Description
Technical Field
The utility model belongs to the technical field of the valve rod mould and specifically relates to a convenient to use's valve rod mould.
Background
The valve rod is an important part of the valve and is used for transmission, an actuating mechanism or a handle is connected to the valve rod, and the valve rod directly drives the valve core to move or rotate below the actuating mechanism or the handle so as to realize the opening and closing or adjusting function of the valve. The valve rod is not only a moving part and a stressed part but also a sealing part in the opening and closing process of the valve. At the same time, it is impacted and corroded by the media and also rubs against the filler. The valve rod has high requirements on the size of the valve rod positioning column in the using process, and plays a key role in opening and closing.
The existing conventional die adopts straight surface positioning and curved surface positioning for positioning; and (5) performing material injection and encapsulation processing after positioning. Due to the consideration of cost, the tolerance requirement of a finished product cannot be met in the machining process of the valve rod metal piece, and the size is unstable. Because of the setpoint is fixed, when valve rod metalwork valve rod reference column processing surpassed the tolerance, will cause the valve rod reference column of valve rod finished product to transfinite and lead to the product to scrap. The defective rate is high, the defect is not easy to be found, the defect can be detected only by taking effort to fully check the size, and the detection cost is high. Meanwhile, due to the positioning requirement, the straight-surface positioning point and the curved-surface positioning point can only be attached to the valve rod metal piece, so that material overflow is caused in the material injection process, and the trouble of poor treatment of the subsequent processing burrs is caused. Therefore, it is desirable to design a valve stem mold that is easy to use.

Detailed Description
The preferred embodiments of the present invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1, a valve rod mold convenient to use comprises an upper mold 1 and a lower mold 2, wherein the lower end of the upper mold 1 is correspondingly connected with a material pressing mold 3, the upper end of the lower mold 2 is correspondingly connected with a middle plate mold 4, a cavity 5 is correspondingly arranged in the middle plate mold 4 and the material pressing mold 3, and a valve rod metal piece 6 is correspondingly arranged in the cavity 5; the valve rod has high requirements on the size of the valve rod positioning column in the using process, and plays a key role in opening and closing.
As shown in fig. 3, the valve rod metal part 6 includes a valve rod positioning column 61 and a valve rod connector 62, the valve rod positioning column 61 is of a columnar structure, and one end of the valve rod positioning column 61 is correspondingly provided with the valve rod connector 62;
as shown in fig. 2, the cavity 5 includes a positioning cavity 51 and a rubber coating cavity 52, the rubber coating cavity 52 is located between the middle plate mold 4 and the pressing mold 3, the positioning cavity 51 is located in the middle plate mold 4, a valve rod positioning post 61 is correspondingly arranged in the positioning cavity 51 in a matching manner, a valve rod connector 62 is correspondingly arranged in the rubber coating cavity 52 in a matching manner, a buffer area 521 is correspondingly arranged in the rubber coating cavity 52, the buffer area 521 is correspondingly communicated with the positioning cavity 51, and a cutting nozzle 522 is correspondingly arranged in the rubber coating cavity 52.
As shown in fig. 4, the outer diameter of the valve stem connector 62 is larger than the outer diameter of the valve stem positioning post 61. The cutting nozzle 522 is located above the buffer zone 521. The bottom of the positioning cavity 51 penetrates through the middle plate mold 4 to be correspondingly contacted with the upper end of the lower mold 2, and the bottom of the valve rod positioning column 61 is correspondingly contacted with the upper end of the lower mold 2.
This application sets up the buffers in the mould template, and the bottom (middle plate mould 4 bottom, the upper end of lower mould 2) that will fix a position chamber 51 sets up the locating area of valve rod reference column, decides the size of valve rod reference column by middle plate mould thickness. If the size of the valve rod positioning column is longer, the bottom of the valve rod connector 62 is higher than the cutting position, and the rubber coating in the rubber coating cavity moves downwards to buffer the part of the valve rod positioning column which is higher; if the size of valve rod locating column is too short, then move the valve rod locating column down, the buffer zone is gone into to valve rod connector 62 part, and the rubber coating shifts up the part that the buffering fell short, just so can guarantee the size of valve rod locating column. Because the positioning point is transferred to the bottom, after the material injection and encapsulation processing, the material overflow part is easily broken from the cutting nozzle due to the arrangement of the cutting nozzle, and the subsequent processing is easy.
The injection molding process, principle and method of the mold are known technologies and are not described herein again.
Although the invention has been shown and described in detail with respect to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
