Abstract
The utility model discloses a mold for casting a gearbox shell. The mold comprises a fixed mold, a moving mold and a mold splitting driving device. The fixed mold and the moving mold are assembled to form a casting mold cavity, the mold splitting driving device is arranged below the fixed mold and provided with a plurality of first ejector rods used for jacking up the moving mold in order to separate the moving mold from the fixed mold, an ejection mechanism is arranged at the position, corresponding to the position where a casting is prone to deformation, of the fixed mold, the ejection mechanism is arranged at the bottom of the fixed mold, and a draft inclination angle, corresponding to the position where the casting deforms, of the fixed mold and/or the moving mold is opposite to the deformation direction of the casting. The ejection mechanism has a good improvement effect on deformation of the casting of the gearbox shell due to enclasping force; the demolding angle is changed, so that deformation is effectively reduced, the defective rate of the casting is further reduced, and production efficiency is improved; the mold is simple in structure and easy to obtain and popularize.
Description
Technical field
The utility model relates to casting technology field, relates in particular to a kind ofly for casting the mould of gear box casing, and this mould can improve the deformation defect of gearbox in when casting.
Background technology
Die-Casting Industry is one of important support industry of auto industry, and developing rapidly of car industry in recent years adds and the development trend of automotive light weight technology driven the sharply excessive of Die Casting Market.Progressively shift to China at die casting industry center at present, and domestic aluminium Die Casting Industry has vast potential for future development.
For automatic transmission casing, its general founding materials adopting is aluminium alloy ingots (ADC12), and mold materials is domestic H13 steel, and the die casting equipment adopting is 1600T cold-chamber die casting machine, and whole press casting procedure is full-automatic technique.But in casting process, because Design of Dies is unreasonable, the product of casting is easy to occur local deformation, and defective products rate, substantially in 15% left and right, has not only had a strong impact on casting quality and production efficiency, also wasted more processing cost simultaneously.
In view of above-mentioned defect, be necessary in fact to design a kind of novel for casting the mould of gear box casing.
Utility model content
Technical problem to be solved in the utility model is: existing for the mould of casting gear box casing because structural design is unreasonable, demoulding ability is poor, easily make foundry goods produce distortion, and then have a strong impact on casting quality and production efficiency, and processing cost is higher.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of for casting the mould of gear box casing, it comprises cover half, dynamic model and parting drive unit, described cover half and described dynamic model matched moulds form foundry goods die cavity, described parting drive unit is arranged on described cover half below, described parting drive unit be provided with some for by described dynamic model jack-up with first push rod separated with described cover half, described cover half is provided with ejecting mechanism corresponding to the yielding position of described foundry goods, described ejecting mechanism is arranged on described cover half bottom, and the withdrawing pattern inclination angle of the yielding position of the corresponding described foundry goods of described cover half and/or described dynamic model and the deformation opposite direction of described foundry goods.
Described ejecting mechanism comprises the push pedal corresponding with the yielding position of described foundry goods further; The resilient key fixed head of described foundry goods one side dorsad that is arranged on described push pedal, described resilient key fixed head is provided with fixed head screw, resilient key and spring; And one end is fixedly attached in push pedal, the other end is through the push rod and the release link that are connected with described ejecting mechanism after described resilient key fixed head.
Described ejecting mechanism is described parting drive unit further.
Further described dynamic model and/or described cover half be provided with slide block with corresponding position, the yielding position of described foundry goods, described slide block is against described foundry goods body.
Adopt technique scheme, the utility model at least comprises following beneficial effect:
The utility model, by increasing ejecting mechanism in the yielding position of foundry goods, has the good effect of improving to foundry goods because enclasping force is out of shape; In addition, by changing demoulding angle, and then can change the deformation direction of foundry goods, and slide block is set herein, and make slide block compress foundry goods, make foundry goods be subject to the resistance that deformation direction is contrary, effectively stop casting deformation, therefore described in the utility modelly for casting the mould of gear box casing, can make the deflection of foundry goods obviously reduce, reduced product fraction defective, reduce production costs, enhance productivity simultaneously.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figures 1 to 4, of the present utility model a kind of for casting the mould of gear box casing for meeting, it comprises dynamic model 1, cover half 2 and parting drive unit, described parting drive unit is for separated or closed with described cover half 2 by described dynamic model 1, described cover half 2 and described dynamic model 1 matched moulds form foundry goods die cavity, described parting drive unit is arranged on described cover half 1 below, described parting drive unit be provided with some for by described dynamic model 1 jack-up with the first push rod with described cover half 2 partings, described cover half 2 corresponding to the yielding position of described foundry goods, be provided with ejecting mechanism 3, described ejecting mechanism 3 is arranged on the bottom of described cover half 2, the withdrawing pattern inclination angle of the yielding position of the corresponding described foundry goods of described cover half 2 and the deformation opposite direction of described foundry goods.Certainly, described withdrawing pattern inclination angle also can be arranged on dynamic model 1, or is provided with withdrawing pattern inclination angle on dynamic model 1 and cover half 2, and those skilled in the art can set completely according to actual needs voluntarily, and the present embodiment is not construed as limiting this.Yielding position described in the present embodiment is determined by the concrete structure of gear box casing simultaneously, belongs to those skilled in the art's general knowledge, repeats no more herein.
In the present embodiment, described ejecting mechanism 3 comprises the push pedal 31 corresponding with the yielding position of described foundry goods; The resilient key fixed head 32 of described foundry goods one side dorsad that is arranged on described push pedal 31, described resilient key fixed head 32 is provided with fixed head screw 33, resilient key 35 and spring 34; And one end is fixedly attached in push pedal, push rod and release link that the other end is connected with described ejecting mechanism 3 after through described resilient key fixed head 32.
