Precision plastic mold

Abstract

The present invention discloses a precision plastic mold, which comprises a mold insert, wherein the mold insert is provided with a casting cavity, a casting core member is embedded in the casting cavity, the casting core member and the casting cavity form interference fit, the tolerance of the interference fit is 0.01 mm, and the casting core member comprises a casting channel and a casting port. According to the present invention, the precision plastic mold has the independent mold casting core member, the casting core member and the whole mold can be easily separated, and when the casting core member wears during the work process so as to affect the plastic molding, the casting core member can be easily replaced, such that the time and the labor are saved during the practical application, the material and the cost are saved, and the environmental protection advantage is provided; the cost of the mold using the guide system is slightly improved while the mold structure is easy to use, the molding production is achieved, and the product injection molding cost is reduced; and the stability and the safety of the mold after the use of the system are substantially improved, the molding precision of the produced plastic member is improved, the appearance is clean, the assembly coordination of the product is improved, and the rejection rate is substantially reduced.

[0003] Plastic molds for scientific and educational building blocks are prone to damage under recycling

Modern industrial production requires molds with high precision, long life, large output and fast production speed, which poses new challenges to the stability and durability of molds.

For molds made by traditional techniques, the mold base and core parts are completely integrated. Once damaged, production will be stopped for repair, delaying the construction period

In particular, the ejection system is a moving part. If the guide is not good, maintenance and replacement are often required, which not only affects the production schedule, but also increases maintenance costs.

Molds made by traditional techniques cannot meet the current needs of automated production. It is necessary to innovate the manufacturing process and structure of scientific and educational building block plastic molds to improve the efficiency of injection molding production, thereby increasing production capacity and saving costs.
