Ultra-large plastic forming equipment

Abstract

The invention provides ultra-large plastic forming equipment. The ultra-large plastic forming equipment comprises a fixed framework, a hydraulic electrical system, a mould, an extruding-injecting mechanism and a mould closing mechanism, wherein the hydraulic electrical system is mounted on the fixed framework; the mould comprises an upper mould and a lower mould which are oppositely arranged up and down; a mould cavity is arranged inside the mould; the extruding-injecting mechanism comprises a spray nozzle section which is connected to the mould and is used for injecting molten plastic into the mould cavity of the mould; the mould closing mechanism comprises a slide block which can be movably mounted on the fixed framework up and down, and a main oil cylinder which is mounted in the slideblock; the slide block is provided with a mould connecting part; the upper mould or the lower mould is fixed to the mould connecting part; the main oil cylinder is connected to the hydraulic electrical system; and the two ends, in the vertical direction, of the main oil cylinder are separately fixed with the fixed framework and the mould connecting part in the slide block. During mould closing, the slide block drives the upper mould to move downwards or drives the lower mould to move upwards, and the hydraulic electrical system controls the main oil cylinder to add oil and increase pressure, so that mould locking force is greatly improved, and therefore, the ultra-large plastic forming equipment is suitable for producing ultra-large plastic products, and is low in cost.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to a super-large plastic molding equipment. Background technique [0002] With the development of society, super-large (over 2 meters), ultra-thick wall thickness (over 50mm), overweight (300000cm) 3 ) super-large plastic products gradually appear in industrial production. In the prior art, the main parameters of general-purpose injection molding machines are generally clamping force 55,000KN, injection volume 225,000cm 3 Below, therefore, general-purpose injection molding machines are not suitable for injection molding of super-large plastic products, so large-scale injection molding machines are required. However, it is relatively difficult to manufacture general-purpose large-scale injection molding machines, and the market price exceeds 15 million yuan, which is very expensive and unaffordable for ordinary users, and only a few domestic manufacturers can manufacture them, resu...

Problems solved by technology

In the prior art, the main parameters of general-purpose injection molding machines are generally clamping force 55,000KN, injection volume 225,000cm 3 Below, therefore, general-purpose injection molding machines are not suitable for injection molding of super-large plastic products, so large-scale injection molding machines are required

However, it is relatively difficult to manufacture general-purpose large-scale injection molding machines, and the market price exceeds 15 million yuan, which is very expensive and unaffordable for ordinary users, and only a few domestic manufacturers can manufacture them, so no manufacturers can independently produce super-large plastic products.
