The utility model discloses an acceleration ejection device for an injection mold, which comprises a forking board, a top rod, a pin shaft and a push rod. One side of the forking plate is opened with an open half hole and a slot is provided on the side, a half hole is connected with a slot, and a staircase hole or a ladder slot is opened on the other side of the forking board; the lower end of the top rod is worn through the other side; the lower end of the top rod passes through the bottom. The bottom end of the rear end of the half hole on the side of the forking plate is located in the slot, and the upper end of the top rod can enter the type cavity; the lower end of the push rod is mounted on the other side of the forking plate, the upper end of the push rod can be mounted on the top of the fixed plate of the movable mold; the two sides of the pin can be fixed vertically on both sides of the forking plate, and the pin can be movable in the thimble plate. The utility model is mainly composed of several parts, such as the upside board, the top rod, the pin shaft, the push rod and the like, and the structure is very simple, and the utility model uses the push rod to push the top board, so that the board is swinging around the pin shaft and then pushing the top rod out of the injection product, and the action is stable and reliable.
【技术实现步骤摘要】
注塑模具加速顶出装置
本技术涉及一种注塑模具,特别是涉及一种注塑模具加速顶出装置。
技术介绍
塑料注塑模具是生产塑料制品的工具,应用非常广泛。顶出机构是注塑模具基本部件,为了提高生产效率,需要加快注塑产品的顶出过程,为此,业者需要设计出一种可加快产品顶出的机构。
技术实现思路
本技术的目的在于提供一种结构简单、动作稳定可靠的注塑模具加速顶出装置。为实现上述目的,本技术的技术解决方案是:本技术是一种注塑模具加速顶出装置,包括翘翘板、顶杆、销轴、推杆;所述的翘翘板的一侧开设有敞开的半孔且在该侧设有缺槽,半孔与缺槽连通,在翘翘板的另一侧开设有阶梯孔或阶梯槽;所述的顶杆的下端穿过翘翘板一侧的半孔后顶杆下端的沉头坐落在缺槽内,顶杆的上端可输入型腔;所述的推杆的下端顶靠在翘翘板另一侧,推杆的上端面可与动模固定板顶靠;在翘翘板的两侧分别垂直固定一销轴,该销轴可活动安装在顶针板内。所述的推杆的下端具有沉头。采用上述方案后,由于本技术主要由翘翘板、顶杆、销轴、推杆等几个部件构成,结构十分简单,且本技术是利用推杆推顶翘翘板,使得翘翘板围绕销轴摆动进而推顶顶杆顶出注塑产品,动作稳定可靠。下面结合附图和具体实施例对本技术作进一步的说明。附图说明图1是本技术的轴测图;图2是本技术安装在注塑模具中的正视图;图3是安装有本技术注塑模具开始的顶出状态图;图4是安装有本技术注塑模具顶出完成后的顶出状态图。具体实施方式如图1所示,本技术是一种注塑模具加速顶出装置,包括翘翘板1、顶杆2、销轴3、推杆4。所述的翘翘板1的一侧开设有敞开的半孔11且在该侧设有缺槽12,半孔11与缺槽12连通,在翘翘板1 ...
