Description
Technical field:
The utility model belongs to casting field, especially relates to a kind of metal flow property testing device.
Background technology
The casting processing characteristics of metal depends on the flowability and the mold-filling capacity of liquid metal.By the flowability of test liquid metal, research improves the technology of liquid metal flowability, can improve the quality of metal casting.The type of existing measurement metal flow technology is more, as answering ditch shape, radiation shape, vacuum sample (by suction pouring), screw type, comprising the patent (99239455.4) of beta alloy flowability etc.Its shortcoming is the die cavity that each fluidity testing device has only a kind of shape, can not be fit to the measurement of different metal flowability.If will be fit to the measurement of different metal flowability, need a plurality of different moulds, cause cost to improve like this.Moreover the flowability of metal is subjected to Temperature Influence very big, and the temperature of device was all identical when said apparatus can not be guaranteed to test at every turn, thereby causes mobile measurement data inaccurate.
Summary of the invention:
The utility model has overcome the deficiencies in the prior art, and a kind of measurement of suitable different metal flowability is provided, and reliable test result is accurate, and structure is simpler, the device of the test metal flow that cost is low.
The technical solution of the utility model is as follows: the utility model comprises from the sprue cup (1) of center line symmetry dimidiation, there is a fixed sleeve (2) in sprue cup (1) outside, one internal diameter and the identical hole of sprue cup (1) external diameter are arranged in the middle of the patrix (3), one well (5) is arranged in the middle of the counterdie (4), sprue cup (1) is positioned at patrix (3) interstitial hole, the bottom of sprue cup (1) and patrix (3) bottom are at grade, water oral cavity (6) and sprue (7) in the middle of the sprue cup (1), sprue (7) links to each other with mobile shape groove (8) and well (5), the shape groove (8) that flows is vertical with sprue (7), and be the radial symmetry shape be distributed in equably sprue (7) around, one group of centre that is fixed on the counterdie (4) insert (9) is arranged between patrix (3) and the counterdie (4), constitute the shape groove (8) that flows between inserting and inserting, the bottom of counterdie (4) is provided with constent temperature heater (10).The centre insert (9) be 2 or 4 or 8, thickness is 2-15mm, be vertical bar shaped or fan-shaped, the dual-side of inserting in fan-shaped centre is shape or shaped form or bent profile of tooth or serrate or dendritic shape or waveform linearly, the centre insert (9) be fixed on the counterdie (4) by set bolt (14), the utility model is made with metal or graphite material, constent temperature heater (10) adopts the controllable silicon temperature controller, constent temperature heater is by well heater fixed head (15), and fixed head screw (16) is fixed on the bottom of counterdie (4).Characteristic according to the survey metal, the centre that select to be fit to insert (9), form various special die cavities, for convenience of folding patrix (3), patrix is provided with handle (11), and counterdie then is provided with handle (12), and the sprue cup side is provided with opening (13) so that sprue cup can be opened after the cast cooling, before cast, by the temperature that sets the preheating of metal flow property testing device also is incubated with constent temperature heater, and the fluctuation range of control temperature.
The beneficial effects of the utility model are: insert because of having adopted some sizes and thickness difference, different centre, the shape difference of the feasible shape groove that flows, thereby can be optimized according to the survey metallic character selects different centres to insert, counterdie is reusable simultaneously, can bring into play and the effect that substitutes several different counterdies, cost is reduced, simple, the easily processing of mould structure.Constent temperature heater has guaranteed under the same process condition, the test of metal flow, and the temperature of device is identical when measuring at every turn, and the measurement of having avoided producing owing to the difference of installing initial temperature is fluctuateed, and guarantees the mobile measuring accuracy and the reappearance of test surveyed.

Fig. 2 is a symmetric figure cavity structure synoptic diagram;
Fig. 3 is 8 difform shape die cavity test specimen A-A cross-sectional schematic of inserting and forming;
Fig. 4 is the casting sample that Fig. 3 difference is inserted and is combined to form.
Embodiment:
Below in conjunction with accompanying drawing the utility model patent is further described:
Select 2 or 4 or 8 centres to insert (9), form corresponding die cavity with survey metallic character fit shape, thickness, and with set bolt (14) inserted in the centre (9) be fixed on the counterdie (4).For convenience of the folding patrix, patrix is provided with handle (11), and counterdie then adopts handle (12) to move.Before cast with constent temperature heater (10) by the temperature that sets to preheating of metal flow property testing device and insulation, constent temperature heater adopts the controllable silicon temperature controller to carry out temperature control, fluctuation range＜1 of control temperature ℃.
The utility model can guarantee mobile measuring accuracy and improve the reappearance of test, and some shape slot thicknesses are identical, stream shape different mobile shape groove be the radial symmetry shape be distributed in equably sprue around, during casting, molten metal through sprue cup, sprue and well to mobile shape groove filling, after sample solidified cooling, the filled with metal length of measuring each mobile shape groove promptly reaches filled flowability and the hot crackability that the type quality can contrast metal.
