Description

TECHNICAL FIELD

[0001] The utility model belongs to key mould technical field, concretely relates to a novel plastic key mould. BACKGROUND

[0002] Plastic keys are widely used in electronic devices, household appliances, automobile control panels and other fields, and their manufacturing process mainly relies on injection molding technology. During injection molding, the design and performance of the mold directly determine the dimensional accuracy, surface quality and production efficiency of the plastic key. At present, the technology of plastic key mold has been relatively mature, but there are still some problems to be solved.

[0003] The existing plastic key mold technology mainly includes the following aspects:

[0004] Mold material: usually made of high hardness and high wear resistance steel (such as P20, 718, etc.) to improve the service life of the mold.

[0005] Mold structure: including cavity, core, ejection mechanism, cooling system and other parts, the structure is complex, and the design precision is high.

[0006] Cooling system: reduce the temperature of the mold through the built-in cooling water channel, shorten the molding cycle and improve the production efficiency.

[0007] Surface treatment: polishing, electroplating and other treatments are carried out on the mold cavity to improve the surface finish of the plastic key.

[0008] However, the mold will generate a lot of heat during work, especially in high-intensity continuous operation, the rise of mold temperature will directly affect the quality of products and production efficiency. Therefore, how to effectively solve the problem of mold heat dissipation becomes an important issue in the current technical field.

[0009] At present, the common mold heat dissipation technology mainly includes the following:

[0010] Natural heat dissipation: through the heat conduction performance of the mold itself material to dissipate heat to the air. However, the efficiency of natural heat dissipation is low, which cannot meet the demand of high-intensity operation.

[0011] Air cooling: use fan to accelerate air flow to take away the heat on the surface of the mold. Although the efficiency of air cooling is higher than that of natural heat dissipation, its heat dissipation effect is still limited in high temperature environment.

[0012] Water cooling: through the circulation of cooling liquid to absorb the heat inside the mold, and then through the heat exchange with air through the radiator. The efficiency of water cooling is higher, but in practical application, the circulation speed of cooling liquid and the heat exchange efficiency of radiator still need to be improved.

[0013] Based on the above, the present scheme provides a new plastic key mold with the advantages of fast cooling speed and high heat dissipation efficiency. Utility model content
