mold, such as single-process mold, duplex die, etc.; Classified according to the use object, such as automobile panel mold, motor mold, etc.; Classified according to the nature of processed materials, such as molds for metal products, molds for non-metallic products, etc.; Classified according to mold manufacturing materials, such as cemented carbide molds, etc.; Classified according to the nature of the process, such as drawing die, powder metallurgy die, forging die, etc. Some of these classification methods cannot fully reflect the structure of various molds and the characteristics of the forming process, as well as their use functions.

To this end, a comprehensive classification method based on the process properties and objects of forming processing using dies is adopted, and the dies are divided into: stamping dies (stamping dies), plastic molding molds, die-casting molds, forging molds, metal molds for casting, powders, etc

Mold plays an extremely important role in modern industry, and its quality directly determines the quality of the product. Improving the service life and accuracy of the mold and shortening the manufacturing cycle of the mold are technical problems that many enterprises urgently need to solve, but failure forms such as collapse corners, deformation, wear, and even fracture often occur in the process of mold use. Therefore, the repair of the mold is also necessary.

There are many ways to repair molds, such as EDM process, argon arc welding repair, laser surfacing technology, and brush plating method.

TIG welding repair.

The arc that burns between the continuously fed wire and the workpiece is used as the heat source, and the gas shielded arc ejected from the torch nozzle is used for welding. At present, argon arc welding is a commonly used method and can be applied to most major metals, including carbon steel and alloy steel. Molten inert gas shielded welding is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys, due to the low quality, it is widely used in mold repair welding, but the welding heat affected area is large, the solder joint and other shortcomings, at present, in the precision mold repair has been gradually replaced by laser welding.

Brush plating repair.

Brush plating technology is the use of a special DC power supply equipment, the positive pole of the power supply is connected to the plating pen, as the anode during brush plating; The negative pole of the power supply is connected to the workpiece and is used as the cathode for brush plating. The plating pen usually uses a high-purity fine graphite block as the anode material, and the graphite block is wrapped with cotton and a wear-resistant polyester cotton sleeve. During operation, the power supply component is adjusted to the appropriate voltage, and the plating pen filled with plating solution moves back and forth on the surface of the repaired workpiece at a certain relative movement speed, and maintains a certain pressure until a uniform and ideal metal deposition layer is formed.

Due to the part where the plating pen is in contact with the surface of the repaired workpiece, the metal ions in the plating solution diffuse to the surface of the workpiece under the action of electric field force, and the electrons obtained on the surface are reduced to metal atoms, so that these metal atoms are deposited and crystallized to form a coating, that is, the required uniform deposition layer is obtained on the working surface of the cavity of the repaired plastic mold.

Laser hardfacing repair.

Laser welding is the use of a high-power coherent monochromatic photon stream focused by a laser beam as a heat source. This welding method usually has continuous power laser welding and pulsed power laser welding. The advantage of laser welding is that it does not need to be carried out in a vacuum, and the disadvantage is that the penetration is not as strong as that of electron beam welding.

Precise energy control can be carried out during laser welding, so that precision devices can be welded. It can be applied to many metals, especially the welding of some difficult-to-weld metals and dissimilar metals. At present, it has been widely used in the repair of molds.

Hello, I am glad to answer for you, the importance of mold making and repair is to ensure the accuracy and durability of the mold, so as to produce high-quality products. In the process of mold making and repair, the most important thing is the maintenance of the mold. This includes:

1.Regularly clean the surface and internal channels of the mold to prevent the mold from being contaminated with impurities and accumulating dust. 2.

Repair the wear and damage on the surface of the mold in time to prevent further expansion. 3.Lubricate the moving parts and friction surfaces of the mold regularly to ensure the smooth operation of the mold.

4.The mold is strictly tested and tested to ensure the dimensional accuracy and quality stability of the mold. 5.

According to the use and loss of the mold, repair and replace it in time. Maintenance is the most important part of the mold making and repair process, and only by doing a good job of maintenance can we ensure the normal operation and long-term stability of the mold. I hope Wang Bo can help you and wish you a happy life!

Dear, hello, I have kept you waiting, I am happy to answer for you, in mold making and repair, the most important thing is precision control. Making and repairing molds requires high-precision machining and processing capabilities to ensure that the quality and accuracy of the molds meet the requirements. In general, the machining and handling precision of molds is very high, even down to the sub-micron level.

Therefore, the process of making and repairing molds requires a high degree of technical requirements and expertise. In addition, the choice of materials is also very important in mold making and repair. Mold stools are usually made of high-strength alloy materials to ensure their durability and longevity.

When manufacturing and repairing molds, it is necessary to select appropriate materials to ensure that the strength, hardness, and toughness of the mold meet the requirements. Finally, it should be noted that mold making and repair require strict quality control and testing processes. During the fabrication and repair process, multiple inspections and tests are required to ensure that the quality and accuracy of the mold meet the requirements.

Only in this way can we ensure that the quality and performance of the mold meet the requirements and meet the needs of customers.

The basic concept of hardware mold repair is that the workers engaged in various kinds of labor in the production and work positions are cracked, and the business strategy, policy, objectives and on-site problems of the enterprise are revolved. The aim is to improve quality, reduce consumption, improve human quality and economic benefits. When repairing the mold due to faults, it is necessary to attach a material belt to facilitate the inquiry of the problem.

Open the mold, take care of the belt, check the condition of the mold, confirm the cause of the failure, find out the problem, and then clean the mold early before removing the mold. The purpose is to improve the quality and production efficiency of mold opening and repair, so that the order production can be carried out in an orderly manner to meet the production demand.
