[0040] Specifically, when the device is injection molding the washing machine shell, the second mold 22 is moved so that the second mold groove 221 is connected with the first mold groove 211, and then plastic is injected into the second mold groove 221 through the injection molding mechanism 4. At the same time, coolant is introduced into the first cooling groove 31 and the second cooling groove 32 through the external liquid adding mechanism. The coolant gradually fills the first cooling groove 31 and the second cooling groove 32. At the same time, the coolant flows into the third cooling groove 33 through the second cooling groove 32 and the connecting piece 34. When the cooling is completed, the coolant is extracted from the first cooling groove 31 and the second cooling groove 32 through the external liquid adding mechanism.

[0041] By setting the first cooling groove 31, the second cooling groove 32 and the third cooling groove 33, the inner and outer sides of the first mold groove 211 and the second mold groove 221 can be cooled, thereby improving the cooling effect and accelerating the cooling speed of the washing machine shell formed in the first mold groove 211 and the second mold groove 221, so that the washing machine shell can be quickly taken out of the mold, facilitating the mold to carry out a new production process, thereby improving the working efficiency of the device.

[0042] It should be noted that the external liquid adding mechanism is a prior art and will not be described in detail.

[0045] Specifically, when the second module 22 is required to approach the first module 21 , the electric push rod 143 is started so that the output end of the electric push rod 143 drives the second module 22 to approach the first module 21 .

[0046] It should be noted that the electric push rod 143 is a prior art and will not be described in detail.

[0047] Further, such as Figure 3As shown, the first module 21 also includes a hydraulic rod 213, the output end of the hydraulic rod 213 is fixedly connected to a molding plate 215, the molding plate 215 is slidably connected to the inner wall of the first mold groove 211, and a molding block 214 is fixedly connected to the molding plate 215.

[0048] Specifically, after the washing machine shell is cooled and formed, the hydraulic rod 213 is started, and the output end of the hydraulic rod 213 drives the forming plate 215 and the forming block 214 to move toward the second module 22 to eject the washing machine shell from the first mold groove 211 .

[0049] By setting the molding plate 215, the washing machine shell can be ejected from the first mold groove 211 after molding, and scraping occurs between the molding plate 215 and the inner wall of the first mold groove 211 to prevent plastic from adhering to the first mold groove 211 and affecting the subsequent injection molding effect.

[0051] Specifically, when the first mold body 212 abuts against the second mold body 222, the abutment rod 347 abuts against the closing cover 343, and the abutment rod 347 drives the closing cover 343 away from the connecting pipe 342, and at the same time stretches the third spring 344, so that the second cooling groove 32 is connected with the connecting pipe 342, and the coolant enters the third cooling groove 33 through the second cooling groove 32, the connecting pipe 342 and the one-way valve 346.

[0052] By providing the connecting piece 34, the coolant can enter the third cooling groove 33 to cool the bottom of the washing machine housing, while improving the utilization efficiency of the coolant.

[0053] like Figure 5 , 6 As shown, a push plate 36 is slidably disposed in the third cooling groove 33 , and a second spring 37 is connected between the push plate 36 and a side wall of the third cooling groove 33 away from the first module 21 .

[0054] Specifically, after the coolant enters the third cooling groove 33 , as the amount of coolant gradually increases, the push plate 36 is driven to move away from the first module 21 , and the second spring 37 is compressed at the same time.

[0055] like Figure 6 As shown, the injection mechanism 4 includes an injection port 41, which is located at the center of the second mold groove 221. The injection port 41 is connected to the second mold groove 221, and a cutting mechanism 5 is sleeved on the injection port 41. The cutting mechanism 5 includes an annular mounting groove 51 embedded in the second mold groove 221 and opening toward the first mold 21.

Each sliding groove 53 is provided with a cutting knife 54 sliding along the radial direction of the rotating disk 52. The side of the cutting knife 54 away from the first mold 21 is an inclined surface, and the end of the cutting knife 54 close to the injection port 41 is pointed, and the ends of the two cutting knives 54 can abut.

[0056] like Fig. 9 As shown, sliding members 50 are respectively arranged in two opposite side walls of the sliding groove 53, and the sliding member 50 includes a moving groove 501 opened in the sliding groove 53, a moving block 502 is slidably arranged in the moving groove 501, a fourth spring 503 is connected between the moving block 502 and a side wall of the moving groove 501 close to the axis of the injection port 41, and the cutting knife 54 is fixedly connected between the two moving blocks 502.

