A pair of sliding grooves 14 are provided; a scraper assembly is provided at the top of the plate 2; the scraper assembly is used to clean the injection head 8. During operation, the plate 2 is fixed to the top of the base 1 by setting the base 1, and the top of the plate 2 is fixed to the top plate 4 by a set of support rods 3. After the operator places the lower mold 10 in the first groove 9, the lower mold 10 can be fixed by a set of clamping plates 12. Then, the injection head 8 is driven by the cylinder telescopic rod 5 to perform injection molding in the upper mold 11 and the lower mold 10. After the injection is completed, the cylinder drives the injection head 8 back to its original position, and the scraper assembly can be used to scrape the injection head 8 to avoid clogging of the injection head 8 during the next injection, which would cause damage to the equipment.

[0024] The scraping assembly includes sliders 15 and a transmission unit; a pair of sliders 15 are slidably connected in a pair of grooves 14; a connecting plate 16 is fixedly connected to one side of the pair of sliders 15; a first scraper 17 is fixedly connected to the top of the connecting plate 16; a collection frame 18 is slidably connected to the first scraper 17. During operation, by causing the pair of sliders 15 to slide in the grooves 14, when the transmission unit moves the pair of sliders 15 to one side, the first scraper 17 on the connecting plate 16 can scrape the injection head 8. The residual glue on the injection head 8 is scraped off to prevent clogging and equipment damage during the next injection. After the pair of sliders 15 move to the other end of the slide 14, the operator can stop the first motor 19, wait for the plastic inside the mold to dry and remove it, and then inject the glue again. After that, the operator can turn on the first motor 19 to make the scraper return. Since the first scraper 17 can scrape glue from both sides, the other side can scrape the injection head 8 during the return stroke. The collection frame 18 can collect the glue from both sides of the first scraper 17.

[0025] The transmission unit includes a first motor 19; the first motor 19 is fixedly connected to one side of the plate 2; the output end of the first motor 19 is provided with a first threaded rod 20; one end of the first threaded rod 20 passes through the plate 2; a second threaded rod 21 is rotatably connected to one side of the plate 2; one end of the second threaded rod 21 passes through the plate 2 and is rotatably connected to one side of the slide groove 14; a pair of sliders 15 are respectively threadedly connected to the first threaded rod 20 and the second threaded rod 21; a first synchronous pulley 22 is fixedly connected to the first threaded rod 20; a second synchronous pulley 23 is fixedly connected to the second threaded rod 21; the first synchronous pulley 22 and the second synchronous pulley 23 are connected by a synchronous belt 24. During operation, by fixing the first motor 19 to one side of the plate 2, when the first motor 19 drives the first threaded rod 20 to rotate, the first threaded rod 20 will drive the second rotating rod to rotate through the synchronous belt 24, so that the sliders 15 move forward simultaneously in the slide groove 14, thereby driving the first scraper 17 to scrape the glue on the injection head 8.

[0026] A square box 25 is fixedly connected inside the base 1; a set of through slots 26 are opened at the top of the square box 25; the set of through slots 26 extends upward through the flat plate 2; a set of clamping plates 12 are slidably connected in the set of through slots 26; a power component is provided inside the base 1; the power component is used to drive the movement of the clamping plates 12. During operation, the square box 25 is set inside the base 1, and the power component is set inside the square box 25. Since the lower mold 10 is fixed by a set of clamping plates 12, when the operator needs to replace the lower mold 10, the power component can drive the set of clamping plates 12 to move simultaneously, so that the pair of clamping plates 12 no longer clamp and fix the lower mold 10. The operator can take away the lower mold 10 to be replaced and place the required lower mold 10 inside the first groove 9. Then, the set of clamping plates 12 clamps the lower mold 10 from all sides simultaneously. In this way, the replacement of the entire set of molds can be completed very easily.

[0027] The power component includes a second motor 27; the second motor 27 is fixedly connected to the bottom end of the square box 25; the output end of the second motor 27 is provided with a first rotating rod 28; one end of the first rotating rod 28 passes through the square box 25 and is rotatably connected inside the square box 25, and is fixedly connected to a first bevel gear 29; a set of second bevel gears 30 is rotatably connected inside the square box 25; one end of each set of second bevel gears 30 is fixedly connected to a third threaded rod 31; one end of each third threaded rod 31 is rotatably connected to the inner side wall of the square box 25; a set of clamping plates 12 are threadedly connected to the third threaded rods 31; the set of second bevel gears 30 meshes with the first bevel gears 29. During operation, by fixing the second motor 27 to the bottom end of the square box 25, when the operator starts the second motor 27, the first rotating rod 28 will drive the first bevel gear 29 to rotate, causing the set of second bevel gears 30 to drive the clamping plates 12 to move, which can clamp or release the clamping of the lower mold 10, making it convenient for the operator to change the mold.

