The injection cylinder provides injection pressure to inject molten plastic into the mold cavity, and the nozzle connects the barrel and the mold.

[0003] Cooling is required during the injection molding process of the electric energy meter housing. The cooling water of most devices needs to dissipate heat. During the process of cooling water contacting the air for heat dissipation, dust particles in the air will enter the cooling water. Since the cooling water needs to be recycled, dust particles will precipitate when entering the cooling system. As the dust particles accumulate more and more, blockage will occur, thus affecting the normal operation of the cooling system. Summary of the invention

[0004] The purpose of the present invention is to provide an injection molding device for producing an electric energy meter shell and a method for using the same, so as to solve the problem that dust particles in the air will enter the cooling water. Since the cooling water needs to be circulated, the dust particles will precipitate when entering the cooling system.

[0006] Further, a T-shaped cavity is formed in the injection molding box. The T-shaped cavity communicates with the cooling tank. A rotating shaft is rotatably installed in the T-shaped cavity. The end of the rotating shaft extends outside the injection molding box. A plurality of driving fan blades are fixedly installed on the rotating shaft.

[0007] Further, a vacuum mechanism is arranged on the rotating shaft. The vacuum mechanism includes a circular vibration box rotatably sleeved on the rotating shaft. The circular vibration box is fixedly connected to the injection molding box. A plurality of vacuum fan blades are fixedly installed on the rotating shaft. A vacuum tube is fixedly installed on the back of the circular vibration box. The bottom of the vacuum tube is fixedly connected to the injection molding box. A connecting hose is fixedly installed on the top of the vacuum tube.

[0008] Further, a rectangular extrusion plate is arranged on the bottom inner wall of the rectangular groove. A vacuum hood is fixedly installed on the top of the rectangular extrusion plate. The vacuum hood is fixedly connected to the connecting hose. A plurality of exhaust holes are formed in the rectangular extrusion plate, and all the plurality of exhaust holes penetrate through the rectangular extrusion plate.

[0009] Further, a heat dissipation mechanism is arranged on the back of the injection molding box. The heat dissipation mechanism includes a rectangular heat dissipation box fixedly installed on the back of the injection molding box. A water inlet tank is formed in the rectangular heat dissipation box. A drain pipe is fixedly installed on the left side of the rectangular heat dissipation box. The front end of the drain pipe communicates with the T-shaped cavity. An inclined groove is formed in the rectangular heat dissipation box, and the inclined groove communicates with the water inlet tank. A water outlet groove is formed in the back of the rectangular heat dissipation box.

[0010] Further, a U-shaped baffle is fixedly installed on the back of the rectangular heat dissipation box. The front surface of the U-shaped baffle is fixedly connected to the injection molding box. A plurality of ventilation strip-shaped grooves are respectively formed on the left side and the right side of the U-shaped baffle. A exhaust strip-shaped groove is fixedly installed on the back of the circular vibration box.

[0011] Further, a transmission wheel is fixedly sleeved on the rotating shaft. A rotating shaft is fixedly sleeved on the rotating rod. A transmission belt is sleeved on the two rotating shafts.

[0012] Further, a method for an injection molding device for producing an electric energy meter housing is as follows: S1: After injecting plastic into the box-shaped mold cavity, start the submersible pump. The submersible pump will pump out the cooling water in the water storage tank and discharge it into the cooling tank through the water outlet pipe. The cooling water will fill the entire cooling tank and continuously cool down the plastic in the box-shaped mold cavity through the inner wall of the box-shaped mold cavity. Then the cooling water will flow from the cooling tank into the T-shaped cavity, and the water flow will enter the water inlet tank from the T-shaped cavity through the drain pipe. Due to the large water pressure, after the cooling water enters the water inlet tank, it will be buffered by the water inlet tank. Then the liquid level of the cooling water will continuously rise in the water inlet tank, and the cooling water will overflow through the inclined groove and the water outlet groove. At this time, the cooling water will be relatively gentle; S2: After the cooling water flows out of the water outlet tank, it will enter the U-shaped baffle. The cooling water will freely fall in the U-shaped baffle along the outer wall of the water outlet tank. During this process, the cooling water will increase the contact area with the air, thereby improving the cooling effect of the cooling water. The ventilation strip-shaped grooves on both sides of the U-shaped baffle will also improve the air circulation to help the cooling water cool down quickly, so as to ensure the uniformity of cooling when the cooling water after passing through the U-shaped baffle cools the plastic again; S3: When the cooling water enters the T-shaped cavity, it will drive several drive fan blades to rotate. The drive fan blades will drive the rotating shaft to rotate, and the rotating shaft will drive the drive wheel to rotate. Since there is also a drive wheel sleeved on the rotating rod, the rotating shaft will drive the rotating rod to rotate simultaneously under the action of the drive wheel and the drive belt. The rotating rod will drive the disc to rotate, and the disc will drive the trapezoidal vibration block in the vibration groove to rotate. Since the rotating shaft rotates relatively fast, the trapezoidal vibration block will generate vibration when it contacts the filter box. The vibration will cause the dust and impurities attached to the filter holes on the front of the filter box to fall off, and the fallen dust particles will fall on the bottom inner wall of the filter box; S4: During the rotation of the rotating shaft, it will drive several vacuum fan blades to rotate. The rotation of the vacuum fan blades will generate a vacuum suction force. The vacuum suction force will suck air into the vacuum hood through the vacuum tube and the connecting hose. The suction force will suck air into the plastic again through several vacuum hoods on the rectangular pressing plate to form a vacuum state. The vacuum hood in the vacuum state will discharge the air in the plastic into the vacuum hood, and the air in the plastic will be discharged from the exhaust strip-shaped groove, thereby preventing the plastic from containing gas during injection molding.

