Description
Technical Field
The utility model relates to the field of machinary, specifically an injection mold.
Background
In the technical field of injection molding, for parts with larger wall thickness, cooling during injection molding is important, because if cooling is not good, shrinkage rates of the parts are different, and sizes can deviate; and to the injection molding that has the spiral hole, the degree of difficulty is bigger because, the core pulling just can unload after will rotating, has just restricted the cooling structure of the department of loosing core from this, and if the cooling is not good, can cause the adhesion of work piece and core pulling again, can't unload.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a gas-liquid mixed cooling spiral core-pulling injection mold, which comprises an upper mold and a lower mold, wherein an injection port and an injection channel are arranged on the upper mold, the lower part of the lower mold is fixed with an upper fixing plate, a screw hole is arranged on the upper fixing plate, a spiral mandrel is screwed in the screw hole, the lower part of the spiral mandrel is inserted into a through hole of the lower fixing plate, a rotating wheel is arranged in the middle of the spiral mandrel, the rotating wheel is meshed with a middle wheel, the middle wheel is also meshed with a driving wheel, the driving wheel is fixed on an output shaft of a motor, and the motor is; liquid cooling cavities are arranged beside the cavities of the upper die and the lower die, and each liquid cooling cavity is communicated with a water inlet and a water outlet; the spiral core shaft is provided with a blind hole, an air outlet pipe is arranged in the blind hole, and the height of the air outlet end of the air outlet pipe is lower than that of the upper fixing plate.
The upper fixing plate and the lower fixing plate are connected into a whole through a plurality of stand columns.
The outlet duct is in through a plurality of solid fixed ring settings in the blind hole, and solid fixed ring axial sets up the air vent.
The utility model has the advantages that: the technical scheme of gas cooling core pulling and liquid cooling of the die body is adopted, so that an excessively complex structure is avoided, the die cost is reduced, and the cooling effect is good; in addition, because the cooling effect is good, the cooling time after injection molding is reduced, and the production efficiency is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is described in detail with the following drawings, as shown in the figures, the utility model comprises an upper die 2 and a lower die 1, wherein the upper die 2 is provided with an injection port and an injection channel 3, the lower part of the lower die is fixed with an upper fixing plate 4, the upper fixing plate 4 is provided with a screw hole, a spiral mandrel 10 is screwed in the screw hole, the outside of the spiral core pulling is provided with a thread, thus a thread concave hole 9 is formed during injection molding; the lower part of the spiral mandrel 10 is inserted into a through hole of the lower fixing plate 5, the middle part of the spiral mandrel is provided with a rotating wheel 11, the rotating wheel 11 is meshed with a middle wheel 14, and two ends of a middle wheel shaft 13 are respectively fixed on the upper fixing plate and the lower fixing plate; the intermediate wheel 14 is also meshed with a driving wheel 15, the driving wheel 15 is fixed on an output shaft of a motor 16, and the motor 16 is fixed on the lower fixing plate 5; liquid cooling cavities 6 are arranged beside the cavities of the upper die 2 and the lower die 1, and each liquid cooling cavity 6 is communicated with a water inlet 7 and a water outlet 8; the spiral core shaft 10 is provided with a blind hole 18, an air outlet pipe 12 is arranged in the blind hole, and the height of the air outlet end of the air outlet pipe 12 is lower than that of the upper fixing plate, so that the spiral core shaft is guaranteed not to interfere with the air outlet pipe when moving downwards.
The upper fixing plate and the lower fixing plate are connected into a whole through a plurality of stand columns.
The outlet duct sets up through a plurality of solid fixed rings 19 in the blind hole, and solid fixed ring axial sets up the air vent to guarantee gaseous circulation.
