The embodiments of the present invention will be further explained with reference to the drawings.

Referring to fig. 1 to 3, the utility model discloses a two-way slider mechanism of loosing core, including preceding template 100, set up in back template 200 under the preceding template 100 with set up in backup pad 300 under the back template 200, be provided with slider assembly in the back template 200, slider assembly include first slider 210 and set up in second slider 220 in the first slider 210, be provided with in the backup pad 300 and run through the fore-set 310 of back template 200, the fore-set 310 with the bottom of second slider 220 offsets, still be provided with slider seat 230 in the back template 200, be provided with oblique guide hole 231 in the slider seat 230, be fixed with in the preceding template 100 with oblique guide pillar 110 that oblique guide hole 231 matches, slider seat 230 is connected with first slider 210. When the mold is closed, the top pillar 310 jacks up the second slider 220, so that a space 240 capable of retreating is reserved between the second slider 220 and the rear mold plate 200; when the mold is opened, the rear mold plate 200 and the support plate 300 are opened, the top pillar 310 moves downwards along with the support plate 300, the second slider 220 moves downwards to enter the reserved space 240, and the second slider is taken out of the reverse buckle in the vertical direction; after the second slider 220 is released from the undercut, the front mold plate 100 and the rear mold plate 200 are opened, the inclined guide post 110 fixed in the front mold plate 100 moves vertically upward in the inclined guide hole 231, so that the slider seat 230 provided with the inclined guide hole 231 moves horizontally outward, and at the same time, the first slider 210 connected to the slider seat 230 drives the second slider 220 to move horizontally outward, so as to release the undercut in the horizontal direction, and the demolding of the slider assembly is completed while the front mold plate 100 and the rear mold plate 200 are opened. The design is reasonable, the structure is simple and compact, the problem that the bidirectional reverse buckle cannot be demoulded is solved, and the automation of injection production is realized; the production yield is guaranteed, the production efficiency is improved, the production line is suitable for batch production requirements, and the production line is stable in operation, safe, reliable, convenient to use and high in practicability.

Further, the first slider 210 and the slider seat 230 are connected by the first bolt 250, so that the fixing is stable, the reliability is high, and the first slider and the slider seat can be connected by a buckle or glue.

As a further improvement of the above technical solution, the first slider 210 is provided with a positioning pin 260, the second slider 220 is provided with a positioning hole 270 matching with the positioning pin 260, and the above components have guiding and positioning functions, when the second slider 220 moves up and down, due to the guiding and positioning functions of the positioning pin 260 and the positioning hole 270, the second slider 220 does not deviate relative to the first slider 210, and the jamming and unsmooth movement of the second slider 220 caused by slight deviation in the horizontal direction are avoided.

Further, the second bolt 280 for fixing the second slider 220 to the first slider 210 is disposed on the second slider 220, and since the elastic element is disposed between the first slider 210 and the second slider 220, the assembly between the first slider 210 and the second slider 220 is difficult to complete due to the elastic force of the elastic element during the assembly, and the second bolt 280 can overcome the elastic force between the sliders, so that the assembly between the first slider 210 and the second slider 220 is simple and the fixation is firm.

Further, an elastic element is disposed between the first slider 210 and the second slider 220. Preferably, the resilient element comprises a spring. When the mold is closed, the elastic element is in a compressed state under the action of the top pillar 310; when the supporting plate 300 and the rear mold plate 200 are opened, the second slider 220 can be quickly taken out of the reverse buckle under the action of the elastic element, and the efficiency of opening the mold is improved.

Further, the top of the first sliding block 210 is provided with a through hole 211, so that the second sliding block 220 can be demoulded through the through hole 211 without affecting the demould of the first sliding block 210. Preferably, the second slider 220 is provided with a protruding portion 221 matched with the through hole 211, the end of the protruding portion 221 is provided with a forming portion 222 matched with the product in an inverted manner, the protruding portion 221 can move up and down in the through hole 211 to complete mold closing and mold releasing, and the forming portion 222 can complete product inverted forming.
