Description

Technical Field

[0001] The utility model relates to the technical field of demoulding devices for prefabricated parts, in particular to a quick demoulding device for easily disassembled prefabricated parts. Background Art

[0002] Prefabricated molds generally include plastic injection molding and sheet metal steel mold molding. Prefabricated plastic molds use polypropylene plastic granules that are injected into the pre-prepared prefabricated mold cavity after high-temperature treatment by an injection molding machine. After cooling, the prefabricated mold is formed. The use of cement prefabricated parts can shorten the construction period of construction projects and save project costs. They are widely used in airports, container terminals, building communities, landscaping, river slope protection, and water and soil engineering. Cement prefabricated molds are mostly iron molds, and cement products are heavy. The demoulding problem has always plagued construction units. In the existing cement prefabricated production process, it is not convenient to remove the prefabricated parts from the mold during demoulding. It is necessary to knock around the mold to make the prefabricated parts detach from the mold. The detachment process is relatively complicated. In addition, it is not convenient to centrally clean up the debris generated by the grinding work.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN216442774U discloses a demoulding device for cement precast parts production that is easy to clean. This patent facilitates the demoulding of precast parts and the cleaning of waste impurities through the setting of clamping mechanisms and cross bars. However, when demoulding, the mold needs to be reversed so that the mold opening faces downward. Since the mold is heavy as a whole, the labor workload will be increased. When cleaning impurities, the impurities are swept away but there is a lack of collection of impurities. Therefore, it is necessary to design a quick demoulding device for easily disassembled precast parts. Utility Model Content

[0031] During specific use, the preform in the mold is separated from the mold and falls onto the support plate 15. When the support plate 15 is subjected to the pressure of the preform, the sleeve rod 13 slides downward in the sleeve 12. At this time, the spring 14 is in a compressed state. After the preform is taken out, the spring 14 drives the sleeve rod 13 and the support plate 15 to return to their original position.

At this time, the cross bar 7 on the first clamping plate 5 and the second clamping plate 6 are in sliding motion. Under the operation of the hydraulic rod 4, the first clamping plate 5 and the second clamping plate 6 can be close to each other and clamp the undemolded mold. When the servo motor 10 is in operation, its output end can drive the rotating block 3 to rotate, and drive the rotation of the first clamping plate 5 and the second clamping plate 6 through the hydraulic rod 4, so that the mold clamped by the first clamping plate 5 and the second clamping plate 6 can be turned over so that the mold mouth faces downward, which is convenient for turning over the undemolded mold and reducing labor intensity. After the preform in the mold is separated from the mold, the preform falls onto the support plate 15. When the support plate 15 is subjected to the pressure of the preform, the sleeve rod 13 slides downward in the sleeve 12. At this time, the spring 14 is in a compressed state. After the preform is taken out, the spring 14 drives the sleeve rod 13 and the support plate 15 to reset, and the mold The preform in the tool falls onto the support plate 15 after being separated from the mold. At this time, waste chips and impurities may be generated during the demoulding process, and the impurities on the support plate 15 are swept to the inner bottom wall of the base 2. When the wheel plate 19 is rotated, the single bidirectional screw 18 is driven to rotate, and the bidirectional screw 18 drives the single pulley 20 to rotate, and the pulley 20 drives the transmission belt 21 to run. At this time, the two bidirectional screws 18 can be driven by the pulley 20 to rotate at the same time and perform threaded motion with the arc plate 17, driving the arc plate 17 and the slide groove 16 to slide, so that the arc plates 17 are close to each other and can push the waste chips on the inner bottom wall of the base 2 to the cavity 22. When the waste chips and impurities are pushed to the cavity 22 by the arc plate 17, they fall into the collection box 23 and are collected by the collection box 23. Since the collection box 23 is threadedly connected to the base 2, the collection box 23 can be easily disassembled and the collected waste chips and impurities can be cleaned.
