線圈骨架注塑成型工藝及模具設(shè)計(jì)
摘要：本設(shè)計(jì)題目為線圈骨架塑料成型工藝及模具設(shè)計(jì)，體現(xiàn)了板類塑料零件的設(shè)計(jì)要求、內(nèi)容及方向，有一定的設(shè)計(jì)意義。通過對(duì)該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者注塑模設(shè)計(jì)的基礎(chǔ)知識(shí)，為設(shè)計(jì)更復(fù)雜的注塑模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。
本設(shè)計(jì)運(yùn)用塑料成型工藝及模具設(shè)計(jì)的基礎(chǔ)知識(shí)，首先分析了塑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，便于選取注塑機(jī)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(jì)參數(shù)、設(shè)計(jì)要點(diǎn)及推出裝置的選取。
根據(jù)本塑件結(jié)構(gòu)，塑件很薄，為了使其在推出的時(shí)候不變形，必須采用推桿推出機(jī)構(gòu)。這種推出機(jī)構(gòu)非常適合在本副模具中使用。

Coil skeleton injection molding craft and mold design
Abstract:The topic of design for the designing of injection molding of coil skeleton, reflects the type of plastic parts of the shell design, content and direction of a certain design significance. Parts of the mold through the design, the designer has been further strengthened by the injection mold design based on knowledge, for the design of more complex injection molds made and lessons foreshadowing a more profound experience.
The designing of the use of injection molding and die designing of the basic knowledge, the first analysis of the plastic parts of the composition and performance requirements, select the type of gate prepared for the then estimate the volume of plastic parts, injection molding machines and facilitate the selection of identified Cavity volume of the final pieces of plastic the characteristics of the design parameters established mold, design elements and the introduction of the device selected.
According to this models a structure, models to be very thin, to cause it in promotes time does not distort, must use the throwout lever ejecting mechanism. This kind of ejecting mechanism is suitable in this mold to use.
