Abstract
The utility model is composed of a pouring head cup, a straight pouring passage, a plurality of flowing grooves and a pouring head base, wherein, the strip flowing grooves are uniformly distributed around the straight pouring passage along the radial direction and in the radiate way, and can be designed into a shape with the same width and different thicknesses or partial grooves in different thicknesses. The utility model can be used on a sample mould cavity formed by a resin sand mould and sand box moulding, can be used for simultaneously testing the flowability of the same thickness and testing the change rule of the alloy flowability following wall thickness under the same technique condition, can ensure testing accuracy and raise the repeatability of testing results.
Description
The utility model relates to a kind of apperance, especially a kind of apperance that is used for the 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 the apperance of a kind of easy to use, reliable test result, beta alloy flowability simple in structure is provided.
Technical solutions of the utility model are as follows: the utility model is made of sprue cup, sprue, some flow channel, wells, flow channel is strip, radial radiation is distributed on around the sprue, and it is identical that flow channel can be designed to width, the different shape of each XOR part bar thickness of thickness.Apperance is divided into upper and lower two parts on sprue, so that moulding.During casting, molten metal to the flow channel filling, after the sample cooling, is tested filling type length and can setting up relation between length of flow and the ditch slot thickness of each flow channel through sprue cup, sprue and well.
The utility model is simple in structure, process easier, can be used for the sample die cavity that resin bonded sand mould and box moulding form, can be implemented in the flowability of testing same thickness under the same process condition simultaneously, can can guarantee measuring accuracy and the reappearance that improves test result with the Changing Pattern of wall thickness by beta alloy alloy flowability under the same process condition.
Further specify below in conjunction with accompanying drawing:
Fig. 1 the utility model structural representation
Fig. 2 the utility model A-A sectional structure synoptic diagram
The utility model is made of sprue cup 1, sprue 2, some flow channel 3, wells 4, and flow channel 3 is strip, and radial radiation is distributed on around the sprue, and it is identical that flow channel can be designed to width, the different shape of each XOR part bar thickness of thickness.On sprue 2, apperance is divided into upper and lower two parts, so that moulding.During casting, molten metal to flow channel 3 fillings, after the sample cooling, is tested filling type length and can setting up relation between length of flow and the ditch slot thickness of each flow channel 3 through sprue cup 1, sprue 2 and well 4.
Claims (2)
1, a kind of apperance of beta alloy flowability is made up of sprue cup 1, sprue 2, well 4, it is characterized in that also comprising some flow channel 3, flow channel be strip, radial radiation be distributed on sprue 2 around.
2, the apperance of this beta alloy flowability according to claim 1, its feature are that also flow channel 3 can be designed to that width is identical, the different shape of each XOR part bar thickness of thickness.
