Description

一种靠滑块镶件斜抽的机构脱出塑料制品的模具A mold that ejects plastic products by the mechanism of oblique drawing of slider inserts

技术领域 technical field

本发明属于热塑性塑料成型模具领域，涉及一种靠滑块镶件斜抽的机构脱出塑料制品的模具，主要应用于产品内腔里有斜槽倒扣的模具中。 The invention belongs to the field of thermoplastic molding moulds, and relates to a mould, in which plastic products are released by a mechanism of oblique drawing of slider inserts, and is mainly used in molds with chute undercuts in product inner cavities.

背景技术 Background technique

目前对于产品内腔里有斜槽倒扣的模具，一般采用动模斜芯子先抽机构来实现，此种机构动模斜芯子穿过动模板固定在动模垫板上，动模板和动模垫板之间有弹簧和导柱，动模板为浮动的板，动模斜芯子与固定在动模板上的动模镶块斜面配合并可以滑动，利用斜芯子的头部成型产品的斜槽部分；开模时，在弹簧的作用下动模板由导柱导向与动模垫板最先分开，动模斜芯子随同动模垫板一起运动，沿斜面滑出脱出产品内腔的斜槽倒扣。此种机构需要多增加一块动模垫板，占用模具空间大，提高了模具的制造成本；动模斜芯子与动模镶块滑动配合要求公差严，使加工过程难度增大；动模斜芯子与动模镶块接触面积大，在成型量产时容易拉伤；由于动模斜芯子穿过动模板固定在动模垫板上，在钳工装配时需要大量时间调配，增加了劳动量。 At present, for molds with chute undercuts in the inner cavity of the product, it is generally realized by the first-drawing mechanism of the movable mold inclined core. In this mechanism, the movable mold inclined core passes through the movable template and is fixed on the movable mold backing plate. The movable template and There are springs and guide posts between the movable mold backing plates, the movable mold plate is a floating plate, the inclined core of the movable mold cooperates with the inclined surface of the movable mold insert fixed on the movable mold plate and can slide, and the product is formed by the head of the inclined core The chute part of the mold; when the mold is opened, the movable mold plate is guided by the guide column and the movable mold backing plate is separated first under the action of the spring, and the inclined core of the moving mold moves along with the moving mold backing plate, and slides out of the inner cavity of the product along the inclined surface The chute is undercut. This kind of mechanism needs to add an additional movable mold backing plate, which occupies a large mold space and increases the manufacturing cost of the mold; the sliding cooperation between the movable mold oblique core and the movable mold insert requires strict tolerances, which increases the difficulty of the processing process; The contact area between the core and the movable mold insert is large, and it is easy to be strained during mass production; since the inclined core of the movable mold passes through the movable template and is fixed on the movable mold backing plate, it takes a lot of time to adjust when the fitter assembles, which increases labor quantity.
