Description

TECHNICAL FIELD

[0001] The utility model relates to a demolding tool technical field, concretely relates to a pneumatic demolding tool for rubber sleeve processing. BACKGROUND

[0002] Rubber sleeve has wide application in industrial production. In recent years, when carrying out production-study-research with enterprises, it is found that enterprises mainly adopt manual demolding for the demolding process of rubber sleeve. Since rubber sleeve is attached to a core mold (such as shown in the figure) and the length of rubber sleeve is relatively long, it leads to time-consuming and laborious manual demolding. The enterprises require corresponding improvement of the demolding process to facilitate rapid demolding. Figure 6

[0003] Through consulting relevant information, it is known that the prior art has carried out relevant research on the demolding of rubber sleeve. For example, a rubber cylinder demolding device is disclosed in Chinese patent (authorized publication number: CN2340598Y), which mainly adopts the combined action of water pressure and counterweight to pull down the rubber cylinder from the core mold. For another example, a long tube rubber part demolding mechanism is disclosed in Chinese patent (authorized publication number: CN220883252U), which realizes the clamping and unclamping of the movable mold body, the fixed mold body and the front mold position on one side through single driving, does not need to use a large injection molding machine, facilitates production and mold opening work on a small machine table, and facilitates automatic and rapid demolding of the long tube rubber part from the mold core after unclamping. Through analysis of the prior art, although the problems of demolding are solved to a certain extent, it is not suitable for the enterprise. The enterprise seeks to design a low-cost, convenient-to-operate and rapid demolding auxiliary demolding tool for demolding in cooperation with the core mold without changing the existing production process. Therefore, it is necessary to design a practical demolding tool that is more matched to the enterprise in combination with the actual situation of the enterprise.
