Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an easily detachable injection mold assembly. Background Technology

[0002] An injection mold is a specialized tool used in the injection molding process. It is usually made of high-strength materials such as steel. Its main function is to inject molten plastic material into the cavity of the mold in the injection molding machine. After cooling and solidification, a plastic product of a specific shape and size is obtained. An injection mold usually consists of two main parts: a moving mold and a fixed mold. During the injection process, these two parts close to form a cavity. After the injection is completed, they separate to remove the product.

[0003] Traditional injection molds are typically secured with a large number of bolts, making the process of changing the moving mold cumbersome. This requires disassembling multiple bolts and related components one by one, reducing overall production efficiency. Furthermore, it usually relies on manual removal of parts, which affects operational safety.

[0004] Therefore, those skilled in the art have provided an easily detachable injection mold assembly to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an easily disassembled injection mold assembly. Through the transmission of threaded rod and gear, the locking block is disengaged, realizing the rapid disassembly of the moving mold, simplifying the mold disassembly process, shortening downtime, and improving production efficiency. The servo motor and bidirectional threaded rod drive the linkage mechanism to automatically eject the finished product from the fixed mold slot, so that the operator does not need to manually pick up the part, thus improving the convenience of operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A detachable injection mold assembly includes a base and a connecting plate. The connecting plate has an installation mechanism on its outer wall, and the base has a lifting mechanism at its upper end. The installation mechanism includes a fixing plate. Cavities are formed on both sides of the inner wall of the fixing plate. Driven bevel gears are rotatably connected to the side of each cavity furthest from the center of the connecting plate. Threaded rods are fixedly connected to the side of each driven bevel gear closest to the center of the connecting plate. First threaded sleeves are fitted onto the outer walls of each threaded rod. Two connecting rods are fixedly connected to the side of each first threaded sleeve closest to the center of the connecting plate. A locking block is fixedly connected to the side of each adjacent connecting rod closest to the center of the connecting plate. Driven bevel gears are provided on both sides of the inner wall of the fixing plate. A groove is formed at the lower end of the fixing plate, and locking slots are formed on both sides of the connecting plate.

[0008] The above technical solution uses the cooperation of the threaded rod and gear transmission to drive the first threaded sleeve and connecting rod to move, which in turn drives the locking block to move and disengage from the locking slot, thus disassembling the moving mold without having to remove each bolt individually. This simplifies the mold disassembly process, effectively shortens equipment downtime, and improves overall production efficiency.

[0009] Furthermore, a fixed mold is fixedly connected to the upper end of the base. A slot is opened at the lower end of the inner wall of the fixed mold. A sliding groove is opened on the bottom surface of the slot. A bidirectional threaded rod is rotatably connected to one side of the inner wall of the sliding groove. Second threaded sleeves are fitted on both sides of the outer wall of the bidirectional threaded rod. Sliding blocks are fixedly connected to the upper ends of the two second threaded sleeves. First hinge blocks are hinged to the upper ends of the two sliding blocks. Hinge rods are hinged to the upper ends of the two first hinge blocks. Second hinge blocks are hinged to the upper ends of the two hinge rods. A top plate is hinged to the upper ends of the two second hinge blocks. A servo motor is fixedly connected to the other side of the inner wall of the sliding groove.

[0010] Through the above technical solution, the servo motor and the bidirectional threaded rod work together to drive the second threaded sleeve and the sliding block to move, which in turn drives the first hinge block to move. In conjunction with the hinge rod and the second hinge block, the top plate can be moved, which can push the injection molded mold out of the fixed mold slot. This eliminates the need for the operator to manually reach into the fixed mold slot to remove the part, thus improving the convenience and safety of the operation.

[0011] Furthermore, limit rods are fixedly connected to the four corners of the upper end of the base, and mounting plates are fixedly connected to the upper ends of the multiple limit rods. A cylinder is fixedly connected to the middle of the lower end of the mounting plate, and a moving mold is fixedly connected to the lower end of the connecting plate.

[0012] Through the above technical solution, the setting of the limit rod ensures that the moving mold maintains a high degree of alignment during the movement, avoiding deviation or shaking, and the cylinder has the characteristics of fast response speed and smooth operation.

[0013] Furthermore, the upper ends of the plurality of limiting rods all penetrate through the fixing plate to the outside of the fixing plate, and the cylinder output end is fixedly connected to the middle of the upper part of the fixing plate;

[0014] Through the above technical solution, the limiting rod provides vertical guidance for the moving mold, ensuring the repeatability and positioning accuracy of the mold closing and opening actions.

[0015] Furthermore, both of the aforementioned card blocks engage with the card slots, and both of the aforementioned card blocks slide on both sides of the groove;

[0016] Through the above technical solution, the locking design makes the fixing and loosening of the moving mold simple, and the groove provides guidance for the locking block, improving the accuracy of the locking block movement.

[0017] Furthermore, both of the driving bevel gears mesh with the driven bevel gear, and the upper ends of both driving bevel gears penetrate through the fixed plate to the outside of the fixed plate;

[0018] Through the above technical solutions, the gear meshing has the characteristics of compact structure and smooth transmission, and can quickly transmit the force of the rotating bevel gear to the threaded rod.

[0019] Furthermore, both of the sliding blocks slide on the inner wall of the groove;

[0020] With the above technical solution, the sliding block slides in the groove, ensuring that the top plate does not shake during the movement.

[0021] Furthermore, both second threaded sleeves are threadedly connected to the bidirectional threaded rod, and the output end of the servo motor is fixedly connected to the other side of the bidirectional threaded rod;

[0022] Through the above technical solution, a servo motor drives a bidirectional threaded rod to achieve precise control of the top plate position and speed.

The servo motor 210 drives the bidirectional threaded rod 203 to achieve precise control of the position and speed of the top plate 209.

[0043] Working principle: When using the machine, the user first rotates the driving bevel gear 110, which drives the driven bevel gear 103 and the threaded rod 104 to rotate through gear transmission. As the threaded rod 104 rotates, the first threaded sleeve 105 and the connecting rod 106 move accordingly, thereby moving the locking block 107 to disengage from the slot 109. This allows the connecting plate 7 and the moving mold 8 to be disassembled without removing each bolt individually, reducing downtime. During installation, simply place the connecting plate 7 into the groove 108, then rotate the driving bevel gear 110 in the opposite direction to move the threaded rod 104 and the locking block 107 to engage with the slot 109 for quick installation. After injection molding is completed, the machine can be started via an external controller. A servo motor 210 drives the bidirectional threaded rod 203 to rotate. As the bidirectional threaded rod 203 rotates, the second threaded sleeve 204 and the sliding block 205 move accordingly, which in turn drives the first hinge block 206 to move. Together with the hinge rod 207 and the second hinge block 208, they form a linkage mechanism, which drives the top plate 209 to move up and down, pushing the injection molded mold out of the fixed mold slot. This eliminates the need for the operator to manually reach into the fixed mold slot to retrieve the part, making it easy for the operator to remove the finished product. The upper rear part of the active bevel gear 110 is provided with a protrusion, and the lower end of the protrusion is provided with a spring. When in use, it is slid into the fixed plate 101. When not in use, the spring pushes the protrusion out of the fixed plate 101 to limit the active bevel gear 110 and prevent it from rotating.
