The invention discloses a reversible mold clamping device for an injection molding machine. mechanism. When the upper and lower molds need to be closed, the upper mold is installed under the first hydraulic column or on one side of the turning mechanism, and the clamping mechanism drives the upper mold to move. Until the upper mold moves directly above the lower mold, the position of the upper mold can be adjusted conveniently and quickly, and it can fall into the upper part of the lower mold after a long period of adjustment. The mold closing is more accurate, and it is not easy to be damaged by collision during mold closing. It avoids that the position between the upper and lower molds is not accurate enough when the mold is manually clamped, and the inside of the mold cavity is prone to collision damage.
