Abstract
The utility model relates to an interior run-through side valve pocket of loosing core lining mould, including the valve body base member, install the mould in the inner chamber of valve body base member, the left flange rigid coupling of valve body base member has the feed cylinder, and the right flange rigid coupling of valve body base member has right mandrel, it is equipped with the moulding-die core of lining plastics to impress to valve body base member inner chamber to slide in the feed cylinder, last mould in to right mandrel side inclined plane have a side mandrel, side mandrel in terminal surface and the right mandrel in the terminal surface inclined plane paste mutually. The utility model discloses a with the side core mould slant pack into in the upper die to make the interior terminal surface of side core mould laminate completely with the terminal surface inclined plane in the right side core mould, guarantee the valve body base member at the lining in-process with this, it is tight to laminate between last mould and the side core mould, prevents to line to mould the in-process and produces long-pending material defect, makes things convenient for the drawing of patterns, thereby has improved the once qualification rate and the lining quality of moulding of valve body base member inner chamber lining effectively.
Description
Technical Field
The utility model belongs to the technical field of the valve body technique and specifically relates to a mould is moulded to interior through side valve pocket lining of used is moulded to straight stroke valve pocket lining.
Background
The straight-stroke plastic-lined valve is a valve suitable for use under the condition of low-pressure special corrosive medium, its internal components are made of corrosion-resisting material, and its valve body is made up by using metal base body and lining a layer of special corrosion-resisting plastic, so that the corrosion-resisting property of said valve can be raised, and its production cost can be reduced.
In the existing plastic lining mould structure, the side mould core is positioned on the side surface of the upper mould, the side mould core is firstly installed in the valve body base body during installation, then the upper mould is installed, and during the plastic lining process of the valve body of the plastic lining valve, the problems of material accumulation defect, difficult demoulding, low plastic lining efficiency and the like are easily caused by poor adhesion between the upper mould and the side mould core, so that the one-time qualification rate of the plastic lining of the valve cavity is reduced, and the plastic lining quality of the valve cavity is difficult to ensure.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the not enough among the prior art, the utility model provides a can effectively improve the valve pocket lining and mould the qualification rate, ensure that the valve pocket lining moulds the interior through side valve pocket lining of quality and mould the mould of loosing core.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an interior run-through side valve pocket of loosing core lining mould, includes the valve body base member, installs the mould in the inner chamber of valve body base member, and the left flange rigid coupling of valve body base member has the feed cylinder, and the right flange rigid coupling of valve body base member has right mandrel, it is equipped with the moulding-die core of lining plastics to impress to valve body base member inner chamber to slide in the feed cylinder, last mould in to put the side mandrel to right mandrel side slope, side mandrel in terminal surface paste with right mandrel inner terminal surface slope mutually.
And the right core mold is connected with a right flange bolt of the valve body base body through a flange cover.
The utility model has the advantages that: the utility model discloses a with the side core mould slant pack into in the upper die to make the interior terminal surface of side core mould laminate completely with the terminal surface inclined plane in the right side core mould, guarantee the valve body base member at the lining in-process with this, it is tight to laminate between last mould and the side core mould, prevents to line to mould the in-process and produces long-pending material defect, makes things convenient for the drawing of patterns, thereby has improved the once qualification rate and the lining quality of moulding of valve body base member inner chamber lining effectively.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the valve body comprises a valve body base body, 2 parts of an upper die, 3 parts of a charging barrel, 4 parts of a right core die, 5 parts of a pressing die core, 6 parts of a side core die and 7 parts of a flange cover.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The lining plastic mould of the inner through side core-pulling valve cavity shown in fig. 1 comprises a valve body base body 1, an upper mould 2 is installed in an inner cavity of the valve body base body 1, a charging barrel 3 is fixedly connected to a left flange of the valve body base body 1, a right core mould 4 is arranged on a right flange of the valve body base body 1, and the right core mould 4 is connected with a right flange of the valve body base body 1 through a flange cover 7 in a bolt mode.
A side core mould 6 is obliquely arranged in the upper mould 2 towards the right core mould 4, the inner end surface of the side core mould 6 is attached to the inclined surface of the inner end surface of the right core mould 4, a pressing mould core 5 which is used for pressing lining plastic into the inner cavity of the valve body matrix 1 is arranged in the charging barrel 3 in a sliding way,
when the valve body base body 1 is installed, the upper die 2 is vertically arranged in an inner cavity of the valve body base body 1 and is connected well through bolts, then the right core die 4 and the flange cover 7 are connected into a whole and are connected with a right flange of the valve body base body 1 through bolts, the side core die 6 is obliquely arranged in the upper die 2, the inner end face of the side core die 6 is adjusted to be completely attached to the inclined face of the inner end face of the right core die 4 and then is fixed well with the valve body base body 1 through a screw rod, the flange of the charging barrel 3 and the left flange of the valve body base body 1 are fixed through bolts, lining plastic with the weighed weight is arranged from the charging barrel 3, finally the compression die core 5 is arranged in the charging barrel 3, and after the assembly, the next sintering process is carried out, and the lining plastic of the inner cavity of the valve body base body 1 is completed.
The utility model discloses a with 6 slants of side mandrel pack into in last mould 2 to make the interior terminal surface of side mandrel 6 laminate completely with the terminal surface inclined plane in the right mandrel 4, ensure with this that valve body base member 1 moulds the in-process at the lining, go up the laminating tightly between mould 2 and the side mandrel 6, prevent to line to mould the in-process and produce long-pending material defect, make things convenient for the drawing of patterns, thereby improved one time qualification rate and the lining quality of moulding of lining of 1 inner chamber of valve body base member effectively.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
