畢業(yè)設計題目：按鍵注塑模具的設計
摘要
根據(jù)塑件的簡單結(jié)構(gòu)的特點，本模具合適選用側(cè)澆口和單分行面，型芯適合整體加工、，使模具結(jié)構(gòu)合理，運行靈活、平穩(wěn)、可靠。
概塑件是一個簡單的按鍵 ，以它為例來介紹結(jié)構(gòu)簡單、形狀規(guī)則的該塑件的成型工藝和模具設計。采用推件板頂出機構(gòu)，使塑件一次性成型。即不需要定模抽芯機構(gòu)和楔柱連桿聯(lián)合機構(gòu)共同完成塑件抽芯，直接由推件板進行脫模，制件就從型芯脫下，可以保證制品的成型質(zhì)量。實踐運行安全可靠，自動化程度高，能滿足產(chǎn)品成型要求。

Abstract
According to the structure characteristics of plastic part with complex profile,through proper selection of adirect gate and a simple parting line and reasonable ,combination of the slant sliding core、spring、and movable insert of the core-pulling system,the mould structure was designed reasonblly and safely 。
The plastic part is a bucket lid with the inside slot of the part 。Taking the bucket lid as example , the moulding of the plastic part with complicated structure and irregular shape was introduced 。By adopting the multi-combination core-pulling mechanism,the plastic could be formed by a single moulding 。Practices proved the multi-combination core-pulling mechanism run safe and reliable , and is of hige-level antomation ,could meet the requirement of the products 。
