Description

Get rid of die-cut device of wheel hub dress trim cover mouth of a river material of moulding plastics

Technical Field

The utility model relates to a wheel hub dress trim cover production facility technical field, in particular to get rid of wheel hub dress trim cover die-cut device of mouth of a river material of moulding plastics.

Background

The hard plastic hub decorative cover is formed by injection molding. Injection molding is a processing method used for mass production of parts with complex shapes, and particularly relates to a method for obtaining a formed product by injecting a material melted by heating into a mold cavity and cooling and solidifying the material. The pouring system refers to a runner part before plastic melt enters a cavity from a nozzle of an injection machine, and comprises a main runner, a cold material cavity, a sub-runner, a pouring gate and the like. When the injection molding product has appearance requirements and glue can not be directly injected into the outer surface, the pouring gate is arranged on the ejector pin in a hidden pouring gate mode, so that the plastic directly flows to the product from the ejector pin, and the purpose of normal injection molding of the product is achieved.

Particularly, the hollow shell of the hub decorative cover is solved and controlled by adopting a mode of adding the connecting rib for preventing shrinkage deformation after demolding, so that the connecting rib needs to be removed in the production process.

The prior art mainly adopts manpower and die-cut joint bar of getting rid of the injection molding. For example, patent CN211492682U, "a device for cutting off injection-molded shell remnants". In this patent, the during operation adopts the cylinder as the power supply, and die-cut blade is force applying device, and disposable both sides are die-cut simultaneously and are got rid of the splice bar on the casing of moulding plastics. In this patent, the clout die-cut of a slice dress trim cover can only be accomplished once, only after accomplishing the clout die-cut of a slice dress trim cover, just can place a new slice dress trim cover and carry out the clout die-cut in the device. Workers can only wait for punching in a dry process, and the time utilization rate is low.
