Description

Technical Field

[0001] This utility model relates to the technical field of pin insertion molding mechanism, specifically a pin insertion molding mechanism. Background Technology

[0002] The pin-embedded metal molding mechanism, also known as the insert molding mechanism, involves placing the metal part into the mold during the injection molding process, then closing the mold and injecting plastic to coat the metal part, thus forming a plastic part with the metal part embedded. This molding method is commonly used in the production of plugs, terminals, and other products such as power plugs, computer connectors, and gears.

[0003] Chinese utility model patent CN220864592U discloses a precision-positioning injection mold, relating to the field of injection molds. It includes a lower mold and an upper mold for injection molding plugs. The lower mold has multiple lower mold cavities at its top, and multiple slots at the bottom of each lower mold cavity. A heat dissipation cavity is formed inside the lower mold. A sealing plate is bolted to the front of the lower mold, and an air duct communicating with the heat dissipation cavity is fixed to the front of the sealing plate. An air pump is fixed to the air duct. A support plate is provided inside the heat dissipation cavity, and two electric push rods are fixed to the bottom of the support plate. This utility model uses an air pump and air duct to extract air from the heat dissipation cavity, creating suction at the slots. During the insertion of the metal prongs on the terminals into the slots, the suction guides the metal prongs towards the slots, enabling more precise and faster insertion and fixing of the metal prongs, thus improving processing efficiency.

[0004] To cool the raw materials, the aforementioned precisely positioned injection mold is equipped with an air pump, air duct, air inlet, and rubber plug. However, the aforementioned precisely positioned injection mold does not have the function of filtering the gas. Unfiltered gas may contain dust and impurities, which may not only cause blockage of the air duct, air inlet, and other pipes, resulting in poor gas flow and affecting the cooling effect, but the particulate matter contained in the unfiltered gas may also wear down the blades, bearings, and other components of the air pump, leading to a decrease in air pump performance or even damage.

[0011] Furthermore, the front part of the top of the lower mold and the front part of the bottom of the upper mold are both provided with wire grooves, and the cross-section of the wire grooves is semi-circular.

[0012] Compared with the prior art, this utility model provides a pin insertion and forming mechanism, which has the following advantages:

[0013] 1. The pin-embedded molding mechanism, through the setting of connecting pipe, filter box, air inlet pipe and filter screen, allows the air pump to draw external gas into the connecting pipe through the air inlet pipe. The filter screen inside the filter box filters the gas, thereby removing dust and impurities, improving the purity of the gas entering the heat dissipation chamber, ensuring smooth gas flow, improving the working efficiency of the air pump, enhancing the cooling effect, and significantly reducing the wear of internal components such as blades and bearings of the air pump, thus helping to extend the service life of the air pump.

[0014] 2. This pin-embedded forming mechanism, through the setting of a fixed plate, a return spring, a slider, a vibration motor, a dust collection tank, and a transmission block, starts the vibration motor. The output shaft of the vibration motor drives the transmission block to vibrate, and the transmission block transmits the vibration to the filter screen. The slider then slides in the groove.

[0021] Please see Figure 1-4This utility model discloses a pin embedding and forming mechanism, including a lower mold 1. A heat dissipation cavity 201 is formed inside the lower mold 1. A sealing plate 202 is movably arranged on the front of the lower mold 1. An air guide pipe 203 is fixedly arranged in the middle of the sealing plate 202. An air pump 204 is fixedly arranged at one end of the air guide pipe 203. A connecting pipe 205 is fixedly arranged on the back of the lower mold 1. A filter box 206 is fixedly arranged at one end of the connecting pipe 205. An air inlet pipe 207 is fixedly arranged on the back of the filter box 206. A fixed... The top of the fixed plate 301 and the top of the inner wall of the filter box 206 are both provided with sliding grooves, and a slider 303 is movably arranged in the sliding groove. A return spring 302 is fixedly arranged on one side of the slider 303. A filter screen 304 is fixedly arranged between the sliders 303. A dust collection groove 305 is movably arranged on the side of the fixed plate 301 near the air inlet pipe 207. A vibration motor 306 is fixedly arranged on the top of the filter box 206. A transmission block 307 is fixedly arranged on the output shaft of the vibration motor 306. One side of the transmission block 307 is in contact with one side of the filter screen 304.

[0022] Specifically, a valve 208 is provided inside the air intake pipe 207.

[0023] In this embodiment, by setting up an air inlet pipe 207 and a valve 208, closing the valve 208 can cause the slot 402 to generate suction under the action of the air pump 204, thereby fixing the metal insert. During the injection molding process, opening the valve 208 can promote air circulation in the heat dissipation cavity 201 to achieve the purpose of heat dissipation.

