Description

Just, maintain high-efficient mode locking structure of injection machine Technical Field The invention relates to an injection machine, in particular to an injection machine convenient maintenance high-efficiency mode locking structure of the injection machine. Background The main cylinder of some injection machines (200910261471.7, special injection molding machine for composite insulator) on the market is fixed on the upper end of the guide post, and the linear moving cushion block is arranged on the movable mould plate. The structure has the defects that the main oil cylinder is positioned at the highest point of the equipment, the assembly and the subsequent maintenance are inconvenient, the linear moving-out cushion block needs to be moved, but the linear moving-out cushion block has large weight and needs to be pushed by a large oil cylinder, and the large oil cylinder has relatively low speed, so that the production efficiency is reduced. Therefore, the inventor designs an injection machine of the injection machine to maintain the high-efficiency mode locking structure to solve the problems. Disclosure of Invention In order to overcome the defects in the prior art, the invention provides an injection machine of an injection machine, which is convenient to maintain an efficient mode locking structure. The technical scheme adopted for solving the technical problems is as follows: The injection machine convenient-to-maintain efficient mold locking structure comprises a guide post, a main oil cylinder, a cushion block assembly and a movable mold plate moving along the guide post, and is characterized by further comprising an upper mold plate, a base plate and a driving unit driving the base plate to move, wherein the main oil cylinder is fixedly arranged on the movable mold plate, the cushion block assembly is arranged on the main oil cylinder and connected with the main oil cylinder, the upper mold plate is fixed on the guide post and positioned above the movable mold plate, the driving unit is arranged on the upper mold plate, the upper mold plate is provided with an upper mold hole for the cushion block assembly to pass through, and the base plate can be pushed by the driving unit to close the upper mold hole so that the main oil cylinder can push the cushion block assembly to prop against the base plate.
