Abstract

The invention provides a foam model bonding machine for lost foam casting. The foam model bonding machine comprises an upper model box and a lower model box, the lower model box is fixed to a worktable, a glue brushing pool is fixed to the worktable, a model box conveying mechanism is connected to the worktable through a bracket, the upper model box is clamped through a box-type fixture and then suspended on the model box conveying mechanism, and the upper model box is driven by themodel box conveying mechanism to move between the upper part of the lower model box and the upper part of thegluebrushing pool. Compared with the prior art, the foam model adhesive machine for lost foam casting has the beneficial effects that overall design is simple, integration of glue brushing, assembling and shaping of a foam model is realized, and the foam model adhesive machine has the advantages of high assembly and bonding accuracy and high speed, the bonding requirements of foam models with different shapes can be met, and the problems of low efficiency, poor quality stability, and uneven glue application in the process of glue brushing as well as the problem ofbonding precision of the upper and lower foam models are solved.

Description

technical field [0001] The invention relates to a foam bonding machine, in particular to a foam model bonding machine for lost foam casting. Background technique [0002] Lost foam casting is an important precision casting molding technology, which has an irreplaceable position in industry and other fields. At present, my country's lost foam casting industry is developing rapidly and on a huge scale. [0003] The foam model for lost foam casting is a combination and bonding of patterns made of foamable polymethyl methacrylate and polystyrene. When each casting is cast, the model is melted, burned and vaporized by high-temperature molten metal, and the molten metal occupies The original space is solidified and cooled to form a casting. Among them, the assembly accuracy of the foam model is a key factor affecting the quality of the casting. However, the current assembly process of the foam model for lost foam casting mostly uses manual glue brushing and manual bonding. conduc...
