Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to injection molds for automotive parts. Background Technology

[0002] In the injection molding process of automotive parts, the injection mold is a key molding equipment, and its performance directly affects product quality and production efficiency. Traditional automotive parts injection molds typically adopt a vertical opening and closing structure. During demolding, some complex automotive parts face significant demolding resistance within the mold cavity, easily leading to parts getting stuck inside the mold and difficult to remove. This not only increases demolding difficulty but may also damage the parts, affecting product yield. Furthermore, existing molds mostly require manual removal of parts after molding, which not only consumes a lot of manpower and reduces production efficiency but also poses certain safety hazards. At the same time, the material unloading process of traditional molds is not smooth enough, and parts are prone to accumulation and jamming during the descent, affecting the continuity of the production line.

[0003] Therefore, we propose injection molds for automotive parts. Utility Model Content

[0004] The main purpose of this utility model is to provide an injection mold for automotive parts. In order to prevent problems such as difficulty in demolding, damage to parts, low efficiency of manual part removal, safety hazards and material jamming in the injection molding production of automotive parts, thereby improving the product qualification rate, production efficiency and production line continuity, it can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An injection mold for automotive parts includes a base plate, with support columns fixedly connected to the four corners of the bottom end of the base plate. Symmetrical support plates are vertically fixedly connected to the two sides of the top of the base plate. A lower mold base is rotatably connected to the inner side of the two support plates via a rotating shaft. An upper mold base that can move up and down is provided on the top of the lower mold base. One end of each of the two rotating shafts is fixedly connected to the two sides of the lower mold base, and the other end of one of the rotating shafts passes through the support plate and is driven by a first transmission mechanism.

[0007] Both support plates are vertically provided with sliding grooves. The inner sides of the two support plates are provided with a material feed plate that moves up and down. The material feed plate is located directly below the lower mold base. The upper parts of both sides of the material feed plate are fixedly connected with movable plates. The ends of the two movable plates away from the material feed plate pass through the sliding grooves and are driven by the second transmission mechanism. The movable plates are slidably connected to the sliding grooves.

[0008] The bottom inner wall of the feeding plate is provided with an inclined surface, and the top of the bottom plate is fixedly installed with an inclined platform, which is located near the lower part of the inclined surface. A support frame is fixedly connected to the bottom end of the bottom plate near the inclined platform, and a receiving box is slidably installed on the support frame.

[0009] By adopting the above technical solution, the lower mold base is rotatably connected to the support plate through a rotating shaft. In the initial state, the upper mold base moves downward and closes with the lower mold base to form an injection cavity. Molten plastic is injected into the closed cavity through the gating system of the upper mold base. After pressure holding and cooling solidification, it forms automotive parts. After injection molding is completed, the upper mold base moves upward to open the mold, and the molded parts remain on the lower mold base.

[0010] The first transmission mechanism drives one of the rotating shafts to rotate, which can cause the lower mold base to rotate around the rotating shaft, making it easy to adjust the injection angle or demolding path. The second transmission mechanism drives the moving plate to slide up and down in the slide groove, causing the material plate to move upward to near the bottom of the lower mold base. When the part is ejected from the lower mold base and falls onto the material plate, the top of the material plate is provided with an inclined surface. The ejected part slides down the inclined surface to the inclined platform on the bottom plate, and then slides into the receiving box below. The receiving box is slidably installed on the support frame, which makes it easy to take out the collected parts periodically.

[0011] The first transmission mechanism controls the tilting angle of the lower mold base, which is used not only for tilted injection to avoid air bubbles and improve filling effect, but also to assist the parts in falling off during demolding by tilting; the second transmission mechanism drives the blanking plate to move up and down, realizing automatic ejection of parts, avoiding manual removal and improving production efficiency; the inclined plane and inclined platform use gravity to realize the automatic sliding of parts, reducing mechanical interference and improving the smoothness of blanking; the lower mold base angle is adjusted by the rotating shaft and the first transmission mechanism to adapt to the injection molding process requirements of complex parts and reduce demolding difficulty; the receiving box can be slidably disassembled, which is convenient for centralized collection and cleaning of parts and optimizes the production line layout.

