[0003] However, in the prior art, products molded in injection molding machine molds are usually ejected upward or downward by a driving source. However, due to the "adhesion" between the mold and the product, this method easily leads to "bumps" on the product surface and "particles" adhering to the inner wall of the mold. This requires subsequent cleaning and scraping of the product surface to make the product surface smooth. The "particles" adhering to the inner wall of the mold will also affect the production quality of the next injection-molded product, and staff are required to clean it, which makes it difficult to meet the needs of staff.

[0020] Example 2 Please refer to Figure 5 As shown, the mold mechanism 3 includes rotating rods 301 rotatably installed on the left and right sides of the protective box 103, and a shell 302 is fixedly connected between the two groups of rotating rods 301.

A second drive motor 303 that drives one group of rotating rods 301 to rotate is provided on the outside of the protective box 103.

[0021] Those skilled in the art can understand that the output end of the second drive motor 303 can drive the shell 302, the upper cover 304 and the lower cover 306 to flip and rotate as a whole, and by controlling the rotation of the output end of the third drive motor 305, the opening and closing of the upper cover 304 is achieved, and by controlling the rotation of the output end of the fourth drive motor 307, the opening and closing of the lower cover 306 is achieved.

[0023] Please refer to Figure 7 As shown, a third electric push rod 406 is fixedly installed on the top of the movable plate 405, and the output end of the third electric push rod 406 passes through the top wall of the movable plate 405 and is fixedly connected to the middle part of the top of the ejection plate 407.

There is a gap between the first scraper 409 and the ejection plate 407 in the front-to-back direction.

[0024] Those skilled in the art will understand that, by driving the second screw 402 to rotate through the output end of the second stepper motor 404, the movable plate 405 is caused to reciprocate horizontally left and right, thereby driving the ejection plate 407 and the first scraper 409 to reciprocate horizontally left and right; and by controlling the extension or contraction of the output ends of the third electric push rod 406 and the fourth electric push rod 408 respectively, the ejection plate 407 and the first scraper 409 are driven to move up and down.

[0025] Example 4 Please refer to Figure 6 and Figure 8 As shown, the auxiliary mechanism 5 includes a third screw rod 502 and a third guide rod 503, and the second fixed blocks 501 are fixedly installed at both ends of the third guide rod 503.

The outer surface of the third guide rod 503 is slidably connected to a movable plate 505, and the movable plate 505 is threadedly connected to the outer surface of the third screw rod 502. A third stepping motor 504 for driving the third screw rod 502 to rotate is provided on the outer side wall of one group of second fixed blocks 501.

[0026] Please refer to Figure 9 As shown, the auxiliary mechanism 5 also includes a fifth drive motor 506 and a rotating member 507. The fifth drive motor 506 is fixedly installed at the bottom of the movable plate 505. The bottom of the rotating member 507 is fixedly connected to the output end of the fifth drive motor 506. Two groups of first fixed rods 508 are fixedly connected to the rotating member 507. Both ends of the first fixed rod 508 are welded to the first connecting block 509. A first threaded rod 510 is rotatably connected between the two groups of first connecting blocks 509. A first servo motor 511 that drives the first threaded rod 510 to rotate is installed on the outer wall of one group of first connecting blocks 509. The threads opened at both ends of the first threaded rod 510 rotate in opposite directions, and two groups of first clamping members 512 are slidably connected to the first fixed rod 508. The two groups of first clamping members 512 are respectively threadedly connected to the two ends of the outer surface of the first threaded rod 510.

[0027] Please refer to Figure 9As shown, two groups of second fixed rods 513 are welded on the rotating member 507, and the outer surfaces of the two groups of second fixed rods 513 are slidably connected with two groups of second clamping members 517. The height of the second fixed rods 513 is lower than the height of the first fixed rods 508, and the height of the cross plates of the two groups of second clamping members 517 is the same as the height of the cross plates of the two groups of first clamping members 512. Second connecting blocks 514 are fixedly installed at both ends of the second fixed rods 513, and a second threaded rod 515 is rotatably connected between the two groups of second connecting blocks 514. The two groups of second connecting blocks 514 are respectively threadedly connected to the two ends of the second threaded rod 515, and the threads opened at both ends of the second threaded rod 515 have opposite rotation directions. The outer side of one group of second connecting blocks 514 is fixedly connected to a second servo motor 516 that drives the second threaded rod 515 to rotate.

[0028] Those skilled in the art can understand that, by driving the third screw rod 502 to rotate through the output end of the third stepper motor 504, the movable plate 505 is caused to reciprocate horizontally left and right, thereby driving the two groups of first clamping members 512 and the two groups of second clamping members 517 to reciprocate horizontally left and right; and by driving the first threaded rod 510 to rotate through the output end of the first servo motor 511, the two groups of first clamping members 512 are moved closer to or away from each other, and by driving the second threaded rod 515 to rotate through the output end of the second servo motor 516, the two groups of second clamping members 517 are moved closer to or away from each other; and under the action of the output end of the fifth drive motor 506, the rotating member 507 is rotated, thereby realizing that the two groups of first clamping members 512 and the two groups of second clamping members 517 all "draw circles" with the center of the rotating member 507 as the center.

