Presses for plastic materials

Abstract

The invention relates to a press machine for a plastic material. The press machine is used for stamping the plastic material, and comprises a machine frame, a hydraulic system, a quick cylinder and a moving oil cylinder, wherein the hydraulic system is arranged on the machine frame; the quick cylinder is arranged at the upper end of the machine frame and is connected with the hydraulic system; the moving oil cylinder is arranged at the output end of the quick cylinder and is connected with the hydraulic system; the machine frame is provided with a workbench; a lower mold is fixedly arranged on the workbench; the quick cylinder and the moving oil cylinder are positioned above the workbench; an upper mold matched with the lower mold is arranged on the moving oil cylinder; the moving oil cylinder comprises a moving cylinder body and a moving plunger; the moving cylinder body is fixedly arranged at the output end of the quick cylinder; the moving plunger extends out of the moving cylinder body; a pushing plate is fixedly arranged on the moving plunger; the pushing plate protrudes in the direction facing away from the workbench to form a propping block; the propping block is made of an elastic material; a positioning plate which extends to the pushing plate is arranged on the moving cylinder body; the propping block is propped against the bottom surface of the positioning plate; telescopic rods are arranged on two sides of the moving cylinder body; one end of each telescopic rod is connected with the moving cylinder body, and the other end of each telescopic rod is connected with the pushing plate.

Description

technical field [0001] The invention relates to a press for plastic materials. Background technique [0002] In the processing of plastic materials, mechanical presses are generally used to realize stamping at present. The mechanical press is a forging machine driven by a crank connecting rod or a toggle mechanism, a cam mechanism, and a screw mechanism. It is a machine tool used for pressure processing of materials. Component. However, due to the problems that the mechanical press is easy to wear and the follow-up maintenance costs are high, in addition, the precision requirements of each component in the mechanical press are high, resulting in high cost requirements and the inertial pressure of the mechanical press. , so that the defective rate in the stamping of plastic materials remains high. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating in order to create a press machine with a new structure, so that it has more ...
