二背景技术Two background technology

In order to increase the performance strength and connection requirements of foamed products, it is usually necessary to pre-embed various inserts and inserts during the product molding process. Positioning is an essential part of the mold structure.
目前高分子及其复合材料发泡成型嵌件定位装置或采用磁铁吸附嵌件的方法，磁铁吸附嵌件在发泡成型力的作用下嵌件容易产生侧向移动而偏离原来的定位位置，嵌件异位造成大量产品不合格甚至报废，经济损失巨大，或在嵌件上附加外力使之固定。如专利号为201010209559.7的专利公开的是注塑模具中用于嵌件定位检测的结构，嵌件需要在外加力作用下与定位柱始终接触提供行程开关信号，从而导致定位柱卡在塑料件中，定位柱会与注塑件固结在一起，只能沿定位柱轴线方向强制开模。At present, the positioning device for foam molding inserts of polymers and their composite materials or the method of magnet adsorption inserts, the magnet adsorption inserts are prone to lateral movement and deviate from the original positioning position under the action of foaming force. The dislocation of the parts causes a large number of products to be unqualified or even scrapped, resulting in huge economic losses, or an external force is added to the insert to fix it. For example, the patent No. 201010209559.7 discloses a structure for insert positioning detection in an injection mold. The insert needs to be in constant contact with the positioning column to provide a travel switch signal under the action of an external force, which causes the positioning column to be stuck in the plastic part. The positioning column will be consolidated with the injection molded part, and the mold can only be forced to open along the axis of the positioning column.
