[0015] The left side of the graphite box 1 is connected and fixed to the right end of the bracket 5, the left end of the bracket 5 is connected to the screw slider mechanism 6 and moves up and down through the screw slider mechanism 6, the screw slider mechanism 6 is vertically installed on the slide seat 7, the slide seat 7 slides with the base 10 in the horizontal direction through the slide rail Ⅰ8, the left side of the slide seat 7 is connected to the cylinder 9, the screw slider mechanism 6 includes a slider 61 fixedly connected to the bracket 5, the middle part of the slider 61 is threadedly connected to the screw 62, the upper and lower ends of the screw 62 are rotatably connected to the slide rail seat 64 through the bearing assembly, the upper end of the screw 62 is connected to the motor 65, the motor 65 is installed on the upper part of the slide rail seat 64, and the slide rail seat 64 is also provided with a slide rail 63 that slides with the slider 61.

[0016] The device is provided with a liquid inlet and a liquid return port in the inner cavity of the graphite box, which are respectively connected to the liquid inlet pipe and the liquid return pipe, and a guide channel is provided at the lower part of the graphite box to connect the liquid inlet pipe I, and an ink outlet connected to the guide channel is provided at the bottom of the graphite box and a spray head is installed. The graphite box supplies graphite to the punch and can spray graphite to the lower die at the same time.

[0017] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0018] This device is used before the workpiece is placed in the molding cavity of the lower die. The cylinder first pushes the slide seat to move right along the slide rail I as a whole, and the screw slider mechanism and the graphite box move right synchronously until the graphite box moves to between the punch and the lower die. Then the motor works, the motor intermittently rotates forward and reverse, and the rotational motion of the screw is converted into the linear motion of the slider in the up and down directions. The slider drives the graphite box to rise and fall intermittently through the bracket, and the punch reciprocates several times into the inner cavity to dip in graphite. When the punch is extended into the inner cavity, the liquid level of the graphite is above the return liquid port position, and the excess graphite will flow back to the oil supply tank along the return liquid pipe. The return liquid pipe is in a normally open state. At the same time, the spray head at the bottom of the graphite box continues to spray graphite into the molding cavity of the lower die. After completion, the cylinder drives the slide seat to move left as a whole and reset.

[0019] A liquid level sensor is provided in the inner cavity of the graphite cartridge. When the graphite liquid level in the inner cavity is lower than the set value, the valve on the liquid inlet pipe opens and a certain amount of graphite is injected into the inner cavity through the liquid inlet. The highest level of the graphite is at the return liquid port, and the excess graphite will flow back to the ink supply box along the return liquid pipe.

[0020] The graphite in the above embodiment may also be replaced by other types of lubricants.

[0021] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
