Description

Technical Field

[0001] This utility model relates to the field of silicone product manufacturing technology, specifically to a silicone product demolding device. Background Technology

[0002] Silicone products are a common type of product in people's daily lives, and they are used in all aspects of people's lives. When producing silicone products, liquid silicone is generally injected into mold plates of different shapes, and then the liquid silicone is solidified under certain conditions and temperatures. Finally, the solidified silicone is taken out, thus obtaining silicone products of different shapes.

[0003] Chinese Patent No. CN220409370U discloses a silicone product demolding device, comprising a housing. A motor is fixedly connected to the inner front wall of the housing, and a rotating column is fixedly connected to the drive end of the motor. A driving bevel gear is fixedly connected to the outside of the rotating column. A sliding plate is slidably connected to the inner wall of the housing, and a threaded column is fixedly connected inside the sliding plate. A sleeve is threadedly connected to the outside of the threaded column, and a driven bevel gear is fixedly connected to the outside of the sleeve. A groove is provided on the inner top wall of the housing, and a top plate is slidably connected to the inner wall of the groove. This invention achieves mold demolding, facilitating the demolding of silicone products and improving production efficiency. It also achieves water cooling from the water tank and air cooling from the fan, reducing cooling time, lowering production costs, and improving production quality.

[0004] However, the above technical solution has the following shortcomings: During the demolding process of silicone products, the top plate structure can only achieve the initial ejection of the silicone product from the mold. The contact area between the top plate and the silicone product forms a large-area adhesion, and the top end face of the top plate is completely attached to the outer surface of the silicone product. Due to the high elasticity and surface adhesion of silicone material itself, after the top plate ejects the silicone product from the mold, the silicone product will continue to adhere to the surface of the top plate due to the adhesion and elastic deformation between it and the top plate, and cannot detach automatically. Manual intervention is required to peel the silicone product off the top plate by external force. This not only increases the manual operation steps but also increases the labor cost in the production process. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a silicone product demolding device.

[0006] The technical solution of this utility model: a silicone product demolding device, comprising:

This breaks the adhesion and clamping forces between the two, enabling the product to automatically detach from the demolding plate without manual intervention, thus reducing labor costs in the production process.

[0035] Example 3

Compared with Embodiment 2, this embodiment further discloses the structure of the separation mechanism. Each separation mechanism includes an installation cylinder 41, a sealing plug 42, and a reset assembly. The installation cylinder 41 is fixedly connected to the demolding template 6.
