Mould closing device of vertical injection moulding machine

Abstract

The invention discloses a mould closing device of a vertical injection molding machine, comprising a seat frame and a fixing plate on the seat frame, wherein a mould is arranged on the fixing plate to ensure that the mould fixed by the fixing plate cannot swing during the injection moulding work; the periphery of the mould is provided with a plurality of guide pillars; a cross, a toggle, a guide plate and a hydraulic oil cylinder below the guide plate are arranged under the fixing plate; an upper active plate and a lower active plate which can move up and down at the guide pillars are respectively arranged above the mould and under the guide plate; the cross and the toggle as well as the upper active plate and the lower active plate are connected through a gearing system or a chain-link device so as to realize a continuous action; and the cross and the toggle are connected with the upper active plate and the lower active plate under the pushing action of the hydraulic oil cylinder so as to do a mould closing action towards the mould. The mould closing device of the vertical injection molding machine has the advantages of simple structure, ingenious ideas, low manufacturing cost, and convenience for maintenance and is very convenient and practical; and by means of the mould closing device, the shortcomings such as complex structure, high manufacturing cost, high failure rate and the like in a conventional mould closing device are overcome.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to a mold clamping device for a vertical injection molding machine. Background technique [0002] At present, there are many types of injection molding machines on the market, including vertical and horizontal structures. For vertical structure injection molding machine clamping devices, most of the structures are relatively complicated, with high manufacturing costs and high failure rates. It is inconvenient, so designing a vertical injection molding machine that improves the mold clamping device of the prior art to make it simple in structure and convenient for maintenance is a design of the present invention. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a mold clamping device for a vertical injection molding machine with simple structure, ingenious...
