Description
Technical field:
The invention belongs to hub mold and make the field, particularly relate to a kind of coolant equipartition device and manufacture method thereof that is used for hub mold.
Background technology:
At present, hub mold major part on the market all is provided with cooling device, simultaneously because the particularity of wheel hub structure, many spokes are arranged on the wheel hub, the transition position of spoke and wheel rim is just said thermal center point place, the concentrated place of heat, so cooling device all is that point is cold at the cooling of thermal center point, this need put cold position with coolant feed to hub mold with regard to needing a coolant equipartition device.The coolant equipartition device of prior art or be to be communicated with cooling agent by multiple-pass joint to be responsible for and a plurality of cooling agent arms; Be to be communicated with cooling agent by a separator tube to be responsible for and a plurality of cooling agent arms.But the coolant equipartition device of these two kinds of structures is in the application process of reality, because the structure of pipe joint, the influence of difference of difference on the internal diameter of each cooling agent arm and separator tube internal diameter or the like, make that the flow of the cooling agent that comes out from the cooling agent arm is always inequality, so the coolant flow of each cooling point is inconsistent in actual production process, it is the cooling velocity difference of each cooling point, and the slow excessively place of foundry goods cooling velocity is easy to generate shrinkage porosite, the too fast place of foundry goods cooling velocity is easy to generate crackle, finally cause casting yield lower, production cost is higher.
Summary of the invention:
The technical problem to be solved in the present invention is that a kind of identical coolant equipartition device of coolant flow that respectively cools off in the arm that makes is provided.
For realizing the object of the invention, the used technical scheme of the present invention is: the coolant equipartition device that a kind of following structure is provided, it comprises the cooling agent person in charge, be responsible for the entrance point separator tube that is communicated with cooling agent, at least two entrance point arms that are communicated with the entrance point separator tube, the port of export arm that equates with entrance point arm quantity, port of export separator tube and the cooling agent return duct that is communicated with port of export separator tube, described port of export arm all is communicated with port of export separator tube, be provided with cooling of a heat-exchange device formation along separate routes between an entrance point arm and a port of export arm, all be provided with a flow regulator at least on described each cooling arm along separate routes.
The quantity of described entrance point arm is seven, and port of export arm also is seven, and promptly cooling quantity along separate routes is seven.
Another object of the present invention provides a kind of manufacture method of coolant equipartition device, and it may further comprise the steps:
A, with cooling agent be responsible for be communicated with each cooling along separate routes in the entrance point separator tube connection of entrance point arm;
B, the cooling agent return duct is communicated with port of export separator tube;
C, on each cooling arm along separate routes, be provided with a flow regulator at least;
D, in each cooling along separate routes, all connect flow detector;
Load onto heat-exchange device between e, the entrance point arm in each cooling along separate routes and the port of export arm;
F, by pipeline cooling agent is responsible for and is connected on the cooling agent main pump subsequently;
G, open main pump, and the reading on the observation flow detector, regulate simultaneously each cooling along separate routes the flow regulator on arm up to the reading on each flow detector all on required same numerical value, subsequently all flow regulators all are fixed on current state;
Behind h, the dismounting flow detector, each cooling shunt middle outlet end arm is communicated with port of export separator tube.
Described flow detector is commercially available flowmeter.
Compared with prior art, the present invention is owing to be provided with flow regulator on each cooling arm along separate routes, then the flow of cooling agent in each arm all can be adjusted to identical flow, the cooling velocity that is each cooling point is all identical, eliminated that each thermal center point cooling velocity of foundry goods is inconsistent to exist too fast or slow excessively problem, make the cooling velocity of each thermal center point of foundry goods all on default cooling velocity, finished casting rate is higher, and production cost is lower; All be connected on the flow detector along separate routes in the cooling that detects flow regulator on the fashionable dress simultaneously, then the levels of precision of the flow unanimity of cooling agent in each arm is higher, be that the identical exact value of the cooling velocity of each cooling point is higher, make that organizing of each cooling point of foundry goods is more approaching, thereby make that the quality of foundry goods is more reliable; And flow regulator with the Flow-rate adjustment of each entrance point arm or port of export arm after unanimity, flow regulator is fixed on current state, then the flow of cooling agent is consistent all the time in each arm, need not when reusing to regulate again, saved human cost and shortened production process, production cost is lower.
As improvement, described flow regulator comprises and is located at the screwed hole on each cooling arm along separate routes and screws the bolt that is used to regulate flow in screwed hole, and it is less and cost is lower that then flow regulator is regulated volume simple, that take.
As further improvement, describedly flow regulator is fixed on current state is meant, stud weld in the flow regulator is connected on entrance point arm or the port of export arm, and with the part excision of bolt outside entrance point arm or port of export arm, then simple to operate, bolt after the welding is difficult for getting loose, make that the flow of cooling agent is consistent all the time in each arm, and after the part excision of bolt outside entrance point arm or port of export arm, whole flow regulator does not account for entrance point arm or the outer any volume of port of export arm, need not to be provided with in addition supporting with it space, so easy to use, cost is lower.
