[0025] 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.

[0026] Combined with Figure 1-Figure 5 In this embodiment, an extrusion device for injection molding material includes: a support groove 1, the support groove 1 is in a "U" shape, a telescopic rod 11 is fixedly installed inside the top of the support groove 1, and two lifting grooves 12 are fixedly installed on both sides of the inside of the support groove 1.

[0027] A lifting block 13 is movably connected inside the lifting groove 12, and the lifting block 13 is in the shape of an I-shaped Chinese character.

[0028] Specifically, the injection molding material is heated by heating the inner liner 31, and the lifting block 13 moves up and down inside the lifting slot 12, thereby driving the storage tank 3 to adjust its height, and the telescopic rod 11 is extended and retracted, so that the cover plate 22 moves downward and is engaged and fixed with the two clamping plates 32 on both sides of the top of the storage tank 3.

[0029] A support rod 2 is fixedly installed in the middle of the bottom of the telescopic rod 11, a rotating shaft 21 is fixedly installed on the top of the side of the support rod 2, a cover plate 22 is movably connected to the middle outer side of the rotating shaft 21, and the cover plate 22 is annular in shape. Eight connecting rods 23 are fixedly installed around the middle of the side of the support rod 2, a scraper 24 is fixedly installed on one side of the connecting rod 23, and the scraper 24 is in an "L" shape. A auger 25 is fixedly installed on the bottom of the outer side of the connecting rod 23.

[0030] Specifically, the support rod 2 is driven to rotate by the rotation of the rotating shaft 21. Since the cover plate 22 is movably connected to the middle interior of the rotating shaft 21, when the rotating shaft 21 drives the connecting rod 23 to rotate, the cover plate 22 will not rotate with the rotating shaft 21 because of the interlocking fixation with the two clamping plates 32 on both sides of the top of the storage tank 3. The support rod 2 is driven to rotate by the rotating shaft 21, thereby driving the eight connecting rods 23 on the middle and outer sides of the support rod 2 to rotate, so that the four scrapers 24 connected to one side of the connecting rod 23 are in contact with the inside of the heating liner 31 and rotate, thereby avoiding the problem of injection molding material being adsorbed on the inside of the heating liner 31 and causing inconvenience in cleaning. At the same time, when the scraper 24 and the connecting rod 23 rotate, the injection molding material inside the heating liner 31 will be stirred, so that the injection molding material is heated evenly, avoiding the problem of solidification of the injection molding material, and improving the practicability of the injection molding material extrusion device.

[0031] A connection block 33 is fixedly mounted on one side of the lifting block 13 , and a storage tank 3 is fixedly mounted on one side of the connection block 33 .

[0032] A heating liner 31 is fixedly installed inside the storage tank 3 , and two clamping plates 32 are fixedly installed on both sides of the top of the storage tank 3 .

[0033] A temperature detector 34 is fixedly mounted on one side of the storage tank 3 .

[0034] Specifically, the injection molding material is added into the storage tank 3 , and the injection molding material is heated by the heating liner 31 . The temperature of the injection molding material in the heating liner 31 can be detected in real time by the temperature detector 34 .

[0035] A discharge pipe 4 is fixedly installed at the inner bottom of the heating inner container 31 , and an extrusion port 41 is fixedly installed at the bottom of the discharge pipe 4 .

[0036] The extrusion port 41 is in a funnel shape, and a temperature detector 42 is fixedly mounted on one side of the extrusion port 41 .

[0037] Specifically, the discharge pipe 4 is a structure for discharging materials, and the injection molding material is extruded through the extrusion port 41. The temperature of the material extruded from the extrusion port 41 can be detected in real time by the temperature detector 42, so that the injection molding material extruded from the extrusion port 41 can be adjusted by controlling the heating temperature of the heating liner 31, thereby improving the convenience of the extrusion device of the injection molding material.

[0038] Working principle: First, the injection molding material is added into the storage tank 3, and the injection molding material is heated by the heating liner 31. The lifting block 13 moves up and down in the lifting slot 12, thereby driving the storage tank 3 to adjust its height. The telescopic rod 11 is extended and retracted, so that the cover plate 22 moves downward and is engaged and fixed with the two clamping plates 32 on both sides of the top of the storage tank 3. The support rod 2 is driven to rotate by the rotation of the shaft 21. Since the cover plate 22 is movably connected to the middle of the shaft 21, when the shaft 21 drives the connecting rod 23 to rotate, the cover plate 22 will be moved. The two clamping plates 32 on both sides of the top of the storage tank 3 are engaged and fixed and do not rotate with the rotating shaft 21. The rotating shaft 21 drives the support rod 2 to rotate, thereby driving the eight connecting rods 23 on the middle and outer sides of the support rod 2 to rotate, so that the four scrapers 24 connected to one side of the connecting rod 23 are close to the inside of the heating liner 31 and rotate, thereby avoiding the problem that the injection molding material is adsorbed on the inside of the heating liner 31 and is inconvenient to clean. At the same time, when the scraper 24 and the connecting rod 23 rotate, the injection molding material inside the heating liner 31 is stirred, so that the injection molding material is heated evenly, avoiding The problem of solidification of the injection molding material is solved, and the practicability of the extrusion device of the injection molding material is improved. After the injection molding material is melted, it enters the bottom of the heating inner tank 31, and the rotation of the connecting rod 23 drives the auger 25 to rotate inside the discharge pipe 4, so that the melted material is transported downward by the operation of the auger 25, so that the material is extruded out of the extrusion port 41 through the discharge pipe 4, which improves the practicability of the extrusion device of the injection molding material. The temperature detector 34 can detect the real-time temperature of the injection molding material inside the heating inner tank 31, and the temperature detector 42 can detect the temperature of the extruder. The material extruded from the port 41 is subjected to real-time temperature detection, thereby adjusting the injection molding material extruded from the extrusion port 41 by controlling the heating temperature of the heating liner 31, thereby improving the convenience of the extrusion device for the injection molding material, and avoiding the problem of inconvenience for injection molding caused by too low or too high material temperature during extrusion. By contracting the telescopic rod 11 at the top of the support groove 1, the connecting rod 23, the cover plate 22 and the auger 25 can be driven to move upward, thereby separating from the storage tank 3, so as to facilitate the cleaning of the inside of the extrusion device for the injection molding material, thereby improving the convenience of the extrusion device for the injection molding material.
