A mold for producing special-shaped injection parts with fast mold opening function

Abstract

The invention discloses a mold for producing special-shaped injection molded parts with the function of rapid mold opening, which comprises an upper mold, a transmission assembly and a fixing assembly. The upper mold is provided with a transmission assembly, and the transmission assembly is fixedly connected with a fixing assembly. When the hydraulic lifting rod controls the upper die to move downward, the telescopic end of the hydraulic lifting rod controls the sliding plate to continue to move down and press the moving plate, so that the resisting rod gradually extends downward in the perforation, which is convenient for controlling the resisting rod to squeeze the transmission rod 1. The transmission rod 2 can be squeezed by the lateral movement of the transmission rod 1, so that the transmission rod 2 can move downward in the longitudinal movable chamber, and the transmission rod 2 can pass through the opening during the downward movement, and the movement in the moving chamber can be controlled. The block is squeezed, so that the moving block can compress the return spring in the moving cavity to move laterally, and then drive the fixed rod to penetrate the fixed hole through the jack hole, which can enhance the connection between the upper die and the lower die, and avoid the upper die. During the injection molding process, the upper hot air lifts up.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a mold for producing special-shaped injection molded parts with the function of rapid mold opening. Background technique [0002] Injection molds are divided into thermosetting plastic molds, automobile molds, and thermoplastic plastic molds according to their molding characteristics; Injection molds, etc., in which hot pressing molds can be divided into three types: overflow type, semi-overflow type, and non-overflow type according to the overflow method, and injection molds can be divided into two types: cold runner mold and hot runner mold according to the gating system; The installation and disassembly methods can be divided into two types: mobile type and fixed type. [0003] Existing molds for the production of special-shaped injection molded parts with rapid mold opening function usually use hydraulic pumps and hydraulic lifting rods to control the upper mold, so ...

Problems solved by technology

[0003] Existing molds for the production of special-shaped injection molded parts with rapid mold opening function usually use hydraulic pumps and hydraulic lifting rods to control the upper mold, so as to realize rapid mold opening and closing between the upper mold and the lower mold, but because the hydraulic lifting rod It is movably connected with the upper mold. After the upper mold and the lower mold are closed, when the mold is injected into the mold, the upper mold will be instantly lifted by a large amount of hot air, which will cause the joint between the upper mold and the lower mold to be easily misaligned, and the use is unstable. , resulting in a reduction in the production quality of the workpiece in the mold
