Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an integrated mold for assembling automotive gear shift lever injection molding inserts. Background Technology

[0002] The background technology of the integrated injection molding and insert assembly mold for automotive gear shift levers lies in the contradiction between the limitations of traditional manufacturing processes and the demands of the modern automotive industry for efficient and high-precision production of parts. Traditional gear shift lever production typically employs a step-by-step processing and subsequent assembly method. This involves first manufacturing metal inserts (such as threaded sleeves, connecting pins, and reinforcing parts) separately through machining, stamping, or other processes, and then using injection molding to encapsulate the plastic body around the metal inserts to form the final product. This discrete production method has several inherent drawbacks: First, the production process is lengthy, requiring multiple machines, multiple molds, and multiple clamping and positioning operations, resulting in low production efficiency, long production cycles, and high labor and energy costs. Second, during the secondary injection molding process, the metal inserts need to be manually or robotically placed into the injection mold cavity. This positioning process is highly prone to errors, and the inserts may shift under the impact of the high-pressure molten metal, leading to quality problems such as uneven wall thickness, incomplete encapsulation, and out-of-tolerance dimensional accuracy, seriously affecting product consistency and reliability.

[0003] During the use of integrated molds, since the control lever needs to be injection molded, the mold needs to be firmly clamped and easily disassembled. Otherwise, it will affect the molding quality and production efficiency of the injection molded parts, and may even lead to product defects due to mold loosening or difficulty in disassembly. Utility Model Content

[0004] This utility model relates to an integrated mold for assembling an injection-molded insert for an automotive gear shift lever. The lower end of the injection mold is effectively constrained by two assembly molds, which are further restricted at their upper and lower ends by anti-detachment frames and anti-detachment bottom frames, forming a robust closed-loop lock in the vertical direction. Simultaneously, two clamping plates and two limiting plates are respectively installed on both sides of the upper end of the injection mold, applying a uniform and reliable clamping force. Through this multi-layered composite constraint and comprehensive limiting, the structural stability of the entire mold system is significantly enhanced during injection molding, effectively resisting the expansion force generated by the internal melt pressure. This ensures that the mold does not expand or deform during injection molding of the lever, guaranteeing product dimensional accuracy and molding quality.

[0005] In a first aspect, this utility model provides an integrated mold for assembling an injection-molded insert for an automotive gear shift lever, specifically comprising: an assembly mold; rectangular grooves at both ends of the two assembly molds, and two threaded grooves at each end of the rectangular grooves; an injection mold placed at the midpoint where the two assembly molds meet; fixing blocks fixedly installed at the rectangular grooves of the two assembly molds, with through threaded holes in the center of the fixing blocks; and through guide holes at the four corners of the two fixing blocks. Side plates are fixedly installed on both sides of the lower end of the two fixing blocks, and two through bolts are inserted into the side plates. Through threaded rods are rotatably inserted into the threaded holes of the two fixing blocks, and bearing rings are fixedly installed at the opposite ends of the two threaded rods. Clamping plates are slidably installed on the top of the two assembly molds, and anti-slip strips are evenly fixedly installed on the side walls of the clamping plates. Two slots are opened on the left side wall of the right clamping plate. Four guide rods are fixedly installed on the side walls of the clamping plates at both ends. The bottom of the clamping plates at both ends are respectively fixedly installed with mutually symmetrical sliders; the right side of the clamping plate at the left end is fixedly installed with mutually symmetrical extension plates, and the middle of the extension plates is provided with through fixing holes; through electric rods are respectively fixedly installed in the fixing holes of the two extension plates, and arc-shaped limiting plates are respectively fixedly installed at the opposite ends of the two electric rods.

[0006] Furthermore, the lower ends of the two assembly molds are equipped with anti-detachment bottom frames, and the upper side walls of the two assembly molds are fitted with mating anti-detachment frames, with through screws installed at the mating points of the two anti-detachment frames.

[0007] Furthermore, symmetrical upper hook blocks are fixedly installed on the upper ends of the two anti-detachment frames, parallel positioning plates are fixedly installed on the top ends of the two assembly molds, and parallel sliding grooves are opened on the upper ends of the two assembly molds.

[0008] Furthermore, four limiting grooves are provided on the left side of the assembly mold at the right end, and four limiting blocks are fixedly installed on the right side wall of the assembly mold at the left end. Symmetrical stabilizing grooves are provided on the side walls of the two assembly molds facing each other.

[0009] Furthermore, a sealing groove is provided on the left side of the injection mold at the right end, and a sealing strip is fixedly installed on the right side of the injection mold at the left end.

