Abstract

The invention discloses a pneumatic pressure injection forming device. The pneumatic pressure injection forming device comprises a driving part, a forming part, a structure supporting part and a rapid locking part. An air cylinder is driven by adjusting the turning direction of a reversing valve, and a piston of the forming part is moved downwards and presses paraffin into a mold cavity rapidly. A base and a top plate in the structure supporting part are used for connecting the fixing forming part, the driving part and the rapid locking part. The paraffin can realize pressure injection forming of a paraffin mold at the speed of 20 ml / s through a pneumatic mode, the surface of the paraffin mold obtained through pressure injection is good in quality, and a formed part is uniform in density. The time for dismounting and mounting the mold is shortened through the arrangement of the rapid locking device, so that the processing efficiency is greatly improved. The pneumatic pressure injection forming device reduces processing cost, relieves labor intensity, can realize small-batch production, has the characteristics of convenience and high efficiency, and can realize teaching demonstration in pressure injection forming and injection forming experiment processes.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing and the field of teaching, in particular to a pneumatic injection molding device. Background technique [0002] With the advent of the era of multi-variety and small batches, the structure of traditional die-casting devices is complex, and mold manufacturing consumes a lot of time, manpower and material resources, and the precision of finished products is low. In order to shorten the production cycle of parts faster and reduce costs, Through the design of the manufactured pneumatic injection molding device, products with relatively complex structures can be formed, and the quality of the parts is improved, labor and cost are reduced, and efficiency is improved, so that mold manufacturing can ensure that new products can be quickly occupied market. In addition, in the process of practical teaching, the development of a simple experimental device that is conducive to students' understand...
