Abstract

The utility model discloses an internal mould positioning structure in a forming mould and a cold isostatic pressing mould for filtering tubes. The internal mould positioning structure free of subsequent bottom sealing comprises a support arranged on an external mould, a gap for forming thickness of a product wall is reserved between the internal mould and the support, a positioning rod made of materials which are same or similar to those of the product is arranged between the internal mould and the support, and two ends of the supporting rod are inserted into the support and a positioning hole on the internal mould respectively. Since the positioning rod is made of materials which are same or similar to those of the product, the positioning rod can be integrally pressed with the product during mould forming and is constantly connected onto the product after demoulding so as not to generate through holes on the product, and bottom sealing is not needed. The utility model further discloses a cold isostatic pressing mould for filtering tubes, which utilizes the internal mould positioning structure to form closed ends of the filtering tubes.

Description

The internal mold location structure in the mould and the cold isostatic compaction mould of chimney filter
Technical field
The utility model relates to the internal mold location structure in the mould, and relates to the cold isostatic compaction mould of the filter core that adopts this structure.
Background technology
When using at present the bigger filter core of cold isostatic compaction mould manufacturing dimension, exist the plug can't pinpoint problem, cause the product wall unevenness, thereby have a strong impact on the intensity of filter core.If use locating piece that plug is positioned; Product after the moulding must produce through hole in the placement of locating piece; Need seal (being commonly called as back cover handles) to this through hole, thereby produce the caused poor sealing problems such as the elevated temperature heat coefficient of expansion of Yin Gaowen switching performance, foreign material between encapsulant and the filter core.
Granted publication has been number for the utility model patent of CN201784027U (calling reference paper in the following text) discloses a kind of mould that adopts the isostatic cool pressing method to come moulding single hole filter core, and specifically discloses a, plug (being referred to as stay pipe in the reference paper); B, jacket (being referred to as rigid enclosure in the reference paper); The two ends of c, jacket are respectively equipped with the last seal (being referred to as drive end bearing bracket in the reference paper) and the lower seal body technical characterictics such as (being referred to as rear end cap in the reference paper) of double as plug supporter.Above-mentioned technical characterictic is the requisite part of cold isostatic compaction mould of chimney filter.
The utility model content
First technical problem that the utility model solved provides a kind of internal mold location structure of carrying out in the mould that back cover handles follow-up of need not.This internal mold location structure can be used for the plug in the cold isostatic compaction mould of chimney filter is positioned, and also can be used for the internal mold location in other moulds.
For this reason; This internal mold location structure comprises the supporter that is arranged on the external mold; Be provided with the spacing that forms the product wall thickness between internal mold and this supporter; Between said internal mold and supporter, also be provided with by with the made backstay of material of the same or similar character of this product, the two ends of this backstay insert on the supporter respectively and internal mold on locating hole in.
The material of so-called similar quality is meant that the high temperature switching performance of storeroom is better, the elevated temperature heat coefficient of expansion is approaching.Because it is made that backstay adopts with the material of the same or similar character of this product; Therefore can in die molding process, directly become one with the product pressure; Backstay is connected on the product all the time thereby can on product, produce through hole after the demoulding; And can keep the good high-temperature sealing between backstay and the product, handle so also just need not to carry out again back cover.
Second technical problem that the utility model solved provide a kind of adopt above-mentioned internal mold location structure come moulding chimney filter blind end the cold isostatic compaction mould.
For this reason, this mould comprises plug and the jacket that is sleeved on this mandrel outer, and the two ends of this jacket are respectively equipped with the last seal and the lower seal body of double as plug supporter, and the inboard of lower seal body is provided with groove, the bottom of plug and this groove fit; Be provided with between the top of last seal and plug by with the made backstay of material of the same or similar character of this chimney filter, insert respectively in the locating hole on seal inboard and plug top at the two ends of this backstay.
Above-mentioned chimney filter has an open end and blind end.Moulding is come by the bottom and the lower seal body of plug in the open end, and blind end then comes moulding by top, backstay and the last seal of plug.Because this mould adopted aforesaid internal mold location structure, so backstay is directly become one with the chimney filter pressure in die molding process, backstay is connected on the chimney filter all the time thereby can on product, produce through hole after the demoulding, so also just need not to carry out the back cover processing again.
The beneficial effect of the utility model is following: both can accurately locate internal mold, and need not again at the follow-up back cover that carries out, and can also guarantee the sealing property between backstay and the product simultaneously.
Description of drawings
Fig. 1 is the structural representation of the cold isostatic compaction mould of the utility model chimney filter.
Fig. 2 is the structural representation of the chimney filter of employing Mold Making shown in Figure 1.
Be labeled as among the figure: go up seal 1, backstay 2, plug 3, jacket 4, anchor ear 5, lower seal body 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1; Cold isostatic compaction mould with chimney filter of internal mold location structure comprises plug 3 and the jacket 4 that is sleeved on outside this plug 3; The two ends of this jacket 4 are respectively equipped with the last seal 1 and lower seal body 6 of double as plug supporter; The inboard of lower seal body 6 is provided with groove, the bottom of plug 3 and this groove fit; Be provided with between the top of last seal 1 and plug 3 by with the made backstay 2 of the material of the same or similar character of this chimney filter, insert respectively in the locating hole on seal 1 inboard and plug 3 tops at the two ends of this backstay 2.
Shown in Fig. 1~2, above-mentioned chimney filter has an open end and blind end.Moulding is come by the bottom and the lower seal body 6 of plug 3 in the open end, and blind end then comes moulding by top, backstay 2 and the last seal 1 of plug 3.Because the backstay 2 of this mould has adopted with the material of the same or similar character of this chimney filter made; Therefore can in die molding process, directly become one with the product pressure; Backstay is connected on the product all the time thereby can on product, produce through hole after the demoulding; And can keep the good high-temperature sealing between backstay and the product, handle so also just need not to carry out again back cover.
