- the present invention relates to a method for producing a skin-integrated laminate and a mold apparatus used therefor.
- the present invention relates to a method for manufacturing a skin-integrated laminate for manufacturing a skin-integrated laminate in which a skin is accurately layered and integrated from one surface of a synthetic resin molded core material to a wood end surface, and a mold apparatus used therefor. About.
- a skin-integrated laminate in which a skin material is layered and integrated on one surface of a synthetic resin molded core material is widely used.
- a complex shape having a folded part around the periphery of the synthetic resin molded core material.
- a method is used in which the skin material is pushed into the wood end face and rolled up using a split type that slides horizontally to the wood end face. ing.
- the terminal material is forcibly extended from the skin material in a state where the terminal material is clamped by the clamp mechanism, so that the synthetic resin molded core material is made of wood. Because it is integrated with the end face, the skin material after molding is There has been a problem in that the skin material shrinks due to residual stress and heat shrinkage due to the heat resistance test, and the inner synthetic resin molded core layer is exposed, resulting in poor appearance. In addition, a special split mold must be used, which complicates the molding process and also complicates the equipment itself.
- the present invention solves the above-mentioned conventional problems, and the skin material is tightly rolled up to the wood end surface of the synthetic resin molded core at the same time as the molding of the synthetic resin molded core, and is layered and integrated. In addition, even after molding, the skin material does not shrink and has an excellent appearance, so that a high-quality skin-integrated laminate can be efficiently produced, and the apparatus itself is extremely simple. It has been completed for the purpose of providing a method for manufacturing a one-layer skin layered body having a structure that can be easily maintained and inspected, and a mold apparatus used therefor.
- FIG. 1 is a longitudinal sectional front view showing an embodiment of a mold apparatus according to the present invention.
- FIG. 2 is a process explanatory view of an embodiment of the method of the present invention, showing a process of setting a skin material.
- FIG. 3 is a process explanatory view of an embodiment of the method of the present invention showing a process of supplying a molten resin material for a core material.
- FIG. 4 is a process explanatory diagram of an example of the method of the present invention, showing a process of clamping a male mold and a female mold.
- FIG. 5 is a process explanatory view of the embodiment of the present invention showing a process of removing a molded product.
- FIG. 6 is a cross-sectional view of a skin-integrated laminate manufactured by the method of the present invention.
- the present invention made in order to solve the above-mentioned problem is to provide a skin material in which a terminal is clamped with a clamp mechanism between a pair of male and female dies. At the same time, between the skin material and the male mold, a molten resin material for forming a molded core material integrated with the skin material is co-supplied and clamped by one mold to form a skin on the surface of the synthetic resin molded core material.
- the peripheral end of the cavity formed between the male mold and the female mold is an end part in a mold-clamped state.
- a plate type is provided around the end opening, into which the tip for forming a wood end can enter, so as to be able to advance and retreat, and the tip for forming a wood end is closed when the male mold and the female mold are closed.
- the end opening is closed by a plate type projecting into the cavity from the end opening, and the clamp of the skin material by the clamp mechanism is used when supplying the molten resin material.
- a part of the skin material is extended to the back side of the tip for forming the wood end in the cavity by extending the molten resin material, and a synthetic resin molded core material is formed in the cavity.
- the first invention is a method for manufacturing a skin-integrated laminated body, which is characterized in that a skin material is rolled from one side to the end of a tree and laminated and integrated.
- a male mold 2 for use, and a cavity 1 1 having an inner peripheral end facing the male mold so as to be freely separated from the male mold and having an end opening 10.
- a mold used for the structure of an integrated skin laminate comprising an openable and closable clamp mechanism for gripping and fixing a terminal of a skin material interposed between the male mold and the female mold provided at a lower peripheral edge of the male mold.
- the device is the second invention.
- Reference numerals 1 and 2 denote a pair of female and male molds constituting a laminate molding cavity, and the female mold 1 is a base.
