Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically a combined opening and closing injection molding device. Background Technology

[0002] Automotive combination switches are key components integrating multiple control functions. They are typically installed on the steering column below the steering wheel, consisting of left and right handles and buttons for convenient operation. Their core functions include lighting and light signal control. The left handle is used to adjust the turn signals, high and low beam headlights, and side marker lights. The right handle mainly controls the windshield wipers and washer fluid, allowing switching between stop, intermittent, and high / low speed modes. Pulling up or pressing the button sprays washer fluid. Some models also integrate horn and hazard warning light buttons. During operation, they use mechanical structures to open and close contacts or combine with electronic components to achieve complex controls, allowing the driver to operate them without significant physical movement, greatly improving driving safety and convenience. Injection molding is the core step in the manufacturing process of automotive combination switches, directly affecting product performance and reliability.

[0003] Currently, in the injection molding production of combination switches for automobiles, after injection molding, once the part has cooled to a certain degree, it is ejected. Then, mechanical clamps are used to hold and transport the part. However, the part is not completely cooled at this time and still retains a high residual heat. The surface of the part may still be slightly softened at high temperature. When the clamp comes into contact with the surface of the part, if the force applied by the clamp is uneven, it can easily damage the contact surface between the part and the clamp, causing indentations and scratches, which affect the appearance of the part. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a combined opening and closing molding device, which solves the problem that the molded part is not completely cooled at this time and still has high residual heat. The surface of the molded part may still be slightly soft at high temperature. When the clamp comes into contact with the surface of the molded part, if the clamp is not subjected to uneven force when gripping, it is easy to damage the contact surface between the molded part and the clamp, resulting in indentations and scratches, which affect the appearance of the molded part.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a combined injection molding device, including a processing table, an installation plate fixedly installed on the upper surface of the processing table, an injection head installed on the lower front surface of the installation plate, and installation frames fixedly installed on both the left and right ends of the upper surface of the processing table.

[0006] The auxiliary mechanism is located on the right-side mounting frame. The auxiliary mechanism includes a mounting box and a fan. A sliding plate is slidably mounted on the inner wall of the right-side mounting frame. An electric push rod is fixedly mounted on the right surface of the sliding plate. The telescopic end of the electric push rod slides through to the left surface of the sliding plate. A clamping plate is fixedly mounted on the telescopic end of the electric push rod. The mounting box is fixedly mounted on the upper surface of the clamping plate. The left side of the mounting box is open. A mounting hole is opened on the right surface of the mounting box. The fan is fixedly mounted inside the mounting hole. The fan is located inside the mounting box.

[0007] Preferably, the auxiliary mechanism further includes multiple guide plates, all of which are fixedly installed on the left side of the inner wall of the mounting box.

[0008] Preferably, there are two auxiliary mechanisms, which are installed in two mounting frames, one on the left and one on the right.

[0009] Preferably, the upper surfaces of both clamping plates are provided with rectangular holes, and reinforcing plates are fixedly connected inside the two rectangular holes.

[0010] Preferably, both of the mounting boxes have connection holes on their lower inner walls.

Motors are fixedly mounted on the rear surfaces of the two mounting frames, and the output ends of the two motors rotatably penetrate into the interior of the mounting frames. The two motors are fixedly connected to the two threaded rods respectively.

[0012] Preferably, a hydraulic assembly is fixedly mounted on the upper surface of the mounting plate, the telescopic end of the hydraulic assembly extends through to the lower surface of the mounting plate, and the hydraulic assembly is fixedly connected to the injection head.

[0013] Compared with the prior art, the present invention provides a combined switch injection molding device, which has the following beneficial effects: the combined switch injection molding device uses a fan to quickly reduce the residual heat of the molded part through directional airflow, so that the surface can be quickly hardened from a slightly soft state, reducing indentations and scratches caused by uneven force when the clamping plate is held, effectively avoiding surface damage when the clamp comes into contact with the high temperature molded part, ensuring the appearance quality of the combined switch components, and improving the injection molding production effect of the combined switch.

[0023] Furthermore, there are two auxiliary mechanisms, which are installed in two mounting frames 4, one on the left and one on the right.

[0024] Furthermore, the fan 6 rapidly reduces the residual heat of the molded part through directional airflow, allowing the surface to harden quickly from a slightly softened state. This reduces indentations and scratches caused by uneven force during clamping, effectively avoiding surface damage when the clamp comes into contact with the high-temperature molded part. This ensures the appearance quality of the combination switch components and improves the injection molding production effect of the combination switch.

[0025] Furthermore, rectangular holes 12 are provided on the upper surfaces of both clamping plates 9, and reinforcing plates 13 are fixedly connected inside the two rectangular holes 12.

[0029] Furthermore, when using this device to injection mold components of the combination switch, after the molded part is ejected, the motor 16 starts, driving the threaded rod 15 in the right mounting frame 4 to rotate, causing the sliding plate 7 to slide forward, bringing the clamping plate 9 closer to the molded part; the left auxiliary mechanism moves synchronously, the two clamping plates form a symmetrical clamping posture, the electric push rod 8 extends, pushing the two clamping plates 9 to move towards the middle, at this time, the fan 6 in the mounting box 5 starts synchronously, blowing air to cool the contact surface between the clamping plate and the molded part and the molded part itself, then the clamping plate 9 clamps the molded part, after which the clamping is stable, the motor 16 reverses, driving the sliding plate 7 to slide forward, taking the molded part out of the mold and transferring it to the next station; the electric push rod retracts, the clamping plate releases the molded part, completing the part removal cycle.
