Abstract
Description
Technical Field
[0001] This utility model specifically relates to a novel film manufacturing mold. Background Technology
[0002] The manufacturing process of the air spring's key component, the air spring's bladder, generally requires the overlapping and molding of film sheets. However, the main method for obtaining these film sheets is calendering. Calendering equipment is expensive, and each calendering operation requires at least 80 kg of rubber material. During the development of the air spring's rubber material formula, the formula needs continuous iteration and verification. Only 3-5 air spring products need to be verified during this iteration process, and only 5-10 kg of rubber material is needed for 3-5 air springs. Due to the limitations of the calendering process, continuously using calendering to verify the air spring's rubber material formula leads to significant waste, long development cycles, and high R&D costs. Therefore, we propose a new type of film sheet manufacturing mold. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-3 This utility model provides a technical solution: a novel film manufacturing mold, comprising:
[0024] Template 2;
[0025] The flow channel plate 1 is set on the upper template 2, and the flow channel plate 1 has a connection port 4 for connecting to an external injection vulcanizing machine, which facilitates the injection of rubber material.
[0026] The lower template 3 is set on the lower surface of the upper template 2, and the lower template 3 has a flow channel surface 301 to facilitate the formation of the required surface of the adhesive. The inner side of the flow channel surface 301 has a second flow-blocking step 302 to ensure the uniformity of the adhesive flow. The uniformity of the sheeting of adhesives with different hardness can be adjusted later by designing the size and position of the flow-blocking step.
[0027] The dispersion structure is set inside the upper template 2 to evenly disperse the injected adhesive material inside the flow channel surface 301, so as to better distribute the adhesive material evenly and ensure that the film thickness is consistent in the later production.
[0028] In this embodiment, preferably, the dispersion structure includes a first diversion groove 201, an injection port 202, a second diversion groove 204, and a diversion hole 205. The first diversion groove 201 and the second diversion groove 204 are symmetrically opened on the upper and lower surfaces of the middle part of the upper template 2. The diversion hole 205 penetrates the bottom surface of the first diversion groove 201 to communicate with the interior of the second diversion groove 204. An injection port 202 corresponding to the connection port 4 is opened in the middle of the inner side of the first diversion groove 201, which facilitates better dispersion of the adhesive material and evenly spread it on the inner side of the first flow channel surface 301.
[0029] In this embodiment, preferably, multiple diversion holes 205 are evenly distributed along one long side of the first diversion groove 201 to facilitate better uniform distribution of the adhesive.
[0030] In this embodiment, preferably, the depth of the first diversion groove 201 extending into the inner side of the upward template 2 is greater than the depth of the second diversion groove 204, which facilitates better initial diversion.
[0031] In this embodiment, preferably, the lower surface of the upper template 2 is provided with a first flow-blocking step 206, and the first flow-blocking step 206 and the second flow-blocking step 302 are staggered to facilitate better uniform flow of the adhesive.
[0032] In this embodiment, preferably, a sealing step 303 with reduced depth is provided at one end of the inner side of the flow channel surface 301 to ensure that the adhesive material flows only on the flow channel surface 301, ensuring pressure stability during the sheeting process and facilitating uniform sheeting.
[0033] In this embodiment, preferably, the lower template 3 has a warp opening 5 on its side wall. There are two warp openings 5 that are staggered, which makes it easier to separate the lower template 3 from the upper template 2 later.
[0034] In this embodiment, preferably, the upper surface of the upper template 2 is provided with a positioning pin 203, and the inner side of the flow channel plate 1 is provided with a positioning hole corresponding to the positioning pin 203, which facilitates accurate mold closing and improves the accuracy of connection.
[0035] The working principle and usage process of this utility model are as follows: During use, the connection port 4 is connected to the output port of the injection vulcanizing machine. The rubber material flows into the inner side of the first diversion groove 201 through the connection port 4 and the injection port 202. It is then diverted to the inner side of the diversion hole 205 through the first diversion groove 201. The rubber material is evenly spread on the inner side of the flow channel surface 301 through multiple diversion holes 205. The first flow-blocking step 206 and the second flow-blocking step 302 on the inner side of the flow channel surface 301 ensure uniform flow of the rubber sheet. In addition, the uniformity of the sheet extrusion of rubber materials with different hardness can be adjusted by designing the size and position of the flow-blocking steps. The inner side of the flow channel surface 301 is also provided with a sealing step 303 to ensure that the rubber material only flows on the flow channel surface 301, ensuring the pressure stability of the sheet extrusion process in the later stage and promoting uniform sheet extrusion. In addition, the lower mold plate 3 is provided with a mold opening 5 on both sides for easy disassembly by workers in the later stage.
