Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0019] Please refer to Figure 1-6 , the present application provides a remote control shell part injection molding device, including a lower mold 10 and an upper mold 20 coupled with the lower mold 10. A water cooling channel 30 is opened in the lower mold 10. A water flow driving assembly 40 is rotatably penetrated through the side wall of the water cooling channel 30. One end of the water flow driving assembly 40 is connected with a blowing mechanism 50. An air cooling channel 60 is formed after the lower mold 10 and the upper mold 20 are closed. The blowing mechanism 50 is communicated with the air cooling channel 60. Specifically, during the injection molding cooling process, the water cooling channel 30 is communicated with an external water circulation device to enable the internal water of the water cooling channel 30 to circulate, so that the flowing water will drive the water flow driving assembly 40 to operate, and then the water cooling driving assembly 40 will drive the blowing mechanism 50 to operate. The blowing mechanism 50 will then convey air into the air cooling channel 60, so as to realize simultaneous water cooling and air cooling, improve the cooling efficiency, and achieve the purpose of energy saving at the same time.

[0020] Refer to Figure 2 and 6 , the lower mold 10 includes a mold base 110. An installation cavity 120 is opened at the top of the mold base 110. A shell part injection molding die 130 is installed in the installation cavity 120. When setting, several screws are slidably penetrated through the shell part injection molding die 130. At the same time, several screw holes are opened at the bottom of the installation cavity 120. The several screw holes are respectively arranged corresponding to the several screws to fix the shell part injection molding die 130 in the installation cavity 120.

[0021] Refer to Figure 3, the water cooling channel 30 includes a first channel 310 and a second channel 320 opened in the mold base 110. The inlet ends of the first channel 310 and the second channel 320 are both connected with connectors 330. The outlet ends of the first channel 310 and the second channel 320 are connected with the same U-shaped pipe 340. The water flow driving assembly 40 is rotatably arranged through the side wall of the U-shaped pipe 340. Specifically, through the two connectors 330, the first channel 310 and the second channel 320 are connected with the external water circulation device, so that water flows through the first channel 310, the U-shaped pipe 340 and the second channel 320 in sequence. When the water flows through the U-shaped pipe 340, it will drive the water flow driving assembly 40 to operate.

[0022] Refer to Figure 2 , 3 and 6, the water flow driving assembly 40 includes a rotating shaft 410 rotatably arranged through the side wall of the U-shaped pipe 340. One end of the rotating shaft 410 is provided with an impeller 420. The impeller 420 is located inside the U-shaped pipe 340. The blowing mechanism 50 is connected to the other end of the rotating shaft 410. When arranged, the water in the U-shaped pipe 340 flows rapidly, which will drive the impeller 420 to rotate. The impeller 420 drives the blowing mechanism 50 to operate through the rotating shaft 410, so as to achieve the purpose of energy saving. Further, the blowing mechanism 50 includes fan blades 510 and a mounting pipe 520. The fan blades 510 are fixedly connected to one end of the rotating shaft 410. The mounting pipe 520 is fixedly installed on the side wall of one end of the U-shaped pipe 340. The fan blades 510 are located inside the mounting pipe 520. The mounting pipe 520 is provided with air inlet holes 530. The top of the mounting pipe 520 is communicated with an air inlet pipe 540. The air cooling channel 60 is communicated with the air inlet pipe 540. It should be noted that the fan blades 510 rotate inside the mounting pipe 520, so that the air inside the mounting pipe 520 flows. At the same time, the outside air enters the mounting pipe 520 through the air inlet holes 530, and the air inside the mounting pipe 520 enters the air flow channel through the air inlet pipe 540, so as to reduce the temperature of the shell injection molding die 130.

