There are roughly more than 200 classifications of plastic particles, and the subdivision can reach thousands. Common plastic particles include general plastics, engineering plastics, and special plastics. When processing plastic particles, it is necessary to stir the ingredients to make them fully mixed.

[0003] A plastic particle mixing device for injection molds is disclosed in the prior art. In this device, a motor drives a threaded rod to rotate, and the threaded rod drives a threaded sleeve to slide on the inner wall of a slide rail. At the same time, pulling the threaded sleeve causes the angle of a connecting rod to change at the bottom of a connecting block, and makes the main body of the device tilt at the top of a support rod, and the manufactured plastic particles are discharged, facilitating quick feeding.

[0004] However, this device still has some defects. In actual use, manual feeding is adopted in this device, and manual feeding cannot accurately control the amount of each feeding. Due to the inability to accurately control the feeding amount, it may lead to overfeeding or underfeeding of raw materials, resulting in waste of raw materials.

[0005] Therefore, it is necessary to provide a plastic particle mixing device for injection molds to solve the above technical problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described below in conjunction with the drawings and embodiments. The embodiments of the present utility model include but are not limited to the following embodiments.

[0026] First Embodiment:

[0027] As Figure 1-6As shown in the figure, the plastic particle mixing equipment of the injection mold provided by the present utility model includes: a mixing table 100, the mixing table 100 includes a base 101 and a support frame 102. A stirring assembly 400 is arranged on the base 101. The stirring assembly 400 includes a mixing barrel 401. A collection box 500 is arranged at the discharge port of the mixing barrel 401. A turntable 402 is also arranged in the mixing barrel 401. A rotating arm 403 is sleeved at the center of the turntable 402. A stirring rod 405 is sleeved on the rotating arm 403. A metering assembly 300 and a feeding barrel 200 are also arranged on the mixing barrel 401. The feeding barrel 200 includes a discharge cavity opening 201. The discharge cavity opening 201 is engaged with a locking ring 302 provided by the metering assembly 300. The locking ring 302 is arranged at the upper end of a metering box 301. A fixing frame 303 is also arranged in the metering box 301. The fixing frame 303 is fixed in the metering box 301 through a positioning member 309. A moving plate 305 is also arranged in the fixing frame 303. A metering barrel 306 is communicated with the end side of the moving plate 305. A baffle 308 is arranged below the metering barrel 306. The lower part of the metering box 301 is communicated with the mixing barrel 401. A hydraulic cylinder 304 is also connected to the end side of the moving plate 305. The staff pours the plastic particle raw materials into the feeding barrel 200. Since the discharge cavity opening 201 is fixedly engaged with the locking ring 302, the metering barrel 306 provided by the moving plate 305 is communicated with the locking ring 302. At this time, by starting the metering assembly 300, during actual use, by controlling the telescopic movement of the hydraulic cylinder 304, the left and right movement of the moving plate 305 is realized. Through the left and right movement of the moving plate 305, the left and right movement of the metering barrel 306 is driven. When the metering barrel 306 is filled with raw materials, the hydraulic cylinder 304 drives the metering barrel 306 to move to one end. When the lower part of the metering barrel 306 breaks away from the resistance of the baffle 308, at this time, the movable cover 307 opens, and the raw materials are poured into the mixing barrel 401 through the through hole provided by the metering box 301. Through the reciprocating movement of the hydraulic cylinder 304, quantitative feeding is realized. At this time, the raw materials poured in are stirred and mixed by the stirring rod 405 arranged in the mixing barrel 401. Finally, the mixed raw materials are collected into the collection box 500 through a control valve.

[0028] Through the coordinated use of multiple parts in the set metering assembly 300, quantitative feeding can be realized. By quantitative feeding, overfeeding of raw materials can be prevented. During actual use, by quantitatively pouring plastic particles, it can be ensured that the proportion of raw materials for each mixing is consistent. At the same time, due to the consistent proportion of raw materials, the stirring process helps to distribute additives more evenly and quickly, thereby improving the mixing efficiency.

[0029] Second Embodiment:

[0030] As Figure 4As shown, a movable cover 307 is also hingedly provided below the metering bucket 306. The caliber size of the movable cover 307 is the same as that of the metering bucket 306. In actual use, through the combined use of the provided movable cover 307 and the metering bucket 306, the metering and feeding of raw materials can be achieved through the metering bucket 306. At the same time, through the combined use of the movable cover 307, plastic particles can be prevented from falling onto the baffle 308, thereby ensuring a clean environment inside the metering box 301.

