Mold clamping device and injection molding machine

An injection molding machine comprising:

• a mold clamping device configured to clamp a mold;
• and
• an injection device configured to inject an injection material,
• wherein the mold clamping device includes:
• a fixed platen fixed on a bed;
• a movable platen slidably provided on the bed;
• a mold clamping housing slidably provided on the bed;
• a plurality of tie bars coupling the fixed platen and the mold clamping housing;
• and
• a toggle mechanism provided between the mold clamping housing and the movable platen,
• wherein the toggle mechanism includes:
• two mold clamping housing side links, each rotatably connected to the mold clamping housing via respective horizontal link pins;
• two movable platen side links, each rotatably connected to the movable platen via respective horizontal link pins;
• a crosshead;
• and
• two crosslinks,
• wherein the two mold clamping housing side links and the two movable platen side links are rotatably connected via respective horizontal link pins, and the two mold clamping housing side links are each connected to the crosshead via respective two crosslinks,
• wherein when the link pins connecting the mold clamping housing and the two mold clamping housing side links, the link pins connecting the movable platen and the two movable platen side links, and the link pins respectively connecting the two mold clamping housing side links and the two movable platen side links are defined as mold clamping force receiving link pins, at least one of the multiple mold clamping force receiving link pins is defined as a main lubrication target link pin, and
• wherein the main lubrication target link pin is configured to be greased with a larger amount than each of other mold clamping force receiving link pins.