[0010] This utility model provides an integrated mold for assembling automotive gear shift lever injection molding inserts, which has the following advantages: In this utility model, the integrated mold is effectively constrained at its lower end by the stable clamping of two assembled molds. The upper and lower ends of these two assembled molds are further restricted by the anti-detachment frame and the anti-detachment bottom frame, respectively, thus forming a solid closed-loop lock in the vertical direction. At the same time, two clamping plates and two limiting plates are respectively set on both sides of the upper end of the injection mold, which together apply a uniform and reliable fixing clamping force. Through such multi-level composite constraint and comprehensive limitation, the structural stability of the entire mold system is significantly enhanced during the injection molding process. It can effectively resist the expansion force generated by the internal melt pressure, thereby ensuring that the control lever does not expand or deform during injection molding, and guaranteeing the product dimensional accuracy and molding quality.

[0011] By precisely aligning the molds at both ends, the sealing strip is first securely fastened into the sealing groove to ensure the seal at the interface. Then, the lower end of the injection mold is placed in the stabilizing groove for initial positioning. The anti-slip strips on the side wall of the clamping plate are used to effectively clamp both ends of the mold. Then, two electric rods are activated to push two arc-shaped limiting plates to apply uniform pressure to the mold from the front and back directions. This ensures that the overall structure of the mold is firm and reliable during high-pressure injection molding, effectively preventing any possible shaking or displacement, ensuring the dimensional accuracy and surface quality of the molded parts, and improving the stability and safety of the production process.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1 to 4 : This utility model proposes an integrated mold for assembling an injection-molded insert for an automotive gear shift lever, comprising: an assembly mold 1; two rectangular slots at both ends of the two assembly molds 1, and two threaded slots at each end of the rectangular slots; an injection mold 2 is placed at the midpoint where the two assembly molds 1 meet; injection material is injected from the upper end of the two mating injection molds 2; fixing blocks 3 are fixedly installed at the rectangular slots of the two assembly molds 1, and a through threaded hole is opened in the middle of the fixing blocks 3; through guide holes 301 are opened at the four corners of the two fixing blocks 3; side plates 302 are fixedly installed on both sides of the lower end of the two fixing blocks 3, and a threaded hole is inserted on the side plate 302. Two through bolts are used to rotate and insert the bolts on the side plate 302 into the threaded grooves of the assembly mold 1, thus fixing and restricting the side plate 302 and the fixing block 3. The fixing block 3 will not move when touched, allowing it to stably support the threaded rods 303. Control panels are fixedly installed on the opposite ends of the two threaded rods 303. Through threaded rods 303 are rotatably inserted into the threaded holes of the two fixing blocks 3. The threaded rods 303 are fixedly inserted into the inner ring of the bearing ring 304. A fastening ring is rotatably fitted onto the threaded rods 303. Bearing rings 304 are fixedly installed on the opposite ends of the two threaded rods 303. The control panels on the two threaded rods 303 are gripped. Rotating and moving in opposite directions, the bearing ring 304 on the threaded rod 303 pushes the two clamping plates 305 in opposite directions, using the anti-slip strips on the two clamping plates 305 to fix and clamp the two ends of the injection mold 2. Then, the two fastening rings on the two threaded rods 303 rotate and move in opposite directions, squeezing the side walls of the two fastening rings against the side walls of the fixing block 3, fixing and restricting the threaded rods 303 and the clamping plates 305. In this way, the injection mold 2 will not shift or open during injection molding. Remove the anti-detachment bottom frame 101 and anti-detachment frame 102, and then separate the two assembled molds 1. At this time, the two injection molds 2 can be taken out for easy disassembly. Take out the injection-molded control lever and bearing ring inside. A clamping plate 305 is fixedly connected to the outer ring of 304. The top of the two assembly molds 1 are respectively slidably mounted with clamping plates 305. When the clamping plates 305 at both ends move towards each other, they will stop moving when blocked by the positioning plate 104, so as to avoid the clamping plates 305 at both ends from excessively clamping the injection mold 2 and causing damage. Anti-slip strips are evenly fixedly installed on the side wall of the clamping plate 305. The anti-slip strips on the side wall of the clamping plate 305 are elastic. When the anti-slip strips on the clamping plate 305 clamp the injection mold 2, they will not damage the injection mold 2. Two slots are opened on the left side wall of the right clamping plate 305. Four guide rods 306 are fixedly installed on the side wall of the clamping plates 305 at both ends.The guide rod 306 slides through the guide hole 301. When the clamping plate 305 slides left and right, the guide rod 306 is restricted by the guide hole 301, and the clamping plate 305 can only slide left and right, preventing the clamping plate 305 from shifting or tilting when sliding left and right. Symmetrical sliders 307 are fixedly installed on the bottom of the clamping plates 305 at both ends. The sliders 307 are slidably installed in the slide groove 105. When the clamping plate 305 slides left and right, the sliders 307 are restricted by the slide groove 105, and the clamping plate 305 can only slide left and right, preventing the clamping plate 305 from shifting or tilting when sliding left and right. A corresponding slider is fixedly installed on the right side of the left clamping plate 305. Symmetrical extension plates 308 are provided, with inserts fixedly mounted on their side walls. These inserts are inserted into slots in the right-end clamping plate 305. A through-hole is formed in the center of each extension plate 308. Through-hole electric rods 309 are fixedly mounted in the fixing holes of both extension plates 308. Arc-shaped limiting plates 310 are fixedly mounted at opposite ends of the two electric rods 309. The two electric rods 309 push the two limiting plates 310 in opposite directions, and the concave surfaces of the limiting plates 310 securely clamp the front and rear ends of the injection mold 2, preventing displacement when the injection mold 2 is touched.

