[0002] An electronic connector is also often referred to as a circuit connector or an electrical connector, which bridges two conductors on a loop, enabling current or signals to flow from one conductor to another. That is, a conductor device that connects two active devices, transmitting current or signals. The male end and the female end can transmit messages or current after contact. Simply put, a component used to complete the electrical connection between circuits or electronic machines, etc. is called a connector, which is the bridge between the two. During the production process of connectors, the connector housing needs to be injection molded. Currently, an injection molding machine is generally used to inject the connector housing.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention:

The raw material particles enter the inside of the cleaning bin through the feeding port at the top of the device body. At the same time, water flows into the water inlet pipe, and then the raw material particles are preliminarily dust-removed through the atomizing nozzle. Moreover, the rotation of the stirring rod drives the raw material particles to be cleaned inside the cleaning bin, so that the water flow washes away the dust attached to the raw material particles through the filtering holes at the bottom of the cleaning bin and flows into the drainage groove. At the same time, the cleaned raw materials are moved to the closing blade by the conveying blade. And the torsion spring drives the hinge to rotate, so that the closing blade rotates and opens, enabling the raw materials to move from the inside of the cleaning bin to the discharge chute and roll through the discharge chute to the discharge port and then flow out, thus completing the cleaning and dust-removing operation of the raw material particles;

[0014] 2. By starting the servo motor to drive the transmission rod to rotate, the first bevel gear is driven to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate, which drives the transmission gear to rotate through the tooth block, and drives the transmission column to rotate and contact the limit plate, so that the limit plate squeezes the return spring to contract and move. The movement of the limit plate drives the cleaning bin to move. The movement of the cleaning bin drives the closing blade to contact the inner wall of the device body, so that the closing blade squeezes the torsion spring to contract and then rotates and closes through the hinge, completing the closing operation of the cleaning bin. When the transmission gear rotates to drive the transmission column to rotate and separate from the limit plate, the limit plate releases the extrusion of the return spring, so that the return spring resets and pushes the limit plate to move back, thereby driving the cleaning bin to move. The movement of the cleaning bin drives the closing blade to move away from the inner wall of the device body, so that the torsion spring resets and drives the closing blade to open. At the same time, the raw materials cleaned inside the cleaning bin are conveyed by the conveying blade and then fall onto the discharge port. The cleaning bin shakes repeatedly in this way, thereby improving the cleaning effect of the raw materials inside the cleaning bin. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The working principle of this utility model:

[0032] Refer to the attached drawings of the specification Figures 2-5 , start the servo motor 201. The start of the servo motor 201 drives the transmission rod 202 to rotate. The rotation of the transmission rod 202 drives the stirring rod 204 and the conveying blade 205 to rotate. The raw material particles enter the inside of the cleaning bin 203 through the feed inlet 101 at the top of the device main body 1. At the same time, water flows into the water inlet pipe 4, and then the raw material particles are preliminarily dust-removed through the atomizing nozzle. Moreover, the rotation of the stirring rod 204 drives the raw material particles to perform a cleaning operation inside the cleaning bin 203, so that the water flow washes away the dust attached to the raw material particles through the filter holes at the bottom of the cleaning bin 203 and flows into the drainage groove. At the same time, the cleaned raw materials are moved to the closing blade 206 by the conveying blade 205, and the torsion spring 209 drives the hinge 208 to rotate, so that the closing blade 206 rotates and opens, enabling the raw materials to move from the inside of the cleaning bin 203 to the discharge chute, and rolling through the discharge chute to the discharge port 301 and then flowing out, thus completing the cleaning and dust-removing operation of the raw material particles;

[0033] Refer to the attached drawings of the specification Figures 2-5 , the start of the servo motor 201 drives the transmission rod 202 to rotate. The rotation of the transmission rod 202 drives the first bevel gear 207 to rotate. The rotation of the first bevel gear 207 drives the second bevel gear 302 to rotate. The rotation of the second bevel gear 302 drives the transmission gear 303 to rotate through the tooth block. The rotation of the transmission gear 303 drives the transmission column 304 to rotate. The rotation of the transmission column 304 contacts the limit plate 305, causing the limit plate 305 to squeeze the return spring 306 to contract and move. The movement of the limit plate 305 drives the cleaning bin 203 to move. The movement of the cleaning bin 203 drives the closing blade 206 to contact the inner wall of the device main body 1, causing the closing blade 206 to squeeze the torsion spring 209 to contract and then rotate and close through the hinge 208, completing the closing operation of the cleaning bin 203. When the rotation of the transmission gear 303 drives the transmission column 304 to rotate and separate from the limit plate 305, the limit plate 305 releases the extrusion of the return spring 306, causing the return spring 306 to reset and push the limit plate 305 to move back, thereby driving the cleaning bin 203 to move. The movement of the cleaning bin 203 moves the closing blade 206 away from the inner wall of the device main body 1, causing the torsion spring 209 to reset and drive the closing blade 206 to open. At the same time, the raw materials cleaned inside the cleaning bin 203 are conveyed by the conveying blade 205 and then fall onto the discharge port 301. The cleaning bin 203 shakes repeatedly in this way, thereby improving the cleaning effect of the raw materials inside the cleaning bin 203.