[0023] Refer to Figure 2 and 4, the air-cooling channel 60 includes a semi-circular inlet 610 and a semi-circular outlet 620 opened at the top of the mold base 110, and a first semi-circular channel 630 opened at the top of the shell injection molding die 130; it also includes a second semi-circular channel 640 opened at the bottom of the upper mold 20. The two ends of the first semi-circular channel 630 are respectively communicated with the semi-circular inlet 610 and the semi-circular outlet 620. The second semi-circular channel 640 is closed with the semi-circular inlet 610, the semi-circular outlet 620 and the first semi-circular channel 630 to form an air flow channel. The air inlet pipe 540 is communicated with the inlet end of the air flow channel. When specifically set, when the upper mold 20 and the lower mold 10 are closed, the second semi-circular channel 640 is closed with the semi-circular inlet 610, the semi-circular outlet 620 and the first semi-circular channel 630, so as to form an air flow channel. Thus, air enters the air flow channel through the air inlet pipe 540 to complete the cooling of the shell injection molding die 130. Further, a plurality of molding cavities 140 are opened at the top of the shell injection molding die 130, and the first semi-circular channel 630 is arranged around the plurality of molding cavities 140. It should be noted that an injection hole is provided at the central part of the upper mold 20, and a connection hole is opened at the central part of the shell injection molding die 130. At the same time, a flow hole is opened at the top of the shell injection molding die 130. The flow hole is communicated with the connection hole and is also communicated with the molding cavity 140, so that the molding material flows into the molding cavity 140. And the first semi-circular channel 630 is arranged around the plurality of molding cavities 140, which can improve the cooling effect on the molding cavity 140.

[0024] Refer to Figure 5 , a thimble assembly 70 slidably penetrates through the bottom of each of the plurality of molding cavities 140. A reset assembly 80 is installed at the bottom of the thimble assembly 70, and the reset assembly 80 is connected to the bottom of the mold base 110. The thimble assembly 70 includes a plurality of thimbles 710. The plurality of thimbles 710 slidably penetrate through the bottom of the plurality of molding cavities 140. The bottoms of the plurality of thimbles 710 are fixedly connected to the same lifting plate 720. The reset assembly 80 is connected to the lifting plate 720. Specifically, after the upper mold 20 and the lower mold 10 are closed, the thimbles 710 will be received inside the bottom of the molding cavity 140, and the tops of the thimbles 710 are flush with the bottom of the molding cavity 140, so as to avoid the thimbles 710 affecting the product molding. At the same time, after the product is molded and the mold is opened, the thimbles 710 will push the product upward to facilitate the removal of the molded product.

[0025] Refer to Figure 5, the reset component 80 includes several positioning rods 810. The several positioning rods 810 are all fixedly installed at the bottom of the die base 110. Springs 820 are sleeved on the several positioning rods 810. The lifting plate 720 is slidably sleeved on the several positioning rods 810. The two ends of the several springs 820 are respectively connected to the bottom of the die base 110 and the bottom of the lifting plate 720. During setting, the upper die 20 and the lower die 10 are closed, and the upper die 20 presses the ejector pin 710 downward, so that the lifting plate 720 moves downward, compressing the springs 820. Then, when the mold is opened, the springs 820 drive the lifting plate 720 to reset, so as to drive the ejector pin 710 to reset. The positioning rods 810 achieve the purpose of limiting the springs 820.

[0026] When this remote control shell injection molding device is working: the upper die 20 and the lower die 10 are closed, the ejector pin 710 is compressed into the bottom of the molding cavity 140, and at the same time the springs 820 are compressed. Then, molding materials can be injected into the molding cavity 140 of the lower die 10 through the upper die 20. After the injection molding is completed, cooling water is conveyed into the first channel 310, the U-shaped pipe 340 and the second channel 320 through the existing water circulation device through the joint 330, so that the cooling water circulates, thereby achieving the purpose of dissipating heat from the periphery of the shell injection molding die 130. When the water flow passes through the U-shaped pipe 340, it will drive the impeller 420 in the U-shaped pipe 340 to rotate. The impeller 420 drives the rotating shaft 410 to rotate, so that the rotating shaft 410 drives the fan blades 510 in the installation pipe 520 to rotate, so that the air in the installation pipe 520 flows. The air moves through the air inlet pipe 540 into the air flow channel, so as to achieve the purpose of dissipating heat from the shell injection molding die 130, thereby improving the heat dissipation effect. After the heat dissipation is completed and the product is formed, the cooling water circulation can be stopped. Finally, the mold is opened, the springs 820 reset, driving the lifting plate 720 to reset, so that the ejector pin 710 ejects the product, and the product can be taken out.

[0027] It should be noted that the specific model specifications of the lower die 10 and the upper die 20 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0028] The power supply and its principle of the lower die 10 and the upper die 20 are clear to those skilled in the art, and will not be elaborated here.

[0029] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
