Forming and demoulding mechanism of chuan-shaped pallet mould with cross-inclined roof includes upper and lower plate, upper and lower plate with runner plate, runner plate with runner rack, runner plate with cavity plate, lower plate with mould foot, lower and upper plate between mould foot, mould foot with mould core plate and core insert on mould core plate. A cavity is formed between a block, a core insert and a cavity plate, in which there is an injection molded tray, a long slider and a short slider core pulling structure are arranged on the four sides of the core plate, a steel pipe insert is arranged in the core plate, a steel pipe insert is arranged in the steel pipe insert, a full grid insert is arranged in the cavity plate corresponding to the steel pipe insert, and a full grid insert is arranged in the cavity plate corresponding to the steel pipe insert. A full-grid die cavity is arranged in the block, and two crossed oblique ejector bars are connected on the upper roof plate, and two oblique ejector bars pass through the core plate. Each oblique ejector block is arranged at the head of the two oblique ejector bars. The two oblique ejector blocks are symmetrical to each other and are coated on the steel pipe insert, and the top surfaces of the two oblique ejector blocks and the full-grid insert constitute a full-grid die cavity.

川字型托盘模具交叉斜顶成型脱模机构
本技术涉及一种川字型托盘模具交叉斜顶脱模机构,属于注塑模具领域。
技术介绍
在仓储、运输等过程中,需要用到塑料托盘来承载物品,受到普遍使用。塑料托盘的结构有多种,例如川字型托盘、田字型托盘等。已有的川字型托盘如中国专利ZL201520282580.8授权文本所公开,上筋板和下筋板先分体制造,然后通过焊接或者卡扣连接,这种托盘生产工序多,制造成本高。为提高效率,降低成本,本申请人曾经专利技术了上下筋板整体成型的托盘,这种托盘降低了产品成本,但受脱模因素制约,上筋板位于与下筋板对应的区域只能制成对插结构。经市场反馈,对插结构的托盘比较脆弱,容易断裂,承载力有限。
技术实现思路
本技术的目的是为了克服已有技术的缺点,提供一种采用交叉斜顶结构,使托盘既能采用全网格结构,又脱模顺利的川字型托盘模具交叉斜顶成型脱模机构。本技术川字型托盘模具交叉斜顶成型脱模机构的技术方案是:包括模具上复板和下复板,上复板下安装流道板,流道板中安装流道架,流道板下安装型腔板,下复板上安装模脚,模脚之间设置下顶板和上顶板,模脚上安装型芯板,型芯板上设置型芯镶块,型芯镶块与型腔板之间构成模腔,模腔中有注塑成型的托盘,在型芯板的四侧设置长滑块和短滑块抽芯结构,其特征在于所述的型芯板中设置钢管镶块上,钢管镶块中设置钢管,在与钢管镶块对应的型腔板中设置全网格镶块,全网格镶块中设置全网格模腔,所述的上顶板上连接两根交叉的斜顶杆,两斜顶杆穿过型芯板,在两斜顶杆的头部各设置斜顶块,两斜顶块互相对称,并包覆在钢管镶块上,且两斜顶块的上顶面与全网格镶块构成全网格模腔。本技术的 ...
