control the mould moves according to the third top and moves back maximum position, third top and moves back the moment of torsion and the interior top of third mould and moves back the time, drives the interior cutter motion of mould, wherein, first top is moved back maximum position, second top and is moved back maximum position and third top and move back the maximum position mutually differently, first top is moved back the moment of torsion, second top is moved back the moment of torsion and the third top is moved back the moment of torsion mutually differently, the top is moved back the time in the first mould, the top is moved back the time in the second mould and is moved back the time mutually differently in the third mould.

4. The method according to claim 1, wherein the parameters of the in-mold jacking mode at least comprise a maximum jacking position, a jacking torque and an in-mold jacking time, wherein the jacking torque is greater than the resistance of the inner cutter of the mold during a jacking motion, the in-mold jacking time is greater than the time consumed by the inner cutter of the mold during a jacking motion, and the maximum jacking position is greater than the position of the inner cutter of the mold.

5. The method according to claim 1, wherein the parameters of the in-mold ejection mode at least comprise an ejection maximum position, an ejection torque and an in-mold ejection time, the ejection torque is greater than the resistance of the inner cutter of the mold during the ejection movement, the in-mold ejection time is greater than the time consumed by the inner cutter of the mold during the ejection movement, and the ejection maximum position is smaller than the position of the inner cutter of the mold.

6. A method according to any of claims 1 to 5, wherein said parameters of the in-mold advancement mode further comprise an in-mold advancement delay time.

7. The method according to any of claims 1 to 5, wherein the parameters of the in-mold back-up mode further comprise an in-mold back-up delay time.

8. A control device for a mold, comprising:

the first control unit is used for controlling an inner top plate of the mold to move towards a direction close to a product by adopting an in-mold jacking mode under the condition of receiving a first command, so that an inner cutter of the mold cuts off gate materials of the product, wherein the first command is generated under the condition that the gate materials exist at the tail end of the product;

and the second control unit is used for controlling the inner top plate of the mold to move towards the direction far away from the product by adopting an in-mold ejection mode under the condition of receiving a second command, so that the inner cutter of the mold cuts off the gate material of the product, and the second command is generated under the condition that the gate material exists at the beginning of the product.

9. A computer-readable storage medium characterized by comprising a stored program, wherein the program executes the control method of the mold according to any one of claims 1 to 7.

10. A control system for a mold, comprising: one or more processors, memory, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs comprising control instructions for performing the method of controlling the mold of any of claims 1-7.
