Description

Technical Field

[0001] The utility model relates to the technical field of plastic product processing and demoulding, in particular to a water injection auxiliary demoulding device for plastic product processing and molding. Background Art

[0002] As we all know, the molding of plastic parts is inseparable from molds. After injection molding, plastic parts need to be demolded manually. Common demolding methods include automatic demolding, pneumatic demolding and mechanical demolding. The selection of demolding methods for plastic products is affected by factors such as material properties, product properties and size. When demolding barrel-shaped plastic parts, such as plastic barrels, a suction cup demolding device is used to assist in demolding. When the suction cup demolding device is working, the adsorption surface and the blowing hole of the suction cup are easily contaminated by dust and other substances in the environment, resulting in clogging of the adsorption hole, thereby reducing the adsorption effect of the suction cup, causing the plastic barrel to fall and be damaged. In addition, during long-term use, components such as the adsorption surface and the blowing hole are damaged, and the sealing performance inside the suction cup will decrease, resulting in a decrease in the vacuum degree, which will cause the plastic barrel to fall and be damaged. This requires staff to frequently clean and replace the suction cup, which increases the workload and processing costs of the staff and reduces the overall demolding efficiency. Therefore, a water injection auxiliary demolding device for plastic product processing and molding is proposed to address the above problems. Utility Model Content
