Injection mold of insert contactor of glass rubber channel of automobile

Abstract

The invention discloses an injection mold of an insert contactor of a glass rubber channel of an automobile. The injection mold comprises an upper movable mold (1), a lower fixed mold (2) and an inserting core (3), wherein the upper movable mold is provided with an upper moving cavity and a guide block; the lower fixed mold is provided with a base seat plate, a lower moving plate, an intermediate moving plate, an upper moving plate, a manual inserting core slide seat, a lower plate spring, an intermediate plate spring, an upper plate spring and an inserting core spring; the base seat plate is provided with a base cavity; the lower moving plate is provided with a lower cavity; the intermediate moving plate is provided with an intermediate cavity; the upper moving plate is provided with an upper cavity; the manual inserting core slide seat is positioned on the right side surface of the lower moving plate and can slide leftwards and rightwards; the inserting core is positioned on the upper surface of the manual inserting core slide seat; the lower moving plate is positioned on the upper surface of the base seat plate; the intermediate moving plate is positioned on the upper surface of the lower moving plate; the upper moving plate is positioned on the upper surface of the intermediate moving plate; the upper moving mold is positioned on the upper surface of the lower fixed mold. A technical scheme of connecting an insert A and an insert B through the insert contactor formed by injection molding is adopted, thus a glass rubber channel product can achieve the purposes of improving the shape, improving the strength, improving the production efficiency, and decreasing the production cost.

Description

technical field [0001] The invention relates to an insert injection mould, in particular to an insert corner injection mold for automobile woolen products used for insert injection molding of automobile woolen goods. Background technique [0002] refer to Figure 7 , Automobile woolen products, referred to as woolen products, are hollow tubular, bent, soft rubber and plastic parts with special-shaped cross-sections; because there are many undercuts on the outer wall of the woolen products, the inside of the lumen is also set. There are many ribs and flange steps, which makes it difficult to produce by one-time injection molding. For this reason, the existing technology adopts the method of dividing the woolen product into two parts A and B at the bending point, and then injects them respectively The semi-finished products of parts A and B are then connected by hot-melt welding to A and B into woolen products. Due to hot-melt welding, protruding fusion scars will be formed at...

Problems solved by technology

[0002] refer to Figure 7 , Automobile woolen products, referred to as woolen products, are hollow tubular, bent, soft rubber and plastic parts with special-shaped cross-sections; because there are many undercuts on the outer wall of the woolen products, the inside of the lumen is also set. There are many ribs and flange steps, which makes it difficult to produce by one-time injection molding. For this reason, the existing technology adopts the method of dividing the woolen product into two parts A and B at the bending point, and then injects them respectively The semi-finished products of parts A and B are then connected by hot-melt welding to A and B into woolen products. Due to hot-melt welding, protruding fusion scars will be formed at the fusion joints, and the microbubbles generated during fusion will cause melting. The connection strength at the junction decreases. Although the fusion scars can be removed by manual cutting with the help of cutting tools, the woolen products still have the disadvantages of poor appearance and low fusion strength, and the repair and cutting of fusion scars requires a lot of labor, high cost, and low efficiency. Therefore, the prior art has the problems and deficiencies of poor appearance, low strength, high cost, and low efficiency
