Description

A kind of water conservancy diversion mould of DRV
Technical field
The utility model belongs to a kind of mould for making the annex articles for use of DRV, especially belongs to a kind of use In the mould of the baffle for making DRV.
Background technology
DRV baffle casting structure is complicated, common two casees parting methods can not Foundry Production, at present to system Make DRV baffle casting mainly to be produced by the way of three casees partings.Three casees partings be directed to casting height it is higher or Baroque situation using three sandboxes manufacture casting method, many compared to two casees partings cheeks.Therefore use Three casees DRV baffle casting of parting method production have two die joints due to the mid-module of three casees partings, easily produce Joint flash defect is given birth to, and the dimensional accuracy of DRV baffle casting short transverse is reduced;Three casees the Jing Yin of parting stop simultaneously Return valve baffle casting die manufacture difficulty is big, the cycle is long, operate more complicated, productivity ratio it is low, be also unsuitable for sand mo(u)ld frame, level Line and vertical line are produced.How can prevent DRV baffle casting from producing joint flash defect, and Jing Yin non-return can be improved The dimensional accuracy of valve baffle casting short transverse;DRV baffle casting die manufacture difficulty can also be reduced, shortened Manufacturing cycle is long, easy operation, productivity ratio are high, and the DRV for being also adapted to the production of sand mo(u)ld frame, horizontal line and vertical line is led Two casees parting moulds of hydro-hardware are the problems for needing to solve.
Utility model content
Technical problem to be solved in the utility model is:A kind of water conservancy diversion mould of DRV is provided.Using this The water conservancy diversion mould of DRV can not only prevent DRV baffle casting from producing joint flash defect, improve Jing Yin non-return The dimensional accuracy of valve baffle casting short transverse;DRV baffle casting die manufacture difficulty can also be reduced, shortened Manufacturing cycle is long, easy operation, productivity ratio are high, moreover it is possible to be suitable for the production of sand mo(u)ld frame, horizontal line and vertical line.
The utility model solve above-mentioned technical problem technical scheme be:A kind of water conservancy diversion mould of DRV, bag Baffle mold, baffle casting pressing port are included, it is characterized in that:The baffle mold has upper box and lower box, should Upper box and lower box are flexibly connected;Be respectively provided with top box sand mold and nowel sand mold in the upper box and lower box, it is described on One end in case sand mold and nowel sand mold is installed with the dry core bodys of A, and the other end is installed with the dry core bodys of B being engaged with the dry core bodys of the A; The hat shape a part of spherical in shape of the dry core bodys of A, another part is in round table-like, and the dry core bodys of A are smaller in round table-like part One end end of diameter sets the U-shaped pit of oriented its inner recess, and the dry core bodys of B are in torus shape, and the dry core bodys of the B have One outer wall and to the inclined inwall of its one end, the internal diameter of the internal diameter more than the other end of the dry core body one end of the B, when the dry core bodys of the B When the end of larger interior diameter one end againsts the cap bottom of the A dry core body spherical caps, the round table-like part of the dry core bodys of A and B The partly molding cavity of the casting baffle is not contacted and formed between the dry inclined inwall of core body;The dry core bodys of B are away from the dry cores of the A The inwall of the circular passage and dry core bodys of the B set in circular passage, the dry core body core bodys of B is provided with the core body of body one end Between be provided with least 3 wedgy passages;Formed between the round table-like part of the dry core bodys of A and the inclined inwall of the dry core bodys of B The casting partly molding cavity of the baffle, the dry core bodys of the A in one end end of the small diameter of round table-like part set to it The annular set in the circular passage set in the dry core body core body of the U-shaped pit of inner recess, the B and the dry core body core bodys of the B At least 3 wedgy passages set between passage and the dry core body inwalls of the B connect after being full of by molten iron and form water conservancy diversion successively Chaeta base;
The both sides of the outer wall of the dry core bodys of A hat shape spherical in shape are correspondingly arranged on the A projections of protrusion, the dry cores of B Body is correspondingly arranged on the B projections of protrusion near the both sides of centre position outer wall, on the top box sand mold and nowel sand mold respectively according to It is secondary to be provided with the A projections and the dry core body outer wall both sides pair of B being correspondingly arranged with the outer wall both sides of the A dry core body hat shape spherical in shape The B projections that should be set distinguish the C grooves and D grooves of corresponding cooperation, when the outer wall both sides of the A dry core body hat shape spherical in shape The B projections that the A projections that are correspondingly arranged, the dry core body outer wall both sides of B are correspondingly arranged insert the top box in interference fit respectively When in the C grooves and D grooves set gradually respectively on sand mold and nowel sand mold, the dry core bodys of A, the axis and the B of the dry core bodys of B The center line of the circular passage vertical section set in dry core body core body is consistent.
The beneficial effects of the utility model are:Because the utility model baffle mold has upper box and lower box, The upper box and lower box are flexibly connected;Top box sand mold and nowel sand mold, the top box are respectively provided with upper box and lower box One end in sand mold and nowel sand mold is installed with the dry core bodys of A, and the other end is installed with the dry core bodys of B being engaged with the dry core bodys of the A;And When the end of the dry core body larger interior diameter one end of the B againsts the cap bottom of the dry core body spherical caps of A, the round table-like part of the dry core bodys of A The partly molding cavity of the casting baffle is not contacted and formed between the B inclined inwalls of dry core body;The dry core bodys of B are away from the dry cores of the A It is provided with the core body of body one end between the circular passage and the inwall of the dry core bodys of the B set in circular passage, the dry core body core bodys of B It is provided with least 3 wedgy passages.Realize DRV baffle casting to be cast by the way of two casees partings, also prevent The quiet sound check-valves baffle casting produces the generation of joint flash defect phenomenon, improves DRV baffle casting highly The dimensional accuracy in direction;Also reduce DRV baffle casting die manufacture difficulty, shorten DRV baffle The casting die manufacturing cycle is long, easy operation, productivity ratio are high, moreover it is possible to be suitable for the production of sand mo(u)ld frame, horizontal line and vertical line.
