Manufacturing method for synthetic sole timber

Abstract

The invention relates to a manufacturing method and a special forming mold for a synthetic sole timber. The technological process of the manufacturing method is as follows: drying a powder lot or flaky material of imitation wood; adding a binding agent; stirring so as to prepare a synthetic sole timber raw material; extruding the raw material in the mold; performing compression moulding; heating; and demoulding and molding. The special mold comprises a fixed mould, a moving mould and an extrusion apparatus, wherein the fixed mould is composed of a mould bottom plate and two side plates which are fixedly connected with the mould bottom plate; the moving mould is composed of a press mold bottom plate with a longitudinal boss and a press mold upper plate with at least one transverse boss, and the end faces of the two side plates of the fixed mould are provided with moving end plates; and each moving end plate is provided with a pre-embedded positioning sleeve and a lock bolt, and the mould bottom plate is provided with at least one moving mould ejecting port. The manufacturing method and special forming mold provided by the invention have the advantages that the process of follow-up sawing is reduced due to once compression moulding of the synthetic sole timber manufactured by the process and the special mold, the time of a blank on a briquetting machine is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of production of synthetic skids for cargo storage and transportation, in particular to a production method of synthetic skids and a special forming mold thereof. Background technique [0002] In the logistics process, storage and transportation require dunnage for protection and packaging. The skids used to date for protection and packaging have been made of raw wood. Such skids are all disposablely consumed in the process of steel production, storage and transportation, resulting in the waste of a large amount of timber resources. According to international practice, the dunnage made of raw wood is required to be steamed and sterilized for export packaging to eliminate pests, which increases the cost of making dunnage and increases the storage and transportation expenses of articles. Along with the scarcity of forest resources, be badly in need of developing a kind of low price, many resources, easy to m...

Problems solved by technology

However, due to the large volume of large pads, it is difficult to remove the mold, the single-machine pressing or multi-layer pressing takes a long time, and the production efficiency is low. If you want to mass-produce, you must increase the number of presses, and the equipment cost is high; The four sides of the board must be sawed off, which not only causes a waste of raw materials, but also takes time and effort for the workers to operate; in addition, because the raw materials used in the production process of the plywood are various waste wood shavings, sawdust, straw, wheat straw, etc., which are added Some sundries such as stones and iron chips have been removed, so that in the process of dividing into small pieces of skids, the cutting equipment needs to be replaced frequently, and the noise is large; Digging some grooves, the process is complicated, and the labor intensity of the workers is high
