Abstract
The utility model discloses an improved structure of exhaust block, including an exhaust block body is provided with a positioning groove in connection coordination with the mold on the awwembling end face. Compared with the prior technology, the utility model has beneficial effects of: 1, simple and reasonable the overall structure, easy manufacturing, low cost; 2, positioning accuracy, malposition resistance, obvious exhaust effect, safe and reliable performance.
Description
Technical field
The utility model relates to a kind of exhaust piece, belongs to concentrate the exhaust equipment technical field, refers in particular to a kind of exhaust piece that is used to push down mould.
Background technology
Pore is common and insoluble a kind of die casting defective during die casting is produced, and much to the demanding part of air-tightness, causes part to be scrapped owing to the die casting blank porosity is high, thereby causes very big economic loss for die casting manufacturing enterprise.For overcoming this problem, all be by cinder ladle and airway being set in traditional die casting design, and each airway is connected together and then gas discharged by the exhaust piece is set from the exhaust piece at the die joint place in last moulding place of part.But because traditional die casting is not accurately controlled the location of exhaust piece, the perpendicularity and the depth of parallelism of exhaust piece, cause and be assembled in exhaust piece moving, fixed mold and behind matched moulds, may cause the exhaust piece to slide, gap between each tooth is inhomogeneous, thereby causes a certain section of exhaust piece blocked and cause gas not discharge smoothly from the exhaust piece.And be to solve exhaust piece blocking problem, also there is the part dealer to reach the problem of smooth and easy exhaust by the gap of strengthening the die venting piece, though this kind method can solve the exhausting problem of die casting, fly material but may cause in process of production, even the production safety accident may take place because of the die venting block gap is excessive.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, provides simple in structure, easy to manufacture, locatees accurately and practical and reliable exhaust piece.
In order to realize above-mentioned purpose, the utility model is realized by following technical scheme:
A kind of exhaust piece that improves structure comprises the exhaust block body, and described exhaust block body is provided with the detent that is connected cooperation with mould in the assembling end face.
Further, the perpendicularity of described exhaust block body and the depth of parallelism are controlled in 0.05 respectively.
Further, described exhaust block body is provided with the tooth-shape structure of evenly arranging in the opposing end surface of assembling end face.
Further, the profile of tooth quantity of described exhaust block body is 9～14.
The utility model compared with prior art, its beneficial effect is:
1, the overall structure advantages of simple is easy to manufacture, and cost is low;
2, dislocation is accurately avoided in the location, and exhaust effect is obvious and safe and reliable.
In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is a Facad structure schematic diagram of the present utility model.
Fig. 2 is a side structure schematic diagram of the present utility model.
Fig. 3 is a structure schematic diagram of the present utility model.
Fig. 4 is the tooth-shape structure schematic diagram.
The specific embodiment
Shown in Fig. 1～4, the exhaust piece of improvement structure described in the utility model comprises the left bank air parcel body and the right exhaust block body that are used, is assembled in respectively on dynamic model and the cover half.
Described each exhaust block body 1 is provided with the bar shaped detent 11 that is connected cooperation with mould in the assembling end face, opposing end surface in the assembling end face is provided with the tooth-shape structure 12 of evenly arranging, profile of tooth 12 quantity are decided on the shape and the complexity of product, are generally 9～14.Preferably, the perpendicularity and the depth of parallelism of described exhaust block body 1 are controlled in 0.05 respectively, thereby guarantee that exhaust block body 1 can be assembled on moving, the cover half accurately and avoids misplacing.
Because exhaust block body 1 has been provided with high-precision detent 11, can be accurate and firm be installed in is moving, on the cover half and be not moved, behind matched moulds, profile of tooth 12 gaps of exhaust piece are relatively even (as shown in Figure 4) just, during injection, press the liquid of chamber under the promotion of drift, to flow to mold cavity from minute flow cone always, simultaneously pressing chamber and mold cavity and mold cavity coating to push exhaust duct to because of the gas that vaporization at high temperature goes out, and then smoothly by outside the exhaust piece discharge mould.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
Claims (4)
