Description

Technical Field

[0001] This utility model relates to the field of mold technology for forming water-stop rubber pads, and in particular to a mold for forming water-stop rubber pads. Background Technology

[0002] In the traditional production process of waterproof rubber gaskets, the molding molds generally suffer from several technical bottlenecks, seriously affecting product quality and production efficiency. Firstly, demolding is a significant problem. The mold's forming surface design is simple, and the rubber easily sticks together under high temperature and pressure. Demolding requires external force, causing the gasket to deform, tear, or suffer surface damage, resulting in a high defect rate and accelerated mold wear. Secondly, poor venting leads to internal defects. Traditional molds lack a dedicated venting structure, preventing effective air removal from the rubber, easily forming bubbles, delamination, or looseness, reducing product density and mechanical strength, and affecting the waterproofing effect. Therefore, a new type of molding mold for waterproof rubber gaskets is needed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-5 A water-stop rubber pad forming mold includes an upper template 1 and a lower template 2. The bottom of the upper template 1 is in contact with the top of the lower template 2, and a forming device 3 is provided at the bottom of the upper template 1 and the top of the lower template 2. The forming device 3 realizes the action of extruding rubber sheet to form a water-stop rubber pad.

[0015] The molding device 3 includes molding bosses 4 set at the bottom of the upper template 1. Multiple molding bosses 4 are arranged in a rectangular array at the bottom of the upper template 1. A lace groove 5 is also provided at the bottom of the upper template 1, and multiple molding bosses 4 are located inside the lace groove 5.

[0016] Specifically, this is implemented by distributing multiple forming bosses 4 in a rectangular array, which ensures uniform extrusion of the rubber sheet in the mold, thereby making the shape of the water-stop pad more regular and ensuring the quality of the finished product. The setting of the lace groove 5 not only helps to improve the strength and durability of the mold, but also effectively helps to demold after the water-stop pad is formed, avoiding the problem of the pad being difficult to demold due to the bosses being too smooth during the molding process.

[0017] The molding device 3 also includes a molding groove 6 opened on the top of the lower template 2. Multiple molding grooves 6 are arranged in a rectangular array on the top of the lower template 2, and multiple molding bosses 4 are set one-to-one with multiple molding grooves 6. When the water-stop pad is molded, the molding bosses 4 are located inside the molding grooves 6.

[0018] Specifically, the forming bosses 4 and forming grooves 6 are set in a one-to-one correspondence to ensure a perfect connection between the upper template 1 and the lower template 2 during the forming process. This allows the rubber sheet to be subjected to uniform pressure during forming, avoiding irregular or incomplete forming caused by template misalignment.

[0019] The top of the lower template 2 is also provided with ventilation grooves 7. Multiple ventilation grooves 7 are arranged in a cross pattern, and multiple forming grooves 6 are located inside the rectangular frame formed by the cross arrangement of multiple ventilation grooves 7.

[0020] Specifically, the design of the venting groove 7 helps the mold effectively expel air from inside the rubber material during the molding process, preventing the formation of air bubbles and ensuring the density and structural stability of the water-stop pad. Through the cross-arranged venting grooves 7, the mold can provide sufficient airflow in multiple directions, thereby ensuring uniform pressure distribution during the molding process, reducing the occurrence of local air bubbles or voids, and further improving the molding quality of the water-stop pad.

[0021] Guide pillars 8 are fixedly installed at the bottom four corners of the upper template 1, and guide pillar holes 9 are opened at the top four corners of the lower template 2. Multiple guide pillars 8 are respectively set to correspond one-to-one with multiple guide pillar holes 9, and the arc surface of the guide pillar 8 is slidably inserted into the inner wall of the guide pillar hole 9.

[0022] Specifically, the guide pillars 8 and guide pillar holes 9 are configured in a one-to-one correspondence, ensuring that the upper mold plate 1 and the lower mold plate 2 can be precisely aligned during assembly, avoiding offset or misalignment between the mold plates. This precise alignment improves the positioning accuracy of the mold, thereby ensuring consistency during the molding process and high product quality.

[0023] Locking mounting holes 10 are provided on both sides of the lower template 2. During operation, the lower template 2 is locked and installed with the extrusion molding equipment through the locking mounting holes 10. The top of the upper template 1 is provided with a connecting mounting hole 11, which is threaded to the power drive end of the extrusion molding equipment.

[0024] Specifically, the lower template 2 is fixed to the locking device of the extrusion molding equipment through the locking mounting hole 10, ensuring that the template will not loosen or shift during the molding process, avoiding inconsistent molding or accidents caused by equipment instability, and enhancing operational safety; the upper template 1 is connected to the power drive end of the extrusion molding equipment through the connecting mounting hole 11, which simplifies the connection process between the mold and the equipment, reduces the complexity of docking operations, and improves production efficiency.

[0025] This waterproofing gasket molding die achieves efficient and high-precision rubber sheet extrusion molding through the optimized design of the upper and lower templates 2 and the molding device 3. The rectangular array of forming bosses 4 on the upper template 1 precisely aligns with the corresponding forming grooves 6 on the lower template 2, ensuring uniform pressure on the rubber sheet, resulting in a regular finished shape and stable quality. The decorative grooves 5 enhance the mold's strength and solve the demolding problem, preventing the gasket from sticking and being damaged. The cross-arranged ventilation grooves 7 effectively expel air from the rubber during molding, preventing bubble formation and improving the gasket's density and structural stability. The sliding insertion design of the four corner guide posts 8 and guide post holes 9 ensures precise positioning of the templates during mold closing, eliminating misalignment and ensuring consistent molding. The lower template 2 is fixed to the equipment via locking mounting holes 10, while the upper template 1 is connected to the power end via connecting mounting holes 11, ensuring convenient installation and stable operation, avoiding the risk of loosening or displacement, and guaranteeing operational safety and production efficiency.
