Description
Technical field
The utility model relates to a kind of mold ejection mechanism.
Background technology
At present, the secondary ejecting mechanism of the mold ejection mechanism of prior art comprises top board for the first time, top board and limit lock catch for the second time, limit lock catch is arranged on for the first time top board and for the second time between top board, top board is used for the moving platen on the counterdie of top for the first time, under the effect of limit lock catch, in the time ejecting, just started for the first time top board moves upward with top board for the second time simultaneously, until when top board is limited for the first time, moving platen is positioned at limes superiors position, under the continuation effect of push rod thrust, the locking bar of limit lock catch and snap close are thrown off, top board continues to move upward until ejecting product for the second time, but limit lock catch and position-limit mechanism are all arranged in the die holder of counterdie, the volume that this has just increased counterdie, has increased the preparation cost of mould, and installation and maintenance all needs die holder to take apart and just can carry out afterwards, therefore installation and maintenance bothers, efficiency is lower, makes the cost of installation and maintenance higher, first die sinking simultaneously, the more whole process of Double-ejection is longer, and then cause the production cycle of mould longer, production efficiency is lower.
Utility model content
The utility model provides one can reduce die cost for above problem, and installation and maintenance is easier and can shorten production cycle of mould, improves the mold ejection mechanism of mould production efficiency.
The utility model overcomes the above problems technical scheme used: provide a kind of it comprise upper die and lower die and limit lock catch, described patrix is connected with counterdie, described counterdie is provided with moving platen, described limit lock catch is between patrix and moving platen.
Adopt after above structure, compared with prior art, the utility model is because limit lock catch is between patrix and moving platen, in the time of die sinking, patrix is first opened, in the time that patrix moves up the distance of cavity depth, under the effect of limit lock catch, patrix continues to move up and will drive moving platen to move up, in the time that moving platen moves to limes superiors position, two parts of limit lock catch separately, now the top board in counterdie gets final product work, product is ejected, and when product ejects, patrix is motion die sinking position place also, now product can be taken out, thereby complete whole die sinking process, therefore two top boards need not be set again, also save the position-limit mechanism of original top board, can also shorten the spacing between top board and counterdie simultaneously, the volume of die shoe is significantly reduced, reduce the preparation cost of mould, and limit lock catch is arranged on the side of mould, when installing and safeguarding, do not need other parts of mould to dismantle, make installation and maintenance easy, efficiency is also higher, and then reduces the cost of installation and maintenance, and because of the hypotelorism between top board and counterdie, the final stage top board of patrix motion starts to eject work, has significantly shortened opening period, and then shortens the production cycle of mould, improves the production efficiency of mould.Therefore the utlity model has and can reduce die cost, installation and maintenance is easier and can shorten production cycle of mould, improves the feature of mould production efficiency.
As improvement, described limit lock catch comprises locking bar and snap close, and described locking bar one end is fixedly connected with patrix, and described snap close is fixedly connected on moving platen, and the locking bar other end is connected with snap close; After arranging like this, when patrix motion, the kinetic stability of locking bar is better, and after die sinking, locking bar does not affect the normal pickup work of workman, can enhance productivity, and reduces production costs, and the structure of limit lock catch is simpler, and parts are less, can further reduce equipment cost.
As further improvement, described snap close comprises pressing plate, described pressing plate is fixedly connected on moving platen, the width of described pressing plate and moving platen binding face is provided with locking bar chute, the described locking bar other end is slidably connected in locking bar chute, on two sidewalls of described locking bar chute, be equipped with through hole, and the axis of the through hole on two sidewalls of locking bar chute is on same straight line, described through hole is provided with steel ball from inside to outside successively, spring and stop screw, through hole is less than the diameter of steel ball and is greater than the radius of steel ball at the diameter of locking bar chute wall upper shed, steel ball has part to be positioned at locking bar chute, described locking bar both sides are provided with steel ball and are positioned at the groove that the part of locking bar chute coordinates, the length that groove extends along length of locking rod direction equals the degree of depth of patrix die cavity, the snap close parts of this structure are less, and structure is simpler, and the reliability of use is better, and versatility is stronger, can do standardized production, and then further reduce production costs.
As further improving, described both sides, locking bar other end end are provided with chamfering or rounding again; After chamfering or rounding arrange, make locking bar be easier to be inserted between two steel balls, therefore it is more smooth and easy to reset, be not prone to locking bar stamp on steel ball and the problem that causes patrix to reset makes stability in use of the present utility model and dependability all better.
