Abstract

The invention belongs to the technical field of rubber injection forming, and particularly relates to a high-capacity rubber injection machine. The high-capacity rubber injection machine comprises aninjection seat, wherein a hydraulic oil cylinder for injection is arranged on the injection seat; the cylinder body of the hydraulic oil cylinder for injection is connected with a material barrel; thematerial barrel is connected with an injection pipe; one side of the material barrel is connected with a first cold feeding screw extruder; and a second cold feeding screw extruder is connected to the injection pipe. During the high-capacity rubber injection of the high-capacity rubber injection machine provided by the invention, a rubber material is injected into the die cavity of a die by virtue of the second cold feeding screw extruder at first, then the material is added into the material barrel by virtue of the first cold feeding screw extruder, and the rubber material in the material barrel is injected into the die cavity under the effect of the great pressure of the hydraulic oil cylinder for injection, so that high-capacity rubber injection is realized, and the need of the existing high-capacity rubber injection is met; and the high-capacity rubber injection machine is simple in structure, capable of being improved on the basis of the existing rubber injection machine, and lowin processing difficulty and cost.

Description

technical field [0001] The invention belongs to the technical field of rubber injection molding, in particular to a large-capacity rubber injection machine. Background technique [0002] Rubber raw materials have high viscosity, poor fluidity, are not easy to inject, and are prone to scorching at high temperatures. Therefore, the compression molding method based on flat vulcanizers has always occupied a dominant position in the production of rubber products. With the rapid development of automobile, aerospace, electronic power and other industries, higher requirements are put forward for the technical performance, production cost and output efficiency of rubber products. It is difficult for traditional compression molding technology to meet this development trend of the market. The rubber injection molding technology shortens the production cycle due to the rapid vulcanization of the rubber material at high temperature, and it is easier to ensure the uniformity of vulcanizat...
