Definitions

  • the hydraulic press is used for mold opening and closing, and the injection molding part of the injection molding machine is directly injection-molded into the hot runner molding mold. After cooling, the mold is opened to take the diaphragm. While greatly reducing investment in production equipment and greatly reducing production costs, its production efficiency has been greatly improved. The amount of product shield is stable and reliable, and the surface finish is high. It is particularly suitable for the production of large diaphragms. Fourth, it uses a plastic diaphragm with a hot runner function. The molding mold not only ensures It has good fluidity after the formation, and it has laid a good foundation for the formation of thin-walled or large or extra large plastic diaphragms.
  • the combination of the hot runner molding mold and the injection molding part of the injection molding machine is the third feature of the present invention.
  • the "S: meter" of this technical solution solves the problem that the existing injection molding machine is affected by its mold structure and cannot be injected into the filter press.
  • the problems of plastic diaphragms, especially the injection molding of thin-walled plastic diaphragms, are solved.
  • the hot runner molding mold adopts hydraulic press mold clamping and opening, and the injection part of the injection molding machine is the fourth feature of the present invention.
  • the plastic diaphragm molding mold adopts two-stage mold clamping.
  • the first mold clamping forms the cavity of the plastic diaphragm molding mold.
  • the thickness of the cavity is larger than the actual size of the plastic diaphragm molding.
  • the injection molding machine The injection part of the plastic injection mold is forced to be injected into the cavity of the plastic diaphragm, and the plastic diaphragm forming mold is quickly closed for the second time to uniformly squeeze the plasticized plastic in the cavity of the plastic diaphragm into each part of the cavity. After forming and cooling, the film can be taken out by opening the mold.
  • Embodiment 2 On the basis of Embodiment 1, the hot runner 3 is made of a conductive heating material (the hot runner material itself has a function of self-heating after being energized, such as a heating ceramic, etc.) and the temperature is adjustable.

Abstract

L'invention concerne un procédé servant à fabriquer une membrane en plastique et un dispositif servant à mettre en application ce procédé. Après avoir réchauffé la matière plastique et l'avoir plastifiée au moyen d'une machine à injection, on l'injecte dans le conduit chaud d'un moule utilisé pour façonner cette membrane en plastique à travers un ajutage réchauffé pénétrant dans la cavité du moule. Au moment de son refroidissement, on ouvre le moule afin d'en retirer la forme moulée. Cette structure de transport par conduit chaud fait en sorte que la matière plastifiée par une machine à injection s'écoule uniformément dans la cavité de façonnage de la membrane en plastique, ce qui permet d'obtenir une membrane possédant des parois minces de largeur maximale. Ce moule combiné à la partie injection de la machine à injection présente l'avantage de résoudre les problèmes posés par un cycle de fabrication long et un manque d'efficacité, ainsi que des coûts élevés et un manque de flexibilité de la membrane, ce qui existe dans l'état actuel de la technique. L'invention permet, en particulier, de résoudre le problème de la fabrication d'une membrane à paroi mince.
