Further, when the moving core 165 moves upward, it moves toward the center of the needle holding plate 145 in the guide groove f shown in fig. 26, and when the moving core 165 returns downward, it moves toward both sides of the needle holding plate 145 in the guide groove f shown in fig. 26.
II, the working principle is as follows:
when it is desired to cast the molded article 445, the stationary mold part is mounted on the side of the injection or die casting machine that is not movable and the movable mold part is mounted on the side of the injection or die casting machine that is movable. After the casting molding shown in fig. 4, the injection molding machine or the die casting machine drives the movable mold part to move backward, and in this action, the compression spring 455 loses pressure to bounce and pushes the movable mold plate 225 to drive the fixed mold backing plate 235 to move towards the movable mold; as shown in fig. 10, then the fixed mold base plate 245 and the fixed mold base plate 235 are opened, i.e., the first parting is completed. When opened, the sprue bar 255 secured in the stationary die plate 245 pulls the sprue condensate from the stationary die insert 215, while a robot on the injection or die-casting machine extends into the open gap between the stationary die plate 245 and the stationary die back plate 235 to clamp the sprue condensate from the sprue bar 255 out of the mold. When the mold is opened continuously, the protrusion k on the spacing hook 295 contacts with the protrusion t at the upper end of the swing hook 305, and then the protrusion k on the spacing hook 295 pushes the swing hook 305 to rotate. The injection machine or the die casting machine continues to drive the movable mold part to move backwards, at this time, the lower terminal point of the elliptical groove c in the distance hook 295 fixedly connected to the fixed mold base plate 245 is contacted with the limit nail 415 fixedly connected to the fixed mold base plate 235, and then the distance hook 295 limits the fixed mold base plate 235 and the fixed mold plate 225 to continue to move towards the movable mold. Meanwhile, the apex of the protrusion k of the spacer hook 295 is engaged with the apex of the protrusion t of the upper end of the swing hook 305, so that the spacer hook 295 forces the hook b of the lower end of the swing hook 305 to disengage from the first stopper pin 315 fastened to the side of the movable platen 205. After the swing hook 305 is disengaged from the first stopper pin 315, the movable mold part continues to move backward, and the fixed mold plate 225 and the fixed mold backing plate 235 are restrained by the distance-measuring hooks 295 and do not move in the direction of the movable mold. Then the movable template 205 and the fixed template 225 are opened, and the second typing is completed. Referring to FIG. 12, the injection or die casting machine continues to move the movable mold part backward while the undercut of the part snaps into the transverse recess d of the translating core 165 and the part 445 is pulled by the translating core 165 from the cavity of the stationary mold insert 215 to the movable mold side. When the opening distance between the fixed mold plate 225 and the movable mold plate 205 does not affect the release of the object 445, the movable mold part stops moving backward. At this time, the center lift pin 425 and the side lift pins 435 of the injection molding machine or the die casting machine extend into the holes of the movable mold base plate 405 to push the ejector pin pad plate 125 to drive the translational core 165 to move upward, and during the upward movement, the translational core 165 pushes the workpiece 445 out of the movable mold core 185, and the translational core 165 performs a sliding translational movement toward the movable mold core 185 in the guide groove f formed by the ejector pin fixing plate 145 and the ejector pin pad plate 125. When the translation core 165 performs sliding translation action, the reverse buckle of the workpiece 445 is released from the transverse groove d at the upper part of the translation core 165, and after the reverse buckle is separated from the translation core 165, the workpiece falls out of the die by self weight and shaking force of an injection machine or a die-casting machine. (note: the action principle of the sliding translational motion of the translating core 165 is that, when the translating core 165 moves upward, the vertical surface a of the upper portion of the translating core 165 is completely separated from the vertical surface x of the movable core 185, while the inclined surface z of the translating core 165 is now in contact with the vertical surface v of the wear-resistant member 175, and when the translating core 165 continues to move upward, the vertical surface v of the wear-resistant member 175 forces the translating core 165 to perform the sliding translational motion in the guide groove f formed by the ejector pin fixing plate 145 and the ejector pad plate 125).
After the pouring is completed and the die is reset, referring to fig. 16, the injection machine or the die-casting machine drives the movable mold part to move toward the fixed mold part in the opposite direction when the movable mold part is opened, and the upper end surface of the reset rod 155 is firstly contacted with the lower plane of the fixed mold plate 225. The mold closing is continued, the reset lever 155 pushes the stationary mold plate 225 and the stationary mold base plate 235 toward the stationary mold base plate 245, at this time, the protrusion t at the upper end of the swing hook 305 is separated from the protrusion k of the spacer 295, so that the tension spring 325 is retracted without tension, and pulls the swing hook 305 to reset and hook the first positioning pin 315, the mold closing is continued, the reset rod 155 pushes the fixed mold plate 225 and the fixed mold backing plate 235 to reset to the initial state of mold opening, the reset rod 155 is reset by itself under the action of the counter-thrust of the fixed mold plate 225, and pushes the thimble pad 125 to drive the translation core 165 installed in the thimble fixing plate 145 to reset, when the translation core 165 is reset, the inclined surface p of the upper portion of the translating core 165 is brought into contact with the vertical surface x of the movable core 185 in the backward movement of the ejector fixing plate 145, so that the translating core 165 is forced to perform a sliding translation movement toward the wear-resistant member 175 in the slide groove f defined by the ejector fixing plate 145 and the ejector pad 125 by the movable core 185. When the vertical surface a of the moving core 165 is retracted to be in contact with the vertical surface x of the moving core 185, at this time, the vertical surface z2 of the moving core 165 comes into contact with the vertical surface v of the wear 175, so that the moving core 165 stops the translational action, and the translating core 165 performs only the downward returning action with the ejector pin fixing plate 145 and the ejector pad plate 125. After returning to the condition shown in fig. 18, the injection machine or the die casting machine performs the next cycle of casting to the mold.
