Injection molding processing method of elastomers and elastic processing system for injection molding of elastomers

Abstract

The invention provides an injection molding processing method of elastomers and simultaneously provides an elastic processing system facilitating the implementation of the processing method. According to the invention, a mold for molding an elastomer is moved between a first mold clamping mechanism and a second mold clamping mechanism under control, meanwhile, a maximal mold clamping force provided by the first mold clamping mechanism is set to be greater than the force provided by the second mold clamping mechanism. Thereby, injection of raw materials can be carried out smoothly, then, the mold is moved to the second mold clamping mechanism after injection of raw materials, the second mold clamping mechanism provides a relatively smaller mold clamping force for the mold, and the mold is used for molding the injected elastomer, and thus, energy consumption is reduced.

Description

technical field [0001] The invention relates to polymer processing technology, in particular to an injection molding processing method of elastic body and an elastic processing system for implementing the processing method. Background technique [0002] In the field of polymer processing technology, the manufacture of natural or synthetic rubber and other elastomers has traditionally been completed through processing such as hot pressing and vulcanization. Later, with the development of materials and technologies, original applications such as injection molding It can also be used as a processing tool for the manufacture of elastomers in the processing technology of the plastic industry. [0003] Among them, the injection molding processing technology disclosed in the plastic industry is to extrude the molten raw material through high pressure, and inject it into the inner mold chamber of the mold under the closed mold state through the closed flow channel. Therefore, in ord...

Problems solved by technology

[0005] The front-opening molding processing system with multi-mode stations constructed by discs has disclosed the technical means of separating the injection and vulcanization procedures, but it uses the discs to carry the technical content of most vulcanization molds. In terms of application, it is necessary to consume a lot of money. In addition to driving the disc and most of the vulcanizing molds on it, it also causes rigidity in the use of the process. It cannot adapt to changes in the actual process and the vulcanizing molds to be used must be changed according to the disc. The preset positions of most of the vulcanizing molds are used sequentially and are difficult to adjust, and cannot respond to changes in rubber molding processing conditions. If conditions change, the entire disc and most of the vulcanizing molds on it must be stopped at the same time The operation can only be continued after the conditions are met. Obviously, in terms of industrial utilization, the technical content of the application of the disk to drive most vulcanization molds is only a waste of energy, delays the process and lacks the possibility of flexible adjustment. It is obviously lacking in industrial applications. Competitiveness
