All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figures 1-15The present invention provides a water-cooled plastic product forming mold and a forming method technical solution: the water-cooled plastic product forming mold includes: an upper mold 1 and a lower mold 2, the outer wall of the top of the lower mold 2 is in active contact with the outer wall of the bottom of the upper mold 1, the outer wall of the top of the lower mold 2 is provided with a placement groove, the middle position of the top outer wall of the upper mold 1 is provided with an injection port 11, the interior of the lower mold 2 is movably plugged with a mold core 3, a water tank 5 is provided at the bottom of the interior of the lower mold 2, a filter box 41 is fixedly connected to one side of the water tank 5, equipment grooves 32 are provided on both sides of the top of the mold core 3, and a limiting groove 36 is provided at a position aligned with the equipment groove 32 in the interior of the lower mold 2.

[0042] By pulling the handle 33 upward, the core 3 can be driven out of the lower mold 2, thereby replacing the core 3. Since the same set of molds can adapt to cores 3 of various shapes, the overall cost of the mold can be reduced, and products of various shapes can be produced within the same set of mold frames, thereby meeting the diverse needs of the market.

[0043] Example 2

[0044] On the basis of embodiment one, a slide groove 2 62 is provided on the opposite side of the two handles 1 33, and a through hole 63 with the outer walls on both sides connected is provided on the handle 1 33. The outer wall on one side of the through hole 63 is connected through the outer wall of one end of the slide groove 2 62. The outer wall on one side of the slide groove 2 62 is fixedly connected with an elastic block 61 near the position of the through hole 63. The interior of the slide groove 2 62 is slidably connected with a support rod 6. The outer wall of one end of the elastic block 61 is movably contacted with the outer wall on one side of the support rod 6, and the outer wall of the support rod 6 is movably plugged into the interior of the through hole 63.

[0045] By setting the elastic block 61, the stability of the support rod 6 inside the slide groove 2 62 can be increased. At this time, the handle 1 33 is changed into a positioning rod. Through the cooperation of the handle 1 33 and the positioning groove 31, it can ensure that the upper mold 1 and the lower mold 2 are quickly and accurately docked when closed, avoiding misalignment or offset between the molds, and correspondingly reducing the time for mold adjustment, making the production process smoother, thereby improving the overall production efficiency.

[0046] Example 3

[0047] On the basis of the second embodiment, a cooling pump 53 is provided inside the water tank 5, and the output end of the cooling pump 53 is fixedly connected to a square tube 54, and the outer wall of one side of the square tube 54 is fixedly connected to a water outlet pipe 55. A water cooling tank 51 is provided inside the lower mold 2 near the outer side of the mold core 3, and the outer wall of the water outlet pipe 55 is connected to the inside of the water cooling tank 51. A plurality of partitions 52 are fixedly connected to the inside of the water cooling tank 51, and a water outlet 56 is provided at the bottom of the water cooling tank 51. A plurality of outflow holes 521 are provided below the plurality of partitions 52, and the outflow One side of the inside of the hole 521 is fixedly connected to the mounting plate 1 522, and the other side of the inside of the outflow hole 521 is fixedly connected to the mounting plate 2 524. The inside of the mounting plate 2 524 is slidably connected to the T-shaped rod 526. The outer wall of one side of the mounting plate 2 524 is fixedly connected to the return spring 525. The outer wall of one end of the two return springs 525 is fixedly connected to the outer wall of one side of the mounting plate 1 522. The outer wall of one end of the T-shaped rod 526 is fixedly connected to the baffle 523. The outer wall of the baffle 523 is in movable contact with the inside of the outflow hole 521.

[0048] The water-cooling tank 51 is divided into a plurality of small compartments by the partition 52 inside the water-cooling tank 51, and the height of the small compartments is the same as the height of the mold core 3. In this way, after the cold water fills the plurality of small compartments, the surface of the mold core 3 can be evenly cooled, thereby avoiding uneven cooling of different parts of the plastic product during molding, which affects the appearance quality of the product. Accordingly, since the water-cooling tank 51 is the same height as the mold core 3, the entire outer wall of the mold core 3 can fully exchange heat with the cold water in the water-cooling tank 51, thereby ensuring that the product inside the mold core 3 is evenly cooled.

