Description

Technical Field

[0001] The utility model belongs to the technical field of sealant preparation, and in particular relates to a sealant strip molding tool. Background Art

[0002] Silicone building sealant is a room temperature curing, UV resistant, high and low temperature resistant, corrosion resistant, and excellent adhesive sealing material. It is widely used in weatherproof sealing of various curtain walls, joint sealing between various materials such as metal, glass, and aluminum, and structural bonding and assembly between metal and glass of glass curtain walls.

[0003] When evaluating the performance of silicone building sealants, the usual simple and intuitive method is to pull the sealant strips, and the elasticity, strength and rebound ability of the strips can give you an intuitive impression of the sealant performance, especially at exhibitions, where visiting customers will pull the strips. However, when two-component silicone sealants are made, after the A component and the B component are mixed, the fluidity is better. After the round strips are applied, they will be deformed by gravity and become less regular. Summary of the invention

[0004] In view of the problem that the finished sealant becomes irregular due to its good fluidity during production, the utility model provides a rubber strip molding tool, and its technical solution is: one side of the box body is hinged with the upper cover plate, the other side of the box body is provided with a lower buckle, the opposite side of the upper cover plate connected to the box body is provided with an upper buckle, two top molds are provided inside the box body, and N middle molds are provided in the middle of the top molds; N≥0, N is an integer; one side of the top mold is provided with a casting groove with a semi-cylindrical structure; both sides of the middle mold are provided with casting grooves with a semi-cylindrical structure.

[0005] As a preferred solution, two slide grooves are provided on both sides of the box body, and scrapers are provided on the slide grooves on both sides, and the two scrapers are slidably connected to the slide grooves on both sides.

[0006] As a preferred embodiment, box positioning blocks are arranged at the four corners of the bottom of the box, mold positioning grooves are arranged at the four corners of the side without the casting groove of the top mold, mold positioning blocks are arranged at the four corners of the side with the casting groove of the top mold, mold positioning blocks are arranged at the four corners of one side of the middle mold, and mold positioning grooves are arranged at the four corners of the other side of the middle mold.

[0007] As a preferred solution, sealing strips are provided on both sides of the casting trough.

[0008] As a preferred solution, mold bolt holes are set at the two corners of the top mold without casting grooves, and side baffles are set on both sides of the top mold. The side baffles are connected to the mold bolt holes of the top mold by bolts through the baffle bolt holes.

[0009] As a preferred solution, a plurality of sealing rings are fixedly provided on one side of the side baffle, and the diameter of the sealing rings is adapted to the diameter of the casting trough.

[0010] As a preferred solution, the materials of the top mold and the middle mold are both anti-sticking materials, such as polytetrafluoroethylene.

[0011] The beneficial effects of the utility model are as follows: when the tooling is used to make the sealant strip, the sealant component A and the component B will not be deformed due to the good fluidity and gravity, and the tooling has good sealing performance and will not cause leakage of the sealant component, so that high-standard sealant strips can be made.
