Description
Technical field
The utility model relates to a kind of casting mould, relates to the casting mould that a kind of die sinking ejects workpiece synchronously specifically.
Background technology
In the Foundry Production, workpiece ejected diversified mode.In the mould of last lower open die, often use following pushing method: in the die sinking process, utilize patrix that workpiece is taken out of, the push rod through patrix ejects workpiece then, takes off workpiece, on this mode counterdie liftout attachment is not set.
There is certain defective in above-mentioned pushing method, and when the counterdie draft angle is bigger, required withdrawing pattern power hour; Aforesaid way can be realized die sinking smoothly, yet, when the counterdie draft angle less; When required withdrawing pattern power is big; Aforesaid way just is difficult to smooth die sinking, patrix occurs and can't take workpiece out of or break phenomenon such as workpiece weak part, can't steady and continuous production.This just need increase liftout attachment on counterdie.
At present, the counterdie liftout attachment that on above-mentioned pushing method, increases mainly contains hydraulic pressure and mechanical dual mode.Because operating ambient temperature is very high, hydraulic cylinder must be installed in the mould outside, and structure is loaded down with trivial details, and it is bigger to take up room, and functional reliability is lower, and is difficult to guarantee that the counterdie liftout attachment ejects synchronously when patrix is opened.One of mechanical system is when patrix is opened, through rigid member mould opening force to be passed to the counterdie liftout attachment; Realization ejects workpiece, the ejecting synchronously of counterdie liftout attachment when this mode can realize that patrix is opened, still; This structure more complicated; Part processing precision is had relatively high expectations, and matching requirements are also than higher, and job stability is difficult to guarantee.Therefore, must improve, design a kind of reasonable, practical ejecting mechanism the counterdie liftout attachment.
The utility model content
The purpose of the utility model is the above-mentioned deficiency that exists to existing casting mould counterdie liftout attachment, provides a kind of die sinking that has improved to eject the casting mould of workpiece synchronously.The counterdie liftout attachment ejected workpiece synchronously when this mould can be realized the unlatching of casting mould patrix effectively.
The technical scheme of the utility model is: said mould mainly comprises base plate, counterdie, top board, ejection ring, return bar, the collar, patrix, core rod, screw, axle and spring; Counterdie is fixed on the base plate, and core rod is fixed on the counterdie through screw, and ejecting mechanism is positioned in the cavity that is formed by base plate, counterdie and core rod; Ejection ring, axle link together through screw and top board; Spring housing is on axle; And be positioned in the counterbore of base plate; The utilization of return bar is threadedly connected on the top board, and said axle, spring and return bar are uniformly distributed with several according to actual needs on top board, and these parts are formed the synchronous ejecting mechanism of die sinking together; Collar utilization is threadedly connected on the counterdie.
Said ejection ring is a tubular construction, is installed in the annular groove of counterdie and core rod formation; Ejection ring adopts matched in clearance with contacting of counterdie, core rod, and the value of matched in clearance is at 0.1～0.2mm.The centre bore bottom of said counterdie is designed to " concavo-convex " structure, offers scallop hole at the correspondence position of top board, top board is through on " concavo-convex " structure of counterdie.The collar is installed on counterdie, and behind Ccope closing machine, collar upper surface and patrix are fitted, and play sealing function.Said spring adopts special high temperature resistant spring, can be at the medium-term and long-term steady operation of environment more than 400 ℃.
During said Ccope closing machine, push back a bar downwards, pressure is passed to spring, make the spring compression through top board and axle.When patrix was opened, the spring elongation passed to workpiece through axle, top board and ejection ring with ejecting force, ejecting synchronously workpiece when realizing die sinking.
