Description

CONTINUOUS WORK PIECE MOLD EQUIPMENT AND A MANUFACTURING METHOD THEREOF

The present invention relates to equipment for manufacturing a product and a method for manufacturing the product, and more particularly, to a continuous product casting equipment and a method for manufacturing the continuous product.

Traditional casting methods for glass articles use molds or sleeves combined with a pair of upper and lower mold cores to form a mold cavity. The method also utilizes the high temperature softening properties of the glass material to press and shape the glass material into the mold cavity through a high pressure pressurization process of the upper mold core and the lower mold core. This messes up the shape of the glass product and is close to the shape and thickness of the anticipated semi-molded product. The semi-molded product is then exposed to a suitable second high pressure sealing process during the cooling and shrinking process of the glass material as it increases the adhesion process. The surface shapes of the upper and lower mold cores are then transferred onto the glass material and the surface shapes necessary for the casting production of the glass article are finally finished.

To increase the production efficiency of the glass casting process, the glass industry often employs a single mold with multiple voids. The basic structure of a single mold used in multi-pore type glass casting equipment includes an upper substrate and a lower substrate. Each upper substrate is provided with a plurality of upper mold cores at the same time, and each lower substrate is equipped with a plurality of lower mold cores at the same time. The quantity and location of each bottom substrate coincides with the bottom mold core. Between the upper mold core, the lower mold core, and the upper substrate, the lower substrate has a gasket for adjusting the installation depth of the upper mold core and the lower mold core in the upper substrate and the lower substrate. This determines the thickness of the product to be cast by the void uniformity of each type. During the manufacturing process, the upper substrate and the lower substrate are guided to move in the vertical direction by the transfer device to manufacture the upper mold core and the lower mold core which are fixedly installed thereon, and operations such as mold closing, mold opening, and the like are performed. At the final stage, the casting of the glass product is finished.

The upper and lower mold cores of known casting equipment are formed separately and fixedly in the upper and lower substrates, respectively. If any one mold core is defective, part replacement can only be made if all the boards have been dismantled, which delays production. Alternatively, part replacement can be solved by cavity inserting. However, if the number of voids is increased, the production efficiency is lowered. In addition, each pair of mold cores adjusts the relative height by means of a gasket so that the thickness and size of the glass product cast by the respective mold gaps are uniform, so that high precision for unifying the height of each mold core is achieved. Accurate calculation and size control of all gaskets are required with the installation and adjustment of the figure. This results in cumbersome and lengthy processes such as mold assembly and mold repair processes that take a long time and a lot of energy. Therefore, the working time for mold assembly and mold repair of known casting equipment is long and the process is quite boring, which lowers the production efficiency.

Due to the above mentioned disadvantages, continuous product casting equipment needs to be provided. Each upper mold core in built-in form is individually installed and operated, not installed on the same upper substrate at the same time. In addition, each lower mold core is movably operated between the upper substrate cores. If any one mold core is defective, component replacement can be made without disassembling the entire board, and high precision installation and height adjustment of each mold core is not necessary to increase overall production efficiency.

And a single lower mold core movable on different work stations between the plurality of upper mold cores and performing different processing operations by the plurality of upper mold cores.

The two insulating pads are individually fixed on the upper pressure head and the lower pressure head. The upper mold core is fixed on the insulating pad of the upper pressure head and the infrared heating plate is fixed on the insulating pad of the lower pressure head.

The continuous product casting equipment further includes a cooling plate used to cool the molded article.

The upper mold core and the lower mold core each consist of curved cast faces to form a curved product.

It is an object of the present invention to provide a continuous product casting method.

Each upper mold core formed in the continuous product casting equipment described above is installed separately and operated simultaneously, but not on the same substrate. This helps to overcome the problems of long mold repair work and tedious casting processes in multi-void type casting equipment. In addition, the continuous product casting equipment does not use gaskets, eliminating the tedious gasket adjustment process. At the same time, the above-mentioned continuous casting equipment has upper and lower mold cores including a plurality of fixed upper mold cores and a movable lower mold core, on separate molds, and all upper portions fixed on different presentations. The mold core may be cast in engagement with each movable lower mold core to effect continuous molding of the product. If a mold core has certain problems, it can be replaced quickly without affecting the entire molding process. Thus, the mold maintenance work time of the above-mentioned continuous product casting equipment is shorter and the process is relatively simple. This overcomes the drawbacks of traditional product casting equipment by improving production efficiency. The continuous product casting method can continuously mold a plurality of products to increase production efficiency.
