骨轮注塑模设计
摘要：针对塑料骨轮薄壁的特点，设计了一副具有侧抽芯功能的模具，并介绍了该模具的结构和工作过程以及注射模的设计方案、设计要点和模具设计时应注意的问题，并对浇注系统的设计计算作了较详细的阐述。
根据注射模的结构和设计要求，以及尺寸等各项因素。该注射模采用了一模一件的模具结构和脱件板顶出装置。根据注射模和注射机的关系选择注射机和确定塑件的注射工艺参数。注射模的结构设计包括分型面选择、确定型腔的排列方式、浇注系统设计和成型零件结构设计。
该模具结构紧凑，合理经生产使用，各部分动作准确可靠，有效地解决了点浇口注射成型模成型薄壁制品常见的缺陷问题，塑件质量稳定，符合设计要求，
可以实现大批量生产，而且生产效率高。

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。
