Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and specifically relates to a gas-assisted injection mold. Background Technique

[0002] The working principle of a gas-assisted injection mold is that during the injection process, when the plastic melt is injected into the mold cavity to a certain extent, high-pressure gas is injected into the cavity through a special gas injection device. The gas forms pressure inside the melt, pushing the melt to continue filling the mold cavity. Especially for some complex structures that are difficult to fill, the pressure of the gas can help the melt reach these areas better. At the same time, the gas can also play a pressure-holding role during the cooling process, reducing the shrinkage and deformation of the product, and improving the dimensional accuracy and surface quality of the product.

[0003] In the prior art, the material to be processed is first added into the injection molding machine through a hopper, then the injection molding machine is started, the material is melted by the injection molding machine, and the melted material is injected into the mold. Then, through the cooling and shaping of the mold, the required product is manufactured. However, during the long-term use of the mold, a small amount of raw material will remain on the inner wall, which is likely to cause waste of raw material and affect the cleanliness of the mold, thus affecting the quality of the product. And the inner wall residues usually need to be cleaned by workers. On the one hand, it increases the work intensity, and at the same time, the cleaning effect is not good. During the cleaning process, the use of cleaning fluid is required, and the waste materials cleaned need to be dried and then put back into the injection molding machine, which is not conducive to the direct recycling of waste materials.

[0039] It should be noted that a blowing device is installed on one side of the mounting frame 2 corresponding to the second mold 4, so that when the first mold 3 and the second mold 4 are injection-molded, nitrogen is blown in, making the material fit the inner wall better, improving the injection-molding quality, and it is relatively mature in the existing technical field, so there is not much description in this solution.

[0040] Further, as Figure 1 、 Figure 2 and Figure 3 shown, it is specifically noted that the cleaning unit includes:

[0041] A U-shaped fixing plate 10, the U-shaped fixing plate 10 is fixed to the top surface of the mounting frame 2, a hydraulic rod 11 is fixedly installed in the middle of the top surface of the U-shaped fixing plate 10, a U-shaped connecting plate 12 is fixed to the telescopic end of the hydraulic rod 11, a cleaning roller 13 is rotatably installed inside the U-shaped connecting plate 12, a driving motor 14 coaxially connected to the cleaning roller 13 is fixedly installed on one side of the U-shaped connecting plate 12, and a liquid spraying assembly is arranged on the top surface of the U-shaped connecting plate 12.

[0042] It should be noted that the hydraulic rod 11 is used to push the U-shaped connecting plate 12 downward, so that the cleaning roller 13 moves downward close to the first mold 3 and the second mold 4, and then the driving motor 14 is started, so that the cleaning roller 13 rotates inside the U-shaped connecting plate 12, thereby cleaning the inner walls of the first mold 3 and the second mold 4.

[0043] Further, as Figure 3 shown, it is specifically noted that the liquid spraying assembly includes:

[0045] It should be noted that during the rotation and cleaning process of the cleaning roller 13, the special cleaning liquid in the liquid storage box 16 is sprayed on the cleaning roller 13 through the nozzles 15, thereby improving the cleaning ability of the cleaning roller 13; a pouring pipe is fixed to one side of the liquid storage box 16, so that the cleaning liquid can be added to the liquid storage box 16 in time.

[0046] Further, as Figure 1 、 Figure 2 and Figure 4 shown, it is specifically noted that the waste recycling unit includes:

[0047] The spiral conveying cylinder 19 is inclined and arranged above the workbench 1. The feeding end of the spiral conveying cylinder 19 is fixed with a feeding pipe 20. One side of the collection box 8 is fixed with a blanking plate 21. The blanking plate 21 is located above the feeding pipe 20.

[0048] The drying assembly is arranged on the periphery of the spiral conveying cylinder 19. The waste materials are dried by the drying assembly, which is convenient for the direct recycling of the waste materials.

[0049] It should be noted that the cleaned waste materials fall into the collection box 8. The pushing unit pushes them to the blanking plate 21, and then they fall into the feeding pipe 20 along the blanking plate 21. Then the spiral conveying rod inside the spiral conveying cylinder 19 rotates to convey the waste materials. During the conveying process, the drying assembly heats the cylinder, thereby drying the waste materials, and then it is convenient to send the waste materials into the feeding hopper 6, which is convenient for the recycling of the waste materials.

[0052] The heat-insulating sleeves 26 are provided with two and are respectively sleeved on the peripheries of the first spiral heat-conducting pipe 23 and the second spiral heat-conducting pipe 24.

[0053] It should be noted that the heat generated during the heating of the injection molding machine 5 itself is used to heat the liquid inside the second spiral heat-conducting pipe 24. The circulation pump 25 transports the liquid into the first spiral heat-conducting pipe 23, so that the liquid is circulated and heated. When the heated liquid passes through the first spiral heat-conducting pipe 23, it can heat the spiral conveying cylinder 19, thereby facilitating the drying of the waste materials and realizing the utilization of heat; the heat-insulating sleeves 26 reduce the loss of heat.

