摘要： Apparatus for forming in one operation a molded article having box-like sides such as a concrete meter box, and a molded covering lid therefor. A cavity in the shape of connected sides of a box is formed between an inner form and a surrounding outer form. An open top lid form rests on the top of the inner form, its outside surface extending out beyond the top of the inner form to define a shoulder and an upper extension of the cavity. The cavity and the lid form are filled with a settable material and vibrated. A power unit then raises the box-like article by engaging a pallet beneath the article at the bottom of the cavity, the box-like article being capable of carrying the lid form upwardly with it by engagement of the finished article with the shoulder of the lid form.
