Description

Technical Field

[0001] This utility model belongs to the field of industrial production equipment technology, specifically relating to a high-efficiency feeding buffer device for an injection molding machine used in the production of automotive parts. Background Technology

[0002] Injection-molded parts are an indispensable part of automobile manufacturing. They are manufactured through injection molding and have advantages such as high precision, fast production efficiency, and low cost.

[0003] The feeding mechanism of an injection molding machine is an important component of the machine. It is responsible for feeding raw materials into the hopper of the injection molding machine, providing sufficient raw materials to ensure the normal operation of the machine.

[0004] Existing feeding mechanisms typically employ a conveyor belt structure, which delivers raw materials into the injection molding machine hopper at a uniform speed. This type of feeding structure cannot quantitatively buffer the raw materials or adjust the feeding speed according to actual production needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the feeding mechanism of the existing injection molding machine cannot adjust the feeding rate.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows: A high-efficiency material feeding and buffering device for an injection molding machine used in automotive parts production is provided, including an injection molding machine inlet, a storage hopper at the top of the inlet, a support arm fixedly connected to the top of the storage hopper, a material distribution mechanism fixedly connected to the bottom of the storage hopper, first support columns fixedly connected to both ends of the support arm, a second support column slidably connected to the bottom of the first support column, a roller movably connected to the bottom of the second support column, and a lifting adjustment mechanism at the top of the second support column, the lifting adjustment mechanism penetrating the side wall of the first support column and rotatably connected to the side wall of the first support column.

[0007] Through the above technical solution, by setting up a storage hopper and a material distribution mechanism connected to the bottom of the storage hopper, quantitative storage of raw materials can be achieved. The opening and closing of the first and second closing plates can effectively adjust the feeding rate. Through the cooperation between the two, the production flexibility of the feeding mechanism is improved. By turning the handle, the first bevel gear is driven to rotate. Through the meshing transmission between the gears, the second bevel gear starts to rotate, driving the threaded rod to rotate. Through the threaded transmission, the second support column begins to move upward.

[0008] Furthermore, the lifting and adjusting mechanism includes a threaded rod, a threaded hole at the top of the second support column, the threaded rod being inserted into the threaded hole and rotatably connected to the second support column, a rotating column fixedly connected to the top of the threaded rod, a second bevel gear fixedly connected to the top of the rotating column, a first limiting ring and a second limiting ring fixedly connected to the outer wall of the rotating column, a support plate being provided between the first limiting ring and the second limiting ring, the two end sidewalls of the support plate being fixedly connected to the inner walls of the two sides of the first support column respectively, the support plate being rotatably connected to the rotating column, a rotating rod being provided at the top of the second bevel gear, one end of the rotating rod being rotatably connected to the inner wall of one side of the first support column, the other end of the rotating rod penetrating the other side wall of the first support column and being fixedly connected to a handle, a first bevel gear being fixedly connected to the outer wall of the rotating rod, the first bevel gear meshing with the second bevel gear.

[0009] With the above technical solution, after the handle is turned, the rotating rod is driven to rotate. The first bevel gear fixedly connected to the outer wall of the rotating rod drives the second bevel gear to rotate. Then the rotating column starts to drive the threaded rod to rotate. Through the threaded transmission, the threaded rod starts to move upward. Under the clamping of the first limit ring and the second limit ring, the support plate starts to move upward. At the same time as the support plate moves upward, it drives the first support column to move upward, thereby realizing the lifting of the storage hopper and the material distribution mechanism.

[0010] Furthermore, limiting protrusions are fixedly connected to the inner walls on both sides of the first support column, and limiting grooves are formed on the outer walls on both sides of the second support column, with the limiting protrusions corresponding to the limiting grooves.

[0011] Through the above technical solution, the mutual engagement of the limiting protrusion and the limiting groove realizes the sliding connection between the first support column and the second support column.

[0012] Furthermore, the material distribution mechanism includes a material distribution box, the top of which is fixedly connected to the bottom of the storage hopper. A first limiting plate and a second limiting plate are fixedly connected to the inner walls on both sides of the bottom of the material distribution box, respectively. The first limiting plate and the second limiting plate are arranged in parallel and symmetrically. A first closing plate and a second closing plate are slidably connected between the first limiting plate and the second limiting plate.

[0013] Furthermore, a first limiting rack is fixedly connected to the end of the first closing plate away from the second closing plate, and a second limiting rack is fixedly connected to the end of the second closing plate away from the first closing plate. A connecting box is fixedly connected to the outer wall of the material distribution box near the first limiting rack. A rotating shaft is provided inside the connecting box. The top end of the rotating shaft passes through the top wall of the connecting box and is fixedly connected to a rotating cap. A drive gear is fixedly connected to the bottom end of the rotating shaft. The drive gear is rotatably connected to the first limiting rack and the second limiting rack.

