Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is an exemplary view showing a preferred embodiment of the present invention. In the present invention, a large number of metal molds are arranged on a plurality of bogies disposed on a conveyor that circulates through a booth box continuously, And also relates to a mold for a vehicle seat which can easily identify the time of production.

1, 2 and 3, the hinge 30 and the opening and closing means 40 for opening and closing the upper and lower dies 10 and 20, the upper and lower dies 10 and 20, A temperature measuring means 50 for measuring an internal temperature, and a viewing window 55.

The upper mold 10 is formed with an upper molding part 11 whose outer side is formed in the form of a car seat in an embossed state and the lower mold 20 is provided with a lower mold 20 for accommodating the outside of the upper molding part 11, And a groove 22 is formed in the lower molding part.

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 opening and closing means 40 includes a cylinder 41 which is operated by hydraulic pressure or pneumatic pressure and which is installed vertically to the side of the upper and lower molds and is connected to the lower mold 20 from the lower side of the cylinder 41 And an operating rod 45 which is connected to the upper mold 10 at the end of the cylinder 41 rod.

The upper mold 10 is provided with a charging port (not shown) through which the foaming liquid of the vehicle seat is inserted so that the upper mold 10 closes the lower mold 20 so that the upper and lower molding portions 11, So that the foamed liquid of the vehicle seat can be injected through the injection port in a state in which the vehicle seat-shaped cavity is formed through the upper and lower molding portions 11,

A temperature measuring means 50 for measuring the internal temperature of the upper and lower dies 10 and 20 is provided in the recess 22 formed in the lower mold 20. [

And a viewing window 55 which is seated on the upper side of the groove 22 so as to be equally positioned on the horizontal line with the surface of the lower forming part 21 and allows the operator to observe the temperature measuring means 50 provided inside the groove 22 ).

Therefore, by detecting the internal temperature of the upper and lower molds 10 and 20 in which the vehicle seat is formed due to the temperature measuring means 50 provided in the groove 22, the optimum temperature The molding operation can be performed through the upper and lower molds 10 and 20 when the temperature is maintained, so that it is possible to produce a high-quality product while minimizing the generation of defective products at the initial stage.

Here, the transparent window 55 is preferably made of a heat-resistant tempered glass so as not to cause damage to the inside of the upper and lower molds 10 and 20 having a high temperature.

The temperature measuring means 50 includes a coloring layer 51 having a color different from the original color due to the heat conduction due to the temperature rise of the inner surface of the groove 22 by mixing the pigment with the color changing with the temperature change, .

The color change layer 51 is used for the purpose of temperature measurement by using a compound which is clearly discolored at a specific temperature or a compound which is melted and changes its state as a pigment.

That is, the pigment used in the color discoloration layer 51 has a wide range of color change points and is used for the purpose of temperature measurement due to heat conduction due to the temperature rise of the upper and lower dies 10 and 20, The discolored pigment is reversibly pigmented by cooling back to its original color.

The pigment used for the color discoloration layer 51 is a color conversion method that uses the transparency of the pigment when the temperature is changed. For example, in the case of three colors, the first stage surface is coated in black, the second stage is yellow, . When the temperature rises, the black color becomes transparent and the second color appears. When the temperature rises, the second yellow color becomes transparent and the third red color is seen. When the temperature cools, the opposite effect appears.

The temperature measuring means 50 includes a temperature sensor 52 for sensing a set temperature by increasing the temperature of the inner surface of the groove 22 and a temperature sensor 52 for detecting a temperature sensed by the temperature sensor 52 And a lamp control unit 53 for driving the lamp 54 to drive the lamp 54.

That is, a temperature range in which the molding operation can be performed in advance is set in the temperature sensor 52, and when the temperature is raised for the molding operation of the upper and lower dies 10 and 20, The temperature sensor senses the temperature rise and the lamp control unit 53 drives the lamp 54 so that the operator can identify the temperature.

5, the cylinder 41 of the opening / closing means 40 is actuated by the control means 70, and the control means 70 is controlled by the temperature sensor 52, And to open the upper mold 10 in the lower mold 20 when the temperature is sensed at the set temperature.

When the upper mold 10 is opened in the lower mold 20, the operator performs the application of the mold release agent and the insert operation of the subsidiary material for molding the vehicle seat without further confirmation.

4, the identification groove 23 is formed on the surface of the lower molding part 21 of the lower mold 20, and is formed of alphanumeric characters so as to identify the production date and time, The identification member 60 is grounded and fixed to the groove 23 to form alphanumeric characters in the pad body foamed in the upper mold 10 and the lower mold 20. [

The identification body 60 can identify the date of manufacture of the vehicle seat by forming alphanumeric characters in the pad body foamed in the upper mold 10 and the lower mold 20 to facilitate inventory management and productivity It is possible to have an effect that can be achieved.

The detailed form of the identification body 60 is composed of a main body 61 which is entirely seated in the identification groove 23 and an identification part 63 in which English alphanumeric characters are protruded in a positive shape on the upper side of the main body 61 Loses.
