Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive strip preparation, and in particular to a mold structure for preparing arc-shaped adhesive strips. Background Technology
[0002] Traditional rubber strip production typically uses straight molds, extruding and shaping the strips in one piece before cooling to obtain a straight product. For curved strips, secondary hot bending or machining is usually required, resulting in complex processes, high costs, and poor curvature accuracy. Existing molding processes use fixed mold structures, making it impossible to directly produce products requiring curvature. When straight strips or secondary-processed curved strips are used with various curved glass surfaces, they fail to provide adequate sealing, waterproofing, and water-blocking properties. Furthermore, the rigid U-shaped grooves are prone to whitening and cracking, and the soft edges are easily deformed or wrinkled, limiting product design flexibility and failing to achieve the desired effect.

[0005] The beneficial effects of this utility model are: multiple mold blocks are detachably set on the substrate, which is conducive to arranging multiple mold blocks to form a variety of arc lines with different curvatures according to different processing requirements. This allows the semi-finished rubber strip to be pulled out of the mold blocks while cooling and shaping inside the multiple mold blocks with the curvature of the arc line. Compared with the prior art of secondary processing of straight products to obtain arc products, the technical solution of this utility model omits secondary hot bending and cooling processing, improves efficiency, saves processing costs, and also makes the obtained arc rubber strip have better sealing, waterproof and water-blocking effects.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the injection of external cooling water into the cooling space through the water inlet pipe, thereby allowing the semi-finished rubber strip, which has already become arc-shaped, to cool and solidify.
[0015] Furthermore, the cover plate is disposed on the top of the first mold block and / or the second mold block of the plurality of mold blocks.
