Abstract

The utility model comprises a pouring cup, pins, an opening, a handle, an upper mould, a lower mould, a lifting handle and also a radiate mould cavity, wherein, the pouring cup is symmetrically split into halves from the central line, and two half modules are positioned by the pins; the outer margin of a joint surface of the two half modules is also provided with the opening. The pouring cup is arranged on a convex table of the upper mould provided with the fixed handle; the lifting handle is arranged on the lower mould. A fluidity testing device of the utility model with an obvious effect can ensure the measuring accuracy of the fluidity and raise measuring repeatability.

Description

The device of beta alloy flowability

The utility model relates to a kind of device, especially a kind of device of beta alloy flowability.Belong to the Measuring Technique for Casting field.

The test of liquid towards metal flow and mold-filling capacity in the casting process, and test value analyzed and researched, proposing effective process is one of gordian technique that improves casting quality.Usually, adopt the method for cast " mobile sample " to measure the flowability and the mold-filling capacity of liquid metal (alloy), the length of flow after solidifying with mobile sample or fill flowability and the mold-filling capacity that the type thickness is represented alloy.The type of mobile sample is a lot, as spirality, U type, vacuum sample (by suction pouring), floral disc shape, wedge shape etc.Wherein, also there is obviously deficiency in each for floral disc shape specimen shape complexity, making difficulty, other shapes.The triple helical line alloy flowability determinator of Chinese patent 88204038, adopt spiral sample to be designed to pour into a mould concentric three helixes, thereby guaranteed mobile test under process conditions such as same casting mold, chemical constitution, pouring temperature by same sprue gate; Employing designs a special-purpose pouring basin apperance on cast gate, thereby has improved the stability of pouring head, still, this device still can not the beta alloy flowability with the situation of change of wall thickness, and its apperance shape complicated, make difficulty.

The purpose of this utility model is to overcome the defective of prior art, and a kind of reliable test result is provided, the device of the better simply beta alloy flowability of structure.

The technical solution of the utility model is as follows: the utility model comprises: sprue cup, pin, opening, handle, patrix, counterdie, handle, also comprise radiation shape die cavity, the utility model adopts metallic to make metal mold fluidity testing device, sprue cup is from center line symmetry dimidiation, locate this two halves module with pin in position, outer rim place on the two halves module involutory surface also establishes an opening, so that the cast back separates this two halves module with instrument, sprue cup is placed on the boss of patrix, fixing handle is for convenience of the folding upper die and lower die on the patrix, handle then designs for making things convenient for counterdie to move, and metal mold is preheated to the temperature of requirement before cast.The radiation shape die cavity of metal mold comprises that sprue cup chamber, sprue, flow channel, well constitute, flow channel is strip, and some mobile grooves that width is identical, thickness is different or part bar thickness is different be the radial radiation shape be distributed in equably sprue around, during casting, metal (alloy) liquid through sprue cup, sprue and well to the flow channel filling, after sample solidified cooling, the packed type length of measuring each flow channel can be set up the relation between length of flow and the ditch slot thickness.

The utility model fluidity testing device has significant effect, simple in structure, the handling ease of metal type dies; Guaranteed under the same process condition (alloying component, pouring temperature, pouring head etc.), the flowability of beta alloy, can realize measuring simultaneously under the same process condition flowability of same thickness, can can guarantee mobile measuring accuracy and improve the reappearance of test with the rule of wall thickness change by beta alloy alloy flowability under the same process condition.

Further describe below in conjunction with accompanying drawing:
