Tablet press moldBefore installation, the power supply of the tablet press must be cut off, and the cover plate, down punch up rail, hopper, and feeder must be removed. Open the right door, gradually clean the working surface, mold holes, and installation dies of the turntable, and apply some vegetable oil outside the middle mold and punch rod to adjust the thickness of the sheet to above 5.

Installation method of circular piece

The installation of the middle mold in the tablet press involves loosening the embossed screws screwed onto the upper track cover plate, pulling out the cover plate, and lightly tapping the middle mold with a punch rod from the punching hole to insert it into the middle mold hole. The middle mold must not protrude above the working surface of the turntable and should be checked one by one to avoid errors. When installing the middle mold, you can rotate the test wheel on the inner side of the lower part of the machine to turn the turntable clockwise, and then fix it with the middle mold screw.

The installation of the upper punch on the tablet press involves removing the cover plate on the upper rail guide plate, gradually inserting the upper punch rod into the hole, rotating the punch rod with the thumb and index finger, and checking that the head slides smoothly up and down into the middle mold without any hard friction, which is considered qualified. After installing all the punch rods, tighten the cover plate.

The installation of the tablet press down punch involves removing the down punch up rail using the same installation method as the up punch. After installation, the down punch up rail is installed and secured with screws. (Note that during the installation of the downward moving upward rail, it must be tightly attached to the outer circle of the middle plate positioning)

full setTablet press moldAfter installation, turn the handwheel to rotate the turntable twice, observe the entry of the upper and lower punch rods into the middle mold hole and the operation of the rail guide. It should be flexible, without collision or hard rubbing. It is advisable to raise the punch rod 0.05-0.15 above the working surface of the turntable when it reaches the highest point (i.e. the discharge point) to avoid damaging the punch and other parts. Then turn on the machine and run it idle for 5 minutes until it runs smoothly before putting it into production.

Installation of irregular molds for tablet presses (geometric shapes such as triangles, ellipses, and rectangles are all referred to as irregular shapes)

First, install the guiding flat key onto the upper punch rod and tighten it with screws.

The punch rod and middle mold on the tablet press must be installed synchronously. Press the directional key to insert the punch into the punch hole. Flexible up and down in East China, without any hard rubbing phenomenon. Then lift the upper punch rod and put it on the middle mold. Insert the head of the upper punch rod into the middle mold hole, align the middle mold with the mold hole, place it flat, and gently tap the tail of the upper punch rod with a striking rod to drive the middle mold in. After the middle mold enters the mold hole, its plane must not be higher than the working surface of the turntable to be qualified. Then tighten the screws of the middle mold and check that the head of the punching rod slides smoothly up and down into the middle mold without collision or hard rubbing, which is qualified.

Installation of the punch rod under the tablet press. Remove the upward rail from the lower punch and install the punch rod. Check that the head of the lower punch rod moves up and down into the middle mold flexibly, without collision or hard rubbing. After all the lower punch rods are installed, install the upper rail of the lower punch and tighten it with screws. (Note that during the installation of the downward moving upward rail, it must be tightly attached to the outer circle of the middle plate positioning)

After completing the installation of the entire middle mold, turn the handwheel to rotate the turntable 2-3 times. Observe the flexible operation of the upper and lower punch rods entering the middle mold hole and on the upper and lower guide rails, without collision or hard rubbing. Note that when the punch rod rises to the maximum power level (i.e. the discharge point), it should be 0.05-0.15 millimeters above the plane of the turntable. Then start the motor and run it idle for 5-10 minutes until it runs smoothly without any abnormalities before it can be put into normal production.
