膜片夾片注塑模設(shè)計
摘 要
本設(shè)計題目為膜片夾片注塑模設(shè)計,體現(xiàn)了薄壁類塑料零件的要求、內(nèi)容及方向。由一定的設(shè)計意義。通過對該零件模具的設(shè)計,進一步加強了設(shè)計者注塑模設(shè)計的基礎(chǔ)知識,為設(shè)計更復(fù)雜的注塑模做好了鋪墊和吸取了更深刻的經(jīng)驗。
本設(shè)計運用了塑料成型工藝與模具設(shè)計的知識,首先分析了塑料件的成分及性能要求,為選取澆口的類型做好了準(zhǔn)備;然后估算了塑件的體積和質(zhì)量,便于選取注塑機及確定型腔數(shù)量;最后分析了塑件的特征,確定模具的設(shè)計參數(shù)、設(shè)計要點及推出裝置的選取。
本設(shè)計運用了推板頂出機構(gòu),適合薄壁零件的推出,同時也采用了側(cè)型芯抽出機構(gòu)來設(shè)計帶有側(cè)凹或者由內(nèi)陷的塑料零件,能在不增加模具厚度的情況下,制造出較為復(fù)雜的制件。這樣的設(shè)計方式和意圖很容易理解,所以被廣泛運用。

Diaphragm Design of Injection Mold Clips
Abstract
The topic for patch injection mold Clip design, reflects the type of thin-walled plastic parts of the requirements, content and direction. Design by a certain significance. Through the design of the die parts to further enhance the design of injection mold designers the basic knowledge for the design of more complex injection mold and do a good job of paving the way to draw a more profound experience
The design of the use of plastic molding process and mold design knowledge, the first is to analy the plastic parts of the composition and performance requirements. In order to select the type of gate ready; the plastic parts and then estimate the size and quality, It’s easy to select the injection molding machine and to determine the number of cavity; the final is to analy the characteristics of plastic parts, molds to determine the design parameters, design features and the introduction of the selected device.
Using the design onto the top plate of institutions for the introduction of thin-walled parts, as well as the use of a side core design with out of body or concave side of the plastic parts from invagination can die without increasing the thickness of the circumstances, produce more complex parts. This design approach and intentions it is easy to understand, so widely used
Key words: Injection mold Gate side Side core
