Injection mold for automobile bonnets

Abstract

The invention discloses an injection mold for automobile bonnets. The injection mold comprises a lower die, an electric push rod, an upper die and a disc, wherein a push device is fixedly installed inthe bottom center of the lower die, a push hole is formed in the bottom of the side of the lower die, the electric push rod is fixed to the side of the lower die, a signal control switch is installedon the electric push rod, a connecting rod is perpendicularly connected to the edge of the electric push rod, an ejector pin is arranged on the connecting rod, the ejector pin is located in the pushhole, the upper die is located just above the lower die, a lifting rod is fixedly connected to the top center of the upper die, an injection hole is formed in the top edge of the upper die, a chute isreserved in the side of the injection hole, the disc is arranged in the chute, a sliding block is connected to the top of the disc, and the sliding block is located above the chute. According to theinjection mold for the automobile bonnets, the product ejection smoothness is increased, the product ejection deformation damage is reduced, and additionally, the product forming quality and speed areincreased.

Description

Technical field [0001] The invention relates to the technical field of injection moulds, in particular to an injection mould for automobile hoods. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of some complex-shaped parts. Specifically, it refers to the high-pressure injection of the plastic melted by heat into the mold cavity by the injection molding machine, and the molded product is obtained after cooling and solidification. [0003] However, when the existing automobile hood injection mold is used and operated, the hood is easily damaged when taken out, and the molding cooling effect of the mold is not good, and the amount and rate of raw material injection molding are not easy to control, resulting in poor product molding quality. In view of the above-mentioned problems, it is ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of automobile cover injection mold, to solve the above-mentioned background technology, propose that when the existing automobile cover injection mold is used and operated, the take-out of the vehicle cover is easy to be damaged, and the molding cooling effect of the mold is not good at the same time. Moreover, the amount and rate of raw material injection molding are not easy to control, which makes the quality of product molding poor.
