Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 7 , the present invention provides a technical solution:

[0027] A wood-plastic new material injection molding device includes an injection molding device 1. A first disassembly and assembly mechanism 2 and a second disassembly and assembly mechanism 3 are arranged inside the injection molding device 1 for quickly replacing the mold. The first disassembly and assembly mechanism 2 includes:

[0028] An installation unit 21 is arranged inside the injection molding device 1 and includes an installation box 211. A limit seat 212 is fixedly installed inside the installation box 211. A clamping block 213 is slidably installed inside the limit seat 212. One end of the clamping block 213 is fixedly installed with a sliding column 214. A swivel ring 215 is rotatably installed inside the installation box 211. Four inclined grooves 216 are opened inside the swivel ring 215. The sliding column 214 is slidably adapted inside the inclined groove 216. A fixed ring 2110 is fixedly installed inside the installation box 211. The end of the clamping block 213 away from the sliding column 214 penetrates inside the fixed ring 2110. A limit driving component 4 is arranged on the top of the installation box 211;

[0029] An insertion unit 22 is arranged on one side of the injection molding device 1 and is used for installing the template.

[0030] In this embodiment, a linkage rod 217 is fixedly installed above the swivel ring 215, and a sliding groove 218 is formed inside the linkage rod 217. A rectangular groove 219 is formed at the top of the mounting box 211, and the linkage rod 217 slides inside the rectangular groove 219.

[0031] When the swivel ring 215 rotates counterclockwise, the swivel ring 215 drives the sliding columns 214 to move towards the center through four inclined grooves 216 inside. The four sliding columns 214 drive the clamping blocks 213 to slide towards the center inside the limit seat 212. The inclined surface of the clamping block 213 contacts one side of the chuck 223 close to the insertion unit 22, fixing the chuck 223, thereby realizing the rapid installation of the movable mold 5. The rapid installation of the mold improves production efficiency and reduces production costs.

[0032] In this embodiment, the limit driving assembly 4 includes a mounting frame 41 fixedly installed on the top of the mounting box 211. A lead screw 42 is rotatably installed inside the mounting frame 41. A threaded collar 43 is rotatably installed on the surface of the lead screw 42. Sliding columns 44 are fixedly installed on both sides of the threaded collar 43, and the sliding columns 44 are slidably fitted inside the sliding groove 218. One end of the lead screw 42 penetrates through the mounting frame 41 and is fixedly installed with a handwheel 45.

[0033] When the user rotates the handwheel 45 clockwise, the handwheel 45 drives the threaded collar 43 to move towards the handwheel 45. At the same time, the sliding columns 44 slide inside the sliding groove 218, thereby pulling the linkage rod 217. The linkage rod 217 realizes the rotation of the swivel ring 215. Through the drive of the lead screw 42 and the threaded collar 43, the position of the linkage rod 217 is prevented from changing, thereby improving the stability of the clamping block 213 for clamping the chuck 223.

[0035] In this embodiment, the structures of the first disassembly and assembly mechanism 2 and the second disassembly and assembly mechanism 3 are the same. A fixed mold 6 is fixedly installed on one side of the second disassembly and assembly mechanism 3, and a material injection hole 7 is formed through the center of the second disassembly and assembly mechanism 3, and the material injection hole 7 communicates with the inside of the fixed mold 6.

[0036] In this embodiment, the injection molding device 1 includes a chassis 11. A sliding frame 12 is fixedly installed at the top of the chassis 11. A first hydraulic rod 13 is fixedly installed at the left end of the sliding frame 12. A sliding seat 14 is slidably installed inside the sliding frame 12.

A fixed seat 18 is fixedly installed inside the sliding frame 12. The end of the heating and extrusion tube 17 where the extrusion head 19 is installed penetrates through the inside of the fixed seat 18. The output end of the second hydraulic rod 15 is inserted into the inside of the heating and extrusion tube 17. The second disassembly and assembly mechanism 3 is arranged on one side of the fixed seat 18. The mounting box 211 is fixedly installed on one side of the sliding seat 14.

[0037] When the first hydraulic rod 13 operates to push the sliding seat 14, the first disassembly and assembly mechanism 2 is engaged with the second disassembly and assembly mechanism 3. At this time, the injection raw material enters the inside of the heating and extrusion tube 17 through the feed hopper 16. At the same time, the second hydraulic rod 15 operates, and the push rod at the output end of the second hydraulic rod 15 slides inside the heating tube, and the heated raw material is injected into the inside of the injection hole 7 through the extrusion head 19, and is squeezed into the inside of the movable mold 5 and the fixed mold 6 through the injection hole 7 to complete the injection molding of the product.

[0038] At the same time, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.

At this time, the user rotates the handwheel 45 clockwise. The handwheel 45 drives the threaded collar 43 to move towards the handwheel 45. At the same time, the sliding column 44 slides inside the sliding groove 218, thereby pulling the linkage rod 217. The linkage rod 217 drives the rotating ring 215 to rotate counterclockwise. The rotating ring 215 rotates counterclockwise. The rotating ring 215 drives the four sliding columns 214 to move towards the center through the four inclined grooves 216 inside. The four sliding columns 214 drive the clamping blocks 213 to slide towards the center inside the limit seat 212. The inclined surface of the clamping block 213 contacts the side of the chuck 223 close to the insertion unit 22 to fix the chuck 223, and the fixed mold 6 is quickly connected to the fixed seat 18 through the second disassembly and assembly mechanism 3;

[0040] Then, the first hydraulic rod 13 operates to push the sliding seat 14, so that the first disassembly and assembly mechanism 2 is combined with the second disassembly and assembly mechanism 3. At this time, the injection raw material enters the inside of the heating and extrusion pipe 17 through the feeding hopper 16. At the same time, the second hydraulic rod 15 operates, and the push rod at the output end of the second hydraulic rod 15 slides inside the heating pipe, and the heated raw material is injected into the injection hole 7 through the material extrusion head 19, and is squeezed into the inside of the movable mold 5 and the fixed mold 6 through the injection hole 7 to complete the injection molding of the product.
