Product Inquiry

قالب التشكيل الحراري هو جوهر عملية الإنتاج بأكملها.

مهمتها هي تشكيل الصفيحة البلاستيكية المسخنة والمخففة في شكل كوب محدد.

يمكن تقسيم مبدأ عملها إلى عدة مراحل رئيسية والعمل التعاوني للمكونات. تشكيل قالب

Positive - يستخدم بشكل أساسي للمنتجات المسحوبة بعمق (على سبيل المثال ، الكؤوس)
هذه هي الطريقة السائدة لإنتاج الأكواب ، لأنها تضمن سمك جدار أكثر اتساقًا ، خاصة في الأسفل والزوايا.

خطوات مبدأ العمل:

1. لقط وتسخين: يتم تثبيت الصفيحة البلاستيكية بإحكام وتثبيتها بواسطة إطار القالب (إطار التثبيت) و heheing التمدد المسبق (الخطوة الرئيسية):

القالب الإيجابي (القابس) فوق القالب - قالب محدب يشبه الجدار الداخلي للكوب - يتحرك لأسفل. بالقرب من العمق النهائي. يوزع هذا الإجراء المواد مسبقًا ، مما يمنع تمدد الورقة أو ترققها أو حتى تمزيقها أثناء النفخ اللاحق. تشكيل ضغط الهواء:

بمجرد وصول القالب الإيجابي إلى الموضع المحدد مسبقًا ، يتم إدخال الهواء المضغوط بين القالب الإيجابي والورقة. (مثل محيط الكأس وأضلاع التسليح) .

في بعض التصميمات ، يمكن أيضًا تطبيق فراغ من أسفل القالب السلبي في وقت واحد ، باستخدام الضغط الجوي لمساعدة الورقة في الالتصاق عن كثب بالقالب.

4. التبريد والتفريغ:

بمجرد أن تتوافق الورقة تمامًا مع القالب ، يتم تنشيط نظام التبريد على الفور. يحتوي الجزء الداخلي من القالب على قنوات تبريد حيث يزيل الماء البارد المتداول الحرارة بسرعة ، مما يؤدي إلى ترسيخ البلاستيك. يتم إطلاق إطار الورقة ، وتتقدم الورقة إلى المحطة التالية ، وتدخل في عملية التثقيب.
