Shape step.
Further, the clinch of the multiple lug and the lower end of the junction of the fixed part are provided with ventilation
Groove.
Further, the clinch of a lug in the multiple lug is provided with two fabrication holes, remaining lug
Clinch is provided with a fabrication hole.
Further, multiple mounting grooves are evenly distributed with the side of the positioning bed die.
Further, multiple mounting holes are evenly distributed with the side of the positioning bed die.
Further, the positioning bed die is circle.
Further, the lug is three.
Relative to prior art, outer formula core fixed structure of taking of the present utility model is by setting positioning bed die and multiple taking
Son, is fixed core using multiple lugs, has both solved the problems, such as that single-contact is unstable during core fixation in the prior art, again
Avoiding core heated gas and being difficult to discharge makes product produce stomata, improves the production quality of product.It is of the present utility model outer
Taking formula core fixed structure has the advantages that simple in construction, stability is good, venting quality is good.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.

Refer to Fig. 1 and Fig. 2, it is of the present utility model it is outer take formula core fixed structure, including positioning bed die 10 and multiple take
Son 20, the multiple uniform ring of lug 20 are located on the positioning bed die 10；The multiple lug 20 includes the He of fixed part 21
Clinch 22, the fixed part 21 are fixed on the positioning bed die 10, and the clinch 22 is in inverted concave shape, described to take
The side of socket part 22 is connected with the fixed part 21, the opposite side of the clinch 22 towards the middle part of the positioning bed die 10,
And it is provided with gap between the bottom of the clinch 22 and the positioning bed die 10.
The middle part of the positioning bed die 10 of the present embodiment is provided with casting hole 11, and the positioning bed die 10 is in the multiple
The bearing of the fixed part 21 of lug 20 is provided with intilted ring-shaped step 12.
The locating slot 13 being used for as the positioning of multiple lugs 20 that multiple uniform rings are set, institute are provided with the positioning bed die 10
The side that locating slot 13 is communicated to the positioning mould is stated, in casting, locating slot 13 can play a part of exhaust, prevent product
Stomata is produced, solves the exhausting problem of existing structure, and the exhaust main of core will be realized by way of negative pressure ventilation.This implementation
Example is provided with three locating slots 13, and the angle of three locating slots 13 between any two is 120 degree.
