The invention discloses a silicon rubber quantitative injection device. The silicon rubber quantitative injection device comprises a hydraulic mixing feeding mechanism capable of setting a constant pressure and a hydraulic injection device capable of setting an injection stroke. An AB rubber containing chamber is arranged on the hydraulic injection device. A three-way valve is installed on the feeding end of the AB rubber containing chamber. A one-way valve is butted at a rubber inlet of the three-way valve. The hydraulic mixing feeding mechanism mixed with an AB rubber injected penetrates through a feeding channel to butt the one-way valve and the AB rubber is pressed into the AB rubber containing chamber. The hydraulic injection device provides certain pressure to push a piston rod to extrude and inject the AB rubber according to the set injection stroke. The method of hydraulic constant pressure and the design method of configurable stroke of the piston rod are adopted, and the supply of rubber injection amount can be set according to the amount of the rubber used in products, in this way, the waste of the rubber is not only reduced, but also the quality of final product formingis ensured.
Description
technical field [0001] The invention relates to silicone rubber mixing and feeding equipment, in particular to a silicone rubber quantitative injection device. Background technique [0002] At present, there are more and more silicone rubber products, and the molding method is generally injection molding. However, since the amount of rubber used in each product is different, it is necessary to quantitatively deliver the rubber according to the amount of rubber used in different products. , the existing method is to determine the amount of glue through the experience of the operator or by weighing. This method is not only very inefficient, but also inaccurate in judging the amount of glue. Contents of the invention [0003] The object of the present invention is to provide a silicone rubber quantitative injection device for the above-mentioned defects of the prior art. [0004] In order to solve the above-mentioned defects in the prior art, the technical solution provided...
