[0029] Refer to the following Figure 1 The embodiment mold of the present invention is described as follows:

[0030] An in-mold processing mold, comprising:

[0031] The upper mold 101 has a first motor slideway inside which the power supply motor slides up and down;

[0032] The lower mold 201 has a second motor slideway inside which the power supply machine slides up and down;

[0033] A first motor 103, slidably disposed in the first motor slideway, and a motor shaft thereof is connected to the first milling cutter 102;

[0034] A second motor 203 is slidably disposed in the second motor slideway, and a second milling cutter 202 is connected to its motor shaft;

[0035] The upper die 101 and the lower die 201 can move up and down towards each other, the cutter head of the first milling cutter 102 faces the lower die, and the cutter head of the second milling cutter 202 faces the upper die.

[0036] Specifically, the upper die 101 and the lower die 201 can be directly mounted on the punch press, and the two are driven by the punch press to move toward each other; or a guide column can be added between the upper die 101 and the lower die 201 to make the two move toward each other accurately, the motor is slidably arranged on the upper die 101 and the lower die 201, the first milling cutter 102 and the second milling cutter 202 can be directly connected to the corresponding motor shaft, or can be connected to the corresponding motor shaft through a transmission component. A driving component can also be connected to drive the first motor 103 and the second motor 203 to move up and down, and the driving component can be a cylinder, a lead screw, a linear motor, etc.

[0037] In this embodiment, the following effects are also achieved: the upper surface or the lower surface of the workpiece can be processed as required, which provides production flexibility.

[0038] In some embodiments of the present invention, a push rod assembly 300 is also included. Figure 2 , the push rod group 300 includes:

[0039] The main push rod 301 has a first inclined surface 306 on its circumference for pushing the upper slider 302 and the lower slider 303 to slide;

[0040] The upper slider 302 is slidably connected to the upper mold 101, and a first sliding portion 307 in contact with the first inclined surface 306 is provided at its end, and a second inclined surface 304 is provided on its upper surface for driving the first motor 103 to move;

[0041] The lower slider 303 is slidably connected to the lower mold 201 , and a second sliding portion 308 in contact with the first inclined surface 306 is provided at its end, and a third inclined surface 305 for driving the second motor 203 to move is provided on its lower surface.

[0042] Specifically, in this embodiment, the movement direction of the upper slider 302 is perpendicular to the movement direction of the first motor 103, the movement direction of the lower slider 303 is perpendicular to the movement direction of the second motor 203, and the movement direction of the main push rod 301 is perpendicular to the movement directions of the upper slider 302 and the lower slider 303 at the same time.

[0043] Specifically, the first inclined surface 306 is in contact with the upper slider 302 and the lower slider 303 at the same time. Therefore, when the main push rod 301 is moving, it can push the upper slider 302 and the lower slider 303 to move at the same time, and then the upper slider 302 and the lower slider 303 respectively push the first motor 103 and the second motor 203 to move at the same time, so that the movements of the first motor 103 and the second motor 203 are consistent, thereby prompting the first milling cutter 102 and the second milling cutter 102 to contact the workpiece at the same time, with uniform force, high machining accuracy, and improved machining efficiency.

[0044] More specifically, the movement direction of the main push rod 301 should be parallel to the movement direction of the upper die. When this embodiment is installed on a punch press, it is convenient for the main push rod 301 to directly receive power from the machine tool.

[0045] As a control of the movement direction of the push rod assembly 300, in this embodiment, a second channel for overlapping the movement path of the upper slider 302, a third channel for overlapping the movement path of the lower slider 303, and a first channel for overlapping the movement path of the main push rod 301 can be provided. The second channel can be provided in the upper mold, and the third channel can be provided in the lower mold. The third channel can be divided into two parts, which are respectively located in the upper mold and the lower mold. The above three channels make the movement of the push rod assembly 300 more precise, thereby further improving the accuracy of this embodiment.

