Technical Field

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

[0002] The injection molding cooling device is a key component in the injection molding process. It is used to control and manage the temperature in the injection mold to ensure that the plastic can be properly cooled and solidified during the molding process, thereby obtaining good molding quality.

[0003] The existing injection molding method is to add the raw materials to be injected into the injection mold gate, and extrude the raw materials by moving the upper mold downward, thereby achieving the extrusion of the raw materials, and finally obtaining the injection molded object.

[0004] When adding raw materials to the injection mold, frequently adding raw materials to the gate of the injection mold will cause the gate of the injection mold to be heated by the high temperature of the raw materials for a long time, resulting in a high temperature at the gate of the injection mold, which is inconvenient to achieve the purpose of heat dissipation and easily shortens the service life of the injection mold.

[0027] In this embodiment, locking blocks 10 are provided on both sides of the inner wall of the bottom end of the bracket 1, and the internal thread of the locking block 10 is provided with a screw rod 11, one end of the screw rod 11 is rotatably connected to a limiting block 12, and baffles are installed at the front and rear ends of the locking block 10, and the limiting block 12 is located between the two sets of baffles.

[0028] The locking block 10 is used to set the screw rod 11, the screw rod 11 is used to adjust the position of the limit block 12, and the two sets of baffles limit the movable limit block 12.

[0029] In this embodiment, a hidden hole 9 is opened at the upper end of the circular plate on the outer wall of the baffle tube 7 , and the upper end of the screw 8 is located inside the hidden hole 9 .

[0030] The hidden hole 9 facilitates the hidden installation of the screw 8 .

[0031] In this embodiment, a guide rod 13 is fixedly provided at one end of the limiting block 12 , and one end of the guide rod 13 is located inside the locking block 10 to slide.

[0032] The guide rod 13 performs secondary limiting on the limiting block 12 , thereby enhancing the stabilizing effect of the movement of the limiting block 12 and achieving better fastening of the injection mold 4 .

[0033] In this embodiment, four clamping blocks 16 are fixedly disposed on the inner wall of the bottom end of the bracket 1 , and four corresponding clamping grooves 15 are opened at the lower end of the injection mold 4 .

[0034] The clamping block 16 cooperates with the clamping slot 15 to achieve a stable placement of the injection mold 4 and to accurately limit the position of the injection mold 4 .

[0035] In this embodiment, a handle 14 is fixedly provided at one end of the screw rod 11 .

[0036] The handle 14 allows the operator to easily rotate the screw rod 11 , thereby making it easier to adjust the position of the limit block 12 .

[0037] In this embodiment, the shapes of the card slot 15 and the card block 16 are both rectangular. Four guide posts 17 are fixedly provided on the inner wall of the upper end of the bracket 1. The lower ends of the guide posts 17 pass through the upper mold 3 and slide inside the upper mold 3.

[0039] It should be noted that the utility model is an injection molding cooling device. When in use, the injection molding raw material tube is inserted into the interior of the baffle tube 7, and the raw material enters the lower end of the injection molding gate hole 5 through the baffle tube 7 to realize injection molding. After the injection molding is completed, the cylinder 2 is started to move the upper mold 3 downward, so that the upper mold 3 is located on the outer wall of the guide column 17 and is firmly pressed down. After being pressed down to the injection mold 4, the raw material inside the injection mold 4 is deformed to realize injection molding.

[0040] During the filling process, the raw material with a higher temperature will not contact the inner wall of the injection gate hole 5 for a long time, and will be blocked by the blocking tube 7 to reduce the transfer of heat and realize the cooling of the injection mold 4;

[0041] When the injection mold 4 needs to be removed, the handle 14 is rotated so that the handle 14 drives the screw rod 11 to rotate, so that the screw rod 11 drives the limit block 12 to move, so that the limit block 12 is separated from the injection mold 4;

[0042] The injection mold 4 is lifted up to realize quick dismantling. Compared with the existing screw installation, the purpose of quick dismantling can be achieved. When the baffle tube 7 is damaged and corroded, the screws 8 are removed to take out and replace the baffle tube 7 separately.
