[0002] A rubber injection molding machine is a piece of equipment for the production of rubber molded products. It is mainly used for the production of rubber molded products, such as electrical insulation parts, shock pads, seals, shoe soles, and industrial and mining rain boots. A rubber injection molding machine generally includes an injection device, a mold opening and closing device, a heating and cooling device, a hydraulic transmission system, and an electrical control system. There are many types of injection machines.

[0003] Rubber injection molding mainly includes: quantitative feeding - melting and plasticizing - pressure injection - filling and cooling - opening the mold to take out the part. After taking out the plastic part, the mold is closed again to carry out the next cycle.

The adjustment of the feeding speed of the existing rubber raw materials is relatively cumbersome, and the existing rubber raw material particles are prone to jamming problems during the adjustment of the feeding speed; when rubber raw material particles with dust on the surface are input into the injection molding machine, the quality of the products manufactured by injection molding will be reduced.

[0012] Furthermore, one end of a rotating rod is rotatably connected to the end of the movable rod, and the other end of the rotating rod is rotatably connected to the vertical column.

[0013] Furthermore, a rubber pad is fixedly arranged on the side wall of the oscillation push rod.

[0014] Furthermore, the raw material processing mechanism includes an elbow pipe fixedly connected to the bottom of the processing shell. One end of the elbow pipe is fixedly provided with an outer cylinder, and an inner cylinder is fixedly sleeved inside the outer cylinder. A plurality of filter holes are annularly and equidistantly formed on the outer wall of the inner cylinder. A rotating shaft is rotatably connected to the central position inside the inner cylinder.

[0016] Furthermore, a corrugated pipe is fixedly connected between the end of the elbow pipe and the outer cylinder, and the corrugated pipe communicates with the interior of the inner cylinder.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. After adding the rubber raw material into the feeding box, the rubber raw material will slide along the baffle plate to the bottom end of the feeding box, and then be transmitted to the processing shell through the concentration part. When the distance between the bottom end of the baffle plate and the inner wall of the feeding box is larger, the falling speed of the rubber raw material is faster; on the contrary, the falling speed is slower. The oscillation adjusting mechanism can continuously generate oscillation on the feeding box. Since the abutting roller slides and abuts on the side wall of the baffle plate, when the baffle plate is continuously pushed by the oscillation push rod, the feeding box will be pushed to move along the socket column, and then it will quickly return to its original position under the extrusion of the return spring. Thus, the feeding box generates left-right reciprocating oscillation. At this time, the baffle plate will rotate relative to the feeding box. The oscillation adjusting mechanism can adjust the reciprocating pushing distance of the oscillation push rod. In this way, when the left-right moving amplitude of the feeding box increases, the vibration amplitude of the baffle plate will increase. Therefore, the feeding speed of the rubber raw material can be increased. On the contrary, when the left-right moving distance of the feeding box decreases, the feeding speed of the rubber raw material will be reduced. Thus, the feeding speed of the injection molding machine can be quickly adjusted as needed, which is convenient for the molding machine to adjust the injection speed. No matter how it is adjusted, the feeding box is always in an oscillating state, and the rotational opening and closing of the baffle plate will not cause problems of blockage and jamming of the rubber raw material. When the raw material falls into the processing shell, the driving motor 1 drives the dialing plate to continuously turn over, which is convenient for feeding the raw material into the raw material processing mechanism for dust cleaning treatment.

