Synchronous core-pulling mechanism on the inner and outer sides of the injection mold for automobile wheel covers

Abstract

The invention discloses an inside and outside synchronous core pulling mechanism of a vehicle wheel cover injection mould, which comprises an outside core pulling slide block (1), an oblique guide block (12), an inside core pulling slide block (2), an oblique wedge slide block (21), an oil cylinder (22) and a connecting rod (23). The outside core pulling slide block is glidingly arranged at the core pulling forming place on the outer side of a dynamic model core; the oblique guide block is fixedly arranged at a fixed model cavity; an opening mould is used for driving the outside core pulling slide block to perform core pulling movement outwards; a mechanism consisting of the oil cylinder, the connecting rod and the oblique wedge slide block is arranged in the dynamic model core and a dynamic template at the core pulling forming place of the inside core pulling slide block; and the oil cylinder is used for driving the inside core pulling slide block to perform core pulling movement inwards. Due to the adoption of the technical scheme that core pulling is performed on the inner side and the outer side of a product at the same time, the problems and disadvantages of complex mechanism, big volume and high cost of the prior art are solved and overcome, and the aims of simplifying the mechanism, reducing the volume and reducing the cost of the vehicle wheel cover injection mould arefulfilled.

Description

technical field [0001] The invention relates to a core-pulling and demoulding mechanism of an injection mold, in particular to an automobile wheel cover which is applied to an injection mold of an automobile wheel cover and is used for simultaneously performing core-pulling and demoulding on the inner and outer sides of an injection-molded automobile wheel cover product The inner and outer sides of the injection mold are synchronized with the core-pulling mechanism. Background technique [0002] Injection molding of automotive wheel cover products requires demoulding and core pulling on both sides of the product. The existing technology uses an asynchronous method of first outside and then inside to pull the core on both sides of the product, that is, use the mold to open the mold and move the mold back. , the movable and fixed molds are separated, and the core-pulling slider embedded in the outer side of the product is driven by the inclined guide column to complete the ext...

[0002] Injection molding of automotive wheel cover products requires demoulding and core pulling on both sides of the product. The existing technology uses an asynchronous method of first outside and then inside to pull the core on both sides of the product, that is, use the mold to open the mold and move the mold back. , the movable and fixed molds are separated, and the core-pulling slider embedded in the outer side of the product is driven by the inclined guide column to complete the external lateral core-pulling. The internal lateral core pulling is completed, and finally the ejector rod is pushed by the top plate to push the product out of the moving model core to realize the demoulding of the product; the above asynchronous method also needs to coordinate the synchronous or asynchronous ejection action between the inclined top core pulling mechanism and the ejector rod, so that The mechanism is complicated and the volume is large, which leads to the high cost of the mold itself. In addition, the injection molding production must occupy an injection molding machine with a large work opening, resulting in a large horse-drawn cart and an increase in production costs. Therefore, the existing technology has a mechanism Problems and deficiencies of complexity, large size and high cost
