Mold opening device for foaming mold of refrigerator door body

Abstract

The invention relates to the technical field of foaming mold opening devices, and discloses a refrigerator door foaming mold opening device which comprises a base and a mold, hydraulic rods are mounted on the inner walls of the two sides of the base, a connecting plate is mounted at one end of each hydraulic rod, a V-shaped positioning block is mounted on the other side of each connecting plate, and a limiting strip is mounted at the top of each V-shaped positioning block. A lower mold is arranged above the base, and an upper mold is arranged above the lower mold; and a placement groove is formed in the upper mold inner groove. According to the design, after grouting is conducted through the grouting holes by the grouting pipe and the molds are cooled and formed, the V-shaped positioning block is driven by the hydraulic rod to conduct relative opening and closing stretching movement, so that the V-shaped positioning block drives the upper mold and the lower mold to be separated, and in the opening and closing process, after the upper mold ascends, the mold is inconvenient to abut against by the position of the abutting plate; and the mold is separated from the inner mold groove, workers can take the mold conveniently, manual dragging is not needed, labor consumption is reduced, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a foam mold opening device, in particular to a mold opening device for a refrigerator door foam mold. Background technique [0002] In recent years, with the rapid development of my country's refrigerator market, the production and sales of refrigerators in various enterprises have continued to grow. The door body of the refrigerator is composed of upper and lower side cards, a door shell, a door bladder and a foaming liquid. There are card slots on the upper and lower sides, which are inserted into the two ends of the door shell respectively. The installation of the door bladder and the foaming liquid requires a mold. The assembled edge card and the door shell are placed on the upper mold of the mold, and the door bladder is placed on the upper mold. The lower mold of the mold, when the mold is opened, the foaming machine injects the set foaming liquid into the door, closes the mold, and the foaming liq...

Problems solved by technology

In this production process, the upper mold of the mold needs to be manually opened and closed manually; due to the large number of molds and the heavy weight of the mold, repeated manual operations not only increase physical energy consumption, but also reduce production efficiency

[0003] A Chinese patent discloses a mold opening device for a refrigerator door foam mold (authorized notification number CN209063394U). This patented technology uses a motor as a driving mechanism to move the upper template up and down to open and close the mold, reducing the workload of workers. The limit column provided on the lower surface of the formwork and the limit groove provided on the upper surface of the lower formwork can make the upper formwork and the lower formwork can be aligned accurately when the mold is closed to ensure the quality of the product. However, in the grouting process, due to the The vent hole will be partially bonded to the vent hole after the mold is formed, so in the process of taking out the mold, manual removal of the mold will consume too much physical strength
