Double-cylinder mold opening device of injection molding machine and working method thereof

Abstract

The invention discloses a double-cylinder mold opening device of an injection molding machine. The double-cylinder mold opening device comprises a supporting plate, a fixed mold, a movable mold and aninjection molding box. The invention relates to the technical field of garment materials. According to the double-cylinder mold opening device of the injection molding machine, a first hydraulic telescopic rod is fixedly connected with a push rod, an ejector rod is fixedly connected with a sliding cylinder through a push plate, the push rod is movably connected with the sliding cylinder through aspring, the push rod can drive the sliding cylinder to move through the cooperation of a sliding plate, the spring and a cylinder cover, the ejector rod can move within a certain range while the first hydraulic telescopic rod can adjust the position of the ejector rod, it is guaranteed that the position of the ejector rod is not affected by the first hydraulic telescopic rod when accurately positioned, a positioning block limits the position of a positioning rod from the right side of the positioning rod, a limiting column and a limiting plate limit the position of the push plate from the left side of the push plate, and therefore the accuracy of the positions of the push plate and the positioning rod is guaranteed, and then the accuracy of the position of the ejector rod is guaranteed.

Description

technical field [0001] The invention relates to the technical field of clothing fabrics, in particular to a double-cylinder mold opening device for an injection molding machine and a working method thereof. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. Injection molding machines are usually composed of injection system, mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc. [0003] In the existing injection molding machine, in order to facilitate the remova...
