Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically to an injection molding device for automotive interior trim. Background Technology

[0002] With the continuous development of the automotive industry, the quality and production efficiency of automotive interiors have had a significant impact on the overall performance and market competitiveness of automobiles. Injection molding of automotive interiors is one of the key steps in the production process. It involves injecting molten plastic raw materials into a mold, which then cools and solidifies to produce various automotive interior parts, such as dashboards, door panels, and seat backs.

[0003] Traditional injection molding machines involve a cumbersome demolding process after injection molding, requiring manual operation. This is not only inefficient but also prone to damaging the molded parts. Furthermore, quality inspection of the molded parts typically needs to be performed separately after injection molding, increasing production costs and time.

[0004] Therefore, an injection molding device for automotive interiors is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an injection molding device for automotive interiors in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An injection molding apparatus for automotive interior trim includes a frame, a fixed mold and a movable mold disposed on the top of the frame, a movement control mechanism for driving the movable mold to move laterally is installed on the left side of the top surface of the frame, an injection tube is fixedly inserted into the surface of the fixed mold, a tilt control component for controlling the rotation of the fixed mold is installed on the right side of the top surface of the frame, a screening component is disposed in the middle of the top surface of the frame, and an ejection mechanism is disposed on the right side wall of the fixed mold.

[0008] Furthermore, the motion control mechanism includes a support base, which is fixedly connected to the top surface of the frame. A first electric push rod is fixedly installed on the right side of the support base. The telescopic end of the first electric push rod is fixedly connected to the movable mold. A sliding column is fixedly connected to the right side of the support base. A sleeve is slidably fitted onto the surface of the sliding column, and the end of the sleeve is fixedly connected to the movable mold.

[0009] Furthermore, the tilt control assembly includes a fixed base, which is fixedly connected to the top surface of the frame. A first motor is fixedly mounted on the front side of the fixed base, and a first rotating shaft is fixedly connected to the output end of the first motor. A support rod is fixedly sleeved on the surface of the first rotating shaft, and the end of the support rod is fixedly connected to the fixed mold.

[0010] Furthermore, the ejection mechanism includes a second electric push rod, which is fixedly installed on the bottom surface of the movable mold. A connecting rod is fixedly connected to the telescopic end of the second electric push rod, and an insert rod is fixedly connected to the end of the connecting rod, which is movably inserted into the fixed mold.

[0011] Furthermore, the screening component includes a mounting frame, which is fixedly connected to the center of the top surface of the frame. A second motor is fixedly mounted on the surface of the mounting frame, and a second rotating shaft is fixedly connected to the output end of the second motor. A support block is fixedly sleeved on the surface of the second rotating shaft. A mounting plate is fixedly connected to the top surface of the support block, and a weighing sensor is mounted on the surface of the mounting plate. Grooves are provided on both the front and back of the frame, and a receiving box is provided inside the groove.

[0012] Furthermore, there are four sliding pillars and four sleeves, and the four sliding pillars and four sleeves are located at the four corners of the left side of the movable mold.

[0013] The beneficial effects of this utility model are as follows:

[0014] The movable mold is driven by a motion control mechanism to close the gap between the fixed mold and the movable mold. Molten plastic material is then introduced into the fixed mold through an injection tube. The injection molded part cools and solidifies inside both the fixed and movable molds. After solidification, the movable mold is driven by the motion control mechanism to move away from the fixed mold. The fixed mold is then rotated to the left and moved closer to the screening component by a tilt control component. The ejection mechanism helps remove the injection molded part from the fixed mold. The injection molded part will fall onto the surface of the screening component. The screening component detects whether the weight of the injection molded part meets the standard and separates qualified and defective products into two directions for unloading. This invention achieves the effect of automatic demolding of injection molded parts, making the unloading of injection molded parts more convenient. It can also automatically detect and classify injection molded parts according to weight, further improving processing efficiency. Attached Figure Description

[0024] like Figures 1 to 3As shown, an automotive interior injection molding device includes a frame 1. A fixed mold 2 and a movable mold 3 are disposed on the top of the frame 1. A movement control mechanism 4 for driving the movable mold 3 to move laterally is installed on the left side of the top surface of the frame 1. The movement control mechanism 4 includes a support base 401, which is fixedly connected to the top surface of the frame 1. A first electric push rod 402 is fixedly installed on the right side of the support base 401. The telescopic end of the first electric push rod 402 is fixedly connected to the movable mold 3. A sliding column 404 is fixedly connected to the right side of the support base 401. A sleeve 403 is slidably sleeved on the surface of the sliding column 404, and the end of the sleeve 403 is fixedly connected to the movable mold 3. It should be noted that by operating the first electric push rod 402, the movable mold 3 can be driven to move, causing the movable mold 3 to disengage from the fixed mold 2, facilitating the demolding of subsequent automotive interior injection molded parts. When the movable mold 3 moves, it will drive the sleeve 403 to slide along the surface of the sliding column 404, making the movement of the movable mold 3 more stable.