[0012] Furthermore, the first transmission mechanism includes a transmission box fixedly installed on the upper part of the outer side of the two support plates, and the two transmission boxes are arranged symmetrically.

[0013] By adopting the above technical solution, the transmission box is used to protect the transmission components inside the box.

[0014] Furthermore, one end of one of the rotating shafts, away from the lower mold base, extends into the interior of the transmission box, and a worm gear is fixedly connected to the outer wall of the rotating shaft, while a worm gear meshing with the worm gear is connected to the inner wall of the transmission box.

[0015] By adopting the above technical solution, when the worm rotates, it drives the shaft to rotate through the meshing worm wheel, and the speed reduction and torque increase characteristics of the worm wheel transmission are used to achieve smooth driving or positioning of the lower mold base.

[0016] Furthermore, a first motor is fixedly installed on the outer wall of one end of the transmission box, and the output shaft of the first motor is coaxially connected to one end of the worm gear.

[0017] By adopting the above technical solution, after the first motor is powered on, the output shaft rotates, and through the coaxial connection, it directly drives the worm to rotate synchronously, providing a power source for the worm gear transmission mechanism, so that the rotating shaft can achieve deceleration and torque increase motion to drive the lower mold base.

[0018] Furthermore, the second transmission mechanism includes two threaded rods vertically rotatably connected to the base plate, a limiting plate is fixedly connected to the middle of the outer side wall of the two support plates, and the limiting plate is located directly above the slide groove, and the top end of the threaded rod is rotatably connected to the bottom end of the limiting plate.

[0019] By adopting the above technical solution, the limiting plate ensures that the rotational motion of the threaded rod is completely converted into the lifting and lowering of the moving plate, avoiding axial movement. The synchronous rotation of the two threaded rods ensures that the force on both sides of the feeding plate is balanced, achieving smooth lifting and lowering.

[0020] Furthermore, the outer side of the threaded rod is threadedly connected to the movable plate, and a second motor is fixedly installed at the bottom end of the base plate, with the output shaft of the second motor coaxially connected to the bottom end of the threaded rod.

[0021] By adopting the above technical solution, the second motor drives the threaded rod to rotate. Since the limiting plate only provides rotational support and restricts the movement of the moving plate, the moving plate cooperates with the threaded rod through the threaded pair. Under the guidance of the slide groove, the rotational motion is converted into linear motion, thereby realizing the lifting and lowering of the moving plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This utility model of automotive parts injection mold drives the rotating shaft to rotate through the first transmission mechanism, causing the lower mold base to rotate around the rotating shaft. It can flexibly adjust the injection angle according to the injection molding process requirements of different automotive parts. During the injection molding process, it can effectively avoid the generation of air bubbles, improve the plastic filling effect, and improve the product molding quality. During demolding, by tilting the lower mold base, gravity is used to assist the parts to fall off, which significantly reduces the demolding difficulty, reduces the risk of parts damage, and improves the product qualification rate.

[0024] This utility model relates to an injection mold for automotive parts. A second transmission mechanism drives a moving plate to slide within a groove, causing the unloading plate to move up and down, thus collecting the parts. When a part falls from the lower mold base onto the unloading plate, the inclined structure of the unloading plate and the inclined platform allows the part to automatically slide down into the receiving box by gravity, eliminating the need for manual intervention. This significantly improves production efficiency and reduces labor costs. Furthermore, the receiving box is slidable and detachable, facilitating the periodic removal of collected parts, optimizing the production line layout, and making the production process more convenient and efficient.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To prevent problems such as demolding difficulties, part damage, low efficiency of manual part removal, safety hazards, and material unloading jams in the injection molding production of automotive parts, thereby improving product qualification rate, production efficiency, and production line continuity, such as... Figure 1 , Figure 2 , Figure 3 As shown, an injection mold for automotive parts includes a base plate 1. Support columns 21 are fixedly connected to the four corners of the bottom end of the base plate 1. Symmetrical support plates 2 are vertically fixedly connected to the two sides of the top of the base plate 1. A lower mold base 12 is rotatably connected to the inner side of the two support plates 2 through a rotating shaft 3. An upper mold base 13 that moves up and down is provided on the top of the lower mold base 12. One end of the two rotating shafts 3 is fixedly connected to the two sides of the lower mold base 12 respectively. The other end of one of the rotating shafts 3 passes through the support plate 2 and is driven by a first transmission mechanism 4.

