The utility model main purpose is to provide a kind of collapsible form structure of improved Jet forming machine, it can improve and the two frictional resistance of clamping huge pillar significantly, and the clamping huge pillar that can be fit to the different-diameter specification wears, and has industrial utilization very widely.

To achieve these goals, the utility model provides a kind of collapsible form structure of improved Jet forming machine, it is to be arranged on the clamping die device of board, and the front end of this clamping die device is provided with a fixed form that is installed in board top, parallel the extending back in the quadripolar corners place of this fixed form is installed with four clamping huge pillars, the movable outstanding collapsible form of adorning on the cylinder of this clamping huge pillar, the rear end of this collapsible form is subjected to a control that driving mechanism drives, be subjected to the driving of driving mechanism to produce the displacement of advancing, constitute a space that presss from both sides the locked mode tool with the fixed form that is positioned at its collapsible form front end; It is characterized in that:

Two side angle places, this collapsible form top are to be big aperture than its clamping huge pillar relatively for the embedded embedding hole of stretching of clamping huge pillar, make its two chimericly be formed with tangible gap; Therefore, when collapsible form when carrying out the displacement of folder locked mode tool, its can be significantly should be kind and the two frictional resistance of clamping huge pillar, and can be fit to the clamping huge pillar setting of different-diameter specification, promote its molar size, and can reduce its interelement abrasion spoilage.

Below in conjunction with drawings and Examples the utility model is described, can makes the purpose of this utility model, effect, the technological means that is adopted and structure more cheer and bright.
