Demolding and die closing device for wood particle reinforced composite floor die

Technical Field

The utility model relates to the technical field of reinforced floor production, in particular to a demolding and mold closing device for a wood particle reinforced composite floor mold.

Background

The railway flatcar is used as one of four large railway freight cars in China, the market application is wide, and the wood floor for the railway flatcar is used for being padded and protected on the flatcar to protect the flatcar from being damaged by goods, so that the requirement of the wood floor for the railway flatcar on strength is far higher than that of the common wood floor.

The wood particle reinforced composite floor is a novel board for railway flatcar researched by China railway science institute group, namely metal and chemistry research institute, and consists of a bearing layer, a reinforcing layer and an elastomer, and the wood particle reinforced composite floor replaces the traditional wood floor for railway flatcar, so that the service life of the railway flatcar can be greatly prolonged, and the maintenance period can be prolonged.

The traditional wood particle reinforced floor molding process is as follows: 1. spraying a release agent in the mould, and paving a reinforcing layer at the bottom of the mould so as to increase the strength of the floor; 2. putting foaming materials mixed by wood particles and polyurethane foaming materials on the reinforcing layer; 3. spraying an elastomer on the foaming material; 4. and combining an upper die, a middle die and a bottom die on the die, and sending the assembled die into a drying tunnel for heat preservation and solidification.

The process of combining or disassembling the upper die, the middle die and the bottom die on the die is as follows: and (3) lifting the upper die of the forming die away from the assembled middle die and bottom die by using a crown block, injecting the stirred anti-corrosion wood particles and polyurethane foaming materials into the assembled middle die and bottom die, putting down the upper die by using the crown block, centering and closing the dies, pressing, preserving heat and solidifying materials in the dies, transferring the dies to a demoulding station by using a forklift after the floor in the dies is formed, lifting the middle die to a demoulding tool after lifting the upper die by using the crown block, removing the floor in the middle die, and then sequentially assembling the middle die and the upper die with the bottom die and then transferring the forklift to a floor pressing line for pressing and forming a new product.

After the molds are combined, the molds are kept warm in the drying tunnel for a plurality of hours, so that in actual production, the molding molds enter and exit the drying tunnel in batches in the heat preservation and curing process, therefore, the molds are assembled in a short time, a certain amount of molds are quickly stored, and then the molds are sent into the drying tunnel together, so that the highest efficiency can be achieved; therefore, the efficiency of die assembly and die disassembly is improved, the production efficiency of the heat preservation solidification process can be maximized without the condition of empty die transportation caused by low die assembly and die disassembly efficiency, and the die assembly and die disassembly device used in the existing molding process has the following defects:

1. the crown block is a lifting device with higher universality in factories, has huge volume and slower equipment operation, and does not have a grabbing mechanism specially adapted to the mould for producing the wood particle reinforced floor, so the working efficiency of the mould lifting process is lower;

2. only one lifting device is used for processing one die at a time, namely, after one die is completely demoulded, the demoulded die is assembled and conveyed to a floor pressing line to produce floors, and the whole operation process has no continuous production by mutually matching a plurality of devices, so that the labor efficiency is low, the process route is long, and mass production cannot be realized.