[0031] Both support plates 2 are vertically provided with sliding grooves 5. The inner sides of the two support plates 2 are provided with a material feed plate 6 that moves up and down. The material feed plate 6 is located directly below the lower mold base 12. The upper parts of both sides of the material feed plate 6 are fixedly connected with movable plates 7. The ends of the two movable plates 7 away from the material feed plate 6 pass through the sliding grooves 5 and are driven by the second transmission mechanism. The movable plates 7 are slidably connected to the sliding grooves 5.

[0032] The bottom inner wall of the feeding plate 6 is provided with an inclined surface 8. The top of the bottom plate 1 is fixedly installed with an inclined platform 9, and the inclined platform 9 is located near the lower part of the inclined surface 8. The bottom end of the bottom plate 1 near the inclined platform 9 is fixedly connected with a support frame 10, and a receiving box 11 is slidably installed on the support frame 10.

[0033] In use, the lower mold base 12 is rotatably connected to the support plate 2 via the rotating shaft 3. In the initial state, the upper mold base 13 moves downward and closes with the lower mold base 12 to form an injection cavity. Molten plastic is injected into the closed cavity through the gating system of the upper mold base 13. After pressure holding and cooling solidification, it forms automotive parts. After injection molding is completed, the upper mold base 13 moves upward to open the mold, and the molded parts remain on the lower mold base 12.

[0034] The first transmission mechanism 4 drives one of the rotating shafts 3 to rotate, which can cause the lower mold base 12 to rotate around the rotating shaft 3, making it easy to adjust the injection angle or demolding path. The second transmission mechanism drives the moving plate 7 to slide up and down in the slide groove 5, causing the unloading plate 6 to move upward to near the lower mold base 12. When the part is ejected from the lower mold base 12 and falls onto the unloading plate, the top of the unloading plate 6 is provided with an inclined surface 8. The ejected part slides down the inclined surface 8 to the inclined platform 9 on the base plate 1, and then slides into the receiving box 11 below via the inclined platform 9. The receiving box 11 is slidably installed on the support frame 10, making it easy to periodically take out the collected parts.

[0035] The first transmission mechanism 4 controls the tilting angle of the lower mold base 12, which is used not only for tilting injection to avoid air bubbles and improve filling effect, but also to assist the parts in falling off during demolding by tilting; the second transmission mechanism drives the material plate 6 to move up and down to realize the automatic ejection of parts, avoid manual removal of parts, and improve production efficiency; the inclined plane 8 and the inclined platform 9 use gravity to realize the automatic sliding of parts, reduce mechanical interference, and improve the smoothness of material feeding; the angle of the lower mold base is adjusted by the rotating shaft 3 and the first transmission mechanism 4 to adapt to the injection molding process requirements of complex parts and reduce the demolding difficulty; the receiving box 11 can be slidably disassembled to facilitate centralized collection and cleaning of parts and optimize the production line layout.

[0036] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes the first transmission mechanism 4, which includes a transmission box 14 fixedly installed on the upper part of the outer side of the two support plates 2, and the two transmission boxes 14 are arranged symmetrically.

[0037] In use, the transmission box 14 is used to protect the transmission components inside the box.

[0038] For example, such as Figure 1 , Figure 2As shown, the present invention also includes one of the rotating shafts 3, the end of which is away from the lower mold base 12 extends into the interior of the transmission box 14, and a worm gear 15 is fixedly connected to the outer wall of the rotating shaft 3, and a worm 16 that meshes with the worm gear 15 is connected to the inner wall of the transmission box 14.

