Abstract

The present invention relates to a high speed direct mold clamping apparatus. The direct mold clamping apparatus has a grooved channel for the flow of oil inside a clamping cylinder to minimize the flow of oil between inside and outside the clamping cylinder. Then, the clamping ram can perform high speed reciprocation in the clamping cylinder.
