Problems solved by technology

Most of the current hot runner systems use gun drills to process the runners, resulting in dead angles and roughness in the runners, which lead to a series of problems, such as glue retention in the runners, difficulty in clearing glue, and difficulty in color change. , so it is necessary to design a system that can solve these problems, so as to avoid the occurrence of the above problems

Embodiment

[0034] Example: superimposed compression sealing hot runner system

[0035] See attached figure 1 ~ attached Image 6 As shown, a superimposed compression type sealing hot runner system, the distribution plate of the superposition compression type sealing hot runner system is composed of two parts spliced, that is, the first plate 4 of the distribution plate and the second plate 11 of the distribution plate Superimposed splicing composition. And the flow channel 12 is formed on the surface of the first block 4 of the distribution plate. However, the flow channel in the prior art is formed inside a steel plate by gun drilling. Because the technical solution of the present invention opens the flow channel 12 on the surface of the first plate 4 of the distributor plate, the processing technology is simple, and the formed flow channel will not have dead angles, roughness and the like.

[0036] In order to overlap and splice together the first plate 4 of the manifold and the se...

Abstract

The invention discloses an overlapped and compressed type sealant hot runner system. A manifold of the overlapped and compressed type sealant hot runner system is formed by overlapping a first manifold plate and a second manifold plate, and a runner is formed in the surface of the first manifold plate. According to the overlapped and compressed type sealant hot runner system, the runner is formed in the surface of the first manifold plate, so that the formed runner is smooth and free of dead angles, complicated nozzle runner distribution can be achieved, the pressure drop in the runner is reduced by 10%, the processing technology is reduced, and the cost is saved.

Description

technical field [0001] The invention relates to a superimposed and compacted glue-sealing hot runner system, which belongs to the technical field of auxiliary equipment for injection mold systems. Background technique [0002] At present, with the development of the plastic manufacturing industry, people have higher and higher requirements on the performance and quality of plastic products. Injection molds play a very important role in the plastic molding industry. The optimization and improvement of injection molds is the key point to accelerate the development of the injection molding industry. Hot runner technology was first produced in the 1940s, and its production is a major technological change in the injection mold industry. The hot runner system keeps the plastic in the runner and gate in a molten state by heating or insulating the gating system of the mold, thereby avoiding the formation of condensate in the gating system. Compared with ordinary runner technology,...