[0049] Example 4

[0050] On the basis of Example 3, an equipment box is fixedly connected to the upper part of the interior of the square tube 54, and an electric telescopic rod 8 is fixedly connected to the upper part of the interior of the equipment box. The output end of the electric telescopic rod 8 passes through the bottom of the equipment box and is fixedly connected to a mounting block 81. The outer walls on both sides of the mounting block 81 are fixedly connected to a second blocking block 82. The upper and lower sides of the mounting block 81 are provided with a card slot 83. The inner wall of the square tube 54 is fixedly connected to a plurality of limit blocks 84, and the outer wall of the limit block 84 is in movable contact with the inside of the card slot 83.

[0051] The mounting block 81 drives the second blocking block 82 to be inserted into the interior of the cleaning pipe 7. When it is necessary to work on the outlet pipe 55 and the cleaning pipe 7 at the same time, the mounting block 81 can drive the second blocking block 82 to stagnate between the cleaning pipe 7 and the outlet pipe 55, thereby increasing the flexibility of the water flow accordingly, so as to control the direction of the water flow. Then, through the cooperation of the limit block 84 and the slot 83, the mounting block 81 can drive the second blocking block 82 to find the position of the cleaning pipe 7 and the outlet pipe 55 more accurately.

[0052] Example 5

[0053] On the basis of Example 4, the outer wall of the other side of the square tube 54 is fixedly connected to the cleaning tube 7, the outer wall of one end of the cleaning tube 7 is fixedly connected to the bellows 71, the outer wall of the bellows 71 is slidably connected to the inside of the placement groove, the outer wall of one end of the bellows 71 is fixedly connected to the spray gun 72, the inside of the placement groove is fixedly connected to the placement rod, and the outer wall of the top of the placement rod is in movable contact with the outer wall of the bottom of one side of the spray gun 72.

[0054] The operator uses the spray gun 72 to flush the inside of the mold core 3, and then the bellows 71 can be extended and retracted, making it convenient for the operator to adjust the length of the spray gun 72, thereby increasing the cleaning effect on the inside of the mold core 3 and avoiding residual impurities affecting the next plastic product molding. Correspondingly, the appearance of the plastic product is increased and the defects of the plastic product are reduced.

[0055] Example 6

[0056] On the basis of Example 5, a blocking block 48 is movably inserted at the lower part of the interior of the mold core 3, and a connecting rod is fixedly connected to one side of the blocking block 48. A one-way valve 42 is fixedly connected to the lower part of the interior of the filter box 41, and a slide groove 44 is provided on both sides of the interior of the filter box 41. The interior of the filter box 41 is slidably connected to a filter plate 43, and both sides of the filter plate 43 are fixedly connected to sliders 47. The outer wall of the slider 47 is slidably connected to the interior of the slide groove 44, and the outer wall of the bottom of the slider 47 is fixedly connected to a support spring 45. The filter box 41 is provided with a discharge port 46 with the outer walls on both sides connected to each other, and the outer wall on one side of the discharge port 46 is movably in contact with the collection box 4, and the outer wall of the collection box 4 is in movably contact with the interior of the lower mold 2.

[0057] The sewage can be filtered through the filter plate 43 provided inside the filter box 41, and the filtered water is discharged into the water tank 5 through the one-way valve 42, and the water used to clean the mold core 3 is reused, which is beneficial to saving water resources.

[0058] In actual use, when replacing the mold core 3 according to the plastic product, first, the operator moves the support rod 6 to the inside of the through hole 63. At this time, the two handles 33 are pushed forward, and then through the movement of handle 1 33, the pull rod can drive the U-shaped limit rod 35 to move on the slide rod 34, so that the U-shaped limit rod 35 leaves the inside of the limit groove 36, and the limit on the mold core 3 can be released. At this time, pull the handle 1 33 upward to drive the mold core 3 out of the inside of the lower mold 2, thereby replacing the mold core 3. Since the same set of molds can adapt to mold cores 3 of various shapes, the overall cost of the mold can be reduced, and products of various shapes can be produced within the same set of mold frames, thereby meeting the diverse needs of the market.

[0059] When the mold core 3 is replaced, the support rod 6 can be processed and moved to the inside of the second slide groove 62. Then, by setting the elastic block 61, the stability of the support rod 6 inside the second slide groove 62 can be increased. At this time, the handle 1 33 is changed into a positioning rod. Through the cooperation of the handle 1 33 and the positioning groove 31, it can ensure that the upper mold 1 and the lower mold 2 are quickly and accurately docked when closed, avoiding misalignment or offset between the molds, and correspondingly reducing the time for mold adjustment, making the production process smoother, thereby improving the overall production efficiency.

