At the bottom ends of the connecting seats, a movable plate is installed, and the movable plate is movably arranged on the outer side wall of the guide rod. At the bottom end of the movable plate, an upper injection mold is installed. At the top end inside the upper injection mold, a material injection pipe is arranged. On the top of the placement seat, a lower injection mold is installed, and at the front end of the lower injection mold, a storage seat is installed. Inside the storage seat, a storage groove is arranged. At the front end of the storage seat, a high-pressure pump is installed. On the right side of the high-pressure pump, a high-pressure water pipe is installed, and at the rear end of the high-pressure water pipe, a spray pipe is installed. At the rear end of the spray pipe, a nozzle is installed. On the left side of the high-pressure pump, a water inlet is arranged. On both sides of the top of the spray pipe, connecting rods are fixed, and the top ends of the connecting rods are fixed to the bottom end of the movable plate.
[0006] Preferably, there are two sets of the connecting rods, and the two sets of connecting rods are symmetrically distributed about the central axis of the spray pipe.
[0007] Preferably, there are several nozzles, and several nozzles are inclined at one end of the spray pipe.
[0008] Preferably, an inner cylinder is movably arranged inside the material injection pipe. Fixed blocks are fixed on both sides of the material injection pipe. Clamping rings are hingedly installed on the outer side walls of the fixed blocks through shafts. Inner seats are movably arranged inside the clamping rings, and one side of each inner seat is fixed to one side of the material injection pipe. Card slots are arranged inside each inner seat.
[0009] Preferably, the cross-section of the inner cylinder is smaller than that of the material injection pipe, and a clamping structure is formed between the inner cylinder and the material injection pipe.
[0010] Preferably, two groups of clamping rings are provided, and a clamping structure is formed between the two groups of clamping rings and the inner seats through the card slots.
[0011] Preferably, a metal sealing strip is fixed at the edge of the bottom end of the upper injection mold, and a magnetic sealing groove is arranged at the edge of the top end inside the lower injection mold.
[0012] Preferably, the sizes of the metal sealing strip and the magnetic sealing groove are adapted to each other, and a clamping structure is formed between the metal sealing strip and the magnetic sealing groove.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The wiper link injection mold with a pulsed waterway cleaning mechanism not only realizes the pulsed cleaning of the inside of the lower injection mold, realizes the sealing of the fit between the upper injection mold and the lower injection mold to prevent material overflow, but also realizes the convenient cleaning and maintenance of the material injection pipe;
[0014] (1) By providing components such as a high-pressure water pipe, a high-pressure pump, a connecting rod, and a nozzle, when the movable plate pulls the upper injection mold upward, the movable plate will also pull the spray pipe upward through the connecting rod, moving above the lower injection mold. Then, the nozzles evenly distributed at one end of the spray pipe can spray water into the inside of the lower injection mold to perform pulsed cleaning on the inner side wall of the lower injection mold, thereby realizing the convenient cleaning of the lower injection mold by this injection mold and making it more convenient to use;
[0015] (2) By providing a metal sealing strip and a magnetic sealing groove, during the use of this injection mold, the upper injection mold and the lower injection mold will fit together to form a complete injection mold for the production of wiper links. When the upper injection mold and the lower injection mold fit together, the metal sealing strip will be magnetically adsorbed into the magnetic sealing groove, forming a corresponding seal between the upper injection mold and the lower injection mold, thereby ensuring the sealing performance of the fit between the upper injection mold and the lower injection mold and preventing the material injected into the injection mold from overflowing.
[0016] (3) By setting components such as an inner cylinder, a fixing block, a clamping seat, and a snap ring, during the use of this injection mold, materials are injected into the interior of the injection mold through a feed pipe. However, as the number of injection times increases, a certain amount of materials will adhere to the inner side wall of the feed pipe, causing blockage of the feed pipe and making it difficult to clean. Since the above components are added, the feed pipe can be disassembled and maintained, thus facilitating the cleaning of the feed pipe to avoid blockage and ensuring the smoothness of feeding.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1: Please refer to Figures 1-4, A wiper link injection mold with a pulsed waterway cleaning mechanism, including a placement seat 1. On both sides of the top of the placement seat 1, guide rods 2 are installed. At the top of the guide rods 2, a top plate 4 is installed. On both sides of the bottom of the top plate 4, telescopic cylinders 5 are installed. At the bottom of the telescopic cylinders 5, connection seats 8 are installed. At the bottom of the connection seats 8, a movable plate 3 is installed, and the movable plate 3 is movably arranged on the outer side wall of the guide rod 2. At the bottom of the movable plate 3, an injection upper mold 9 is installed. At the top of the inside of the injection upper mold 9, a material injection pipe 7 is arranged. On the top of the placement seat 1, an injection lower mold 12 is installed, and at the front of the injection lower mold 12, a storage seat 17 is installed. Inside the storage seat 17, a storage groove 18 is arranged. At the front of the storage seat 17, a high-pressure pump 14 is installed. On the right side of the high-pressure pump 14, a high-pressure water pipe 13 is installed, and at the rear end of the high-pressure water pipe 13, a spray pipe 19 is installed. At the rear end of the spray pipe 19, a nozzle 20 is installed. On the left side of the high-pressure pump 14, a water inlet 15 is arranged. On both sides of the top of the spray pipe 19, connecting rods 16 are fixed, and the top ends of the connecting rods 16 are fixed to the bottom of the movable plate 3. There are two groups of connecting rods 16, and the two groups of connecting rods 16 are symmetrically distributed about the central axis of the spray pipe 19, which can drive the spray pipe 19 to move up and down stably. A number of nozzles 20 are arranged, and a number of nozzles 20 are inclined at one end of the spray pipe 19. The number of nozzles 20 for pulsed cleaning of the injection upper mold 9 is more comprehensive, and the inclined nozzles 20 are more accurate in cleaning the injection upper mold 9;
[0024] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the water inlet 15 is connected to an external water pipe and a water tank. When the movable plate 3 pulls the injection upper mold 9 upward to return to its original position, the movable plate 3 will pull the spray pipe 19 out of the inside of the storage seat 17 and move above the injection lower mold 12 through the connecting rod 16. Then, the top plate 4 is started to spray external water into the inside of the injection lower mold 12 through the spray pipe 19 and the nozzle 20 to wash the inner side wall of the injection lower mold 12.
