Description

TECHNICAL FIELD

[0001] The utility model relates to the mould field, especially, relate to a kind of composite coating nitrile glove mould. BACKGROUND

[0002] As a widely used personal protective equipment, rubber gloves usually include the following key steps in its production process: hand mold dipping, vulcanization setting and final demolding. In these steps, the demolding efficiency and vulcanization efficiency of gloves are important factors affecting the overall production efficiency.

[0003] To solve the problem of difficult demolding and low efficiency of traditional glove mold, the utility model patent of China authorized publication No.CN219618319U discloses a rubber glove mold convenient for demolding. The mold skillfully designs an internal communication gas delivery cavity, a gas delivery cavity and a shuttle-shaped sealing cavity extending to the fingertips. In the demolding process, by delivering gas into the mold, the formed rubber glove is separated from the mold surface at the key parts such as the fingertips by using the gas pressure, so as to realize the rapid separation of the glove and the mold, and significantly improve the convenience and efficiency of the demolding operation.

[0004] However, in the production process of rubber gloves, the glove mold with rubber after dipping must first enter the oven to vulcanize under specific temperature and time conditions to give the rubber the required physical and chemical properties. After vulcanization, demolding operation can be carried out. In order to improve the production efficiency of the vulcanization process, the usual practice is to fix a plurality of glove molds on a specially designed support frame, and then push the entire support frame into the oven through a sliding rail or other conveying device for centralized vulcanization.

[0005] Under this background, the rubber glove mold disclosed in the aforementioned CN219618319U patent is inconvenient to operate in terms of connection and fixation with the support frame. Specifically, it is designed to fix a single glove mold on the support frame by four fastening screws. This means that the operator needs to tighten or loosen up to four fastening screws for each glove mold one by one before each time the mold is loaded onto the support frame and sent into the oven for vulcanization, and after vulcanization is completed, the mold is removed from the support frame for demolding. When a large number of molds need to be handled, this repetitive screw tightening and loosening operation not only consumes time and effort, significantly increases the labor intensity of workers, but also reduces the efficiency of mold loading and unloading, thereby affecting the turnover efficiency of the entire vulcanization process and even the production line.

[0006] Therefore, how to further optimize the connection between the glove mold and the vulcanization support frame, simplify the loading and unloading operation, and improve the vulcanization production efficiency under the premise of easy demolding of the glove mold is a technical problem that needs to be solved in the current field.
