Problems solved by technology

[0003] The hot pressing mold installed on the pulp forming equipment transfers a large amount of heat to the pulp forming equipment while the paper embryo is pressure dried and shaped, resulting in heat loss and thermal deformation of the equipment, and the thermal deformation of the equipment causes the equipment to run up and down Misalignment of the mold
In order to solve the thermal deformation of the equipment caused by the heat transferred to the equipment, there are currently high-pressure pressed asbestos and glass fiber insulation boards installed under the hot pressing die (or hot pressing die with a heating plate), but under high temperature and high pressure The lower heat resistance effect is not ideal. There are also metal cooling water plates installed under the hot pressing die (or hot pressing die with heating plate). Take away a lot of heat energy and power loss of cooling water device
[0004] The hot-pressing mold installed on the pulp forming equipment is drying and shaping the paper embryo under pressure. The equipment bears the pressure of 0.5-1MPa on the mold paper embryo and the error of equipment processing and manufacturing. The equipment produces mechanical deformation, and the deformation of the equipment causes hot pressing. After the upper and lower molds are closed, the gap between the molds is inconsistent, resulting in the scrapping of paper embryo products, especially for paper mold forming equipment with a large worktable.

Description

technical field [0001] The invention relates to a paper mold forming equipment with self-adjustable thermal resistance. It belongs to the technical field of paper mold forming equipment. Background technique [0002] The forming principle of paper mold forming equipment is to use the mold equipped with wire mesh to vacuum absorb and form the pulp diluted to a moisture content of 3-5‰, and transfer the molded paper embryo with a moisture content of 65-75% to 110-200°C Pressure drying and shaping in the hot pressing mold. The heating structure of the hot pressing mold is formed by installing a heating carrier in the mold or combining the mold with a heating plate with a heating carrier. The mold and the heating plate for heating the mold are made of alloy aluminum, alloy copper, stainless steel and alloy steel. [0003] The hot pressing mold installed on the pulp forming equipment transfers a large amount of heat to the pulp forming equipment while the paper embryo is press...
