Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator door foaming molds, specifically a multi-station refrigerator door foaming mold. Background Technique

[0002] The multi-station refrigerator door foaming mold is an important tool for door liner foaming and forming in the manufacturing process of refrigerators or freezers. It is usually used in conjunction with a multi-station door foaming machine to improve production efficiency. This kind of mold usually has a complex structure and precise dimensional requirements to ensure that the produced refrigerator door liners have good heat insulation performance and appearance quality.

[0003] A multi-station refrigerator door body foaming mold disclosed in the existing patent publication number CN215825771U includes a lower mold and a sphere. When in use, the multi-station refrigerator door body foaming mold is externally connected to a power supply. First, take the lower mold, pull the sphere, so that under the action of the spring, the limiting block is driven to retract into the mounting seat, and then place the lower mold on the base. Then release the sphere, and the spring resets to drive the limiting block to snap into the limiting groove of the lower mold, so that the lower mold can be fixed on the base. Secondly, after the lower mold is fixed, the corresponding door body and materials can be placed into the interior of the lower mold. Then start the second telescopic cylinder to drive the upper mold to move downward and fit with the lower mold. Then rotate the fastening rods on both sides of the lower mold, so that the rubber clamping blocks on the inner side wall are driven to snap into the clamping grooves of the upper mold, so that the upper mold and the lower mold can be fixed together, and then foaming can be carried out. Finally, after the door body is foamed, start the first telescopic cylinder inside the installation groove, so that it moves upward, driving the upper movable plate to move upward, and pushing the foamed door body out of the lower mold, and finally complete the work of using the refrigerator door body foaming mold.

[0004] During the foaming process, it is necessary to fix the upper refrigerator door panel to facilitate foaming together with the lower refrigerator door panel. The clamping of the upper refrigerator door panel by the above device is relatively simple, and the practicability still needs to be improved. In view of the above problems, a multi-station refrigerator door foaming mold is proposed. Summary of the Utility Model
