Embodiment Construction

[0008] Referring to the accompanying drawings, the present embodiment is composed of the template part 1, the mold 2 and the ejector mechanism 3 as a turning mechanism, and the turning arms 4 are arranged symmetrically on both sides of the turning mechanism, and the supporting rods 6 on both sides of the turning arm 4 and the frame 5 Hinge with hinge axis 7.

[0009] In specific implementation, on the turning arm 4, a rotating handle 8 is provided, and the center of gravity of the turning mechanism is set slightly lower than the rotating shaft of the rotating handle 8. Turning the rotating handle 8, the manual turning of the turning mechanism can be implemented, and the dead point can be utilized. The position positioning is locked. Electric drive can also be used to turn over, and through the optimized electrical circuit design, the fixture can be controlled to turn over at different angles.

[0010] Properly set the length, width and depth of the frame 5 to ensure that ther...

Abstract

A turn over type foaming clamp consists of template part, turn over mechanism assembly composed of mold and ejection mechanism, turn over arm symmetrically set at two sides of turn over mechanism, and support lever hinged with turn arm. In the process of forming of refrigerator casing, the foaming liquid is promoted to flow, so making more uniformly foaming and better thermo-insulation. Said invention is more adaptive for thin casing.

Description

Technical field: [0001] The invention relates to a foaming device for a refrigerator box, more specifically a foaming fixture for a refrigerator box. Background technique: [0002] The refrigerator box, including the refrigerator door, is made to have the function of heat insulation through foaming in the refrigerator shell. In order to ensure the heat insulation effect, the foaming must be uniform. But, especially for some smaller casings, the inner cavity of the casing is very thin, and the flow of the foaming liquid therein is not smooth, resulting in uneven foaming, affecting product quality and increasing the reject rate. Invention content: [0003] The technical problem to be solved by the present invention is to avoid the shortcomings of the above-mentioned prior art, and to provide a flip-type foaming fixture. While foaming, the fixture can drive the refrigerator box to turn over together, so as to promote the foaming liquid in the box. The flow in the body makes...
