A rubber injection molding process with multiple colors or different physical properties

Abstract

The invention relates to a multicolor or different-physical-property rubber injection molding process. The process comprises the following steps: 1, prefabricating a pigment and an isolation layer; 2,rolling the pigment, and blanking the appearance; 3, rubbing, kneading and pressing the pigment into a mold cavity to be tightly attached to the mold cavity; 4, attaching the isolation layer to the pigment; 5, vacuumizing and injecting a rubber raw material; and 6, taking out a finished product after vulcanization molding. The injection molding process has the advantages that the base material (injection material) is pressed or the specially-made screen cloth is placed on the pigment, so that the injection material is isolated from the pigment to a certain extent through the specially-made screen cloth, cross color caused by taking away the pigment is avoided, and the screen cloth can improve the strength of the product.

Description

technical field [0001] The invention belongs to the field of rubber injection molding, in particular to a rubber injection molding process with multiple colors or different physical properties. Background technique [0002] In the field of traditional rubber injection molding, it is difficult to inject rubber materials with different colors and physical properties on the same product. Instead, a single rubber material is usually used for injection molding. However, as people now have different styles and characteristics of products Higher requirements require simultaneous injection molding of rubber materials of different colors or different physical properties on the same product. Using the existing production process, it is easy to carry color materials (different colors, different physical properties) with the rubber materials during the injection process. Go, and cross-color occurs, can not be achieved. Contents of the invention [0003] In order to solve the above pr...
