[0002] Injection molds are tools used for injection molding, usually composed of lower mold base, mold core, template, cooling system and other components. During the installation of injection molds, it is necessary to consider aspects such as mold positioning, fixation, and debugging to ensure that the mold can work accurately and stably.

[0003] At present, the injection mold closes the upper and lower parts together to form a closed cavity, namely the mold cavity, and then heats and melts the plastic particles into the mold cavity through the nozzle, maintaining a certain pressure to ensure that the plastic flows fully and fills the details in the mold. The fixed plastic is then removed after cooling by the cooling system. However, the mold body is mostly fixed to the lower mold base with screws and nuts, and replacement and installation require additional tools, which is troublesome. Secondly, demolding of some injection molds is troublesome. Therefore, an injection mold that is convenient for mold installation is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3The utility model provides an embodiment: an injection mold for convenient mold installation, comprising a lower mold base 1, the top of the lower mold base 1 contacts the upper mold base 2, four groups of plug blocks 4 are fixedly connected to the top of the lower mold base 1, four groups of slots 5 are provided at the bottom of the upper mold base 2, the outer walls of the plug blocks 4 are plugged into the inner walls of the slots 5, and the plug blocks 4 are aligned with the slots 5 and inserted, so that the lower mold base 1 and the upper mold base 2 can be connected together to form a closed cavity with the central mold, and an injection port 3 is provided at the top of the upper mold base 2, and the heated and melted plastic particles are injected into the cavity through the injection port 3, and the inner walls of the upper mold base 2 and the lower mold base 1 can be detachably connected with a mold body 6, and the inner wall of the mold body 6 is provided with four groups of circular grooves 17, and the inner walls of the upper mold base 2 and the lower mold base 1 are fixedly connected with a columnar block 7, and the outer wall of the columnar block 7 is plugged into the inner wall of the circular groove 17, and the mold body 6 can be installed on the mold base by aligning the circular groove 17 with the columnar block 7 and putting it on, and the inner wall of the columnar block 7 is slidably connected with a pull rod 8, and the inner wall of the pull rod 8 slides The movable connection is provided with a snap assembly, which includes two groups of card blocks 9. The outer walls of the two groups of card blocks 9 are slidably connected to the inner wall of the pull rod 8. The interval between the two groups of card blocks 9 is elastically connected by a reset spring 10. The two ends of the reset spring 10 are respectively fixedly connected to the inner end of the two groups of card blocks 9. The outer walls of the two groups of card blocks 9 are set as inclined surfaces. In the process of putting the circular groove 17 on the cylindrical block 7, the inner wall of the circular groove 17 squeezes the inclined surface of the card block 9 to squeeze the reset spring 10 to retract. At the same time, the elastic force generated by the deformation of the reset spring 10 is given The two groups of blocks 9 push outward to reset themselves. When the circular groove 17 slides to the bottom of the columnar block 7, the block 9 pops out and clamps the outer wall of the mold body 6 to fix it on the mold seat. The bottom end of the block 9 is clamped with the outer wall of the mold body 6. When the mold body 6 needs to be removed, the two groups of blocks 9 are pressed inward and the pull rod 8 is pulled upward to make the block 9 completely retracted while pressing against the inner wall of the columnar block 7 to prevent it from popping out. The outer wall of the block 9 is in contact with the inner wall of the columnar block 7. At this time, the mold body 6 can be removed and replaced.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The inner wall of the lower mold base 1 is rotatably connected with a threaded rod 11, and the end of the threaded rod 11 is fixedly connected with a knob 12. Turning the knob 12 can drive the threaded rod 11 to rotate. The outer wall of the threaded rod 11 is threadedly connected with two groups of threaded sleeves 13. The inner walls of the two groups of threaded sleeves 13 are set as reverse threads. The threaded rod 11 rotates to move closer to or separate from each other. The top of the threaded sleeve 13 is hinged with a bracket 14, and the top of the bracket 14 is hinged with a lifting plate 15. The position change of the two groups of threaded sleeves 13 will drive the angle of the bracket 14 to deviate, thereby controlling the lifting of the lifting plate 15. The side wall of the lifting plate 15 is slidably connected to the inner wall of the lower mold base 1, and the top of the lifting plate 15 is fixedly connected with an ejector pin 16. The outer wall of the ejector pin 16 is slidably connected to the inner wall of the mold body 6. The lifting of the lifting plate 15 can drive the ejector pin 16 to eject the cooled plastic for quick demoulding.

[0032] Working principle: close the upper and lower sets of mold bases and cooperate with the two sets of mold bodies 6 to form a mold cavity in the center, and then inject the heated plastic particles into the mold cavity through the injection port 3. After that, the plastic particles fill the mold cavity under the action of pressure and are shaped. When the shaped plastic needs to be taken out after cooling, turn the knob 12 to rotate the threaded rod 11, so that the position of the two sets of threaded sleeves 13 changes, driving the angle of the bracket 14 to move the lifting plate 15 upward, and control the ejector pin 16 to achieve rapid demolding. When the mold body 6 needs to be replaced, press the two sets of card blocks 9 inward, pull the pull rod 8 upward, so that the card blocks 9 are completely retracted and against the inner wall of the columnar block 7. Repeat the above operation for the four sets of buckle components, and the mold body 6 can be removed from the mold base. When installing, align the circular groove 17 with the columnar block 7 and put it on. The installation and disassembly are relatively simple and no additional tools are required.
