Description

Technical Field

[0001] This utility model relates to the field of television parts manufacturing technology, and in particular to a buffer unloading device for PS television back cover. Background Technology

[0002] In the manufacturing process of PS TV back covers, injection molding is one of the key steps. As a thin-walled plastic product, PS TV back covers have high requirements for shape precision and surface quality. Molten PS material is injected into the mold cavity through an injection molding machine, and after cooling and solidification, it forms a product that meets the specifications. After injection molding, the molded PS TV back cover needs to be smoothly removed from the injection molding machine to the subsequent processing or storage area. In this process, how to avoid damage to the product due to force and collision directly affects the product qualification rate and production efficiency. Therefore, designing a special material discharge buffer device for PS TV back covers has important practical significance.

[0003] In existing technology, after the injection molding machine completes the injection molding of the PS TV back cover, the product is usually removed from the cavity by the opening and closing of the mold. Then, the product falls directly onto the worktable or conveyor platform below the injection molding machine under gravity. Some production lines have a simple receiving plate below the injection molding machine's discharge port. This receiving plate is usually made of rigid metal and its only function is to catch the falling product and prevent it from falling directly to the ground. The entire process relies mainly on gravity for product transfer, without any dedicated cushioning structure for the impact force during the product's fall. Attempts to reduce impact are made only by adjusting the vertical distance between the worktable and the discharge port; the principle is relatively simple.

[0004] However, in the existing technology, during the process of PS TV back covers falling from the injection molding machine outlet to the receiving plate or worktable, due to the lack of an effective receiving and buffering structure, the product will directly impact the rigid receiving surface. In particular, the edges and surfaces of the product are prone to scratches, dents, or even cracks due to the impact, resulting in an increased product defect rate. This cannot meet the strict requirements of PS TV back covers for appearance and structural integrity. Therefore, a buffer material dropping device for PS TV back covers is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a buffer unloading device for PS TV back covers, which aims to improve the problem of damage and increased product defect rate caused by the PS TV back covers colliding with the worktable when falling from the injection molding machine outlet in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a buffer material feeding device for a PS TV back cover, comprising an injection molding machine, wherein the injection molding machine has an internal discharge port and a material receiving component is provided at the bottom of the injection molding machine; The receiving assembly includes a fixed frame located below the discharge port. A support frame is fixedly connected to one side of the fixed frame, and a receiving plate is fixedly connected to the top of the support frame. An inclined slide is provided on one side of the fixed frame, with one end fixedly connected to the side wall of the fixed frame and the other end fixedly connected to the side wall of the receiving plate.

A support plate is fixedly connected to the inner wall of the support frame, and a buffer assembly is provided on the top of the support plate.

[0007] The above technical solution achieves the effect of orderly material conveying and feeding.

[0008] Preferably, the buffer assembly includes multiple connecting columns and sliding columns, with the bottom ends of the multiple connecting columns fixedly connected to the upper surface of the support plate, and the multiple sliding columns slidably connected inside the multiple connecting columns.

[0009] The above technical solution achieves the effect of elastic support.

[0010] Preferably, each of the multiple connecting columns is fitted with a spring, one end of each spring is fixedly connected to the bottom of the inclined slide, and the other end is fixedly connected to the top of the support plate.

[0011] The above technical solution effectively absorbs the impact force transmitted by the sliding of the rear shell.

[0012] Preferably, a fixed seat is fixedly connected to the top of the support plate, and a buffer shaft is rotatably connected inside the fixed seat.

[0013] The above technical solution achieves the effect of assisting in the dispersion of pressure.

[0014] Preferably, one end of the buffer shaft is rotatably connected to a connecting seat, and one side of the connecting seat is fixedly connected to the bottom of the inclined slide.

[0015] The above technical solutions achieve the effect of optimizing force transmission and connection.

[0016] Preferably, the top of the receiving plate is fixedly connected to symmetrical limiting plates, and buffer plates are slidably connected inside each of the multiple limiting plates.

[0017] The above technical solution achieves the effect of guiding and restricting the back shell.

[0018] Preferably, a protective plate is fixedly connected to one side of each of the multiple buffer plates, and multiple springs are provided inside each of the multiple limiting plates.

[0019] The above technical solution achieves the effect of absorbing lateral impact and protecting the back shell.

[0020] Preferably, one end of each of the multiple springs is fixedly connected to the inner wall of the limiting plate, and the other end is fixedly connected to the side wall of the buffer plate.

[0021] The above technical solution achieves a stable connection and converts lateral impact force into elastic potential energy.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by setting an inclined slide at the discharge port of the injection molding machine, a feeding path is provided for the workpiece, and shock-absorbing buffer strips are equipped on the inclined slide track to initially buffer the workpiece, prevent its surface from being scratched, and prevent it from falling and being damaged, thereby achieving the effect of orderly feeding. This solves the problem of messy product positions and easy accumulation in the traditional dropping method, and improves the continuity and efficiency of the production process.

[0023] 2. In this utility model, the elastic deformation of spring one further absorbs the impact force, the protective plate prevents the workpiece from slipping to the ground, and spring two further provides elastic support for the workpiece, thereby achieving the effect of elastic protection for the TV back cover, solving the problem of damage caused by direct impact between the TV back cover and the worktable, and improving the product qualification rate.

