Abstract
The utility model discloses a kind of center casting mould that is used for horizontal plunger die casting machine, being provided with up and down four between the fixed half and moving half looses core, sprue bush is set on the cover half, core is set on the dynamic model, the center of described core is corresponding with the center of sprue bush, behind the end matched moulds of core in sprue bush and and sprue bush between leave space as running channel, this running channel is communicated with the shape chamber by the ingate of sprue bush end.The utility model is simple in structure, and the mould manufacturing is simplified, and can improve product yield, reduces production costs.
Description
Technical field
The utility model relates to a kind of die casting, particularly a kind of center casting mould that is used for horizontal plunger die casting machine.
Background technology
At present, motorcycle engine cylinder body die casting normally adopts vertical die-casting machine die casting, because the die casting producer that has also adopts horizontal plunger die casting machine die casting because there is not vertical die-casting machine.Adopt horizontal plunger die casting machine die casting motorcycle this class die casting of engine cylinder block, the structure of its die casting is to be provided with up and down four between the fixed half and moving half to loose core, core is arranged on the cover half, at cover half and the contact jaw of loosing core, the circulation running channel that the geometric pattern core is provided with " U " shape forms the encircling type running gate system with four ingates on loosing core up and down, the cast gate of running gate system is eccentrically set on the cover half, eccentric cast gate is communicated with the circulation running channel by a crossing current running channel, the sprue bush of eccentric cast gate is installed on the cover half, the branch flow cone is located to loose core under the dynamic model to go up and is inserted in the sprue bush, and sprue bush presses the chamber to be communicated with casting.The compression mod of this kind structure is because the running gate system complexity, cast aluminum liquid is by pressing the chamber to enter sprue bush, after minute flow cone shunting, enter the shape chamber from ingate by crossing current running channel, circulation running channel, because of its running channel longer, it is more that mould material remains in running channel, the material cake is big, causes the foundry goods yield rate low, is about 50%～65%; Owing to need to make complicated running channel and the branch flow cone is set on sliding block, cause the mould manufacture difficulty big; And crossing current running channel place causes potting syrup to overflow to make down the slide block clamping stagnation of loosing core, cause production discontinuous, influence manufacturing schedule easily.
Summary of the invention
The purpose of this utility model provides a kind of center casting mould that is used for horizontal plunger die casting machine, and it has simplified running channel, and it is simple to have a mould manufacturing, the characteristics that product yield improves.
The purpose of this utility model is achieved in that being provided with up and down four between the fixed half and moving half looses core, sprue bush is set on the cover half, core is set on the dynamic model, the center of described core is corresponding with the center of sprue bush, behind the end matched moulds of core in sprue bush and and sprue bush between leave space as running channel, this running channel is communicated with the shape chamber by the ingate of sprue bush end.
The end of described core is provided with the conical surface.
One end of the corresponding core of described sprue bush is made as taper hole, and the space between the conical surface of its taper hole and core end is a running channel.
Owing to adopted such scheme, being used for being provided with between the fixed half and moving half of mould of horizontal plunger die casting machine up and down four looses core, sprue bush is set on the cover half, core is set on the dynamic model, the center of described core is corresponding with the center of sprue bush, behind the end matched moulds of core in sprue bush and and sprue bush between leave space as running channel, this running channel is communicated with the shape chamber by the ingate of sprue bush end.Because of core is arranged on the dynamic model, sprue bush can be arranged on the cover half by corresponding core, the casting of formation center.The end of described core is provided with the conical surface, one end of the corresponding core of described sprue bush is made as taper hole, space between the conical surface of core end and the sprue bush taper hole is a running channel, potting syrup directly enters the shape chamber by the core shunting by ingate in sprue bush, shortened the distance of running channel, make the mould material that remains in the running channel few, the material cake is little, and the product yield of foundry goods is brought up to more than 80%.This structure has been saved circulation running channel and crossing current running channel has been set on cover half, saved under labyrinth such as branch flow cone is set on loosing core, simplified the manufacturing of mould, reduced the manufacturing cost of mould.And because of its saved circulation running channel on the cover half and crossing current running channel and loose core down on the branch flow cone, the joint close of mould significantly reduces, potting syrup overflows the phenomenon of the slide block clamping stagnation of loosing core almost can be avoided, and assurance equipment can be produced continuously, has improved production efficiency.
The utility model is simple in structure, and the mould manufacturing is simplified, and can improve product yield.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Referring to Fig. 1, Fig. 2, be provided with up and down four between cover half 3 and the dynamic model 1 and loose core 2,8,10,11, loose core and can on dynamic model 1, slide.Sprue bush 6 is set on the cover half 3, and sprue bush is embedded on the cover half, adopts interference fit or excessive cooperation all can reach same effect.Core 9 is set on the dynamic model 1, and core is embedded on the dynamic model, adopts interference fit or excessive cooperation all can reach same effect.The center of described core 9 is corresponding with the center of sprue bush 6, behind the matched moulds by dynamic model 1, four loose core 2,8,10,11 and core 9 constitute foundry goods shape chamber.Behind the end matched moulds of described core 9 and sprue bush 6 corresponding ends in sprue bush 6 and and sprue bush between leave space as running channel 5.The end of described core 9 is provided with the conical surface, and an end of described sprue bush 6 corresponding cores 9 is made as taper hole, and the space between the conical surface of its taper hole and core end is a running channel 5, and this running channel 5 is communicated with the shape chamber by the ingate 4 of sprue bush end.
During installation, dynamic model 1 and cover half 3 are separately fixed on the horizontal type die-casting machine equipment, and sprue bush 6 is fitted with the pressure chamber of horizontal plunger die casting machine, makes the drift of die casting machine can enter sprue bush.Sprue bush is good with the diameter of bore of the drift section of cooperation less than foundry goods diameter of bore effect.
With die casting motorcycle engine cylinder block on horizontal plunger die casting machine is example, and the diameter of bore of sprue bush 6 and the drift section of cooperation is less than cylinder block cylinder bore dia, by dynamic model 1, four loose core 2,8,10,11 and core 9 matched moulds after constitute cylinder bodily form chamber.Aluminium liquid enters shape chamber from running channel 5 through ingate 4 by the shunting of core 9 ends in sprue bush 6 under the pressure of drift, the cooling aftershaping, and residual aluminium forms small powder cake 7 in running channel 5 and sprue bush 6.During die sinking, moulding cylinder block castings and material cake 7 move with dynamic model 1, open up and down four and loose core, and eject cylinder block castings, remove the material cake 7 that is connected on the foundry goods, promptly finish a casting process.
