Suspension type flash-free foaming mold

Abstract

The invention provides a suspension type flash-free foaming mold. The suspension type flash-free foaming mold comprises an injection molding assembly and a suspension adjusting assembly. The injectionmolding assembly comprises a front mold plate and a rear mold plate. The front mold plate is connected with the rear mold plate. The suspension adjusting assembly comprises a floating plate and multiple buffer abutting parts. The buffer abutting parts are arranged on the floating plate. According to the suspension type flash-free foaming mold, through the arrangement of the floating plate and themultiple buffer abutting parts, in a mold opening state, the floating plate is separated from the rear mold plate through the elastic effect of the buffer abutting parts, the buffer abutting parts support overall gravity, when the mold is in a mold closing state, the front mold plate and the rear mold plate receive the effect of mold closing force, the gap becomes smaller, at the moment, the rearmold plate is continuously close to the front mold plate through elastic force of the buffer abutting parts, thus, the rear mold plate and the front mold plate are in a balanced state, and the flashdefect generated as the rear mold plate and the front mold plate are not balanced can be avoided.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a suspended foaming mold without flash. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. [0003] In the injection foaming process of the automobile steering wheel, due to the limitation of the precision of the mold base and the mold, the foamed automobile steering wheel has flash defects, so it is necessary to manually eliminate the flash of the automobile steering wheel. Material resources, and the quality of mol...

AI Technical Summary

Problems solved by technology

[0004] 1. Because the foaming raw material is PU, this material is liquid and has good fluidity, and it is easy to produce burrs, which requires high mold fit clearance;

[0005] 2. The clamping force of the foaming mold base is small, and the balance has errors. It is easy to tilt when closing the mold, and the foaming product will produce uneven flash;

[0006] 3. The curved shape of the parting surface of the product increases the difficulty of processing and assembly, and is prone to errors, resulting in the lack of accuracy of the mold mating surface and prone to flashing
