Description
Technical field
The utility model belongs to die casting field, particularly relates to a kind of compression mod without the ejecting mechanism of the push rod marking.
Background technology
At present, in all kinds of die castings, have a class to have larger area and shape matching rule, the surface of these foundry goods has not allowed to eject the marking, and requires foundry goods just can meet matching requirements without processing.The ejecting mechanism of the compression mod of prior art is all to adopt moving push pedal that foundry goods is ejected, but cinder ladle, running channel and foundry goods during moving ejecting push plate, have been released simultaneously, cinder ladle, running channel and foundry goods are still embedded in push pedal like this, need the driven push pedal of workman's manual operations ability in addition to throw off, but operation is higher to operation requirements like this, on no person's foundry goods, easily there is the groove that cinder ladle or running channel produce after fracture when throwing off on foundry goods, thereby cause foundry goods to be scrapped; Or also easily on foundry goods, produce the marking, and then cause foundry goods to be scrapped.Therefore the compression mod of prior art exists without the ejecting mechanism of the push rod marking that to eject efficiency lower, and yield rate is lower, the long and higher problem of production cost of production cycle.
Utility model content
The utility model provides for above problem that a kind of to eject efficiency higher, and yield rate is higher, and the compression mod that the production cycle is shorter and production cost is lower is without the ejecting mechanism of the push rod marking.
The utility model overcomes the above problems technical scheme used: provide a kind of and have the compression mod of following structure without the ejecting mechanism of the push rod marking, it comprises dynamic model, be embedded in the dynamic model meat in dynamic model, be positioned at the push pedal of dynamic model meat, push pedal fore-set and the top board being slidably connected with dynamic model, described push pedal fore-set one end is connected with push pedal, the push pedal fore-set other end is crossed dynamic model and is fixedly connected with top board with dynamic model meat, between described top board and dynamic model, be provided with for ejecting the secondary top board of cinder ladle, described secondary top board is provided with thimble, described thimble one end is fixed on secondary top board, thimble other end end face is crossed dynamic model, the die cavity wall that dynamic model meat is corresponding with cinder ladle in push pedal with push pedal is concordant.
Adopt after above structure, compared with prior art, the utility model is owing to being provided with for ejecting secondary top board and the thimble of cinder ladle, in knockout course in ejecting push plate foundry goods, under the effect of secondary top board and thimble, thimble ejects cinder ladle, thereby cinder ladle, running channel and foundry goods integral body are thrown off from push pedal, thimble only withstands on cinder ladle owing to ejecting, therefore can not injure foundry goods (being product), without the follow-up artificial demoulding, simple to operate, demoulding efficiency and yield rate are all higher, thereby reduce production costs; And eject after action completing, ejecting mechanism is returned to origin-location and can regenerates, and then shorten the production cycle, enhance productivity, reduce production costs.Therefore the utlity model has that to eject efficiency higher, yield rate is higher, the feature that the production cycle is shorter and production cost is lower.
As improvement, the plane of the described nearly top board of secondary top board is provided with the banking pin that prevents secondary top board and top board laminating, because if after secondary top board and top board laminating, under the effect of lubricating oil, between secondary top board and top board, easily produce mutual suction, and be difficult for separately, thereby ejecting mechanism cannot be resetted smoothly, and cause, produce to suspend, banking pin setting, makes no longer to produce between secondary top board and top board suction, guarantee that ejecting mechanism can reset, and then make the continuity of production better, enhance productivity, and reduce production costs.
As further improvement, described top board is provided with the acceleration mechanism that secondary top board is accelerated, after acceleration mechanism arranges, make thimble have larger impulsive force to cinder ladle, and then guarantee that cinder ladle, running channel and foundry goods integral body can once throw off from push pedal, otherwise easily occur that cinder ladle is bent, and running channel and foundry goods are also the situation of throwing off, and then assurance demoulding efficiency, can further improve production efficiency, and reduce production costs.
As further improving again, described acceleration mechanism comprises anti-piece, gag lever post, the first through hole on top board and the second through hole on secondary top board, in the middle of described anti-piece, by axle, be hinged in the first through hole, and anti-piece two ends all exceed the plane of the nearly secondary top board of top board, the second described through hole exceeds the one end in top board two ends over against anti-piece, the end, one end of described gag lever post is arranged in the second through hole, the other end of gag lever post is fixedly connected with dynamic model, the structure that this acceleration mechanism is pure machinery, simple in structure, preparation cost is lower, and structural stability and stability in use are all better, and then assurance demoulding efficiency.
As further improving again, on described axle, establish spacing collar spacing between anti-piece both sides and the first through hole hole wall, after spacing collar arranges, can prevent anti-piece both sides and the laminating of the first through hole hole wall, thereby there is the stagnant situation of living of anti-piece, guarantee the flexibility that anti-piece rotates, and then guarantee secondary top board acceleration effect, increase the utility model stability in use.
As further improving, the back stitching mechanism that described secondary top board is provided with on top board, existing back stitching mechanism structure is identical, back stitching mechanism can guarantee after arranging that secondary top board also can automatically reset, thereby the utility model can be produced continuously, shorten the production cycle, further improve production efficiency of the present utility model, and further reduce production costs.
