Description

Technical Field

[0001] The utility model relates to the field of injection molding, in particular to an anti-clogging plastic injection molding device. Background Art

[0002] In the plastics processing industry, injection molding is a widely used molding method. The performance of the injection molding device directly affects the production quality and efficiency of plastic products. The injection nozzle is an extremely critical component in the injection molding device, and its working state plays a decisive role in the entire injection molding process.

[0003] The injection nozzle structure of traditional injection molding devices is usually relatively closed. Once impurities enter the interior, cleaning is extremely difficult. As impurities continue to accumulate, it is very easy to cause the injection nozzle to become blocked, resulting in interruption of the injection molding process. This not only reduces production efficiency and increases production costs, but may also cause unstable injection pressure due to blockage, affecting the molding quality of plastic products and producing defective products. In addition, during the injection molding process, if the raw material temperature is not properly controlled, the plastic is likely to solidify inside it, which will also hinder the normal flow of the plastic and cause blockage, thereby affecting production. Therefore, it is necessary to design an anti-blocking plastic injection molding device to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide an anti-clogging plastic injection molding device to solve the problems raised by the above background technology.

[0009] Preferably, the limiting assembly includes a connecting plate, which is rotatably mounted on one side of the movable block. A U-shaped card is fixedly mounted on one side of the connecting plate, and the U-shaped card passes through the inner wall of the card slot.

[0010] Preferably, the width of the U-shaped card plate matches the width of the card slot.

[0011] Preferably, the cross section of the interference groove is triangular.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The anti-clogging plastic injection molding device injects molten plastic into the mold through a half-injection molding nozzle for injection molding. The half-injection molding nozzle is heated by a heating sleeve.

[0022] A card slot 6 is provided on the bottom surface of the L-shaped plug plate 4, a guide plate 7 is fixedly installed on the bottom surface of the mounting block 2, a movable block 8 is slidably installed on the outside of the guide plate 7, an adjustment component for driving the movable block 8 to rise and fall is installed on the surface of the mounting block 2, and a limit component passing through the card slot 6 is installed on one side of the movable block 8.

[0023] Specifically, the half injection nozzle 1 can be heated by the heating sleeve 3 to melt the solidified plastic therein. By removing the heating sleeve 3 , the two half injection nozzles 1 can be easily separated and the injection hole can be cleaned.

[0024] The heating sleeve 3 is appropriately matched with the two half injection nozzles 1 in size, and a heating wire is provided inside the heating sleeve 3. By energizing the heating wire inside the heating sleeve 3, the heating sleeve 3 can be heated, and the half injection nozzles 1 can be heated through the heating sleeve 3.

[0025] Wherein: the adjustment component includes a threaded rod 11, the threaded rod 11 is threadedly connected to the inside of the mounting block 2, the threaded rod 11 is rotatably mounted on the top surface of the movable block 8, and rotating the threaded rod 11 can drive the movable block 8 to slide along the outside of the guide plate 7.

[0026] Among them: the limiting assembly includes a connecting plate 9, which is rotatably mounted on one side of the movable block 8, and a U-shaped card plate 10 is fixedly mounted on one side of the connecting plate 9. The U-shaped card plate 10 passes through the inner wall of the card slot 6, and the width of the U-shaped card plate 10 matches the width of the card slot 6. After the U-shaped card plate 10 passes through the card slot 6, it pushes the L-shaped plug plate 4 upward, so that the L-shaped plug plate 4 can resist the inclined surface of the inner wall of the resistance groove 5, exerting a force on the two mounting blocks 2 to move closer to each other.

[0027] Working principle: The utility model is an anti-clogging plastic injection molding device. Plastic in a molten state is injected into a mold through a half-injection nozzle 1 for injection molding. The half-injection nozzle 1 is heated by a heating sleeve 3. When there is solidified plastic in the half-injection nozzle 1, the solidified plastic can be quickly melted, thereby ensuring the smoothness of the injection molding of the half-injection nozzle 1 and preventing the solidified plastic from being blocked inside the half-injection nozzle 1, affecting the injection molding efficiency.

[0028] When the half injection nozzle 1 is clogged with too many impurities, the threaded rod 11 is rotated to drive the movable block 8 to move downward, thereby driving the U-shaped clamping plate 10 to move downward through the connecting plate 9, so that the U-shaped clamping plate 10 is disengaged from the clamping slot 6, and then the connecting plate 9 is rotated to drive the U-shaped clamping plate 10 to move to a position where it does not block the L-shaped plug-in plate 4 in the vertical direction, and then the L-shaped plug-in plate 4 and the heating sleeve 3 are controlled to move downward, so that the heating sleeve 3 is disengaged from the half injection nozzle 1. At this time, the two half injection nozzles 1 can be separated, which is convenient for comprehensive cleaning of the injection holes in the half injection nozzle 1. The cleaning and maintenance are relatively convenient, and impurities are effectively prevented from clogging the half injection nozzle 1;

[0029] After cleaning, the two half injection molding nozzles 1 are put together, and the heating sleeve 3 is set on the outside of the half injection molding nozzle 1 to limit the half injection molding nozzle 1. Thereafter, the heating sleeve 3 is moved upward to drive the L-shaped plug plate 4 into the inside of the interference groove 5, and then the connecting plate 9 and the U-shaped card plate 10 are grabbed so that the U-shaped card plate 10 moves to the position facing the card groove 6. The threaded rod 11 is rotated to drive the movable block 8, the connecting plate 9, and the U-shaped card plate 10 to move upward, so that the U-shaped card plate 10 pushes the L-shaped plug plate 4 to move upward until the L-shaped plug plate 4 is against the inner wall inclined surface of the interference groove 5. The L-shaped plug plate 4 exerts a horizontal force on the mounting block 2 by interfering with the interference groove 5, so that the two mounting blocks 2 have the force to push the two half injection molding nozzles 1 together, thereby ensuring the airtightness of the connection between the two half injection molding nozzles 1.
