Abstract
The invention proposes a device for once blow molding of sand cores and chillers. The device comprises two half molds symmetrically arranged and respectively being a left half mold and a right half mold, wherein inserts are arranged on the half molds; three copper sleeves are arranged on the inserts; magnets are arranged in the copper sleeves; two heating pipes are arranged at one sides of the inserts; semicircular chillers are arranged at the other sides of the inserts, and are absorbed in the half molds through the magnets; molding cavity sand cores are arranged in the semicircular chillers; three exhaust connecting holes are formed in the molding cavity sand cores; and a sand ejecting port is formed above the joined place of the two half molds. The device can realize once blow molding of the sand cores and the chillers; the manufactured sand cores and chillers are smooth and tidy in joint, and need no repair and baking; and the sand cores blown by the device save multiple production procedures, guarantee the product size requirement, and improve the inherent and appearance qualities of castings.
Description
Technical field
The present invention relates to a kind of device for core and a chill blow molding.
Background technology
Blow in prior art in core and Chill and often there will be following problem:
1, the method adhered to after common blowing core and the multiplex first coremaking of Chill, the chill of adhesion is uneven (having a strong impact on product size), gas forming amount large, also needs to repair gap, and also need baking afterwards, operation is many, and labour intensity is large, and cost is high.
2, in common blowing core and Chill also have and be first placed in by various method, one-time formed method, but often exist chill up and down, the problem of left and right sidesing shifting, poor effect.
3, common blowing core and Chill are to having curved surface and the large chill of area almost cannot be made.
Summary of the invention
The present invention is intended to solve the deficiencies in the prior art, and provides a kind of device for core and a chill blow molding.
The present invention for achieving the above object, by the following technical solutions: a kind of device for core and a chill blow molding, it is characterized in that, comprise two symmetrically arranged half molds, be respectively left half module and right half module, half mold is provided with insert, insert is provided with three copper sheathings, copper sheathing inside is provided with magnet, insert side is provided with two heating tubes, opposite side is provided with semicircle chill, semicircle chill is inner at half mold by magnet adsorption, the inside of semicircle chill is provided with die cavity core, die cavity sand core internal is provided with three exhaust connecting holes, the top of two half mold joints is provided with penetrates Sha Kou.
Described magnet is powerful high temperature resistant magnet.
The invention has the beneficial effects as follows: the present invention can realize core and chill blow molding, the core made engages concordant, firm with chill, without the need to repairing and baking, and save multiple production process by the core that the present invention blows, and ensure that product size requirement, improve the quality of foundry goods inherence and outward appearance.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, a kind of device for core and a chill blow molding, it is characterized in that, comprise two symmetrically arranged half molds, be respectively left half module 2 and right half module 8, half mold is provided with insert 3, insert 3 is provided with three copper sheathings 4, copper sheathing 4 inside is provided with magnet 5, insert 3 side is provided with two heating tubes 1, opposite side is provided with semicircle chill 6, semicircle chill 6 is adsorbed on half mold inside by magnet 5, the inside of semicircle chill 6 is provided with die cavity core 10, die cavity core 10 inside is provided with three exhaust connecting holes 7, the top of two half mold joints is provided with penetrates sand mouth 9.
Described magnet 5 is powerful high temperature resistant magnet.
Operation principle of the present invention:
Magnet 5 is placed in copper sheathing 4, then by copper sheathing 4 with type close-fitting in insert 3 pre-manufactured hole, again insert 3 is fixed in left half module 2 and right half module 8 with type afterwards.Semicircle chill 6 is adsorbed in mould by magnet 5 and (lays during coremaking), by left half module 2 and right half module 8 and mould stand-by.
After each parts are connected and installed, mould is arranged on core shooter, left half module 2 and right half module 8 with mould state under undertaken being heated to technological requirement temperature by heating tube 1, open the right half module 8 of left half module 2, the semicircle chill 6 electric furnace being in advance preheated to 120 ~ 150 DEG C is laid successively and is adsorbed on magnet 5 position, close left half module 2, right half module 8, penetrate sand mouth by core shooter precoated sand is penetrated sand mouth 9 by mould to be blown into die cavity, after time to be solidified arrives, open left half module 2, right half module 8, take out the qualified core containing chill.Each chill is taken out of and closely engages with core along with the sand of solidifications in 6 exhaust connecting holes 7.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technical scheme is carried out; or directly apply to other occasion, all within protection scope of the present invention without improving.
