Description
Technical field
The utility model relates to a kind of ejecting mechanism of mould, especially relates to a kind of slidingtype spring punch die ejecting mechanism.
Background technology
At present; often can use the cold-heading technology in machine industry; and the spring punch die in the cold-heading technology is widely used; there is no material returned rod in this spring punch die as shown in Figure 1; and forming hole 9 bottoms equate with the total length L 6 of thimble 2 to the height L5 of the bottom of alloy punch die, so thimble 2 can not eject workpiece.Adopt spring punch die jumping-up that buckling and folding line defect can not occur, can also increase upsetting length, and upsetting length can be brought up to 8 times of diameter left and right, yet, higher and when the workpiece of straight section is arranged at upsetting head processed, or this product bar section is shorter, all can has containing material phenomenon (being commonly called as band material phenomenon) and cause and can't normally produce at the spring punch die; In order to avoid the appearance containing the material phenomenon, be generally all that forming hole is processed into to the forming hole with pattern draft, be made in like this in subsequent handling and will revised or reprocess product, must increase corresponding operation.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of can increase upsetting length and not there will be containing the material phenomenon slidingtype spring punch die ejecting mechanism.
The technical scheme in the invention for solving the technical problem is: a kind of slidingtype spring punch die ejecting mechanism, comprise die sleeve, one side end face of die sleeve is provided with backing plate, in die sleeve, backing plate is provided with spring pad, spring pad is provided with spring, described spring pad comprises bottom big column and top small column, small column is positioned at spring inner, the spring pad step surface that big column and small column form is placed spring end face, the top of spring is provided with the alloy punch die, the alloy punch die is provided with the punch die step, die sleeve inside is provided with the die sleeve step, punch die step and die sleeve step are used in conjunction with, be provided with forming hole on the alloy punch die, the centre hole that is provided with thimble in forming hole inside, the inside of alloy punch die and places thimble, centre hole is counter sink, the countersunk head degree of depth of centre hole is consistent with the height of thimble head, be provided with material returned rod hole in the middle of described spring pad, material returned rod is provided with material returned rod in hole, backing plate inside below material returned rod hole is provided with excellent hole, top, push up in excellent hole and be provided with the top rod.
In order to eject smoothly workpiece, described thimble total length equates with the height of alloy punch die.
For when the matched moulds, top end face that can thimble is just in the forming hole bottom, and described material returned rod hole is counter sink, and the difference of the height of the height of its countersunk head and material returned club head equates with the height of forming hole.
The beneficial effects of the utility model are: after having adopted said structure, all advantages that can retain the spring punch die, and because adopted material returned bar structure to solve the shortcoming containing material of spring punch die, do not had pattern draft not there will be subsequent correction or rework process, the rate of can reducing the number of rejects and seconds, improve the quality of product and the speed of production of product.