[0014] With the above technical solution, when the rotating cap rotates, the rotating shaft starts to drive the drive gear to rotate. Through the meshing relationship between the drive gear and the first and second limiting racks, the first and second limiting racks start to move, and drive the first and second closing plates to move linearly along the gap between the first and second limiting plates, thereby realizing the feeding function of the material distribution mechanism. The feeding rate can be adjusted by changing the distance between the first and second closing plates.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model achieves quantitative storage of raw materials by setting up a storage hopper and a distributing mechanism connected to the bottom of the storage hopper. The opening and closing of the first and second closing plates effectively adjust the feeding rate. Through the cooperation between the two, the production flexibility of the feeding mechanism is improved. The feeding rate of the feeding mechanism can be adjusted according to actual production needs. By turning the handle, the first bevel gear is driven to rotate. Through the meshing transmission between the gears, the second bevel gear starts to rotate, driving the threaded rod to rotate. Through the threaded transmission, the third support column begins to move upward, thereby lifting the storage hopper and the distributing mechanism, fully meeting the feeding needs of injection molding machine feed hoppers of different heights.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figure 1 — Figure 7 As shown, a high-efficiency material feeding and buffering device for an injection molding machine used in automotive parts production includes an injection molding machine inlet 1, a storage hopper 6 at the top of the inlet 1, a support arm 5 fixedly connected to the top of the storage hopper 6, and a material distribution mechanism 7 fixedly connected to the bottom of the storage hopper 6. The material distribution mechanism 7 includes a material distribution box 701, the top of which is fixedly connected to the bottom of the storage hopper 6. A first limiting plate 711 and a second limiting plate 712 are fixedly connected to the inner walls on both sides of the bottom of the material distribution box 701, respectively. The first limiting plate 711 and the second limiting plate 712 are arranged in parallel and symmetrically. A first closing plate 709 is slidably connected between the first limiting plate 711 and the second limiting plate 712. The first closing plate 709 is fixedly connected to a first limiting rack 706 at one end away from the second closing plate 710, and a second limiting rack 707 is fixedly connected to the other end of the second closing plate 710 away from the first closing plate 709. A connecting box 702 is fixedly connected to the outer wall of the material distribution box 701 near the first limiting rack 706. A rotating shaft 703 is provided inside the connecting box 702. The top end of the rotating shaft 703 passes through the top wall of the connecting box 702 and is fixedly connected to a rotating cap 704. A driving gear 705 is fixedly connected to the bottom end of the rotating shaft 703. The driving gear 705 is rotatably connected to the first limiting rack 706 and the second limiting rack 707.

[0027] When the rotating cap 704 rotates, the rotating shaft 703 starts to drive the drive gear 705 to rotate. Through the meshing relationship between the drive gear 705 and the first limiting rack 706 and the second limiting rack 707, the first limiting rack 706 and the second limiting rack 707 start to move, and drive the first closing plate 709 and the second closing plate 710 to make linear movements in opposite directions or back directions along the gap between the first limiting plate 711 and the second limiting plate 712. This realizes the opening and closing of the material distribution mechanism 7, and thus realizes the material feeding function of the material distribution mechanism 7. The feeding rate can be adjusted by changing the distance between the first closing plate 709 and the second closing plate 710.

[0028] The first support column 3 is fixedly connected to both ends of the support arm 5. The second support column 2 is slidably connected to the bottom end of the first support column 3. The roller 4 is movably connected to the bottom end of the second support column 2. The lifting adjustment mechanism 8 is provided at the top of the second support column 2. The lifting adjustment mechanism 8 passes through the side wall of the first support column 3 and is rotatably connected to the side wall of the first support column 3.

[0029] The lifting and adjusting mechanism 8 includes a threaded rod 808. A threaded hole 809 is provided at the top of the second support column 2. The threaded rod 808 is inserted into the threaded hole 809 and rotatably connected to the second support column 2. A rotating column 805 is fixedly connected to the top of the threaded rod 808. A second bevel gear 803 is fixedly connected to the top of the rotating column 805. A first limiting ring 810 and a second limiting ring 811 are fixedly connected to the outer wall of the rotating column 805. A support plate 80 is provided between the first limiting ring 810 and the second limiting ring 811. 4. The two side walls of the support plate 804 are fixedly connected to the inner walls of the two sides of the first support column 3 respectively. The support plate 804 is rotatably connected to the rotating column 805. The top of the second bevel gear 803 is provided with a rotating rod 801. One end of the rotating rod 801 is rotatably connected to the inner wall of one side of the first support column 3. The other end of the rotating rod 801 passes through the other side wall of the first support column 3 and is fixedly connected to a handle 9. The outer wall of the rotating rod 801 is fixedly connected to the first bevel gear 802. The first bevel gear 802 meshes with the second bevel gear 803.

[0030] When the handle 9 is turned, it drives the rotating rod 801 to rotate. The first bevel gear 802, which is fixedly connected to the outer wall of the rotating rod 801, drives the second bevel gear 803 to rotate. Then, the rotating column 805 starts to drive the threaded rod 808 to rotate. Through the threaded transmission, the threaded rod 808 starts to move upward. Under the clamping of the first limit ring 810 and the second limit ring 811, the support plate 804 starts to move upward. At the same time as the support plate 804 moves upward, it drives the first support column 3 to move upward, thereby realizing the lifting of the storage hopper 6 and the material distribution mechanism 7.

[0031] Limiting protrusions 806 are fixedly connected to the inner walls on both sides of the first support column 3, and limiting grooves 807 are opened on the outer walls on both sides of the second support column 2. The limiting protrusions 806 and the limiting grooves 807 correspond to each other. The sliding connection between the first support column 3 and the second support column 2 is realized by the mutual engagement of the limiting protrusions 806 and the limiting grooves 807.

[0032] In use, the device is first positioned so that the material distribution mechanism 7 is above the injection molding machine inlet 1. When the height of the material distribution mechanism 7 needs to be increased, the handle 9 can be rotated. Through the meshing transmission of the first bevel gear 802 and the second bevel gear 803, the threaded rod 808 begins to move upward, thereby driving the support plate 804 and the first support column 3 to move upward. After the position is adjusted, the raw material is put into the storage hopper 6. By rotating the rotating cap 704, the rotating shaft 703 begins to drive the drive gear 705 to rotate, thereby the first limiting rack 706 and the second limiting rack 707 begin to drive the first closing plate 709 and the second closing plate 710 to move in opposite or opposite directions in a straight line, thereby realizing the opening and closing of the material distribution mechanism 7, and thus completing the adjustment of the feeding rate.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
