Abstract
The invention discloses a stamping die facilitating die releasing. The die is used for stamping a part (4), a puncher pin matched with a lower die (2) is arranged on an upper die (1), a pressing plate (3) is arranged on the lower portion of the upper die (1), a lifting table (5) is arranged on the upper portion of the lower die (2), the opposite faces of the pressing plate (3) and the lifting table (5) are respectively and symmetrically provided with at least one groove (6), and compression springs (7) are arranged in the grooves (6) respectively. The compression springs are arranged on the pressing plate and the lifting table of the die, after stamping forming is completed, the part can be ejected and is disengaged from the die, the good die releasing effect is achieved, manual die releasing is not required, the production safety is good, and efficiency is high. In the stamping process, the grooves can reserve a space for the compression springs, the pressing plate can still tightly compress the part on the lifting table, the stamping forming effect cannot be affected, the integrally-formed structure is adopted by the pressing plate, the puncher pin and the upper die, machining is convenient, and stability is good.
Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of diel of being convenient to the demoulding.
Background technology
Punch process in machining occupies an important position in the processing industry of national economy.Adopt Sheet Metal Forming Technology, have that precision is high, efficiency is high, quality is good, save material, low cost and other advantages.Diel, is in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press, is at room temperature, utilizes the mould being arranged on forcing press to exert pressure to material, makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product.Quality, production efficiency and the production cost etc. of stamping parts, have direct relation with the Design and manufacture of mould.The height of Design of Dies and manufacturing technology level, is one of important symbol of weighing a national product manufacture level height, is determining to a great extent the development ability of quality, benefit and the new product of product.
Existing diel, in the time that the contact area of upper and lower mould and part is larger, easily occurs that part is bonded in the situation of difficult drop-off on patrix or counterdie, need to manually depart from, and operational danger is large and part working (machining) efficiency is low.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of diel that utilizes Compress Spring to help the part demoulding is provided, stripping result is good, under the prerequisite that ensures part crudy, greatly improves production efficiency.
The object of the invention is to be achieved through the following technical solutions: be convenient to the diel of the demoulding, for punching parts, it comprises upper die and lower die, on patrix, be provided with the drift matching with counterdie, the bottom of described patrix is provided with the pressing plate for punching press flanging, the top of counterdie is provided with the platform of lifting for lifting part, described pressing plate, lifts the one side that platform is relative and is all symmetrically arranged with at least one groove, is respectively arranged with the Compress Spring for helping the part demoulding in groove.
The shortest length of described Compress Spring compression is less than or equal to the degree of depth of groove.
The former length of described Compress Spring is greater than the degree of depth of groove.
Described pressing plate, drift and patrix adopt integrated molding structure.
The invention has the beneficial effects as follows:
1) pressing plate of mould, lift and on platform, be provided with Compress Spring, can complete after punch forming part is ejected, break away from moulds, reach good stripping result, without the artificial demoulding, production security is good and efficiency is high;
2) in punching course, groove can be the reserved space of Compress Spring, and pressing plate still can closely be pressed in part and lift on platform, can not affect punch forming effect;
3) pressing plate, drift and patrix adopt integrated molding structure, simple in structure, easy to process and have good stability, and are difficult for occurring deformation.
Brief description of the drawings
Fig. 1 is that part is pressed in disengaging pressing plate and lifts the structural representation between platform;
Fig. 2 has been the structural representation of the demoulding after die cut;
Fig. 3 is the structural representation taking out after part;
In figure, 1-patrix, 2-counterdie, 3-pressing plate, 4-part, 5-lifts platform, 6-groove, 7-Compress Spring.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, Figure 2, Figure 3 shows, be convenient to the diel of the demoulding, for punching parts 4, it comprises patrix 1 and counterdie 2, on patrix 1, be provided with the drift matching with counterdie 2, the bottom of described patrix 1 is provided with the pressing plate 3 for punching press flanging, and the top of counterdie 2 is provided with lifts platform 5 for what lift part 4, described pressing plate 3, lift the one side that platform 5 is relative and be all symmetrically arranged with at least one groove 6, in groove 6, be respectively arranged with the Compress Spring 7 for helping part 4 demouldings.The present embodiment center platen 3, lift the every side of platform 5 groove 6 is all only set, certainly, pressing plate 3, lift the every side of platform 5 two grooves 6 or more also can be set, if the degree of depth of bilateral symmetry and groove 6, the Compress Spring 7 placed identical, ensure part 4 horizontal positioned.
The shortest length that described Compress Spring 7 compresses is less than or equal to the degree of depth of groove 6, thereby avoids cannot continuing to have moved downward punch forming because Compress Spring 7 has been compressed to the shortest patrix 1 that causes.
The former length of described Compress Spring 7 is greater than the degree of depth of groove 6, thereby ensures that Compress Spring 7 can eject part 4, depart from pressing plate 3 and lift platform 5 under the effect of restoring force.
As preferably, the present embodiment center platen 3, drift and patrix 1 adopt integrated molding structure.
Figure 1 shows that patrix 1 is depressed into lowermost end, part 4 is pressed in and departs from pressing plate 3 and lift the structural representation between platform 5; Figure 2 shows that after die cut, patrix 1 lifting, part 4 completes the structural representation of the demoulding under the effect of Compress Spring 7; Figure 3 shows that the mould structure schematic diagram taking out after part 4, Compress Spring 7 is fixed on respectively pressing plate 3 or lifts on platform 5.
The above is only the preferred embodiment of the present invention, be to be understood that the present invention is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not depart from the spirit and scope of the present invention, all should be in the protection domain of claims of the present invention.
