Abstract
The utility model discloses a mould provided with a waterway structure, which comprises at least a female form board and a male form board from the top down, wherein, space for products molding is preformed in the female form board and the male form board; the waterway structure comprises a sleeve body arranged in the female form board and a sleeve mandrel arranged in the sleeve body; the inside of the sleeve mandrel is provided with a glue channel used for injecting the glue; one end of the sleeve mandrel is provided with a step body; the tail end of the step body is provided with a spiral groove flow passage. With the spiral groove flow passage added on the sleeve mandrel body, during the products molding process, through injecting water flow, the water flow can surround the inside glue channel to flow, so as to evenly cool the hot glue injected into the glue channel, and avoid the phenomenon that plastic cement is attached to the inner wall of the mould, thereby improving the fraction indefective of the product; after the hot glue is injected, the hot glue can be cooled, so as to reduce the molding time of the product.
Description
Technical field
The relevant a kind of mould of the utility model is meant a kind of mould with water route structure especially.
Background technology
Common die generally comprises male model and master mold part, is the molding space of plastic cement products between this male model and master mold, when the plastic cement that utilizes injection machine to dissolve after being injected into above-mentioned molding space by Jiao Dao under the certain pressure, promptly may be molded to finished product; Above-mentioned master mold is set partly is standing part, above-mentioned male model is set partly for movable part, the pulling force by above-mentioned injection machine spurs above-mentioned male model part, and a side of above-mentioned finished product is attached on the above-mentioned male model part, and partly separate with above-mentioned master mold, promptly finish die sinking; Then, utilize the ejecting mechanism that is provided with on the mould that above-mentioned finished product is partly ejected from male model, finished product is broken away from from mould fully.
At present, the Jiao Dao of dark cartridge type injection machine is because of being subjected to the restriction of finished product center breaking face, and can't design water circuit system, therefore, in the formed product process, owing to can't evenly be cooled off, need wait it to cool off naturally, product could be taken out from mould, thereby cause process time longer.
The utility model content
Because above-mentioned problem, the purpose of this utility model is to overcome the deficiencies in the prior art and defective, and a kind of mould with water route structure is provided, and after injection moulding is finished, can adopt the method for injecting current to make its cooling at once, thereby accelerate the molding time of product.
A kind of mould that the utility model discloses with water route structure, this mould comprises caster and male model plate from top to bottom at least, and this male model plate and caster are reserved with the space that makes formed product, and described water route structure comprises: sleeve body is installed in the described caster; And the sleeve fuse, being installed in the described sleeve body, its inside offers the Jiao Dao that injecting glue is used, and is provided with step body at an end of sleeve fuse, offers the spiral groove type runner at the step body end.
More excellent, the step body place of described sleeve fuse offers water inlet and delivery port, and the two ends with described spiral groove type runner link to each other respectively.
More excellent, described sleeve fuse is a metallic article.
Compared with prior art, the utlity model has following advantage:
1, the spiral groove type runner is set up in utilization on the sleeve mandrel body, in the formed product process, make current to flow by injecting current around the Jiao Dao of its inside, thereby the hot glue that injects in the glue road is evenly cooled off, the phenomenon of avoiding plastic cement to adhere to mould inner wall produces, thereby has improved the yield of finished product;
2, utilize this water route structure, can after hot glue injects fully, can carry out cooling processing, thereby reduce the molding time of product.
Description of drawings
Fig. 1 is the cross-sectional view of the mould with water route structure that the utility model disclosed.
The specific embodiment
For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 1, be the cross-sectional view of the mould that the utility model disclosed with water route structure.This mould comprises caster 11 and male model plate 12 from top to bottom at least, and this male model plate 12 and caster 11 be reserved with the space 13 that makes formed product, and wherein, described water route structure comprises: sleeve body 21 is installed in the described caster 11; And sleeve fuse 22, be installed in the described sleeve body 21, its inside offers the glue road 221 that injecting glue is used, end at sleeve fuse 22 is provided with step body 222, offer spiral groove type runner 223 at step body 222 ends, described step body 222 places offer water inlet 2221 and delivery port 2222, and the two ends with described spiral groove type runner 223 link to each other respectively.
During converted products, after utilizing plastic cement that injection machine will dissolve under certain pressure, to be injected into above-mentioned molding space 13 by described glue road 221, the flow control valve of fetching boiling water, current are flow in the described spiral groove type runner 223 by described water inlet 2221, flow out via described delivery port 2222 at last, because described spiral groove type runner 223 is for being close to the helical form design in described glue road 221, and described sleeve fuse 22 is a metallic article, therefore, can be to the processing of lowering the temperature uniformly of the hot glue in the described glue road 221, the phenomenon of avoiding plastic cement to adhere to mould inner wall produces, thereby has improved the yield of finished product; And hot glue can carry out cooling processing after injection, thereby reduces the molding time of product.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by claim of the present utility model.
Claims (3)
1, a kind of mould with water route structure, this mould comprises caster and male model plate from top to bottom at least, and this male model plate and caster be reserved with the space that makes formed product, it is characterized in that described water route structure comprises:
Sleeve body is installed in the described caster; And
The sleeve fuse is installed in the described sleeve body, and its inside offers the Jiao Dao that injecting glue is used, and is provided with step body at an end of sleeve fuse, offers the spiral groove type runner at the step body end.
2, the mould with water route structure according to claim 1 is characterized in that: the step body place of described sleeve fuse offers water inlet and delivery port, and the two ends with described spiral groove type runner link to each other respectively.
