Structure intensity, rigidity, case hardness, surface roughness and machining accuracy all have higher requirements, and the development level of mould production is machine
One of important symbol of tool manufacture level.
Utility model content
The purpose of this utility model is to provide a kind of step deflation casement, current to solve to propose in above-mentioned background technology
The common step mould extruding of in the market is to form the problem of confined space is felt suffocated.
To achieve the above object, the utility model provides following technical scheme：A kind of step deflation casement, including step mould
External mold, is inlaid with step core rod box inside the step mould external mold, and step mould external mold is internally provided with the first stomata, described
It is sheathed with first step hole on the outside of rank core rod box, and step core rod box is internally provided with the second stomata, outside the first step hole
Side is communicated with the first stomata, and second step hole is communicated with the right side of first step hole, and the 3rd is connected with the inside of second stomata
Stepped hole, the 3rd stepped hole right side are communicated with the 4th stepped hole.
Preferably, the step mould external mold internal structure is hollow-core construction, and its internal structure is step-like structure.
Preferably, the step core rod box internal structure is via-like structure, and its outside is fitted in step mould external mold
Wall.
Preferably, the internal diameter in the first step hole and step core rod box external diameter are in the same size, and on the outside of first step hole
It is communicated with the first stomata.
Preferably, the 4th stepped hole internal diameter and second step hole internal diameter are in the same size, and the two is concentric.
Compared with prior art, the beneficial effects of the utility model are：A kind of step deflation casement is in extruded product mistake
Cheng Zhong, will not by or by very little axial compressive force, its construct rationally and structure stability it is good, so as to ensure that plus
Work process can be smoothed out, while the step mould is separated split-type structural at the step surface of step nib, inside it
Step mould is also split-type structural separated at the step surface of step nib, and this kind of technique greatly reduces the difficult processing of mould
Degree, and its structural stability is preferable, and its integral structure, the quantity of component is reduced, it is convenient for assembly, placed at step
Stomata, effectively the confined space that product is formed when step extrudes can be felt suffocated and be discharged so that the product of extruding is fuller.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：Including step mould external mold 1, in step mould external mold 1
Portion is inlaid with step core rod box 2, and step mould external mold 1 is internally provided with the first stomata 4, and the internal structure of step mould external mold 1 is sky
Core structure, and its internal structure is step-like structure, hollow shape structure is that the vacating space of step core rod box 2 is placed, and its
Internal step-like structure can be very good to carry out step core rod box 2 spacing, and the outside of step core rod box 2 is sheathed with first step
