A fixing device for box culvert mould and vibration table suitable for producing square culvert products

Abstract

The invention relates to a fixing device for a die and a vibration table, in particular to a fixing device for a box culvert die and a vibration table suitable for producing square culvert products. The fixing device aims at solving the problems that due to the adoption of an existing connection manner, the production efficiency is low, production of the square culvert products is affected, and potential safety hazards exist. The upper portions of box culvert outer die bodies are connected with box culvert outer die expansion blocks through upper clamping oil cylinders; the lower ends of box culvert inner die bodies and the lower ends of the box culvert outer die bodies are arranged on a box culvert bottom support through cooperation of pins and pin holes; two connecting beam assemblies are symmetrically fixed to the vibration table, and the box culvert bottom support is fixed to the connecting beam assemblies; and the vibration table is further provided with a plurality of hydraulic clamps, and clamping discs of the hydraulic clamps and the box culvert outer die bodies are clamped together. According to the fixing device, the box culvert die connection manner is reliable, and the movement cannot happen; meanwhile, potential safety hazards are prevented from happening in the production process; and the box culvert outer die bodies are fixed and clamped through the connecting beam assemblies and the hydraulic clamps on the vibration table, and the clamping force is uniform and is continuous in the whole production process.

Description

technical field [0001] The invention relates to a fixing device for a box culvert mold and a vibrating table. Background technique [0002] At present, the more common way of fixing box culvert molds in China is: the lower end of the outer mold and the mold frame seat are connected by a telescopic hinge rod, and the inner mold is hinged to the mold frame seat with hinge ears at the lower end. Although this method can solve the problem of mold and mold The connection of the vibration table, but the outstanding problem is: [0003] 1. When producing molds of different specifications and models, the unit replacement time of molds is longer, especially in mass production, which will seriously affect the production progress; [0004] 2. Due to the large excitation force of the square culvert vibrating table, in this case, the hinge mode is prone to loosening, which will cause the inner and outer molds to shift on the vibration table, affect the production of square culvert produ...

AI Technical Summary

Problems solved by technology

[0003] 1. When producing molds of different specifications and models, the unit replacement time of molds is longer, especially in mass production, which will seriously affect the production progress;

[0004] 2. Due to the large excitation force of the square culvert vibrating table, in this case, the hinge mode is prone to loosening, which will cause the inner and outer molds to shift on the vibration table, affect the production of square culvert products, and even cause hinge failure , so that the inner and outer molds fall off from the vibrating table, causing serious production accidents
