Abstract

The utility model relates to a gap bridge pouring device, which saves pouring time to more uniformly distribute gravity of pouring liquid in a mould cavity, and also can reduce the generation of air bubbles in the pouring liquid in a pouring process and can completely mould a pouring piece. The gap bridge pouring device comprises a sand box; a bridge type body is arranged at the upper end of the sand box and one side of a pouring channel is communicated with the bottom of the mould cavity of the sane box; the other end of the sand box is arranged in the bridge type body; and a pouring cup is fixed at one side of the upper end of the bridge type body and is communicated with a transverse pouring channel in the bridge type body. The gap bridge pouring device gas the advantages that: firstly, the dispersion of the pouring liquid in the mould cavity is accelerated and the pouring liquid can be more uniformly distributed in the mould cavity; workers can conveniently control the center of gravity of the pouring piece and the molding of the large-size irregular pouring piece is ensured to be complete, so that the yield of a product is improved; and secondly, the effect of accelerating a flowing speed of the pouring liquid in the mould cavity is realized; not only can the casting time be saved, but also a production progress is accelerated; and gas in the pouring liquid is easy to discharge and the generation of the air bubbles in the pouring piece is reduced.

Description

The gap bridge pouring device

Technical field

The utility model relates to a kind of time of both having saved casting; Make the gravity centre distribution of casting liquid in the die cavity more even; Can reduce in casting cycle the generation of bubble in the casting liquid again, make the foundry goods pouring device of can moulding passing a bridge completely, belong to pouring device and make the field.

Background technology

In the casting cycle of original large-scale irregular shape foundry goods, to take casting liquid is directly injected the mode in the sandbox die cavity, casting liquid flows in the die cavity through the pouring channel that is communicated with the die cavity upper end; But such casting form not only need consume the more time; And it is even inadequately to be prone to make the interior casting of die cavity liquid to distribute, and center of gravity is difficult to control, thereby causes the foundry goods moulding incomplete; The liquid of casting is simultaneously filled with die cavity from the bottom to top; Be not easy to the to cast discharge of gas in the liquid can cause blow hold too much, thereby reduce the qualification rate of product.

The utility model content

Purpose of design: avoid the weak point in the background technology; Design a kind of time of both having saved casting; Make the gravity centre distribution of casting liquid in the die cavity more even, can reduce the generation of bubble in the casting liquid in casting cycle again, make the foundry goods pouring device of can moulding passing a bridge completely.

Design: in order to realize above-mentioned purpose of design.Sandbox upper end is provided with the bridge-type body, and running channel one side is communicated with the cavity bottom of sandbox, and the other end is arranged in the bridge-type body, and cup is fixed in a side on the bridge-type body, and the design that is communicated with running channel in the bridge-type body, is the major technique characteristic of the utility model.The purpose of doing like this is: the bridge-type body is mainly used in the location of running channel, and casting liquid flows in the running channel from the cup of bridge-type body top, and injects in the die cavity of sandbox through running channel; Because running channel is communicated with the bottom of die cavity, casting liquid injects from cavity bottom under the guiding of running channel, has accelerated the diffusion of casting liquid in the die cavity; Make its being more evenly distributed in die cavity, be convenient to the center of gravity that the staff controls foundry goods, guaranteed that the moulding of large-scale irregular shape foundry goods is complete; Thereby improved the qualification rate of product, along with the carrying out of casting cycle, the casting fluid power that the back is injected enough plays the effect of the moving speed of casting flow in the aggravation die cavity; Not only save the time of casting, accelerated manufacturing schedule, and the discharge of gas in the liquid that is easy to cast; Reduced the generation of bubble in the foundry goods, simple in structure, economical and practical; Reliable in function can make the molding effect of casting of large-scale irregular foundry goods better, thereby increase competitiveness of product.

Technical scheme: a kind of gap bridge pouring device, it comprises sandbox, said sandbox upper end is provided with the bridge-type body; Running channel one side is communicated with the cavity bottom of sandbox; The other end is arranged in the bridge-type body, and cup is fixed in bridge-type body upper end one side, and is communicated with running channel in the bridge-type body.

The utility model is compared with background technology; The one, accelerated the diffusion of casting liquid in the die cavity, make its being more evenly distributed in die cavity, be convenient to the center of gravity that the staff controls foundry goods; The moulding that has guaranteed large-scale irregular shape foundry goods is complete, thereby has improved the qualification rate of product; The 2nd, can play the effect of the moving speed of casting flow in the aggravation die cavity, not only saved the time of casting, accelerated manufacturing schedule, and the discharge of gas in the liquid that is easy to cast, reduced the generation of bubble in the foundry goods; The 3rd, simple in structure, economical and practical, reliable in function can make the molding effect of casting of large-scale irregular foundry goods better, thereby increase competitiveness of product.

Description of drawings

Fig. 1 is the structural representation of gap bridge pouring device.

The specific embodiment

Embodiment 1: with reference to accompanying drawing 1.A kind of gap bridge pouring device, it comprises sandbox 1, said sandbox 1 upper end is provided with bridge-type body 2; Running channel 3 one sides are communicated with die cavity 4 bottoms of sandbox 1, and the other end is arranged in the bridge-type body 2, and cup 5 is fixed in bridge-type body 2 upper ends one side; And is communicated with running channels 3 in the bridge-type body 2, the longitudinal section of cup 5 be little down big trapezium structure, bridge-type body 2 is mainly used in the location of " Z " font running channel 3; Casting liquid flows into running channel 3 from the cup 5 of bridge-type body 2 tops; And in the die cavity 4 through running channel 3 injection sandboxs 1, its manufacture craft is a prior art, is not described herein at this.

What need understand is: though the foregoing description is to the mentality of designing of the utility model simple text description of contrasting; But these text descriptions; Just the simple text of the utility model mentality of designing is described; Rather than to the restriction of the utility model mentality of designing, any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the utility model.
