摘要： Apparatus for molding blocks with laterally projecting, undercut side features includes a mold box having split mold parts defining a mold cavity open at the top and bottom. A top plate having an opening aligned with a cavity overlies the mold parts. Moldable block material is charged into the cavity from a feed box, and the material is compacted and shaped between a lower pallet and upper stripper head. The mold parts are retractable beneath the top plate to release the block for stripping through the bottom of a mold. A plurality of fluid outlets in the top plate cleanse the mold surfaces of the block material between mold cycles.

摘要： Apparatus for molding blocks with laterally projecting, undercut side features includes a mold box having split mold parts defining a mold cavity open at the top and bottom. A top plate overlies the mold parts and is formed with an opening aligned with a cavity. Moldable block material is charged into the cavity from a feed box, and the material is compacted and shaped between a lower pallet and upper stripper head which are moved to close the bottom and top of the cavity during vibration of the mold. The mold parts are retractable beneath the top plate to release the block for stripping through the bottom of a mold. A plurality of fluid outlets in the top plate communicate with problem areas of the recessed mold parts which are prone to accumulate residual block material. Pressurized clean-out fluid, such as air is directed through the outlets onto such problem areas to cleanse the mold surfaces of the block material between mold cycles. An air knife is carried by the feed box and directs a high pressure curtain of air against the underside of the stripper head to remove any accumulated block material therefrom during movement of the feed box into and out of position over the mold.

摘要翻译： 用于模制具有侧向突出的切削侧部特征的块的装置包括具有限定在顶部和底部开口的模腔的分开的模具部分的模具箱。 顶板覆盖在模具部件上并形成有与空腔对准的开口。 可模塑块材料从进料箱装入空腔中，并且材料被压实并成形在下部托盘和上部剥离器头之间，在下部托盘和上部剥离头之间移动以在模具振动期间关闭空腔的底部和顶部。 模具部件在顶板下方可收缩以释放块以通过模具的底部剥离。 顶板中的多个流体出口与凹陷的模具部件的易于积聚残留块材料的问题区域相通。 诸如空气的加压清洁流体通过出口引导到这样的问题区域上，以在模具循环之间清洁块材料的模具表面。 气动刀由进给箱承载，并将高压的空气帘子引导到汽提头的下侧，以在进给箱进入和离开模具的位置移动期间从其中去除任何积聚的块材料。
