Abstract

The utility model provides a refrigerator door shell blister mold and a refrigerator. The blister mold includes a flange forming mold bar disposed around the top of a mold cavity. Each flange forming mold bar is provided with a drive cylinder assembly for propelling the flange forming mold bar inward or outward. When the flange forming mold bar is pushed inward, the refrigerator door shell is pressed to form a flange. When the flange forming mold bar is pushed outward, the refrigerator door shell with the flange is completely exposed in the mold cavity. The refrigerator includes a refrigerator door shell formed using the refrigerator door shell blister mold. The utility model can achieve integrated molding of the refrigerator door shell and the flange during blister molding, avoiding the problem of gaps in appearance. It also has the advantages of easy demolding and a high yield rate.

Description

Refrigerator door shell plastic uptake mould and refrigerator

Technical Field

The utility model belongs to the technical field of refrigerator molds, and particularly relates to a refrigerator door shell plastic suction mold and a refrigerator.

Background

In the prior art, as shown in fig. 1, the antique refrigerator (large R angle, round product in visual sense) has a door shell which is in order to meet the front seamless requirement, so that the manufacturing mode of the traditional steel plate door structure is abandoned, and the manufacturing mode of integral injection molding is mostly selected.

The utility model patent application with publication number CN109696019A, named as a novel door shell structure adopting an integral plastic suction process, discloses a retro refrigerator door shell manufactured by adopting a plastic suction mode, but the manufactured refrigerator door shell 1 is shown in figure 3 and only provided with a groove 2, and the flange 3 (shown in figure 2) at the rear side of the refrigerator door shell still needs to be spliced again although the front seamless requirement is met, so that the effect of one-time molding of the refrigerator door shell cannot be met, and the problems of high manufacturing cost and gaps in appearance still exist.

Disclosure of utility model

The utility model aims to overcome the defects of the prior art and provides a refrigerator door shell plastic uptake mould capable of integrally forming a refrigerator door shell with a flanging structure.

The utility model also provides a refrigerator using the refrigerator door shell plastic sucking mould.

The utility model provides a plastic suction mold for a refrigerator door shell, which comprises a molding mold base and a plastic suction mold body positioned on the molding mold base, wherein a mold cavity for molding the refrigerator door shell is arranged in the molding mold base, a moving mechanism for demolding is arranged around the plastic suction mold body, the moving mechanism comprises flanging molding mold strips which are arranged around the top of the mold cavity in a surrounding manner, driving cylinder groups for pushing the flanging molding mold strips to move inwards or outwards are arranged outside the flanging molding mold strips, when the flanging molding mold strips are pushed inwards, the refrigerator door shell is pushed out of flanging, and when the flanging molding mold strips are pushed outwards, the refrigerator door shell with the flanging can be completely exposed in the mold cavity.

A second aspect of the present utility model provides a refrigerator comprising a refrigerator door shell molded using the refrigerator door shell plastic suction mold described above.

The utility model can realize the integral molding of the refrigerator door shell and the flanging by utilizing the telescopic flanging molding die strip during plastic suction, and the flanging can be directly overlapped on the refrigerator door liner, thereby not only avoiding the obvious gap problem in appearance, but also having the advantages of convenient demoulding, high yield and high production efficiency.

Detailed Description

Referring to fig. 4, the plastic suction mold for a refrigerator door shell provided in this embodiment includes a molding mold base 4 and a plastic suction mold body 5 located on the molding mold base 4, the molding mold base 4 is provided with a mold cavity 41 for molding the refrigerator door shell 1, the plastic suction mold body 5 is provided with a molding die 51 matching the shape of the mold cavity 41, referring to fig. 5, the periphery of the plastic suction mold body 5 is provided with a moving mechanism 6 for demolding, the refrigerator door shell with a flange 3 in fig. 2 is in demolding process, the flange 3 can limit detachment of a molding mold body in the plastic suction mold body 5 after being integrally molded with the refrigerator door shell 1, so that in the prior art, the plastic suction mold body is difficult to be integrally molded with the flange 3 in the plastic suction process of the refrigerator door shell 1.

Before the plastic suction, the cylinder group 62 is driven to push in each flanging forming die strip 61, the flanging forming die strips 61 push out the flanging 3, and after the plastic suction, the cylinder group 62 is driven to pull out each flanging forming die strip 61, so that the demoulding of the formed refrigerator door shell with the flanging structure in the die cavity 41 is not influenced. Referring to fig. 9, the formed refrigerator door shell is placed into a foaming mold to form a refrigerator door with an inner container 7, and a door seal 8 is assembled to form an integral refrigerator door without gaps around.

In this embodiment, referring to fig. 7, a door handle molding die bar 8 is disposed below a flanging molding die bar 61 on one side, the flanging molding die bar 61 is integrally molded with the door handle molding die bar 8, and a corresponding driving cylinder group 62 drives the flanging molding die bar 61 to push inwards or outwards together with the door handle molding die bar 8. The purpose is that when the refrigerator door shell with the door handle at one side is formed, the refrigerator door shell can be formed together with the flanging, so that the working procedures are saved.

In this embodiment, referring to fig. 8, connecting blocks 9 are uniformly distributed on the rear wall of the flanging die strip 61, the other ends of the connecting blocks 9 are connected to the push rod 10, and the piston rods of the cylinders in the driving cylinder group 62 are all installed in the push rod 10. The purpose is to ensure the synchronous movement of the respective flange forming die bars 61 and to ensure the flatness of the flange.

The embodiment also provides a refrigerator, which comprises the refrigerator door shell formed by using the refrigerator door shell plastic suction mold.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
