Abstract
The utility model relates to a separate water cooling plant of an aluminum piston mould core module, which comprises a core module and a water connecting pipe, wherein, the core module comprises an upper module and a lower module which are connected by a connecting piece, and the upper module and the lower module are internally provided with a separate water cooling hole cavity module which is connected with the water connecting pipe. Through utilizing the separate water cooling hole cavity module, the separate water cooling plant reaches fine commonality, and achieves easy disassembly and replaceability. An insulated space is left between the separate water cooling hole cavity module and the core module, and the upper and the lower ends of the insulated space are in clearance fit, thus, on the cooling mode, the cooling capability to the body of the core module is reduced on the one hand, thereby being favorable to improving the tightness of the skirt section organization; on the other hand, a water cooling unit directly participates in the forming of a piston casting, thereby improving a macroscopic structure at the top of a piston roughcast and a metallurgical microscopic structure. The usage time for normal production of the module is 3 to 5 times of the prior art, and reaches 8 to 10 months. A cooling water channel is easy to be disassembled, cleaned or replaced when the adhesion of scale deposit happened, and the normal production time is basically not occupied.
Description
Technical field
The utility model relates to the water cooling plant on a kind of aluminium casting for piston machine mould core, especially a kind of independent water cooling plant of aluminium casting for piston machine mould core.
Background technology
In the process of setting of piston foundry goods after cast in the aluminium casting for piston machine mould, there is water cooling plant that core is carried out water flowing cooling by casting machine PLC established procedure, promptly goes here and there water for cooling, so that control core temperature and casting solidification order.At present, the water cooling plant of core is directly to offer a water-cooled vestibule on core, settles the string water pipe in the chamber, and the water-cooled vestibule connects sealing and forms the recirculated cooling water road with fine thread with the string water pipe.This cooling device is poor to the cooling effect of the thick big heat energy-saving position of core top piston foundry goods, and the ability of adjusting the casting solidification order is low; Easily stopped up poor reliability after using a period of time by incrustation scale; Not quick detachable and cleaning and can't be changed, and versatility is bad, thereby can influence mould production time and service life.After cooling water channel is obstructed gradually, can causes the loose and metallographic microstructure deterioration of piston blank top macrostructure because of cooling capacity descends, thereby reduce the piston blank inherent quality, cause foundary loss in batches when serious.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of good cooling results, mould service time long, be easy to the aluminium Piston mould core independence water cooling plant dismantling, clean or change.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of aluminium Piston mould core independence water cooling plant, comprise core and string water pipe, described core comprises the upper die and lower die that connect by connector, be provided with independent water-cooled vestibule mould in the upper die and lower die, independent water-cooled vestibule mould is connected with the string water pipe.
Described upper die and lower die connect by bolt, locate by key and keyway on mating surface.
Described independent water-cooled vestibule mould comprises die body, is provided with cavity in the die body, is provided with the water inlet pipe of an end opening in the middle of the cavity, and the water inlet pipe other end is connected with water inlet on the die body, also is provided with the delivery port that is communicated with cavity on the die body.
Described independent water-cooled vestibule mould is arranged in the middle of the core, and and core between be provided with insulated space, independent water-cooled vestibule mould by straight pin and piston core mold shaft to the location, independent water-cooled vestibule mould and patrix adopt matched in clearance at the two ends up and down of insulated space, and reserve the expansion joint of expanding with heat and contract with cold and causing between the counterdie.
Described string water pipe comprises water inlet pipe and outlet pipe, water inlet pipe and outlet pipe respectively with independent water-cooled vestibule mould on entery and delivery port connect sealing and form the recirculated cooling water road with fine thread.
The utility model adopts the core independence water cooling plant of the aluminium casting for piston machine mould of said structure, reaches good versatility by the independent water-cooled vestibule mould that uses the series standard size, adopts stand-alone configuration to satisfy its quick detachable and convertibility.Adopt the long-pending circulation waterway of increasing overflow section to improve its cooling effect, improve the ability of regulating the casting solidification order.Leave insulated space between independent water-cooled vestibule mould and the core, adopt matched in clearance at the two ends up and down of insulated space, fit dimension can adopt Φ
, basic size Φ wherein chooses according to the difference of series standard size,
Be that standard of tolerance cooperates, can be according to the basic size Φ acquisition of tabling look-up.On refrigerating mode, reduced on the one hand cooling capacity like this, thereby in the process of setting of piston foundry goods, the skirt section has been set up by appearance to the thermograde that internal layer progressively increases, and helps improving skirt section dense structure degree to the core body; The water-cooled unit is participated in the piston casting forming directly on the other hand, contacts with the thick large part of piston cast top, and cooling water is concentrated direct-cooled to thick big heat energy-saving position, to improve piston blank top macrostructure and metallographic microstructure.The utility model advantage compared to existing technology is: this free-standing cooling device can be realized the good cooling to the piston foundry goods, and macrostructure and metallurgical microstructrue can improve about a grade.The mould ordinary production is 3～5 times of prior art service time, reaches 8～10 months.Be easy to dismounting, cleaning or replacing after cooling water channel generation incrustation scale sticks, do not take the normal production time substantially.Therefore, this device has highly application value.
