TECHNICAL FIELD

[0001] The utility model relates to the field of household appliance manufacturing, especially to a foaming equipment for refrigerator production. BACKGROUND

[0002] The existing foaming equipment for refrigerator production often adopts traditional bolt fixing or simple buckle connection when fixing the pressing plate. This fixing method is not only cumbersome to operate, but also the pressing plate is prone to deviation or loosening during the foaming process due to the expansion force of the foaming agent and the thermal stress of the material, resulting in uneven foaming and affecting the heat preservation effect of the refrigerator. In addition, the traditional fixing method may also cause gaps between the pressing plate and the mold, causing the foaming agent to leak and further affecting the product quality.

At the same time, the gap between the mold and the parts is prone to residual foaming agent and other impurities, which is difficult to clean thoroughly. Long-term accumulation may cause the performance of the equipment to decline, or even damage. SUMMARY
