Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
In figure, top board 1; Fixed head 2; Backing plate 3; Upper inclined guide groove 31; Thimble panel 4; Ejector Retainer Plate 5; Lower shoe 6; Contour screw 7; Male die core 8; Centre hole 9; Middle shoulder thimble 10; Spring 11; Slide block 12; Lower inclined guide groove 121; Angle Pin 13; Headspace breach 14; End face 15; Put down to portion 151; Oblique portion 152; Injecting products 16.
As Fig. 1, shown in Fig. 2 and Fig. 3, this slide block differential type mould emptier, from top to bottom comprise top board 1 successively, fixed head 2, backing plate 3, thimble panel 4, Ejector Retainer Plate 5 and lower shoe 6, contour screw 7 is provided with between thimble panel 4 and backing plate 3, contour screw 7 is connected with thimble panel 4 with one end, the other end is connected with top board 1 through backing plate 3 and fixed head 2 are rear simultaneously, centre position is provided with male die core 8 with fixed head 2, injecting products 16 is positioned on male die core 8, fixed head 2 and backing plate 3 fixing after for fixing male die core 8 position, male die core 8 offers centre hole 9, thimble 10 is takeed in being provided with in centre hole 9, backing plate 3 and fixed head 2 are run through in middle shoulder thimble 10 lower end simultaneously, spring 11 is provided with in backing plate 3, spring 11 to be set on middle shoulder thimble 10 and to be used for withstanding middle shoulder thimble 10, take on thimble 10 in such convenience upwards to reply after ejecting product.
The maximum innovation of the present invention is provided with differential type demoulding assembly between backing plate 3 and thimble panel 4, the lower end of middle shoulder thimble 10 to be acted on differential type demoulding assembly and is upwards ejected the injecting products 16 of male die core 8 by differential type demoulding assembly, here differential type demoulding assembly comprises slide block 12 and Angle Pin 13, top, middle shoulder thimble 10 lower end is pressed on slide block 12, slide block 12 is arranged on thimble panel 4, slide block 12 offers lower inclined guide groove 121, backing plate 3 offers inclined guide groove 31, the two ends of Angle Pin 13 are through inclined guide groove 31 and lower inclined guide groove 121, the position of Angle Pin 13 just fixed by such backing plate 3 and thimble panel 4, here the Main Function of Angle Pin 13 is effects slide block 12 being played to guiding, because the direction of Angle Pin 13 pairs of slide blocks 12 limits when moving upward during the demoulding, make slide block 12 just to left movement like this, thus thimble lower end active position is changed, realize product to eject, thimble panel 4 and Ejector Retainer Plate 5 offer the headspace breach 14 moved for Angle Pin 13, facilitate the motion of Angle Pin 13 lower end like this, slide block 12 has the end face 15 matched with the lower end of middle shoulder thimble 10, end face 15 is divided into puts down to portion 151 and oblique portion 152, take on thimble 10 lower end movement locus in during die sinking and move to oblique portion 152 by end face 15 is flat to portion 151, here when slide block 12 moves to oblique portion 152 by end face 15 is flat to portion 151 to thimble middle during left movement, also middle thimble position is just equivalent to back down, thus upwards ejecting product.
The operation acts principle of this slide block differential type mould emptier is as follows:
1, the first state (Fig. 1) after die sinking, thimble panel 4 and Ejector Retainer Plate 5 are under machinery ejects effect, top board 1 is driven to start to move with uniform velocity to diagram top together by contour screw 7, simultaneously, thimble panel 4 also drives slide block 12, middle shoulder thimble 10 to move together, start to move with uniform velocity to diagram top, injecting products 16 is made to depart from male die core 8 and move upward, in this process, slide block 12 is due to the guide effect of Angle Pin 13, moving upward simultaneously to the motion of diagram left side, spring 11 gradually reduces under middle shoulder thimble 10 acts on;
2, second state (Fig. 2) after die sinking, thimble panel 4 and Ejector Retainer Plate 5 are under machinery ejects effect, top board 1 is driven to continue to move with uniform velocity to diagram top together by contour screw 7, simultaneously, thimble panel 4 also drives slide block 12, continue to move with uniform velocity to diagram top, now slide block 12 is due to the guide effect of Angle Pin 13, move upward continue simultaneously to diagram left side motion, middle shoulder thimble 10 is then along with the end face 15 of slide block 12 moves to oblique portion 152 by putting down to portion 151, the change of end face 15 track, become acceleration from the uniform velocity moving upward gradually to move upward, spring 11 continues compression under middle shoulder thimble 10 acts on,
3, the third state (Fig. 3) after die sinking, thimble panel 4 and Ejector Retainer Plate 5 are under machinery ejects effect, top board 1 is driven to continue to move with uniform velocity to diagram top together by contour screw 7, simultaneously, thimble panel 4 also drives slide block 12, continue to move with uniform velocity to diagram top, now slide block 12 is due to the guide effect of Angle Pin 13, move upward continue simultaneously to diagram left side motion, middle shoulder thimble 10 continues to move upward until injecting products 16 departs from male die core 8 completely along with slide block 12 end face 15 track continues to do acceleration, spring 11 continues compression under middle shoulder thimble 10 acts on.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from the scope that spirit of the present invention defines.
