Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of mould with the groove product.
Background technology
The Along with people's growth in the living standard; It is more various that needed in daily life daily product also becomes; Wherein plastic product is seen everywhere in people's life especially; For example various electronic product casings, plastic cup, game pad etc. pour in the mould after when these plastic products of processing, need plastic raw materials being melted, and cooling back die sinking to be formed just can obtain needed product.And along with the update of product, it is various that its structure also becomes increasingly complex, and often needs to form various grooves usually in the product structure; During formed strip groove product, need realize through the structure of loosing core, and when product smaller; If can be big a lot of with general structure mold mold base, the cost of mould be higher.Therefore be necessary that the mold mechanism that designs a kind of compact conformation, can practice thrift cost realizes moulding and the smooth die sinking with the groove product.
The utility model content
The purpose of the utility model provides a kind of stable molding, is convenient in demoulding, compact conformation, can practice thrift the mould of the band groove product of cost.
For reaching above-mentioned purpose, a kind of mould with the groove product that the utility model provided is applicable to that moulding has the product of inner groovy; Comprise master mold and male model, its master mold also comprises die holder, is fixed in the caster on the die holder and is fixedly arranged on the mother module core in the caster, is installed with male model benevolence on its male model; The mould of this band groove product also comprises wedge post and internal core-pulling mechanism; Its internal core-pulling mechanism comprises draw-in bar, interior flexible member and is used for the inner slide of shaped article inner groovy that offer the die chamber on the male model benevolence, inner slide is slidedly arranged in this die chamber; Mother module core, male model benevolence and inner slide cooperate the die cavity that forms the confession shaped article; The direction setting that the draw-in bar edge is parallel with the inner groovy opening direction, this draw-in bar one end is fixedly connected with inner slide, stretch through out male model and being blocked in outside the male model of the other end; Interior flexible member is set on the draw-in bar and conflict with inner slide and male model respectively in two ends; Offer the inner slide draw-in groove of opening direction on its inner slide perpendicular to the inner groovy opening direction, wedge post and draw-in bar vertical setting each other, this wedge post one end is fixed on the die holder; The other end protrudes out die holder and caster and is contained in the inner slide draw-in groove, has distance between space and inner slide and the die chamber between inner slide and the die chamber greater than the said inner groovy degree of depth.
Particularly, the convexity that has the inner groovy that is used for the said product of moulding on the said inner slide.
Preferably, the end of said wedge post is formed with tapered portion, and the tapered portion of said inner slide draw-in groove and said wedge post is mated tapered shape; The tapered portion of said wedge post is contained in the said inner slide draw-in groove; When the wedge post breaks away from, because the elastic force effect of interior flexible member makes the inner slide draw-in groove be close to the tapered portion of wedge post; Break away from the product of moulding thereby inner slide is slowly slided with the disengaging of wedge post in the die chamber, make the demoulding of inner groovy more reliable and more stable.
Embodiment as the utility model; Said product also has the outer groove that is opened on the inner groovy opposition side; The mould of said band groove product also comprises the outer core-pulling mechanism that is arranged between male model and the caster, and this outer core-pulling mechanism comprises outside link, outer flexible member and be used for the outer slide of the outer groove of shaped article that its outer slide is slidingly installed on the inner slide and convexes with the projection that stretches into the outer groove that is used for shaped article in the die cavity; Outside link and draw-in bar are horizontally disposed with each other; One end of outside link forms the stiff end that is fixedly connected with outer slide, and the other end protrudes out male model and end and is formed with and stops end, and outer flexible member is set on the outside link and conflict is held with stopping of male model and outside link respectively in two ends; Run through offering groove on the outer slide, the wedge post passes groove and end is contained in the inner slide draw-in groove.
Preferably; Also comprise baffle plate; This baffle plate is arranged on male model and is fixedly connected with the caster outside and with male model, and draw-in bar and outside link pass baffle plate with articulating respectively, conflicts with inner slide and baffle plate respectively in interior flexible member two ends; Conflicting with the end that stops of baffle plate and outside link respectively in outer flexible member two ends, has distance between space and outer slide and the male model between outer slide and the male model greater than outer depth of groove.
Preferably, said interior flexible member and said outer flexible member are spring.
As stated, the mould of the band groove product of the utility model has been set up internal core-pulling mechanism and wedge post; Through utilizing inner slide to come the inner groovy of shaped article, during die sinking, the wedge post breaks away from master mold; Be that the wedge post breaks away from from the inner slide draw-in groove gradually; Owing to be provided with the interior flexible member that is set on the draw-in bar between inner slide and the male model, along with the gradually disengaging of wedge post from the inner slide draw-in groove, interior flexible member is at the product that promotes under the elastic force effect inner slide makes inner slide disengaging moulding toward interior lateral movement after; Thereby the completion demoulding; The band groove formed product mould structure compact of the utility model can effectively be practiced thrift die cost, reliably realizes formed strip groove product and conveniently successfully realizes the demoulding.
