Abstract
A kind of core box, comprise core box, lower core box, arbor, upper core box is provided with upper impression, and lower core box is provided with lower impressions, and after upper core box and lower core box matched moulds, upper impression and lower impressions form the forming cavity of core, and arbor is placed in the middle part of forming cavity.When production simple shape core, be provided with locating slot inside upper core box, lower core box contact surface, arbor two ends are loaded on locating slot place.When core shape is more complicated or be not easy to arbor expose time, lower core box inwall is equipped with one with upper supporting piece, and arbor is placed on support member.The utility model can prevent precoated sand core shooting from manufacturing and core distortion in core use procedure, has that structure is simple, easy to operate, reliability is high, raising product percent of pass, the advantage of increasing economic efficiency.
Description
Technical field
The utility model relates to a kind of core box, belongs to casting technique field.
Background technology
At present, in aluminium alloy tubing castings production process, precoated sand is with its good surface smoothness and precision and good thermal runaway, and cheap cost becomes aluminium alloy tubing core cavity core preferred material.According to core cavity structure and size, the long narrow lumens core mode of production is fabricated to master with core shooting.But due to the restriction of tubing casting structure, its Shortcomings part is: one is tubing core cavity slender construction, and core is in making and deposit in process and easily produce distortion, affects Product Precision, even causes waste product; Two is the limited strength of core material own, in transport and use procedure, is subject to External Force Acting fracture, causes core itself to be scrapped.Be out of shape for preventing this type of core or damage, a lot of company adopts forming frock to deposit core, and its weak point is: one is that forming frock makes complexity, and production cost is high; Two is forming frock poor universality, and along with product category change, original frock certainly will be transformed or scrap, and causes damage; Three is that forming frock effectively can not prevent core self deformation of creep.
Summary of the invention
The purpose of this utility model is to overcome precoated sand core-shooting sand core above shortcomings in manufacture and use procedure, and provides the core box of a kind of anti-deformation with low cost, simple to operate and raising sand core strength.
Technical solutions of the utility model are: comprise core box, lower core box, arbor, upper core box is provided with upper impression, and lower core box is provided with lower impressions, and after upper core box and lower core box matched moulds, upper impression and lower impressions form the forming cavity of core, and arbor is placed in the middle part of forming cavity.
Be provided with locating slot inside described upper core box, lower core box contact surface, arbor two ends are loaded on locating slot place.
Described lower core box inwall is equipped with one with upper supporting piece, and arbor is placed on support member.
Described support member has mounting groove.
Described arbor is cylindrical, and mounting groove is semi-circular recesses, and semi-circular recesses plays and prevents from penetrating sand and the core box open and close movement SMIS position of bone moves effect.
Core box presets arbor processing support part, and simple shape core can be set directly at core print position, and core shape is more complicated or be not easy to arbor when exposing, and can need strengthen intensity locations increase processing support part at core box inner chamber core.When using the utility model, prefabricated arbor is placed in support member semi-circular recesses, places steadily and can penetrate sand by matched moulds.After core completes, because core is strengthened with arbor, arbor intensity is far longer than core itself, can effectively prevent core to be out of shape and external force resistance ability.During casting cleaning, along with core is cleaned, arbor is taken out by sand export and collects, during for coremaking next time.The letter of the utility model materials economizes, easy to operate, reliability is high, greatly improves the qualification rate of core.

Fig. 1 is one of structural representation of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Fig. 3 is the sectional view of Fig. 2.
Detailed description of the invention
In Fig. 1, the utility model comprises core box 1, lower core box 4, arbor 2, and upper core box 1 is provided with upper impression, and lower core box 4 is provided with lower impressions, after upper core box 1 and lower core box 4 matched moulds, upper impression and lower impressions form the forming cavity of core, and arbor 2 is placed in the middle part of forming cavity.Be provided with locating slot inside upper core box 1, lower core box 4 contact surface, arbor 2 two ends are loaded on locating slot place.Use the core 3 that the utility model is produced, because arbor 2 exposes outside core 3 core print, need to increase on upper core box 1, lower core box 4 to allow bit space and locating slot, interfere to prevent arbor and mould.Arbor is shaping 6-10mm reinforcing bar.
In Fig. 2,3, the utility model comprises core box 1, lower core box 4, arbor 2, and upper core box 1 is provided with upper impression, and lower core box 4 is provided with lower impressions, after upper core box 1 and lower core box 4 matched moulds, upper impression and lower impressions form the forming cavity of core, and arbor 2 is placed in the middle part of forming cavity.Lower core box 4 inwall is provided with a support member 5, and arbor 2 is placed on support member 5.
During production, before matched moulds, arbor 2 is arranged on processing support part 5 default on lower core box, and the core box 1 that then closes can carry out normal core making.After core 3 has solidified, arbor 2 together takes out with core 3 and leaves on general tool for transmitting.Complex-shaped structure core or be not easy to arbor expose time, the utility model is used to produce core 3, because processing support part is formed with fabrication hole on core 3 body, core needs before using by means such as white claies fabrication hole to be closed and repaired to flush with core 3 outer surface.The core using the utility model to produce, because high strength, high rigidity arbor 2 are present in core 3 all the time, greatly strengthen the resistance to deformation of core 3, resistant to breakage ability, reduces damage and the disqualification rate of core.During casting cleaning, arbor 2, because diameter is much smaller than sand export size, can takes out easily when sand removal and collect and use for during next coremaking.The utility model auxiliary material used can be reused, and improves product percent of pass, increases economic efficiency.
