The belt carrier 30 has a pressing surface 301 and a contact surface 302 facing away from the pressing surface 301.

After the upper die 11 and the lower die 12 are opened, one end of the belt moving member 30, which is close to the molding member 20, corresponds to the port of the plugging channel 201, the extending direction of the pressing moving surface 301 crosses the direction of the molding member 20 moving and penetrating the sliding channel 102 to form an acute angle, the inclination of the pushing surface 302 is consistent with that of the pressing moving surface 301, and the inclination direction of the first inclined surface 202 is the same as that of the pressing moving surface 301.

When the belt moving member 30 is driven to be inserted into the inserting channel 201, the pressing surface 301 corresponds to the first inclined surface 202, the pushing surface 302 corresponds to the second inclined surface 203, and the belt moving member 30 presses the first inclined surface 202 through the pressing surface 301 to push the forming member 20 to move along the sliding channel 102 toward the movable space 103. In this way, the molded article 20 can be moved to a predetermined position by closing the upper die 11 and the lower die 12, and the entire molded article can be flexibly engaged without additional power.

During the process that the belt moving member 30 is driven to withdraw the inserting passage 201 and press the second inclined surface 203 of the molding member 20 through the pushing surface 302, the molding member 20 is pushed to move along the sliding passage 102 in a direction away from the movable space 103.

Preferably, the molding member 20 is movably mounted to the lower die 12, and the belt moving member 30 is mounted to the upper die 11 to reduce the load of the upper die 11 so that the die casting operation is stably performed.

It should be noted that, the belt shifter 30 and the molding member 20 are both detachable, the pressing surface 301 of the belt shifter 30 can be designed to have different inclinations, and the insertion passage 201 of the molding member 20 can be designed to have a size matching the belt shifter 30. In this way, by replacing the belt moving parts 30 with different inclinations of the press moving surface 301 and installing the different forming parts 20 in a matching manner, the belt moving parts 30 can drive the forming parts 20 to penetrate the sliding channel 102 in different degrees, so that the die casting space 1001 with different sizes is formed with the upper die 11, the lower die 12 and the plastic hole assembly 41, and the processing requirements of the workpieces with different sizes are met.

Preferably, the mounting channel 1002 extends from one end of the molding member 20 to the first inclined surface 202 and communicates with the plugging channel 201, and finally extends from the second inclined surface 203 to the other opposite end of the molding member 20.

Referring to fig. 8, preferably, when the upper die 11 and the lower die 12 are opened, a through passage 303 is formed at an end of the belt moving member 30 near the molding member 20, and the through passage 303 extends from an end of the pressing surface 301 to an end of the pushing surface 302. The size of the through passage 303 is larger than the size of the plastic hole assembly 41. When the upper die 11 and the lower die 12 are clamped and the belt shifter 30 is inserted into the insertion channel 201, the through channel 303 corresponds to the mounting channel 1002, and the plastic hole assembly 41 can move along the mounting channel 1002 and penetrate through the through channel 303, so that the requirement of the design position of the belt shifter 30 is reduced while the movement between the plastic hole assembly 41 and the belt shifter 30 is ensured not to interfere with each other.

Referring to fig. 4 to 7, the plastic hole member 40 further includes a driving member 42, the plastic hole assembly 41 is mounted on the driving member 42, and the driving member 42 is configured to drive the plastic hole assembly 41 to move along the mounting channel 1002 toward or away from the movable space 103. The forming part 20 is connected with the driving part 42, and the forming part 20 can drive the plastic hole member 40 to move together while moving in the sliding channel 102.

When the upper die 11 and the lower die 12 are clamped, and the molding member 20 is driven by the belt moving member 30 to partially extend into the movable space 103, the plastic hole member 40 is driven to be integrally close to the movable space 103, so that the plastic hole assembly 41 can be driven by the molding member 20 and the driving member 42 to move towards the movable space 103, and compared with the case that the plastic hole assembly 41 is driven by the driving member 42 only to move, the movement stroke of the plastic hole assembly 41 is greatly improved, the extension degree of the plastic hole assembly 41 into the movable space 103 is increased, and the depth of the hole of the workpiece after die casting is improved.

In addition, based on the fact that the plastic hole component 40 is driven by the forming piece 20 to approach the movable space 103, the plastic hole component 41 is driven by the driving piece 42 to move in different degrees, so that the holes of the workpiece after being die-cast are different in depth, the design range of the holes is improved, and therefore the workpieces of different types are manufactured.

Preferably, the plastic hole assembly 41 includes a plastic hole member 411 and a connecting member 412, the plastic hole member 411 is connected with the driving member 42 through the connecting member 412, and the driving member 42 can drive the connecting member 412 to move, so as to drive the plastic hole member 411 to move together.

It should be noted that the plastic hole 411 is detachably connected to the connecting piece 412, so that when the driving piece 42 and the connecting piece 412 are combined to be implemented as a cylinder or an oil cylinder, the plastic hole 411 is driven to move to different degrees by replacing the cylinder or the oil cylinder with a different model, thereby further changing the plastic hole depth to meet the processing of the workpieces with more models.

The working method of the die casting die comprises the following steps:

when the upper die 11 and the lower die 12 are clamped, the belt moving part 30 pushes the forming part 20 to move along the sliding channel 102 to be close to the movable space 103, so that part of the forming part 20 stretches into the movable space 103, and meanwhile, the forming part 20 drives the plastic hole component 40 to move close to the movable space 103;

the driving member 42 drives the molding hole assembly 41 to move along the mounting channel 1002 to approach the movable space 103, so that a part of the molding hole assembly 41 extends into the movable space 103, and the upper die 11, the lower die 12, a part of the molding member 20 and a part of the molding hole assembly 41 form a die-casting space 1001;

when the upper die 11 and the lower die 12 are released, the belt moving member 30 pushes the molded article 20 to move away from the movable space 103 along the sliding channel 102, so that the molded article 20 is pulled out of the movable space 103, and the molded article 20 drives the hole molding member 40 to move away from the movable space 103;

the driving member 42 drives the plastic hole assembly 41 to move away from the movable space 103 along the mounting passage 1002 so that the plastic hole assembly 41 is drawn out of the movable space 103 to take out the die-cast completed workpiece.
