[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1-2 As shown, a two-platen injection molding machine mold breaking transition oil circuit block, the injection molding machine has a first side and a second side, the first side and the second side are both provided with an upper mold locking cylinder and a lower mold locking cylinder, the two upper mold locking cylinders cooperate with the two lower mold locking cylinders to perform the mold locking action, and the injection molding machine is provided with a clamping valve plate for oil supply. In this embodiment, the two oil circuit blocks on the first side and the second side are integrated into one oil circuit block, that is, the two mold breaking transition oil circuit blocks are respectively arranged on the first side and the second side. After the two oil circuit blocks on the same side are integrated into one oil circuit block, the overall occupied volume is smaller, the cost is lower, and it is easy to manage and transport.

[0021] Among them, the mold breaking transition oil circuit block includes an oil circuit block body 1, which is fixed to the upper mold locking cylinder or the lower mold locking cylinder. In this embodiment, the oil circuit block body 1 is fixed to the lower mold locking cylinder. Therefore, when the upper mold locking cylinder is damaged and needs to be replaced, there is no need to disassemble the oil circuit block body 1, which is convenient for maintenance. At the same time, a first oil port joint 11, a first pressure relief joint 12, a second oil port joint 13 and a second pressure relief joint 14 are provided on the oil circuit block body 1. The first oil port joint 11 and the first pressure relief joint 12 can be connected to the mold clamping valve plate, and the second oil port joint 13 and the second pressure relief joint 14 can be connected to the upper mold locking cylinder or the lower mold locking cylinder. Since the oil circuit block body 1 is fixed on the lower mold locking cylinder, the second oil port joint 13 and the second pressure relief joint 14 are used to communicate with the upper mold locking cylinder, wherein the first oil port joint 11 is used to supply oil to the mold clamping valve plate, the first pressure relief joint 12 is used for exhaust and pressure relief, the second oil port joint 13 is used to supply oil to the upper mold locking cylinder, and the second pressure relief joint 14 is used to exhaust or relieve pressure on the upper mold locking cylinder. It can be seen that after integration, the oil circuit block body 1 only needs to be connected with the mold clamping valve plate and the upper mold locking cylinder, which can save the connection seal between adjacent oil circuit block bodies 1 on the same side, can greatly improve the assembly efficiency, and reduce the risk of oil leakage.

[0022] In order to facilitate the arrangement of the connecting hoses, the first oil port connector 11 and the second oil port connector 13 are respectively located on two symmetrical sides of the oil circuit block body 1, the first pressure relief connector 12 is located on one side of the first oil port connector 11, and the second pressure relief connector 14 is located on one side of the second oil port connector 13.

[0023] In order to fix the oil circuit block body 1 to the lower clamping cylinder, a plurality of first mounting holes are provided on the lower clamping cylinder, and a plurality of second mounting holes 15 are provided on the oil circuit block body 1. The plurality of second mounting holes 15 correspond to the plurality of first mounting holes one by one, and the assembly can be achieved by inserting bolts or screws into the connecting holes between the second mounting holes 15 and the first mounting holes.

[0024] In this embodiment, two shuttle valve plug-ins 2, two cartridge valves 3, two reversing valves 4 and a pressure measuring joint 5 are also included, that is, the components on the two oil circuit blocks are concentrated on an oil circuit block body 1.
