Abstract

The utility model discloses a blowing and indraft device for cleaning a casting cavity. The blowing and indraft device comprises a sundries discharging pipe (1) and a sundries discharging port (11) and is characterized by also comprising a rapid joint (2), a high-pressure air pipe (3) and an air pipe outlet (31), wherein the rapid joint (2) is mounted at the middle and lower position of the sundries discharging pipe (1); the high-pressure air pipe (3) is fixedly arranged at the position, close to the sundries discharging port (11), of the sundries discharging pipe (1); the direction of the air pipe outlet (31) is parallel with the direction of the sundries discharging port (11). According to the blowing and indraft device for cleaning the casting cavity, the technical effect that sundries in the casting cavity can be effectively and rapidly absorbed and removed is realized, and the product quality of a casting part is improved.

Description

A kind of casting mold cavity cleaning pressure-vaccum device

Technical field

The utility model relates to a kind of cleaning plant, and in particular, the utility model relates to a kind of casting mold cavity cleaning pressure-vaccum device.

Background technology

Sand casting this be a kind of traditional, still producing the casting method of a large amount of casting mold workpiece.It utilizes the grains of sand, water, clay and other materials to make the high-quality mold for molten metal.The two halves of the essential part mold of husky mould and other molds (upper drag box) cover and on core, form necessary inner chamber, whole assembly be carried out weight or clamped when preventing casting metal top box move.

Weak point of the prior art is: at casting die assembling process Sand, easily comes off, and the pollution of foreign matter to die cavity inside; The foreign material of casting mold cavity inside are very large on watering the impact of foundry goods, greatly reduce the quality of product.

Utility model content

The utility model provides a kind of casting mold cavity cleaning pressure-vaccum device, and its object is to absorb the impurity in die cavity, keeps cleaning in die cavity, improves the quality of product.

For realizing above object, the technical solution adopted in the utility model is: a kind of casting mold cavity cleaning pressure-vaccum device, it comprises impurity-discharging pipe (1), impurities removal outlet (11), it is characterized in that, it also comprises snap joint (2), high-pressure air pipe (3), tracheae outlet (31); Described impurity-discharging pipe (1) position, middle and lower part is provided with snap joint (2); High-pressure air pipe (3) is fixed on impurity-discharging pipe (1) near the position of impurities removal outlet (11); The direction keeping parallelism of the direction of tracheae outlet (31) and impurities removal outlet (11).

The beneficial effects of the utility model are: the utility model provides a kind of casting mold cavity cleaning pressure-vaccum device, and it can absorb the impurity in casting mold cavity fast and effectively, and cleaning is convenient; Simple in structure and reliable operation; Can improve the product quality of watering foundry goods.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

At the numerical reference described in Figure of description, be expressed as: 1, impurity-discharging pipe; 11, impurities removal outlet; 2, snap joint; 3, high-pressure air pipe; 31, tracheae outlet.

The specific embodiment

In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.

Referring to Fig. 1, a kind of casting mold cavity cleaning pressure-vaccum device, it comprises impurity-discharging pipe 1, impurities removal outlet 11, it is characterized in that, it also comprises snap joint 2, high-pressure air pipe 3, tracheae outlet 31; Described impurity-discharging pipe 1 position, middle and lower part is provided with snap joint 2; High-pressure air pipe 3 is fixed on impurity-discharging pipe 1 near impurities removal outlet 11 position; The direction keeping parallelism of the direction of tracheae outlet 31 and impurities removal outlet 11.

The operation principle of the present embodiment: tracheae outlet 31 pressure-airs that blow out, can make impurity-discharging pipe 1 bottom inlet produce negative pressure, direction and the impurities removal Way out keeping parallelism of tracheae outlet 31, for preventing turbulent generation, affect the effect of impurities removal; Thereby the foreign material of casting mold cavity inside are taken out of, guaranteed the environment that casting mold cavity inside is relatively clean, further guarantee the quality of cast member.

It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby which key element the process, method, article or the equipment that make to comprise a series of key elements not only comprise, but also comprise other key elements of clearly not listing, or be also included as the intrinsic key element of this process, method, article or equipment.The in the situation that of more restrictions not, the key element being limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment that comprises key element and also have other identical element.

Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred embodiment of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
