The oil pad manufacturing method comprises the following steps:

correspondingly, the present disclosure also provides an oil pad manufacturing method, which is implemented based on the oil pad manufacturing mold, and includes the following steps:

s101: preparing a master tape 300, and placing the master tape 300 between an upper mold body 12 and a lower mold body 11;

specifically, the master batch belt 300 may be a metal coil or other material, and the metal coil is schematically loaded onto the oil pad manufacturing mold with reference to fig. 7 of the accompanying drawings; specifically, the movement of the master tape 300 is generally driven by an external device, and in particular, the driving device of the master tape 300 is not additionally described in the embodiment of the present disclosure with respect to the outside of the oil pad manufacturing mold.

Specifically, the master material belt 300 includes working master batch and non-working master batch, and only the master batch belt 300 located between the upper die main body 12 and the lower die main body 11 is the working master batch, wherein the working master batch located on the first station 100 is in an unproductive state, and the working master batch located on the second station 200 is in a first production state with an oil outlet. Specifically, since the oil pad of the embodiment of the present disclosure is manufactured in a continuous operation manner in steps, a structure of the master batch may be changed during the manufacturing process of the oil pad, and the embodiment of the present disclosure distinguishes different structural forms of the master batch tape 300 according to different states.

S102: the upper die body 12 moves towards the lower die body 11, the oil outlet stamping die works to stamp an oil outlet on the working master batch in an unproductive state, the working master batch on the first station 100 is converted into a primary production state, the outer contour cutting die works to cut an oil pad on the working master batch in the primary production state, and the working master batch on the second station 200 is converted into a finished production state;

in the action of the primary oil pad manufacturing die, the oil pad manufacturing die respectively and synchronously performs two punching operations on different areas of the master batch belt 300, and oil outlets are processed in corresponding areas on the master batch belt 300 on the first station 100; in the second station 200, the corresponding area on the master batch belt 300 is punched out of the outer contour of the oil pad on the basis of the oil outlet, so that the oil pad to be produced is obtained.

The produced oil pad can be taken out by a machine or a worker.

S103: the master batch belt 300 is driven to move, the working master batch in the manufacturing state is moved out of the oil pad manufacturing die, the working master batch in the primary manufacturing state is moved to the second station 200, and part of the non-working master batch is moved to the first station 100.

Through the movement of the master batch belt 300, the waste materials are moved out, the master batch belt with the oil outlets moves to the second station 200, the non-working master batch moves to the first station 100, and the next round of operation of the oil pad manufacturing die can be carried out.

For the oil blanket preparation mould structure of this disclosed embodiment, it is further characterized in that second station 200, be provided with on the lower mould main part 11 and cut lower mould subassembly, be provided with on the last mould main part 12 and cut under the condition of last mould subassembly, the operation of outline cutting die includes:

s201: driving the upper die body 12 to move towards the lower die body 11, the cutting upper die body 33 and the moving upper ring 32 moving synchronously with the upper die body 12;

specifically, the mode of realizing the synchronous motion of the upper die body 12, the cutting upper die body 33 and the moving upper ring 32 in the embodiment of the present disclosure is as follows: referring to the structure shown in fig. 8, a first elastic member 34 is disposed on the back of the cutting upper die main body 33, and the movement of the upper die main body 12 drives the movement of the cutting upper die main body 33; the moving upper ring 32 is of unitary construction with the upper mold body 12.

It should be noted that, in the schematic view, the cutting upper die main body 33 is level with the bottom surface of the moving upper ring 32, and in practical implementation, under the action of the first elastic member 34, the bottom surface of the cutting upper die main body 33 is lower than the bottom surface of the moving upper ring 32 without external force.

S202: the bottom surface of the upper cutting die main body 33 presses the working master batch in the first contour area onto the top surface of the lower cutting die main body;

specifically, the bottom surface of the upper cutting die main body 33 presses the working master batch in the first contour area onto the top surface of the lower cutting die main body, and the material on the working master batch, which is required to form the oil pad plane area, is clamped and fixed;

s203: the moving upper ring 32 retreats after continuously moving downwards to the preset position;

specifically, the action of the moving upper ring 32 is mainly to cut the semi-finished master batch with the edge having the second profile from the working master batch through the cooperation of the first cutting edge 38 and the second cutting edge 36; specifically, in this step, the cutting upper die body 33 and the cutting lower die body are kept fixed by the first elastic member 34, and the moving lower ring 30 is synchronously pressed down.

It should be noted that the downward movement of the moving upper ring 32 in this step requires a design based on the height of the crimping groove 35, because the crimping groove 35 on the inner side of the moving upper ring 32 also functions as a relief for the material during this action, and it is necessary to avoid the moving position of the moving upper ring 32 being too low to avoid the material being damaged by the inner side wall of the moving upper ring 32.

The moving upper ring 32 needs to be retracted to avoid a space for folding the folded edge.

S204: the moving lower ring 30 moves upwards to a preset position and then retreats;

specifically, the movement of the lower ring 30 mainly needs to drive the semi-finished product master batch between the first profile and the second profile to turn over upwards, and the semi-finished product master batch between the first profile and the second profile forms a turned edge.

S205: the moving upper ring 32 is moved down to a predetermined position and the hemming groove 35 processes the hemming edge as a hemming protrusion.

In particular, the action of the moving upper ring 32 in this step functions to crimp the hem into a hem projection.

Further, cut under the condition that mould assembly still includes last clamping ring 31 on the mould, the operation of outline cutting die includes: before the first cutting edge 38 and the second cutting edge 36 cooperate to cut the semi-finished master batch with the edge having the second contour from the working master batch, the upper pressing ring 31 is pressed on the working master batch with a preset pressure. Specifically, the action of the upper pressing ring 31 is independently controlled by an external device through the connecting piece 42, and the upper pressing ring 31 plays a role in pre-fixing the master batch on one hand and prevents the master batch from deforming and wrinkling on the other hand.

In summary, the present disclosure provides an oil pad, an oil pad manufacturing mold and an oil pad manufacturing method, the oil pad is convenient for waste oil to be discharged by arranging an oil outlet, the oil pad manufactured by using a thin material can be slightly deformed under the weight of food, so that the waste oil can be rapidly and automatically discharged from the oil outlet; the bulge on the periphery of the oil pad can prevent waste oil from overflowing; the oil pad manufacturing die and the oil pad manufacturing method can simultaneously execute two punching process procedures, and have high processing efficiency; on second station 200, this oil blanket preparation mould can integrate two processes of cutting oil blanket edge profile and oil blanket edge turn-up at the one-time operation in-process, has further improved the machining efficiency of oil blanket, has good practicality.
