Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and in particular relates to an injection mold for an automotive ABS sensor. Background Technology

[0002] In injection molding, traditional injection molds typically consist of a fixed rear mold base and a movable front mold base. The rear mold base is usually connected via a fixed structure of the injection molding machine, while the front mold base moves closer to or further away from the rear mold base via a specialized drive device. In the existing injection molding process for automotive ABS sensors, traditional injection molds typically have only one injection hole. This design leads to uneven material distribution during injection, affecting the yield and appearance quality of the finished product. Specifically, a single injection hole cannot ensure uniform material distribution during injection, resulting in over-insertion in some areas and under-insertion in others, thus reducing the consistency and quality of the finished product. To address these issues, this invention aims to improve the appearance quality and yield of injection molded products by establishing a novel injection mold design. Utility Model Content

[0003] The purpose of this invention is to provide a glue injection mold for vehicle ABS sensors, which aims to solve the technical problem that the single glue injection hole in the prior art cannot ensure the uniform distribution of material during the glue injection process. This results in some areas being over-injected while other areas are under-injected, thereby reducing the consistency and quality of the finished product.

[0004] To achieve the above objectives, this utility model provides a glue injection mold for an automotive ABS sensor, comprising a front mold base and a rear mold base, with the front mold base disposed on one side of the rear mold base. The rear mold base is connected to an injection molding machine, and the front mold base is connected to a driving device. The driving device is used to drive the front mold base towards or away from the rear mold base. The front mold base includes a front module, which has at least one front mold mounting hole at its end away from the rear mold base for connecting to the driving device. The front module has several front mold forming grooves at its end near the rear mold base, and also has several ejector pin holes, each ejector pin hole penetrating the front module and communicating with the front mold forming grooves, allowing ejector pins to pass through and eject the product from the front mold forming grooves. The rear mold base includes a rear module corresponding to the front module, which has at least one rear mold mounting hole at its end away from the front mold base for connecting to the injection molding machine. The rear module has several rear mold forming grooves at its end near the front mold base corresponding to the front mold forming grooves. The front mold forming grooves and the rear mold forming grooves cooperate to form a molding cavity. The rear module is also provided with several sets of through holes, which include several ring arrays of injection holes. Each injection hole penetrates the rear module, with one end connected to the injection molding equipment and the other end connected to the rear mold forming groove, to provide an injection channel for the forming cavity.

[0005] Furthermore, both the front mold forming groove and the rear mold forming groove are arranged in a ring shape. The front mold forming groove is provided with a limiting hole extending inward from its ring center, and the rear mold forming groove is provided with a limiting boss corresponding to the limiting hole extending outward from its ring center.

[0006] Furthermore, the rear module is also provided with several vent holes, each vent hole is located at the center of the through hole group, the vent hole passes through the rear module and one end passes through the limiting boss.

[0007] Furthermore, the front module has inwardly extending positioning grooves at all four corners, and the rear module has outward extending positioning bosses at all four corners corresponding to the positioning grooves. The positioning grooves and positioning bosses work together to position the front and rear modules.

[0008] Furthermore, the front module has four front mold mounting holes, arranged in a rectangular array on the front module. The rear module has four rear mold mounting holes, arranged in a rectangular array on the rear module.

[0009] Furthermore, the front module has four front mold forming grooves and four ejector pin holes, with each front mold forming groove and ejector pin hole arranged in a rectangular array on the front module. The rear module has four rear mold forming grooves and four sets of through holes, with each through hole set having eight injection holes, and each rear mold forming groove and each through hole set arranged in a rectangular array on the rear module.

[0010] The above-mentioned technical solutions of one or more of the injection molds for vehicle ABS sensors provided in this embodiment of the utility model have at least one of the following technical effects: When production is required, the drive equipment drives the front mold base closer to the rear mold base until the two molds abut against each other. Then, the injection molding equipment starts injection molding. The molten plastic enters the molding cavity formed by the front mold forming groove and the rear mold forming groove through each injection hole for injection molding. After injection molding is completed, the drive equipment drives the front mold base away from the rear mold base. At this time, the ejector pin moves in the ejector pin hole to push the molded product out of the front module, completing the demolding of the front module. Then, a robot arm is provided on the side to remove the molded product from the rear module. Injection into the molding cavity simultaneously through each injection hole ensures uniform material distribution during the injection process, improving the appearance quality of the injection molded product and the pass rate of the finished product.