[0025] Reference Figure 1 - Figure 3The present invention provides an embodiment of a buffer unloading device for a PS TV back cover, including an injection molding machine 1. The injection molding machine 1 has an outlet 2 inside, which corresponds to the mold cavity of the injection molding machine 1. When the mold is completed and opened, the formed PS TV back cover can be smoothly discharged through the outlet 2. The bottom of the injection molding machine 1 is provided with a receiving component for receiving the back cover sent from the outlet 2 and realizing buffer protection. The receiving assembly includes a fixing frame 4, which has an overall frame structure and is fixed to the ground directly below the discharge port 2 by bolts, providing stable support for the entire receiving assembly. The fixing frame 4 is located below the discharge port 2, and a support frame 3 is fixedly connected to one side of the fixing frame 4. A receiving plate 7 is fixedly connected to the top of the support frame 3. The receiving plate 7 is a horizontally placed flat plate structure used to receive the PS TV back cover after being cushioned and sliding down.

[0026] An inclined slide 5 is provided on one side of the fixed frame 4. The inclined slide 5 is a long, sloping structure. Its high end is fixedly connected to the side wall of the fixed frame 4 by welding and is aligned with the outlet end of the discharge port 2. The other end is also fixedly connected to the side wall edge of the receiving plate 7 by welding, forming a continuous sliding channel from the discharge port 2 to the receiving plate 7. One end of the inclined slide 5 is fixedly connected to the side wall of the fixed frame 4, and the other end is fixedly connected to the side wall of the receiving plate 7. Multiple shock-absorbing buffer strips 6 are fixedly connected to the side wall of the inclined slide 5. These shock-absorbing buffer strips 6 are evenly distributed along the length of the slide and protrude slightly towards the inside of the slide. They can contact the edge of the PS TV back cover during the slide and form multi-point buffer. All the shock-absorbing buffer strips 6 are made of rubber. A support plate 8 is fixedly connected to the inner wall of the support frame 3. A buffer component is provided on the top of the support plate 8 to provide shock absorption support for the entire inclined slide 5. Reference Figure 4 and Figure 5 The buffer assembly includes multiple connecting columns 9 and sliding columns 10. The multiple connecting columns 9 are evenly distributed, and their bottom ends are fixedly connected to the upper surface of the support plate 8 by welding. Each of them has a sliding cavity adapted to the sliding column 10. The bottom ends of the multiple connecting columns 9 are fixedly connected to the upper surface of the support plate 8. The multiple sliding columns 10 are slidably connected inside the multiple connecting columns 9 and can slide up and down with the force changes of the inclined slide 5. The outer wall of each of the multiple connecting columns 9 is fitted with a spring 11. When the multiple springs 11 are in their natural state, they can support the inclined slide 5 to maintain a preset tilt angle. When the inclined slide 5 is subjected to the pressure of the PS TV back cover, the springs 11 will be compressed as the sliding column 10 moves down, forming an elastic buffer for the slide. One end of each of the multiple springs 11 is fixedly connected to the bottom of the inclined slide 5, and the other end is fixedly connected to the top of the support plate 8.

[0027] A fixed base 12 is fixedly connected to the top of the support plate 8. A buffer shaft 13 is rotatably connected inside the fixed base 12. The buffer shaft 13 can rotate around the fixed base 12 and work with the spring 11 to disperse the impact force on the slide. A connecting base 14 is rotatably connected to one end of the buffer shaft 13. One side of the connecting base 14 is fixedly connected to the bottom of the inclined slide 5. A symmetrical limiting plate 15 is fixedly connected to the top of the receiving plate 7. The limiting plate 15 has a vertically upward plate structure and is used to prevent the PS TV back cover from sliding out of the receiving plate 7. Buffer plates 16 are slidably connected inside the multiple limiting plates 15.

[0028] Each of the multiple buffer plates 16 has a protective plate 17 fixedly connected to one side. Each of the multiple limiting plates 15 has multiple springs 18 inside. When the PS TV back cover slides to the receiving plate 7 and contacts the protective plate 17, the springs 18 will further absorb the impact force through the sliding of the buffer plate 16, preventing the back cover from directly colliding with the limiting plate 15. One end of each of the multiple springs 18 is fixedly connected to the inner wall of the limiting plate 15, and the other end is fixedly connected to the side wall of the buffer plate 16.

[0029] Working principle: When using the buffer unloading device for the PS TV back cover, the PS TV back cover is injection molded by the injection molding machine 1. The injection-molded PS TV back cover is then ejected from the discharge port 2 and falls onto the inclined slide 5 located at the discharge port 2. It then slides down the inclined slide 5. During the descent, the shock-absorbing buffer strip 6 on the inclined slide 5 can buffer the PS TV back cover, reducing the impact and friction between it and the track. At the same time, the spring 11 under the fixing frame 4 will elastically deform as the fixing frame 4 is subjected to force, further absorbing the PS TV back cover. The impact force generated when the back cover slides down achieves the purpose of double buffering and shock absorption, preventing the PS TV back cover from being directly damaged by collision with the worktable. When the TV back cover slides to the surface of the receiving plate 7, the limiting plates 15 on both sides of the receiving plate 7 can prevent the TV back cover from falling to the ground, and the protective plate 17 can prevent the TV back cover from being damaged by collision. When the TV back cover collides with the protective plate 17, it will compress the second spring 18, causing the second spring 18 to undergo elastic deformation, providing elastic limiting guidance for the TV back cover, thereby further ensuring the stability of the TV back cover during the unloading process.
