Background

In the refrigerator industry, the liner is used as an important component of a refrigerator, and the forming principle of the liner is generally the process of heating, softening, bubbling and wrapping ABS and HIPS plates on a main body mold core of a liner plastic suction mold by plastic suction forming equipment, then carrying out vacuum adsorption, cooling forming and demolding to obtain the refrigerator liner. The functions of the internal structure of the refrigerator are gradually increased, the design of the liner of the refrigerator also tends to be complicated, the design of a liner plastic suction mold has higher requirements, the liner usually has more various ribs and barb structural designs which are inwards concave, and the liner is difficult to directly separate from the mold after plastic suction is finished. For the lining with simpler structure and smaller draft angle, a demoulding mechanism is not needed and air blowing expansion is needed; but to the more inside lining of stepping down, the mould increases barb mechanism and steps down, sets up the drawing of patterns work of plastic uptake inside lining for mould large face position even.

The traditional demoulding device of the refrigerator lining plastic suction mould has the following problems: (1) poor stability: the sliding block motion balance of the traditional demoulding device is maintained only by the linear guide rail structures of the two sliding blocks, and the double-sided sliding block is easy to operate asynchronously after long-term use because the abrasion of the linear guide rail on one side is deepened by inertia or because a mechanism (a common power mechanism is a cylinder, hereinafter referred to as the cylinder for short) for providing power for the sliding block of the mould is loosened by a fixing part. (2) The maintenance difficulty is large: the cylinder of the traditional demoulding device is close to the middle position inside the mould core, and the space is narrow and small, so that the traditional demoulding device is difficult to expand for maintenance. Therefore, a demolding device for a refrigerator liner blister mold is needed to solve the above problems.

The utility model has the following beneficial effects:

1. according to the utility model, the supporting plate is fixed at the open structure of the mold core main body, and the air cylinder is arranged on the supporting plate, so that the air cylinder is moved to the outer side of the mold core main body from the interior of the mold core main body, and the later maintenance of the air cylinder is facilitated, and other parts are also facilitated to be maintained because no space is occupied by the air cylinder in the mold core main body.

2. According to the utility model, by adding two groups of positioning sleeve positioning column structures which are parallel to each other, when the cylinder pushes the bearing plate to move, the positioning columns limit the left and right directions of the bearing plate to swing, so that the movement stability of the bearing plate is effectively increased, the non-parallelism of the movement of the parting slide block caused by the swinging of the bearing plate is reduced, and the movement stability of the whole device is ensured.

Of course, it is not necessary for any product in which the utility model is practiced to achieve all of the above-described advantages at the same time.
