The air chamber body mold
摘 要
空气室下体的主要框架是回转体,尺寸适中,结构较为复杂。为了大批量生产此产品,在注塑此产品的过程中,零件决定需要用侧向抽芯机构,动模开模过程中斜导柱带动滑块滑动从而实现侧向抽芯和开模强制脱模动作。推杆在开模完成后在顶杆作用下推出零件。经过考虑该零件适用于一模两腔,因此在浇注系统上设计了测浇口,和分流道等。应零件尺寸较高,为避免开模行程无法满足取件要求从而采用热流道的方式浇注。排气系统由于推杆与模板及分型面与模板之间都拥有空隙的原因可以不做考虑。空气室下体采用ABS材料成型,压力较大,但用楔紧块保证了空气室下体模具的可靠性。

ABSTRACT
The main frame of the lower body of the air chamber is a revolving body with moderate size and complex structure. In order to mass production of this product, in the process of the injection molding products parts decided need with side core pulling mechanism, dynamic mould opening process in the slanting guide pillar drives the sliding block to slide in order to achieve lateral core pulling and opening force releasing action. The push rod in the mold after parts of the push rod under the action of. After considering the part can be applied to a mold two cavity, the gating system is designed with the potential gate, and the shunt channel, etc.. Should part size is high, in order to avoid opening stroke can not meet the requirements to take the way of pouring hot runner. Because of the gap between the push rod and the parting surface, there is no need for additional design of exhaust system. The lower body of the air chamber is made of ABS material, the pressure is large, but the wedge block ensures the reliability of the lower body of the air chamber. [来源:http://Doc163.com]