[0017] The two assembly molds 1 are equipped with anti-detachment bottom frames 101 at their lower ends. When the two assembly molds 1 are joined together, the limiting blocks 107 are inserted into the corresponding limiting grooves 106. After the two assembly molds 1 are joined together, their lower ends are installed in the anti-detachment bottom frames 101, which securely connect the lower ends of the two assembly molds 1. At this time, the lower ends of the two assembly molds 1 will not separate. The upper side walls of the two assembly molds 1 are fitted with mating anti-detachment frames 102, and the mating joints of the two anti-detachment frames 102 are fitted with through screws. The upper ends of the two anti-detachment frames 102 are respectively fixedly installed with symmetrical upper hook blocks 103. The upper ends of the upper hook blocks 103 hook onto the assembly molds 1 to prevent the anti-detachment frames 102 from sliding down, and the bottom of the upper ends of the upper hook blocks 103 hook onto the edge of the upper end of the assembly molds 1. Then, the screws at both ends are used to connect the two anti-detachment frames 102, thus securing the two anti-detachment frames together. The frame 102 is temporarily fixed and connected, and the two anti-detachment frames 102 will be fitted onto the upper ends of the two assembly molds 1 to fix and connect the upper ends of the two assembly molds 1. The top ends of the two assembly molds 1 are respectively fixedly installed with parallel positioning plates 104. The upper ends of the two assembly molds 1 are respectively opened with parallel sliding grooves 105. The left side of the right assembly mold 1 is opened with four limiting grooves 106. The right side wall of the left assembly mold 1 is fixedly installed with four limiting blocks 107. The side walls of the two assembly molds 1 facing one end are opened with symmetrical stabilizing grooves 108. The left side of the right injection mold 2 is opened with a sealing groove 201. The right side of the left injection mold 2 is fixedly installed with a sealing strip 202. When the two injection molds 2 are connected, the sealing strip 202 is inserted into the sealing groove 201, and then the lower end of the injection mold 2 is placed in the stabilizing groove 108.

[0018] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, side plates 302 are fixedly installed on both sides of the lower end of the two fixing blocks 3, and two through bolts are inserted on the side plates 302. After removing the side plates 302 and the bolts, the fixing blocks 3 are fixedly welded to the assembly mold 1 to stabilize and restrict the fixing blocks 3. In this way, the fixing blocks 3 will not move when touched, avoiding the bolts from loosening after long-term use and failing to stabilize the fixing blocks 3, while also saving on component costs.

[0019] The working principle of this embodiment is as follows: When using this integrated mold, the injection mold 2 is first placed in the stabilizing groove 108 where the two assembly molds 1 are joined. The sealing strip 202 on the mold and the sealing groove 201 cooperate to achieve a sealed connection, further ensuring positioning accuracy. When the two assembly molds 1 are joined, the limiting block 107 on the left assembly mold 1 is inserted into the limiting groove 106 on the right assembly mold 1, achieving initial positioning. Then, the lower ends of the two assembly molds 1 are installed in the anti-detachment bottom frame 101, and the upper ends are secured by two anti-detachment frames 102 and screws, ensuring that the two assembly molds 1 are firmly joined at both ends to prevent separation during injection molding. Then, by rotating the control disc on the two threaded rods 303, the threaded rods 303 push the bearing ring 304 and the clamping plate 305 connected to it to move towards the middle. The anti-slip strip on the side wall of the clamping plate 305 is used to support the injection mold. 2. The two ends are clamped and fixed. During the clamping process, the guide rod 306 slides in the guide hole 301 and the slider 307 moves in the slide groove 105 to ensure that the clamping plate 305 can only move horizontally and avoid tilting. After the clamping is in place, tighten the fastening ring on the threaded rod 303 so that it abuts against the side wall of the fixing block 3, thereby locking the clamping state and preventing the injection mold 2 from shifting during the injection process. In order to further enhance the stability of the injection mold 2, the electric rod 309 can be activated to push the two arc-shaped limiting plates 310 to clamp the injection mold 2 from the front and rear directions to ensure that it does not shake or shift during the high-pressure injection process. After the injection is completed, first release the electric rod 309 and the threaded rod 303 to release the clamping of the injection mold 2. Then disassemble the anti-detachment frame 102 and the anti-detachment bottom frame 101 to separate the two assembled molds 1. The injection mold 2 can then be taken out and opened to take out the molded car shift lever product inside.
