Description

TECHNICAL FIELD

[0002] The mold is called the mother of industry, and a more ingenious mold structure design will greatly improve the structure, quality and production efficiency of the product, so the requirement for mold design workers is also higher. The development and design of the double-material mold is to meet the requirements of customers for different materials, hardness and colors at different positions of the same product, and it can realize different materials, colors and hardness at different positions in the same mold according to requirements.

[0003] In the use process of the existing double-material sliding block mold, it is difficult to apply micro-vibration to the double-material joint surface and match the material molten state, which reduces the molecular diffusion, and it is also difficult to improve the melt wetting property of the double-material interface, so the practicality is relatively single. In the use process of the prior art, it is difficult to compensate for the gap between the sliding block and the mold, which reduces the mold closing accuracy, thereby preventing the formation of melt leakage and air gap;

[0004] In addition, in the use process of the existing double-material sliding block mold, it is difficult to configure a temperature control area for each material injection, thereby it is difficult to solve the thermodynamic contradiction of multi-material co-injection, and the product defect rate is increased. The melt is prone to stratification due to uneven flow rate during flow, and the prior art is difficult to reduce the local difference of the melt temperature and viscosity, thereby causing the melt state at the gate to be relatively uneven, increasing the possibility of local clogging or covering of the detection part.

[0005] Finally, in the use process of the existing double-material sliding block mold, it is difficult to perform elastic detection on the product completed by one-time injection molding, thereby it is difficult to provide a basic performance anchor point for two-layer injection molding, which increases the product defect rate and shortens the service life of the product.
