Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for plastic products. Background Technology

[0002] Injection molds for plastic products, as key tools in the injection molding process, are generally composed of two or more mold components working together. In the injection molding production process, plastic granules are heated to a molten state using specialized equipment and then precisely injected into the cavity of the mold. After sufficient cooling and solidification within the cavity, the resulting plastic product conforms to the design requirements. Injection molds play a crucial role in the large-scale production of plastic products; their performance and quality directly affect the final product quality, overall production efficiency, and manufacturing cost control.

[0003] For example, the utility model patent with authorization announcement number CN222201488U discloses a plastic product injection mold. Its working principle is as follows: "When the device is needed, the user first selects a suitable first injection block and second injection block according to the requirements of the product to be processed. Then, they are respectively snapped onto the first and second fixed frames, and fixed into the slot by snapping the threaded rod. Finally, the fastening nut is rotated to securely limit and fix the first and second injection blocks onto the first and second fixed frames." However, this injection block is inconvenient to disassemble and assemble. When the injection block needs to be disassembled or reinstalled, the operator has to unscrew multiple fastening nuts distributed on both sides of the first and second fixed frames one by one. This process not only consumes a lot of time and effort, but also may result in the loss of nuts due to improper operation during frequent operation, which will have a certain impact on the normal use of the injection block. The overall operation process is still quite troublesome. Utility Model Content

With the setting of the driving mechanism, the user only needs to rotate the rotating blocks located on both sides of the fixed or movable frame to fix or release the corresponding injection block. No complicated operation is required, which improves the flexibility of the mold and can adapt to the production needs of different plastic products.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a plastic product injection mold, including a base, a movable frame, a fixed frame, a movable injection block, a fixed injection block, a cylinder, a slide table, and a slide rail. The slide rail is fixedly disposed on the surface of the base, the fixed frame is fixedly disposed on the upper end of the slide rail, the movable frame is slidably engaged with the slide rail via a slide table fixedly disposed at its lower end, the fixed injection block is slidably disposed inside the fixed frame, the movable injection block is slidably disposed inside the movable frame, a cylinder is installed at one end of the base, and one end of the cylinder is fixedly connected to the movable frame. A driving mechanism is rotatably disposed inside the grooves on both sides of the fixed frame and the movable frame. The driving mechanism has multiple movable parts, and a locking block is fixedly connected to the end face of each movable part. Multiple through holes are opened inside the grooves on both sides of the fixed frame and the movable frame, and multiple locking slots are opened on both sides of the movable injection block and the fixed injection block. The locking block passes through the through holes and extends into the locking slots.

[0006] As a preferred embodiment of this utility model, one end of the snap-fit ​​block is provided with an angle, and a stop block is fixedly connected inside the snap-fit ​​groove.

[0007] As a preferred embodiment of this utility model, the driving mechanism includes a rotating rod, a rotating block, a first meshing wheel, a fastening screw, a second meshing wheel, and a slider. A rotating rod is rotatably mounted inside the grooves on both sides of the fixed frame and the moving frame. A rotating block is fixedly connected to the surface of the rotating rod. Multiple first meshing wheels are fixedly connected to the surface of the rotating rod. Multiple fastening screws are rotatably mounted inside the grooves on both sides of the fixed frame and the moving frame. A second meshing wheel is fixedly connected to one end of each fastening screw, and the second meshing wheel meshes with the first meshing wheel. A slider is threadedly connected to the surface of the fastening screw, and the slider slidably engages with the groove.

[0008] As a preferred embodiment of this utility model, the base is internally fixedly connected with multiple fixing rods, and one end of the movable frame is elastically provided with an ejection mechanism.

[0009] As a preferred embodiment of this utility model, the ejection mechanism includes a fixed ring, a push rod, a top plate, a spring, a fixed plate, and a top hole.

One end of the spring is fixedly connected to the fixed ring, and the other end of the spring is fixedly connected to the top plate.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0011] Rotating the drive mechanism causes multiple moving parts to move synchronously, displacing multiple locking blocks simultaneously and releasing them from the locking slots. This quickly releases the constraints on the fixed and moving injection blocks, making operation convenient and shortening disassembly and replacement time. Reversing the rotation of the drive mechanism inserts the locking blocks into the locking slots, and their inclined ends press against the inclined ends of the abutment blocks, generating force into the fixed or moving frames, firmly locking the injection blocks in place. This ensures stable and precise installation, guaranteeing injection quality. Users only need to rotate the rotating blocks located on both sides of the fixed or moving frames to fix or release the corresponding injection blocks without complicated operations, improving the flexibility of mold use and adapting to the production needs of different plastic products.

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a plastic product injection mold, including a base 1, a movable frame 2, a fixed frame 3, a movable injection block 4, a fixed injection block 5, a cylinder 13, a slide table 7, and a slide rail 8. The slide rail 8 is fixedly disposed on the surface of the base 1, the fixed frame 3 is fixedly disposed on the upper end of the slide rail 8, the movable frame 2 is slidably engaged with the slide rail 8 through the slide table 7 fixedly disposed at its lower end, the fixed injection block 5 is slidably disposed inside the fixed frame 3, the movable injection block 4 is slidably disposed inside the movable frame 2, and one end of the base 1 is equipped with... There is a cylinder 13, one end of which is fixedly connected to the movable frame 2. Both sides of the fixed frame 3 and the movable frame 2 are rotatably equipped with a drive mechanism 6. The drive mechanism 6 has multiple moving parts, and each moving part is fixedly connected to a snap-fit ​​block 10 at its end face. Both sides of the fixed frame 3 and the movable frame 2 are provided with multiple through holes 11. Both sides of the movable injection block 4 and the fixed injection block 5 are provided with multiple snap-fit ​​grooves 12. The snap-fit ​​block 10 passes through the through hole 11 and extends into the interior of the snap-fit ​​groove 12.

