Formula core fixed structure is taken outside a kind of
Technical field
Motor casing manufacture mould applications are the utility model is related to, formula core fixed structure is taken outside more particularly to one kind.
Background technology
Core is the material for being used to manufacture core in Foundry Production, typically by casting model powder, moulding sand binder and additional thing etc. Modeling Material is made by mixing forms according to a certain percentage.Core needs to be fixed on mould in casting, and core fixes one It is directly the technical barrier for perplexing engineer.
At present, many cores are mainly fixed by single-point and contacting dies, and the mode of single-contact causes consolidating for core Fixed unstable, easily therefore core rocks, and causes to produce gap between core and product, and then influences production quality;Separately Outside, gas is also easy to produce because core is heated, if can not discharge gas from core in time, easily produces gas in the product Hole, influence product quality.
Therefore, in the market has increasing need for a kind of to consolidate core fixing-stable and the core that can discharge gas in time Determine structure.
Utility model content
Based on this, the purpose of this utility model is, there is provided takes formula core fixed structure outside a kind of, it has structure simple Singly, the advantages of stability is good, venting quality is good.
Formula core fixed structure is taken outside a kind of, including positioning bed die and multiple lugs, the multiple lug uniform ring are located at On the positioning bed die;The multiple lug includes fixed part and clinch, and the fixed part is fixed on the positioning bed die On, the clinch is in inverted concave shape, and the side of the clinch is connected with the fixed part, the clinch it is another Side is provided with gap towards the middle part of the positioning bed die between the bottom of the clinch and the positioning bed die.
Outer formula core fixed structure of taking of the present utility model utilizes multiple lugs by setting positioning bed die and multiple lugs Core is fixed, has both solved the problems, such as that single-contact is unstable during core fixation in the prior art, turn avoid core and is heated Gas, which is difficult to discharge, makes product produce stomata, improves the production quality of product.
Further, it is provided with casting hole in the middle part of the positioning bed die.
Further, the positioning being used for as the positioning of multiple lugs that multiple uniform rings are set is provided with the positioning bed die Groove, the locating slot are communicated to the side of the positioning mould.
Further, the bearing of fixed part of the positioning bed die in the multiple lug is provided with intilted ring 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.
Brief description of the drawings
Fig. 1 is the outer structural representation for taking formula core fixed structure of the present utility model.
Fig. 2 is the outer top view for taking formula core fixed structure of the present utility model.
Fig. 3 is the structural representation of multiple lugs.
Embodiment
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.
The positioning bed die 10 of the present embodiment is circle.Multiple peaces are evenly distributed with the side of the positioning bed die 10 Tankage 14 and multiple mounting holes 15.
Referring to Fig. 3, the intermediate space size of the concave shape clinch 22 of the multiple lug 20 can be according to the thickness of core Degree is set.
The clinch 22 of the multiple lug 20 of the present embodiment and the lower end of the junction of the fixed part 21 are respectively provided with There is air channel 23.
The clinch 22 of a lug 20 in the multiple lug 20 is provided with two fabrication holes 221, remaining lug 20 Clinch 22 be provided with a fabrication hole 221.The lug 20 of the present embodiment is three, and three lugs 20 are between any two Angle is 120 degree, and three lugs 20 solve the problems, such as that core single-contact is unstable.One in three lugs 20 is taken The clinch 22 of son 20 is provided with two fabrication holes 221, and the clinch 22 of other two lug 20 is provided with a fabrication hole 221, in casting, can practical stainless steel 304 bowl-type plug as closure, realize the sealing of product.
The outer application method for taking formula core fixed structure of the present utility model:
First, the preparation of core can be using mound roughing sand as raw material, and realistic scale core shooter is at a temperature of 280 DEG C Solidification 150 seconds, you can obtain core moulding.
The clinch 22 of three lugs 20 is socketed on core, and the fixed part 21 of three lugs 20 is separately fixed at On three locating slots 13 for positioning bed die 10.
