Abstract
The utility model discloses a simple-structure full-floating type cold isostatic pressing die for manufacturing multichannel filter elements. The die comprises an external elastic wrapping sleeve, and a plurality of internal elastic expanding sleeves positioned in the external elastic wrapping sleeve; the upper and lower ends of the external elastic wrapping sleeve are provided with sealing members for supporting upper and lower ends of the internal elastic expanding sleeves; at least one end of each internal elastic expanding sleeve is an open end communicated with the outside of the die; the upper and lower sealing members are rubber plugs provided with a plurality of expanding sleeve fixing holes; each expanding sleeve positioning hole is matched with a corresponding internal elastic expanding sleeve; and hoops for tightly connecting the external elastic wrapping sleeve, the rubber plugs and the internal elastic expanding sleeves are arranged on the outer side faces of two ends of the external elastic wrapping sleeve. The die has a simple structure, the external elastic wrapping sleeve, the internal elastic expanding sleeves and the upper and lower sealing members are made of deformation materials, and the die is positioned in a full-floating internal and external balanced pressing state in the pressing process. The formed multichannel filter elements are as long as 1 meter, and the appearances and the channel shapes are regular.
Description
Technical field
The utility model relates to a kind of cold isostatic compaction mould of making the multichannel filter core.
Background technology
By the application's applicant application, publication number is that the application for a patent for invention file (calling reference paper in the following text) of CN102078962A discloses a kind of mould that is used for moulding multichannel filter core; This mould is through being designed to plug the form of " resilient sleeve+stay pipe "; Overcome the problem of plug demoulding difficulty, realized the cold isostatic compaction of intermetallic compound multichannel filter core first.Yet the structure of this mould is comparatively complicated, still is necessary to improve.
The utility model content
The technical problem that the utility model solved provides a kind of full-floating type cold isostatic compaction mould of manufacturing multichannel filter core simple in structure.
This mould comprises that outer elasticity jacket and Duo Gen are arranged in the elastic expansion sleeve of outer elasticity jacket; The seal at two ends about the elastic expansion sleeve in the two ends up and down of being somebody's turn to do outer elasticity jacket are respectively equipped with and support; In each elastic expansion sleeve have at least an end for the openend of the outside conducting of mould; The upper-lower seal body is the rubber stopper that is provided with a plurality of expansion set locating holes; Said each expansion set locating hole cooperatively interacts with corresponding interior elastic expansion sleeve respectively, is respectively equipped with on the lateral surface at elasticity jacket two ends outside outer elasticity jacket, rubber stopper and the close-connected anchor ear of interior elastic expansion sleeve.
Because the compression ratio of multichannel filter core moulding is bigger; When adopting this mould molding; Outer elasticity jacket can be axially and free shrink radially; And interior elastic expansion sleeve has preferably elasticity and can be convenient to the demoulding, and realizes the end sealing through the mutual compression between outer elasticity jacket, interior elastic expansion sleeve and the upper-lower seal body.
This mould structure is simple, and outer elasticity jacket, interior elastic expansion sleeve and upper-lower seal body are deformable material, lets mould in pressing process, be in the internal and external equilibrium compacting state of full floating.The more the passage filter core of moulding is 1 meter, and the shape of profile and passage is all fairly regular.
Description of drawings
Fig. 1 makes the structural representation of the full-floating type cold isostatic compaction mould of multichannel filter core for the utility model.
Be labeled as among the figure: rubber stopper 1, anchor ear 2, interior elastic expansion sleeve 4, outer elasticity jacket 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The full-floating type cold isostatic compaction mould of manufacturing multichannel filter core as shown in Figure 1; Comprise that outer elasticity jacket 3 and Duo Gen are arranged in the elastic expansion sleeve 4 of outer elasticity jacket 3; The seal at elastic expansion sleeve two ends about in the of 4 in the two ends up and down of being somebody's turn to do outer elasticity jacket 3 are respectively equipped with and support; Each interior elastic expansion sleeve 4 two ends is the openend with the outside conducting of mould; The upper-lower seal body is the rubber stopper 1 that is provided with a plurality of expansion set locating holes, said each expansion set locating hole respectively with corresponding in elastic expansion sleeve 4 cooperatively interact, be respectively equipped with on the lateral surface at elasticity jacket 3 two ends outside outer elasticity jacket 3, rubber stopper 1 and interior elastic expansion sleeve 4 close-connected anchor ears 2.
Claims (1)
