Test plate mold pressing mold

Abstract

The invention provides a test plate mold pressing mold which comprises an upper mold, a lower mold, an upper electric heating plate, a lower electric heating plate and a positioning component. The upper mold and the lower mold form a closed cavity, glue injection ports are formed in two side surfaces of the lower mold along the length direction of the lower mold and communicated with the closed cavity, the upper mold is fixed onto the upper electric heating plate of a press through a pressing plate, the lower mold is arranged on the lower electric heating plate of the press, and the positioning component is of an L-shaped positioning structure. The test plate mold pressing mold is simple in structure and convenient to operate and solves the problems that the mold is deformed, complex in structure, heavy and inconvenient to operate and clean and leaks air, and product accuracy cannot be ensured. Time and labor are saved, and batch production of test plates is achieved on the premise of simplifying process operation.

Description

technical field [0001] The invention relates to a test board molding die. Background technique [0002] RTM is the abbreviation of Resin Transfer Moulding. RTM process is generally used for the production of composite parts with complex profiles and high requirements for all surface quality. It is a low-cost liquid molding technology that does not use prepreg. Five processes such as mould, etc. complete the production of parts. Because the RTM process has the characteristics of high production efficiency, high manufacturing precision, good surface quality, and the ability to directly form complex and shaped products, it has been more and more widely used in aerospace, rail transportation and other fields. [0003] Since the RTM test board has a variety of thicknesses, in the test board molding die, the thickness of the mold can be quickly changed, thereby changing the thickness of the product, and achieving the purpose of mass production and high-efficiency production of t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a test plate molding die to solve the problem in the prior art that the upper platen of the press cannot be completely in contact with the upper die due to the glue injection port being arranged on the lower die of the die, resulting in deformation of the die and leakage of the die. Gas, product accuracy cannot be guaranteed, the mold structure using oil heating method is more complicated, the weight is heavy, the oil circuit design is cumbersome, and auxiliary equipment such as mold temperature controller is needed, and the safety is poor.
