Description

A kind of mould structure can changing die-cast product
Technical field
The utility model belongs to technical field of mold, is specifically related to a kind of mould structure of die-cast product.
Background technology
The die-cast product mould of prior art is all man-to-man substantially, namely a secondary mould can only a kind of product of die casting, this scheme makes out the enormous amount of molding jig, causes a large amount of manpowers, the waste of material and facility, even storage, management all to increase many inputs.
Such as Chinese Patent Application No. numbers 201410005609.8, name is called the application for a patent for invention of " a kind of aluminum alloy die-casting die ", disclose a kind of aluminum alloy die-casting die, comprise patrix, counterdie, be arranged on, guiding-positioning structure between counterdie, and be arranged on, the cooling duct that counterdie is connected with constant-temperature cooling device, described counterdie comprises the lower bolster of solid punch block, and be positioned at the fixed base plate of counterdie bottommost, described convex module is provided with the core fixing hole being through to fixed base plate bottom surface, core fixing hole is provided with threaded counterbore in the openend of fixed base plate bottom surface, shaping core is provided with in core fixing hole, the position limiting convex ring being positioned at counterbore is provided with at the root of core, counterbore internal thread is connected with the plug abutting position limiting convex ring bottom surface.The core of this mould is fixed in cored hole, and manufacture and design for a kind of product specially, it can not be used for other production, also core cannot be carried out exchanging the core for another kind of product.
Summary of the invention
The utility model technical issues that need to address are, the die casting overcoming prior art can only waste large defect to single product application, a kind of die casting that within the specific limits can be general is provided, have application motor-driven, economize on the use of funds, the advantage of convenient management.
The purpose of this utility model is achieved by following technical proposals: a kind of mould structure can changing die-cast product, comprise die holder, it is characterized in that, the die shoe that die holder comprises upper bolster and is mated, there is die cavity the centre of upper bolster and die shoe, be furnished with interconvertible core in die cavity, an auxiliary mould core is corresponding with a kind of product; The bottom of die shoe is provided with the detent mechanism of core and the bolt connecting hole of locking core, is connected with mould emptier under die shoe; The side of die cavity connects running gate system, and the runner of running gate system is communicated with die cavity, and the opposite side of die cavity is connected with gas extraction system, and gas extraction system comprises some exhaust ducts.
Select a kind of core treating the product of die casting, the core detent mechanism aimed at bottom die shoe compresses and passes through bolt-locking, the upper bolster that closes locks, the molten metal of melting is injected by running gate system, the gas be mingled with in gas in die cavity and molten metal is got rid of by exhaust duct, if need the another kind of product of die casting, only need exchange core, therefore same secondary mould can die casting multiple product, and this is especially meaningful for the series of products that profile shape is identical.
As preferably, mould emptier comprises base plate, and base plate is connected with under die shoe by cushion block, has top board between base plate and die shoe, and top board connects material discharging rod.
As preferably, running gate system is made up of vertical cast gate.
As preferably, the side of die holder has cooling water pipe access aperture.
As preferably, upper bolster and die shoe are furnished with guide pin bushing and guide pillar.
As preferably, upper bolster and die shoe are square structure, and four square angular positions are respectively furnished with a set of guide pin bushing and guide pillar.
As preferably, described exhaust duct is the structure of damped oscillation shape curve.
The beneficial effects of the utility model are:
1, save a large amount of manpowers and material, reduce taking of equipment;
2, significantly economize on the use of funds;
3, convenient management and save storage space;
Can mould be dismantled when 4, exchanging core, directly can exchange on lathe, save debug time in a large number, enhance productivity;
5, series of products production application is conducive to most.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the schematic top plan view of a kind of embodiment of the utility model, removes upper bolster in figure.
In figure, upper bolster 1; Die shoe 2; Guide pin bushing 21; Die cavity 3; Core 4; Bolt connecting hole 5; Mould emptier 6; Base plate 61; Cushion block 62; Top board 63; Running gate system 7; Vertical cast gate 71; Gas extraction system 8; Exhaust duct 81; Cooling water pipe joint 9; Product 10.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiments, the utility model is further described.
Embodiment 1: as shown in Figure 1, 2, a kind of mould structure can changing die-cast product, comprise die holder, the die shoe 2 that die holder comprises upper bolster 1 and is mated, upper bolster 1 and die shoe 2 are furnished with guide pin bushing 11 and guide pillar, upper bolster 1 and die shoe 2 are square structure, and four square angular positions are respectively furnished with a set of guide pin bushing and guide pillar.There is die cavity 3 centre of upper bolster 1 and die shoe 2, is furnished with interconvertible core 4, auxiliary mould core 4 corresponding with a kind of product in die cavity 3; The bottom of die shoe 2 is provided with the detent mechanism of core and the bolt connecting hole 5 of locking core; mould emptier 6 is connected with under die shoe 2; mould emptier 6 comprises base plate 61; base plate 61 is connected with under die shoe 2 by cushion block 62; have top board 63 between base plate 61 and die shoe 2, top board 63 connects material discharging rod.The side of die cavity 3 connects running gate system 7, running gate system 7 is made up of vertical cast gate 71, and the endoporus of the sprue bush in running gate system 7 is single cone hole structure, and the runner of running gate system 7 is communicated with die cavity 3, the opposite side of die cavity 3 is connected with gas extraction system 8, and gas extraction system 8 comprises some exhaust ducts 81.The side of die holder has cooling water pipe access aperture and cooling water pipe joint 9.
