摘要： A thermoforming apparatus having a mould 108 with an internal vacuum chamber 111 and a quench 110 for cooling a thermoplastic sheet 104 while it remains on the mould. Because the quench cools the sheet, conventional cooling lines are eliminated from the mould. A preferred process of using the thermoforming apparatus includes drawing a heated sheet 104 over the mould 108, creating a partial vacuum in the vacuum chamber 111 of the mould to maintain the sheet on the mould and quenching the sheet on the mould in a quenching tank 113. A preferred process of manufacturing a mould with an interior vacuum chamber includes forming an impression of the mould in a casting media, suspending a vacuum line or vacuum cabinet within the impression and pouring molten material around the vacuum line or vacuum cabinet to form the mould at least partially surrounding the vacuum line or vacuum cabinet. Vacuum holes are drilled through the mould from the mould face to the vacuum chamber.

摘要翻译： 一种具有模具108的热成型设备，其具有内部真空室111和用于在保持在模具上时冷却热塑性片材104的骤冷器110。 因为淬火使片材冷却，所以常规的冷却管线从模具中消除。 使用热成型设备的优选方法包括将加热的片材104拉过模具108，在模具的真空室111中产生部分真空，以将片材保持在模具上并且在淬火槽113中将片材淬火在模具上 制造具有内部真空室的模具的优选方法包括在铸塑介质中形成模具的印模，将真空管线或真空柜悬挂在压印内，并将熔融材料围绕真空管线或真空室浇注以形成模具 至少部分地围绕真空管线或真空柜。 真空孔通过模具从模具表面到真空室钻出。
