Blister mold for producing fresh-keeping cabinet integrated plastic liner

Abstract

The invention relates to a blister mold for producing a fresh-keeping cabinet integrated plastic liner, which solves the technical problems of the prior art that the universality is poor and the like.The blister mold for producing the fresh-keeping cabinet integrated plastic liner comprises two end bottom molds, wherein at least one intermediate bottom mold is arranged between the two end bottommolds, a blister mold cavity is formed between the end bottom mold and the intermediate bottom mold, the bottom of a chamber of the blister mold cavity is provided with a guide surface-I forming inclined surface which is arranged along the length direction of the blister mold cavity and is arranged in a downward inclination manner, as well as a guide surface-II forming inclined surface which is arranged along the length direction of the blister mold cavity, the guide surface-I forming inclined surface and the guide surface-II forming inclined surface form an angle less than 180 degrees, and the mold also comprises a drainage groove forming groove formed in the guide surface-I forming inclined surface and the guide surface-II forming inclined surface. The blister mold has the advantage thatthe universality is improved.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a plastic-absorbing mold for manufacturing an integrated plastic liner of a fresh-keeping cabinet. Background technique [0002] Cabinets such as fresh-keeping cabinets are generally equipped with a liner for receiving water. [0003] Existing liner, it generally adopts a plurality of pieces of stainless steel iron sheets to be welded and processed, and its inside forms a groove body after welding. Welding is carried out with custom-made fixtures, which obviously cannot meet the requirements of mass production. At the same time, some inventors have improved this by using injection molding to manufacture blister molds. However, the scope of application of existing blister molds is very small, and one mold can only process inner tanks of one size, resulting in inner tanks of different lengths. The gallbladder needs to manufacture and process different molds. This method not only h...

Welding is carried out with custom-made fixtures, which obviously cannot meet the requirements of mass production

At the same time, some inventors have improved this by using injection molding to manufacture blister molds. However, the scope of application of existing blister molds is very small, and one mold can only process inner tanks of one size, resulting in inner tanks of different lengths. Gallbladder needs to manufacture and process different molds. This method not only has very high cost, but also has very poor versatility and very unreasonable design.
