In S208, the elevating placement unit driving mechanism 51 is driven to raise the elevating placement unit 50 (the mold placing unit U1) from the intermediate position L23, and the elevating placement unit 50 reaches the second upper position L22. When the upper limit sensor 52 is turned on, the driving of the lifting / lowering unit driving mechanism 51 is stopped. In S210, the mold base side stopper drive mechanism 66 is driven to raise the mold base side stopper 65 to the upper position (state shown in the upper part of FIG. 16).

  In S212, it is confirmed that the mold base side conveyor opening / closing switch 12e is “closed”, and if it is not “closed”, it waits until it becomes “closed”. In S214, the mold base conveyor 61 is driven to rotate upstream, that is, in the extraction target drawing and transfer direction D12, the extraction target mold M2 reaches the upstream of the mold base conveyor 61, and the upstream end sensor 62 is turned on. When it becomes, the mold base side conveyor 61 is stopped. At this time, the worker pushes the mold M2 on the mold table 310 in the extraction target mold drawing and transfer direction D12 so as to be drawn and transferred to the mold table side conveyor 61. Then, the extraction target mold M2 moves in the extraction target mold drawing and transfer direction D12 from the mold base 310 to the upstream side of the mold base conveyor 61 (second placement unit U12). In S216, it is confirmed that the lift raising / lowering switch 12c is "up", and if it is not "up", it waits until it becomes "up". In S218, the lift drive mechanism 31 is driven to raise the lift 30 from the first lower position L11, and when the lift 30 reaches the first upper position L12 and the upper limit sensor 32 is turned on, the lift drive mechanism The drive of 31 is stopped. Then, the removal target mold M2 placed on the mold base conveyor 61 (second placement portion U12) is supported by the lift 30 (removal target mold support means U41) (state shown in the lower part of FIG. 16). ).

  In S220, it is confirmed that the mold base side conveyor opening / closing switch 12e is “open”, and if it is not “open”, it waits until it becomes “open”.

At this time, the driving of the mold base side conveyor opening / closing mechanism 61b is stopped. Then, the mold base side conveyors 61 and 61 (2nd mounting part U12) retract from under the type | mold M2 of extraction object. In S224, it is confirmed that the lift elevating switch 12c is “down”, and if it is not “down”, it waits until it becomes “down”. In S226, the lift drive mechanism 31 is driven to lower the lift 30 (the extraction target support unit U41) from the first upper position L12, the lift 30 reaches the first lower position L11, and the lower limit sensor 33 is activated. When it is turned on, the drive of the lift drive mechanism 31 is stopped. Then, the removal target mold M2 supported by the lift 30 (removal target mold support means U41) descends between the mold base conveyors 61 and 61, and moves up and down from the lifting / lowering placement section 50 (mold placement section U1). Retreat downward (different from the transfer directions D11 and D12) (state shown in the upper part of FIG. 17). The first lower position L11 that is the retraction position of the extraction target mold M2 is a position in the height direction in which the extraction target mold M2 can be sent and transferred toward the mold carriage 90 as it is. Therefore, the mold M2 to be taken out on the mold base side conveyors 61 and 61 (second mounting portion U12) is retracted downward to the first lower position L11, and the molds are passed through the mold base side conveyors 61 and 61. By means of means U41 to U44 that enable sending and transferring the mold M1 to be taken out toward the table 310, the mold exchange process can be performed smoothly and efficiently.

In S228, the mold base side conveyor opening / closing mechanism 61b is driven to close the mold base conveyors 61, 61 from the open position, the mold base side conveyors 61, 61 reach the closed position, and the close detection sensor 61d is turned on. At this time, the driving of the mold base side conveyor opening / closing mechanism 61b is stopped. Then, the mold base side conveyors 61 and 61 (second placement unit U12) return to the closed position where the mold M10 can be placed. In S230, the stopper driving mechanisms 66 and 68 are driven to lower both the stoppers 65 and 68 to the lower position. In S232, the mold base side conveyor 61 and the upstream side conveyor 63 are driven to circulate in the mold base 310 side, that is, the attachment target mold delivery and transfer direction D11. Then, the attachment target mold M1 is transferred from the upstream conveyor 63 (first placement portion U11) to the mold base 310 via the mold base conveyor 61 (second placement portion U12). It is sent out in the direction D11 and transferred. At this time, the operator pushes the mold M1 fed and transferred from the mold base conveyor 61 in the mounting target mold feed and transfer direction D11 so as to be placed on the mold base 310. In S234, it is confirmed that the conveyor drive switch 12f is “stop”, and if it is not “stop”, it waits until it becomes “stop”. In S236, the mold base conveyor 61 and the upstream conveyor 63 are stopped (state shown in the lower part of FIG. 17).

At this time, the driving of the mold base side conveyor opening / closing mechanism 61b is stopped. Then, the mold base side conveyors 61 and 61 (second placement unit U12) return to the closed position where the mold M10 can be placed. In S246, it is confirmed that the model truck detection sensor 13 is on, and if it is not on, it waits until it is on. Of course, if the type cart detection sensor 13 is on, the type cart 90 is located at the type cart connection position L1. In S248, it is confirmed that the lift lower limit sensor 33 is on, and if it is not on, it waits until it is turned on. In S250, it is confirmed that the lift conveyor drive switch 12g is set to “take out”, that is, to be driven in the take-out object type delivery transfer direction D14. If it is not “take out”, it waits until “take out” is set. In S252, the lift conveyor drive mechanism 41 is driven to send out and transfer the extraction target mold M2 to the lift conveyor 40 descending to the first lower position L11 in the extraction target mold delivery transfer direction D14. At this time, the operator pushes the take-out target mold M2 sent and transferred from the lift conveyor 40 in the take-out target mold feed and transfer direction D14 so as to be placed on the mold carriage 90. In S254, it is confirmed that the lift conveyor drive switch 12g is "stopped", and if it is not "stopped", it waits until it becomes "stopped". Finally, in S256, the lift conveyor 40 is stopped (state shown in the lower part of FIG. 18).

  As described above, since a plurality of molds are placed on the lifting / lowering placement unit 50 (mold placement unit U1) so as to be capable of being fed and drawn in the lateral directions D11 and D12 with respect to the mold base 310, resin molding is performed. While the product trimming apparatus 300 is trimming the resin molded product, the die M1 to be attached can be placed on the lifting / lowering placement unit 50 (mold placement unit U1). Then, since the mold of the mold table 310 is exchanged by using the lifting / lowering mounting unit 50 (the mold mounting unit U1) in a state where the mold M1 to be mounted is mounted, the trimming mold attached to the mold table 310 is used. Can be performed smoothly and efficiently, the replacement time of the trimming mold can be shortened, and the stop time of the resin molded product trimming apparatus 300 can be shortened when the trimming mold is replaced. Can do.
