Abstract

The present invention relates to an automobile seat mold for producing a breathable seat, and more specifically, to an automobile seat mold comprising: an upper mold for forming an upper mold unit which has an outer side raised in the shape of an automobile seat; a lower mold for forming a lower mold unit which is recessed in the shape of an automobile seat so as to accommodate the outer side of the upper mold unit; a hinge which is installed behind the upper mold and the lower mold to open or close the upper mold; an opening/closing means which opens or closes the upper mold; an injection opening through which a foaming liquid for a pad body is injected; a first protruded portion of a metallic material whose one side is inserted in a first insertion groove formed on the upper mold unit and which protrudes downwardly; a second protruded portion of a metallic material whose one side is inserted in a first insertion groove formed on the lower mold unit and which linearly aligns with the first protruded portion when the upper and lower mold units are coupled with each other; and a magnetic body which is formed between the first and second protruded portions and the first and second insertion grooves. Accordingly, due to the first protruded portion and the second protruded portion which are coupled with each other inside the upper and lower mold units, when the foaming liquid for a pad body is compressed and solidified in the upper and lower mold units, production of the automobile seat is completed with a breathing hole formed therein. Consequently, the need for a process for forming the breathing hole is eliminated and the breathable automobile seat can be produced in a single molding operation, thus significantly improving workability.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mold for a vehicle air-

The present invention relates to a mold for manufacturing a ventilation sheet for a vehicle, and more particularly, to a mold for manufacturing a ventilation sheet for a vehicle, which comprises first and second projections mutually intermingled with upper and lower molds for machining a vehicle seat, To a mold of a ventilation sheet for a vehicle.

Recently, as the quality of life has improved, the use of vehicles has been rapidly increasing for travel and other hobbies, except for exiting and leaving the home. As a result, Seat comfort, comfort, and comfort during seat occupancy are important.

Such a vehicle seat is largely constituted by a rigid frame and a seat cover which support external impact. More specifically, a rigid frame is formed by molding a synthetic resin liquid such as urethane into a mold, And a shock absorbing foam pad is provided as necessary.

In order to manufacture the rigid frame, a plurality of dies including upper and lower dies are arranged on a plurality of bogies disposed on a conveyor that continuously circulates through the booth box, and when the upper and lower dies are circulated, Later, when the foamed liquid is formed in the form of a rigid frame in the upper and lower molds, the product is completed from the upper and lower molds.

This foamed liquid is injected, the rigid frame is taken out, and the return to the original state is performed by the same operation at a predetermined point.

Therefore, it is common that the vehicle seat is produced through the above-described process. Since the vehicle seat is not ventilated well, the driver feels a sense of discomfort due to a lot of sweat between the buttocks and the seat of the driver during summer operation. So that a vehicle seat in which ventilation is performed has been actively developed.

In the present invention, a mold made up of upper and lower molds is formed so as to form a vehicle seat on a plurality of bogies provided on a conveyor continuously circulating through a booth box And more particularly, to a metal mold for a vehicle air-permeable sheet in which molding work of a vehicle seat is performed by opening and closing a plurality of upper and lower dies.

The present invention is characterized in that the hinge 30 and the opening and closing means 40 for opening and closing the upper and lower dies 10 and 20 and the upper and lower dies 10 and 20 and the upper and lower dies 10 and 20 First and second protrusions 50 and 60 and a magnetic body m for forming a ventilation port of the vehicle seat.

The upper mold 10 is formed in the form of a car seat on the outside with an embossed shape and an upper molding portion 11 having a plurality of first drawing grooves 12 is formed so that the first projection 50, do.

The lower mold 20 is formed in the form of a car seat at an engraved position so as to accommodate the outer side of the upper forming part 11. A plurality of second inlet grooves 22 are formed in the lower mold 20 so that the second projecting part 60, The lower molding portion 21 is formed.

The opening and closing means 40 for opening and closing the upper mold 10 together with the hinge 30 provided on the rear side of the upper mold 10 and the lower mold 20 for opening and closing the upper mold 10, .

The upper mold 10 is divided into upper and lower molds 10 and 20 so that the upper mold 10 is opened and closed by the hinge 30 and the opening and closing means 40 from the lower mold 20.

The upper mold 10 is provided with a charging port for introducing the foaming liquid so that the upper mold 10 closes the lower mold 20 so that the upper and lower forming parts 11 and 21 are mutually assembled, So that the foamed liquid can be injected through the injection port in a state in which the vehicle seat-shaped cavity is formed through the lower molding portions 11,

As shown in FIGS. 2 and 3, the first protrusion 50 is formed of a metal material having one side drawn into the first inlet groove 12 formed in the upper forming part 11 and projecting downward.

The second protrusion 60 is inserted into the first protrusion groove 22 formed in the lower molding part 21 so that when the upper and lower molding parts 11 and 21 are mutually combined, ), Which is grounded in a straight line.

The magnetic body m is formed between the first and second protrusions 50 and 60 and the first and second inlet grooves 12 and 22 so that the first and second protrusions 50 and 60 are inserted into the first and second inlet grooves 12 and 22, The first and second protrusions 50 and 60 are selectively inserted into the first and second inlet grooves 12 and 22 which are formed in a large number while the first and second protrusions 50 and 60 can be fixed by the first and second protrusions 12 and 22, So that it is possible to form an image.

At this time, a separate sealing means is drawn into the first and second lead-in grooves 12, 22, into which the first and second protrusions 50, 60 of the first and second lead-in grooves 12, .

When the sheet foam is molded due to the upper and lower forming portions 11 and 21, the first and second protrusions 50 and 60 mutually combined form the foamed liquid The ventilation holes are formed to complete the vehicle seat and the work for forming the ventilation holes is eliminated, and the ventilation sheet for the vehicle is machined by a single mold operation, so that the workability is remarkably improved.

Here, the first and second protrusions 50 and 60 may be formed in various shapes, and the first shape may be any one of the first and second protrusions 50 and 60 as shown in FIGS. 4 (a) and 4 (b) One of which is formed in a hollow form, and the other is formed so as to be inserted into a hollow portion so as to be mutually formed.

The second type of the first and second protrusions 50 and 60 includes a plurality of protrusions 51 formed at the tip of the first protrusions 50 as shown in FIGS. 5A and 5B, A plurality of receiving portions 61 are formed at the tips of the two projections 60 to receive the pawl bodies 51 therein.

The third form of the first and second protrusions 50 and 60 includes a first protrusion 50 and a second protrusion 60 which are engaged with a grounded portion of the first protrusion 50 and the second protrusion 60, And two-phase coalesced bodies 53 and 63, respectively.

Accordingly, various forms of the first and second protrusions 50 and 60 can be formed by smoothly shaping the shapes of the vent holes formed by the first and second protrusions 50 and 60 and the first and second protrusions 50 and 60 In order to prevent damage.

On the other hand, as shown in Fig. 1, the opening and closing means 40 includes a cylinder 41, which is operated by hydraulic pressure or pneumatic pressure, is installed vertically to the side of the upper and lower dies, And an operating rod 45 connected to the upper mold 10 at the end of the cylinder 41 rod.