[0013] The present invention has the following beneficial effects: (1) For the injection molding device for producing the electricity meter housing of the present invention, when the cooling water enters the T-shaped cavity, it will drive several drive fan blades to rotate. The drive fan blades will drive the rotating shaft to rotate, and the rotating shaft will drive the drive wheel to rotate. Since there is also a drive wheel sleeved on the rotating rod, the rotating shaft will drive the rotating rod to rotate simultaneously under the action of the drive wheel and the drive belt. The rotating rod will drive the disc to rotate, and the disc will drive the trapezoidal vibration block in the vibration groove to rotate. Since the rotating shaft rotates relatively fast, the trapezoidal vibration block will generate vibration when it contacts the filter box. The vibration will cause the dust and impurities attached to the filter holes on the front of the filter box to fall off, and the fallen dust particles will fall on the bottom inner wall of the filter box, so as to effectively keep the cooling water after heat dissipation flowing smoothly into the water storage tank and ensure the normal operation of the injection molding cooling work; (2) For the injection molding device used in the production of the electric energy meter housing of the present invention, after injecting plastic into the box-shaped die cavity, start the submersible pump. The submersible pump will extract the cooling water in the water storage tank and discharge it into the cooling tank through the water outlet pipe. The cooling water will fill the entire cooling tank and continuously cool down the plastic in the box-shaped die cavity through the inner wall of the box-shaped die cavity. Then, the cooling water will flow from the cooling tank into the T-shaped cavity, and the water flow will enter the water inlet tank through the drain pipe from the T-shaped cavity. Due to the relatively large water pressure, after the cooling water enters the water inlet tank, it will be buffered by the water inlet tank. Then, the liquid level of the cooling water will continuously rise in the water inlet tank, and the cooling water will overflow through the inclined groove and the water outlet tank. At this time, the cooling water will be relatively gentle, avoiding the direct spraying out of the cooling water after it enters the water inlet tank, thereby reducing the waste of cooling water and reducing the working pressure of replenishing cooling water. (3) For the injection molding device used in the production of the electric energy meter housing of the present invention, after the cooling water flows out of the water outlet tank, it will enter the C-shaped baffle. The cooling water will freely fall in the C-shaped baffle along the outer wall of the water outlet tank. During this process, the cooling water will increase the contact area with the air, thereby improving the cooling effect of the cooling water. The ventilation strip-shaped grooves on both sides of the C-shaped baffle will also improve the air circulation to help the rapid cooling of the cooling water, thereby ensuring the uniformity of cooling when the cooling water after passing through the C-shaped baffle cools the plastic again, and avoiding the uneven cooling of the plastic, resulting in the continued shrinkage of the relatively slowly cooled part while the surrounding parts that have cooled and solidified will limit its shrinkage, thereby forming shrink marks on the surface. (4) For the injection molding device used in the production of the electric energy meter housing of the present invention, during the rotation of the rotating shaft, a number of vacuum fan blades will be driven to rotate. The rotation of the vacuum fan blades will generate a vacuum suction force. The vacuum suction force will suck air into the vacuum hood through the vacuum tube and the connecting hose. The suction force will again suck air from a number of vacuum hoods on the rectangular extrusion plate to the plastic to form a vacuum state. The vacuum hood in the vacuum state will discharge the air in the plastic into the vacuum hood, and the air in the plastic will be discharged from the exhaust strip-shaped groove, thereby avoiding the gas in the plastic during injection molding, resulting in defective bubbles in the injection-molded finished product, and further improving the quality of the electric energy meter housing.

