Abstract

PURPOSE:To make changing of core carriers possible without stopping a molding device by providing a traveling frame between a mold pass line and a core preparing station and an inverting frame between the latter and a core carrier preparing station. CONSTITUTION:Clamping cylinders 29 are extended and operated to grip a core carrier A20 with gripping plates 30 from top and bottom directions and to disengage the carrier A20 from a press contact plate 10; thereafter the plate 10 is retreated by a press contact cylinder 9. An inverting frame 27 is inverted 180 deg. to move a carrier B20 and to bring the rear surface of the carrier B20 in tight contact with the plate 10. Said carrier is surely gripped by the engagement with pawl members. In succession, the carrier B20 is disengaged from the plates 30, whereby the changing of the carrier A20 with the B20 is completed. Thereafter, the new carrier B20 is used, and a traveling cylinder 22 is extended and operated to move the carriage B20 together with a traveling frame 8, and the plate 10 to the position facing the mold 3, where the core held in the carrier B20 is shifted to the mold 3 side.

In this way, the cores are normally set in the mold (3) one after another.Next, we will explain the exchange operation of the core carriers A and B (20).The core carrier A (20) is placed in the core preparation station. (B) In the state shown in FIG. 1, in which the new core carrier B (20) is held by the reversing frame (27) on the side of the core carrier preparation station θ, the crimp cylinder (9 ) is pushed out to move the core carrier A (20) forward and positioned between the pair of opposing grip plates (30), and the clamp cylinder (29) is pushed out to move the core carrier A (20) forward.
(20) is gripped from above and below with the grip plate (30),
Next, after pushing out the clamp cylinder (16) to release the engagement between the claw members (19) and (21), the crimp cylinder (9) is reversely operated to retract the crimp plate (10) and as shown in the figure. Activate the reversing cylinder that is not rotated to invert the reversing frame (27) 180 degrees to remove the core carrier B.
(20) is rotated to a position opposite the pressure bonding plate (10), and then the pressure bonding cylinder (9) is pushed out again to bring the pressure bonding plate (10) into close contact with the back surface of the core carrier B (20). Next, the clamp cylinder (16) is retracted, and the taper surfaces (1) of the claw members (19) and (21) are retracted.
9a) (21a) Engage the core carrier B
After firmly gripping (20) on the front surface of the crimp plate (10), the clamp cylinder (29) is retracted to release the engagement between the gripping plate (30) and the core carrier B (20). At the same time, the crimping cylinder (9) is operated in reverse to move the core carrier B (20) back to the outside of the gripping plate (30), thereby separating the core carrier A (20) and the new core carrier B.
Complete the exchange in (20). Then, using this new core carrier B (20) t-, the core setting operation into the mold is started again. Also, during this core setting operation, the core carrier A (20) at the core carrier preparation station run (c) retracts the clamp cylinder (29) and engages with the grip plate (30). Release the core carrier and manually remove it and replace it with another core carrier to prepare for the next core carrier replacement operation.
