Abstract
The utility model discloses a die provided with a sleeve thimble mechanism, which at least comprises a female die, a male die, a first liftout plate, a second liftout plate and a permanent seat from the top down, wherein, space which makes products molding is preformed in the female die and the male die; the inside of the male die, the first liftout plate and the second liftout plate is also provided with the sleeve thimble mechanism; the sleeve thimble mechanism comprises a sleeve core, an injection tip sleeve which is sleeved in the sleeve core and a thimble mechanism which is sleeved in the injection tip sleeve, wherein, one tail end of the sleeve core props at the lower part of the space, and the other tail end is fixed in the first liftout plate and props towards the upper part of the second liftout plate; one tail end of the injection tip sleeve props in the second liftout plate; the tail end of the thimble apparatus is fixed in the second liftout plate. A feed groove is formed in the injection tip sleeve, so as to pull out the product from the female die; with the thimble mechanism, the product can be propped out of the injection tip sleeve. The die can be widely applied in plastic dies.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of mould with sleeve ejector pin mechanism.
Background technology
When utilizing mould molding to produce plastic cement products, after plastic cement is injected into mould and moulding, need to adopt the ejecting mechanism of mould that plastic cement products is ejected, this plastic cement products can be come by breaking away from the mould.
At present, the ejecting mechanism of most of moulds is mainly by the sleeve fuse and penetrate tip sleeve and constitute, and ejects by penetrating the product of tip sleeve after with moulding.Yet because the feed channel in this traditional moulds is positioned at master mold inside, therefore, the product after the moulding sticks in the master mold easily, in actual mechanical process, is difficult to smoothly by spinning off in the mould.
The utility model content
For addressing the above problem, the utility model purpose is to propose a kind ofly can make the product after the moulding be spun off by master mold inside smoothly, and the mould with sleeve ejector pin mechanism simple in structure.
The utility model provides a kind of mould with sleeve ejector pin mechanism, this mould comprises master mold, male model, first liftout plate, second liftout plate and holder from top to bottom at least, and this male model and master mold are reserved with the space that makes formed product, the male model of this mould, the inside of first and second liftout plate also comprise the sleeve ejector pin mechanism, described sleeve ejector pin mechanism comprises: a sleeve fuse, the one end is against to the below in above-mentioned space, and another end is fixed in first liftout plate and against to second liftout plate top; One penetrates tip sleeve, is sheathed in the above-mentioned sleeve fuse, and this end of penetrating tip sleeve contacts in above-mentioned second liftout plate; And an ejector pin mechanism, being sheathed on above-mentioned penetrating in the tip sleeve, an end is fixed in second liftout plate.
More excellent, described sleeve fuse is a cylinder.
More excellent, the described tip sleeve of penetrating is a cylinder, its external diameter is consistent with the internal diameter size of described sleeve fuse.
More excellent, described sleeve ejector pin mechanism also comprises a pad, is arranged in the described holder, and contacts at the described end of penetrating tip sleeve.
Owing to adopted as above technical method, the mould that the utility model disclosed with sleeve ejector pin mechanism, when utilizing mold closing, one end of ejector pin mechanism is a little less than the bottom surface of headspace, thus, in penetrating tip sleeve, form a charging groove, thereby made the product after the moulding to penetrate tip sleeve inboard smoothly by spinning off in the master mold because of adhesion earlier, utilized ejector pin mechanism that product is ejected by penetrating in the tip sleeve again.The utility model is simple in structure, can be widely used in the plastic mould.
Description of drawings
Fig. 1 is the cross-sectional view of the mould with sleeve ejector pin mechanism 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 sleeve ejector pin mechanism.This mould comprises master mold 11, male model 12, first liftout plate 13, second liftout plate 14 and holder 15 from top to bottom at least, and this male model 12 and master mold 11 be reserved with the space that makes formed product, makes the plastic cement that is injected into be shaped to product 2 in this space; Be provided with sleeve ejector pin mechanism 3 in the described male model 12, the male model 12 of this mould, first and second liftout plate 13 and 14 inside also comprise sleeve ejector pin mechanism 3, described sleeve ejector pin mechanism 3 comprises: a sleeve fuse 31, the one end is against to the below in above-mentioned space, and another end is fixed in first liftout plate 13 and against to second liftout plate, 14 tops; One penetrates tip sleeve 32, is sheathed in the above-mentioned sleeve fuse 31, and this end of penetrating tip sleeve 32 contacts in above-mentioned second liftout plate 14; And an ejector pin mechanism 33, being sheathed on above-mentioned penetrating in the tip sleeve 32, an end is fixed in second liftout plate 14.
During the mold closing state, an end of described ejector pin mechanism 33 thus, has formed a charging groove (figure does not show) in described penetrating a little less than described tip sleeve 32 and the headspace contact-making surface penetrated in the tip sleeve 32.
During die sinking, formerly in the process that described master mold 11 is pulled away from since the product 2 of moulding some adhere to the described charging groove of penetrating tip sleeve 32, therefore, can be smoothly by the inboard disengaging of described master mold 11; Subsequently, described first, second liftout plate 13 moves towards the direction that makes product 2 break away from described male model 12 with identical speed with 14, is about to described product 2 on the described ejector pin mechanism 33 by ejecting in the described male model 12.
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 (4)
