Abstract

The invention provides a cooling water way structure of an injection mould core. The problems that according to a circular cooling water way structure of an existing injection mould core of a flat-thin-wall-shaped forming structure, cooling water way circulating is not smooth, and cooling is not even is solved. The service life of an injection mould can be effectively prolonged. The structure comprises an injection mould core body. A shape-following cooling water way is arranged in the injection mould core body, the shape-following cooling water way is arranged around a forming structure shape or along the direction of the forming structure. The forming structure of the injection mould core body comprises a flat-thin-wall-shaped forming structure with the thickness of 5-10 mm. The cooling water way structure is characterized in that the shape-following cooling water way in the flat-thin-wall-shaped forming structure is a kidney-shaped hole type pipeline, and the kidney-shaped hole height direction of the kidney-shaped hole type pipeline is parallel to a side forming face of the flat-thin-wall-shaped forming structure.

Description

The cooling water channel structure of injection mold die
Technical field
The present invention relates to 3D and print injection mold field, especially relate to the 3D printing technique field of the injection mold with flat shaping thin wall structure, be specially a kind of cooling water channel structure of injection mold die.
Background technology
In injection mold, cooling system is its core, all has important impact to the life-span of mould, the production efficiency of injection-molded item and quality.The design of injection moulding cooling water channel is the key improved injection-molded item quality, improve injection mo(u)lding efficiency.3D printing technique is applicable to the processing and fabricating of labyrinth body more, and along with the development of 3D printing technique, it is applied in Mould Machining field more and more, be particularly applied to more and more in die or mold insert along molding structure shape or move towards arrange special-shaped cooling water road or conformal cooling water route injection mold processing in.Facilitate 3D to print processing or machined because circular pipeline has, the advantages such as circulation is good, the cooling water channel of existing injection mold mostly is round tube line structure.See Fig. 1, Fig. 2 and Fig. 3, but when the molding structure of the die of injection mold, mold insert 7 or slide block is flat thin wall shape because this molding structure thickness is less, thus the diameter of circular cooling water channel 8 certainly will should reduce, thus cause the circulation of cooling water channel inner cooling water on the one hand little, current are not smooth, even can cause pipeline blockage, cooling effect is poor; Meanwhile, because the diameter of circular cooling water channel is less, cause the cooling water pressure in water route to increase, larger cooling water pressure meeting mold damage, thus reduce the service life of injection mold; On the other hand, circular pipeline tube wall and die, mold insert or slide block forming surface not parallel, circular pipeline tube wall is unequal to the distance of forming surface, thus causes shaping plastic inhomogeneous cooling even, affects the quality of product.
Summary of the invention
For the problems referred to above, the invention provides a kind of cooling water channel structure of injection mold die, it can solve the problems such as cooling water channel circulates freely, inhomogeneous cooling is even that the existing circular cooling water channel structure with the injection mold die of flat thin wall shape molding structure exists, and effectively can improve the service life of injection mold.
This technical scheme is such, it comprises injection mold die body, conformal cooling water route is provided with in described injection mold die body, described conformal cooling water route is around the molding structure arrangements of described injection mold die body or move towards to arrange along described molding structure, the molding structure of described injection mold die body comprises flat thin wall shape molding structure, the thickness of described flat thin wall shape molding structure is 5mm ~ 10mm, it is characterized in that: the described conformal cooling water route part in described flat thin wall shape molding structure is the poroid pipeline of kidney-shaped, the mounting hole short transverse of the poroid pipeline of described kidney-shaped is parallel with the side direction forming surface of described flat thin wall shape molding structure.
It is further characterized in that:
The sidewall of the poroid pipeline of described kidney-shaped is to the side direction forming surface distance d >=1.5mm of described flat thin wall shape molding structure;
Width 1.5mm≤D≤the 3mm in the cross section that described kidney-shaped is poroid, and D≤d;
The upper/lower terminal of the poroid pipeline of described kidney-shaped is circular arc.
Beneficial effect of the present invention is: the conformal cooling water route in its flat thin wall shape molding structure is the poroid pipeline of kidney-shaped, and the mounting hole short transverse of the poroid pipeline of kidney-shaped is parallel with the side direction forming surface of flat thin wall shape molding structure, when the width of the poroid pipeline of kidney-shaped is identical with original circular pipeline diameter, the cross-sectional area of the poroid pipeline of kidney-shaped is large compared with the cross-sectional area of circular pipeline, thus cooling water flow is large, good cooling results; And due to the cross-sectional area of the poroid pipeline of kidney-shaped large compared with the cross-sectional area of circular pipeline, therefore when kidney-shaped poroid pipeline width is identical with circular pipeline diameter, cooling water pressure in the poroid pipeline of kidney-shaped is less, effectively can improve the service life of injection mold; Because the mounting hole short transverse of the poroid pipeline of kidney-shaped is parallel with the side direction forming surface of flat thin wall shape molding structure, the poroid pipeline inner wall of kidney-shaped is roughly equal to the distance of the side direction forming surface of flat thin wall shape molding structure, and within the scope of control d >=1.5mm, the side direction forming surface that can ensure flat thin wall shape molding structure further not because of with cooling water channel too near and the influence of hydraulic pressure be subject in cooling water channel causes side direction forming surface to be out of shape, the service life of injection mold can not only be ensured, also can guarantee the Forming Quality of moulding; The two ends up and down of the poroid pipeline of kidney-shaped are circular arc, remain circular water route and are easy to processing and good circulation.