[0029] Example 5 Please refer to Figure 10 and Figure 11 As shown, the second cleaning mechanism 6 includes a fifth electric push rod 601 rotatably connected to the left side of the protective box 103, and a driven wheel 604 is fixedly installed on the outer surface of the fifth electric push rod 601. The left side of the protective box 103 is also connected to a fourth drive motor 602, and the output end of the fourth drive motor 602 is fixedly connected to the drive wheel 603. The drive wheel 603 is connected to the driven wheel 604 through a belt 605. The output end of the fifth electric push rod 601 extends to the inside of the protective box 103 and is fixed to the fixed frame. The outer side of 606 is fixedly connected, and a fourth screw rod 607 is rotatably connected inside the fixed frame 606. A lifting member 610 is threadedly connected to the fourth screw rod 607. A second scraper 611 is fixedly installed on the outer side of the lifting member 610. A fourth guide rod 608 is also welded to the inside of the fixed frame 606. The lifting member 610 is slidably connected to the fourth guide rod 608. The top of the fourth screw rod 607 is fixedly connected to the output end of the fourth stepper motor 609, and the fourth stepper motor 609 is arranged on the top of the fixed frame 606.

[0030] Two groups of first electric push rods 104 are fixedly installed on the top right side of the protective box 103. The output ends of the two groups of first electric push rods 104 are fixedly connected to the cover 105. The inner bottom end of the protective box 103 is provided with a slope 106. The front bottom of the protective box 103 is rotatably connected to the first electric door 107, and the left bottom of the protective box 103 is rotatably connected to the second electric door 108. A robotic arm 109 for unloading molded products is also provided on the top left side of the machine body 1.

[0031] Those skilled in the art can understand that, the output end of the fourth drive motor 602 drives the drive wheel 603 to rotate, and under the drive of the belt 605, the driven wheel 604 and the fifth electric push rod 601 rotate as a whole, thereby realizing the rotation of the fixed frame 606, so that the fixed frame 606 can be maintained in a horizontal state or a vertical state, and when the fixed frame 606 is in a vertical state, the output end of the fourth stepper motor 609 drives the fourth screw rod 607 to rotate, so that the lifting member 610 moves up and down, driving the second scraper 611 connected to it to move up and down.

[0032] Example 6 Please refer to Figure 2 and Figure 3 As shown, the injection molding mechanism 2 includes a second electric push rod 201 fixedly mounted on the left side of the storage box 101, and a lifting frame 202 is fixedly mounted on the output end of the second electric push rod 201, and the lifting frame 202 is internally rotatably connected to the first screw rod 203, and a first guide rod 204 is also fixedly mounted in the lifting frame 202, and the outer surface of the first screw rod 203 is threadedly connected to a movable block 206, and the movable block 206 is threadedly connected to the first screw rod 203, and a first stepper motor 205 for driving the first screw rod 203 to rotate is provided on the outside of the lifting frame 202, and a conveying cylinder 207 is installed on the outside of the movable block 206, and the conveying cylinder 207 is internally rotatably connected to a spiral feeding rod 209, and the bottom left side of the conveying cylinder 207 is connected to a discharge pipe 210, and a valve 211 is provided on the discharge pipe 210, and the left end of the conveying cylinder 207 is provided with a first driving motor 208 for driving the spiral feeding rod 209 to rotate.

[0033] Those skilled in the art can understand that, by driving the first screw rod 203 to rotate through the output end of the first stepper motor 205, the movable block 206 reciprocates back and forth along the left side of the storage box 101, driving the conveying cylinder 207 to reciprocate back and forth, so that the conveying cylinder 207 can move to the top of each group of mold mechanisms 3 inside the protective box 103, and by controlling the rotation speed of the output end of the first drive motor 208, precise control of the spiral feeding rod 209 is achieved, thereby realizing automatic quantitative unloading, and through this rotating spiral conveying form, the molten raw material delivered into the conveying cylinder 207 by the feeding pump 102 will not solidify, thereby ensuring the good properties of the raw material; and by controlling the extension of the output end of the second electric push rod 201, the lifting frame 202 is driven to move downward, so that the conveying cylinder 207 moves downward, and the unloading pipe 210 extends into the shell 302 of the mold mechanism 3 to prevent the raw material from flowing outside the shell 302.

