As shown in fig. 11, in order to realize that the first oil passage 11 supplies oil to the two first oil chambers 313 and the second oil passage 12 supplies oil to the two second oil chambers 314, respectively, the extending paths of the first oil passage 11 and the second oil passage 12 are both meandering paths. In the processing of the first oil passage 11 and the second oil passage 12, the process holes may be processed on each side wall of the mounting substrate 1, and the process holes may be finally plugged.

Preferably, as shown in fig. 11, the first oil inlet end 112 of the first oil passing passage 11 is provided on the surface of the mounting substrate 1 facing the slide plate 2, and the second oil inlet end 122 of the second oil passing passage 12 is also provided on the surface of the mounting substrate 1 facing the slide plate 2. As shown in fig. 12 and 13, a first oil inlet channel 4011 extending along the axial direction of the first dowel 401 is formed in the first dowel 401, one end of the first oil inlet channel 4011, which is far away from the mounting substrate 1, is used for being communicated with an external oil supply component, and one end of the first oil inlet channel 4011, which is close to the mounting substrate 1, is opposite to the first oil inlet end 112 and is further communicated with the first oil passing channel 11. A second oil inlet channel 4021 extending along the axial direction of the second dowel bar 402 is formed in the second dowel bar 402, one end, away from the mounting substrate 1, of the second oil inlet channel 4021 is used for being communicated with an external oil supply component, and one end, close to the mounting substrate 1, of the second oil inlet channel 4021 is arranged opposite to the second oil inlet end 122 and is further communicated with the second oil passing channel 12.

At this time, as shown by the dotted arrows in fig. 11 and 13, the external oil supply unit may supply oil into the first oil chamber 313 through the first oil inlet passage 4011, the first oil passing passage 11, and the first oil hole 315 in this order, and at the same time, the oil in the second oil chamber 314 may be discharged to the external oil supply unit through the second oil hole 316, the second oil passing passage 12, and the second oil inlet passage 4021 in this order. That is, the die casting machine of this embodiment can realize the oil supply to the first oil chamber 313 and the second oil chamber 314 without additionally arranging the pipes by arranging the first oil inlet channel 4011 and the second oil inlet channel 4021 in the first dowel 401 and the second dowel 402, respectively, and arranging the first oil passage 11 and the second oil passage 12 in the mounting substrate 1, so that the external pipes of the die casting machine are fewer, the connection joints are reduced, and the problem of pipe winding in the die casting machine operation process can be avoided.

As shown in fig. 12 and 13, a wire passing channel 4031 is formed in each third dowel bar 403, and a cable penetrates the wire passing channel 4031 from one end of the third dowel bar 403 away from the mounting substrate 1, and penetrates the wire passing channel 4031 from one end close to the mounting substrate 1, and then reaches the third avoidance hole 24, and is connected with the limit switch 5 in the corresponding third avoidance hole 24. Through setting up line passageway 4031 in third dowel bar 403, make the cable (including power cord and signal line) of being connected with limit switch 5 can not expose, and then avoid the cable to use the damage for a long time, perhaps take place the winding problem with other parts.
