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 to eject plastic cement products smoothly, make the plastic cement products demoulding smoothly.Yet, when on the product screw hole being arranged, the less screw hole in aperture particularly, if the ejecting mechanism in the employing traditional moulds ejects shaped article, particularly ejecting mechanism acts on active force on the screw hole during demoulding, and screw hole partly is damaged, and produces the shaped article flaw.In addition, the ejecting mechanism dismounting inconvenience in the traditional moulds, even can not dismounting, be unfavorable for production operation.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of mould with sleeve ejecting mechanism, it adopts has the shaped article demoulding that the sleeve ejecting mechanism will have screw hole.
The utility model has adopted following Ji Intraoperative scheme to realize: a kind of mould with sleeve ejecting mechanism, it comprises male model and master mold, and this male model and master mold are reserved with the space that makes formed product, this shaped article has the screw hole that extends evagination from a side, above-mentioned sleeve ejecting mechanism comprises: a sleeve fuse, the terminal cover of one is embedded in the above-mentioned screw hole, another terminal fixedly connected second liftout plate; One penetrates tip sleeve, is sheathed in the above-mentioned sleeve fuse, and this end of penetrating tip sleeve contacts on the hole wall of above-mentioned screw hole, another terminal fixedly connected first liftout plate; And an elastic portion, comprising a flexible member, an end of this flexible member connects above-mentioned sleeve fuse, and the other end contacts at above-mentioned second liftout plate.
Owing to adopted as above Ji Intraoperative scheme; in the mould that the utility model disclosed with sleeve ejecting mechanism; when finished product ejection device; owing to above-mentionedly penetrate the hole wall that tip sleeve contacts at screw hole; above-mentioned sleeve fuse breaks away from above-mentioned screw hole; above-mentioned screw hole is ejected, thereby has protected the hole wall of screw hole not to be damaged.Of the present utility model simple in structure, and the readily removable easy cleaning of mould, can be widely used in the plastic mould.
Description of drawings
Fig. 1 is the schematic diagram of the mould with sleeve ejecting mechanism that the utility model disclosed.
The specific embodiment
As shown in Figure 1, be the schematic diagram of the mould that the utility model disclosed with sleeve ejecting mechanism.Mould 100 of the present utility model comprises male model 110 and master mold 120, among above-mentioned male model 110 and master mold 120, is reserved with certain molding space, makes the plastic cement that is injected into be shaped to finished product 200 in this space; One of them of above-mentioned male model 110 or master mold 120 is provided with the ejecting mechanism (not shown), and this ejecting mechanism can be in die sinking, and pushing-off product 200 is separated itself and above-mentioned male model 110 or master mold 120, is beneficial to the demoulding.
Extend the screw hole 210 that is provided with an evagination on one side of the said goods 200, this screw hole 210 is for having the cylindrical wall of less internal diameter.Above-mentioned ejecting mechanism comprises a sleeve ejecting mechanism 130, is used for the screw hole 210 part ejection devices to product 200.This sleeve ejecting mechanism 130 comprises that a sleeve fuse 132, penetrates a tip sleeve 134 and an elastic portion 136.Wherein, above-mentioned sleeve fuse 132 is cylindric, and its diameter equates that with the internal diameter of above-mentioned screw hole 210 an end cover of this sleeve fuse 132 is embedded in the endoporus of above-mentioned screw hole 210, and the other end is fixed on second liftout plate 144 after connecting elastic portion 136; The above-mentioned tip sleeve 134 of penetrating is one cylindric, be arranged at the inside of above-mentioned sleeve fuse 132, an above-mentioned end of penetrating tip sleeve 134 contacts on the hole wall of above-mentioned screw hole 210, the other end and contacting on first liftout plate 142 makes this penetrate tip sleeve 134 and follows this first liftout plate 142 and do and eject motion; In addition, above-mentioned elastic portion 136 comprises a flexible member 1361 and a pad 1362, this flexible member 1361 is a stage clip, the one end is fixed on the above-mentioned sleeve fuse 132, the other end is arranged on above-mentioned second liftout plate 144, and pad 1362 is arranged on above-mentioned second liftout plate 144, and keep out a end in above-mentioned sleeve fuse 132 (can an accommodation hole that hold above-mentioned elastic portion 136 be set at above-mentioned second liftout plate 144, make above-mentioned elastic portion 136 hold with this accommodation hole in); Do when ejecting mechanism and to eject when making product 200 demouldings, the elastic force of above-mentioned flexible member 2361 makes an end of above-mentioned sleeve fuse 132 closely connect above-mentioned second liftout plate 144, make above-mentioned sleeve fuse 132 keep relative static with above-mentioned second liftout plate 144, along with the motion that ejects of this second liftout plate 144, an end of above-mentioned sleeve fuse 132 breaks away from the hole of the above-mentioned screw hole 210 of conflicting.
Above-mentioned first, second liftout plate 142 and 144 is the part of ejecting mechanism, and when the demoulding, this first, second liftout plate 142 can be with identical speed towards product 200 is moved by the direction of the demoulding with 144.When need be with product 200 demouldings of above-mentioned moulding, above-mentioned first, second liftout plate 142 and 144 is followed above-mentioned ejecting mechanism and is done and eject motion, above-mentioned first liftout plate 142 makes the above-mentioned tip sleeve 134 of penetrating towards the direction motion near the said goods 200, and the hole wall that can contact at the screw hole 210 of above-mentioned finished product 200 makes it towards moving with the demoulding away from the direction of above-mentioned ejecting mechanism; And the elastic force of flexible member 1361 in the above-mentioned elastic portion 136 makes above-mentioned sleeve fuse 132 and above-mentioned second decide liftout plate 144 and keeps relative static motion, and terminal disengaging of this above-mentioned sleeve fuse 132 contacts at above-mentioned screw hole 210.Be finished product 200 when being ejected the demoulding, an end of above-mentioned sleeve fuse 132 is no longer conflicted in the hole of above-mentioned screw hole 210, and the above-mentioned tip sleeve 134 of penetrating will first be decided the ejecting action of liftout plate 142 and produces active force above-mentioned screw hole 210 is ejected along with this.
In sum, in the utility model, owing to increased sleeve ejecting mechanism 130 in ejecting mechanism, it has preferable effect to ejecting of screw hole 210: an end of sleeve fuse 132 is sheathed in the hole of screw hole 210, and the screw hole 210 of closely conflicting is ejected it; Simultaneously, the active force that ejects of penetrating tip sleeve 134 acts on the hole wall side of above-mentioned screw hole 210 uniformly, so effectively avoided screw hole 210 impaired defective when the demoulding ejects.