[0024] In one embodiment of this utility model, reference is made to Figures 1-7As shown, a mold for a vehicle ABS sensor is provided, including a front mold base 100 and a rear mold base 200, with the front mold base 100 disposed on one side of the rear mold base 200. The rear mold base 200 is connected to an injection molding machine, and the front mold base 100 is connected to a driving machine. The driving machine is used to drive the front mold base 100 toward or away from the rear mold base 200. The front mold base 100 includes a front module 110, which has at least one front mold mounting hole 120 at the end away from the rear mold base 200 for connecting to the driving machine. The front module 110 has a plurality of front mold forming grooves 130 at the end near the rear mold base 200, and a plurality of ejector pin holes 140 on the front module 110. Each ejector pin hole 140 penetrates the front module 110 and communicates with the front mold forming grooves 130, allowing ejector pins to pass through and eject the product from the front mold forming grooves 130. The rear mold base 200 includes a rear module 210 corresponding to the front module 110. The rear module 210 has at least one rear mold mounting hole 220 at its end away from the front mold base 100, which is used to connect to an injection molding machine. The rear module 210 also has several rear mold forming grooves 230 at its end near the front mold base 100, corresponding to the front mold forming grooves 130. The front mold forming grooves 130 and the rear mold forming grooves 230 cooperate to form a molding cavity 300. The rear module 210 also has several sets of through-hole groups 240, each including several annularly arrayed injection holes 241. Each injection hole 241 penetrates the rear module 210, with one end connected to the injection molding machine and the other end communicating with the rear mold forming grooves 230, providing an injection channel for the molding cavity 300. In this embodiment, when production is required, the drive device drives the front mold base 100 closer to the rear mold base 200 until the two molds abut against each other. Then, the injection molding equipment begins injection molding. The molten plastic enters the molding cavity 300 formed by the front mold forming groove 130 and the rear mold forming groove 230 through the injection holes 241 for injection molding. After injection molding is completed, the drive device drives the front mold base 100 away from the rear mold base 200. At this time, the ejector pin moves in the ejector pin hole 140 to push the molded product out of the front module 110, completing the demolding of the front module 110. Subsequently, a robotic arm is provided to remove the molded product from the rear module 210. Simultaneous injection molding through the injection holes 241 into the molding cavity 300 ensures uniform material distribution during the injection process, improving the appearance quality of the injection molded product and the yield rate of the finished product.

[0025] Specifically, refer to Figures 1-7As shown, both the front mold forming groove 130 and the rear mold forming groove 230 are annularly arranged. A limiting hole 131 extends inward from the center of the front mold forming groove 130, and a limiting boss 231 corresponding to the limiting hole 131 extends outward from the center of the rear mold forming groove 230. In this embodiment, positioning is achieved through the cooperation between the limiting hole 131 and the limiting boss 231, allowing the front mold forming groove 130 and the rear mold forming groove 230 to stably close and form a molding cavity 300, thereby improving the appearance quality of the injection molded product and the yield rate of the finished product.

[0026] Specifically, refer to Figures 1-7 As shown, the rear module 210 is also provided with several vent holes 250, each vent hole 250 being located at the center of the through hole group 240. The vent holes 250 penetrate the rear module 210 and one end passes through the limiting boss 231. In this embodiment, when the limiting hole 131 and the limiting boss 231 are close to each other, the air in the limiting hole 131 is discharged through the vent holes 250, preventing it from being discharged from the side of the limiting hole 131 and affecting the quality of the injection molded product.

[0027] Specifically, refer to Figures 1-7 As shown, the front module 110 has inwardly extending positioning grooves 150 at each of its four corners, and the rear module 210 has outward extending positioning bosses 260 at each of its four corners corresponding to the positioning grooves 150. The positioning grooves 150 and positioning bosses 260 cooperate to position the front module 110 and the rear module 210. In this embodiment, through the cooperation of the positioning grooves 150 and positioning bosses 260, the closing positions of the front module 110 and the rear module 210 are kept consistent each time, so that the front mold forming groove 130 and the rear mold forming groove 230 can be stably closed to form the molding cavity 300, thereby improving the appearance quality of the injection molded product and the yield rate of the finished product.

[0028] Specifically, refer to Figures 1-7 As shown, the front module 110 has four front mold mounting holes 120, arranged in a rectangular array. The rear module 210 has four rear mold mounting holes 220, also arranged in a rectangular array. In this embodiment, the front and rear mold templates are mounted through the four front mold mounting holes 120 and the four rear mold mounting holes 220, making their positions more stable and improving the yield rate of the finished product.

[0029] Specifically, refer to Figures 1-7As shown, the front module 110 has four front mold forming grooves 130 and four ejector pin holes 140, arranged in a rectangular array. The rear module 210 has four rear mold forming grooves 230 and four sets of through holes 240, each set of through holes 240 having eight injection holes 241. In this embodiment, the four front mold forming grooves 130 and four rear mold forming grooves 230 can form four molding cavities 300. Correspondingly, more than four ejector pin holes 140 and more than four sets of through holes 240 are required, enabling the front module 110 and rear module 210 to complete four products in a single injection molding process, thus improving processing efficiency.

[0030] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
