Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 2 to Fig. 8 b, for the utility model embodiment one, a kind of 3D prints injection mold, comprise formpiston 1 and die cavity 2, formpiston 1 is provided with for the shaping forming part 11 of product 200 Internal periphery, for first cooling duct 12 of dispelling the heat to forming part 11 and the runner 13 passing into melted material.Die cavity 2 offer for the shaping groove 21 of product 200 outline and the second cooling duct for dispelling the heat to groove 21.
The outer peripheral edge shape of forming part 11 and the inner wall shape of product 200 match, the shape of groove 21 and the outer peripheral edge mating shapes of product 200.The mating shapes of the shape outside the first cooling duct 12 and forming part 11 outer peripheral edge.In the present embodiment, the shape inside the first cooling duct 12 also with the mating shapes of forming part 11 outer peripheral edge.
The above-mentioned liquid mentioned preferentially selects water, can certainly adopt other liquid refrigerants.First cooling duct 12 is positioned at the inner side of forming part 11.The formpiston 1 of the present embodiment is shaping by 3D printing technique, therefore, the shape in the outside (namely near a side of forming part 11 outer peripheral edge 111) of the first cooling duct 12 that its inside is offered can accomplish the mating shapes with forming part 11 outer peripheral edge 111, so the first cooling duct 12 can more be adjacent to forming part 11, thus injection mold is without the existence of cooling focus, heat radiation evenly, product cooling effectiveness is high, distortion is few, molding cycle is short, and output increases.
Particularly, above-mentioned first cooling duct 12 comprising access road 121 for passing into liquid, being surrounded on the circular passage 122 inside forming part and the exit passageway 123 for discharging liquid.Access road 121, circular passage 122 and exit passageway 123 connect secondary being connected; The position of circular passage 122 is corresponding with the position of forming part 11.Access road 121 and exit passageway 123 lay respectively at the dual-side of runner 13, and the length direction of access road 121 and exit passageway 123 is parallel with the length direction of runner 13.
In the present embodiment, the cross section of circular passage 122 is oval annulus, and the cross section of forming part 11 outer peripheral edge 111 is oval.Above-mentioned first cooling duct 12 more can be adjacent to forming part, thus the formpiston 1 of injection mold is without the existence of cooling focus, heat radiation evenly, product cooling effectiveness is high, distortion is few, and molding cycle is short, and output increases.
The 3D of the present embodiment prints injection mold and also comprises formpiston mold insert 3.Formpiston mold insert 3 is embedded at the top of formpiston 1, and its inside offers the runner 31 for the melted material that circulates, and the entrance of the runner 31 of formpiston mold insert 3 is connected with the outlet of formpiston 1 runner 13, and the outlet of the runner 31 of formpiston mold insert 3 is offered tapered.The Main Function of formpiston mold insert 3 runner 4 of whole injection mold is divided into two parts, so that the processing of runner 4.Formpiston mold insert 3 can be taken out processing separately when processing the runner 31 of formpiston mold insert 3, to be processed complete after assemble again, formpiston mold insert 3 and formpiston 1 need after assemble to freeze to fix at head to polish with grinding machine again.Runner 31 and the runner 13 in formpiston 1 of formpiston mold insert 3 be combined to form the ingate form in injection mold flow passage system its act on be enter in die cavity 2 for allowing the material of melting (plastic cement) fill, the product 200 of final our needs of formation.
The size of the entrance 1211 of access road 121 and the outlet 1231 of exit passageway 123 as far as possible will with template water-supply line shape with in the same size when designing, and general employing straight line circular course diameter is within the scope of 6mm ~ 12mm.Be the consistent loss to reduce fluid pressure in order to ensure liquid by its flow, flow velocity during the first cooling duct 12, the outlet of access road 121 is identical with the size of the entrance of circular passage 122 and the outlet of circular passage 122 and the cross section of exit passageway 123 entrance.In order to ensure that access road 121 and exit passageway 123 are connected with the large area water channel of two sides respectively, when designing, access road 121 and exit passageway 123 adopt special-shaped gradual change water channel design.
The circulation style of liquid is: liquid first enters the access road 121 of formpiston 1 from template Outer Tube, then, liquid upwards directly leads on the circular passage 122 at top along access road 121, liquid is divided into two groups and together flows to opposite side from the side of circular passage 122 along both direction after flowing to circular passage 122, in the process, the heat in forming part 11 is constantly taken away by liquid.Pass through exit passageway 123 after the opposite side of liquid in circular passage 122 converges to dirty, the pipeline flowed out in template by the outlet of exit passageway 123 is flowed in another injection mold again and circulates.Wall thickness between circular passage 122 and forming part 11 outer peripheral edge 111 is in the scope of 2mm ~ 6mm, and this heat that can farthest be produced in forming process by product was taken away with the shortest time with at utmost changing.
On the other hand, the shape of the second cooling duct of the die cavity 2 in the present embodiment and the mating shapes of groove 21.The second cooling duct in die cavity 2 can be arranged on the bottom of groove 21, also groove 21 can be provided with around, certainly also can around groove 21 and bottom the second cooling duct is set simultaneously, refer to Fig. 8 a, the second cooling duct 22a that shape and groove 21 bottom shape match is offered below groove 21, refer to Fig. 8 b, around groove 21, offer the second cooling duct 22b that shape and groove 21 peripheral shape match.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
