The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The following describes in detail the strong-release delayed ejection mechanism 100 according to an embodiment of the present invention with reference to the drawings.
As shown in fig. 1 to 2, the strong-release delayed ejection mechanism 100 according to the embodiment of the present invention includes: a base plate 10, a pusher plate 20, a needle plate 30, and ejector pins 40.
Specifically, the push plate 20 is disposed on one side of the bottom plate 10, a sinking groove 21 is disposed at one end of the push plate 20 facing away from the bottom plate 10, the needle plate 30 is disposed on one side of the push plate 20 facing away from the bottom plate 10, a first mounting hole penetrating along the thickness direction of the needle plate 30 and corresponding to the sinking groove 21 is disposed on the needle plate 30, a strong-disengaging space is defined between one end of the thimble 40 passing through the first mounting hole and the bottom wall of the sinking groove 21, and the other end of the thimble 40 extends into the movable mold core 50.
In other words, according to the embodiment of the present invention, the bottom plate 10 is fixed to the bottom end of the whole mechanism. The push plate 20 is arranged on one side of the bottom plate 10 in parallel, and a sinking groove 21 is arranged at one end of the push plate 20 opposite to the direction of the bottom plate 10. The side of the push plate 20 opposite to the bottom plate 10 is provided with a needle plate 30, a first mounting hole is formed in the needle plate 30, one end of the thimble 40 can penetrate through the first mounting hole, and the other end of the thimble 40 can extend into the movable mold core 50.
It should be noted that a forced-disengaging space is defined between the tail of the end of the thimble 40 penetrating into the first mounting hole and the bottom wall of the sinking groove 21, when the push plate 20 moves towards the moving core 50, the needle plate 30 is driven to move, at this time, the end of the thimble 40 extending into the moving core 50 is fixed, and the other end of the thimble enters the forced-disengaging space. Since the thimble 40 is not supported at this time, one end of the thimble 40 extending into the movable mold core 50 moves downward along with the thimble, thereby realizing forced demoulding. When the push plate 20 continues to move towards the moving mold core 50, the ejector pin 40 falls into the sinking groove 21 and then continues to move along with the push plate 20, so as to eject the product.
Therefore, according to the utility model discloses according to the time delay ejection mechanism 100 is taken off by force, through combining together bottom plate 10, push pedal 20, faller 30 and thimble 40, the thimble can fall into smoothly and take off the empty space of keeping away by force, realizes taking off by force in the driven mould benevolence 50 to guarantee that the product can the drawing of patterns smoothly, practice thrift the usage space of mould.
According to the utility model discloses an embodiment, forcefully take off time delay ejection mechanism 100 still includes: and the elastic piece 60, wherein the elastic piece 60 is arranged between one end of the thimble 40 and the push plate 20. By providing the elastic member 60 between the one end of the thimble 40 and the push plate 20, the thimble 40 can be restored to the original position without an external force.
According to the utility model discloses an embodiment is equipped with the second mounting hole that link up along its thickness direction on the push pedal 20, and heavy groove 21 forms to the heavy groove of annular along the circumference extension of second mounting hole, and thimble 40's one end is equipped with along its axially extended locating hole, and the time delay ejection mechanism 100 of taking off by force still includes: the cushion block 70 is arranged on one side of the bottom plate 10 adjacent to the position of the movable die core 50, the cushion block 70 penetrates through the second mounting hole and extends into the annular sinking groove, a forced-disengaging clearance space is formed between the cushion block 70 and the wall surface of the annular sinking groove, one end of the elastic piece 60 is connected with the cushion block 70, and the other end of the elastic piece 60 is located in the positioning hole. Therefore, after the injection molding of the mold is completed, the ejector pin 40 performs forced releasing of the product through the forced releasing empty space when the ejector pin 40 moves in the push plate 20. When the ejector pin 40 is completely retracted to the annular sinking groove, the ejector pin 40 moves along with the push plate 20, so that the ejector pin 40 ejects the product.
Alternatively, the other end of the elastic member 60 is a free end. That is, the distance between the elastic element 60 and the thimble 40 can be designed according to the actual situation, so as to satisfy the requirement of compact structure and realize the function of resetting.
Preferably, the elastic member 60 is a spring. The spring has good flexibility and can better cooperate with the thimble 40 to move.
In some embodiments of the present invention, the radial dimension of one end of the thimble 40 is greater than the radial dimension of the other end of the thimble 40. The radial dimension of the end of the thimble 40 extending into the needle plate 30 needs to be larger than the radial dimension of the end of the thimble 40 extending into the movable die core 50, and the end with the larger dimension can be matched with the elastic element 60 and the cushion block 70 to complete the actions of ejection and reset.
According to an embodiment of the present invention, one end of the thimble 40 is greater than the depth of the first mounting hole along its axial length. That is, a portion of the thimble 40 is located outside the first mounting hole, so that the subsequent forcible releasing and ejecting actions of the thimble 40 can be better realized.
Optionally, one end of the spacer 70 is connected to the base plate 10, and the other end of the spacer 70 is flush with the end of the push plate 20 adjacent to the movable mold core 50. The height of the cushion block 70 is limited, so that the purpose of saving the use space of the die is achieved.
According to the utility model discloses an embodiment, forcefully take off time delay ejection mechanism 100 still includes: and fixing screws 80, wherein the cushion block 70 is fixed on the bottom plate 10 by the fixing screws 80. The cushion block 70 is fixed by the fixing screw 80, so that the mounting process is simple and convenient, and the looseness is not easy to occur.
In some embodiments of the present invention, the head of the set screw 80 extends out of the spacer 70 and into the positioning hole. The part of the fixing screw 80 extending out of the cushion block 70 is used for placing the elastic element 60, thereby ensuring that the internal space of the forced release delay ejection mechanism 100 is reasonably utilized.
To sum up, according to the utility model discloses according to delayed ejection mechanism 100 of forced demoulding, through combining together bottom plate 10, push pedal 20, faller 30 and thimble 40, thimble 40 can fall into the space of avoiding taking off by force smoothly, realizes taking off by force in the slave mould benevolence 50, and follow-up when thimble 40 falls into heavy groove 21 completely, can follow up push pedal 20 and continue the motion with faller 30 to ejecting product guarantees that the product can be demolded smoothly, practices thrift the usage space of mould.