[0019] 2. The driving motor two can drive the eccentric disk to rotate, and the round block will slide in the circular groove of the eccentric disk. In this way, one end of the movable rod can be driven by the round block. Since the end of the movable rod is rotatably connected to the rotating rod, one end of the movable rod can be driven to swing reciprocally. A sliding block and a moving seat are arranged in the sliding hole of the movable rod as a fulcrum. In this way, the other end of the movable rod will also swing reciprocally. The sliding seat can be driven to slide reciprocally in the slide rail column through the linkage rod. Thus, the sliding seat drives the oscillating push rod to push the feeding box reciprocally for oscillation, so as to help the rubber raw material to fall. By driving the adjusting screw rod to rotate through the knob, the moving seat can be driven to slide in the vertical column. Thus, the moving seat can drive the sliding block to slide in the sliding hole. When the sliding block gradually approaches the round block, the swinging range of the end of the movable rod away from the round block will increase. Thus, the reciprocating sliding distance of the driven sliding seat increases. Therefore, the oscillating effect generated by the oscillating push rod will be improved, so as to facilitate the adjustment of the falling speed of the rubber raw material. When the sliding block moves away from the round block, the swinging degree of the end of the movable rod decreases, and correspondingly, the pushing amplitude of the oscillating push rod will be reduced. Therefore, through the oscillating adjustment mechanism, the user can easily adjust the feeding speed of the raw material, and the adjustment method is simple and convenient to use.

[0020] 3. After the rubber particles enter the inner cylinder through the elbow pipe and the corrugated pipe, the driving motor three will drive the rotating shaft and the multiple turning plates on the outer wall to rotate continuously. The turning plates drive the rubber particles to tumble rapidly in the inner cylinder, and the particles collide with each other continuously. In this way, the dust on the surface of the rubber particles can be quickly shaken off. The dust will enter the dust extraction shell through the filter holes on the inner cylinder. At the same time, the dust in the dust extraction shell can be extracted by the suction pump and discharged into the collection box. Therefore, the dust in the dust extraction shell and the outer cylinder can be quickly cleaned, so as to improve the dust cleaning effect on the surface of the rubber particle raw material. Then, the rubber raw material after dust cleaning will enter the extrusion cylinder through the discharge pipe. By driving the extrusion screw to rotate to pressurize the raw material, and at the same time, the heating mechanism can melt the raw material to make the rubber be continuously extruded and injected. The finished product quality of the product injection molded from the rubber raw material after cleaning can be improved, and the molding integrity of the product is improved.

Detailed implementation manners

[0030] 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 making creative efforts belong to the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 8 , in the embodiment of the present invention, a rubber injection molding machine includes a feeding mechanism 100. An oscillation adjusting mechanism 200 is fixedly arranged on one side of the feeding mechanism 100, and a raw material processing mechanism 300 is fixedly arranged at the bottom of the feeding mechanism 100;

[0033] The feeding mechanism 100 includes a feeding box 101. Two limiting columns 103 are symmetrically and fixedly connected to the feeding box 101. The outer parts of the two limiting columns 103 are both slidably sleeved with socket columns 104. A support frame 105 is fixedly connected between the ends of the two socket columns 104. A baffle plate 108 is rotatably connected in the feeding box 101. A torsion spring 109 is fixedly connected to the connection between the baffle plate 108 and the feeding box 101. An abutting roller 107 is slidably abutted against the outer wall of the baffle plate 108. The abutting roller 107 is fixedly connected to the support frame 105. Two reset springs 106 that are fixedly connected to the support frame 105 are symmetrically and fixedly connected to the side wall of the feeding box 101. The opening area at the top of the feeding box 101 is eight times that of the opening area at the bottom. A concentrating part 102 is fixedly arranged at the bottom end of the feeding box 101. A processing shell 110 that is communicated with the inside of the feeding box 101 is fixedly connected to the bottom of the feeding box 101. A material distributing plate 111 is rotatably connected in the processing shell 110. The output end of a driving motor 112 is fixedly connected to the center position at the bottom of the material distributing plate 111.

