Description
Technical field
The utility model belongs to dynamo-electric manufacturing field, particularly a kind of apparatus for pouring of explosion lid.
Background technology
The explosion lid is a part on the M type load ratio bridging switch, and this part is a key component.Mainly be that load ratio bridging switch is played the safeguard protection effect, namely when the switch internal pressure surpassed 0.2MPa, the release pressure that pops was covered in explosion.This part has the sealing property requirement, but very little at breaking groove place wall thickness, and cast is prone to the pouring defect pin hole in producing, influences the product use.And being originally the sand mold cast, the frequent seepage of experiments of sealing performance, the qualification rate of product are 30-40% only, are difficult to satisfy user's production demand.
The utility model content
For overcoming above-mentioned defective, the technical problems to be solved in the utility model provides a kind of new apparatus for pouring, and this device changes traditional running gate system and reaches seal request.
A kind of apparatus for pouring of explosion lid, this apparatus for pouring comprise liftout plate, go up mold mounting plate, guide post, model steam vent, patrix, pouring piece, counterdie, knock-pin; Liftout plate is positioned at the top of whole apparatus for pouring, and last mold mounting plate is provided with steam vent at patrix between liftout plate and patrix; One end of guide post is fixed on the patrix, and the other end passes mold mounting plate and is connected with liftout plate; Upper die and lower die are a tight fit in together, are provided with pouring piece at counterdie, and the shape of pouring piece is consistent with the shape of die cavity.One end of knock-pin is positioned on the patrix, and the other end was worn mold mounting plate and is connected with liftout plate; Be provided with the sprue gate at counterdie.
Steam vent can be generally 4～8 as required.
The product that adopts the utility model apparatus for pouring to produce, qualification rate has brought up to 90%, can satisfy user's production demand, reduces production costs greatly again, has improved market and has striven power unexpectedly.
Description of drawings
Fig. 1 is the structural representation of explosion lid;
Fig. 2 is the front view of the utility model apparatus for pouring;
Fig. 3 is the vertical view of the utility model apparatus for pouring.
The specific embodiment
Fig. 1 is the structural representation of explosion lid, and the A place is the weak link of explosion lid among the figure, and the groove wall thickness only is 0.5 ㎜.The present invention through constantly practice, has worked out a kind of new pouring procedure in order to satisfy the specification requirement of explosion lid, and this method adopts the order of solidifying of control product, changes the sealing property requirement that traditional sand casting method reaches the explosion lid.
The utility model has designed a kind of explosion lid apparatus for pouring, and this device changes original sand mold cast into the punching block casting mold, increases pressure in the forming process, crystallization under pressure, and the nucleus that forms pin hole can not be grown up, and has therefore eliminated pin hole.
As Fig. 2, shown in Figure 3, a kind of apparatus for pouring of explosion lid comprises liftout plate 1, goes up mold mounting plate 2, guide post 3, model steam vent 4, patrix 5, pouring piece 6, counterdie 7, knock-pin 8.Liftout plate 1 is positioned at the top of whole apparatus for pouring, and last mold mounting plate 2 is provided with steam vent 4 at patrix 5 between liftout plate 1 and patrix 5; One end of guide post 3 is fixed on the patrix 5, and the other end passes mold mounting plate 2 and is connected with liftout plate 1.Patrix 5 and counterdie 7 are a tight fit in together, are provided with pouring piece 6 between patrix 5 and counterdie 7, and the shape of pouring piece 6 is consistent with the shape of die cavity.One end of knock-pin 8 is positioned on the patrix 5, and the other end was worn mold mounting plate 2 and is connected with liftout plate 1.Steam vent 4 can be generally 4～8 as required.Be provided with the sprue gate at counterdie 7.
The utility model apparatus for pouring solidifies order with control, allows the cast gate final set, and pouring piece 6 is well compensated, the density height of product like this, and sealing property is guaranteed, and has satisfied user's instructions for use.Adopt the utility model apparatus for pouring to improve product percent of pass greatly, economic benefit is improved.