[0021] When the user needs to disassemble and replace the fixed injection block 5 and the movable injection block 4, they only need to rotate the rotating part of the drive mechanism 6. This operation will cause multiple moving parts of the drive mechanism 6 to move synchronously, thereby causing multiple locking blocks 10 to displace simultaneously. As the locking blocks 10 disengage from the locking groove 12, the constraints on the fixed injection block 5 and the movable injection block 4 are released. The user only needs to rotate the drive mechanism 6 located on both sides of the fixed injection block 5 or the movable injection block 4 to easily release the constraints on the corresponding injection block. The entire disassembly and replacement process is convenient and efficient, greatly improving the flexibility of mold use and production efficiency.

[0022] like Figure 3 and Figure 4 As shown, one end of the snap-fit ​​block 10 is provided with an angle, and the snap-fit ​​groove 12 is fixedly connected to the abutment block 14.

[0023] When it is necessary to install the fixed injection block 5 or the movable injection block 4, the user rotates the rotating part of the drive mechanism 6 in the opposite direction, so that the multiple moving parts of the drive mechanism 6 move synchronously and drive the multiple snap-fit ​​blocks 10 to insert into the snap-fit ​​groove 12. The inclined end of the snap-fit ​​block 10 presses against the inclined end of the abutment block 14, thereby generating a force on the fixed injection block 5 or the movable injection block 4 into the fixed frame 3 or the movable frame 2, so that the fixed injection block 5 or the movable injection block 4 is firmly locked inside the fixed frame 3 or the movable frame 2.

[0024] like Figure 3 As shown, the drive mechanism 6 includes a rotating rod 61, a rotating block 62, a first meshing wheel 63, a fastening screw 64, a second meshing wheel 65, and a slider 66. The rotating rod 61 is rotatably arranged inside the grooves on both sides of the fixed frame 3 and the movable frame 2. The rotating block 62 is fixedly connected to the surface of the rotating rod 61. Multiple first meshing wheels 63 are fixedly connected to the surface of the rotating rod 61. Multiple fastening screws 64 are rotatably arranged inside the grooves on both sides of the fixed frame 3 and the movable frame 2. A second meshing wheel 65 is fixedly connected to one end of the fastening screw 64. The second meshing wheel 65 meshes with the first meshing wheel 63. The slider 66 is threadedly connected to the surface of the fastening screw 64. The slider 66 is slidably engaged with the groove.

[0025] The user rotates the rotating block 62, which in turn rotates the rotating rod 61, causing multiple meshing wheels 63 to rotate. The rotation of these wheels causes multiple meshing wheels 65 to rotate, which in turn causes the fastening screw 64 to rotate. This rotation of the screw causes the slider 66 to slide, which in turn causes the locking block 10 to move, allowing it to insert into or disengage from the locking groove 12. Since the user only needs to rotate the rotating blocks 62 located on either side of the fixed injection block 5 or the movable injection block 4 to fix or release it, the operation is quite convenient.

[0026] like Figure 5 As shown, the base 1 has multiple fixed rods 15 fixedly connected inside, and the movable frame 2 has an ejection mechanism 9 elastically provided at one end.

[0027] When the mold opening operation is performed, the user activates the cylinder 13, which causes the telescopic end of the cylinder 13 to move, thereby driving the moving frame 2 to move. The moving frame 2 slides on the upper end of the slide rail 8 via the slide table 7, thereby causing the moving injection block 4 to detach from the fixed injection block 5. When the ejection mechanism 9 contacts the fixed rod 15, the fixed rod 15 presses the elastic end of the ejection mechanism 9, thereby ejecting the parts inside the moving injection block 4.

[0028] like Figure 6As shown, the ejection mechanism 9 includes a fixed ring 91, an ejector rod 92, a top plate 93, a spring 94, a fixed plate 95, and a top hole 96. The surface of the moving end of the cylinder 13 is fixedly connected to the fixed plate 95, and the surface of the fixed plate 95 is provided with multiple top holes 96. One end of the moving frame 2 is fixedly connected to multiple fixed rings 91. The ejector rod 92 is slidably arranged inside the fixed ring 91. The ejector rod 92 passes through the moving frame 2 and is slidably connected to the moving injection block 4. One end of the ejector rod 92 is fixedly connected to the top plate 93. The surface of the ejector rod 92 is wound with a spring 94. One end of the spring 94 is fixedly connected to the fixed ring 91, and the other end of the spring 94 is fixedly connected to the top plate 93.

[0029] In the initial state, due to the compression of the fixed plate 95, the spring 94 is in a compressed state, which makes the ejector rod 92 stable inside the movable injection block 4. When the cylinder 13 retracts, the ejector mechanism 9 moves closer to the fixed rod 15, which causes the fixed rod 15 to pass through the top hole 96 and press against the top plate 93, thereby driving the ejector rod 92 to slide inside the movable injection block 4, so that the part can be ejected.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
