Die casting and utilize it to produce the method for washing machine tripod
Technical field
The present invention relates to the production of washing machine tripod, particularly a kind of die casting and utilize it to produce the method for washing machine tripod.
Background technology
Along with the fast development of whole electrical apparatus industry, drive progress and the lifting of household electrical appliances manufacturing enterprise technology of doing washing, in the face of the keen competition of international household electric appliances, force the requirement that internationally famous household appliances enterprise proposes more, higher standard to washing machine and reduces costs.And tripod is as the main components of washing machine, to its service life and Structural strength calls high.The international esbablished corporation such as Siemens is for guaranteeing product quality, and even do not stint and introduce described product from external for a long time, not only cost is high, and the friendship phase cannot ensure.
Existing each manufacturer is all the die casting in mould one cave for the production of the mould of washing machine tripod usually, each die casting can only produce a washing machine tripod product, cause that production efficiency cannot improve, production cost is difficult to reduce, if and need the production method of accomplishing mould two cave, especially crucial to the design of the design of the running channel of mould and air discharge duct, directly have influence on the requirement whether the washing machine tripod quality utilizing the mould in this kind mould two cave to produce meets structural strength, existing each producer can not meet again such mould of quality requirement.
In addition, the auto-processes degree of current each manufacturer production washing machine tripod is low, production efficiency is low, and some production stages still adopt manual work, and precision and crudy are difficult to ensure.
Summary of the invention
The technical problem to be solved in the present invention is that the mould production efficiency in mould one cave for the production of washing machine tripod in order to overcome prior art is low, the undesirable defect of Mould Machining quality in mould two cave, provides a kind of die casting and utilizes it to produce the method for washing machine tripod.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of die casting, for the production of washing machine tripod, its feature is, described die casting comprises a dynamic model, a cover half, two groups of cores, forms the die cavity that two are arranged symmetrically in the center line both sides of described dynamic model after described dynamic model and described cover half matched moulds;

The center of described dynamic model is provided with the running channel that a shunting is chewed, two symmetrical, one end of running channel described in each bar is the section of confluxing, the other end of each described running channel is four shunting sections, the described section of confluxing is positioned at the side that described shunting is chewed, and four described shunting sections are all connected with described First Transition portion and are uniformly distributed between 1/4th position to four/tri-positions of arc length in described First Transition portion;
Three leg cinder ladles are all evenly equipped with on the top end face of described first foot section, on the top end face of described second foot section and on the top end face of described 3rd foot section, the center of described second transition part and the center of described 3rd transition part are equipped with a center cinder ladle, on described second transition part and on described 3rd transition part and the middle section position place being all positioned at described 3rd foot section is equipped with a stage casing cinder ladle, each described leg cinder ladle, each described center cinder ladle and each described stage casing cinder ladle be a corresponding cinder ladle air discharge duct leading to the edge of described dynamic model all separately;
Often organize described core group and comprise the core of center, end that three are arranged in the center, end of described first foot section, the center, end of described second foot section and described 3rd foot section respectively.
Preferably, each described running channel also comprise two tributary sections, the section of confluxing described in one end of each described tributary section connects, the other end of each described tributary section connects two described shunting sections.Thus when die casting, make molten metal energy evenly speed flow to each shunting section, then flow in each described die cavity.
Preferably, described on the top end face of the first foot section described in two be close to mutually two, the shape of leg cinder ladle is trapezoidal, described on the top end face of the second foot section described in two be close to mutually two, the shape of leg cinder ladle is trapezoidal, and the shape of leg cinder ladle described in remaining is all rectangular.Thus make the more compact structure described in two between die cavity, reduce the volume of described die casting.
Produce a method for washing machine tripod, its feature is, it comprises the following steps:
Step one, automatic spraying machine is utilized to spray mould release on the inwall of the die cavity of die casting as above;
Step 2, by streamline, some inserts are delivered to workbench, and with manipulator described inserts are mounted on the described central part in each described die cavity of described die casting;
Step 3, described die casting is utilized to carry out die casting manufacture, obtained some washing machine tripod shape embryos, wherein, each washing machine tripod shape embryo comprises two washing machine tripods, at the connecting portion described in two between washing machine tripod, some cinder ladles be looped around around described two washing machine tripods;
Step 4, to utilize manipulator that each described washing machine tripod shape embryo is moved to the enterprising sector-style of cold air rack but cold;
Step 5, automatic punching machine punching press is utilized to excise described connecting portion on each described washing machine tripod and described cinder ladle;
Step 6, to case for each described washing machine tripod preservation.
In the present invention, above-mentioned optimum condition can be combined on the basis meeting this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: die casting of the present invention and the research and development success utilizing it to produce the method for washing machine tripod not only greatly reduce production cost, improve production efficiency, achieve and produce two high-quality washing machine tripods by the die casting in mould two cave of the present invention is disposable, and achieve automated production, instead of manual installation inserts originally, manual pickup, improve the cooling of washing machine tripod shape embryo, present air-cooled cooling is become from original cooling naturally, thus make client turn to domestic procurement from the plan of external buying, not only quality assurance, the friendship phase ensures, on cost, income is high especially, greatly reduce the purchase cost of manufacturer's assembling finished product.
