Refrigerator door liner injection molding machining device capable of safely and quickly demolding

Abstract

The invention relates to the technical field of injection molding of refrigerator door liners, and discloses a refrigerator door liner injection molding machining device capable of safely and quicklydemolding. The refrigerator door liner injection molding machining device capable of safely and quickly demolding comprises a workbench, four supporting bases are fixedly connected to four corners ofthe bottom of the workbench, a first hydraulic cylinder fixedly is sleeved with the bottom of the workbench, an injection mold is fixedly arranged at the top of the workbench, two sets of supporting rods are symmetrically and fixedly connected to the top of the workbench, the number of each set of supporting rods is two, a top plate is fixedly connected between the top ends of the two sets of supporting rods, a second hydraulic cylinder is fixedly connected to the bottom of the top plate, and the injection mold comprises a top mold, a bottom mold and a refrigerator door liner. According to therefrigerator door liner injection molding machining device capable of safely and quickly demolding, the problems that hanging walls are arranged on refrigerator door liners of existing refrigerators,so that the contact area between the refrigerator door liners and a mold cavity is increased, and the demolding difficulty of the refrigerator door liners is increased are solved.

Description

technical field [0001] The invention relates to the technical field of injection molding of refrigerator door linings, in particular to an injection molding processing device for refrigerator door linings capable of safe and rapid demoulding. Background technique [0002] The refrigerator door needs to seal and isolate the interior of the refrigerator from the external environment, so the requirements for its dimensional accuracy are high, and the refrigerator door liner is a component of the refrigerator door, so whether its size is accurate or not directly affects the refrigerator. The airtightness of the door, so the refrigerator door liner generally adopts the integral molding process of the mold in the production process. [0003] In order to increase the capacity of the refrigerator and improve the utilization rate of the refrigerator space, the refrigerator door liner of the refrigerator is generally designed with a wall, so as to hang some trays and trays for placing...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a refrigerator door liner injection molding processing device capable of safe and quick demoulding, which solves the problem that the refrigerator door liners of existing refrigerators are designed with wall hangings, thereby increasing the size of the refrigerator door liner and the mold. The contact area of ​​the mold cavity increases the difficulty of demoulding the refrigerator door.
