Abstract

PURPOSE:To achieve the labor saving by making the work to clamp and release a mold when molding a concrete block. CONSTITUTION:A concrete block molding device is so constituted that molding frames arranged on a base are clamped to form a finished product, then the clamping is released to part a molding from the mold. In this device, an engagement receptive part 57 is formed on one 31 of mutually opposed right/left lateral molding frames 30, 31, and a turning shaft is axially supported on the other lateral molding frame 30. In addition, the base end part of a rod 4 with an engagement element which engages with the engagement receptive part 57 for engagement formed, is axially attached to an eccentric shaft part 44 formed on the turning shaft, and the clamping and releasing of the mold is performed by rotating the turning shaft. Further, a curved part 47 is formed on the base end part of the rod 45, and the turning shaft can be rotated to a position where a line of force connecting the center of the eccentric shaft part 44 to the center of an engagement part exceeds the shaft center of the turning shaft, in a state that the engagement part is engaged with the engagement receptive part 57.

る。In order to improve the manufacturing efficiency, a plurality of bottom molds for two blocks are arranged in a rectangular shape, and a partition plate is erected at the boundary of each mold to mold a plurality of blocks at the same time. In order to facilitate the assembling and disassembling of the formwork, the lower end portions of the side surface formwork erected around the bottom formwork are rotatably pivoted to the lower part of the bottom formwork, and the opposite side surfaces are supported. Some molds are clamped by a mold clamp mechanism to form the whole mold, and after the mortar is cast and cured, the above clamps are released to separate the side mold from the product. For clamping the formwork, the formwork clamp mechanism attaches one end of the chain to one side formwork upper end of one of the two sideface forms facing each other and the other end of the chain to the other sidework form. It is attached to the upper end via a toggle mechanism, and by the action of the toggle mechanism, the formwork is Tightening, and to perform the release.

In order to solve this, frequent chain length adjustments are required and the handling is troublesome, and the side formwork can be opened only by the stroke of the toggle. Since the chain attached to the upper end of the mold is suspended above the product, there is a problem that it interferes with product removal.

Interference of the rod 45, the center 79 of the locking body 49 of the rod 45 and the center of the eccentric shaft 44
The eccentric shaft portion 44 can be rotated until the line of force L connecting to the shaft 78 is located above the axis 58 of the rotary shaft 42. In this state, the inner edge of the bending portion 47 rotates. The rotation is restricted by contacting the outer peripheral surface of the moving shaft 42. At this time, since the upward rotation force is applied to the eccentric shaft portion 44, the rotation shaft 42 does not rotate in the opposite direction, and thus the mold clamping state can be maintained.
