Description

A kind of bamboo and wood plate forming heating and cooling mould

technical field

The utility model relates to a heating and cooling mould for forming a bamboo and wood plate, which belongs to the field of bamboo and wood processing.

Background technique

Compression molding technology is widely used in the field of plastic product molding and is by far the most common means of manufacturing plastic products. Compression molding is also used in the manufacture of ordinary wood panels, but as far as the heating molds currently on the market are concerned, the heating, heat preservation and cooling properties of the molds are not particularly suitable for the production of wood panels. The appearance, performance and production efficiency of finished wood panels molded using traditional heated molds cannot be mass-produced. The traditional heating mold is heated by electric heating wire, that is, the electric heating wire is cast into the mold for heating. In recent years, electric heating plates and electric heating coils are more commonly used for heating. The common problems of the two are that the heat utilization rate is low, the heating time required for the mold is too long, and the wood products cannot obtain a constant thermal insulation effect during the heating process, which leads to a large reduction in the performance of the wood products in all aspects. Less than the desired product quality. The electric heating coil has the problem of excessive heat loss and high production cost. To sum up, in the production process of mass wood products using the existing heating molds, the quality of wood products is reduced due to the insufficient thermal insulation performance of the molds.

The upper die body (3) has a water inlet 1 (12) and an oil outlet (11) on the right side, and a corresponding oil inlet 1 (13) and a drain outlet 1 (14) on the left side. There are the same S-shaped arrangement of water condensation grooves (7) and double S annular sealing grooves 1 (8) under the main body (3) of the upper mold and above the partition plate (4). ) and the sealing gasket (6), and the water condensation pipe 2 (24) communicates with the water inlet 1 (12) and the water outlet (14) on the upper die body (3) respectively. There are the same S-shaped heat transfer oil heating groove (9) and double S annular sealing groove 2 (10) under the partition plate (4) and above the backing plate (5). 6), to prevent the liquid from flowing out, the two are fixed together to form a heat transfer oil heating pipe 2 (25) and a sealing gasket (6). The heat transfer oil heating pipe 2 (25) and the oil inlet 1 on the upper die body (3) (13) communicates with the oil outlet (11). The upper die main body (3), the partition plate (4), the backing plate (5) and the sealing washer (6) are fixedly connected by screws (23) into one body.

The lower mold includes a molding groove (15), a heat-conducting oil heating pipe 1 (16) and a water-condensing pipe 1 (17), and the heat-conducting oil heating pipe 1 (16) and the water-condensing pipe 1 (17) are arranged in an S-shape at the bottom. At the bottom of the mold, the heat-conducting oil heating pipe 1 (16) is close to the groove bottom of the molding groove (15). The lower mold is also provided with an oil inlet 2 (18), a water inlet 2 (19), an oil outlet (20) and a water outlet 2 (21). When the upper and lower molds are closed, the hot oil is injected into the oil inlet 1 (13) and the oil inlet 2 (18) with a heat transfer oil with temperature, and the upper mold backing plate (5) and the lower mold molding groove ( 15) The bottom is heated, and by applying downward pressure to the upper mold (1), the wood is heated and formed, and then the water condensing pipe 1 (17) is passed through the water inlet 1 (12) and the water inlet 2 (19). , The water condensation pipe 2 (24) is injected with circulating water to rapidly cool the upper and lower molds, so as to realize the heating and cooling molding processing of the wood board (22).

The utility model has the advantages of a heating and cooling mold for forming a bamboo and wood panel relative to the existing heating mold for molding wood products: the heat oil used in the heat-conducting oil heating method is input into the interior of the mold through a pipeline, and the hot oil is passed through the heat-conducting oil. The circulation inside the mold can greatly reduce the heat loss, make the mold heat up quickly, shorten the heating time, and the temperature is relatively stable, which can greatly improve the product performance. By controlling the temperature of the hot oil, the temperature accuracy of the product in the molding process is improved, and the cooling speed is increased by the water condenser, so that the production efficiency of the cold and heat cycle of the product is greatly improved.
