Abstract
The utility model relates to a hot pressing forming mould for producing moulding wood manufactured products in the wood processing technique. The utility model which is designed refers to the problems of the bubbling, the combination edge error, the buckling deformation, etc., for the moulding manufactured products in existence. The mould adopts a composite structure. The utility model has the advantages of low cost and convenient replacement. In the process of using for adjusting and repairing, the mould has better function of discharging the steam. The combination edge quality of the manufactured product is good, and the larger breadth face manufactured product generated by a pressing machine with smaller tonnage is achieved.
Description
The utility model relates to the heat pressing and molding mold of production mold pressing woodwork in a kind of heat pressing and molding mold, particularly wood processing technique.
At present, that production compression molding goods adopt in the wood working industry both at home and abroad is plane pressurization ┈ Wei Erchailitefa, and heat pressing and molding mold is the equipment of most critical during the mold pressing woodwork is produced, and the quality of its performance directly affects Products Quality and cost.
Existing heat pressing and molding mold adopts planar design, and straight flange is made at the edge of formpiston front matched moulds periphery, requires press tonnage height in production mold pressing woodwork process, the product edges difficult treatment, thus improved production cost.Steel pricker quantity is few on the formpiston, the steel pricker exhaust hole has only the individual layer passage, the formpiston position is following, the moisture discharge direction down, the moisture discharge resistance is big in the production process, efficient is low, this just requires the wood particulate moisture content to be controlled at below 3%, so that the dry run investment is big, energy resource consumption is high, and goods generation bubbling is scrapped, operating difficulties, and the wood particulate moisture content is low excessively, can make mobile the reduction again, and steel pricker is arranged inhomogeneous, moisture discharge is inhomogeneous, causes product deformation.Mould adopts whole processing and fabricating to form, and cost of manufacture is high, adjustment in the use, maintenance, replacing process complexity.
The purpose of this utility model be overcome above-mentioned deficiency of the prior art and provide a kind ofly make the mold pressing panel heat pressing and molding mold simple, that cost is low, easy to use.
To achieve these goals, the technical solution that the utility model provides is: formpiston adopts the variable cross-section moulding, and the backrest slope is made at the edge of formpiston front matched moulds periphery, and steel pricker quantity only is increased to 8--30.
In order to reach better effect, the utility model is arranged the steel pricker on the formpiston evenly, steel pricker is provided with double-deck passage, steel pricker quantity is controlled between the 8--12, exchanges the matched molds position, and formpiston is last, former is following, mould is a fabricated structure, adopt the common low carbon steel plate to engage and form, and the former inner chamber is processed by corrosion resistant plate.
Mold pressing panel heat pressing and molding mold compared to existing technology the utlity model has following advantage:
＜1〉realized less tonnage press production than the large format goods, and product edges is easy to handle;
＜2〉strengthened the moisture discharge function, improved moisture discharge efficient, wood particulate only need get final product through the air-dry or preliminarily dried of atmosphere, simplified dry run, its moisture content can be up to 12%, and the raising of particle moisture content can make glue mixing more even, and particle is mobile better under certain pressure, helps improving the quality of product;
＜3〉disperse the thermal stress of goods effectively, improved non-deformability, reduced the warpage of goods;
＜4〉mould adopts the common low carbon steel plate to engage to form, corrosion resistant plate on former inner chamber lining, and the processing of corrosion resistant plate inner chamber does not need the special steel punch die, processes simple and easyly, and adjustment in the use, maintenance, replacing process are simple and easy to do;
＜5〉simplified production process, reduced requirement, reduced the energy resource consumption in the production process significantly, the corresponding production cost that reduced equipment.
To tie accompanying drawing below essentiality content of the present utility model and characteristic will be done further detailed description.
Fig. 1 is the mold sections schematic diagram
Fig. 2 is a mold pressing panel schematic cross-section
Accompanying drawing 1 is an embodiment of the utility model mold pressing panel heat pressing and molding mold.It is made up of formpiston (1) and former (2), mould adopts cheap common low carbon steel plate to engage and forms, backrest slope (4) is made at the edge of formpiston (1) front matched moulds periphery, being equipped with nine on formpiston (1) has the steel pricker (3) of double-deck passage (6) (7) and is evenly and arrange, at smooth, hard, the wear-resisting inner chamber (5) of former (2) liner upper surface, inner chamber (5) is processed under the situation that does not need the special steel punch die by corrosion resistant plate.Formpiston (1) adopts the variable cross-section moulding.Fig. 2 is a mold pressing panel schematic cross-section, and goods can be divided into inner ring (8), centre circle (9), and trim ring is waited in (10) three of outer rings, the suffered unit pressure minimum of inner ring (8) wherein, centre circle (9) takes second place, the unit pressure maximum that outer ring (10) are suffered.When the mould heat pressure moulding was closed, the engagement place of negative and positive mould produced fierce friction, and the particle that outer ring (10) is comprised is subjected to strong friction and extruding, thereby made goods form very closely knit periphery, had improved greatly and had closed the limit quality.In the hot-forming process, the mould force part mainly concentrates on centre circle (9) zone, and the bearing area of visible centre circle (9) can be used as the basic parameter of selecting the press tonnage, thereby the production of less tonnage press is become a reality than the large format goods.Big more its mechanical property of the density of goods is good more, also easy more buckling deformation.Reduce the density of goods in inner ring (8) zone of area maximum, can not only improve the anti-warpage performance of goods, and this regional thickness increases the also corresponding mechanical property that improves goods, the equally distributed bellmouth (11) that is squeezed into by steel pricker (3) has the effect of dispersive stress in inner ring (8) zone, thereby further controls the buckling deformation of goods.
Claims (6)
1, a kind of mold pressing panel heat pressing and molding mold, it comprises formpiston and former, on formpiston, be provided with the steel pricker that is used for vent water vapor, feature of the present utility model is that formpiston (1) adopts the variable cross-section moulding, backrest slope (4) is made at the edge of formpiston (1) front matched moulds periphery, and steel pricker (3) quantity is 8-30.
