Description

Lightweight mobile toilet panel manufacturing method

The present invention relates to a "panel manufacturing method for lightweight mobile toilets", and more particularly to a method for manufacturing a mobile toilet panel that can greatly increase productivity and achieve light weight requirements.

According to the conventional fluid toilet panel, the blow molding method is mostly performed by blow molding, and the plastic material is mainly melted by a hollow molding machine, and then placed in a molding die. The molding die has an upper die and a lower die, and the inside The mold cavity is provided, and the mold clamping portion of the upper and lower molds has a blow hole extending to the cavity position, so that the hollow molding machine can penetrate the cavity through the blow hole through a blow pipe, and then generate the plastic material placed in the cavity. In the case of blow molding, the hollow molding opportunity blows the plastic material from the blowing pipe, so that the plastic material can be gradually expanded and formed, and finally becomes the shape of the cavity. When the molding die is opened, an inner hollow shell can be obtained. The panel is mounted on the top and outer sides of the mobile toilet with the panel.

However, the conventional structure as described above still has the following problems in practical applications: (1) one blow molding can only produce one toilet panel, and the slow mode cannot improve productivity, production and raw materials. The cost is also higher; (b) the blown-out toilet panel is a hollow shell-like body that is closed on each side, so that the conventional toilet panel has a large weight, and when the heavy-weight panel is installed in the mobile toilet When it is installed, it will not be possible to make the mobile toilets lighter, which is relatively difficult to handle and install.

Therefore, the present inventors have invented the present invention in view of the fact that the idea of creation and creation has been designed with many years of experience, and has been explored and tested by various parties, and has been repeatedly modified and improved.

The method for manufacturing the panel of the lightweight mobile toilet of the present invention is completed by the procedures of blow molding and cutting, and can complete the production of the lightweight mobile toilet panel, wherein the blow molding is to melt the plastic material by the hollow molding machine. And then placed in a molding die, the molding die has an upper die and a lower die, and a mold cavity is arranged inside, and the mold clamping portion of the upper and lower molds has a blow hole extending to the cavity position, so that the hollow molding machine can blow The trachea penetrates into the cavity through the blow hole, and then is connected with the plastic material placed in the cavity. During the blow molding, the hollow molding opportunity blows the plastic material from the blow pipe, so that the plastic material can be gradually expanded and formed. As the shape of the cavity, when the molding die is opened, an inner hollow shell-like body can be obtained, and the shell-like body has a frame-shaped base, and the base portion is connected by a joint edge A top surface and a bottom surface are connected, and the design of the molding die is adopted to enable the shell body to have a thin thickness at the joint edge, so that the shell body can be easily cut at the joint edge, and the top surface and the bottom surface are Each side is formed with a hook portion, and the cutting is to cut the top surface and the bottom surface of the shell body from the joint edge, so that the top surface and the bottom surface can each become a panel for flowing the toilet, and because the joint edge of the shell body has been The thinning process is carried out by the design of the forming mold, so that the cutting process can be more time-saving, labor-saving and convenient, and the formation of the hook portion enables the panel to be smoothly installed on the mobile toilet; thereby, the weight can be constructed. The method of the panel process of the mobile toilet.

(1) The panel manufacturing method of the lightweight mobile toilet of the present invention, which utilizes the cooperation of the blow molding and the cutting two processes, can produce two panels of mobile toilets at one time, and the system can effectively increase the productivity and enable the mobile toilets to be dosed. Production, the required production and raw material costs are also lower.

(2) The panel manufacturing method of the lightweight mobile toilet of the present invention, which cuts the blown shell into two panels, thereby greatly reducing the weight of the single panel, and allowing the mobile toilet combined by the panel to To achieve the requirement of weight reduction, it is relatively easy to carry and install.

(3) The panel manufacturing method of the lightweight mobile toilet of the present invention, the joint edge is thinned by the design of the molding die, so that the panel can be more easily cut from the joint edge, thereby saving time and labor. Processing advantage.
