Embodiment Construction

[0083] figure 1 and 2 Simplified diagram showing a multi-part tool in the feed position below the extrusion head 1 of the blow molding tool comprising the blow mold halves 1a, 1b and the feed device 2 comprising the arrangement Seal frames 4a, 4b on feed frame 3. The sealing frames 4a, 4b are movable relative to the feed frame 3 in the closing direction of the blow mold halves 1a, 1b and in the opposite direction thereto. The blow mold halves 1a, 1b are arranged in a known manner in a clamping frame (not shown), by which means they can be displaced towards or away from each other from an open position to a closed position and vice versa. Hereinafter, the open position is referred to as the receiving position.

[0084] At least the blow mold halves 1a, 1b or their mold platens are arranged on a common clamping frame (not shown), which can be displaced from a position below the extrusion head 1, hereinafter referred to as the feed position, to the paper The out-of-plane, her...

Abstract

The invention relates to a method for producing hollow bodies from thermoplastic material and to a device for carrying out the method. The method comprises: forming at least two sheet-like preforms (6a, 6b) of thermoplastic material in web form into two complementary shells in a multi-part tool forming a mold cavity in a closed position; and joining the housings together to form a substantially closed hollow body, the preform enters between the tool parts in the open receiving position of the tool parts, and the preform is placed into the part cavity by applying a pressure differential and at least part of it Shaped into a shell. The shells are joined together to form a substantially closed hollow body by closing the tool to form a closed mold cavity. The method is distinguished in that the preform is formed in the component cavity when the tool component is in the open receiving position.

Description

technical field [0001] The invention relates to a method for producing hollow bodies from thermoplastic material, comprising: forming in a multi-component tool at least two sheet-like preforms of thermoplastic material in web form into two complementary shells, wherein, the multi-part tool forms the mold cavity in a closed position; and joining the shells together to form a substantially closed hollow body, the preform is introduced between the parts of the tool with the tool parts in an open receiving position, and the preform passes through The applied pressure differential is placed into the component cavity and at least partially formed therein into a shell, and the shells are joined together to form a substantially closed hollow body by a closing tool to form a closed mold cavity. [0002] The invention also relates to a device for carrying out the method. Background technique [0003] A method of the type mentioned at the outset is known, for example, from DE 10 2010 ...
