Abstract
The invention provides a pressure casting split type punch injection device which comprises a punch, a charging barrel, an injection cylinder, a base and a push rod. According to the injection device, the punch is a split type punch formed by sleeving a plurality of sub-punches with different or identical radial size or section shape; and the assembling relationship is that the plurality of sub-punches with different or identical radial size or section shape are sequentially arranged in a sleeving manner from interior to exterior according to increasing radial sizes and are in axis coincidence with one another, and every two adjacent sub-punches are in clearance fit. According to the invention, a split type structure of the punch is realized, the multiple sub-punches can independently move relative to one another, and different pressures can be applied to different parts of the casting, so that the punch can directly act on the casting in shape. In the mold filling process, molten metal can be pushed into the cavity according to a set sequence according to demands of the casting, which is very favorable for forming composite materials. Therefore, the casting quality can be effectively improved.
Description
Technical field
The present invention relates to compression casting equipment, the Split punch injection dress of a kind of compression casting
Put.
Background technology
Compression casting, in die cavity, molten metal is applied certain pressure so that casting forming solidifying
A kind of process.Injection device is the key core mechanism in compression casting equipment, it is provided that from metal
Liquation is full of die cavity to mechanical pressure required in complete process of setting.Injection device is mainly by barrel and punching
Head composition, in injection process, it is generally required to be first poured in the middle of barrel by molten metal, passes through drift
Motion molten metal is pushed in the middle of mold cavity, complete cavity filling process, and provide in process of setting
Pressure, until foundry goods solidifies completely.
During compression casting, drift provides from filling type to the whole pressures needed for pressure maintaining period medium casting
Power.Can drift provide required mechanical pressure to have conclusive impact to casting quality.Cast at pressure
In making, owing to the distance of foundry goods different parts Yu drift has dividing of distance so that drift in process of setting
Pressure effect to foundry goods is inconsistent, and it is preferable that this causes being difficult to obtain each position mechanical performance concordance
Foundry goods, particularly, the work surface of usual foundry goods is from drift farther out so that the mechanical performance of foundry goods work surface
Mechanical performance less than material cake position.Additionally, shrinkage cavity and porosity common in compression casting, surface cold shut
Etc. mass defect, also pressure effect deficiency with drift has direct relation.
Current drift is unitary structure, it is impossible to foundry goods different parts is applied different pressures is to cause
The main cause of problem above, this also makes the problems referred to above never obtain in compression casting well
Solve.Disclosing a kind of Combined die-casting punch in Application No. 201110249209.8 patent, it is designed as
Composite structure, is divided into cylindric matrix and is coated on two major parts of working lining of outside, and matrix is adopted
Cylinder iron, working lining then uses beryllium bronze alloy material, and this structure is ensureing drift work surface formedness
Under conditions of energy, reduce manufacturing cost.One at Application No. 201510767117.7 patent disclosure
In technical scheme, drift includes agent structure and two parts of sleeve, sleeve medial wall and drift lateral surface
Sealing is slidably connected, and punch body lateral surface offers helicla flute, the water inlet of drift and outlet with
Helicla flute is connected, and this punch structure cooling water channel space is little, intensive, can significantly improve drift
Cooling effectiveness.Although above-mentioned two technical scheme has all carried out certain improvement in the structure of drift, by
The monomer structure of drift is changed into composite structure, but has the following disadvantages:
(1) although above-mentioned two technical scheme drift has composite structure, but layer structure is mainly
Improving the wearability of drift or improve cooling effect, layer structure and endothecium structure be to be fixed together
, its essence or unitary structure, it is impossible to realize mutual self-movement, also cannot realize foundry goods
Different parts applies the function of different pressures.
(2) molten metal can only be pushed away in cavity filling process by the structure of above-mentioned two technical scheme drift together
Enter die cavity, it is impossible to need to push molten metal sequentially die cavity according to foundry goods.
(3) unitary structure drift is in forming process, and foundry goods and punch contact surface cannot be as foundry goods
Useful shape, forcer position is usually formed material cake, becomes the waste material in foundry goods, causes waste of material.
Summary of the invention
The invention aims to overcome the deficiency of existing compression casting injection device, for realizing foundry goods
Different parts applies the effect of different pressures, it is provided that the Split punch injection device of a kind of compression casting.
To achieve these goals, the present invention uses following measure:
A kind of Split punch injection device of compression casting, including drift, barrel, injection oil cylinder, pedestal,
Push rod, it is characterised in that: drift described in this injection device is different by several radial dimensions and cross sectional shape
Or identical sub-drift suit becomes Split punch, assembly relation is: several radial dimensions and cross section
It is ascending that radial dimension pressed by the similar and different sub-drift of shape, the most successively suit axis weight
Close, in clearance fit between adjacent sub-drift.
Described each sub-drift connects with corresponding push rod respectively, and push rod connects with corresponding crossbeam, accordingly
Crossbeam is connected with the piston of corresponding each injection oil cylinder respectively, in order to each injection oil cylinder is driven respectively by crossbeam
Dynamic corresponding sub-drift.
Described sub-drift cross sectional shape is column type or annular type or external tooth type or inner tooth type.
The sub-drift of described external tooth type drift with inner tooth type is adjacent, and in engagement shape.
Described Split punch is cylinder fitting-type or dentation engagement type or ring tooth mixed type or ring ring fitting-type.
The present invention compared with prior art, has the advantage that and effect:
1, several radial dimensions of the present invention and cross sectional shape similar and different sub-drift suit form
Split punch, it is possible to according to the forming requirements of foundry goods, foundry goods different parts is applied different pressure,
Overcome drift in prior art and foundry goods can only be provided the deficiency of single pressure.
2, the present invention is promoted each sub-drift to move by crossbeam by each injection oil cylinder respectively, and is respectively son punching
Head provides thrust.Each sub-drift can with self-movement, by forming process between drift different mutual
Position so that drift can no longer be to provide the single merit of pressure to the directly generation effect of the shape of foundry goods
Can, expand the function of drift, and casting quality can be effectively improved.
3, drift of the present invention is that split-type structural can needing molten metal according to foundry goods in cavity filling process
Pushing die cavity by setting sequencing, this is extremely advantageous to the shaping of composite.
4, Split punch structure of the present invention can apply to have in the forming process of the foundry goods of hollow structure,
Sub-drift can simplify mould structure directly as core bar, and the technical scheme of how sub-drift makes directly to become
Shape shoulder hole structure is possibly realized, and simplifies the machining processes after casting forming, saves material, expands
The range of application of compression casting.