[0014] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

A cooling groove 4 is provided in the injection molding box 1. It is characterized in that it further includes: The vibration mechanism 5 includes a water storage tank 501 provided in the injection molding box 1, a submersible pump 502 is fixedly installed on the inner wall of the bottom of the water storage tank 501, a water suction pipe 503 is fixedly installed on the right end of the submersible pump 502, a water outlet pipe 504 is fixedly installed on the right side of the submersible pump 502, and the top of the water outlet pipe 504 is communicated with the cooling tank 4, a rotating rod 505 is rotatably installed on the injection molding box 1, and the front end of the rotating rod 505 extends into the water storage tank 501, and the rotating rod 505 is fixedly installed on the right side of the submersible pump 502. The fixed sleeve is provided with a disc 506, on which a plurality of vibration grooves 507 are opened, and vibration springs 508 are fixedly installed on the inner walls of the sides of the plurality of vibration grooves 507 that are close to each other, and trapezoidal vibration blocks 509 are fixedly installed on the ends of the plurality of vibration springs 508 that are away from each other, and the plurality of trapezoidal vibration blocks 509 are slidably extended to the outside of the disc 506, and a filter box 510 is slidably installed in the water storage tank 501, and the right side of the filter box 510 extends to the outside of the injection molding box 1.

[0020] like Figure 2 As shown, a T-shaped cavity 511 is provided in the injection molding box 1 , the T-shaped cavity 511 is communicated with the cooling groove 4 , a rotating shaft 512 is rotatably installed in the T-shaped cavity 511 , the end of the rotating shaft 512 extends to the outside of the injection molding box 1 , and a plurality of transmission blades 513 are fixedly installed on the rotating shaft 512 .

[0021] When the cooling water flows into the T-shaped cavity 511 , it drives a plurality of transmission blades 513 to rotate, and the transmission blades 513 drive the rotating shaft 512 to rotate.

[0022] As Figure 3 and Figure 5 As shown, a vacuum mechanism 6 is provided on the rotating shaft 512, and the vacuum mechanism 6 includes a circular vibration box 601 rotatably mounted on the rotating shaft 512, the circular vibration box 601 is fixedly connected to the injection molding box 1, a plurality of vacuum fan blades 602 are fixedly installed on the rotating shaft 512, a vacuum tube 603 is fixedly installed on the back of the circular vibration box 601, the bottom of the vacuum tube 603 is fixedly connected to the injection molding box 1, and a connecting hose 604 is fixedly installed on the top of the vacuum tube 603.

[0023] During the rotation of the rotating shaft 512 , a plurality of vacuum blades 602 will be driven to rotate. The rotation of the vacuum blades 602 will generate vacuum suction, and the vacuum suction will draw air into the vacuum cover 606 through the vacuum tube 603 and the connecting hose 604 .

[0024] like Figure 2 and Figure 3 As shown, a rectangular extrusion plate 605 is provided on the bottom inner wall of the rectangular groove 3, a vacuum cover 606 is fixedly installed on the top of the rectangular extrusion plate 605, the vacuum cover 606 is fixedly connected to the connecting hose 604, and a plurality of exhaust holes 607 are opened on the rectangular extrusion plate 605, and the plurality of exhaust holes 607 all penetrate the rectangular extrusion plate 605.

[0025] The suction force will again form a vacuum state by sucking air from the plastic through a number of vacuum covers 606 on the rectangular extrusion plate 605. The air in the plastic will be discharged into the vacuum cover 606 under the vacuum state.

[0026] As Figure 5 and Figure 7 shown, a heat dissipation mechanism 7 is provided on the back of the injection molding box 1. The heat dissipation mechanism 7 includes a rectangular heat dissipation box 701 fixedly installed on the back of the injection molding box 1. A water inlet tank 702 is provided in the rectangular heat dissipation box 701. A drain pipe 703 is fixedly installed on the left side of the rectangular heat dissipation box 701. The front end of the drain pipe 703 communicates with the T-shaped cavity 511. An inclined slot 704 is provided on the rectangular heat dissipation box 701, and the inclined slot 704 communicates with the water inlet tank 702. A water outlet tank 705 is provided on the back of the rectangular heat dissipation box 701.

