Description
Technical field
The utility model relates to a kind of automobile engine cylinder die casting.
Background technology
A automobile engine cylinder that die casting at present is good is follow-up also will just to carry out the assembling of whole engine through the multiple tracks finishing step.Show as Fig. 1, in the actual production, during locating hole 201 on fine finishining cylinder 2 one side locating platforms 21, find that these platform 21 inner sbrinkage blowholes are more, this is the fine and close inadequately performances of cylinder 2 foundry goods internal structures, and tracing it to its cause is because the boss 31 on the mould left slider 3 of this side platform 21 of die cast, as shown in Figure 2, can't further push, cause the foundry goods interior solid relatively poor foundry goods.Just can avoid above-mentioned defective if can in the process of die casting cylinder side locating platform 21, realize precast hole simultaneously.
Summary of the invention
The utility model purpose is: a kind of automobile engine cylinder die casting that can realize precast hole in the process of die casting cylinder is provided, can improves the compactness at cylinder blowhole position greatly, improve product quality.
The technical solution of the utility model is: a kind of automobile engine cylinder die casting comprises being located at being used for the left slider of forming cylinder foundry goods one side concave surface on the die casting machine that the press casting surface of this left slider is provided with the boss that is used for this side locating platform of forming cylinder; Precast hole mechanism also is installed on the left slider, and this precast hole mechanism comprises the push rod of loosing core, drive rod and driving mechanism, and described driving mechanism is fixed on the left slider; Described drive rod connects driving mechanism and is moved forward and backward by its driving; The described push rod of loosing core places in the perforate on the boss, and this push rod of loosing core is provided with skewed slot or skewback, and drive rod is provided with skewback or the skewed slot that cooperates with it, and drives the push rod of loosing core with this and move up and down along perforate.
The mechanism of precast hole described in the utility model also comprises two capable bit switches that are fixed on the driving mechanism, and they all are electrically connected with control device on the die casting machine.
The quantity of skewed slot on the push rod or skewback loose core described in the utility model preferably more than one, and they be arranged in parallel each other; Accordingly, drive rod be provided with the push rod of loosing core on skewed slot or the skewback of the corresponding one by one coupling of skewback or skewed slot between also be arranged in parallel.
Driving mechanism described in the utility model can be selected hydraulic cylinder of the prior art, perhaps cylinder, perhaps linear electric motors.
This automobile engine cylinder die casting described in the utility model, its complete structure is the same with prior art, except left slider, also comprises the right slide block, top shoe, sliding block, the fixed half and moving half that are installed on the die casting machine.Described cover half, dynamic model, left slider, right slide block, top shoe, sliding block have been formed the die cavity of cylinder foundry goods jointly, and the inner chamber of cylinder foundry goods is by moving, the together moulding of cover half core, the spark plug chamber is by the cover half core moulding, four side concave surfaces of cylinder foundry goods are then by four sides slide block moulding, and the cover half core passes through the inclined-plane driving fit with the four sides slide block.
When the utility model carried out die casting, the four sides slide block closed up at the center in the same way by two Driven by Hydraulic Cylinder one separately, with four side concave surfaces of forming cylinder foundry goods; Wherein the boss on the left slider press casting surface is used for this side locating platform of forming cylinder; After left slider advanced to assigned address, makes the first one-step forming of locating platform, the control device in the die casting machine sent signal immediately and makes the running of precast hole mechanism.So this precast hole mechanism travels forward by the driving mechanisms control drive rod, drive the push rod of loosing core by drive rod again and upwards eject along the perforate on the boss, on locating platform, punch.When moving to assigned address, drive rod makes after the locating hole moulding on the locating platform, two capable bit switches pass to control device in the die casting machine with the position signalling of drive rod this moment, order about control device and send the withdrawal of control signal control drive rod immediately, and then order about the push rod of loosing core and descend and detach locating hole on the locating platform.When drive rod was retracted to assigned address, two behavior switches sent signal once more and give control device, drove four sides slide block rollback together, finished die casting.
The utility model advantage is:
This automobile engine cylinder die casting described in the utility model, because precast hole mechanism has been installed on left slider, so can in moulding cylinder one side concave surface locating platform, be implemented in the purpose of blowhole on it, save the fine finishining drilling operating of back, simplified production stage, save the production time, improved production efficiency.And because the utility model is when blowhole, the push rod of loosing core ejects casting material, and this part material is squeezed to all around to reinforce foundry goods by force by left slider simultaneously, so improved the compactness of cylinder block inside greatly, reduced sbrinkage blowhole quantity, improved product quality greatly.
