Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator production and processing, in particular to a sealing mechanism for a refrigerator center beam foaming mold. Background Art
[0002] Currently in the refrigerator industry, vertical beams are important supporting components inside the refrigerator. They are used to support the refrigerator body in the up, down, left and right directions to prevent it from being easily deformed by external forces. In order to ensure the thermal insulation performance of the refrigerator, cyclopentane foam is usually filled in the vertical beams to isolate the temperature.
[0003] The foaming production process for refrigerator vertical beams usually involves placing the vertical beam shell into a special foaming fixture mold, and then injecting foaming material into the mold through the circular injection holes of the mold and the vertical beam after the fixture mold is locked and closed.
[0004] The vertical beam foaming fixture mold is divided into two parts, the upper fixture and the upper mold, and the lower fixture and the lower mold are all connected and fixed by bolts. The upper mold includes the upper mold plate, locking roller, etc., and the lower mold includes the lower mold plate, various baffles, spring hinges, etc. In the natural state, the four-side baffles of the mold are pulled outward by the spring hinges in a free state without other external forces to open at a certain angle. At this time, the baffles and the horizontal plane of the lower mold plate are at an obtuse angle, which is convenient for the placement and removal of the vertical beam shell. After the upper and lower molds are closed, the four-side baffles of the lower mold are closed inward under the locking force of the upper mold locking roller until the baffles and the horizontal plane of the lower mold plate are at a 90° vertical angle. At this time, the mold is locked, and the injection gun injects material into the vertical beam through the circular injection hole on the upper fixture mold.
[0005] In order to prevent the leakage of excess foaming material during the foaming process, it is necessary to take measures to seal the injection port after the injection is completed. The sealing method in the traditional vertical beam foaming production process has the following problems:
[0006] 1. Paste a plastic rebound sheet to block the material at the injection hole of the vertical beam shell: This method has problems such as limited sealing ability, high material and labor costs, and unstable quality.
[0007] 2. Use manual sealing plugs: This method has problems such as low efficiency and high risk. Utility Model Content

[0011] As a further solution of the utility model: a first limiter is arranged on the vertical plate near the first telescopic member, and the first limiter is used to limit the telescopic position of the first telescopic member.