[0027] After the cooling water enters the water inlet tank 702, it will be buffered through the water inlet tank 702. Then the liquid level of the cooling water will continue to rise in the water inlet tank 702. The cooling water will overflow through the inclined slot 704 and the water outlet tank 705. At this time, the cooling water will be relatively gentle, avoiding the direct spraying out of the cooling water after it enters the water inlet tank 702, thereby reducing the waste of cooling water and reducing the working pressure of replenishing cooling water.

[0028] As Figure 5 and Figure 7 shown, a U-shaped baffle 706 is fixedly installed on the back of the rectangular heat dissipation box 701. The front of the U-shaped baffle 706 is fixedly connected to the injection molding box 1. A number of ventilation strip-shaped slots 707 are respectively provided on the left side and the right side of the U-shaped baffle 706. A discharge air strip-shaped slot 708 is fixedly installed on the back of the circular vibration box 601.

[0029] After the cooling water flows out from the water outlet tank 705, it will enter the U-shaped baffle 706. The cooling water will freely fall in the U-shaped baffle 706 along the outer wall of the water outlet tank 705. During this process, the cooling water will increase the contact area with the air, thereby improving the cooling effect of the cooling water. The ventilation strip-shaped slots 707 on both sides of the U-shaped baffle 706 will also improve the air circulation to help the rapid cooling of the cooling water, thereby ensuring the uniformity of cooling when the cooling water after passing through the U-shaped baffle 706 cools the plastic again, and avoiding the uneven cooling of the plastic, resulting in the continued shrinkage of the relatively slowly cooled part while the surrounding already cooled and solidified part restricts its shrinkage, thus forming shrink marks on the surface.

[0030] As Figure 4 and Figure 5 shown, a transmission wheel 709 is fixedly sleeved on the rotating shaft 512. A rotating shaft 512 is fixedly sleeved on the rotating rod 505. A transmission belt 710 is sleeved on the two rotating shafts 512.

[0031] The driving fan blade 513 will drive the rotating shaft 512 to rotate, and the rotating shaft 512 will drive the driving wheel 709 to rotate. Since the driving wheel 709 is also sleeved on the rotating rod 505, the rotating shaft 512 will drive the rotating rod 505 to rotate under the action of the driving wheel 709 and the driving belt 710.

[0032] Such as Figure 1-8 shown is a method for an injection molding device used in the production of an electric energy meter housing, and the method steps are as follows: S1: After injecting plastic into the box-shaped die cavity 2, start the submersible pump 502. The submersible pump 502 will pump out the cooling water in the water storage tank 501 and discharge it into the cooling tank 4 through the water outlet pipe 504. The cooling water will fill the entire cooling tank 4 and continuously cool down the plastic in the box-shaped die cavity 2 through the inner wall of the box-shaped die cavity 2. Then the cooling water will flow from the cooling tank 4 into the T-shaped cavity 511, and the water flow will enter the water inlet tank 702 from the T-shaped cavity 511 through the drain pipe 703. Due to the large water pressure, after the cooling water enters the water inlet tank 702, it will be buffered by the water inlet tank 702. Then the liquid level of the cooling water will continuously rise in the water inlet tank 702, and the cooling water will overflow through the inclined groove 704 and the water outlet tank 705. At this time, the cooling water will be relatively gentle; S2: After the cooling water flows out of the water outlet tank 705, it will enter the C-shaped baffle 706. The cooling water will freely fall in the C-shaped baffle 706 along the outer wall of the water outlet tank 705. During this process, the cooling water will increase the contact area with the air, thereby improving the cooling effect of the cooling water. The ventilation strip-shaped grooves 707 on both sides of the C-shaped baffle 706 will also improve the air circulation to help the rapid cooling of the cooling water, so as to ensure the uniformity of cooling when the cooling water after passing through the C-shaped baffle 706 cools the plastic again; S3: When the cooling water enters the T-shaped cavity 511, it will drive several driving fan blades 513 to rotate. The driving fan blade 513 will drive the rotating shaft 512 to rotate, and the rotating shaft 512 will drive the driving wheel 709 to rotate. Since the driving wheel 709 is also sleeved on the rotating rod 505, the rotating shaft 512 will drive the rotating rod 505 to rotate under the action of the driving wheel 709 and the driving belt 710. The rotating rod 505 will drive the disc 506 to rotate, and the disc 506 will drive the trapezoidal vibration block 509 in the vibration groove 507 to rotate. Since the rotation of the rotating shaft 512 is relatively fast, the trapezoidal vibration block 509 will generate vibration when it contacts the filter box 510. The vibration will cause the dust and impurities attached to the filter holes on the front of the filter box 510 to fall off, and the fallen dust particles will fall onto the bottom inner wall of the filter box 510; S4: During the rotation of the rotating shaft 512, several vacuum blades 602 will be driven to rotate. The rotation of the vacuum blades 602 will generate vacuum suction, which will draw air into the vacuum cover 606 through the vacuum tube 603 and the connecting hose 604. The suction will again draw air into the plastic through several vacuum covers 606 on the rectangular extrusion plate 605 to form a vacuum state. The vacuum cover 606 in the vacuum state will discharge the air in the plastic into the vacuum cover 606, and the air in the plastic will be discharged from the exhaust strip groove 708, thereby preventing the plastic from containing gas during injection molding.

