Abstract
The invention relates to a cooling waterway which is suitable for a mold structure. The mold comprises a female die plate provided with a female model core provided with a mold core. The mold core protrudes out of the surface of the female model core; wherein, the cooling waterway is arranged in the mold core and is tabular. Therefore, the cooling waterway can cool the interior of products as the cooling waterway is arranged in the mold core. And the cooling waterway has large cooling surface and is suitable for relatively narrow box-shaped products as the cooling waterway is tabular, Compared with the prior art, the cooling waterway can achieve better cooling effect, thus effectively solving the problem that the heat sealing scar is easily generated on the surfaces of the products when the current cooling waterway cools and molds the relatively narrow box-shaped products. The cooling waterway is easy to realize, has simple structure and better popularization value.
Description
[technical field]
The present invention relates to a kind of cooling water channel, especially a kind of cooling water channel structure that is applied to expedite product cooling forming in the mould applications.
[background technology]
The palm electronic product adopts plastic casing or almag housing more at present, these housings mostly exquisite appearance, feel are good, and in production procedure, these housings are many finishes its forming process by mould, so die molding process is directly connected to the aesthetic measure of these housings.
Mould molding comprises following step: at first melten gel is injected in the die cavity of mould; Cooling forming; Die sinking ejects shaped article.Cooling forming is as the important ring in the die molding process, and the quality of cooling effect directly influences the aesthetic measure of shaped article, in the prior art, realizes by the water route in the mould the cooling of shaped article is many.Present cooling water channel is located on the interior die cavity of the mould position on every side more, after melten gel is injected into die cavity, because water body in cooling water channel is in the process of continuous flow circuit around it at this moment, so can reduce the temperature of melten gel rapidly, thereby forming process of expedite product.
Yet, the processing method of existing cooling water channel mostly is drilling machine processing, also promptly the cross section of existing cooling water channel is circular, though, when narrower, adopt its water route cooling surface of circular cooling water channel less for box-like finished product and product inside though this kind cooling water channel has versatility, can not reach the cooling requirement well, easily cause cooling effect not good this moment, thereby cause product surface to form weld mark, so that influence product quality and attractive in appearance.
[summary of the invention]
In view of above problem, the invention provides a kind of cooling water circuit, when being carried out cooling forming, narrower box-like product easily cause product surface to form the defective of weld mark to solve the existing mold cooling water channel.
For reaching above-mentioned purpose, cooling water circuit provided by the present invention, be applicable to a mould structure, this mould comprises a caster, this caster is provided with a mother module core, and this mother module core is provided with a core, and this core protrudes this mother module core surface, wherein this cooling water channel is located in this core, and this cooling water channel is flat.
So, because of cooling water channel is located at core inside, so cooling water channel can cool off product inside, and this cooling water channel is flat, thus its cooling surface is bigger and suitable box in to narrow box-like product; Compared with prior art, this cooling water channel can reach better cooling effect, easily causes product surface to form the problem of weld mark thereby can effectively solve when existing cooling water channel carries out cooling forming to narrower box-like product; This cooling water channel is simple in structure, is easy to realize having good popularization value.

[specific embodiment]
Understand for structure of the present invention, composition and technical characterictic being had further, be elaborated below in conjunction with accompanying drawing:
See also Fig. 1, shown in Figure 2, respectively cooling water channel structure of the present invention mould structure schematic diagram of living in and this mould structure decomposing schematic representation; This mould comprises a caster 10, and this caster 10 is provided with a mother module core 20, and this mother module core 20 is provided with a core 30, this core 30 protrudes mother module core 20 surfaces, and this core 30 is box-like in the present embodiment, is applicable to the box-like product 40 of moulding, as shown in Figure 3, in the present embodiment, this product 40 is the pair of lamina box, and its height of every layer is all less, and its degree of depth is darker, corresponding with this product 40, core 30 also is divided into two-layer, and its every layer thickness is also less.
Because of product 40 is box-like, so if will reach better cooling effect, not only to around this product, establish cooling water channel, also should in core, establish cooling water channel, the product surfaces externally and internally all can be cooled off rapidly, as shown in Figure 3, be provided with some groups of cooling water channels 31 in this core 30, be two groups in the present embodiment, one deck of each group and corresponding product.
See also Fig. 2, shown in Figure 3, wherein Fig. 3 is a cooling water channel schematic diagram of the present invention; The road 31 of cooling shown in the figure ' be not to be an entity, it is corresponding with cooling water channel 31, water route flow schematic diagram for cooling water channel 31 road in core 30, as shown in FIG., cooling water channel 31 is flat 34, its cross section is that two ends are circular arc, middle rectangular key-way shape face in the present embodiment, and this cooling water channel 31 processes by line cutting technology.So, less because of core 30 every layer thickness, so then its radius is also less if be designed to circular water route, this moment, the cooling water channel cooling surface was less, in the present embodiment, and because of cooling water channel 31 Cross section Design are flat, so can effectively increase cooling surface.
These two groups of cooling water channels 31 are located in the core 30, and every group of cooling water channel 31 be connected with an outlet conduit 33 with a water inlet pipe 32 respectively, and this water inlet pipe 32 and outlet conduit 33 are located in the caster 10.So, after melten gel flow into die cavity (not shown) by charging aperture (not shown), current in the mould flow into cooling water channel 31 via water inlet pipe 32, and in cooling water channel 31 after the flow circuit, flow out from outlet conduit 33, so can reach the purpose of cooling forming, because of cooling effect better, so that the probability of weld mark appears in product surface is less.
Cooling water channel of the present invention is applicable to the moulding cooling of general box-like product, in the present embodiment, this product 40 is the box-like product of pair of lamina, so core 30 also is double-deck, cooling water channel 31 also is two groups, and in the production application process, it is promptly applicable to make suitable adjustment to core and water route structure at the concrete structure of box-like product.
Compared to prior art, cooling water channel of the present invention is flat, so that the water route cooling surface is bigger, so can Reach preferably cooling effect, be particularly useful for the moulding cooling to box-like product; Because of the present invention simple in structure, Be easy to realize, so have good promotional value in mould applications.