[0024] Specifically, the lower mold 1 has a lower mold cavity 401 at the top and a slot 402 at the bottom.

[0025] In this embodiment, by setting a lower mold cavity 401 and a slot 402, the length of the slot 402 is less than the length of the metal prong on the plug. After the metal prong is inserted into the slot 402, one end of it will extend into the interior of the heat dissipation cavity 201 to facilitate demolding of the plug.

[0026] Specifically, the lower mold 1 is provided with an upper mold 403 at its top, and the lower mold 403 is provided with an upper mold cavity 404 at its bottom, which corresponds to the lower mold cavity 401.

[0027] In this embodiment, by setting up a lower mold 1, a lower mold cavity 401, an upper mold 403, and an upper mold cavity 404, when the upper mold 403 covers the top of the lower mold 1, the lower mold cavity 401 and the upper mold cavity 404 can be combined to form a complete cavity, so as to facilitate the injection molding of the plug.

[0028] Specifically, an injection port 405 is fixedly provided on the top of the upper mold cavity 404.

[0029] In this implementation plan, by setting the injection port 405, workers can quickly inject molten raw materials into the lower mold cavity 401 and the upper mold cavity 404 through the injection port 405, thereby improving work efficiency.

[0030] Specifically, the front part of the top of the lower mold 1 and the front part of the bottom of the upper mold 403 are provided with wire grooves 406, and the cross-section of the wire grooves 406 is semi-circular.

[0031] In this embodiment, by providing a wire groove 406, the wire groove 406 can accommodate the wires connected to the terminals, thus preventing damage to the wires.

[0032] In use, place the plug terminals inside the lower mold cavity 401, close valve 208, and start air pump 204. Under the action of air pump 204, air inside the heat dissipation cavity 201 is drawn out through air guide pipe 203, while external air is drawn into the heat dissipation cavity 201 through slot 402, thereby generating suction at slot 402. This guides the metal insert to move towards slot 402, thus accurately and quickly inserting the metal insert into slot 402 for fixation. Place upper mold 403 on top of lower mold 1 and connect the terminals. The wire is located in the wire groove 406. Then, the lower mold 1 and the upper mold 403 are connected together by bolts. The molten raw material is injected into the lower mold cavity 401 and the upper mold cavity 404 through the injection port 405. When the valve 208 is opened, the air pump 204 draws the outside air into the connecting pipe 205 through the air inlet pipe 207. The filter screen 304 inside the filter box 206 will filter the air to remove dust and impurities. The air flow is used to achieve heat dissipation and improve cooling efficiency. After the raw material solidifies and is formed, the plug can be made.

[0033] When the filter screen 304 needs to be cleaned, the vibration motor 303 is started. The output shaft of the vibration motor 303 drives the transmission block 307 to vibrate. The transmission block 307 transmits the vibration to the filter screen 304, and the slider 306 slides in the groove. Under the elastic force of the return spring 302, the slider 306 drives the filter screen 304 to move back and forth, thereby shaking off the dust and impurities attached to its surface into the dust collection tank 305, thus realizing the automatic cleaning of the filter screen 304 and the collection of dust and impurities.

[0034] In summary, this pin-embedding mechanism, through the configuration of a connecting pipe 205, a filter box 206, an air inlet pipe 207, and a filter screen 304, allows the air pump 204 to draw external gas into the connecting pipe 205 via the air inlet pipe 207. The filter screen 304 inside the filter box 206 then filters the gas, removing dust and impurities, thus improving the purity of the gas entering the heat dissipation chamber 201. This ensures smooth gas flow, improves the working efficiency of the air pump 204, enhances the cooling effect, and significantly reduces wear on internal components such as blades and bearings of the air pump 204, helping to extend its service life. Furthermore, the mechanism incorporates a fixing plate 301 and a return spring 304. 02. Slider 306, vibration motor 303, dust collection tank 305, and transmission block 307. When the vibration motor 303 is started, its output shaft drives the transmission block 307 to vibrate. The transmission block 307 transmits the vibration to the filter screen 304, and the slider 306 slides in the groove accordingly. Under the elastic force of the return spring 302, the slider 306 drives the filter screen 304 to move back and forth, thereby shaking off the dust and impurities attached to its surface into the dust collection tank 305. This achieves automatic cleaning of the filter screen 304, reduces the risk of airflow obstruction due to filter screen 304 blockage, effectively improves the filtration efficiency of the filter screen 304, and further enhances the heat dissipation effect.