[0034] In order to clearly describe the working principle of the present invention, we use Figure 1 To illustrate the directional perspective, the directional perspective refers to "front, back, left, and right", as follows: S1. The storage box 101 stores molten plastic raw materials. The raw materials are transported to the inside of the conveying cylinder 207 by the feeding pump 102. Under the action of the injection molding mechanism 2, the raw materials are sequentially transported to the inside of the shell 302 of each group of mold mechanisms 3. By controlling the rotation speed of the output end of the first drive motor 208, the spiral feeding rod 209 is precisely controlled to achieve automatic quantitative unloading. Production is carried out synchronously through several groups of mold mechanisms 3, avoiding the time waiting for cooling and molding, and speeding up the efficiency of product production. S2. After the product is cooled and formed, the upper cover 304 is driven to open outward by controlling the rotation of the output end of the third drive motor 305, and the lower cover 306 is still located at the bottom of the shell 302 (as shown in FIG. Figure 12 In state A-1), since the upper cover 304 is rotated and opened, the top of the molded product is very likely to produce "uneven" particles due to "tearing". The output end of the fourth electric push rod 408 is extended to drive the first scraper 409 to move downward, so that the bottom of the first scraper 409 and the top of the molded product are located on the same horizontal plane. The second stepper motor 404 drives the second screw 402 to rotate again, so that the movable plate 405 reciprocates left and right, driving the first scraper 409 to reciprocate left and right to scrape the top of the molded product, remove the "uneven" particles on the top of the molded product, and make the top of the molded product smooth. The first scraper 409 is also used to scrape the top surface of the rotated upper cover 304, which is the side that contacts the product during injection molding, and also remove the "particles" adhered to the top to prevent the "particles" from affecting the next injection molding, thereby causing the product quality to be poor. S3. After the product is cooled and formed, due to the "adhesion" between the shell 302 and the product, it is easy to get stuck inside the shell 302 in the mold mechanism 3 and is not easy to fall off. Under the action of the output end of the third drive motor 305, the upper cover 304 is closed again, and the output end of the second drive motor 303 can drive the shell 302, the upper cover 304 and the lower cover 306 to flip and rotate as a whole. The rotation of the output end of the fourth drive motor 307 realizes the opening of the lower cover 306 to the outside (such as Figure 12 (A-2 state in the middle) At this time, the side originally located at the bottom of the product is turned over to face upward, and the above steps are repeated again to scrape off the "uneven" particles on the bottom of the product to make the bottom of the product smooth. The top surface of the rotated lower cover 306 is also scraped to remove the "particles" adhered to the top of the lower cover 306; S4, again by controlling the rotation of the output end of the third driving motor 305, the upper cover 304 is driven to open outward (such as Figure 12 302, and the top of the rotating member 507 is on the same horizontal plane as the top of the second clamping member 517 and the top of the first clamping member 512, so that the molded product falls on the top of the rotating member 507. S5. Then, the first threaded rod 510 is driven to rotate by the output end of the first servo motor 511, so that the two groups of first clamping members 512 are close to each other, so as to clamp and fix the front and back sides of the molded product, while the left and right sides of the molded product are not clamped by the two groups of second clamping members 517. Again, under the action of the output end of the third stepper motor 504, the clamped molded product is moved to the middle position inside the protective box. Under the action of the output end of the fifth drive motor 506, the rotating member 507 is rotated, driving the left and right sides of the molded product toward the second cleaning mechanism 6 in sequence. In the initial state, the fixed frame 606 is in a horizontal state. Under the action of the extension of the output end of the fifth electric push rod 601, the fixed frame 606 is driven to approach the product, and again through the fourth drive motor 60 2 drives the driving wheel 603 to rotate, and under the drive of the belt 605, the driven wheel 604 and the fifth electric push rod 601 rotate as a whole, realizing the rotation of the fixed frame 606, so that the fixed frame 606 is in a vertical state. The fixed frame 606 is located between the second clamping member 517 and the product. Under the action of the extension of the output end of the fifth electric push rod 601 again, the second scraper 611 contacts the product, and the output end of the fourth stepping motor 609 drives the fourth screw rod 607 to rotate, so that the lifting member 610 moves up and down, driving the second scraper 611 connected to it to move up and down, cleaning the left side of the product and removing the "uneven" particles thereon. Similarly, in this way, the "uneven" particles on the right side of the product are also removed. S6. The second threaded rod 515 is driven to rotate by the output end of the second servo motor 516, so that the two sets of second clamping members 517 approach each other, clamping and fixing the left and right sides of the cleaned product, while the two sets of first clamping members 512 move away from each other, releasing the clamping of the front and back sides of the product. The above steps are repeated again, and the front and back sides of the product are cleaned in turn by the second cleaning mechanism 6, thereby improving the product quality and meeting the needs of the staff. After cleaning, the auxiliary mechanism 5 drives the product to move to the second electric door 108, and the robot arm 109 can take it away. The whole process is automated, convenient and fast. S7. While cleaning the front, back, left and right sides of the product, the first scraper 409 extends into the shell 302 in the mold mechanism 3 and moves up and down to remove the "particles" adhered to the inner wall of the shell 302, thereby achieving comprehensive cleaning of the mold mechanism 3 without affecting the quality of the product during the next injection molding. The "particles" after cleaning and scraping are collected in the storage box 101 and used for the next melting and production of molten raw materials, avoiding waste of raw materials and meeting the needs of the staff.
