[0004] Although the aforementioned plastic particle heating mold head is efficient, safe, and durable during use, it is inconvenient to quickly disassemble the mold head after use for cleaning and processing. Therefore, it is necessary to design a plastic particle heating mold head. Utility Model Content

[0005] The purpose of this invention is to provide a plastic particle heating die head to solve the problem that existing plastic particle heating dies are inconvenient to quickly disassemble after use for cleaning and processing of the inside of the die head.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plastic particle heating mold head, including a mold head body;

[0007] A discharge hopper is provided at one end of the die head body, and a quick-release structure is provided between the die head body and the discharge hopper;

[0008] The quick-release structure includes a second mounting plate fixed to one end of the mold head body, and the interior of the second mounting plate is evenly provided with slots.

[0009] The second mounting plate is provided with a first mounting plate on the side near the discharge hopper. The first mounting plate has reserved slots evenly opened inside. Each slot has a rotating shaft inside. The outer wall of the rotating shaft inside the slot is evenly fixed with a locking block. The end of the rotating shaft away from the locking block extends through the reserved slot to the outside of the first mounting plate and is fixed with a rotating handle.

[0010] Furthermore, the die head body includes a shell, a side cover plate, an inner cavity, and a feed pipe. The inner cavity is opened inside the shell, and a side cover plate is fixedly connected to one end of the shell. A feed pipe is fixed to one side inside the side cover plate.

[0011] Furthermore, a sealing structure is provided on the side of the outer shell near the side cover plate, and a heating structure is provided inside the inner cavity.

[0012] Furthermore, the sealing structure includes a sealing cavity, a sealing ring, a deformation groove, a positioning rod, and a deformation groove. The sealing cavity is evenly distributed on the side of the side cover plate near the outer shell. A sealing ring is provided inside the sealing cavity, and a deformation groove is provided inside the sealing ring. Positioning grooves are evenly distributed inside the side cover plate on one side of the sealing cavity, and positioning rods are provided inside each positioning groove.

[0013] Furthermore, the sealing ring and the side cover plate are connected by an interference fit through the sealing cavity, and the end of the positioning rod away from the side cover plate is fixedly connected to the outer wall of the outer shell.

[0014] Furthermore, the heating structure includes a heating base, a heating cavity, a heating wire, and a heat-conducting plate. The heating base is fixed to the inner wall of the inner shell of the side cover plate. The heating base has a heating cavity inside, and a heating wire is installed inside the heating cavity. A heat-conducting plate is fixed on the inner wall of the heating base.

[0015] Furthermore, the rotating shafts are evenly distributed inside the second mounting plate, and the locking blocks are engaged with the second mounting plate via locking slots.

[0016] Furthermore, both sides of the card block abut against the inner wall of the second mounting plate, and the card blocks are symmetrically distributed on both sides of the rotating shaft.

[0017] The advantages of the plastic particle heating mold head provided by this utility model are as follows:

[0018] The sealing structure can increase the sealing between the outer shell and the side cover plate; the heating structure can facilitate the heating of plastic particles; and the quick-release structure can be installed quickly. By rotating the locking block, the locking block and the second mounting plate can be connected by the locking slot.

[0019] By incorporating a quick-release structure, the connecting action of the first mounting plate facilitates the insertion of the rotating shaft and the locking block into the slot. The locking action of the locking block and the second mounting plate allows for easy fixation of the locking block and the second mounting plate, thus securing the first and second mounting plates together. The inclusion of multiple sets of locking blocks ensures the stability of the connection between the first and second mounting plates, enabling the device to be easily installed and disassembled, thereby improving the convenience of using the plastic particle heating die head.

[0020] By incorporating a heating structure, the plastic particles can be easily heated and melted under the heating action of the heating wire. The heat conduction effect of the heat conduction plate allows the heat to be more evenly conducted to the interior of the cavity. At the same time, the heat conduction plate can protect the inner wall of the heating seat, preventing the plastic particles from scratching the inner wall of the heating seat. This device achieves the functions of easy heating and heat conduction, improving the working efficiency of the plastic particle heating die head during use.

[0021] By setting a sealing structure, heat loss can be avoided under the sealing effect of the sealing ring, while ensuring the tightness of the connection between the side cover plate and the outer shell, preventing plastic particles from falling into the gap between the outer shell and the side cover plate. This enables the device to have the function of easily sealing the connection between the outer shell and the side cover plate, improving the convenience of using the plastic particle heating die head.