[0060] The plastic raw material is injected into the interior of the mold core 3 through the injection port 11. At this time, the refrigeration pump 53 is started to work. Then, through the operation of the refrigeration pump 53, the cold water inside the water tank 5 can enter the interior of the square tube 54 through the input end of the refrigeration pump 53, and finally flow into the interior of the water-cooling tank 51 through the outlet pipe 55. The water-cooling tank 51 is then divided into a plurality of small cells by the partition 52 inside the water-cooling tank 51, and the height of the small cells is the same as the height of the mold core 3. In this way, after the cold water fills the plurality of small cells, the surface of the mold core 3 can be evenly cooled, thereby avoiding uneven cooling of different parts of the plastic product during molding, affecting the appearance quality of the product. Accordingly, because the water-cooling tank 51 is the same height as the mold core 3, the entire outer wall of the mold core 3 can fully exchange heat with the cold water in the water-cooling tank 51, thereby ensuring that the product inside the mold core 3 is evenly cooled.

[0061] The water cooling tank 51 is then divided into multiple small grids by a partition 52, so that the water level inside the water cooling tank 51 can be controlled to be the same as the height of the mold core 3, and the water level of each small grid can be the same as the height of the mold core 3, so that the outer wall of the mold core 3 can be in contact with the cold water more comprehensively. This comprehensive heat exchange can significantly improve the cooling efficiency and enable the product inside the mold core 3 to reach the required cooling temperature more quickly.

[0062] When the first cell is filled with water, the water pressure inside the cell increases. At this time, the water pressure can push the baffle 523 to move, so that the baffle 523 leaves the outflow hole 521, allowing cold water to enter the next cell. After the cold water enters the last cell, the water that has taken away the heat can enter the inside of the water tank 5 through the water outlet 56 for recycling. The T-shaped rod 526 can be set to guide the baffle 523 when it is driven by the return spring 525 to return to its original position, thereby increasing the efficiency of the baffle 523 returning to its original position.

[0063] It should be noted that the force of the return spring 525 itself is smaller than the pressure when the small cell is filled with water.

[0064] After the plastic product is formed and taken out, if you want to clean the inside of the mold core 3, you can start the electric telescopic rod 8, and then through the operation of the electric telescopic rod 8, the mounting block 81 can drive the blocking block 2 82 to be inserted into the inside of the water outlet pipe 55, thereby blocking the water outlet pipe 55 to prevent cold water from entering the inside of the water cooling tank 51 when cleaning the inside of the mold core 3. At this time, the operator pulls the connecting rod, and then through the movement of the connecting rod, the blocking block 1 48 can be driven to leave the inside of the sewage outlet, and then the spray gun 72 is taken out from the inside of the placement tank, the refrigeration pump 53 can be started to provide water to the inside of the square tube 54, so that the operator can use the spray gun 72 to flush the inside of the mold core 3. The bellows 71 can be extended and retracted, which is convenient for the operator to adjust the length of the spray gun 72, thereby increasing the cleaning effect of the inside of the mold core 3 and avoiding the residual impurities from affecting the next plastic product molding, correspondingly increasing the beauty of the appearance of the plastic product and reducing the defects of the plastic product.

[0065] It should be noted that the spray gun 72 and the bellows 71 are prior art.

[0066] When water is not needed to enter the interior of the cleaning pipe 7, the mounting block 81 can be used to drive the blocking block 2 82 to be inserted into the interior of the cleaning pipe 7. When the outlet pipe 55 and the cleaning pipe 7 need to be worked on at the same time, the mounting block 81 can be used to drive the blocking block 2 82 to stagnate between the cleaning pipe 7 and the outlet pipe 55, thereby correspondingly increasing the flexibility of the water flow so as to control the direction of the water flow. The limiting block 84 and the card slot 83 can then be used to cooperate so that the mounting block 81 can drive the blocking block 2 82 to find the positions of the cleaning pipe 7 and the outlet pipe 55 more accurately.

[0067] The filter plate 43 is then moved up and down, and the particles intercepted by the filter plate 43 enter the collection box 4 through the discharge port 46, which is convenient for collecting the particles. By pulling through the handle 2 on one side of the collection box 4, the collection box 4 can be taken out from the interior of the lower mold 2 to remove the particles inside the collection box 4.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
