Description

Technical Field

[0001] The invention relates to the technical field of nozzle removal equipment for injection molding products, and in particular to nozzle removal equipment for injection molding production of plastic storage boxes. Background Art

[0002] In the injection molding process of plastic products, the sprue (also called gate or runner) is the main channel for molten plastic to enter the mold cavity. For products such as plastic storage boxes, the sprue needs to be removed after injection molding to ensure the quality and appearance of the finished product.

[0003] After searching, a Chinese patent with patent publication number CN118024515A is found, which is a water inlet removal device for injection molding production, including: a collecting component, a driving component, a receiving component and a supporting component, the driving component is fixedly installed on the top of the supporting component, the receiving component is slidably connected to the top of the supporting component, and the collecting component is slidably installed on the inner bottom end of the supporting component; the driving component is used to provide power for the water inlet processing of the injection molded product, and drive the collecting component to operate to collect the injection molded product.

[0004] Although the above patent can realize the automatic removal of the sprue, it lacks the function of removing the flash of the plastic storage box. In the injection molding process, the generation of flash is inevitable, so it is also necessary to remove these flashes to ensure the quality and appearance of the finished product. Since the above patent cannot automatically remove the flash, in actual production, additional flash removal equipment is required to complete the trimming of the entire plastic storage box. This not only increases the equipment cost, but also requires the plastic storage box to be transferred back and forth between the sprue removal equipment and the flash removal equipment, which will lead to a decrease in production efficiency.

Detailed implementation manners

[0030] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0031] See Figures 1 - 10, A plastic storage box injection molding production gate removal device, including a frame 1. A workbench 2 is connected to the top of the frame 1. An opening 20 is opened in the middle of the workbench 2. Electric slide rails 3 are installed on both the front and rear sides inside the opening 20. An installation plate 4 is connected between the sliders of the two electric slide rails 3. A rotary placement table 5 for placing the storage box 24 is provided on the top of the installation plate 4. The rotary placement table 5 includes a motor one 51 installed in the middle of the top of the installation plate 4. A placement plate 52 is connected to the output shaft of the motor one 51. Guide grooves 53 are opened on both the front and rear sides and the left and right sides of the placement plate 52. L-shaped sliding blocks 54 are slidably connected in the guide grooves 53. A sliding rod 55 is slidably connected to the sliding block 54. A positioning plate 56 for supporting and positioning the storage box 24 is connected to the sliding rod 55. A compression spring 57 is sleeved on the sliding rod 55. The two ends of the compression spring 57 are respectively connected to the positioning plate 56 and the sliding block 54. The upper part of the positioning plate 56 is bent towards the direction close to the sliding block 54 to facilitate placing the storage box 24 downward outside the four positioning plates 56. A fastening bolt 58 for locking the sliding block 54 on the placement plate 52 is provided on the sliding block 54. A gantry 6 is connected to the top right of the workbench 2. A tool 8 for removing the gate 25 is connected to the gantry 6 through a height adjustment component one. The height adjustment component one includes a screw rod one 71 rotatably connected to the middle of the top of the gantry 6. A nut one 72 is threadedly connected to the screw rod one 71. A U-shaped plate 73 is connected to the bottom of the nut one 72. A sliding rod 74 is slidably connected to the lower part of the U-shaped plate 73. A lifting block 75 is connected to the bottom end of the sliding rod 74. A return spring 76 is sleeved on the sliding rod 74. The two ends of the return spring 76 are respectively connected to the lifting block 75 and the U-shaped plate 73. A telescopic rod 77 is connected to the inner top surface of the gantry 6. The telescopic rod 77 is connected to the lifting block 75. The tool 8 includes a U-shaped block 81 connected to the right side surface of the lifting block 75. A V-shaped cutting tool 82 is connected inside the U-shaped block 81. Two inclined rods 83 are symmetrically connected to the front and rear of the right side of the U-shaped block 81. An installation frame 9 is connected to the workbench 2. The installation frame 9 is located to the left of the gantry 6. A rotary lifting press tool 10 for pressing and fixing the storage box 24 on the placement plate 52 is provided on the installation frame 9. The rotary lifting press tool 10 includes a motor two 101 installed on the inner top surface of the installation frame 9. An electric push rod one 102 is installed on the output shaft of the motor two 101. A pressing block 103 is connected to the push rod of the electric push rod one 102. A rotary ring 104 is installed on the outer shell of the electric push rod one 102. An annular sliding groove for guiding the rotation of the rotary ring 104 is opened on the installation frame 9. A profiling plate 11 is bolted to the bottom of the rotary ring 104. The shape and size of the profiling plate 11 are the same as those of the storage box 24. A through hole matching the electric push rod one 102 is opened on the profiling plate 11. A sliding groove is opened on the front side of the inner top surface of the installation frame 9. A sliding block is slidably connected in the sliding groove. A contact plate 12 located in front of the profiling plate 11 is connected to the bottom of the sliding block. A support spring 13 is connected between the contact plate 12 and the installation frame 9 to drive the contact plate 12 to keep in contact with the profiling plate 11.A contact wheel 19 is rotatably connected to the rear side of the contact plate 12. By means of the contact wheel 19, the frictional force between the contact plate 12 and the profiling plate 11 can be reduced, so as to reduce the wear of the contact plate 12 and the profiling plate 11, thereby prolonging the service life of the contact plate 12 and the profiling plate 11. Two upper and lower guide sleeves 15 are connected to the contact plate 12 through a height adjustment component II. A connecting rod 16 is slidably arranged in the guide sleeve 15. The rear end of the connecting rod 16 is connected with a cutting tool 17 for removing flash 26. A fastening bolt 18 for locking the connecting rod 16 is arranged at the top of the guide sleeve 15. An infrared sensor 41 is arranged between the bottom of the mounting plate 4 and the bottom of the workbench 2. The transmitter of the infrared sensor 41 is installed in the middle of the bottom of the mounting plate 4, and the receiver of the infrared sensor 41 is installed at the bottom of the workbench 2. The receiver of the infrared sensor 41 is located directly below the profiling plate 11.,

