Fomtec applies for the patent of a pneumatic anti-sticking clamping device for an injection molding machine, avoiding damage to the finished round tube during the clamping process.
According to a report in the financial sector on July 12, 2025, information from the State Intellectual Property Office showed that Fomtec Plastic Machinery (Guangzhou) Co., Ltd. applied for a patent called "A pneumatic anti-stick mold clamping device for an injection molding machine", publication number CN120287508A, and application date May 2025.
The patent abstract shows that the present invention relates to a pneumatic anti-sticky mold clamping device for an injection molding machine, belonging to the technical field of injection molding machines, including a clamping mechanism and a separation mechanism.
the clamping mechanism is set in the lower mold for clamping the finished round tube product of injection molding, and the separation mechanism is set in the clamping surface of the clamping mechanism on the finished round tube product, the separation mechanism is used for rolling contact with the finished round tube product, and the separation mechanism is used for rolling contact with the finished round tube product;
the separation mechanism includes a connecting shaft and a number of rotating balls; the connecting shaft is fixedly disposed in the clamping mechanism, a number of rotating balls are rotationally connected with the connecting shaft, the rotating balls protrude from the clamping surface of the clamping mechanism, and the rotating balls are rotationally contacted with the finished round tube product; the rotating balls of the present application can not only realize rotational contact with the finished round tube product, reduce friction with the finished round tube product, and avoid damaging the finished round tube product during the clamping process, but also through the adsorption slot and the finished round tube product.
The adsorption effect can also prevent the adhesion effect between the finished round tube and the upper mold through the adsorption slot and the finished round tube in the process of rotation.
