At this time, there is a height difference between the movable mold inner mold core 221 and the movable mold outer mold core 222, the locking assembly 315 is in a disengaged state, the third mold opening ejector pin 323 protrudes from the movable mold front template 211 and abuts against the palm-shaped mold, the mold closing return pin 330 protrudes from the movable mold front template 211, and the top of the mold closing return pin 330 exceeds the third mold opening ejector pin 321. 3; during the mold closing process, the movable mold 200 can move toward one side of the fixed mold 100 driven by the die-casting dynamic mold plate, so that the upper end of the mold closing return pin 330 abuts against the fixed mold 100, and then the fixed mold 100 can apply a reverse thrust to the movable mold front template 211 through the mold closing return pin 330, so as to drive the movable mold front template 211 to move toward the movable mold rear template 212, so that the movable mold 200 moves to the mold closing state. At this time, the movable mold outer mold core 222 is arranged around the outer periphery of the movable mold inner mold core 221 and the inner mold surfaces of the two are flush, and the locking assembly 315 is in a locked state.

[0055] In this embodiment, the driving module 300 is set in a specific form, which has the advantage of a more reasonable structural layout, so that the die-casting mold 10 has the characteristics of compact structure, easy control and high movement stability.

[0056] It should be noted that the third mold opening ejector pin 323 protrudes from the movable mold front template 211 and abuts against the palm-shaped model in any form. For example, it can abut against the palm-shaped model directly or indirectly (i.e., abut against the slag bag integrally formed with the palm-shaped model). The embodiments of the present application take indirect abutment with the palm-shaped model as an example.

[0057] See also Figure 4 and Figure 7 In order to better understand the technical solution, the relative position relationship between the slag bag groove 2221 (forming the majority of the slag bag during the die-casting process) and the runner 2222 (forming a small part of the slag bag during the die-casting process) is exemplified here in combination with the exhaust valve 2113 in the die-casting mold 10 (a structure commonly possessed by the die-casting mold 10 and used for exhausting during the die-casting process).

[0058] See also Figure 4 and Figure 7 As an example, the outer mold core 222 of the movable mold is provided with a slag groove 2221 and a flow channel 2222 corresponding to the palm-shaped model on the side close to the fixed mold 100, and the slag groove 2221 and the flow channel 2222 are connected and connected to the exhaust groove on the exhaust valve 2113, wherein the exhaust valve 2113 is embedded in the side of the movable mold front template 211 close to the fixed mold 100.

[0059] It should be noted that the exhaust groove on the exhaust valve 2113 is used for exhausting during the die-casting process and can also effectively prevent the slurry from leaking. Therefore, the exhaust groove may also form a part of slag bag during the die-casting process. Therefore, in order to more easily remove the palm-shaped model during the mold opening process, a third mold opening ejector 323 can be further provided, that is, a third mold opening ejector 323 is also provided in the corresponding area of ​​the exhaust valve 2113 (for details, please refer to Figure 7 ), so that after the mold is opened, the third mold opening ejector pin 323 can also protrude from the exhaust valve 2113 and abut against the slag bag therein, thereby assisting in disassembling the palm-shaped model. It should be noted that the relative position relationship between the locking assembly 315 and the top plate is not limited, as long as the locking assembly 315 can achieve the corresponding function, for example, the top plates are all rectangular parallelepiped, and the locking assemblies 315 are provided at both ends of the length direction of the top plates.