[0025] There are four sliding pillars 404 and four sleeves 403, and the four sliding pillars 404 and four sleeves 403 are located at the four corners of the left side of the movable mold 3. It should be noted that by setting four sliding pillars 404 and four sleeves 403, the movable mold 3 is stably supported.

[0026] An injection tube 5 is fixedly inserted into the surface of the fixed mold 2. A tilt control assembly 6 for controlling the rotation of the fixed mold 2 is installed on the right side of the top surface of the frame 1. The tilt control assembly 6 includes a fixed base 601, which is fixedly connected to the top surface of the frame 1. A first motor 602 is fixedly installed on the front of the fixed base 601. A first rotating shaft 603 is fixedly connected to the output end of the first motor 602. A support rod 604 is fixedly sleeved on the surface of the first rotating shaft 603, and the end of the support rod 604 is fixedly connected to the fixed mold 2. More specifically, by operating the first motor 602, the first rotating shaft 603 is driven to rotate, which in turn drives the support rod 604 to rotate, causing the fixed mold 2 to tilt to the left, making it easier for the automotive interior injection molded parts to fall into the screening assembly 8.

[0027] A screening component 8 is provided in the middle of the top surface of the frame 1. The screening component 8 includes a mounting frame 801, which is fixedly connected to the middle of the top surface of the frame 1. A second motor 802 is fixedly mounted on the surface of the mounting frame 801. A second rotating shaft 803 is fixedly connected to the output end of the second motor 802. A support block 804 is fixedly sleeved on the surface of the second rotating shaft 803. A mounting plate 805 is fixedly connected to the top surface of the support block 804. A weighing sensor 806 is mounted on the surface of the mounting plate 805. Grooves are provided on both the front and back of the frame 1, and a receiving box 807 is provided inside the groove. More specifically, when the automotive interior injection molded parts fall onto the surface of the weighing sensor 806, the weighing sensor 806 can measure their weight. The second motor 802 then drives the second rotating shaft 803 to rotate, thereby causing the support block 804 and the mounting plate 805 to rotate. This allows the injection molded parts on the surface of the mounting plate 805 to slide off. In actual use, when the detected weight exceeds the preset range, the second motor 802 can be controlled to drive the second rotating shaft 803 to change direction via a PLC controller or other conventional equipment. This causes the mounting plate 805 to rotate in different directions, thereby conveying qualified products and defective products to the front or rear receiving box 807 respectively.

[0028] An ejection mechanism 7 is provided on the right side wall of the fixed mold 2. The ejection mechanism 7 includes a second electric push rod 701, which is fixedly installed on the bottom surface of the movable mold 3. A connecting rod 702 is fixedly connected to the telescopic end of the second electric push rod 701, and an insert rod 703 is fixedly connected to the end of the connecting rod 702. The insert rod 703 is movably inserted into the fixed mold 2. It should be noted that after the plastic part cools and solidifies, the operation of the second electric push rod 701 can drive the connecting rod 702 to move, thereby pushing the insert rod 703 to move, so that the injection molded part can be detached from the inside of the fixed mold 2.

[0029] In summary: The movable mold 3 is moved by the motion control mechanism 4, causing the fixed mold 2 and the movable mold 3 to close. Molten plastic raw material is introduced into the fixed mold 2 through the injection tube 5. The injection molded part then cools and solidifies inside the fixed mold 2 and the movable mold 3. After solidification, the movable mold 3 is moved away from the fixed mold 2 by the motion control mechanism 4. Then, the fixed mold 2 is rotated to the left and moved closer to the screening component 8 by the tilt control component 6. The ejection mechanism 7 helps to remove the injection molded part from the inside of the fixed mold 2. The injection molded part will fall on the surface of the screening component 8. The screening component 8 detects whether the weight of the injection molded part meets the standard and separates qualified and defective products into two directions for unloading. In use, this utility model achieves the effect of automatic demolding of injection molded parts, making the unloading of injection molded parts more convenient. It can also automatically detect and classify injection molded parts according to weight, further improving processing efficiency.
