Abstract
The utility model relates to a pouring device of a flange disc. The pouring device mainly comprises an ejecting plate, an upper die, ejecting rods, an upper die corner, a lower die, a sprue and a positioning plate. The ejecting plate is located at the top of the whole pouring device. The positioning plate is located between the ejecting plate and the upper die. A retainer ring is located on the upper end of the upper die. One end of the ejecting rod is connected with the ejecting plate while the other end passes through the upper die. The upper die is matched with the lower die. A cavity for pouring a piece to be poured is arranged between the upper die and the lower die. The piece to be poured is consistent with the cavity in shape. The lower die is provided with a sprue. Eight ejecting rods are arranged. For the product processed by the pouring device provided by the utility model, the percent of pass reaches 85-90%, so that not only is the production demand of users met, but also the production cost is greatly lowered.
Description
Technical field
The utility model belongs to dynamo-electric manufacturing field, particularly a kind of apparatus for pouring of ring flange.
Background technology
A ring flange is arranged on the V-type load ratio bridging switch, and this ring flange is a key component of V-type load ratio bridging switch.This part is had relatively high expectations to sealing property, but wall thickness is larger, is prone to pin hole, the defective such as loose in casting process, has a strong impact on product and uses.Owing to being originally sand casting, the frequent seepage of experiments of sealing performance, the qualification rate of product are only 25～30%, are difficult to satisfy user's Production requirement.Because the annual consumption of this ring flange is more than 1000, therefore has market value.
The utility model content
For overcoming defects, the technical problems to be solved in the utility model is to provide a kind of apparatus for pouring of new ring flange, and this installs to change traditional running gate system and reaches seal request.
A kind of apparatus for pouring of ring flange, this apparatus for pouring mainly comprises: liftout plate, patrix, knock-pin, upper modular angle, counterdie, cast gate, location-plate; Liftout plate is positioned at the top of whole apparatus for pouring, and location-plate is between liftout plate and patrix; Upper modular angle is positioned at the top of patrix, and an end of knock-pin is connected with liftout plate, and the other end is connected with patrix; Patrix matches with counterdie, is provided with between upper die and lower die be used to the die cavity of pouring into a mould to be cast, and the shape of to be cast is consistent with the shape of die cavity; Counterdie is provided with cast gate.The quantity of knock-pin is 8
The product that adopts the utility model apparatus for pouring to process, qualification rate can reach 85～90%, can satisfy user's Production requirement, has reduced greatly again production cost.
Description of drawings
Fig. 1 is the structural representation of ring flange;
Fig. 2 is the utility model apparatus for pouring structural representation.
The specific embodiment
It is the structural representation of ring flange as Fig. 1, traditional sand mould casting method easily makes product pin hole occur and shrinkage porosite is waited until phenomenon, the purpose of this utility model is to design a kind of Novel pouring device, reach seal request with the solidification sequence of controlling product, reduce as far as possible the generation of pin hole and shrinkage porosite phenomenon.
As shown in Figure 2, a kind of apparatus for pouring of ring flange mainly comprises: liftout plate 1, patrix 2, knock-pin 3, upper modular angle 4, counterdie 6, cast gate 7, location-plate 8.Liftout plate 1 is positioned at the top of whole apparatus for pouring, and location-plate 8 is between liftout plate 1 and patrix 2; Upper modular angle 4 is positioned at the top of patrix 2, and an end of knock-pin 3 is connected with liftout plate 1, and the other end is connected with patrix 2; Patrix 2 matches with counterdie 6, is provided be used to the die cavity of pouring into a mould to be cast 5 between patrix 2 and counterdie 6, and the shape of to be cast 5 is consistent with the shape of die cavity.Knock-pin 3 can be generally 8 as required.Counterdie 6 is provided with cast gate 7.
The utility model adopts a kind of new apparatus for pouring, changes original sand casting into the punching block casting mold, increases pressure in forming process, crystallization under pressure, and the nucleus that forms pin hole can not be grown up, and has eliminated pin hole.Control simultaneously the solidification sequence of pouring piece 5, allow the cast gate final set, allow pouring piece 5 well be compensated, the density of the product of producing is high, and sealing property is guaranteed, thereby has improved product percent of pass, and economic benefit is improved.