[0028] A toothed plate 32 is fixedly connected to the top of the plate 2; a sleeve 34 is rotatably connected to one side of one of the pair of sliders 15, and one end of the sleeve 34 passes through the slider 15; a threaded shaft 33 is internally threaded to the sleeve 34; one end of the threaded shaft 33 is rotatably connected to one side of the collection frame 18; a first gear 35 is fixedly connected to one end of the sleeve 34; the first gear 35 meshes with the toothed plate 32. During operation, by fixing the toothed plates 32 to the top of the plate 2, when the first motor 19 drives the pair of sliders 15 to move to one side, the first scraper 17 will... When the first scraper 17 removes the residual glue from the injection head 8, the glue will adhere to the scraped area and may affect the next scraping operation. Therefore, when the first motor 19 drives the slider 15 to return, the first gear 35 will mesh with the toothed plate 32, causing the collection frame 18 to move on the first connecting plate 16 and scrape the scraped area of ​​the first scraper 17 to collect the injection glue. In this way, the first scraper 17 can still scrape the injection head 8 in the next scraping operation.

[0029] Working principle: A base 1 is set up, and a plate 2 is fixed to the top of the base 1. A set of support rods 3 then fixes the top plate 4 to the top of the plate 2. After the operator places the lower mold 10 into the first groove 9, a set of clamping plates 12 can be used to fix the lower mold 10. Then, the cylinder extension rod 5 drives the injection head 8 to perform injection molding into the upper mold 11 and the lower mold 10. After injection molding is complete, the cylinder drives the injection head 8 back to its original position. The glue scraper assembly can then scrape the glue from the injection head 8 to prevent clogging and damage to the equipment during the next injection. A pair of sliders 15 slide within a pair of grooves 14. When the transmission unit moves the pair of sliders 15 to one side, the first scraper on the connecting plate 16... Plate 17 can scrape the injection head 8 to remove residual glue, preventing clogging and equipment damage during the next injection. After the pair of sliders 15 move to the other end of the groove 14, the operator can stop the first motor 19, wait for the plastic inside the mold to dry and be removed, and then restart the first motor 19 to return the scraper. Since both sides of the first scraper 17 can scrape, the other side scrapes the injection head 8 during the return stroke. The collection frame 18 collects the glue from both sides of the first scraper 17. By fixing the first motor 19 to one side of the plate 2, when the first motor 19 drives the first threaded rod 20 to rotate, the first threaded rod 20 is driven by the synchronous belt 24. The second rotating rod rotates, causing the slider 15 to move forward simultaneously within the groove 14, thereby driving the first scraper 17 to scrape the glue off the injection head 8. A square box 25 is installed inside the base 1, and a power component is installed inside the square box 25. Because the lower mold 10 is fixed by a set of clamping plates 12, when the operator needs to replace the lower mold 10, the power component can drive the set of clamping plates 12 to move simultaneously, so that the clamping plates 12 are no longer clamping and fixing the lower mold 10. The operator can then remove the lower mold 10 to be replaced and place it inside the first groove 9. Then, the set of clamping plates 12 will simultaneously clamp the lower mold 10 from all sides, thus easily completing the replacement of the entire mold. For mold replacement, a second motor 27 is fixed to the bottom of the square box 25. When the operator starts the second motor 27, the first rotating rod 28 drives the first bevel gear 29 to rotate, causing a set of second bevel gears 30 to move the clamping plate 12. This allows for clamping or unclamping of the lower mold 10, facilitating mold replacement. A toothed plate 32 is fixed to the top of the plate 2. When the first motor 19 drives a pair of sliders 15 to move to one side, the first scraper 17 scrapes the glue off the injection head 8. After the first scraper 17 removes the residual glue from the injection head 8, the glue may adhere to the scraped area, potentially affecting the next scraping operation. Therefore, when the first motor 19 drives the sliders 15 back, [the scraper 17 is used to remove the glue].The first gear 35 meshes with the toothed plate 32, causing the collecting frame 18 to move on the first connecting plate 16. This scrapes the scraping area of ​​the first scraper 17, collecting the injection molding compound. Thus, the first scraper 17 can continue to scrape the injection head 8 in the next scraping operation.
