Abstract

The utility model discloses a slide block jacking rod mechanism of a die casting mould for a gearbox, which comprises a movable mould correspondingly matched with a fixed mould. A slide block jackingrod mechanism is arranged on the movable mould in a matched manner, a movable mould cavity and a fixed mould cavity are correspondingly arranged on the movable mould and the fixed mould, the slide block jacking rod mechanism comprises a jacking rod and a pushing plate mechanism, and the jacking rod penetrates through and slides in an inner hole of a slide block in a matched manner. The slide blockjacking rod mechanism adopts plane fractal as the jacking rod mechanism is arranged on the slide block, and during the mold opening process, the slide block slides while the jacking rod props againsta die-casting part, thereby enabling the cast to stay on the die cavities instead of escaping along with the slide block, ensuring the dimensional stability, and avoiding pull deformation. The utility model can reasonably control the eventual size variation of the die-casting parts, thereby reducing the die casting defects and the manufacturing cost and improving the production qualification rateof the die-casting parts.

Description

The slide block post rod mechanism of gear-box die casting
Technical field
The utility model relates to the design and the manufacturing technology field of die casting, especially a kind of slide block post rod mechanism of gear-box die casting.
Background technology
Die casting is a big class in the mould.In recent years, along with developing rapidly of China's automobile, motorcycle industry, the die casting industry has welcome the new period of development.But meanwhile, also comprehensive mechanical property, life-span and the mould structure etc. of die casting are had higher requirement.
Die casting is a kind of production process of precision, yet the final size that has several factors but can influence die casting changes.Change in size can be divided into linear change (mainly be owing to shrink cause) again, the mobile dislocation between mould, and die parting line, foundry goods and mould warpage, the die casting parameter is loosed core and depanning gradient etc.But there is any final size that must remember die casting to change and just depends in part on mould and die accuracy, it also has confidential relation with following factor: the normal fluctuation of mould temperature in press casting procedure, injection temperature, cooling velocity, the structure of casting stress release and mould etc.For reducing the change in size of final products, must strictly control production process, optimize mould structure.
The gear-box die casting that uses as a kind of structural member in the electric tool generally adopts the method moulding of die casting, but all there is not post rod mechanism on the general design slide block, and owing to package power on the slide block of this gear-box die casting is very big, there is not the backgauge face around the slide block again, during die sinking slide block there is the very big power of pullling, in the sliding process of slide block, can pull outward die casting like this, thereby the final size that influences die casting changes, even can be with the die casting drawing crack, and then influence die life and product percent of pass, increase the cost that mould is safeguarded.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provide a kind of final size that can rationally control die casting to change, thereby reduce the die casting defective, improve the production qualification rate of die casting, the slide block post rod mechanism of the gear-box die casting that reduces production costs.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the slide block post rod mechanism of gear-box die casting includes the dynamic model of corresponding cooperation cover half; Wherein: be equipped with the slide block post rod mechanism on the dynamic model, correspondence is shaped on dynamic model die cavity and cover half die cavity on dynamic model and the cover half, and the slide block post rod mechanism comprises push rod and rushing board mechanism, and push rod runs through and sliding fitting in the endoporus of slide block.
The technical measures of taking also comprise:
Above-mentioned slide block post rod mechanism is arranged on dynamic model one side.
Above-mentioned rushing board mechanism comprises equipped mutually push rod fixed head and push pedal, and this rushing board mechanism is fixed on the side of dynamic model, and this push rod fixed head constitutes contact-making surface with the push pedal applying and becomes 90 degree angles with the mould die joint that dynamic model and cover half applying constitute.
Compared with prior art, the utility model adopts Planar Fractal, on slide block, be provided with post rod mechanism, during die sinking, push rod withstood die casting when slide block moved, and had so just avoided foundry goods with the trend that slide block walks toward outside, and it is rested on the mold cavity, guarantee its dimensional stability, prevent to draw distortion.The final size that the utility model can rationally be controlled die casting changes, thereby reduces the die casting defective, improves the production qualification rate of die casting, reduces production costs.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 structure member explanation: foundry goods 1, push rod 2, slide block 3, cover half 4, dynamic model 5.
Shown in Figure 1, the slide block post rod mechanism of the utility model gear-box die casting includes the dynamic model 5 of corresponding cooperation cover half 4; Wherein: be equipped with the slide block post rod mechanism on the dynamic model 5, correspondence is shaped on dynamic model die cavity and cover half die cavity on dynamic model 5 and the cover half 4, and the slide block post rod mechanism comprises push rod 2 and rushing board mechanism, and push rod 2 runs through and sliding fitting in the endoporus of slide block 3.The slide block post rod mechanism is arranged on dynamic model 5 one sides.Rushing board mechanism comprises equipped mutually push rod fixed head 6 and push pedal 7, and this push rod fixed head 6 and push pedal 7 constitute on the side of binding face 5, and this push rod fixed head 6 constitutes contact-making surface with push pedal 7 applyings and becomes 90 degree angles with the mould die joint that dynamic model 5 and cover half 4 applyings constitute.
Good for the shaping that makes foundry goods, deflection is little, yield rate is high, key is to control the slide block 3 drawing-die distortion of mould.For this reason, the utility model adopts Planar Fractal, on slide block 3, be provided with the slide block post rod mechanism, during die sinking, push rod 2 when slide block 3 moves in the slide block post rod mechanism withstands die casting 1, has so just avoided foundry goods 1 with the trend that slide block 3 walks toward outside, and it is rested on the mold cavity, guarantee its dimensional stability, prevent to draw distortion.The final size that the utility model can rationally be controlled die casting changes, thereby reduces the die casting defective, improves the production qualification rate of die casting, reduces production costs.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