[0039] When in use, the worm 16 rotates and drives the rotating shaft 3 to rotate through the meshing worm wheel 15. The speed reduction and torque increase characteristics of the worm wheel 15 and worm 16 transmission are used to achieve smooth driving or positioning of the lower mold base 12.

[0040] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a first motor 17 fixedly installed on the outer wall of one end of the transmission box 14, and the output shaft of the first motor 17 is coaxially connected to one end of the worm gear 16.

[0041] When in use, the first motor 17 is powered on and its output shaft rotates, which directly drives the worm gear 16 to rotate synchronously through a coaxial connection, providing a power source for the worm gear transmission mechanism, so that the rotating shaft 3 can achieve deceleration and torque increase motion to drive the lower mold base 12.

[0042] For example, such as Figure 1 As shown, the present invention also includes the second transmission mechanism comprising two threaded rods 19 vertically rotatably connected to the base plate 1, a limiting plate 18 fixedly connected to the middle of the outer side wall of the two support plates 2, and the limiting plate 18 being located directly above the slide groove 5, wherein the top end of the threaded rod 19 is rotatably connected to the bottom end of the limiting plate 18.

[0043] During use, the limiting plate 18 ensures that the rotational motion of the threaded rod 19 is completely converted into the lifting and lowering of the moving plate 7, avoiding axial movement. The double threaded rods 19 rotate synchronously to ensure that the force on both sides of the feeding plate 7 is balanced, achieving smooth lifting and lowering.

[0044] For example, such as Figure 1 As shown, the present invention also includes a threaded connection between the outer side of the threaded rod 19 and the movable plate 7, and a second motor 20 fixedly installed at the bottom end of the base plate 1, wherein the output shaft of the second motor 20 is coaxially connected to the bottom end of the threaded rod 19.

[0045] In use, the second motor 20 drives the threaded rod 19 to rotate. Since the limiting plate 18 only provides rotational support and restricts the movement of the moving plate 7, the moving plate 7 cooperates with the threaded rod through the threaded pair. Under the guidance of the slide groove 5, the rotational motion is converted into linear motion, thereby realizing the lifting and lowering of the moving plate 7.

[0046] It should be noted that this utility model is an injection mold for automotive parts. The lower mold base 12 is rotatably connected to the support plate 2 through the rotating shaft 3 and is in a horizontal position. The upper mold base 13 moves downward and closes with the lower mold base 12 to form an injection cavity. Molten plastic is injected into the closed cavity through the gating system of the upper mold base 13. After pressure holding, cooling and solidification, automotive parts are formed.

[0047] The upper mold base 13 moves upward to open the mold, and the molded part remains on the lower mold base 12. If tilting injection or demolding assistance is required, the first transmission mechanism 4 is activated, and the first motor 17 drives the worm gear 16 to rotate. The worm wheel 15 drives the rotating shaft 3 to rotate, so that the lower mold base 12 rotates around the rotating shaft 3 to the target angle. By utilizing the speed reduction and torque increase characteristics of the worm wheel and worm, smooth driving and positioning are achieved.

[0048] The second transmission mechanism is activated, and the second motor 20 drives the threaded rod 19 to rotate. The moving plate 7 slides upward in the slide groove 5, driving the unloading plate 6 to rise to near the lower mold base 12. The limiting plate 18 ensures that the rotational motion of the threaded rod 19 is converted into a smooth linear motion, preventing the unloading plate 6 from tilting. When the part is ejected from the lower mold base 12 and falls onto the unloading plate, the part slides down the inclined surface 8 at the top of the unloading plate 6. The part slides down the inclined surface 8 to the inclined platform 9 of the base plate 1, and then slides down the inclined platform 9 into the receiving box 11 below. The receiving box 11 can be slid out from the support frame 10 for easy periodic cleaning of the parts.

[0049] After the material is collected, the unloading plate 6 is reset to its initial position through the second transmission mechanism, and the lower mold base 12 can be rotated back to the horizontal position as needed to enter the next injection molding cycle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
