Abstract
The utility model discloses an ejector pin is balanced structure for to multi -station die structure, including a lower mould, still include the tensile ejector pin with lower mould jack -up, wherein, still include to contact other molding cavity's of jack -up lower mould parallel ejector pin simultaneously with the lower mould, adopt the utility model discloses but the molding cavity of other inoperatives of lower mould of prior art does not cause the atress uneven owing to there is the ejector pin to support easily, can damage mould structure's problem even.
Description
Technical field
This utility model relates to diel field, a kind of push rod balanced structure for multiple station die lamps structure.
Background technology
In diel field of today, for improving production efficiency, reduce production cost, for the part that some shape and structures less complex parts are bigger, progressive die cost is the highest, waste again factory resources by the single working procedure processing of large tonnage pressing machine in exploitation, the mould of the now artificial feeding of a multi-cavity mold occurs as soon as, so, one backhaul action of forcing press just can process multiple operation simultaneously, mould development cost greatly reduces, factory saves more board and makees more part, and production efficiency also effectively improves.But the lower push rod of big board is uniform operational, or point two parts uniform operational, but the most all die cavities of mould of this kind of a multi-cavity mold are required for push rod work, but stretching process just needs push rod, other are not required to use lower push rod so easily causing by force unbalance, even can damage lathe.At this moment spring or nitrogen spring can only be used as binder pressure source at stretching process, but two kinds of pressure sources occur that a problem pressure not or is accelerated add cost for being reached certain pressure increase pressure source the most simultaneously.
Therefore, prior art has yet to be improved and developed.
Utility model content
The purpose of this utility model is to provide a kind of push rod balanced structure for multiple station die lamps structure, to solve the following problem of prior art: the most all die cavities of mould of a multi-cavity mold are required for work, when stretching process, the lower mold of the cavity portion of work is typically needed with stretching push rod jack-up, the molding cavity of other inoperatives of lower mold then can easily cause by force unbalance owing to not having push rod to support, even can mold damage structure.
The technical solution of the utility model is as follows:
A kind of push rod balanced structure for multiple station die lamps structure, including a lower mold, also includes the stretching push rod of lower mold jack-up, wherein, also includes contacting the parallel push rod of jack-up other molding cavities of lower mold the most simultaneously with lower mold.
The described push rod balanced structure for multiple station die lamps structure, wherein, described parallel push rod is column push rod.
The described push rod balanced structure for multiple station die lamps structure, wherein, described parallel push rod is provided with one with the bottom of stretching push rod and provides the board air cushion of lower mold described in upwards active force jack-up to parallel push rod and stretching push rod.
The described push rod balanced structure for multiple station die lamps structure, wherein, described parallel top pole stock matter is A3 steel or 45# steel.
The described push rod balanced structure for multiple station die lamps structure, wherein, described parallel top pole stock matter is alloy tool steel.
The described push rod balanced structure for multiple station die lamps structure, wherein, described parallel top pole stock matter is air cooling steel.
The beneficial effects of the utility model: this utility model is by providing a kind of push rod balanced structure for multiple station die lamps structure, air cushion is provided with inoperative molding cavity during balance post rod support stamping procedure, the molding cavity of other inoperatives of lower mold solving prior art easily causes by force unbalance owing to not having push rod to support, even can the problem of mold damage structure.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, this utility model is further described by the embodiment that develops simultaneously referring to the drawings.
Refering to Fig. 1, this utility model provides a kind of push rod balanced structure for multiple station die lamps structure, including a lower mold 5, also includes the stretching push rod 3 of lower mold 5 jack-up, wherein, also include contacting the parallel push rod 4 of other molding cavities of jack-up lower mold 5 the most simultaneously with lower mold 5.
In the present embodiment, described parallel push rod 4 is column push rod, is set to the form of column push rod similar with the shape and structure of stretching push rod 3, and the similar parts of two shape and structures play more preferable balanced action.
Further, described parallel push rod 4 is provided with one and provides the board air cushion 2 of lower mold 5 described in upwards active force jack-up to parallel push rod 4 and stretching push rod 3 with the bottom of stretching push rod 3, board air cushion 2 is a bullet apical organ, being promoted by air pressure in the present embodiment, parallel push rod 4 and stretching push rod 3 are provided power upwards to move it up by board air cushion 2.
Preferably, described parallel top pole stock matter is alloy tool steel.Alloy tool steel can apply multiple Technology for Heating Processing to carry out the improvement of performance, if Cr12 mould steel is after micronization processes, not only hardness, intensity increase, and toughness, impact resistance also can be substantially improved, parallel push rod 4 needs to bear the quality of lower mold, and the alloy tool steel after Overheating Treatment meets parallel top pole pair intensity and the requirement of hardness.
As another embodiment of the present utility model, described parallel push rod 4 material can be air cooling steel, and air cooling steel is the flame hardening material of non-convention, quenching wide ranges, quenching degree is good, and deformation rate is little, and air cooling steel can obtain high rigidity after Quenching Treatment and don't lose original toughness.
Certainly, due to cost considerations, parallel push rod 4 is used as the push rod operation use of parallel drawing, only produces parallel and stretching process push rod power, and material can also be common A3 steel or 45# steel.
Further, stuck in lower mold with lower mold friction for preventing, parallel push rod 4 also sets up a self-oiling guide bushing (not indicating in figure).
The following is work process of the present utility model:
Owing to mould has only done contact boss in the position (blank holder) needing push rod power when design, the most also include the position of parallel push rod.Workman stretches push rod according to push rod scattergram in the position placement specified, during work, the mandrel plate below forcing press is up lifted, the blank holder of stretching process is also followed to live in lift due to the effect of push rod power, the most parallel push rod is the most up lifted, when forcing press is down pressed, the upper mold of die drawn operation first contacts by the blank holder of board jack-up, blank holder down works until mould machines palikinesia on earth with parallel push rod simultaneously, and whole process does not produce offset loading force due to the lower push rod plate of the acting press of parallel push rod.
This utility model is by providing a kind of push rod balanced structure for multiple station die lamps structure, air cushion is provided with inoperative molding cavity during balance post rod support stamping procedure, the molding cavity of other inoperatives of lower mold solving prior art easily causes by force unbalance owing to not having push rod to support, even can the problem of mold damage structure.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these modifications and variations all should belong to the protection domain of this utility model claims.