[0046] In some embodiments of this example, a fourth inclined surface slidably connected to the second inclined surface 304 is disposed on the lower surface of the upper mold 101 , and a fifth inclined surface slidably connected to the third inclined surface 305 is disposed on the upper surface of the lower mold 201 .

[0047] The upper die 101 and the lower die 201 are respectively slidably connected with the upper slider 302 and the lower slider 303 via the inclined surfaces, thereby improving the transmission effect and facilitating the efficient operation of the present embodiment.

[0048] In some embodiments of the present invention, the lower mold 201, the upper slider 302 and the lower slider 303 are all provided with a return spring.

[0049] The first motor 103 can reset itself under the action of gravity. The second motor 203 needs a reset spring to provide a force to press it against the lower slider 303, and the lower slider 303 and the upper slider 302 also need a reset spring to provide a force to press them against the main push rod 301.

[0050] In some embodiments of the present invention, the movement direction of the main push rod 301 is parallel to the movement direction of the upper mold 101 or the lower mold 201 .

[0051] The movement direction of the main push rod 301 is parallel to the movement directions of the upper die 101 and the lower die 201, so that the main push rod 301 can directly receive power from the punch press.

[0052] In some embodiments of the present invention, a mold core is further included, which is arranged between the upper mold 101 and the lower mold 201 for holding the workpiece, and milling cutter holes 403 are provided at the projection positions of the first milling cutter 102 and the second milling cutter 202 on the mold core.

[0053] Specifically, the mold core can be set on the punch press through a fixing component and adjusted to be located between the upper mold 101 and the lower mold 201. A milling cutter hole 403 is provided to prevent the milling cutter from damaging the mold core and preventing the milling cutter from hitting the mold core to generate vibration and affect the processing accuracy.

[0054] In some embodiments of the present invention, reference Figure 3 The mold core is composed of a plurality of arranged workpiece support blocks 401 , each of which has a workpiece groove 402 matching the shape of the workpiece, and the milling cutter hole 403 is disposed on the workpiece support block 401 .

[0055] Specifically, in some automated production scenarios, in order to facilitate workpiece feeding, a mold core is composed of multiple workpiece support blocks 401 that can carry workpieces. The arrangement of the workpiece support blocks 401 coincides with the feeding path of the workpiece, and the distance between two adjacent workpiece support blocks 401 is the same as the horizontal distance between the first milling cutter 102 and the second milling cutter 202. During processing, each workpiece support block arrives at the corresponding positions of the first milling cutter 102 and the second milling cutter 202 in turn, so that this embodiment can process two workpieces at the same time, and each workpiece is processed by the first milling cutter 102 and the second milling cutter 202 in turn, so that smooth and clean holes are obtained on both sides of the workpiece.

[0056] More specifically, the workpiece support blocks 401 may also be connected in series via an automated feeding device to make their movements more uniform, thereby improving processing accuracy.

[0057] In some embodiments of the present invention, reference Figure 4 , the milling cutter hole 403 is located in the workpiece groove 402.

[0058] The milling cutter hole 403 is arranged in the workpiece groove 402 so that when the milling cutter processes the workpiece, the workpiece can fit in the workpiece groove 402, so that the force on the workpiece is more uniform.

[0059] According to an embodiment of the present invention, the upper mold and the lower mold are combined to form a mold body, and a plurality of small chambers and a main chamber are sequentially provided in the mold body along the workpiece feeding direction.

The cutter head of the first milling cutter and the cutter head of the second milling cutter can both enter the main chamber, and the cutter head of the first milling cutter 102 and the cutter head of the second milling cutter 202 can both enter the main chamber, and the workpiece support block 401 gradually enters into the main chamber from the small chamber in sequence.

[0060] Specifically, the workpiece support block 401 carrying the workpiece is located in the small cavity when not being processed, so as to prevent interference with the upper mold 101 or the lower mold 201 and damage to the mold.
