Definitions
- the present invention relates to an injection molding method and apparatus, and more particularly, to an injection molding method and apparatus for molding a molding layer such as a sealing material on both surfaces of a plate-like body.
- a sealing material made of silicone rubber is formed on the outer peripheral portion.
- a sealing material for example, Japanese Patent Publication No. 11-09-746 (JP—A—11—3-0 9746) Production of silicone resin—metal composite The method is known. This conventional manufacturing method will be described with reference to FIG.
- a separator alone that is, a plate-shaped body
- the fixed mold 501 is inserted between the fixed mold 501 and the movable mold 502
- the fixed mold 501 is inserted.
- the movable mold 502 form a cavity 504.
- the cavity 504 is filled with a molten silicone resin as shown by the arrow.
- the front side V-metal material (that is, the molding layer) 506 is formed on the front side 505 of the separator unit 503, and the sealing material is flown on the back side 507 of the separator unit 503. Then, the back side sealing material 508 is formed.
- the front-side sealing material 506 and the back-side sealing material 508 constitute a sealing material 509 that covers the outer peripheral portion 503 a of the separator unit 503.
- the separator 510 is obtained by molding the sealing material 509 on the outer peripheral portion 503a of the separator unit 503.
- the fuel cell is assembled by sandwiching the electrolyte membrane, the negative electrode, and the positive electrode with the separator 510. Since hydrogen gas, oxygen gas and generated water flow in this fuel cell, it is necessary to form the separator seal well.
- the sealing material 509 is a thin silicone resin molded film, and when the molten silicone resin is injected into the cavity 504, the front side 505 of the separator unit 503 is sealed to the front side 505. Material 506 and the back of the separator 503 It takes time to pour the silicone resin of the molten state into the side 507 well. For this reason, it took a long time to manufacture the separator 510, which hindered the increase in the productivity of the fuel cell.
- the injection pressure of the silicone resin may be applied only to the front side 505 of the separator unit 503.
- the injection pressure of the silicone resin applied only to the front side 505 may be too large with respect to the rigidity of the separator 503. For this reason, it is necessary to suppress the injection pressure of the silicone resin so that an excessive injection pressure is not applied to the separator 503 alone.
- the present invention relates to an injection molding method for covering a plate-like body having a through-hole extending from a front surface to a back surface with an injection molding method on a first surface, wherein the gate and the plate-like body facing the through-hole are provided.
- a first mold having a front-side cavity surface facing the front surface, a receiving surface for storing the back surface of the plate-shaped body, and a second mold having a pin closing the through hole; and a back-cavity surface facing the back surface of the plate-shaped body.
- Open the hole and type 3 back cavities Forming a front-side cavity on the surface and the back surface of the plate-like body; and penetrating the front-side molding layer with an injection pressure for injecting the molding material through the gate, and filling the rear-side cavity with the molding material through the through hole.
- a step of forming a backside molding layer on the backside of the plate-like body is
- the molding material By penetrating the front molding layer by injection pressure, the molding material is efficiently guided into the rear cavity through the through hole. Therefore, it is possible to quickly fill the rear cavity with the molding material.
- the front side molding layer and the back side molding layer can be formed on the front and back surfaces of the plate-like body without taking much time, respectively, and the productivity can be improved.
- the first and second dies are clamped and the plate-like body is sandwiched to form a front-side cavity between the surface of the plate-like body and the first mold, and the front-side cavity is formed.
- a molding material such as resin into the inside
- forming a front side molding layer on the surface of the plate-like body replacing the second mold with the third mold, and sandwiching the plate between the third mold and the first mold
- Injection molding that forms a backside cavity between the backside of the plate and the third mold, and fills the backside cavity with a molding material such as resin to form a backside molding layer on the backside of the plate.
- An apparatus wherein the first mold is provided with a gate for injecting a molding material into the front side cavity and the back side cavity, and the gate faces a through hole formed in the plate-like body, and the second mold includes: A receiving surface is provided in contact with the back surface of the plate-like body, and In order to replace the second mold with the third mold, a pin that can be fitted into the second mold is provided at an opposing position where the second and third molds face the first mold and a retracted position where the second mold and the third mold are retracted from the first mold. A moving means for moving is provided.
- a pin is provided in the second mold, and the plate is sandwiched between the first and second molds so that the lipin is fitted into the through hole of the plate to close the through hole. Therefore, when the front side cavity is filled with a molding material such as a resin, the molding material is prevented from entering the through holes.
- a gate was provided in the first mold, and the gate was arranged so as to face the through hole. Therefore, by injecting the molding material from the gate by clamping the first and third molds, it penetrates the front molding layer with the generated injection pressure, and the resin is efficiently applied to the rear cavity through the through hole. It is possible to lead well.
- the molding material is quickly filled in the rear cavity, and the surface of the plate-shaped body and The molding layer can be formed on the back surface without spending much time, and productivity can be increased.
- the third mold is provided with a support protrusion for supporting the plate-like body by being brought into contact with the vicinity of the through hole.
- a support protrusion was provided on the third mold, and the support protrusion was brought into contact with the vicinity of the through-hole, thereby supporting the plate-like body near the through-hole. Therefore, even if the injection pressure acts on a portion of the plate-like body near the through hole, the portion is prevented from being deformed.
- the injection molding apparatus can be applied to an extremely thin plate-like body, and applications can be expanded.