[0032] First, loosen the fastening bolt 58 to release the locking of the sliding block 54. Then, move the sliding block 54, and pull the positioning plate 56 to move by compressing the spring 57, so as to adjust the position where the positioning plate 56 is located to adapt to plastic storage boxes 24 of different specifications and sizes. Tighten the fastening bolt 58 to lock the sliding block 54 again. Then, invert the plastic storage box 24 on the placing plate 52. The plastic storage box 24 pushes the positioning plate 56 to move inward to compress the spring 57. Through the cooperation of the surrounding positioning plates 56 and the spring 57, not only can the plastic storage box 24 be centered, but also the plastic storage box 24 can be supported and fixed on the placing plate 52. Subsequently, control the electric slide rail 3 to drive the mounting plate 4 to drive the rotary placing table 5 to move leftward, so as to drive the plastic storage box 24 to move leftward. When the plastic storage box 24 contacts the inclined rod 83, the plastic storage box 24 continues to push the inclined rod 83 upward, so that the U-shaped block 81 drives the V-shaped cutting tool 82 and the lifting block 75 to move upward, compressing the return spring 76. Through the elastic force of the return spring 76, it is ensured that the U-shaped block 81 closely adheres to the bottom of the inverted plastic storage box 24, so as to ensure that the V-shaped cutting tool 82 closely adheres to the bottom of the inverted plastic storage box 24, and further ensure that the V-shaped cutting tool 82 can smoothly cut off the water inlet 25 at the bottom of the plastic storage box 24. During the leftward movement of the plastic storage box 24, the water inlet 25 at its bottom contacts the V-shaped cutting tool 82, and the water inlet 25 is cut off by the V-shaped cutting tool 82. Compared with a flat cutting tool, the V-shaped cutting tool 82 can better fit the shape of the water inlet 25, so as to achieve more accurate cutting. Compared with a wide-edge cutting tool, the V-shaped cutting tool 82 can quickly cut off the water inlet 25 with less force.

[0033] After the plastic storage box 24 with the sprue 25 removed continues to move leftward and disengages from the U-shaped block 81, under the reset action of the return spring 76, the lifting block 75 is pushed to drive the U-shaped block 81 to move downward and reset, and the V-shaped cutting knife 82 and the inclined rod 83 move downward and reset accordingly. The plastic storage box 24 after the sprue 25 is removed continues to move leftward to directly below the pressing block 103 and is aligned with the profiling plate 11 directly below it. During this process, the two upper and lower flash edges 26 on the bottom of the inverted plastic storage box 24 come into contact with the upper and lower cutting knives 17 respectively and are cut off by the cutting knives 17. The mounting plate 4 drives the plastic storage box 24 to move leftward to directly below the profiling plate 11 through the rotary placement table 5, and at the same time drives the transmitter of the infrared sensor 41 to move leftward to directly above the receiver. When the receiver of the infrared sensor 41 receives the infrared beam transmitted by the transmitter, the infrared sensor 41 sends a signal to the controller (the controller is not shown in the figure, and the controller is prior art and will not be elaborated here). After receiving the signal, the controller first controls the electric slide rail 3 to close, then controls the electric push rod 102 to drive the pressing block 103 to move downward to press and fix the plastic storage box 24 on the placement plate 52, and then controls the motor 51 and the motor 101 to work synchronously, so as to drive the profiling plate 11 and the plastic storage box 24 to rotate synchronously. When the profiling plate 11 rotates, it pushes the contact plate 12 to move forward and compress the support spring 13. Through the support spring 13, the contact plate 12 can always be kept in contact with the profiling plate 11, so as to ensure that the cutting knife 17 can always be in contact with the flash edge 26 to cut off the flash edge 26. The rotation of the plastic storage box 24 enables the entire circle of the flash edge 26 to come into contact with the cutting knife 17 and be completely cut off. In this way, this device can not only automatically remove the sprue 25, but also automatically remove the flash edge 26, realizing the trimming of the entire plastic storage box 24 and improving the production efficiency.

