Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and in particular relates to an injection mold for producing coil bobbins. Background Technology

[0002] Existing injection molds for producing coil bobbins consist of a fixed mold and a moving mold. After the molds are closed, a cavity is formed for molding the coil bobbin. The cavity is connected to the sprue of the injection molding machine to inject molten material. After molding, the fixed mold and the moving mold separate to demold the coil bobbin. However, a small amount of incompletely molded molten material is easily left at the edge of the cavity and the connection with the sprue. In addition, some areas of the inner wall of the cavity have depressions or corner structures. These residual molten materials are difficult to detach with the coil bobbin. Long-term accumulation will affect the molding accuracy of subsequent products. The cavity structure of the mold is closed and the inner wall is smooth. There is a lack of auxiliary structures for cleaning residual molten material. As a result, operators need to use thin and long tools to go deep into the cavity to scrape off the residue. The operation is cumbersome and can easily scratch the inner wall of the cavity, affecting the performance of the mold.

[0003] Chinese patent application CN218576819U discloses a continuous production coil bobbin injection molding mechanism, including a base, characterized by further including a demolding component and a temperature control component. The demolding component specifically consists of a lower mold plate, a sliding block, a slide rail, a servo motor, an injection baffle, a connector, and a lead screw. The top of the base is constructed with a slide rail, and two sets of slide rails are provided. A sliding block is slidably connected in both sets of slide rails. A lead screw is movably connected in a groove in the gap between the two sets of slide rails on the base. A servo motor is installed on the side of the base near the lead screw, and the power output end of the servo motor is connected to the power input end of the lead screw through a coupling. The sliding block is threadedly connected to the lead screw through a bottom gap. A connector is welded to the surface of the sliding block away from the servo motor. The lower mold plate, which is slidably connected to the bottom of the connector and the surface of the base, is fixedly connected to the side of the connector away from the sliding block. Injection baffles are fixedly connected to both sides of the inner wall of the lower mold plate.

[0004] Although demolding is achieved by using a servo motor to drive a lead screw to move a sliding block and a lower mold plate, eliminating the need for manual demolding, it is not only simple and convenient to operate, but also reduces labor costs and improves demolding efficiency. It also has a temperature control component, which, through the cooperation of a high-temperature heating resistor, a temperature sensor, and a PLC controller, can control the temperature of the injection molding mechanism, which helps to ensure the molding effect of the injection molding material and thus improve the production quality of the coil frame. Moreover, the overall structure is suitable for continuous production scenarios and can meet the needs of mass production. However, it does not have a cleaning component similar to that of a comparison mold. After injection molding, there may be residual injection molding material residues and other impurities in the mold, which may affect the precision of subsequent injection molded products in the long run.

[0005] To address these issues, we provide an injection mold for producing coil bobbins. Utility Model Content

Finally, the moving mold 31, the fixed mold 4 and the two clamping molds 54 close together to form a complete mold cavity. Subsequently, the delivery pump injects the material into the cavity through the delivery hose for injection molding. After the product is demolded, the cleaning program is started: First, the first motor 33 in the cleaning component 3 drives the deflector wheel 34 to rotate at high speed. The vibration generated is transmitted to the moving mold 31 through the hollow mold rod 32, effectively loosening the residual material attached to the surface of the cavity. At the same time, the water pump 37 continuously pumps water from the water tank 36 through the water hose 38 to rinse the cavity. The water flow can more effectively remove the residue with the assistance of vibration. Subsequently, the high-pressure air jet mechanism 55 is activated as an auxiliary cleaning method. The high-pressure airflow generated by the air pump 552 is ejected through the micro air outlets inside the clamping mold 54, precisely blowing away the corners of the cavity and the joints of the clamping mold 54 to ensure that residual water droplets and fine material debris are thoroughly removed. The entire process, through a combination of vibration, water rinsing, and high-pressure air blowing, achieves efficient and thorough cleaning of complex mold cavities.
