Problems solved by technology

[0014] 1. The structure of the head plate is complex, the processing cycle is long and difficult
[0015] 2. The clamping cylinder has a long stroke and a large oil consumption
[0016] 3. Poor mold breaking accuracy
[0017] 4. To disassemble the machine, the pull rod must be removed. Opening the cylinder head will waste hydraulic oil and damage the seals

Description

technical field [0001] The invention relates to a component of an injection molding machine, in particular to a mold clamping mechanism of an injection molding machine. Background technique [0002] At present, in the domestic injection molding machine industry, the connecting rod type clamping device occupies the main position, and its structure is as follows figure 1 As shown, the defect of its structure is that for a certain tonnage machine, the mold opening stroke is limited by the structure, and the stroke should not be too large. For some products with deep cavity holes, this kind of machine cannot meet the requirements of the product, and the structure of the connecting rod machine is also more complicated. When the tonnage of the machine is relatively large, the length and weight of the machine are relatively large, and the cost will be corresponding improved. [0003] In industrially developed countries such as Germany, the United States, and Japan, most of the la...
