Large-travel mold clamping device

Abstract

The invention discloses a large-travel mold clamping device. The large-travel mold clamping device comprises a first body; a second body is fixedly connected with one side of the first body; a pressing plate is hinged to the first body; the first body stretches out of one side of the pressing plate; the other side of the pressing plate is located above the second body; a cavity is formed in the second body; one side of the bottom of the second body is provided with an oil inlet / outlet communicated with the cavity; a piston capable of stretching out of the body is further arranged in the cavity; the stretch-out end of the piston makes contact with the other side of the pressing plate; a spring mechanism is further arranged in the first body; one end of the spring mechanism is fixed in the first body; and the other end of the spring mechanism makes contact with the pressing plate. The mold clamping device is large in mold clamping travel, the requirement on the edge thickness of a mold of a customer is lowered, the work travel is 5 times that of similar products on the market, the manufacturing difficulty is low, and the large-travel mold clamping device is suitable for large batch production.

Description

technical field [0001] The invention relates to a mold clamp, in particular to a large-stroke mold clamp. Background technique [0002] During injection molding production, it is necessary to clamp and fix the injection mold on the injection molding machine. When changing the product, it is necessary to replace the mold used for loading and unloading the injection molding product. In the existing technology, the stroke of the mold clamp in the quick mold change system of the injection molding machine and the punch press is very short. Small, the requirement for the thickness of the mold edge is high, generally within plus or minus 2mm of the design stroke; in reality, the thickness of the mold edge of many customers is not standard, the gap is very large, and gaskets have to be added to the edge of the mold, which brings Inconvenient operation and certain potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the invention is to...