[0025] Embodiment 2: An inner cylinder 6 is movably arranged inside the material injection pipe 7. On both sides of the material injection pipe 7, fixing blocks 21 are fixed. On the outer side walls of the fixing blocks 21, clamping rings 24 are hingedly installed through shaft bodies 22. Inside the clamping rings 24, clamping seats 23 are movably arranged, and one side of each clamping seat 23 is fixed to one side of the material injection pipe 7. Inside the clamping seats 23, clamping grooves 25 are arranged. The cross-section of the inner cylinder 6 is smaller than that of the material injection pipe 7. A clamping structure is formed between the inner cylinder 6 and the material injection pipe 7, so that the inner cylinder 6 is stably installed inside the material injection pipe 7. There are two groups of clamping rings 24, and the two groups of clamping rings 24 form a clamping structure with the clamping seats 23 through the clamping grooves 25, so that the inner cylinder 6 can be stably installed inside the material injection pipe 7, and the inner cylinder 6 will not rotate inside the material injection pipe 7;
[0026] Specifically, asFigure 1 As shown in the figure, when the upper injection mold 9 is attached above the lower injection mold 12, the metal sealing strip 10 at the bottom end of the upper injection mold 9 will be engaged into the magnetic sealing groove 11 inside the lower injection mold 12, and the metal sealing strip 10 and the lower injection mold 12 are stably adsorbed together by magnetic force, so as to seal the fitting of the metal sealing strip 10 and the lower injection mold 12.
[0027] Embodiment 3: A metal sealing strip 10 is fixed at the edge of the bottom end of the upper injection mold 9, and a magnetic sealing groove 11 is arranged at the edge of the top end inside the lower injection mold 12. The sizes of the metal sealing strip 10 and the magnetic sealing groove 11 are adapted to each other, and a clamping structure is formed between the metal sealing strip 10 and the magnetic sealing groove 11, so that the sealing effect of the upper injection mold 9 and the lower injection mold 12 is better;
[0028] Specifically, as Figure 1 and Figure 4 shown in the figure, when the injection pipe 7 needs to be maintained, the snap ring 24 is flipped in sequence to disengage it from the clamping groove 25 inside the clamping seat 23, and then the inner cylinder 6 is pulled upward to move it out of the injection pipe 7, so as to facilitate the cleaning of the inner cylinder 6. After the inner cylinder 6 is cleaned, it is reinstalled into the injection pipe 7, and then the snap ring 24 is flipped in the reverse direction to engage it into the clamping groove 25 inside the clamping seat 23, so as to install the inner cylinder 6 inside the injection pipe 7 well, and keep the material injection of the injection pipe 7 unobstructed.
[0029] Working principle: When the present utility model is in use, the telescopic cylinder 5 is started, and the upper injection mold 9 is pushed downward to move and fit above the lower injection mold 12 through the sliding of the movable plate 3 on the outer side wall of the guide rod 2. When the upper injection mold 9 fits above the lower injection mold 12, the metal sealing strip 10 will be engaged into the inside of the magnetic sealing groove 11 to form a seal between the upper injection mold 9 and the lower injection mold 12. Then, the corresponding material is injected into the injection mold through the injection pipe 7 and waits for it to cool and form. After that, the upper injection mold 9 is pulled upward to open the mold. After the formed wiper link is taken out, when the movable plate 3 moves upward, the movable plate 3 will pull the spray pipe 19 to move above the lower injection mold 12 through the connecting rod 16. After the material is taken out, the top plate 4 can be started to spray the water outside through the spray pipe 19 and the nozzle 20 into the lower injection mold 12 to wash the inner side wall of the lower injection mold 12. After washing it clean, wipe it clean and continue the subsequent production.
