[0040] Example

[0041] like Figure 1-6 As shown, the present invention proposes a mold for injection molding of plastic products, including a fixed mold base plate 1 and a movable mold base plate 3. The top of the fixed mold base plate 1 is fixedly provided with multiple guide rods 2. The movable mold base plate 3 is movably connected to the guide rods 2. The upper part of the movable mold base plate 3 is provided with a cylinder 4 for driving. The top of the fixed mold base plate 1 is provided with a fixed template 6 for introducing molten material. The bottom of the movable mold base plate 3 is provided with a movable template 5 for mold closing and opening. The fixed mold base plate 1 and the movable mold base plate 3 are each provided with two sliding grooves 7 on their adjacent sides. The sliding grooves 7 are provided with positioning components 9 for fixing. The fixed template 6 and the movable template 5 are each provided with a horizontal plate 10 on both sides.

[0042] The positioning assembly 9 includes a slider 901 for installation. The slider 901 contains two positioning rods 904 for positioning. Both sides of the slider 901 have receiving holes 902, and a spring 903 is fixedly installed within each receiving hole 902. The other end of the spring 903 is fixedly connected to the positioning rod 904. The positioning rod 904 and the receiving hole 902 are movably connected. A limiting block is fixedly installed at the bottom of the slider 901. The bottom of the slide groove 7 has a limiting groove, which is movably connected to the limiting block. Multiple positioning holes 8 are provided on the inner walls of both sides of the slide groove 7. The positioning holes 8 are adapted to the positioning rods 904. The front of the slider 901 has two through slots 905. A pull plate 906 is movably installed within each through slot 905. One end of the pull plate 906 passes through the through slot 905 and is fixedly fitted with a pull handle. The other end of the pull plate 906 is connected to the positioning rod 904. 04 Fixed connection: The top of the slider 901 is fixedly provided with a support frame 907 for installation. One end of the support frame 907 is provided with a transverse pressure plate 908 for positioning. The transverse pressure plate 908 fits against the side of the template to achieve transverse positioning of the template. The bottom of the support frame 907 is provided with a longitudinal pressure plate 910 for positioning. The longitudinal pressure plate 910 fits against the horizontal plate 10 to achieve longitudinal positioning of the template. The top of the longitudinal pressure plate 910 is rotatably provided with a threaded rod 909. The threaded rod 909 and the support frame 907 are movably connected. The top of the threaded rod 909 is fixedly provided with a turntable 912. The outside of the turntable 912 is provided with multiple rectangular plates 913. The top of the horizontal plate 10 is provided with two insertion holes 11. The bottom of the longitudinal pressure plate 910 is fixedly provided with two insertion rods 911. The insertion rods 911 and the insertion holes 11 are compatible.

[0043] The top of the support frame 907 is fixedly provided with a limiting structure 12. The limiting structure 12 includes a vertical plate 121 for installation. A pull rod 122 is movably provided on the vertical plate 121. One end of the pull rod 122 is fixedly provided with an insert plate 123. A spring 124 is sleeved on the pull rod 122. The limiting structure 12 can realize the positioning of the turntable 912 and prevent the longitudinal pressure plate 910 from separating from the horizontal plate 10 due to frequent vibration during processing, which would cause the template to loosen.

[0044] In this embodiment, the bottom of the moving template 5 and the top of the fixed template 6 are respectively provided with matching cores and cavities. When it is necessary to replace the fixed template 6 and the moving template 5, first pull the pull rod 122 to one side. The pull rod 122 drives the insert plate 123 to disengage from the adjacent rectangular plate 913. Then, rotate the threaded rod 909 counterclockwise. The threaded rod 909 drives the longitudinal pressure plate 910 away from the horizontal plate 10. After the insert rod 911 disengages from the insertion hole 11, push the two pull handles in a direction closer to each other. The pull handles drive the pull plate 906. 906 then drives the positioning rod 904, which moves to one side and compresses the spring 903. After the positioning rod 904 separates from the fixed template 6 or the moving template 5, the fixed template 6 or the moving template 5 is pulled outward to achieve disassembly. During installation, first, the fixed template 6 or the moving template 5 is attached to the fixed mold base plate 1 or the moving mold base plate 3. Then, the two pull plates 906 are pulled in a direction closer together, causing the positioning rod 904 to retract into the receiving hole 902. Then, the two sliders 901 are pushed to move in a direction closer together. Block 901 drives support frame 907, which in turn drives transverse pressure plate 908. When transverse pressure plate 908 is in contact with the side wall of fixed template 6 or moving template 5, the force applied to pull plate 906 stops. Under the push of spring 903, positioning rod 904 resets and inserts into positioning hole 8, achieving transverse positioning of template. Then, pull rod 122 is pulled to one side and turntable 912 is rotated clockwise. Turntable 912 drives threaded rod 909, which in turn drives longitudinal pressure plate 910 to move downward. When insertion rod 911... When the plate is about to contact the horizontal plate 10, rotate the longitudinal pressure plate 910 so that the two bottom insert rods 911 are aligned with the insertion holes 11. Then, restrict the longitudinal pressure plate 910 from rotating and continue to rotate the threaded rod 909. When the threaded rod 909 drives the longitudinal pressure plate 910 to fit against the horizontal plate 10 and the insert rods 911 are inserted into the insertion holes 11, the rotation can be stopped. Then, release the pull rod 122, and the spring 124 will cause the insert plate 123 to reset and insert between the adjacent rectangular plates 913, thus achieving the positioning of the turntable 912 and completing the installation of the template.

[0045] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
