Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically an injection molding device for automotive parts manufacturing that facilitates material feeding. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve it. They broadly cover multiple areas such as engine systems, transmission systems, braking systems, steering systems, and electrical equipment. Engine parts include pistons, crankshafts, and valves, which provide power for vehicle operation; the clutch and transmission of the transmission system ensure efficient power transmission; the brake pads and brake discs of the braking system are related to driving safety; the steering gear and tie rods of the steering system determine the precision of handling; the batteries and generators of the electrical equipment provide power to various parts of the vehicle. In addition, accessories such as interior, exterior, and body parts, such as seats, bumpers, and windshield wipers, not only enhance the driving experience but also ensure the car's aesthetics and functional diversity. The quality and performance of these parts have a direct impact on the safety, comfort, and reliability of the car, and are an important support for the normal operation and development of the vehicle.

[0003] A search revealed that Chinese Patent Publication No. CN112895286A discloses an easy-to-use injection molding process production device for automotive parts injection molds. Although it has automatic demolding and material discharge functions, during the demolding process, due to the tight bonding between some automotive parts and the mold block during injection molding, coupled with unreasonable mold surface roughness, demolding angle design, and other factors such as thermal expansion and contraction, the device has a certain probability of causing plastic products to stick to the mold block. This not only leads to demolding failure and reduced production efficiency, but may also cause damage to the automotive parts and mold due to forced demolding, increasing subsequent maintenance costs.

When injection molding is completed and the demolding process begins, the servo motor starts, driving the rotating rod to rotate. The stop block rotates accordingly and pushes the movable plate. While the movable plate compresses the second spring, the movable rod slides in the movable groove. This process causes the mold core and the mold closing core to separate. This ingenious structural design uses mechanical force to initially separate the automotive parts from the mold core in the initial stage of demolding, breaking the possible tight fit between the two. This greatly reduces the probability of automotive parts sticking to the mold block, improves the demolding success rate, avoids production interruptions due to demolding failure, and ensures production efficiency.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 4 In this embodiment of the present invention, an injection molding device for the production of automotive parts that facilitates material unloading includes: a desktop 1, which serves as the basic support platform for the entire device. Four sets of support legs 24 are symmetrically fixed at four ends below the desktop 1, providing stable support for the device. Side plates 2 are symmetrically fixed on both sides above the desktop 1, which not only serve as a connection but also provide installation positions for two sets of guide rods 3. The guide rods 3 are slidably connected to a power plate 4. The power plate 4 has two sets of guide holes on its side that are adapted to the guide rods 3, and is driven by hydraulic rods on its side.

[0022] During the injection molding operation, the hydraulic rod extends, and the resulting thrust drives the power plate 4 to move linearly along the guide rod 3. Since the side of the power plate 4 has a guide hole that matches the guide rod 3, the stability of its movement is ensured. When the power plate 4 moves, it drives the assembly module 5 fixed to one side to move synchronously until the assembly module 5 and the mold block 12 are tightly fitted together to form a closed injection molding cavity, which is ready for the injection molding process. The assembly module 5 has a mold core 6 fixed inside, while the mold core 13 is movably connected to the inside of the mold block 12, which together form the space for injection molding.

[0023] Once the mold is closed, molten high-temperature injection material is injected into the molding groove formed by the mold core 6 and the mold core 13 through the injection port 20 above the mold assembly module 5. Over time, the injection material gradually cools and solidifies within the molding groove, ultimately forming the desired shape of the automotive part.

[0024] After injection molding is completed, the demolding process begins. A servo motor is installed above the mold block 12. The rotating rod 18 and the stop block 19 are mounted on the back of the movable plate 15, and the rotating rod 18 is driven by the servo motor. First, the servo motor above the mold block 12 is started. The servo motor converts electrical energy into mechanical energy, driving the rotating rod 18 to rotate in a circular motion. The stop block 19, which is fixed to the side of the rotating rod 18, rotates accordingly. During the rotation, the stop block 19 contacts the movable plate 15 and continuously applies a pushing force, causing the movable plate 15 to compress the second spring 14.

