Description
Technical field
The utility model relates to a kind of Design of Dies structure of the shaping valve circle for centre type butterfly valve, belongs to butterfly valve component technology field.
Background technology
Valve circle is as one of the part of centre type butterfly valve, its effect shows the sealing aspect of valve circle, belong to rubber, the shaping of this series products needs process important process to be the sulfuration of rubber, sulfuration is the process that the rubber of mecystasis is formed with the rubber of elastic stage under the effect of pressure, temperature, time three elements, realized by rubber mold, rubber mold is divided into rubber mold, rubber transfer die, rubber injection mould, rubber extrusion mold.
Utility model content
The purpose of this utility model is the Design of Dies structure proposing a kind of shaping valve circle for centre type butterfly valve, to meet the needs of valve circle large-scale industrial production.
The utility model adopts following technical scheme: a kind of Design of Dies structure of the shaping valve circle for centre type butterfly valve, it is characterized in that, comprise patrix, middle mould, counterdie, main core rod, side form core, described middle mould is arranged between described patrix and described counterdie, the centre of described middle mould has main through hole, the side of described middle mould has side through hole, and described main core rod and described main through hole are connected, and described side form core and described side through hole are connected.
Preferably, side form core is stepped, and the radial dimension at the close main core rod place of side form core is less than the radial dimension away from main core rod place of side form core, and described side form core is used for forming the shoulder hole of valve circle both sides.
Preferably, main core rod inside has locating hole, and the radial dimension of locating hole is more than or equal to the radial dimension of side form core near main core rod place.
Preferably, the outside of side form core has handle hole, and handle hole is equipped with handle, and handle is used for rotary side core rod and is screwed in described side through hole.
Preferably, middle mould be provided with projection up and down, patrix is provided with the shrinkage pool with male cooperation, and counterdie is provided with the shrinkage pool with male cooperation.
Preferably, it is 9 degree that protruding limit, left side is tilted to the right with angle formed by vertical direction, and passing to middle mode convertion after patrix is under pressure through 9 degree of inclined-planes is radial mold clamping force, by tight for middle die clamp.
Preferably, middle mould adopts line to separate mode and cuts into two halves, to facilitate the taking-up of valve circle.
Preferably, side form core, side through hole are two.
The beneficial effect that the utility model reaches: (1) side form core is used for forming the shoulder hole of valve circle both sides, it coordinates with the locating hole of main core rod and can prevent from valve circle in mold process from producing being out of shape; (2), after patrix is under pressure, passing to middle mode convertion through the inclined-plane of 9 degree is radial mold clamping force, by tight for middle die clamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The implication marked in figure: 1-counterdie, 2-side form core, 3-patrix, mould in 4-, the main core rod of 5-, 6-valve circle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 be structural representation of the present utility model, the utility model proposes a kind of Design of Dies structure of the shaping valve circle for centre type butterfly valve, comprise patrix 3, middle mould 4, counterdie 1, main core rod 5, side form core 2, middle mould 4 is arranged between patrix 3 and counterdie 1, the centre of middle mould 4 has main through hole, the side of middle mould 4 has side through hole, and main core rod 5 is connected with main through hole, and side form core 2 and side through hole are connected.
Side form core 2 is stepped, and the radial dimension at close main core rod 5 place of side form core 2 is less than the radial dimension away from main core rod 5 place of side form core 2, and side form core 2 is used for forming the shoulder hole of valve circle 6 both sides; Main core rod 5 inside has locating hole, and the radial dimension of locating hole is more than or equal to the radial dimension of side form core 2 near main core rod 5 place; The outside of side form core 2 has handle hole, and handle hole is equipped with handle, and handle is used for rotary side core rod 2 and is screwed in side through hole; Middle mould 4 be provided with projection up and down, patrix 3 is provided with the shrinkage pool with male cooperation, and counterdie 1 is provided with the shrinkage pool with male cooperation; It is 9 degree that protruding limit, left side is tilted to the right with angle formed by vertical direction, passes to middle mould 4 be converted to radial mold clamping force, by tight for middle die clamp after patrix 3 is under pressure through 9 degree of inclined-planes; Middle mould 4 adopts line to separate mode and cuts into two halves, to facilitate the taking-up of valve circle 6; Side form core 2, side through hole are two.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