[0022] The sealing ring is circular and can completely seal the gap between the outer shell and the side cover plate, preventing heat from escaping through the gap. The heating wire is spirally distributed inside the heating chamber, ensuring uniform heat distribution during heating. The two sides of the locking block and the inner wall of the second mounting plate abut against each other, thus fixing the locking block and the second mounting plate together. When disassembly is required, simply rotate the locking block again so that it can be removed outward through the reserved slot. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 The present invention provides a plastic particle heating mold head, including a mold head body 1.

[0032] Reference Figure 1 , Figure 2 and Figures 4-6 The die head body 1 includes a shell 11, a side cover plate 12, an inner cavity 13, and a feed pipe 14. The inner cavity 13 is formed inside the shell 11. One end of the shell 11 is fixedly connected to the side cover plate 12. The feed pipe 14 is fixed to one side inside the side cover plate 12. A discharge hopper 4 is provided at one end of the die head body 1. A quick-release structure 5 is provided between the die head body 1 and the discharge hopper 4. The quick-release structure 5 includes a second mounting plate 54 fixed to one end of the die head body 1. The interior of the second mounting plate 54 is evenly provided with slots 55. A first mounting plate 5 is provided on the side of the second mounting plate 54 near the discharge hopper 4. 3. The first mounting plate 53 has evenly spaced reserved slots 52 inside. Each slot 55 has a rotating shaft 56 inside. Each rotating shaft 56 inside the slot 55 has a locking block 57 evenly fixed on the outer wall of the rotating shaft 56 inside the slot 55. The end of the rotating shaft 56 away from the locking block 57 extends through the reserved slot 52 to the outside of the first mounting plate 53 and is fixed with a rotating handle 51. The rotating shaft 56 is evenly distributed inside the second mounting plate 54. The locking block 57 is engaged and connected to the second mounting plate 54 through the slot 55. Both sides of the locking block 57 abut against the inner wall of the second mounting plate 54. The locking blocks 57 are symmetrically distributed on both sides of the rotating shaft 56.

[0033] During installation, the rotating shaft 56 and the locking block 57 are inserted into the slot 55 through the reserved slot 52. Then, the rotating handle 51 is rotated, and the rotating handle 51 will drive the locking block 57 to rotate through the rotating shaft 56. When the locking block 57 rotates, its outer side wall will gradually contact the inner side wall of the second mounting plate 54. Rotating the rotating handle 51 ninety degrees will rotate the locking block 57 into the slot 55, so that the locking block 57 and the second mounting plate 54 come into contact with each other. When disassembly is required, the rotating handle 51 is rotated again so that the shapes of the locking block 57 and the reserved slot 52 match each other. The interface removes the locking block 57 through the reserved slot 52, completing the disassembly.

[0034] Reference Figures 2-5 A sealing structure 2 is provided on the side of the outer shell 11 near the side cover plate 12. The sealing structure 2 includes a sealing cavity 21, a sealing ring 22, a deformation groove 23, and a positioning rod 24.

The deformation groove 23 is opened inside the sealing ring 22. The positioning groove 25 is evenly opened inside the side cover plate 12 on one side of the sealing cavity 21. The positioning rod 24 is provided inside the positioning groove 25. The sealing ring 22 and the side cover plate 12 are connected by interference fit through the sealing cavity 21. The end of the positioning rod 24 away from the side cover plate 12 is fixedly connected to the outer wall of the outer shell 11.

[0035] Positioning rod 24 is inserted into positioning groove 25 for positioning. At this time, sealing ring 22 can accurately enter the sealing cavity 21. Then, press side cover plate 12 so that sealing ring 22 can be inserted into sealing cavity 21. Fix the outer shell 11 and side cover plate 12 with bolts. Under the action of compression, sealing ring 22 will deform and fill sealing cavity 21, thereby ensuring the sealing between outer shell 11 and side cover plate 12.

[0036] Reference Figure 2 , Figure 4 and Figure 5 The inner cavity 13 is provided with a heating structure 3, which includes a heating seat 31, a heating cavity 32, a heating wire 33 and a heat-conducting plate 34. The heating seat 31 is fixed to the inner wall of the inner shell 11 of the side cover plate 12. The heating seat 31 has a heating cavity 32 inside, and the heating cavity 32 is provided with a heating wire 33 inside. The heat-conducting plate 34 is fixed on the inner wall of the heating seat 31.

[0037] When the heating wire 33 is activated, it generates heat. After generating heat, the heating wire 33 exchanges heat with the air inside the heating chamber 32. Subsequently, the hot air exchanges heat with the heating base 31. Finally, the heat is introduced into the interior of the side cover plate 12 through the heat conduction plate 34, which facilitates the heating and melting of the plastic particles.
