Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, in particular to a cooling device for injection molded products. Background Art

[0002] An injection molding machine, also known as an injection molding machine or injection machine, is the primary molding equipment used to create plastic products of various shapes using plastic molding molds from thermoplastics or thermosetting plastics. The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to eject and fill the mold cavity.

[0003] During the injection molding process, the temperature of the product in the mold is kept high during the molding process, and the molded parts usually need to be cooled after being taken out. A shell-type injection molded part needs to be placed on a support block that matches its inner cavity during cooling to prevent it from shrinking and deforming. The method of manually placing the workpiece to air dry is inefficient. Therefore, in the prior art, a robotic arm is usually used to remove the injection molded workpiece and then place it on the support block. Since the injection molded workpiece needs to have sufficient air cooling time, the robotic arm can only take the materials in turn and place them on the plate, and then take the workpieces in turn. Since the position of each support block is different, multiple control commands need to be set for the robotic arm to reach their respective corresponding points, which is relatively complicated.

However, the specific implementation methods and embodiments described below are only for illustrative purposes and are not intended to limit the present invention.

[0021] When the injection molding machine is in operation, the product in the mold is kept at a relatively high temperature during the molding process, and the injection molded parts usually need to be cooled after being taken out. A shell-type injection molded part needs to be placed on a support block that matches its inner cavity during cooling to prevent it from shrinking and deforming. The method of manually placing the workpiece for air drying is inefficient and has high labor costs. Therefore, in the prior art, a robotic arm is usually used to remove the injection molded workpiece and place it on the support block. Since the injection molded workpiece needs to have enough air cooling time, the robotic arm can only take the material in turn and place it on a plate, and then take the workpiece in turn. Since each support block has a different position, multiple control commands need to be set for the robotic arm to reach their respective corresponding points, which is relatively complicated. When the robotic arm takes the material in turn, the injection molding machine needs to stop running and wait for it to unload the material, which wastes time. In order to solve the above technical problems, such as Figure 1As shown, the present invention relates to a cooling device for injection molded products, specifically, comprising a supporting base 1, wherein a rotary chute is provided on the top of the supporting base 1, wherein the rotary chute comprises a first chute 2, a second chute 3, a third chute 4, and a fourth chute 5 connected in sequence, wherein the first chute 2, the second chute 3, the third chute 4, and the fourth chute 5 form a square structure, wherein a first reversing station 6 is provided between the first chute 2 and the fourth chute 5, a second reversing station 7 is provided between the first chute 2 and the second chute 3, and the first A third reversing station 8 is provided between the second chute and the third chute, a fourth reversing station 9 is provided between the third chute 4 and the fourth chute 5, support blocks 10 are evenly spaced in the rotary chute, and the support blocks 10 are used to sleeve the injection molded workpiece 11, and the support base 1 is provided with a first cylinder 12 on one side of the first chute 2, the piston rod of the first cylinder 12 is directed toward the side away from the second chute 3 and is connected to a first push block 13, the first push block 13 is used to push the support block 10 located in the first chute 2 to the second The reversing station 7, the support base 1 is provided with a second cylinder 14 on one side of the second chute 3, the piston rod of the second cylinder 14 is directed toward the side away from the third chute 4 and is connected to a second push block 15, the second push block 15 is used to push the support block 10 located in the second chute 3 to the third reversing station 8, the support base 1 is provided with a third cylinder 16 on one side of the third chute 4, the piston rod of the third cylinder 16 is directed toward the side away from the fourth chute 5 and is connected to a third push block 17, the third push block 17 is used to push the support block 10 located in the second chute 3 to the third reversing station 8.

[0022] Specifically, the first reversing station 6 is also the loading station, and the position of the support block 10 adjacent to the first annular station in the fourth chute 5 is the unloading station 20. After removing the injection-molded workpiece 11, the robotic arm (not shown in the figure) puts it on the support block 10 located at the loading station, and then removes the injection-molded workpiece 11 located at the unloading station 20. It only needs to complete the actions of taking, placing, and taking materials and reciprocating between the three stations, which greatly simplifies the control commands. At the same time, the distance between the loading station and the unloading station 20 is small, the moving distance of the robotic arm is small, and the overall loading and unloading efficiency is greatly improved. In addition, the injection-molded workpiece 11 on each support block 10 is fully cooled while moving in the rotary trough.

[0025] In this embodiment, it is further preferred that Figure 4 As shown, cooling water is provided in the rotary trough, and the supporting base 1 is provided with a water inlet 29 and a water outlet 30 on both sides. The water inlet 29 is connected to the side of the second chute 3, and the water outlet 30 is connected to the bottom surface of the fourth chute 5. Cooling water is injected into the rotary trough to accelerate the cooling and shaping efficiency.

[0026] In this embodiment, it is further preferred that the support base 1 is provided with a protrusion on the side corresponding to the first chute 2, and the protrusion is provided with a blanking hole 31 running through the upper and lower parts. The support base 1 is provided with a blanking cylinder 32, and the axis direction of the piston rod of the blanking cylinder 32 coincides with the extension direction of the fourth chute 5, so that the robot arm only needs to adjust and move along one axis when unloading. The piston rod of the blanking cylinder 32 is connected to a blanking push block 33, and a material receiving box placement plate 34 is provided below the protrusion. The workers take and place the material receiving box on the material receiving box placement plate 34, and the robot places the injection molded workpiece 11 that has been removed after cooling in front of the material unloading push block 33, and is driven by the unloading cylinder 32 to push it to the blanking hole 31. The blanking hole 31 is preferably provided with a guide slope, and the injection molded workpiece 11 can slide into the material receiving box along the guide slope, adding a material unloading action to the robot arm, thereby improving the material receiving efficiency. In addition, this station is close to the loading station, the robot arm moves a short distance, and the loss is also small. The worker only needs to replace the material receiving box regularly.

[0027] Furthermore, limiting baffles 35 are symmetrically provided on both sides of the blanking hole 31 , and the limiting baffles 35 are used to limit and guide the injection molded workpiece 11 to ensure that it falls into the blanking hole 31 .

[0028] Furthermore, a roller 36 is provided at each of the four corners of the bottom of the supporting base 1. The arrangement of the roller 36 facilitates the transfer of the device.

[0029] Specific working principle: Move the device to the side of the injection molding machine. During operation, the support blocks 10 in the rotary groove are sleeved with injection molded workpieces 11 for circulation. The robotic arm (not shown in the figure) takes the injection molded workpiece 11 from the injection molding machine and sleeves it on the support block 10 located at the first reversing station. Then the robotic arm moves to the unloading station 20. At the same time, the first cylinder 12 drives the first push block 13 to pull back so that the support block 10 in the first chute 2 moves to the second reversing station. Then the double guide rod cylinder 22 drives the pressing plate to press down so that the injection molded workpiece 11 fits more closely on the support block 10. The shaping effect is ensured on the block 10, and then the second cylinder 14, the third cylinder 16, and the fourth cylinder 18 are operated in sequence to make the injection molded workpiece 11 in the entire rotary groove complete the circulation of one station. When a support block 10 moves to the unloading station 20, the robot arm moves to the unloading station 20 to remove the injection molded workpiece 11. After removing the workpiece, the robot arm moves it to the front side of the unloading push block 33, and the unloading cylinder 32 is operated to push it into the unloading hole 31 so that it falls into the material receiving box. At the same time, the robot arm moves to the injection molding machine to continue to take the material, and operates reciprocatingly to replace manual labor.
