Thermosetting injection molding machine capable of preventing coking phenomenon caused by high temperature of feeding port

Abstract

The invention relates to the technical field of injection molding equipment, and provides a thermosetting injection molding machine capable of preventing coking caused by high temperature of a feeding port. The thermosetting injection molding machine comprises a machine body, wherein the inner wall of the machine body is fixedly connected with a cavity, the outer wall of the cavity is fixedly connected with a water tank, and the outer wall of the water tank is fixedly connected with an air pressure bin. According to the thermosetting injection molding machine capable of preventing the coking phenomenon caused by the high temperature of the feeding opening, the mold core is connected with the mold cavity, the feeding opening starts injection molding, when the temperature is too high, water in the water tank is evaporated, water vapor pushes a push plate, the push plate is pressed to compress a spiral spring, the push plate pushes a push block through a push rod, the push block enables the sliding block to slide through the linkage rod on the outer wall of the push block, the sliding block horizontally moves to drive the connecting block, the connecting block changes the resistance value of the sliding rheostat, the sliding rheostat changes the temperature of the heating device, and the phenomena that due to the high temperature, the plastic outer wall is burnt and carbonized, the carbonized product is not attractive, and the service life of the product is shortened are prevented.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a thermosetting injection molding machine that prevents coking at a feeding port when the temperature is high. Background technique [0002] Injection molding machine is a main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Injection molding machines can produce various daily necessities. The demand for injection molding products is large. With the development of the times, injection molding The machine can produce daily necessities in large quantities, with high efficiency, high production precision and low manpower consumption for mechanized production. [0003] In the prior art, thermosetting injection molding machines have high requirements on temperature because the plastics used in thermosetting injection molding machines are thermosetting and irreversible. The ov...

Problems solved by technology

[0003] In the prior art, thermosetting injection molding machines have high requirements on temperature because the plastics used in thermosetting injection molding machines are thermosetting and irreversible. The overall temperature of the injection molding machine is often affected by the heating device and the plastic in the molten state, and the heating device cannot be constant. The internal temperature of the injection molding machine will cause carbonization at the feeding port, and the high temperature cannot reduce the temperature to the set value. Therefore, a thermosetting injection molding machine that prevents the coking phenomenon at the high feeding port temperature has emerged as the times require.
