Technical field
The present invention relates to a kind of injection mold, relate in particular to a kind of injection mold of built-in cooling line, belong to the injection mold technical field.
Background technology
Injection mold is a kind of instrument of producing plasthetics, is also the instrument of giving plasthetics complete structure and accurate dimension.Injection mold is comprised of dynamic model and cover half two parts, dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, cover half is arranged on the fixed form of injection (mo(u)lding) machine, dynamic model and cover half closed formation running gate system and die cavity during injection moulding, and during die sinking, dynamic model separates in order to take out plastic products with cover half.
In injection moulding process, the variations in temperature of mould can be brought different impacts to different materials.For thermoplastic, the mold temperature height a bit is conducive to improve surface quality and mobility, but can extend cool time and injection cycle; Mold temperature is low a bit can be reduced in the contraction in mould, but can increase the shrinkage factor of moulding after the demoulding; And, concerning thermosetting plastics, high any mold temperature can reduce circulation timei.As can be seen here, the mould temperature is all very crucial to cost and the quality of controlling Shooting Technique.The cooling stage after mold injection completes particularly, once cooling not in place, the phenomenon that can make injecting products deform, rupture, cause the waste of resource and manpower.
Summary of the invention
For the demand, the invention provides a kind of injection mold of built-in cooling line, this injection mold structure is reasonable in design, the water circulation pipe of setting up in die ontology can play good cooling effect to injection-molded item, and cooling procedure is continuous, cooling effect is even, has guaranteed the end product quality of injection-molded item.
The present invention is a kind of injection mold of built-in cooling line, this injection mold comprises upper die and lower die, the inner injection moulding die cavity that forms during matched moulds, material hole is offered at the top of patrix, in described upper and lower mould, water circulation pipe is set respectively, two water circulation pipe conductings when matched moulds, between described water circulation pipe, adopt pore to connect, described counterdie upper surface arranges protruding tubular construction, and described patrix lower surface arranges the shrinkage pool structure, between described protruding pipe and shrinkage pool structure, is matched in clearance.
In a preferred embodiment of the present invention, described water circulation pipe is the ring pipe structure, and the distance between this ring pipe and mould outer wall and injection moulding die cavity is than being about 2:1.
In a preferred embodiment of the present invention, the water circulation pipe in described counterdie is offered blasthole in its underpart.
In a preferred embodiment of the present invention, the water circulation pipe in described patrix sets out water hole at an upper portion thereof.
In a preferred embodiment of the present invention, the water (flow) direction in described counterdie water circulation pipe is counterclockwise, and the water (flow) direction in the patrix water circulation pipe is clockwise.
In a preferred embodiment of the present invention, described blasthole and apopore are arranged on same straight line.
In a preferred embodiment of the present invention, the current in described water circulation pipe are externally under the water pump effect, and its flow control is at 0.05m/s.
In a preferred embodiment of the present invention, the material of the ring pipe in described water circulation pipe is chromium-copper, and the material of protruding pipe and shrinkage pool structure is stainless steel.
The present invention has disclosed a kind of injection mold of built-in cooling line, and this injection mold structure is reasonable in design, the effect uniqueness, and the water circulation pipe of setting up in upper and lower die body can play good cooling effect to injection-molded item; Simultaneously, the water circulation pipe switching performance is stable, and sealing property is high, makes cooling procedure more smooth, and cooling effect evenly, fully, has been guaranteed the end product quality that injection-molded item is good.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the injection mold of the built-in cooling line of the embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, patrix, 2, counterdie, 3, the injection moulding die cavity, 4, material hole, 5, protruding pipe, 6, shrinkage pool, 7, ring pipe, 8, blasthole, 9, apopore.
 
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Fig. 1 is the structural representation of the injection mold of the built-in cooling line of the embodiment of the present invention; This injection mold comprises patrix 1 and counterdie 2, the inner injection moulding die cavity 3 that forms during matched moulds, material hole 4 is offered at the top of patrix 1, in described upper and lower mould, water circulation pipe is set respectively, article two, water circulation pipe conducting when matched moulds, adopt pore to connect between described water circulation pipe, described counterdie 2 upper surfaces arrange protruding pipe 5 structures, described patrix 1 lower surface arranges shrinkage pool 6 structures, between described protruding pipe 5 and shrinkage pool 6 structures, is matched in clearance.
