Problems solved by technology

In this molding method, because the mold core is inserted into the aggregate while it is in a stationary state, the front part of the mold core with most of the pressure is pressurized, which may easily cause the density of the hollow block to be uneven and cause poor quality. Effect
Especially in the manufacture of hollow blocks of organic aggregates, due to the fast solidification speed, the aggregates and the mold cores are easily bonded to form a dead mold phenomenon, and the formwork is also easy to bond with the aggregates, resulting in difficulty in demoulding. This molding method is not only low in product quality, but also low in production efficiency

Embodiment Construction

[0008] Such as figure 1 In the compression molding machine shown, the motor drives the transmission gear box 1 to move, so that the screw 7 rotates to drive the pressure beam 4 to move up and down. The box 3 and the mold 9 are installed on the mold rotating disk 5 below the mold core 6, and the mold rotating disk 5 can rotate around the column guide rail 8.

[0009] Such as figure 2 In the core reduction box 3 shown, the six cores 6 are connected with the six transmission gears 11 in the core reduction box 3 respectively. This connection is connected by welding with the connecting shaft 14, and thread Screw mode is connected with connecting shaft 14. Transmission gear 11 is connected with driving gear 10, and driving gear 10 is driven by bevel gear 13 by gear reducer 12, and gear reducer (12) is driven by motor.

[0010] The quantity of mold core 6 and transmission gear 11 will be determined according to the model of the hollow block that is pressed, and the rotation direc...

Abstract

A die pressing technology for manufacturing hollow building block features that in the pressing procedure, the die core is always rotating, resulting in uniform compactness, easy demoulding, and high quality and productivity of products.

Description

technical field [0001] The present invention relates to a method for the manufacture of hollow blocks for construction, and in particular to a method of molding hollow blocks. Background technique [0002] In the process of manufacturing hollow blocks for construction, it must go through the molding process. The existing molding method for manufacturing hollow blocks is to squeeze the core on the compression molding machine vertically or laterally into the mold under mechanical action. , so that the stirred aggregate is extruded in the mold and solidified to make a hollow block. In this molding method, because the mold core is inserted into the aggregate while it is in a stationary state, the front of the mold core with most of the pressure is pressurized, which may easily cause the density of the hollow block to be uneven and cause poor quality. Effect. Especially in the manufacture of hollow blocks of organic aggregates, due to the fast solidification speed, the aggregat...