7. The injection molding device for producing an electric energy meter housing according to claim 6, characterized in that: A transmission wheel (709) is fixedly sleeved on the rotating shaft (512). A rotating shaft (512) is fixedly sleeved on the rotating rod (505). A transmission belt (710) is sleeved on the two rotating shafts (512).

8. A method for using an injection molding device for producing an electric energy meter housing, using the injection molding device for producing an electric energy meter housing as claimed in claim 7, characterized in that: The method steps are as follows: S1: After injecting plastic into the box-shaped mold cavity (2), start the submersible pump (502). The submersible pump (502) will pump out the cooling water in the water storage tank (501) and discharge it into the cooling tank (4) through the water outlet pipe (504). The cooling water will fill the entire cooling tank (4) and continuously cool down the plastic in the box-shaped mold cavity (2) through the inner wall of the box-shaped mold cavity (2). Then the cooling water will flow from the cooling tank (4) into the T-shaped cavity (511), and the water flow will enter the water inlet tank (702) from the T-shaped cavity (511) through the drain pipe (703). Due to the relatively large water pressure, after the cooling water enters the water inlet tank (702), it will be buffered through the water inlet tank (702). Then the liquid level of the cooling water will continuously rise in the water inlet tank (702), and the cooling water will overflow through the inclined slot (704) and the outlet water tank (705). At this time, the cooling water will be relatively gentle; S2: After the cooling water flows out from the outlet water tank (705), it will enter the U-shaped baffle (706). The cooling water will freely fall in the U-shaped baffle (706) along the outer wall of the outlet water tank (705). During this process, the cooling water will increase the contact area with the air, thereby improving the cooling effect of the cooling water. The ventilation strip-shaped slots (707) on both sides of the U-shaped baffle (706) will also improve the air circulation to help the rapid cooling of the cooling water, so as to ensure the uniformity of cooling when the cooling water after passing through the U-shaped baffle (706) cools the plastic again; S3: When the cooling water enters the T-shaped cavity (511), it drives a plurality of transmission blades (513) to rotate, and the transmission blades (513) drive the rotating shaft (512) to rotate, and the rotating shaft (512) drives the transmission wheel (709) to rotate. Since the rotating rod (505) is also provided with a transmission wheel (709), the rotating shaft (512) drives the rotating rod (505) to rotate at the same time under the action of the transmission wheel (709) and the transmission belt (710). The rotating rod (505) drives the disc (506) to rotate, and the disc (506) drives the trapezoidal vibration block (509) in the vibration groove (507) to rotate. Since the rotating shaft (512) rotates faster, the trapezoidal vibration block (509) will vibrate when it contacts the filter box (510), and the vibration will cause dust impurities attached to the filter holes on the front of the filter box (510) to fall off, and the dust particles that fall off will fall onto the bottom inner wall of the filter box (510); S4: During the rotation of the rotating shaft (512), a plurality of vacuum blades (602) are driven to rotate. The rotation of the vacuum blades (602) generates vacuum suction. The vacuum suction draws air into the vacuum cover (606) through the vacuum tube (603) and the connecting hose (604). The suction draws air into the plastic through the plurality of vacuum covers (606) on the rectangular extrusion plate (605) to form a vacuum state. The vacuum cover (606) in the vacuum state discharges the air in the plastic into the vacuum cover (606). The air in the plastic is discharged from the exhaust strip groove (708), thereby preventing the plastic from containing gas during injection molding.
