Description
Technical field
The present invention relates to technical field of mold, more particularly to a kind of compression mod.
Background technology
At present, compression mod is the main technique equipment for carrying out Die Casting, and the die cavity of compression mod is generally by middle neutron, fixed
Position circle bushing and movable neutron etc. cavity part is constituted, yet with the extrusion process Demand Design and dress of each cavity part
Limited with mode etc., tend not to it is general, this cause produce different size a series of products when, be required to be replaced by phase therewith
The cavity part of matching.This is brought many problems among actual production：First, enterprise generally requires to have many molds,
For example, producing a series of rotor of 5 kinds of length specifications using the mould of the chamber of a mould five, it is desirable to middle neutron, positioning
Each five kinds of sizes such as bushing and movable neutron are enclosed, the production cost of enterprise is added；Second, in production, change product
Die cavity and its locating element must all be pulled down replacing during specification, cumbersome, replacing construction is long, reduce the production effect of enterprise
Rate；3rd, change during cavity part, mould cooling can cause percent defective to increase；Furthermore, hot-die changes the work bar of part operation
Part is severe, endangers the health of operator.
The content of the invention
The technical problem to be solved in the present invention is to overcome the shortcomings of above-mentioned mould structure and installs that there is provided a kind of die casting
Mould, this compression mod is when producing the product of homologous series different length specification, without changing a cavity part, improves enterprise's production
Efficiency, reduces percent defective.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of compression mod, including the die cavity that mold cavity component and mold cavity component are constituted, the mold cavity component are included in being arranged at
Middle neutron in template, the centring ring bushing being arranged on moving platen, movable neutron and the iron being arranged in centring ring bushing
Core centring ring, solid plate, before die casting, iron core is placed in iron core centring ring；First positioning of the middle neutron located at middle template
In hole, the thickness a of middle neutron is less than the thickness b of middle template；The centring ring bushing is located in the second positioning hole of moving platen,
Centring ring bushing is provided with protuberance, and the protuberance can be engaged with the first positioning hole.
The compression mod of the present invention uses the structure and assembly relation of neutron and centring ring bushing in the middle of rational, specifically,
The thickness a of middle neutron is less than the thickness b of middle template so that also stayed after neutron in the middle of being set in the first positioning hole of middle template
Go out the inwall of the positioning hole of part first, the outer wall of the protuberance is engaged with the inwall of the first positioning hole and determined during matched moulds
Position.When changing the iron core of different length specification, movable neutron etc. can be toward the direction movement away from middle neutron so that die cavity
The interior parts such as iron core, therefore a set of middle neutron, centring ring bushing and movable neutron that can install are to be applicable to different length
The product of specification, without changing related parts.
Further, the middle neutron is provided with the first locating ring, and one end of the iron core is engaged with the first locating ring.
Specifically, it is engaged, realizes anterior to iron core with the first locating ring in the first locating ring of neutron in the middle of one end insertion of iron core
Fine positioning.
In order to play more preferable locating effect to iron core, prevent iron core from deforming, further, the mold cavity component is also
Including iron core centring ring, the iron core centring ring is set between iron core and centring ring bushing.Preferably, the length of iron core centring ring
Degree is less than or equal to the length of the minimum product of homologous series length specification.
Further, the iron core centring ring is connected with movable neutron.It is convenient to install with dismantling, and iron core can be carried out more
Good positioning.
Further, the mold cavity component also includes mandrel, and one end of the mandrel is connected with centre neutron, mandrel it is another
One end is inserted in core interior, and support and positioning action are played to iron core, can reduce the sub-assembly deformation in iron core.
Compression mod described in compression mod of the present invention is provided with multiple die cavities.The compression mod includes 1~N number of mold cavity component, N
≥2.Preferably, the multi-cavity compression mod is the chamber of a mould three, the chamber of a mould four, the chamber of a mould five, the chamber of a mould six etc..
Further, compression mod die cavity is centrally located on same circumference, or compression mod die cavity rectangular point of center
Cloth.
Further, die cavity is centrally located on same circumference or rectangular distribution, and corresponding between adjacent die cavity
Central angle it is unequal or apart from it is excessive when, add excessive muscle between neutron or centring ring bushing in the middle of structure identical, make various
Chamber component needs to abut as far as possible, and the shape such as middle neutron or centring ring bushing all may be designed as uniform shapes.
Further, the structure of the middle neutron of each mold cavity component of compression mod is identical, the positioning of each mold cavity component
The structure for enclosing bushing is identical.Because on the premise of die casting process conditions are preferred, each die cavity needs to abut, and often goes out as far as possible
Existing die cavity part profile is tangent and causes each die cavity part shape to unify, and the present invention is set by said structure and mounting means
Meter so that middle neutron, centring ring bushing and iron core centring ring in a multi-cavity mold needed for each die cavity, movably in
The structure of son etc. is identical, the quantity of mold component needed for effectively reducing.
Compared with prior art, the invention has the advantages that：
The present invention is engaged with the first positioning hole of middle template using centring ring bushing and positioned, and realizes production homology
The product of row different length specification only needs a set of cavity part, and locating effect is good.Creative proposes many of compression mod
Individual die cavity distribution mode, can unify the purpose of the structure snd size of mold cavity component.Mold component needed for the present invention greatly reduces
Quantity, improves the production efficiency and yield rate of enterprise, while also improving the condition of work of operator.