- a cavity 11 is formed above the male mold 2 fixed on the metal mold 2 with the peripheral end opened as an end opening 10 between the male mold 2 and the male mold 2 in a clamped state. They are arranged so as to be able to freely contact and separate from each other.
- Reference numeral 3 denotes a clamp mechanism disposed on the lower peripheral edge of the male mold 2, and the clamp mechanism 3 is a terminal of the skin material 21 interposed between the male mold 2 and the female mold 1. It can be opened and closed so that it can be clamped.
- Numeral 4 is a plate type which is rotatably attached to the outer periphery of the lower end of the female die 1 and has an upwardly directed tip portion 5 for forming a wooden end face which can enter the end opening 10. ing.
- the clamp mechanism 3 clamps the skin material 21 by a pair of gripping claws operated by an air cylinder. Any mechanism, such as one that grips by vacuum suction by a measure, can be used, and a loose clamp type that loosens the holding force when a certain or more tensile force is applied to the skin material 21
- the plate type 4 is pivotally attached to the lower end of the outer periphery of the female type 1, and the plate type 4 is connected to the air cylinder 6 and hinged. It is configured to freely rotate around the center 7 and take two states, a state in which the cavity 11 is closed and a state in which it is opened.
- a soft sheet layer 21a such as a vinyl chloride sheet shown in Fig. 6 is placed between the male mold 2 and the female mold 1 as shown in Fig. 6.
- Polypropylene A skin material 21 composed of a olefin-based pad layer 2 1b such as foam, polyethylene foam, etc. is disposed, and its terminal portion is clamped to the clamp mechanism 3.
- the plate type 4 is held in a horizontal state, that is, in a closed state by the operation of the air cylinder 6.
- the molten resin material 2 for molding the core material is supplied from a material supply hole (not shown) provided in the male mold 2.
- a material supply hole not shown
- the molten resin material 2 2a supplied and pressurized to the skin material 21 in the cavity 11 is replaced by the plate type 4 located in the cavity 11. It is extended to the back side of the tip 5 for forming the wood end surface, and is made of synthetic resin in the cavity 11 1.
- the core material 2 2 is formed, and at the same time, the skin material 21 from one side to the wood end surface In this process, the skin material 21 is separated from the conventional one by releasing the clamp of the terminal. Instead of being entangled with the wood end face in a stretched state, it is entangled with the wood end face in a natural state where no tensile force acts and is integrated with the synthetic resin molded core material 22. Becomes In addition, since the tip of the plate mold 4 is formed at the tip 5 for forming the wood end face, the skin material 21 is surely extended to the back side along the wood end face of the synthetic resin molded core 22.
- the female mold 1 is raised to open the mold, and the plate mold 4 is rotated to actuate the male mold 8 of the male mold 2 as shown in FIG. And trimming the surplus part following the wood end face, and the skin material 21 as shown in Fig. 6 is rolled up from one side of the synthetic resin molded core material 22 to the wood end face.
- the layered skin-integrated body 20 is obtained.
- the skin-integrated laminate 20 obtained in this manner is layered and integrated so that the skin material 21 completely covers the tree end surface from one surface of the synthetic resin molded core material 22. Moreover, since the skin material 21 is in a natural state in which no tensile force acts, the skin material 21 is formed after molding due to the residual stress or due to the heat shrinkage caused by the heat test. The phenomenon that the material 21 shrinks to expose a part of the synthetic resin molded core material 22 is surely prevented.
- the skin material is layered and integrated with the synthetic resin-molded core material being formed while being entangled from one side to the tree end simultaneously with the molding of the synthetic resin-molded core material.
- the skin material does not shrink even after molding and has an excellent appearance, and a high-quality skin integrated laminate can be efficiently produced. It can be produced well.
- the peripheral end of the cavity formed by the male mold and the female mold is opened as an end opening, and the female mold is formed.
- the structure is extremely simple, maintenance and inspection cannot be performed easily at a low cost.
- the present invention is extremely significant in that it solves the problems of the conventional method for producing a skin-integrated laminate and the mold apparatus used therefor and contributes to the development of industry.
