Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
Refering to fig. 1-11, be a kind of structure of cast die described in the utility model, including set gradually front template 1,
First rear pattern plate 2, the second rear pattern plate 3, the first ejector retainner plate 4, the second ejector retainner plate 5 and bottom plate 6, the front template and the first rear pattern plate
Between be equipped with the first mode for shaped article, for deslagging is equipped between first rear pattern plate and the second rear pattern plate
Two modes；First ejector retainner plate is equipped with the first thimble 41, and the first thimble activity passes through second rear pattern plate and prolongs
On the first mode for extending to first rear pattern plate, oil cylinder 7 is fixed on second rear pattern plate, the oil cylinder is able to drive institute
State the first ejector retainner plate move forward and backward with will take shape in first mode product ejection；Second ejector retainner plate and described the
One rear pattern plate is fixedly connected, and second ejector retainner plate is equipped with the second thimble 51, and the second thimble activity passes through described first
Ejector retainner plate simultaneously extends to the second rear cavity on second rear pattern plate, and die casting machine mandril 8 is fixed on described across the bottom plate
On second ejector retainner plate, the die casting machine mandril is able to drive second ejector retainner plate and is moved forward and backward with will be in second mode
Paint slag ejection.
Wherein, the quadrangle of first ejector retainner plate is respectively equipped with back stitching 42, after the back stitching is actively located in described second
In template 3 and the first rear pattern plate 2.The quadrangle of second rear pattern plate is respectively equipped with guide post 31, and the guide post is actively located in institute
It states in the first rear pattern plate.Second ejector retainner plate is fixedly connected with first rear pattern plate by connecting rod 9.
Pin 10 is fixed at second thimble position in addition, corresponding on the bottom plate, on second ejector retainner plate
The second centre hole 52 be three-stage: the first segment radius of the second centre hole is identical as the radius of the pin, the second centre hole
Second segment radius it is identical as the heavy head radius of second thimble, the third section radius of the second centre hole and it is described second top
The thimble radius of needle is identical, and the length of the second segment of second centre hole is greater than the length in the countersunk head portion of second thimble
Degree；When second ejector retainner plate does not eject state, the first segment that the end activity of the pin passes through second centre hole prolongs
It extends in the second segment of the second centre hole and overhead is on the outer end face in the countersunk head portion of second thimble.
The workflow of the structure of cast die is as follows:
The first step, die sinking: refering to Fig. 4, die casting machine drives the first rear pattern plate 2, the second rear pattern plate 3, the first ejector retainner plate 4, the
Two ejector retainner plates 5 and bottom plate 6 move out together to be separated with front template 1, realizes die sinking.
Second step, the first ejector retainner plate ejecting product: refering to Fig. 5, oil cylinder 7 drives the first ejector retainner plate 4 to travel forward, the first top
The first thimble 41 on needle plate 4 ejects the product 11 in the first mode for taking shape in the first rear pattern plate 2.
Third step, the first thimble sheet reset take out product: refering to Fig. 6, oil cylinder 7 drives the first ejector retainner plate 4 to move back backward
Product 11 is taken out in position.
4th step, the second ejector retainner plate eject deslagging (using delayed ejection): refering to Fig. 7-9, die casting machine mandril ejection second
When ejector retainner plate 5, the second ejector retainner plate first travels forward a trip, and the second thimble is big due to the second segment length of the second centre hole
In the heavy head length of the second thimble, therefore when the second ejector retainner plate starts to travel forward, the second thimble is motionless, until the second thimble
Countersunk head portion behind the first segment end to the second centre hole, the second thimble just travel forward with the second ejector retainner plate, when
When second thimble is moved forward in the second template with the second ejector retainner plate, since the first template and the second ejector retainner plate are fixed together simultaneously
It travels forward with the second ejector retainner plate, so that the second thimble ejects the paint slag in the second mode, realizes deslagging function.
5th step, the second thimble sheet reset: refering to fig. 10, the effect of the second ejector retainner plate and the first template in die casting machine mandril
Lower return.
6th step, molding: refering to fig. 11, die casting machine drives the first rear pattern plate 2, the second rear pattern plate 3, the first ejector retainner plate 4, the
Inwardly movement and front template 1 mold together for two ejector retainner plates 5 and bottom plate 6, complete primary production molding.
The die casting is used for deslagging due to being provided with two templates and two modes, the second rear cavity, can be by column position
Internal air is effectively discharged, and extra cold burden can be emptied, and effectively solves the problems, such as that product fills bad, raising
Die-cast product quality.
It can be seen that the cast die, which changes two traditional formwork structures, is designed as three formwork structures, a template
For the molding of product, i.e. material position, another template is used for deslagging and ejection, thus solve product column position it is higher more when,
Product fills bad problem, improves the quality of die-cast product.In addition, the structure of cast die is also provided with delayed ejection knot
Structure prevents thimble stress is excessive from thimble bending or broken needle phenomenon occur, improves thimble service life and product quality.
