Abstract

Disclosed is a vertical inner cavity mold for manufacturing plywood. The mold is formed by multiple modules that are vertically arranged and removably connected to each other by using fasteners, and comprises a hanger-shaped central-ply flow channel and at least one hanger-shaped outer-ply flow channel. A feed port of the central-ply flow channel is provided at the center of one of two outer modules, a discharge port of the mold is provided at the center of the other outer module, and a feed port of the outer-ply flow channel is provided on at least one side in a horizontal direction of the mold and between two modules. The central-ply flow channel extends from the central-ply feed port to the discharge port; the outer-ply flow channel is vertical to the central-ply flow channel from the outer-ply feed port, extends between two modules, and wraps the central-ply flow channel, so that multiple outer-ply boards warp a central-ply substrate. The mold has a vertical inner cavity, and flow channels thereof are designed by intersecting upper and lower hangers and a horizontal hanger. Therefore, if being used to manufacture plywood with the same number of plies, the vertical inner cavity mold saves one module in comparison with a horizontal inner cavity mold, thereby saving the mold material and reducing the mold size.

Description

制造多层复合板材的立式内腔模具Vertical cavity mold for manufacturing multilayer composite sheets 技术领域Technical field
本发明涉及模具，更具体地，涉及一种制造多层复合板材的立式内腔模具。This invention relates to molds and, more particularly, to a vertical cavity mold for making a multilayer composite sheet.
背景技术Background technique
目前生产多层复合板材，通常是采用传统的挤塑工艺挤出单层板材，接着将单层板材均匀涂胶，然后采用诸如热压胶合的方法通过高温高压将多个单层板材粘合成多层复合板材。然而，这种挤塑成型工艺不能满足一些特定材料或特定功能多层板材的制作需要。此外，随着人们环保意识的增强，越来越需要无污染、安全的多层复合板材。传统加工工艺生产的多层复合板材的各层之间需要涂胶，而胶粘剂会散发有毒物质，从而污染环境且危害人的健康。At present, multi-layer composite sheets are produced, usually by extruding a single-layer sheet by a conventional extrusion process, then uniformly coating the single-layer sheets, and then bonding a plurality of single-layer sheets by high-temperature and high-pressure methods such as hot-press bonding. Multi-layer composite sheet. However, this extrusion molding process cannot meet the production needs of some specific materials or specific functional multilayer sheets. In addition, as people's environmental awareness increases, there is an increasing demand for multi-layer composite sheets that are free from pollution and safety. The layers of the multi-layer composite sheet produced by the conventional processing technology need to be glued, and the adhesive will emit toxic substances, thereby polluting the environment and endangering human health.
为了解决上述问题，近年来开发出能够实现通过一次注塑挤出成型形成多层复合板材而不需要添加任何胶粘剂的模具。In order to solve the above problems, in recent years, a mold capable of forming a multilayer composite sheet by one-shot extrusion molding without adding any adhesive has been developed.

One inner layer of the road and the intermediate portion is formed by a resin inlet flow path, two outer manifold portions long in the mold width direction, and an inner layer manifold portion, and the three inlet flow paths are formed to merge at the junction portion. Flow path shape. The mold disclosed in the Chinese patent is a horizontal cavity mold having three inlet flow paths of an upper portion, an intermediate portion and a lower portion, and three inlet flow paths are joined together and finally the multilayer material is extruded at one time. However, horizontal cavity molds require more modules to be assembled and are therefore bulky.

The vertical cavity mold of the present invention is composed of a plurality of modules arranged vertically, the plurality of modules being detachably connected to each other by fasteners, thereby constituting a mold body of the vertical cavity mold. Typically, multiple modules are bolted together as fasteners, but the fasteners are not limited thereto, and any fastener commonly used in the art can be used. The plurality of modules constituting the mold are preferably formed of a steel material, such as a national standard third degree steel material No. 17. However, it will be understood by those skilled in the art that the material forming the module is not limited to the steel material, but may be any suitable steel material for the mold.

The core feed port of the core flow channel is disposed in the center of one of the two outer modules, and the discharge port of the vertical cavity mold is disposed in the center of the other of the two outer modules. The outer feed port of the outer flow passage is disposed on at least one side in the lateral direction of the mold and is located between the two modules. The core flow path extends from the core feed opening to the discharge opening along the thickness direction of the mold. The outer flow path extends from the outer feed port perpendicular to the core flow path in the longitudinal direction of the mold between the two modules, and a flat portion is formed in the center of the mold to cover the core flow path to make the plurality of The outer sheet is coated with a core substrate. Further, the plating thickness of the core flow path and the outer flow path is in the range of 0.2 to 0.8 mm.
在制造多层复合板材时，每一个进料口处放置一个挤出机，从多个进料口将不同材料挤入模具中并最终从一个出料口共同挤出而形成多层复合板材。根据本发明，进料口从不同方向设置，从而方便布置多个挤出机，而不需要分配器即可实现多种原料的进入。因此，本发明的立式内腔模具可缩短 流道，减少流道阻力，增加流动性，从而减少由于流道不畅出现的焦料、放炮等现象，使产品性能、成型更有保障。此外，流道阻力的减少直接将设备设定压力减少70％以上，即工作压力设置从通常的30-40Mp减少到7-10Mp，从而减少生产过程中的事故发生率，进而保障安全生产。In the manufacture of multi-layer composite sheets, an extruder is placed at each feed port, and different materials are extruded from the plurality of feed ports into the mold and finally co-extruded from a discharge port to form a multilayer composite sheet. According to the present invention, the feed ports are disposed from different directions, thereby facilitating the arrangement of a plurality of extruders without the need for a dispenser to achieve entry of a plurality of materials. Therefore, the vertical cavity mold of the present invention can be shortened The flow channel reduces the flow path resistance and increases the fluidity, thereby reducing the phenomenon of coke and shots due to poor flow path, so that the product performance and molding are more guaranteed. In addition, the reduction of the flow path resistance directly reduces the set pressure of the equipment by more than 70%, that is, the working pressure setting is reduced from the usual 30-40Mp to 7-10Mp, thereby reducing the accident rate in the production process, thereby ensuring safe production.