[0034] Specifically, after adding rubber raw materials into the feeding box 101, the rubber raw materials will slide along the baffle plate 108 to the bottom end of the feeding box 101, and then will be transmitted to the processing shell 110 through the concentrating part 102. When the distance between the bottom end of the baffle plate 108 and the inner wall of the feeding box 101 is larger, the falling speed of the rubber raw materials is faster; on the contrary, the falling speed is slower. The oscillation adjusting mechanism 200 can continuously generate oscillations on the feeding box 101. Since the abutting roller 107 is slidably abutted against the side wall of the baffle plate 108, when the baffle plate 108 is continuously abutted by the oscillation push rod 217, the feeding box 101 will be pushed to move along the socket column 104, and then it will quickly return to its original position under the extrusion of the reset spring 106. Thus, the feeding box 101 generates left - right reciprocating oscillations. At this time, the baffle plate 108 will rotate relative to the feeding box 101. The oscillation adjusting mechanism 200 can adjust the reciprocating pushing distance of the oscillation push rod 217. In this way, when the left - right moving amplitude of the feeding box 101 increases, the vibration amplitude of the baffle plate 108 will increase. Therefore, the feeding speed of the rubber raw materials can be increased. On the contrary, when the left - right moving distance of the feeding box 101 decreases, the feeding speed of the rubber raw materials will be reduced. Thus, the feeding speed of the injection molding machine can be quickly adjusted as needed, which is convenient for the molding machine to adjust the injection speed. No matter how it is adjusted, the feeding box 101 is always in an oscillating state, and the rotational opening and closing of the baffle plate 108 will not cause problems of material blockage and jamming to the rubber raw materials. When the raw materials fall into the processing shell 110, the driving motor 112 drives the material distributing plate 111 to continuously flip, which is convenient for sending the raw materials into the raw material processing mechanism 300 for dust cleaning treatment.

[0035] Such as Figures 5 - 6As shown, in this embodiment, the oscillation adjustment mechanism 200 includes a top support plate 201. A vertical column 202 is fixedly connected to the top of the top support plate 201. The top end of the vertical column 202 is fixedly connected to a slide rail column 203. A second drive motor 204 is fixedly connected to the top of the top support plate 201. An eccentric disk 205 is fixedly connected to the output end of the second drive motor 204. A circular groove 206 is formed in the eccentric disk 205. A circular block 207 is slidably and embeddedly connected in the circular groove 206. One end of the circular block 207 is fixedly connected to one end of a movable rod 208. A slide hole 209 is formed in the movable rod 208. A sliding block 210 is slidably and embeddedly connected in the slide hole 209. One side of the sliding block 210 is rotatably connected to a moving seat 211 that is slidably connected to the vertical column 202. The other end of the movable rod 208 is rotatably connected to one end of a linkage rod 215. The other end of the linkage rod 215 is rotatably connected to a sliding seat 216. The sliding seat 216 is slidably connected to the slide rail column 203. An oscillation push rod 217 is fixedly connected to the side wall of the sliding seat 216. The oscillation push rod 217 abuts against the outer wall of the feed box 101; an adjustment screw rod 212 is rotatably sleeved in the moving seat 211. The adjustment screw rod 212 is rotatably connected to the vertical column 202. A knob 213 is fixedly connected to the top end of the adjustment screw rod 212; one end of a rotating rod 214 is rotatably connected to the end of the movable rod 208. The other end of the rotating rod 214 is rotatably connected to the vertical column 202; a rubber pad is fixedly arranged on the side wall of the oscillation push rod 217.

