Processing Method and Process of Huai 'an Thick Sheet Blister Molding
Time: 2021-10-12
The invention relates to a thick plate processing method, in particular to a Huai'an thick sheet blister processing method. Huaian thick sheet plastic forming is a thick plate processing technology. The thick plate is attached to the mold by negative pressure adsorption. The thick plate becomes soft under heating, and the thick plate is closely attached to the mold to form.
In the existing processing method of Huaian thick sheet blister molding, heating and compression adsorption molding are carried out separately. First, the thick sheet is heated and melted, and then the hot-melt thick sheet is attached to the mold, and adsorption molding is carried out under negative pressure. This processing method needs to be carried out step by step, and the processing efficiency is low.
Therefore, the purpose of the present invention is to provide a processing method for forming Huaian thick sheet absorbent plastic, which has the advantages that hot melt and negative pressure adsorption can be performed at the same time, and the processing efficiency is high. On the one hand, the present invention provides a processing method for Huai'an thick sheet suction plastic molding, including the following steps: placing the thick plate on the mold; heating the thick plate above the thick plate; evacuating the mold and stopping the heating to make the thick plate adhere to On the mold; blow down from above the thick plate to quickly form the thick plate.
The Huai'an thick sheet plastic forming processing method of the present invention vacuums the mold while heating the thick plate or after heating the thick plate, so in the process of negative pressure forming of the thick plate, the heating can be stopped or not, and can be carried out simultaneously. Thus, the operation steps in the heating and negative pressure adsorption process are simplified, thereby improving the processing efficiency. In addition, Huaian thick sheet blister by blowing air on the thick sheet, the thick sheet can achieve the effect of rapid cooling and accelerate the forming of the thick sheet. In combination with the above operations, the effects of accelerating the thick plate forming and improving the efficiency are achieved together.
Huaian thick sheet blister When air is blown down from above the thick plate, the method further includes the step of spraying and cooling the thick plate obliquely from above the thick plate. Through Huaian thick sheet blister spraying and cooling, the accelerated cooling of the thick plate can be realized. Spraying from the top of the thick plate obliquely downward can make the spraying and heating devices staggered without affecting each other. And spraying and cooling the slab includes forming a spray by the atomizer and spraying the spray on the upper surface of the slab. The droplets formed by atomizer spray are small, which is conducive to the evaporation of water droplets. Huaian thick sheet blister heating the thick plate above the thick plate includes the following steps: setting a heating plate and a lifting mechanism, the heating plate is provided with a heating wire, the heating plate is set at the bottom of the lifting mechanism, and the lifting mechanism drives the heating plate to lift; The heating plate is set above the mold; the heating plate is placed above the thick plate, and the thick plate is heated according to the preset heating temperature and heating time.
Huaian thick sheet blister lifting mechanism drives the heating plate to rise and fall. When heating is needed, the heating plate can be lowered, or it can stay at a given position to maintain an appropriate distance from the thick plate. During the entire heating and stopping process, the position of the heating plate can be kept unchanged, thereby simplifying the operation steps. Placing the heating plate over the thick plate includes placing the heating plate over the thick plate and adhering to an upper surface of the thick plate. The heating plate is attached to the thick plate for heating, which can accelerate the heating effect. At the same time, the heating plate is attached to the thick plate, and the edge of the heating plate is attached to the thick plate, which plays a sealing role when absorbing the thick plate under negative pressure and promotes the forming of the thick plate. At the same time or after the negative pressure adsorption is completed, the heating of the heating plate is stopped.
Huaian thick sheet blister vacuuming the mold includes the following steps: attaching the lower surface of the thick plate to the edge of the mold, communicating the bottom of the mold with a vacuum generating device, starting the vacuum generating device, and vacuuming the cavity of the mold according to a preset vacuum degree, so that the thick plate is attached to the mold. The thick sheet is attached to the mold, and when absorbed by the negative pressure, it is easier to form the thick sheet.
According to the processing method of thick plate blister molding of the present invention, the two sides of the thick plate are lapped on the corresponding chain and transported by the chain; when transported to the limit plate, both sides of the thick plate are limited by the limit plate, and the position is fixed. Above the mold. The mold of the present invention can be a single mode. After the thick plate is placed on the mold, the upper surface of the thick plate is heated and hot-melted, and the lower surface of the thick plate is adsorbed on the mold in a negative pressure state, thereby forming, and the formed thick plate Stop heating and quickly cool down under the dual action of blower and atomized spray.
Huaian thick sheet blister cooling after the thick plate in the chain transport continues to move forward until sent out. The invention simplifies the operation steps at the time of heating and negative pressure adsorption, and improves the processing efficiency; in addition, accelerates the forming of the thick plate, and achieves the effects of accelerating the forming of the thick plate and improving the efficiency.
