Abstract

The utility model relates to a mould die for moulding gear-teeth by liquid mould forging, in particular to a changeable mould die for moulding gear-teeth by liquid mould forging, comprising an upper mould part and a lower mould part. The changeable mould die for moulding gear-teeth by liquid mould forging is characterized in that the upper mould part comprises an upper mould plate (1), a shim plate (2), a core-retainer plate (3), a core (4), an elastic pressing plate (5), an upper mould insert block (6), a spring (7), a stripper bolt (8) and a guide sleeve (9); the lower mould part comprises a guide post (10), a lower mould sleeve (11), a lower mould (12), a lower mould insert block (13), a lower mould plate (14) and a push rod (15). Compared with the prior art, the utility model has advantages that the moulding requirement of vivid external profile of the liquid mould forging of the gear-teeth with high precision, compact inner structure and favorable mechanical property is satisfied with simple structure of the mould die and reliable motion; when the mould parts of the mould die are changed, liquid mould forging can be made to the gear-teeth of zinc alloy, aluminum alloy and copper alloy with different dimensions or different types with broad application.

Description

A kind of mould of liquid forging formed gear of replaceable mould
(technical field)
The utility model relates to a kind of mould of liquid forging formed gear, especially a kind of mould of removable liquid forging formed gear.
(background technology)
The method that machining is shaped that general the employing directly of gear forming is shaped with the bar machining, or forges gear blank---machining is shaped, or the cast gear blank---.Then production efficiency is low but directly be shaped with the bar machining, and the processing cost height forges and to process that then production efficiency is lower, processing cost is higher, and casting processes that then the gear density is low, and intensity, hardness are low, plasticity, poor toughness, service life of gear is low, can not satisfy the requirement of heavy duty running.
(summary of the invention)
The utility model has overcome deficiency of the prior art, a kind of mould of removable liquid forging formed gear is provided, liquid metal is poured into mold cavity, shaping, crystallization under the high pressure effect, solidify, thereby obtain the liquid forging formed gear, and more the forming part of mold exchange can different gear or the different gears of type of liquid forging forming dimension.
The utility model is achieved by following technical proposals, the mould of this removable liquid forging formed gear is installed on the general hydraulic press of three beams, four posts, it is made up of part of the upper die and part of the lower die, cope match-plate pattern, backing plate, core fixing plate, core, suppress that plate, patrix are inserted, spring, discharging screw, guide pin bushing constitute the part of the upper die, guide pillar, lower die-sleeve, counterdie, counterdie are inserted, lower bolster, push rod constitute the part of the lower die; The patrix that separates of patrix shaped portion insert and core between connect with suppressing plate, spring, discharging screw; The guide pillar, the guide pin bushing guiding that are arranged on the upper and lower template are arranged, to guarantee accurate matched moulds between the upper and lower mould; The gradient that is provided with suitable for reading of counterdie guarantees that patrix is inserted accurately to import counterdie; The forming part core of mould, patrix are inserted, counterdie, counterdie are inserted, push rod is made with mold heat steel 3Cr2W8V or 4Cr5MoSivl; More forming part core, the patrix of mold exchange are inserted, counterdie, counterdie are inserted, push rod can the different gear of liquid forging forming dimension; Gear that more forming part core, the patrix of mold exchange are inserted, counterdie, counterdie are inserted, push rod is can the liquid forging shaping type different such as roller gear, conical gear; Mould can liquid forging shaping kirsite, aluminium alloy, Cu alloy material gear.
The utility model its beneficial effect compared with prior art is: mould structure is simple, and reliable in action satisfies gear liquid forging part appearance clear-cut, precision height, dense internal organization, the forming requirements that mechanical property is good; But more the forming part liquid forging forming dimension difference of mold exchange or the different gear of type, the scope of application is wide.

Among the figure: cope match-plate pattern (1) backing plate (2) core fixing plate (3) core (4) suppresses plate (5) patrix (6) spring (7) discharging screw (8) guide pin bushing (9) guide pillar (10) lower die-sleeve (11) counterdie (12) counterdie (13) lower bolster (14) push rod (15) of inserting of inserting
(specific embodiment)
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
The mould of liquid forging formed gear shown in Figure 1, during press molding, the patrix elder generation of inserting contacts with liquid metal, makes it initial shaping.Along with the decline of moved cross beam, core progressively inserts liquid metal, makes it further compacting, feeding, under high pressure solidifies fully until liquid metal.After the gear liquid forging was shaped, the hydraulic press moved cross beam drove on the part of the upper die and rises, because the effect of spring, core is deviate from from the liquid forging gear earlier, and then rise on the whole part of the upper die, rising to certain altitude, the drive push rod of taking blame for others under the hydraulic press ejects gear liquid forging part.
During work shown in Figure 2, the part of the upper die that the hydraulic press moved cross beam drives cope match-plate pattern, backing plate, core fixing plate, core, suppresses plate, patrix is inserted, spring, discharging screw, guide pin bushing are formed rises to certain altitude, with quantitative spoon melted liquid metal is poured into mold cavity, shown in Fig. 2 left side, the hydraulic press moved cross beam drives the part of the upper die and descends matched moulds, pressurization, the pressurize certain hour, liquid metal under high pressure is shaped, and under the high pressure effect crystallization and freezing, shown in Fig. 2 right side.During press molding, the patrix elder generation of inserting contacts with liquid metal, makes it initial shaping.Along with the decline of moved cross beam, core progressively inserts liquid metal, and further compacting, feeding are under high pressure solidified fully until liquid metal.
After gear liquid forging shown in Figure 3 is shaped, the hydraulic press moved cross beam drives on the part of the upper die and rises, because the effect of spring is deviate from earlier core from the liquid forging gear, and then rise on the whole part of the upper die, rise to certain altitude, taking blame for others under the hydraulic press drives the push rod rising, and gear liquid forging part is ejected counterdie, after taking out the liquid forging part, the drive push rod of taking blame for others under the hydraulic press is returned to original position, and mould begins next circulation through cleaning, spraying lubricant.
