Abstract
The invention relates to the technical field of casting, and particularly relates to a core box convenient for loose piece extraction. The core box comprises an upper core box and a lower core box, wherein a sand core groove is formed between the upper core box and the lower core box, and a demoulding device is arranged between upper and lower modules. The core box is simple in structure and is convenient and rapid to operate, different oblique cutting boards are used so that different loose pieces can move horizontally to be extracted; and the loose piece extraction can be implemented just by the operations of mould unloading and mould closing of the core box. The device can arrange in a small space, the production efficiency is greatly improved, and the quality of a product is improved.
Description
Technical field
The present invention relates to casting technology field, relate in particular to a kind of core box that loose piece extracts of being convenient to.
Background technology
Flourish along with the progress of science and technology and foundry industry, different casting methods has different casting mold preparing content.With most widely used sand casting is example, and casting mold is prepared to comprise Modeling Material preparation and moulding, make core two sport work.Be used in the sand casting moulding, make the various raw material of core; As cast roughing sand, moulding sand binder and other auxiliary materials; And the molding sand that is mixed with by them, core sand, coating etc. are referred to as Modeling Material; The task that Modeling Material is prepared is the requirement according to foundry goods, the character of metal, selects suitable roughing sand, binding agent and auxiliary material, is mixed into molding sand and the core sand with certain performance to them according to a certain percentage then.Sand blender commonly used has simpson mill, reverse-flow puddle mixer and continuous muller.The latter aims at the design of mixed chemical self-hardening sand, mixes continuously, and mulling speed is fast.
Moulding, to make core be according to the casting technique requirement, at definite good formative method, is ready to carry out on the basis of Modeling Material.The economic effect of the precision of foundry goods and whole production processes depends primarily on this procedure.In a lot of modern foundries, moulding, make core and all realized mechanization or automation.Sand mold moulding core-making installation commonly used has high, medium and low voltage moulding machine, gas towards moulding machine, box-less shoot squeeze molding machine of case, cold-box core making machine and hot box process machine, precoated sand core making machine etc.
Because the shape of blank part is different; Design need during core box can't depanning the place be arranged to loose piece; Mainly utilize cylinder directly to extract loose piece in the prior art; But so just taken bigger operating space, if change die joint or use manual work instead and get loose piece, the quality of product and production efficiency can not get guaranteeing.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of core box that loose piece extracts of being convenient to is provided, convenient and swift, can place narrow space.
The present invention adopts following technical scheme for realizing above-mentioned purpose: a kind of core box of being convenient to the loose piece extraction, comprise core box and following core box, and said going up forms the core groove between core box and the following core box, it is characterized in that: be provided with stripper apparatus between the said upper and lower mould.
Said core groove is at least two.
Said stripper apparatus mainly comprises the left oblique cutting plate that is arranged on the core box, the middle plate that is positioned at two core groove middle parts, right oblique cutting plate and the corresponding left loose piece on the core box, middle loose piece, the right loose piece of being arranged on down; Loose piece is two in the middle of said; Be respectively equipped with jack and following jack, said upward jack and middle plate are slidingly matched; Be provided with the left and right jack that cooperates with left oblique cutting plate and right oblique cutting plate respectively in the middle of said left loose piece, the right loose piece; Be respectively equipped with release link in the said jack, said two release links connect through connecting rod, and said connecting rod is provided with the oblique cutting plate that resets that cooperates with said jack down; Said release link bottom is provided with stage clip, and the outer wall of said left loose piece and right loose piece is equipped with extension spring.
The invention has the beneficial effects as follows: the present invention is simple in structure, and simple operation is extracted loose piece thereby through different oblique cutting plates different loose pieces are laterally moved, and just die sinking, the mould assembling action of core box can be accomplished loose piece and must extract.This device can be provided with in less space, has improved production efficiency greatly, has promoted the quality of product.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, go up core box; 2, following core box; 3, core groove; 4, left oblique cutting plate; 5, middle plate; 6, right oblique cutting plate; 7, left loose piece; 71, left jack; 8, middle loose piece; 81, go up jack; 82, following jack; 9, right loose piece; 91, right jack; 10, release link; 11, connecting rod; 12, the oblique cutting plate that resets; 13, stage clip; 14, extension spring; 15, core.
The specific embodiment
Specify the specific embodiment of the present invention below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of core box of being convenient to the loose piece extraction comprises core box 1 and following core box 2; Said going up forms core groove 3 between core box and the following core box; The core groove is used for splendid attire core 15, separates for the ease of last core box and following core box, is provided with stripper apparatus between the said upper and lower mould.In the present invention, said core groove is at least two.In the present invention; Said stripper apparatus comprises that mainly the left oblique cutting plate 4 that is arranged on the core box, the middle plate 5 that is positioned at two core groove middle parts, right oblique cutting plate 6 and correspondence are arranged on down left loose piece 7, middle loose piece 8, the right loose piece 9 on the core box; Loose piece 8 is two in the middle of said; Be respectively equipped with jack 81 and following jack 82, said upward jack and middle plate are slidingly matched; Be provided with the left and right jacks 71,91 that cooperate with left oblique cutting plate and right oblique cutting plate respectively in the middle of said left loose piece 7, the right loose piece 9; Be respectively equipped with release link 10 in the said jack, said two release links connect through connecting rod 11, and said connecting rod 11 is provided with the oblique cutting plate 12 that resets that cooperates with said jack 82 down; Said release link bottom is provided with stage clip 13, and the outer wall of said left loose piece and right loose piece is equipped with extension spring 14.
The present invention is simple in structure, and simple operation is extracted loose piece thereby through different oblique cutting plates different loose pieces are laterally moved, and just die sinking, the mould assembling action of core box can be accomplished loose piece and must extract.This device can be provided with in less space, has improved production efficiency greatly, has promoted the quality of product.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
