Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of diel 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 be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with the Design and manufacture of mould.The height of Mould design and manufacturing technical merit, is one of important symbol of a measurement national product manufacture level height, decides the development ability of the quality of product, benefit and new product to a great extent.
Existing diel, when 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, needs manually to 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, provide a kind of diel utilizing Compress Spring to help part removal, stripping result is good, greatly improves production efficiency under the prerequisite ensureing part crudy.
The object of the invention is to be achieved through the following technical solutions: the diel being convenient to the demoulding, for punching parts, it comprises upper die and lower die, patrix is provided with the drift matched with counterdie, the bottom of described patrix is provided with the pressing plate for punching press flanging, the top of counterdie is provided with lifts platform for what lift part, described pressing plate, lifts the relative one side of platform and is all symmetrically arranged with at least one groove, is respectively arranged with the Compress Spring for helping part removal 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) mould pressing plate, lift on platform and be provided with Compress Spring, can be ejected by part after completing punch forming, break away from moulds, reach good stripping result, without the need to 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 part still can closely be pressed in by pressing plate to be lifted on platform, can not affect punch forming effect;
3) pressing plate, drift and patrix adopt integrated molding structure, and structure is simple, easy to process and have good stability, and not easily deformation occur.
Accompanying drawing explanation
Fig. 1 is that part is pressed in the structural representation departing from pressing plate and lift between platform;
Fig. 2 has been the structural representation of the demoulding after die cut;
Fig. 3 is the structural representation after taking out 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, patrix 1 is provided with the drift matched 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, lifting the relative one side of platform 5 and be all symmetrically arranged with at least one groove 6, in groove 6, being respectively arranged with the Compress Spring 7 for helping part 4 demoulding.The present embodiment center platen 3, lift platform 5 every side a groove 6 is all only set, certainly, pressing plate 3, lift the every side of platform 5 also two grooves 6 or more can be set, if bilateral symmetry and the degree of depth of 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, thus avoids because Compress Spring 7 has been compressed to the shortest and cause patrix 1 cannot continue to have moved downward punch forming.
The former length of described Compress Spring 7 is greater than the degree of depth of groove 6, thus ensures that part 4 can eject, departs from pressing plate 3 and lift platform 5 by Compress Spring 7 under the effect of restoring force.
As preferably, the present embodiment center platen 3, drift and patrix 1 adopts integrated molding structure.
Figure 1 shows that patrix 1 is depressed into lowermost end, part 4 is pressed in the structural representation departing from pressing plate 3 and lift between platform 5; After having Figure 2 shows that 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 after taking out part 4, Compress Spring 7 is fixed on pressing plate 3 respectively 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 the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
