Abstract
The utility model discloses a butterfly valve die, which comprises an outer die and a core box. The core box is arranged in the outer die; the outer die comprises an upper cylinder and a lower cylinder which are overlapped together; flanges are respectively and movably mounted at two sides of the upper cylinder and the lower cylinder; short sections communicated with the interior of the upper cylinder and the lower cylinder are movably connected onto sidewalls of the upper cylinder and the lower cylinder; a bottom cover seals the bottom end of the lower cylinder; the middle part of the bottom cover is provided with a through hole and is buckled with a cover plate; the core box comprises a tube body; a plurality of annular lug bosses are respectively and movably mounted on an internal wall of the tube body from top to bottom; and radial through holes which are communicated with one another are respectively arranged in a sidewall of the tube body and the annular lug bosses. The butterfly valve die has the advantages that: the structure is reasonable, the disadvantages of box expansion, box bruising, burrs, air holes, difficulty in demolding, defects and the like, occurring in the casting operation of butterfly valves are completely overcome, the yield of products reaches 99%, the machining is power-saving and laborsaving, the working efficiency is increased, the labor intensity for workers is greatly alleviated, and the cost is lowered.
Description
Technical field
The utility model relates to a kind of butterfly valve mould.
Background technology
Butterfly valve is a kind of usefulness valve commonly used, is widely used in the industrial and agricultural production.The production of butterfly valve is to carry out the molten iron casting after being shaped in sandbox through the butterfly valve mould to form.Butterfly valve mould commonly used comprises external mold and core box; Said external mold comprises cylindrical shell, reaches with the front and back flange of cylindrical shell rear and front end flexible connection and pass through the pipe nipple that is connected mutually with the activity of cylindrical shell side; The tube upper end is sealed with bottom; The center of bottom is provided with through hole, and through hole is provided with removable cover, and core box is a straight tube-like.For ease of the demoulding, external mold carries out subdivision along diameter line, and the core box straight tube dissects along diameter line, becomes two arc rings; Annular boss and straight tube inwall are connected as a single entity, and the shortcoming of above-mentioned butterfly valve mould is: external mold is in sandbox during the demoulding, and the sand mold between pipe nipple both sides and the flange makes that external mold can't the demoulding; Each manufacturing enterprise all is through destroying the sand mold between pipe nipple and the flange, carrying out repairing after the demoulding, when core box and external mold are located again now; Need to establish support, when making casting like this, the case that often occurs rising, frustrate case, pore, crinosity and sting at two ends; Weight does not reach standard, and molding is difficult, occurs falling husky, damaged easily; Surface irregularity causes the butterfly valve blank processing after the casting time-consuming, and yield rate has only 75-80%.
The utility model content
The purpose of the utility model provides a kind of butterfly valve mould, and it is low to solve the butterfly valve blank yield rate that the existing reed valve die production goes out, processing difficulties, the problem that production cost is high.
The technical scheme of the utility model is following:
A kind of butterfly valve mould; Include external mold and core box, described core box places in the external mold, it is characterized in that: described external mold comprises upper and lower two cylindrical shells that stack together; The both sides of said upper and lower cylindrical shell are movably installed with flange respectively; Be connected with the pipe nipple that connects with upper and lower barrel on the sidewall of upper and lower cylindrical shell, the bottom end seal of said lower shell has bottom, and the middle part of said bottom is provided with through hole and fastens has cover plate;
Described core box comprises body, is movably installed with a plurality of annular boss on the inwall of said body from top to bottom respectively, is respectively equipped with the radial direction through hole that connects on the sidewall of said body He on a plurality of annular boss.
Described butterfly valve mould is characterized in that: described flange cooperates the both sides that are movably arranged on upper and lower cylindrical shell through jack with latch.
Described butterfly valve mould is characterized in that: described pipe nipple cooperates an end that is movably arranged on upper and lower cylindrical shell with latch through jack.
Described butterfly valve mould is characterized in that: described a plurality of annular boss cooperate on the inwall that is movably arranged on body from top to bottom with latch through jack respectively.
Owing to be to flexibly connect between pipe nipple and the upper and lower cylindrical shell, between flange and the upper and lower cylindrical shell all be through latch and through hole cooperate the realization flexible connection, so can directly remove latch during the demoulding; Remove pipe nipple and flange again, thereby make the sand mold between pipe nipple and the flange can not destroy, core box is when making the sand mold demoulding; Take off pin; Body can direct demold, and a plurality of annular boss also can be removed, and therefore the blank quality after the casting is high.
The beneficial effect of the utility model:
The utility model is rational in infrastructure; The case that rises that has occurred when thoroughly having solved the butterfly valve casting operation, frustrate drawbacks such as case, burr, pore, molding be difficult, damaged; The yield rate of product has reached 99%, and it is laborsaving to add the power saving in man-hour, has improved operating efficiency; Alleviate working strength of workers greatly, reduced cost.

Fig. 2 is the structural representation of the utility model core box.
The specific embodiment
Referring to Fig. 1,2, a kind of butterfly valve mould includes external mold and core box; Core box places in the external mold; External mold comprises upper and lower two cylindrical shells that stack together 1,2, and the both sides of upper and lower cylindrical shell 1,2 cooperate with latch 9 through jack respectively and are movably installed with flange 3, and jack cooperates with latch and is connected with the pipe nipple 4 that connects with upper and lower cylindrical shell 1,2 inside on the sidewall of upper and lower cylindrical shell 1,2; The bottom end seal of lower shell 2 has bottom 5, and the middle part of bottom 5 is provided with through hole and fastens has cover plate 6;
Core box comprises body 7, on the inwall of body 7 from top to bottom respectively jack cooperate with latch and be movably installed with three annular boss 8, be respectively equipped with the radial direction through hole that connects on the sidewall of body 7 He on three annular boss 8.