[0036] During specific implementation, the drive motor two 204 can drive the eccentric disc 205 to rotate, and the round block 207 will slide in the circular groove 206 of the eccentric disc 205. In this way, the round block 207 can drive one end of the movable rod 208. Since the end of the movable rod 208 is rotatably connected to the rotating rod 214, one end of the movable rod 208 can be driven to swing reciprocally. A sliding block 210 and a moving seat 211 are arranged in the sliding hole 209 of the movable rod 208 as fulcrums. In this way, the other end of the movable rod 208 will also swing reciprocally. Through the linkage rod 215, the sliding seat 216 can be driven to slide reciprocally in the slide rail column 203. Thus, the sliding seat 216 drives the oscillating push rod 217 to push the feeding box 101 reciprocally for oscillation, so as to help the rubber raw material to fall. By driving the adjusting screw rod 212 to rotate through the knob 213, the moving seat 211 can be driven to slide in the vertical column 202. Thus, the moving seat 211 can drive the sliding block 210 to slide in the sliding hole 209. When the sliding block 210 gradually approaches the round block 207, the swinging range of the end of the movable rod 208 different from the round block 207 will increase, so that the reciprocating sliding distance of the sliding seat 216 is increased. Therefore, the oscillating effect generated by the oscillating push rod 217 will be improved, so as to facilitate the adjustment of the falling speed of the rubber raw material. When the sliding block 210 is far away from the round block 207, the swinging degree of the end of the movable rod 208 is reduced, and correspondingly, the pushing amplitude of the oscillating push rod 217 is reduced. Therefore, through the oscillation adjusting mechanism 200, the user can easily and quickly adjust the feeding speed of the raw material, and the adjustment method is simple and convenient to use.

[0038] As Figures 7 - 8As shown in the figure, in this embodiment, the raw material processing mechanism 300 includes an elbow pipe 301 fixedly connected to the bottom of the processing shell 110. One end of the elbow pipe 301 is fixedly provided with an outer cylinder 303. An inner cylinder 304 is fixedly sleeved inside the outer cylinder 303. A plurality of filter holes 305 are annularly and equidistantly formed on the outer wall of the inner cylinder 304. A rotating shaft 306 is rotatably connected to the central position inside the inner cylinder 304. A plurality of turning plates 307 are annularly and equidistantly fixedly connected to the outer wall of the rotating shaft 306. The end of the rotating shaft 306 is fixedly connected to the output end of a third driving motor 308. The end of the inner cylinder 304 is fixedly connected to a discharge pipe 313 communicating with its interior. The bottom end of the discharge pipe 313 is fixedly connected to an extrusion cylinder 314. An extrusion screw 316 is rotatably sleeved inside the extrusion cylinder 314. The end of the extrusion screw 316 is fixedly connected to the output end of a servo motor 317. A positioning seat 315 is fixedly sleeved outside the extrusion cylinder 314. A dust extraction shell 309 communicating with its interior is fixedly connected to the outer wall of the outer cylinder 303. The input end of a dust extraction air pump 310 is fixedly connected to the bottom end of the dust extraction shell 309. The output end of the dust extraction air pump 310 is fixedly connected to a collection box 311. A dust filter plate 312 is slidably clamped inside the collection box 311. A bellows 302 is fixedly connected between the end of the elbow pipe 301 and the outer cylinder 303. The bellows 302 communicates with the interior of the inner cylinder 304.

[0039] During specific implementation, when the rubber particles enter the inner cylinder 304 through the elbow pipe 301 and the bellows 302, the third driving motor 308 drives the rotating shaft 306 and the plurality of turning plates 307 on the outer wall to rotate continuously. The turning plates 307 drive the rubber particles to rapidly tumble in the inner cylinder 304, and the particles continuously collide with each other, so that the dust on the surface of the rubber particles can be quickly shaken off. The dust will enter the dust extraction shell 309 through the filter holes 305 on the inner cylinder 304. At the same time, the dust extraction air pump 310 can extract the dust in the dust extraction shell 309 and discharge it into the collection box 311. Therefore, the dust in the dust extraction shell 309 and the interior of the outer cylinder 303 can be quickly cleaned, thereby improving the dust cleaning effect on the surface of the rubber particle raw materials. Then, the rubber raw materials after dust cleaning enter the extrusion cylinder 314 through the discharge pipe 313. By driving the extrusion screw 316 to rotate to pressurize the raw materials, and at the same time, the heating mechanism melts the raw materials, the rubber can be continuously extruded and injected. The finished product quality of the product injection-molded from the rubber raw materials after cleaning can be improved, and the molding integrity of the product is improved.
