The injection mold plastic parts within the walls of square buckle demoulding mechanism, including upper and lower plate, on the plate under the cavity under the plate arranged on the core and the upper and lower cylinder, the top block set on the core, the upper and lower cylinder piston rod is connected with the top of the block, the top block is arranged on the front and rear, the left and right inner core pulling slider respectively by pulling cylinder in the mold cavity, a square plastic piece around under vertical flanging, made in flanging buckle, which is characterized in that the front and rear, left and right inner core pulling slider respectively with square plastic parts four angle corresponding to the core. For rectangular pumping core, pumping core front and rear sides of the short side and front and rear inner core pulling slider contact, and before and after the inner core pulling slider is less than the width of pumping short side column width in the column on both sides of the long side pumping and the left and right inner core pulling the slider contact, and left and right in the core pulling slider width is greater than in The long side pumping core width, the left and right sides of the inner core pulling slider long stem long side part respectively before and after the convex block and the inner core pulling the slider contact on both sides. The product rate of the product is high and the production efficiency is improved.

注塑模具方形塑料件四壁内倒扣脱模机构
本技术涉及注塑模具,特别是涉及注塑模具方形塑料件四壁内倒扣脱模机构。
技术介绍
在注塑模具中,若塑料件四壁分别制有向下的翻边,且四壁的翻边制有向内的倒扣,已有技术通常是将倒扣的宽度做小,厚度做薄,利用塑料件的弹性,采用强脱的方式进行脱模,这样导致塑料件位于倒扣位置在脱模时容易被拉断,从而影响产品的成品率,因此本专利技术人曾申请了中国专利技术专利201510302244.X,专利名称为“注塑模腔体件内环形倒扣脱模机构”,其包括滑座中设支撑柱,主型芯与支撑柱相固定,滑座外侧安左、右、前、后油缸,滑座上制左右滑轨和前后滑轨,型芯包括主型芯下设左、右、前、后内抽芯,主型芯与支撑柱连接,左、右、前、后内抽芯分别与塑料件的内环形倒扣配合,该结构存在的缺点是:一、仅适用于脱圆环形的塑料件;二、由于支撑柱上连接主型芯,因此要将塑料件的翻边向外侧倾斜,且倾斜角度要较大,才能使塑料件脱模时能够脱出主型芯。
技术实现思路
本技术的目的是为了克服已有技术存在的缺点,提供一种有利于四面翻边垂直向下的内倒扣方形塑料件脱模,成品率高,提高生产效率的注塑模具方形 ...
