Description

Technical Field

[0001] The utility model relates to the field of vertical injection molding machines, and specifically to a forced quantitative feeding device for a vertical injection molding machine. Background Technique

[0002] A vertical injection molding machine is a mechanical device used for injection molding. Its main feature is that the opening and closing direction of the mold is vertical. A vertical injection molding machine can facilitate the loading and unloading and adjustment of the mold more conveniently because the up and down movement of the mold makes it easier for operators to perform these operations.

[0003] When a vertical injection molding machine feeds materials, it uses the method of screw feeding. However, the existing screw feeding has no auxiliary device and completely relies on the self-weight of the materials to fall from a common hopper into the feeding port of the barrel and enter the screw groove for transportation and plasticization. In the case of some special materials, such as soft rubber materials or sheet materials with light self-weight and materials that will stick to each other, it will cause the materials to accumulate at the screw feeding port and unable to enter the screw groove for plasticization, resulting in the failure of the material storage action. Therefore, a forced quantitative feeding device for a vertical injection molding machine is proposed for the above problems. Content of the Utility Model

[0004] In order to make up for the deficiencies of the existing technology, the utility model proposes a forced quantitative feeding device for a vertical injection molding machine.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a forced quantitative feeding device for a vertical injection molding machine, including a hydraulic motor, a screw, and a barrel.

A small electric motor is fixedly connected to the hole opened on the side of the hopper. An electric motor shield is fixedly arranged outside the small electric motor. A speed reducer is arranged on the shaft part of the small electric motor. A connecting transmission shaft is fixedly connected to the lower part of the speed reducer. A spiral transmission rod is fixedly arranged at the output end of the connecting transmission shaft. A support plate is fixedly connected to the lower part of the hopper. The end of the support plate is fixedly connected to the side of the vertical injection molding machine;

[0006] Preferably, the motor seat further includes: a flat seat thrust ball bearing and a tapered roller bearing I. The groove on the upper part of the motor seat frame is rotationally connected to the flat seat thrust ball bearing. The groove on the lower part of the motor seat frame is rotationally connected to the tapered roller bearing I;

[0007] Preferably, the speed reducer further includes a support frame and a fastening nut. The lower part of the speed reducer is fixedly connected to one end of the support frame, and the other end of the support frame is fixedly connected to the side frame of the hopper. The fastening nut is threadedly connected to the upper part of the connecting transmission shaft.

[0008] Preferably, the connecting transmission shaft further includes a second tapered roller bearing and a second deep groove ball bearing. The groove in the upper part of the connecting transmission shaft is rotatably connected to the second tapered roller bearing, and the groove in the lower part of the connecting transmission shaft is rotatably connected to the second deep groove ball bearing.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1.

[0012] 2. By adjusting the speed of the small motor through the speed reducer in the present utility model, the speed of the screw transmission rod is realized, so as to cooperate with the processing speed of the materials in the feed barrel.

[0022] The embodiment of this application discloses a forced quantitative feeding device for a vertical injection molding machine, including a hydraulic motor 13, a screw 8, and a barrel 9. The hydraulic motor 13 is fixedly arranged on the upper part of the vertical injection molding machine. The lower part of the hydraulic motor 13 is fixedly provided with the barrel 9. The middle part of the barrel 9 is rotationally connected to the end of the screw 8. A deep groove ball bearing I 14 is arranged at the lower part of the hydraulic motor 13. A motor seat 15 is arranged at the lower part of the deep groove ball bearing I 14. A transmission shaft 16 is rotationally arranged in the middle of the motor seat 15. A hopper seat 17 is arranged at the lower part of the motor seat 15. A hopper 7 is arranged at the side opening of the vertical injection molding machine. A small motor 3 is fixedly connected to the hole opened on the side of the hopper 7. An electric motor housing 2 is fixedly arranged outside the small motor 3. A reducer 4 is arranged on the shaft part of the small motor 3. A connecting transmission shaft 5 is fixedly connected to the lower part of the reducer 4. A screw drive rod 6 is fixedly arranged at the output end of the connecting transmission shaft 5. A support plate 11 is fixedly connected to the lower part of the hopper 7. The end of the support plate 11 is fixedly connected to the side of the vertical injection molding machine.

[0023] The motor seat 15 further includes: a flat seat thrust ball bearing 151 and a tapered roller bearing I 152. The groove at the upper part of the frame of the motor seat 15 is rotationally connected to the flat seat thrust ball bearing 151. The groove at the lower part of the frame of the motor seat 15 is rotationally connected to the tapered roller bearing I 152.

[0024] The speed reducer 4 further includes: a support frame 41 and a fastening nut 42. The lower part of the speed reducer 4 is fixedly connected to one end of the support frame 41, and the other end of the support frame 41 is fixedly connected to the side frame of the hopper 7. The fastening nut 42 is threadedly connected to the upper part of the connecting transmission shaft 5;

[0025] The connecting transmission shaft 5 further includes: a tapered roller bearing II 51 and a deep groove ball bearing II 52. The groove in the upper part of the connecting transmission shaft 5 is rotatably connected to the tapered roller bearing II 51, and the groove in the lower part of the connecting transmission shaft 5 is rotatably connected to the deep groove ball bearing II 52;

[0026] The hopper 7 further includes a barrel inlet 71. The lower part of the hopper 7 is provided with a barrel inlet 71, and the barrel inlet 71 is fixedly connected to the opening on the side of the vertical injection molding machine.

[0027] Working principle: When using a vertical injection molding machine, it is necessary to pour the material from the opening at the upper part of the hopper 7. At this time, a part of the material will enter the barrel 9 through the barrel inlet 71 at the lower part of the hopper 7. However, since the added material is relatively light in weight, the materials adhere to each other, resulting in a slow process for the material to enter the barrel 9 through the barrel inlet 71. At this time, start the small motor 3. The small motor 3 will drive the speed reducer 4 to act, and then the speed reducer 4 drives the connecting transmission shaft 5, so that the connecting transmission shaft 5 drives the screw transmission rod 6 to rotate. And in the rotating state, since the rod body of the screw transmission rod 6 has spiral blades, the blades drive the adhered materials, and the materials will enter the barrel 9 along with the rotating screw transmission rod 6 through the barrel inlet 71, thus realizing auxiliary feeding. The cooperation between the speed reducer 4 and the small motor 3 can make the speed output by the small motor 3 change the speed through the adjustment of the speed reducer 4, so as to achieve the speed reducer 4 controlling the feeding speed. The material entering the barrel 9 will be driven by the screw 8 and extruded. The screw 8 is driven by the hydraulic motor 13 to drive the transmission shaft 16 to rotate, and the material entering the barrel 9 is extruded after being processed.

[0028] By driving the action of the screw transmission rod 6 by the small motor 3, when the materials entering the hopper 7 are adhered and blocked, the rotation of the screw transmission rod 6 will send the blocked materials into the barrel 9 through the barrel inlet 71 for processing, preventing the materials from accumulating in the hopper 7 for a long time and being unable to enter the barrel 9; through the adjustment of the speed of the small motor 3 by the speed reducer 4, the speed of the screw transmission rod 6 is realized, so as to cooperate with the processing speed of the materials in the barrel 9. When the barrel 9 needs to reduce the material entry, adjust the speed reducer 4 to make the screw transmission rod 6 decelerate, thereby delaying the speed of the materials in the hopper 7 entering the barrel 9.

[0029] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
