[0001] The utility model relates to the technical field of toilets, in particular to an auxiliary tooling for secondary injection molding of a seat ring and a toilet seat ring. Background Art

[0002] With the advancement of technology and people's increasing demands for quality of life, the functionality and comfort of smart toilets, as an important part of modern homes, have become the focus of market attention. Among them, the seat heating function is one of the key technologies to improve the user experience in winter. The built-in heating element effectively solves the problem of traditional toilet seats being too cold when used in cold seasons, significantly improving the comfort and convenience of use.

[0003] However, in the production process of smart toilet seats, especially in the secondary injection molding process after the upper and lower covers are formed, there is a technical problem that needs to be solved urgently. Since the exposed position and length of the heating element wire are often difficult to accurately control during assembly, this directly leads to the wire being easily squeezed or compressed during the secondary injection molding of the mold, resulting in poor production, which not only affects the product quality, but also increases the defective product rate in the production process and reduces the overall production efficiency. For this reason, we provide an auxiliary tooling for the secondary injection molding of the seat and a toilet seat to solve the above problem. Utility Model Content

[0045] The working process of this utility model is as follows: Figures 1 to 6As shown, first, overcome the elastic force of the spring 3 to move the left support member 1 and the right support member 2 closer to each other. Next, move them between the shaft holes on both sides of the seat ring, release the force acting on the left support member 1 and the right support member 2, and under the action of the elastic force of the spring 3, insert the connecting parts 6 of the left support member 1 and the right support member 2 into the shaft holes on both sides. At this time, limit the left support member 1 and the right support member 2 to prevent them from rotating, and the accommodating cavity 4 communicates with the avoiding opening 7. Next, the wire 11 passes through the avoiding opening 7 and is placed into the accommodating cavity 4, and the sliding cover 5 slides to close the radially opening provided in the accommodating cavity 4, thus completing the installation of the tooling main body. When the injection molding is completed, only need to operate the above steps in reverse to take out the tooling main body. The above operations need to be carried out every time injection molding is performed to prevent the wire 11 from being squeezed and damaged.
