Abstract
Description
- 1. Field of the Invention
- The present invention relates to the technical field of a compressed air molding equipment, and more particularly to the equipment applied in an ejecting mechanism of a cutting device for ejecting and latching a cut end product in a knife mold and moving the end product accordingly to facilitate an automated manufacturing process.
- 2. Description of the Related Art
- In general, plastic cups for containing beverage or food packaging containers for a protection purpose are manufactured by compressing a blank such as a PVC film or PE film into various different shapes and forms by vacuum pressure or atmospheric pressure through vacuum molding equipments or compressed air molding equipment.
- To improve the molding quality and efficiency of a fully automated production by using the compressed air molding equipment, through holes are formed in rows on both sides of the blank respectively for driving the blank to move in the compressed air molding equipment during manufacturing processes such as forming, cutting and receiving processes. In the cutting process, notches are formed on a blade portion of a knife mold to facilitate the process of receiving the material by a stack method, so that when the knife mold is aligned with a cutting mold to perform the cutting process, contacts are formed between the end product and the blank, so as to continuously feed materials. In the process of receiving materials, at least one ejector rod pushes the end product, so that the end products can be stacked with one another by the effect of gravitational force after the contacts are broken.
- However, the contacts have a very small width, and thus some of the contacts have been broken already in the step of dragging the blank, and a tilted angle between the end product and the blank is resulted. When the ejector rod is stretched out, and the end product cannot be pushed or ejected completely, it is necessary to remove the end product manually, so that the automated production is delayed, and the production efficiency is affected. Since the contacts are ejected or broken by the ejector rod, bumps are formed at the periphery of the end product and cannot be eliminated completely. Therefore, the end product has a poor look, and may cut or injure users easily. Obviously, the aforementioned drawbacks must be overcome and improved.
- In view of the aforementioned drawbacks of the prior art, it is a primary objective of the present invention to overcome the drawbacks by providing an ejecting mechanism of a cutting device, such that when the cutting process takes place, an end product is pushed and latched to a knife mold, and the end product can be moved with the knife mold to a material receiving position, and finally an ejector rod installed in the knife mold is used to eject the end product to achieve the stacking effect and the fully automated production effect. In addition, no bumps are formed at the periphery of the end product when the aforementioned method is adopted, so that the invention can improve the production efficiency and quality significantly.
- To achieve the aforementioned objective, the present invention provides an ejecting mechanism of a cutting device, wherein the cutting device includes a power module, a knife mold and a cutting mold, and the power module is coupled to the knife mold, and the knife mold has a plurality of blade portions, and the cutting mold is corresponsive to the blade portions and includes at least one mold cavity, and the power module drives the knife mold to engage with the cutting mold for cutting an end product and a connecting portion of a blank, and the ejecting mechanism comprises: a base, fixed onto the bottom of the mold cavity; a moving plate, installed on the base and having an interval apart from a side of the base, and the top of the moving plate being corresponsive to the end product and having at least one supporting portion; a plurality of guide columns, installed between the base and the moving plate, for guiding the direction of the moving plate moving vertically with respect to the base; and a plurality of elastic elements, installed between the base and the moving plate; such that after the knife mold and the cutting mold are engaged and the connecting portion is cut, the moving plate is ejected by the resilience of the elastic elements, and the supporting portion is provided for latching the end product into the knife mold, so that the end product can move with the knife mold.
- In a preferred embodiment of the present invention, the supporting portion is substantially an L-shaped structure, viewing from a cross-sectional side. To cope with the cutting requirements, the quantity, the installation position, and the shape of the supporting portion may vary as follows: (1) The supporting portion is corresponsive to the mold cavity and the plurality supporting portions are installed on at least one pair of edges of the moving plate; (2) The supporting portion is corresponsive to the mold cavity and the plurality supporting portions are installed at four corners of the moving plate; (3) The supporting portion is corresponsive to the mold cavity and the plurality supporting portions are installed on at least one pair of symmetric edges and four corners; and (4) The supporting portion is corresponsive to the mold cavity and has a fence structure surrounding the periphery of the moving plate.
- It is noteworthy that the base, the moving plate and the supporting portion have a total height greater than or equal to the depth of the mold cavity, so that the resilience of the elastic element can be used to eject the end product into the knife mold.
