骨輪注塑模設(shè)計(jì)
摘要：針對(duì)塑料骨輪薄壁的特點(diǎn)，設(shè)計(jì)了一副具有側(cè)抽芯功能的模具，并介紹了該模具的結(jié)構(gòu)和工作過(guò)程以及注射模的設(shè)計(jì)方案、設(shè)計(jì)要點(diǎn)和模具設(shè)計(jì)時(shí)應(yīng)注意的問題，并對(duì)澆注系統(tǒng)的設(shè)計(jì)計(jì)算作了較詳細(xì)的闡述。
根據(jù)注射模的結(jié)構(gòu)和設(shè)計(jì)要求，以及尺寸等各項(xiàng)因素。該注射模采用了一模一件的模具結(jié)構(gòu)和脫件板頂出裝置。根據(jù)注射模和注射機(jī)的關(guān)系選擇注射機(jī)和確定塑件的注射工藝參數(shù)。注射模的結(jié)構(gòu)設(shè)計(jì)包括分型面選擇、確定型腔的排列方式、澆注系統(tǒng)設(shè)計(jì)和成型零件結(jié)構(gòu)設(shè)計(jì)。
該模具結(jié)構(gòu)緊湊，合理經(jīng)生產(chǎn)使用，各部分動(dòng)作準(zhǔn)確可靠，有效地解決了點(diǎn)澆口注射成型模成型薄壁制品常見的缺陷問題，塑件質(zhì)量穩(wěn)定，符合設(shè)計(jì)要求，
可以實(shí)現(xiàn)大批量生產(chǎn)，而且生產(chǎn)效率高。

Abstract
In view of the plastic bone turn of thin wall characteristic, designed to have the side to pull out the core function the mold, and introduced the question which this mold structure and the work process as well as injected the mold the design proposal, the design main point and the mold designed when should pay attention, and to poured the system the design calculation to make the detailed elaboration.
According to injects the mold the structure and the design request, as well as size and so on each factor. This injection mold has used a mold mold structure and escapes a board to go against the installment. According to injects the mold and the injection machine relations choice injection machine and the determination models the injection craft parameter. Injects the mold the structural design including to divide the profile choice, the deterministic cavity arrangement way, pours the system design and takes shape the components structural design.
This mold structure compact, reasonably after production use, each part of movements accurate reliable, effectively solved a runner to inject the mold to take shape the thin wall product common flaw question, modelled a quality stably, conformed to the design requirement, might realize the mass production, moreover the production efficiency was high.
Key word
The bone wheel, injects the mold, the thin wall, the side pulls out the core。