[0025] During this process, the movable rod 17 slides relative to the movable groove 16, driving the mold core 13 to move away from the mold closing core 6, thus achieving the initial separation of the automotive parts from the mold core 13. A second spring 14 is fixedly connected to the back of the mold core 13, and a movable plate 15 is fixedly connected to the side of the second spring 14. A movable groove 16 is opened at the center of the second spring 14 on the back of the mold core 13, and a movable rod 17 is fixedly connected to the side of the movable plate 15. The cooperation of these components realizes the separation action of the mold core 13.

[0026] After the separation of mold core 13 is completed, the hydraulic rod begins to retract. The retraction force of the hydraulic rod pulls the power plate 4, causing it to slide in the opposite direction away from mold block 12 along the guide rod 3, thereby separating the assembly module 5 from mold block 12. During the reverse sliding process of the power plate 4, a first spring 7 is fixedly connected to its back. The movable block 8 fixedly connected to the side of the first spring 7 moves synchronously with the power plate 4, gradually approaching the top block 11. The top block 11 is fixedly connected to the side of a set of side plates 2 located on the back of the power plate 4. When the movable block 8 contacts the top block 11, the top block 11 blocks the movable block 8, restricting its movement. Continuing forward, the power plate 4 continues to move backward under the continuous pull of the hydraulic rod. This causes the movable block 8 to push the ejector rod 10, so that the ejector rod 10 overcomes the elastic force of the first spring 7 and extends out of the ejector groove 9. The ejector groove 9 is opened at the center of the first spring 7 on the other side of the power plate 4. The ejector rod 10 is fixedly connected to the side of the movable block 8. The ejector groove 9 is adapted to the ejector rod 10, and the ejector groove 9 extends through to the forming groove inside the mold core 6. After the ejector rod 10 extends out, it directly pushes against the automotive parts in the forming groove, causing the automotive parts to separate from the mold core 6, thus completing the entire demolding process.

[0027] After demolding, the car parts slide into the inclined groove 21 above the table 1 under the action of gravity. The inclined groove 21 is connected to the discharge port 22 opened at the center of the table 1. Then, it slides down the slope of the inclined groove 21 to the discharge port 22. Through the discharge port 22, the car parts fall into the receiving cart 23 below, realizing the discharge and collection for subsequent transportation and processing.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The working principle of this utility model is as follows: The hydraulic rod extends upon activation, pushing the power plate 4 with thrust. Because the power plate 4 has a guide hole on its side that matches the guide rod 3, it can move smoothly in a straight line along the guide rod 3, driving the assembly module 5 fixed to one side until the assembly module 5 and the mold block 12 are tightly fitted together, forming an injection cavity. Then, high-temperature molten injection material is injected through the injection port 20 above the assembly module 5. The material cools and solidifies in the molding groove formed by the mold core 6 and the mold core 13, forming an automotive part. After injection molding is completed, the servo motor above the mold block 12 is activated. The servo motor drives the rotating rod 18 to rotate, and the abutment block 19 on the side of the rotating rod 18 rotates accordingly. The abutment block 19 pushes the movable plate 15 to compress the second spring 14, and the movable rod 17 moves in the movable groove. The 16 slides inward, causing the mold core 13 to separate from the mold closing core 6; then the hydraulic rod retracts, pulling the power plate 4 to slide in the opposite direction along the guide rod 3, causing the mold closing module 5 to separate from the mold block 12. During this process, the movable block 8 on the back of the power plate 4 moves synchronously with it and approaches the top block 11. When the movable block 8 is blocked from contacting the top block 11, while the power plate 4 is still pulled backward by the hydraulic rod, the movable block 8 pushes the ejector rod 10 to overcome the elastic force of the first spring 7, and extends out from the ejector groove 9, pushing the automotive part in the molding groove, so that it separates from the mold closing core 6; after demolding, the automotive part slides into the inclined groove 21 above the table 1 under the action of gravity, slides down the inclined groove 21 to the material outlet 22, and falls into the receiving cart 23 below through the material outlet 22, completing the entire injection molding production process.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