[0057] Specifically, when the rotating disk 52 does not extend out of the mounting slot 51, the fourth spring 503 is in a stretched state. When the washing machine shell needs to be pushed out, the electric push rod 143 is first started, and the electric push rod 143 drives the second module 22 to move away from the first module 21. At the same time, the moving block 502 drives the cutting knife 54 to move toward the injection port 41 under the action of the fourth spring 503. When the ends of the two cutting knives 54 abut, the plastic connecting the bottom of the washing machine shell and the injection port 41 is cut off, and then the movement of the electric push rod 143 is stopped. At the same time, the cutting knife 54 abuts against the bottom surface of the washing machine shell, and then the electric push rod 143 is synchronously started to And the hydraulic rod 213, the hydraulic rod 213 drives the forming block 214 to push out the washing machine shell, the electric push rod 143 drives the second module 22 and the forming block 214 to move in the same direction, and at the same time rotates the rotating disk 52, the rotating disk 52 drives the cutting knife 54 to rotate, and the plastic cut-off part of the bottom of the washing machine shell is polished; when the polishing is completed, the rotating disk 52 needs to be reset, and the rotating disk 52 is retracted into the installation groove 51. During this process, the inclined surface of the cutting knife 54 abuts against the end surface of the rotating sleeve 581, so that the cutting knife 54 moves in the direction away from the axis of the injection port 41, and the cutting knife 54 drives the moving block 502 to move, and the fourth spring 503 is stretched again.

[0058] By setting the cutting knife 54, after the washing machine shell is cooled and formed, the cutting knife can cut off the plastic connecting the bottom of the washing machine shell and the injection port 41, and can also grind the cut part, thereby reducing the subsequent manual processing work of the washing machine shell and improving work efficiency.

[0059] like Figure 6 , 10 As shown, the side of the cutting knife 54 close to the first module 21 is a plane, and the two opposite side walls of each sliding groove 53 are fixedly connected with a supplementary plate 55.

The outer circumferential side wall of the mounting groove 51 is fixedly connected with a limiting ring 59, and the limiting ring 59 is located on the side of the rotating disk 52 away from the first module 21.

[0060] By providing the supplementary plate 55 and the limiting ring 59, when the device is performing injection molding, the supplementary plate 55, the cutting knife 54 and the rotating disk 52 can together form a closed surface, thereby preventing the bottom of the washing machine shell from bulging during molding and affecting the production quality of the washing machine shell.

[0061] like Figure 6 As shown, the third cooling groove 33 is connected with the mounting groove 51 through the drainage part 35, and the drainage part 35 includes a connecting groove 351 connected between the third cooling groove 33 and the mounting groove 51, and an electromagnetic on-off valve 352 is fixedly arranged in the connecting groove 351.

A drainage groove 57 is opened in the cutting knife 54, and one end of the drainage groove 57 can be connected with the connecting hole 56, and the other end of the drainage groove 57 is opened on the inclined surface of the cutting knife 54.

[0062] Specifically, when the washing machine shell needs to be ejected, the electromagnetic on-off valve 352 is opened, so that the coolant in the third cooling groove 33 enters the installation groove 51 through the connecting groove 351 under the action of the push plate 36 and the second spring 37. As the coolant in the installation groove 51 gradually increases, the rotating disk 52 is ejected from the installation groove 51 under the action of the pressure of the coolant. When the ends of the two cutting knives 54 abut, the drainage groove 57 is connected with the connecting hole 56, and the coolant in the installation groove 51 is sprayed onto the injection port 41 through the connecting hole 56 and the drainage groove 57.

[0063] By providing the drain groove 57 and the drain member 35, the used coolant can be discharged through the drain groove 57, and since the opening of the drain groove 57 is provided on the inclined surface of the cutting knife 54, the sprayed liquid is sprayed on the injection port 41, preventing the residual plastic on the injection port 41 from clogging the injection port 41 and affecting the subsequent work.

The output end of the motor 583 is sleeved with a gear 584, and the gear 584 is meshed with the gear ring 582. A first spring 585 is connected between the rotating disk 52 and the mounting groove 51.

[0065] When the rotating disk 52 needs to be rotated, the motor 583 is started, and the output end of the motor 583 drives the gear 584 to rotate, the gear 584 drives the gear ring 582 to rotate, the gear ring 582 drives the rotating sleeve 581 to rotate, and the rotating sleeve 581 drives the rotating disk 52 to rotate; when the rotating disk 52 extends out of the mounting groove 51, the first spring 585 is stretched, and when the coolant in the third cooling groove 33 is about to be drained through the drain groove 57, the rotating disk 52 shrinks and enters the mounting groove 51 under the action of the first spring 585.
