Problems solved by technology

[0008] In this solution, because the amount of foaming gas left on the side of the mold cavity cannot be controlled, when it is small, the foaming material will enter the annular space and form a ring thicker than that of the burr produced when there is no seal. For thicker burrs, it will take a lot of time and effort to remove the burrs

Embodiment Construction

[0044] exist figure 1 The arrows mark the extension direction L, width direction W and thickness direction H of the seal A of the present application. In this application, the extension direction L of the seal A refers to the longitudinal direction of the seal, which is the same as its width The direction W and the thickness direction H are perpendicular to each other.

[0045] The sealing member of the present invention can be applied to a foam molding mold for forming foam moldings such as car seat sponges, and is used to be installed on the parting surface of one of the upper and lower molds, and the molds are aligned after the molds are closed. cavity is sealed. In this embodiment, a foam molding die applied to foam moldings such as car seat sponges is exemplified, but the sealing material of the present invention can also be applied to sealing between opposing surfaces of two members of other types.

[0046] First, the sealing material A of this embodiment will be desc...

Abstract

The invention relates to a sealing part, a foamed forming mould and a foamed forming method. The sealing part comprises a sealing portion and an installing portion; the sealing portion is shaped like a plate and comprises a first sealing surface and a second sealing surface which are opposite to each other in the thickness direction of the sealing part; the installing portion is used for installing the sealing part on a using object; a fluid storing groove and a fluid guiding groove are formed in the first sealing surface, the fluid storing groove extends in the extending direction of the sealing part, the fluid guiding groove is formed in the sealing surface on one side in the width direction and penetrates from the end face of one side in the width direction of the sealing part to the fluid storing groove, and in a sealing state, fluid located on the end face of one side in the width direction can enter the fluid storing groove through the fluid guiding groove.

Description

technical field [0001] The present invention relates to a sealing material, a foam molding die, and a method for manufacturing a foam molding. Background technique [0002] A mold for foam molding used for producing a foam molded article such as car seat sponge generally includes an upper mold and a lower mold. When performing foam molding, the upper mold and the lower mold are opened, and the foam molding material is injected into the mold cavity of the lower mold, and then the upper mold and the lower mold are closed, and the foaming reaction occurs through the foam molding material. A molded foam body that fills the cavity is formed inside the cavity of the mold for foam molding. In the process of foam molding, with the foaming reaction, the volume of the foam molding material gradually expands, and the air that originally existed in the mold cavity is discharged from the vent hole on the upper mold to the center of the foam molding mold. outside. [0003] Due to the l...