[0034] After the flash 26 is removed, first control the electric push rod 102 to drive the pressing block 103 to move upward and separate from the plastic storage box 24. Then control the electric slide rail 3 to drive the mounting plate 4 to drive the rotary placement table 5 to continue moving to the left, thereby driving the plastic storage box 24 to continue moving to the left away from the pressing block 103 and the profiling plate 11. Then remove the trimmed plastic storage box 24 from the rotary placement table 5. Finally, control the electric slide rail 3 to drive the mounting plate 4 to drive the rotary placement table 5 to move to the right to reset for the next round of trimming operation of the plastic storage box 24. Rotating the first screw rod 71 can drive the first nut 72 to drive the U-shaped plate 73 to lift and lower, thereby driving the lifting block 75 to lift and lower through the return spring 76, and further driving the cutter 8 to lift and lower to adjust the height of the cutter 8 to adapt to plastic storage boxes 24 of different heights. The height of the upper and lower guide sleeves 15 can be adjusted through the second height adjustment component, thereby adjusting the height of the cutting knife 17 to adapt to plastic storage boxes 24 of different heights. Loosening the fastening bolt 18 can release the locking of the connecting rod 16. Subsequently, the connecting rod 16 can be moved back and forth, thereby adjusting the front and rear positions of the cutting knife 17 to adapt to plastic storage boxes 24 of different specifications and sizes. Tightening the fastening bolt 18 can re-lock the connecting rod 16. In specific implementation, profiling plates 11 of different specifications and sizes are designed, and by replacing profiling plates 11 of different specifications and sizes, plastic storage boxes 24 of different specifications and sizes can be adapted.

[0035] See Figure 8 , Figure 10 and Figure 11 , the second height adjustment component includes a second screw rod 141 fixedly connected to the contact plate 12. Two second nuts 142 are threadedly connected to the second screw rod 141. Two lifting rings 143 are slidably sleeved on the second screw rod 141. The two lifting rings 143 are respectively rotatably connected to the two second nuts 142. Notches 145 are formed on both the left and right sides of the second screw rod 141. An inner diamond block 144 matched with the notch 145 is connected inside the lifting ring 143. Through the cooperation of the notch 145 and the inner diamond block 144, the lifting of the lifting ring 143 is guided to ensure that the lifting ring 143 can only lift and lower and cannot rotate. The two guide sleeves 15 are respectively connected to the right outer walls of the two lifting rings 143. Rotating the second nut 142 can cause the second nut 142 to lift and lower. The lifting and lowering of the second nut 142 drives the lifting ring 143 to lift and lower to adjust the height of the guide sleeve 15, thereby adjusting the height of the cutting knife 17 to adapt to the storage box 24 of different heights.

[0036] See Figure 8 , an electric push rod 21 is installed in the middle of the top of the placement plate 52. A supporting block 22 for supporting the storage box 24 is connected to the push rod of the electric push rod 21.

[0037] After the placement plate 52 drives the storage box 24 to move leftward to directly below the pressing block 103, the second electric push rod 21 and the supporting block 22 will move to directly below the pressing block 103 accordingly. While the controller controls the first electric push rod 102 to drive the pressing block 103 to move downward, the controller also controls the second electric push rod 21 to drive the supporting block 22 to move upward to contact the storage box 24. Through the coordinated action of the pressing block 103 and the supporting block 22, centering of the storage box 24 can be achieved, ensuring its position on the placement plate 52 is more stable. This can not only prevent the center of the storage box 24 from shifting due to flinging during rotation, improve the accuracy of flash 26 removal, but also effectively avoid the storage box 24 being deformed by the pressing block 103. After the flash 26 is removed, the controller controls the second electric push rod 21 to drive the supporting block 22 to move downward to disengage from the storage box 24.

[0038] See Figure 3 , a rubber block 23 is connected to the bottom of the pressing block 103 and the top of the supporting block 22. Through the rubber block 23, it is possible to avoid the pressing block 103 and the supporting block 22 directly and rigidly squeezing the storage box 24, so as to buffer and protect the storage box 24 and avoid damage to the storage box 24.

[0039] The above-described embodiments only represent the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention.