[0031] Third Embodiment:

[0032] As Figure 4-5 shown, a chute is also provided inside the fixed frame 303. The moving plate 305 moves left and right in the chutes provided on both sides inside the fixed frame 303. In actual use, when the hydraulic cylinder 304 is driven, the hydraulic cylinder 304 drives the moving plate 305 to move left and right in the chute provided in the fixed frame 303.

[0033] Through the provided fixed frame 303 and the chute, in actual use, the moving plate 305 moves left and right in the chute provided in the fixed frame 303, thereby reducing the friction during the movement of the moving plate 305. In actual use, the moving plate 305 moves more smoothly, avoiding jamming. At the same time, through the reduction of friction, the energy required for the hydraulic pump to provide oil pressure can be reduced, thereby saving energy consumption.

[0034] Fourth Embodiment:

[0035] As Figure 6 shown, a connecting shaft 404 is also sleeved on the rotating arm 403. Stirring rods 405 are symmetrically installed at both ends of the connecting shaft 404. Through holes are arrayed on the stirring rods 405. In actual use, when plastic particles are quantitatively poured into the mixing bucket 401, the turntable 402 is driven to rotate by controlling the power supply. Through the rotation of the turntable 402, the stirring of raw materials by the stirring rods 405 is realized.

[0036] Through the combined use of the provided connecting shaft 404 and the stirring rods 405, in actual use, through the through holes arrayed on the stirring rods 405, the through holes allow raw materials to flow and exchange positions more easily during the stirring process. This can accelerate the uniform mixing between different components. At the same time, since the through holes provide more flow channels, the time required for plastic particles to reach sufficient mixing can be reduced, thereby improving production efficiency.

[0037] Fifth Embodiment:

[0038] As Figure 6As shown, a connection frame 406 is further provided on the connection shaft 404. The caliber of the connection frame 406 is the same as that of the stirring rod 405, and the two are detachably and fixedly installed through the provided pre-tightening bolts. Through the connection frame 406 provided on the end side of the connection shaft 404, during actual installation, only the end of the stirring rod 405 needs to be inserted into the connection frame 406. At this time, the positioning holes provided on the stirring rod 405 are aligned with the pre-tightening bolts provided on the connection frame 406, and finally, the fixed installation can be completed by screwing the pre-tightening bolts.

[0039] Through the combined use of the provided connection frame 406 and the pre-tightening bolts, the rapid installation and disassembly of the stirring rod 405 can be realized. At the same time, through the fitting of the connection frame 406 and the stirring rod 405, and through their fitting connection, the occurrence of gaps during their connection is prevented, thereby ensuring the stability of their connection.

[0040] Sixth Embodiment:

[0041] As Figure 2-3 shown, a door body is provided on the end side of the metering box 301, and the door body can be opened by 90°. During actual use, due to the door body provided on the end side of the metering box 301 being an openable structure, when the device is used for a long time, through the openable door body setting, it is convenient for subsequent staff to maintain the parts in the metering box 301.

[0042] Working raw materials: The staff pour the plastic particle raw materials into the feeding bucket 200. Since the discharge cavity opening 201 is fixedly clamped with the lock ring 302, the metering bucket 306 provided on the moving plate 305 is communicated with the lock ring 302. At this time, by starting the metering component 300, during actual use, by controlling the telescopic movement of the hydraulic cylinder 304, the left and right movement of the moving plate 305 is realized. Through the left and right movement of the moving plate 305, the left and right movement of the metering bucket 306 is driven. When the metering bucket 306 is filled with raw materials, the hydraulic cylinder 304 drives the metering bucket 306 to move to one end. When the lower part of the metering bucket 306 is separated from the resistance of the baffle 308, the movable cover 307 opens at this time, and the raw materials are poured into the mixing bucket 401 through the through hole provided in the metering box 301. Through the reciprocating movement of the hydraulic cylinder 304, quantitative feeding is realized. At this time, the raw materials poured in are stirred and mixed by the stirring rod 405 provided in the mixing bucket 401, and finally the mixed raw materials are collected into the collection box 500 through the control valve.

[0043] The above embodiments are only one of the preferred embodiments of the present invention and should not be used to limit the protection scope of the present invention. Any meaningless changes or touch-ups made on the main design concept and spirit of the present invention, as long as the technical problems solved are still the same as those of the present invention, should be included in the protection scope of the present invention.
