Abstract
The utility model relates to a mold, particularly to an oil seal mold with the lip thereof stuck with a PTFE sheet, which comprises an upper mold, a middle mold and a lower mold. The oil seal mold is characterized in that the mold also comprises a positioning core, a PTFE sheet is tightly pressed and fixed on the positioning core, and the middle mold comprises a middle upper mold and a middle lower mold. The oil seal mold provided by the utility model solves the problem that the PTFE sheet is not uniformly stuck at the lip of the mold in the prior art, so as to affect esthetic appearance and not to bring the superior properties of the PTFE sheet into full play. The oil seal mold can ensure good sealing effect, and can meet practical demand.
Description
Technical field
The utility model relates to a kind of mould, and especially a kind of lip pastes the oil sealing mould of PTFE sheet.
Background technology
Lip pastes the oil sealing of PTFE sheet and generally is made up of skeleton, rubber and PTFE sheet, paste the PTFE sheet on the oil seal lip, it has more the good characteristic of wear-resisting, high temperature resistant and anti-various media than common gum lip oil sealing, and it is mainly used in higher automobile engine crankshaft of rotating speed and similar operating mode.Common rubber lip is pasted PTFE sheet oil sealing at present, need make rubber and PTFE sheet bonding by the sulfuration operation in mould, pastes PTFE sheet oil sealing product thereby obtain lip; And common mould structure, form by three layers of mould of upper, middle and lower, during the sulfuration operation, the PTFE sheet is not fixed in die cavity, the power that produces is inhomogeneous because rubber flows in die cavity, or because of other a variety of causes, makes the PTFE sheet produce deflection, cause the oil seal lip paster inhomogeneous, cause product appearance of poor quality, the more important thing is because deflection makes some place of lip not paste the PTFE sheet, do not bring into play the good characteristic of PTFE sheet, thereby influence sealing effectiveness, to need a kind of lip PTFE sheet to paste evenly attractive in appearance for this reason, can give full play to the good characteristic of PTFE sheet, and the mould that sealing effectiveness is good satisfies the needs of actual conditions with this.
The utility model content
A kind of lip of the present utility model pastes the oil sealing mould of PTFE sheet, its solved the ubiquitous lip PTFE of original mould sheet paste inhomogeneous, the influence attractive in appearance, and can't give full play to the shortcoming of PTFE sheet good characteristic, it has can guarantee the excellent sealing effect advantage, can satisfy the needs of actual conditions.
The technical scheme that the utility model adopted is:
A kind of lip pastes the oil sealing mould of PTFE sheet, comprises patrix, middle mould and counterdie, it is characterized in that: also comprise the location core.
Described a kind of lip pastes the oil sealing mould of PTFE sheet, and its location core compresses the PTFE sheet in its position, and the PTFE sheet is fixed.
Described a kind of lip pastes the oil sealing mould of PTFE sheet, patrix and middle counterdie two parts during wherein mould comprises.
Like this when work, a kind of lip of the present utility model pastes the oil sealing mould of PTFE sheet, when the sulfuration operation, at first compress the location core by rubber mobile power that is produced in the film chamber, thereby compress the PTFE sheet by the location core, the PTFE sheet is fixed,, thereby made the PTFE of lip place sheet paste evenly because the rubber power that flows can not draw the PTFE sheet partially.
A kind of lip of the present utility model pastes the oil sealing mould of PTFE sheet, its solved the ubiquitous lip PTFE of original mould sheet paste inhomogeneous, the influence attractive in appearance, and can't give full play to the shortcoming of PTFE sheet good characteristic, it has can guarantee the excellent sealing effect advantage, can satisfy the needs of actual conditions.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the oil enveloping structure schematic diagram that lip pastes the PTFE sheet;
Fig. 2 is the oil sealing mould structure schematic diagram that original lip pastes the PTFE sheet;
Fig. 3 is the oil sealing mould structure schematic diagram that a kind of lip of the utility model pastes the PTFE sheet.
Among the figure, 1 is patrix, and 2 is middle mould, and 3 is middle patrix, and 4 is middle counterdie, and 5 is counterdie, and 6 are the location core, and 7 is the PTFE sheet, and 8 is lip.
The specific embodiment
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, wherein Fig. 2 is the oil sealing mould that original lip pastes the PTFE sheet, comprises patrix 1, middle mould 2 and counterdie 5.
Fig. 3 is the oil sealing that a kind of lip of the present utility model pastes the PTFE sheet, comprises patrix 1, middle mould 2 and counterdie 5, it is characterized in that: also comprise location core 6; The position of location core 6 can compress PTFE sheet 7, makes PTFE sheet 7 fixing; Patrix 3 and middle counterdie 4 two parts during middle mould 2 comprises.
Like this when work, a kind of lip of the present utility model pastes the oil sealing mould of PTFE sheet, when the sulfuration operation, at first compress location core 6 by rubber mobile power that is produced in the film chamber, thereby compress PTFE sheet 7 by location core 6, make PTFE sheet 7 fixing,, thereby make lip 8 PTFE of place sheets 7 paste evenly because the rubber power that flows can not draw PTFE sheet 7 partially.
A kind of lip of the present utility model pastes the oil sealing mould of PTFE sheet, its solved the ubiquitous lip PTFE of original mould sheet paste inhomogeneous, the influence attractive in appearance, and can't give full play to the shortcoming of PTFE sheet good characteristic, it has can guarantee the excellent sealing effect advantage, can satisfy the needs of actual conditions.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
