Abstract
The invention discloses an ejector rod balance structure specially used for a multi-station die structure. The ejector rod balance structure comprises a lower die, and further comprises a stretching ejector rod used for ejecting the lower die. The ejector rod balance structure further comprises parallel ejector rods which make contact with the lower die and eject other molding cavities of the lower die at the same time. Due to the adoption of the ejector rod balance structure, the problems that because in the prior art, other non-working molding cavities of the lower die are not supported by ejector rods, stress unbalance is likely to happen, even the die structure can be damaged are solved.
Description
Technical field
The present invention relates to diel field, in particular a kind of push rod balanced structure for multiple station die lamps structure.
Background technology
In diel field of today, for enhancing productivity, reduce production cost, for some shape and structures part that not too complex parts are larger, exploitation progressive die cost is very high, process by the single operation of large tonnage pressing machine and waste factory resources again, the mould of the now artificial feeding of a multi-cavity mold has just occurred, like this, a backhaul action of forcing press just can process multiple operation simultaneously, mould development cost reduces greatly, factory saves more board and makees more part, and production efficiency also effectively improves.But the lower push rod of large board is uniform operational, or point two parts uniform operational, but the mould of this kind of a multi-cavity mold not all die cavities all need push rod work, but stretching process just needs push rod, other do not need to use lower push rod so easily cause by force unbalance, even can damage lathe.At this moment spring or nitrogen spring can only be adopted as binder pressure source at stretching process, but two kinds of pressure sources occur that a problem pressure increases pressure source and accelerates and add cost not or for reaching certain pressure all simultaneously.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
The object of the present invention 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 mould of a multi-cavity mold is not that all die cavities all need work sometimes, when stretching process, general stretching push rod jack-up needs the counterdie of the cavity portion of work, the molding cavity of other inoperatives of counterdie then easily can cause by force unbalance owing to not having push rod to support, even can mold damage structure.
Technical scheme of the present invention is as follows:
For a push rod balanced structure for multiple station die lamps structure, comprise a counterdie, also comprise the stretching push rod of counterdie jack-up, wherein, also comprise the parallel push rod contacting also other molding cavities of jack-up counterdie simultaneously with counterdie.
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 and the bottom of stretching push rod are provided with one and provide upwards active force and the board air cushion of counterdie described in 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.
Beneficial effect of the present invention: the present invention 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 solving other inoperatives of counterdie of 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 object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
Consult Fig. 1, the invention provides a kind of push rod balanced structure for multiple station die lamps structure, comprise a counterdie 5, also comprise the stretching push rod 3 of counterdie 5 jack-up, wherein, the parallel push rod 4 contacting also other molding cavities of jack-up counterdie 5 simultaneously with counterdie 5 is also comprised.
In the present embodiment, described parallel push rod 4 is column push rod, and the form being set to column push rod is similar with the shape and structure of stretching push rod 3, and the similar parts of two shape and structures play better balanced action.
Further, described parallel push rod 4 and the bottom of stretching push rod 3 are provided with one and provide upwards active force and the board air cushion 2 of counterdie 5 described in jack-up to parallel push rod 4 and stretching push rod 3, board air cushion 2 is bullet apical organs, promoted by air pressure in the present embodiment, board air cushion 2 provides power upwards to make it move up to parallel push rod 4 and stretching push rod 3.
Preferably, described parallel top pole stock matter is alloy tool steel.Alloy tool steel can apply the improvement that multiple Technology for Heating Processing carries out performance, if Cr12 mould steel is after micronization processes, not only hardness, intensity increase, and toughness, impact resistance also can significantly promote, parallel push rod 4 needs the quality of bearing counterdie, and the alloy tool steel after Overheating Treatment meets the requirement of parallel top pole pair intensity and hardness.
As another embodiment of the present invention, 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 and don't lose original toughness after Quenching Treatment.
Certainly, for the consideration of cost, parallel push rod 4 is used as the push rod operation use of parallel drawing, and only produce power that is parallel and stretching process push rod, material also can be common A3 steel or 45# steel.
Further, stuck at counterdie for preventing from rubbing with counterdie, parallel push rod 4 is also arranged a self-oiling guide bushing (not indicating in figure).
Below the course of work of the present invention:
Due to mould when designing only needing the position of push rod power (blank holder) to do contact boss, certainly also comprise the position of parallel push rod.Workman places stretching push rod according to push rod distribution map in the position of specifying, mandrel plate during work 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, meanwhile parallel push rod is also up lifted, forcing press first contacts by the blank holder of board jack-up toward the patrix of die drawn operation when pressing down, blank holder and parallel push rod down work until mould machines repetitive operation on earth 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.
The present invention 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 solving other inoperatives of counterdie of 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 invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
