Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a submerged adhesive structure that improves the mirror-like appearance of a product. Background Technology

[0002] Mold injection molded products such as Figure 1 As shown, the green area represents a mirror finish, which exhibits high adsorption resistance during molding, easily leading to sticking to the mold and poor deformation. Due to the product's shape / structure limitations, a submerged gate is required for molding. Figure 2 As shown, the submersible gate is usually plagued by material debris. After the sprue is ejected, the bending area deforms and the sprue is demolded. This structure leaves material debris on the mold surface, requiring the mold surface to be cleaned periodically during production, which increases labor and time costs. If the above problems can be solved without affecting the appearance and function, the production cost will be greatly reduced.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a submerged adhesive structure to improve the mirror-like appearance of the product. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a submerged rubber structure that improves the mirror appearance of the product, increases the gripping force of the structural surface, increases the tensile force of the male mold structural surface, makes the sprue in the bending area more easily deformable, effectively positions the material during ejection, and reduces the sprue and mold core friction that generates sprue debris.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: A submerged adhesive structure for improving the mirror-like appearance of a product is provided. This submerged adhesive structure includes a gating system and several products connected to the gating system. The connection between the gating system and the products uses a submerged adhesive structure. The submerged adhesive structure includes a submerged sprue and an adhesive inlet. The head of the submerged sprue is connected to the gating system. The submerged sprue is inclined downwards towards the cavity where the product is located. The tail of the submerged sprue is connected to the bottom surface of the product through the adhesive inlet. An arc-shaped groove is formed at the lower end of the head of the submerged sprue, and the area where the arc-shaped groove is located is a bending area. The bending area is enlarged. A positioning head is extended downwards at the lower end of the gating system, opposite to the push rod. The positioning head is lengthened. The tail of the submerged sprue is the gate position.

[0006] Preferably, the arc-shaped groove is enlarged, and a transition slope is provided at the connection between the arc-shaped groove and the submersible channel to facilitate material removal and bending.

[0007] Preferably, the inner wall array of the product is provided with a plurality of adhesive-skimming areas for increasing the grip of the structural surface, and the inner wall of the product is the structural surface.

[0008] Preferably, the area where the glue is stolen is provided with an inwardly inclined demolding pin, which is located inside the male mold, and the inclined pin is provided with a barb that cooperates with the area where the glue is stolen.

[0009] Preferably, the sides and top of the glue-stealing area smoothly transition to the inner wall of the product, and the bottom surface of the glue-stealing area is provided with a sharp angled barb that cooperates with the barb, and the sharp angled barb is a flat surface without an angle.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The product's inner wall has several areas designed to reduce adhesive loss, thereby increasing the grip of the structural surfaces.

[0012] The design of the extended positioning sprue and the enlarged bending area make the sprue in the bending area easier to deform. After ejection, the positioning sprue is 3-4mm inside the mold core, which effectively positions the sprue and reduces the friction between the gate and the mold core opening to generate sprue debris during ejection.

[0013] Adding barbs to the slanted pin increases the tensile strength of the mold structure surface, and the inward slanted demolding of the slanted pin has less impact on the product.

[0014] The structural surface where the glue is stolen needs to be reinforced with a sharp angle by adding a barb, making it a flat surface without angles. Attached Figure Description

During ejection, it is effectively positioned and reduces the friction between the gate and the mold core to generate slag. After ejection, the positioning head 11 is 3-4mm inside the mold core. The increased bending area reduces the friction of the gate.