[0054] Embodiment 2

[0055] On the basis of Embodiment 1, as shown in Figure 2 and Figure 5 shown, it should be specifically described that the pushing unit includes:

[0056] Scraper 27, the scraper 27 is slidably arranged on the top surface of the filter screen 9, one side of the collection box 8 is movably penetrated by a push rod 28, one end of the push rod 28 is fixed to the surface of the scraper 27, and a vibration assembly matched with the push rod 28 is arranged on the top surface of the workbench 1. The vibration assembly includes:

[0057] Fixed frame 29, the fixed frame 29 is fixed on the top surface of the workbench 1, a gear 30 is rotatably connected inside the fixed frame 29, a cam 31 coaxially connected with the gear 30 is rotatably connected on one side of the fixed frame 29, and the cam 31 is matched with the bottom surface of the blanking plate 21;

[0058] Connecting rod 32, the connecting rod 32 is fixed on the outer surface of the push rod 28, a rack rod 33 is fixed at the end of the connecting rod 32, and the rack rod 33 is meshed and driven with the gear 30.

[0059] It should be noted that by pushing the push rod 28, the scraper 27 moves horizontally in the collection box 8, so as to push the waste on the surface of the filter screen 9 to the blanking plate 21, facilitating the blanking work of the waste. During the movement of the push rod 28, the rack rod 33 is driven to move horizontally through the connecting rod 32, thereby driving the gear 30 to rotate on the fixed frame 29, and then driving the cam 31 to rotate. During the rotation process, the cam 31 touches the blanking plate 21, causing the blanking plate 21 to vibrate, so as to facilitate the sliding of the waste and avoid the adhesion of the waste on the blanking plate 21.

[0060] Furthermore, as Figure 5 shown, it should be specifically noted that a connecting block 34 is fixed on one side of one of the fixing rods 7, a U-shaped clamping block 35 is fixed at the end of the connecting block 34, and the U-shaped clamping block 35 is slidably connected with the rack rod 33. The rack rod 33 is limited by the U-shaped clamping block 35, so as to improve the stability of the rack rod 33 during the horizontal movement process.

[0061] Furthermore, as Figure 1 、 Figure 2 and Figure 4 shown, it should be specifically noted that a support frame 36 is fixed on the outer surface of one of the heat insulation sleeves 26 to support the spiral conveying cylinder 19; a liquid inlet pipe 37 is fixed on the outer surface of the second spiral heat conduction pipe 24, and a valve is fixedly installed on the outer surface of the liquid inlet pipe 37, facilitating the filling of the liquid in the first spiral heat conduction pipe 23 and the second spiral heat conduction pipe 24; a drain pipe 38 is fixed on the bottom surface of the collection box 8, and a waste liquid bucket 39 is placed corresponding to the drain pipe 38 inside the workbench 1. The filtered waste and waste liquid flow through the drain pipe 38 to the waste liquid bucket 39 for collection, facilitating the centralized treatment of the waste liquid.

[0062] This embodiment also has the following working process: Move the second mold 4 to one side of the first mold 3, and then push the U-shaped connecting plate 12 downward through the hydraulic rod 11, so that the cleaning roller 13 moves downward to approach the first mold 3 and the second mold 4. Then start the driving motor 14 to make the cleaning roller 13 rotate within the U-shaped connecting plate 12, thereby cleaning the inner walls of the first mold 3 and the second mold 4. During the rotation and cleaning process of the cleaning roller 13, the special cleaning liquid in the liquid storage box 16 is sprayed onto the cleaning roller 13 through the nozzle 15, thereby improving the cleaning ability of the cleaning roller 13. The waste after cleaning falls into the collection box 8, and then by pushing the push rod 28, the scraper 27 moves horizontally within the collection box 8, thereby pushing the waste on the surface of the filter screen 9 to the blanking plate 21, facilitating the blanking work of the waste. During the movement of the push rod 28, the rack rod 33 is driven to move horizontally through the connecting rod 32, thereby driving the gear 30 to rotate on the fixed frame 29, and then driving the cam 31 to rotate. During the rotation, the cam 31 touches the blanking plate 21, causing the blanking plate 21 to vibrate, thereby facilitating the sliding of the waste and avoiding the adhesion of the waste on the blanking plate 21. The waste falls into the feed pipe 20, and then the spiral conveyor rod inside the spiral conveyor cylinder 19 rotates to convey the waste. During the conveying process, the liquid heated by the injection molding machine 5 is conveyed into the first spiral heat conduction pipe 23 through the circulating pump 25, so that the liquid is circulated and heated. When the heated liquid passes through the first spiral heat conduction pipe 23, it can heat the spiral conveyor cylinder 19, thereby facilitating the drying of the waste. The heat loss is reduced through the heat preservation sleeve 26. The cylinder is heated by the drying component to dry the waste, and then it is convenient to directly feed the waste into the feed hopper 6, facilitating the recycling of the waste.

[0063] The hydraulic rod 11, the driving motor 14, the water pump 17 and the circulating pump 25 can be purchased on the market and are separately equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
