Abstract
The invention relates to the field of material shaping, in particular to an asymmetric die and a die release method. The asymmetric die comprises a movable die body and a fixed die body, wherein the movable die body is connected with a press through a sliding block; the fixed die body is installed on a worktable; through motion of the sliding block, the movable die body and the fixed die body can be combined and separated; at least one of the movable die body and the fixed die body is provided with a material containing groove. The asymmetric die is simple in structure, easy to manufacture, easy and convenient to operate during use and capable of effectively avoiding accidental die sticking of die forgings, especially asymmetric die forgings, thereby greatly improving production efficiency.
Description
Technical field
The present invention relates to forming materials manufacture field, be specifically related to asymmetrical molds and release method.
Background technology
Forging part due to machine-finish allowance little, production efficiency is high, and interior tissue is even, and form and dimensional precision is high and be widely used in all trades and professions.In the forging process of forging part particularly asymmetric point of forging part; due to the difference of material friction, thermal expansion and deformation characteristic; forging is usually surprisingly trapped in dynamic model or cover half; and cannot according to the set stripping means demoulding; in this case usually need dismounting and refitting mould even to destroy forging, cause inconvenience to actual production process, for some large-scale forging parts; there is this kind of situation and have a strong impact on production efficiency especially, cause heavy economic losses.
Summary of the invention
In order to solve the problem, the invention provides a kind of mould structure simple, be easy to manufacture, and in use simple to operate, the accident that can avoid forging part particularly dissymmetrical die forging embraces mould phenomenon, substantially increases asymmetrical molds and the release method of forging production efficiency.
Asymmetrical molds of the present invention, comprises dynamic model and cover half, and described dynamic model is connected with press slide, and cover half is installed on workbench, and dynamic model is realized and the matched moulds of cover half and die sinking by slide block movement, at least selects one to arrange capaciting material groove in described dynamic model and cover half.
Preferably, capaciting material groove is set to several, and is all symmetrical arranged about the central axis of place dynamic model or cover half.
Preferably, the center line of capaciting material groove all on the same cross section of mould, the central axis upright of described cross section and mould.
Preferably, capaciting material groove is projected as quadrangle on mould shaft cross section.
Preferably, capaciting material groove is arranged on the inner surface of dynamic model.
Preferably, capaciting material groove is arranged on the inner surface of cover half.
Asymmetrical molds release method comprises the following steps:
The first step, mould arranges some capaciting material grooves, and described capaciting material groove is a groove;
Second step, forging equipment is installed dynamic, the cover half of asymmetrical molds, by needing the blank of forging and stamping to be placed between dynamic model and cover half, carries out matched moulds forging and stamping;
3rd step, carries out parting after having forged and pressed, and now forging is subject to the obstruction of filling metal in capaciting material groove and is stranded in predetermined dynamic model or cover half;
4th step, forging demoulding, utilizes the ejecting force of press push rod that the metal of filling in capaciting material groove has been deformed forging demoulding.
The mould structure related in the present invention is simple, is easy to manufacture, and in use easy and simple to handle, the accident of forging part particularly dissymmetrical die forging effectively can be avoided to embrace mould phenomenon, greatly enhance productivity.
Accompanying drawing explanation
Fig. 1 is asymmetrical molds and release method schematic diagram;
Reference numeral: 1-dynamic model, 2-cover half, 3-forging, 4-capaciting material groove, 5-push rod, 6-cushion block.
Detailed description of the invention
Asymmetrical molds, comprise dynamic model 1 and cover half 2, described dynamic model 1 is connected with press slide, and cover half 2 is installed on workbench by cushion block 6, dynamic model 1 is realized and the matched moulds of cover half 2 and die sinking by the slide block movement of press, selects one and arrange capaciting material groove 4 in described dynamic model 1 and cover half 2.Capaciting material groove 4 is set to several, and is all symmetrical arranged about the central axis of place dynamic model 1 or cover half 2.Arrange when can ensure die sinking like this, forging can be stranded in predetermined dynamic model 1 or cover half 2, the center line of capaciting material groove 4 all on the same cross section of mould, the central axis upright of described cross section and mould.Capaciting material groove 4 is projected as quadrangle on mould shaft cross section.Capaciting material groove 4 can be arranged on the inner surface of dynamic model 1, and capaciting material groove 4 also can be arranged on the inner surface of cover half 2.
Asymmetrical molds release method comprises the following steps: the first step, and mould arranges some capaciting material grooves 4, and described capaciting material groove 4 is a groove; Second step, forging equipment is installed dynamic, the cover half 1,2 of asymmetrical molds, by needing the blank of forging and stamping to be placed between dynamic model 1 and cover half 2, carries out matched moulds forging and stamping; 3rd step, carries out parting after having forged and pressed, and now forging is subject to the obstruction of filling metal in capaciting material groove 4 and is stranded in predetermined dynamic model 1 or cover half 2; 4th step, forging demoulding, utilizes the ejecting force of press push rod 5 that the metal of filling in capaciting material groove 4 has been deformed forging demoulding.
