Refrigerator door foaming outer clamp

Abstract

The invention relates to a refrigerator door foaming outer clamp. The clamp comprises a bottom plate, an upper clamping plate hinged to the rear side of the bottom plate, and a lower clamping plate arranged at the top of the bottom plate and connected with the bottom plate in a lifting mode, wherein a front locking frame extending downwards is arranged on the front side of the upper clamping plate, a locking notch with a backward opening is formed in the bottom of the rear side of a front locking piece, a front locking strip is connected to the front side of the bottom plate in a left-right horizontal sliding mode, a front locking block is arranged on the front side of the front locking strip, when the clamp is in a state for mold closing, the locking notch is located in the stroke path ofthe front locking block, a power rod horizontally sliding left and right is arranged at the top of the bottom plate, a hinge rod is connected between the power rod and the lower clamping plate, the top of the hinge rod is hinged to the lower clamping plate, the hinge axis horizontally extends front and back, the bottom of the hinge rod is hinged to the bottom plate, and the hinge axis horizontally extends front and back. According to the design of the clamp, the hinge rod is connected between the power rod and the lower clamping plate, so that the lower clamping plate can clamp a mold upwards, the assembly and clamping performance is better, the clamp can enable the mold to be directly connected to a conveying line for production conveniently, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of foam molding molds for refrigerator door bodies, in particular to a foam outer fixture for refrigerator door bodies. Background technique [0002] In order to ensure good airtightness when the foam molding inner mold of the refrigerator door is working, it is usually necessary to set a fixture outside the foam molding inner mold to pressurize the foam molding inner mold. The existing fixture can only be clamped downward Applying pressure will cause the mold to sink during clamping, which will easily lead to damage to the interface. At the same time, the upper and lower clamping of the mold is not synchronized, resulting in unstable clamping, and the forming mold cannot be directly connected to the production line. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a foaming outer fixture for a refrigerator door body. [0004...
