DETAILED DESCRIPTION

[0014] To make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

[0015] Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present disclosure.

[0016] refer to Figure 1-3 .

[0017] The utility model provides a sealing cap forming jig, comprising an upper jig 1 and a lower jig 2, wherein the upper jig 1 comprises a first cup body 10 and an annular upper jig plate 11 arranged on the top circumference of the first cup body 10, and the lower jig 2 comprises a second cup body 20 and an annular lower jig plate 21 arranged on the top circumference of the second cup body 20, wherein the top edge of the annular lower jig plate 21 is provided with a plurality of ear plates 22 in an annular array, and an undercut 220 is arranged on the inner side of the ear plate 22, and the annular upper jig plate 21 is provided with a plurality of ear plates 22 in an annular array. There are snap-fitting grooves 110 arranged corresponding to the ear plates 22 on the edge of 11, and the snap-fitting grooves 110 are matched with the ear plates 22; when the upper jig 1 and the lower jig 2 are combined, the first cup body 10, the annular upper jig plate 11, the second cup body 20, and the annular lower jig plate 21 surround and form the cavity 3, the ear plate 22 is located on the snap-fitting grooves 110 and the undercuts 220 are engaged with the top of the annular upper jig plate 11, and a plurality of top material grooves 111 are distributed through the annular upper jig plate 11.

[0018] Its working principle is that the cavity 3 is set to a shape matching the sealing extrusion structure. After a certain amount of sealing extrusion is injected into the second cup body 20, the upper fixture 1 and the lower fixture 2 are combined. When assembling, each ear plate 22 is aligned with each snap-fit ​​groove 110 and assembled until the undercut 220 is buckled on the top of the annular upper fixture plate 11, so that the sealing extrusion fills the entire cavity 3, avoiding the movement of the upper fixture 1 and the lower fixture 2 during the sealing extrusion molding process, improving the molding quality, and after the sealing extrusion is heated and molded, force can be applied to the top of the annular lower fixture plate 21 through the top material groove 111 to achieve the separation of the second cup body 20 and the first cup body 10, so as to facilitate the sealing extrusion to be made into a structural member suitable for a screw nut, and the use amount of the sealing extrusion can be controlled, the use cost can be controlled, and the aesthetics can be improved.

[0019] Based on the above embodiment, a through groove 112 adjacent to the ear plate 22 is provided on the annular lower fixture plate 21, which can increase the elasticity and range of motion of the ear plate 22, making it easier for the undercut 220 to be engaged with or disengaged from the annular upper fixture plate 11.

[0020] Based on the above embodiment, a avoiding inclined surface 110a is provided on the side of the locking groove 110. When the upper fixture 1 and the lower fixture 2 are combined or disengaged, the avoiding inclined surface 110a can avoid and guide the undercut 220, thereby improving the smoothness of the combination or disengagement operation.

[0021] Based on the above embodiment, a plurality of ears 113 extending from the edge of the annular upper jig plate 11 are evenly distributed on the outer edge of the annular upper jig plate 11, and the ears 113 exceed the edge of the annular lower jig plate 21. When the upper jig 1 and the lower jig 2 are combined or separated, the ears 113 of the upper jig 1 can be grasped to press or lift the upper jig 1, so as to facilitate the application of force.

[0022] Based on the above embodiments, the upper fixture 1 and the lower fixture 2 are both made of POM plastic. POM plastic has the characteristics of high hardness, high rigidity and high wear resistance, which can solve the problem of sealant sticking to the mold, causing low demoulding efficiency and cracking, and can improve production efficiency.

[0023] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
