Description

[0001] Thermo couple sensor for mold [0002]

The present invention relates to a thermocouple sensor for a mold, and more particularly, to a thermocouple sensor for a mold which can be easily assembled and used, has improved durability, and is easy to install in a mold.

Generally, a thermocouple sensor is made by connecting two ends of two kinds of metal wires. When a temperature difference occurs at the contact points of both ends, a thermoelectric power is generated in the closed circuit and a current flows in the circuit. Is determined by the combination of the temperatures at both ends and the two metal wires, and thus, the thermoelectric power according to the temperature of the specific thermocouple can be read in advance, thereby making it possible to measure the temperature.

In order to measure the temperature inside the mold, a hole is formed in the inside of the mold and the thermocouple sensor is installed to measure the temperature inside the mold.

The conventional thermocouple sensor for a mold is constituted by a number of parts and has poor assemblability and durability when used for a long time.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of a normal-force sensor for a mold according to the present invention,
FIG. 2 is an exploded perspective view of FIG. 1,
Fig. 3 is a sectional view of Fig. 1. Fig.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a conventional soft magnetic sensor for a mold according to the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a sectional view of FIG.

Referring to these drawings, the thermocouple sensor 100 for a mold according to the present invention includes a sensor housing 110, a sensor rod 120 coupled to one side of the sensor housing 110, A spring 130 and a sensor cable 140 having one end disposed inside the sensor housing 110 and coupled to the sensor rod 120.

First, the sensor housing 110 is formed in a pipe shape with a space formed therein. One end portion of the sensor housing 110 is provided with a first opening 111 having a small hole shape for exposing the sensor rod 120, And the sensor cable 140 are inserted into the second opening 112. The second opening 112 is formed in the second opening 112,

The second opening 112 is formed to be larger than the first opening 111 so that the one end of the multi-step spring, the sensor rod 120, and the sensor cable (not shown) 140 can be assembled in and out.

A first threaded portion 113 is formed in an inner part of the second opening 112.

A second threaded portion 114 is formed on an outer circumferential surface of one end of the sensor housing 110 and a nut ring 115 having a third threaded portion 115a is coupled to the second threaded portion 114. Thus, the third threaded portion 115a can provide a larger diameter than the second threaded portion 114 and can be used interchangeably with the two sizes of holes that can be formed in the mold.

A hexagonal staple portion 116 is formed at one end of the sensor housing 110 to grip the hexagonal staple portion 116 using a tool such as a stanchion when the sensor housing 110 is coupled to the mold, (110) can be easily installed on the mold.

The first opening 111 is formed to expose the sensor rod 120. The sensor rod 120 is exposed in the mold to measure the temperature at a specific point.

The multi-stage spring 130 is coupled to the second opening 112. The multi-stage spring 130 is formed of two portions having different pitches between the respective winding coils. The multi-stage spring 130 is composed of a first end compression spring portion 131 in which each pitch is densely formed and a second end tension spring portion (132).

The first-stage compression spring portion 131 is screwed to the first screw portion 113, a portion of which protrudes to the outside of the sensor housing 110 and a portion of which is formed in the second opening portion 112.

It is necessary to couple the spring to the sensor housing 110 by a separate part by screwing a part of the first-stage compression spring part 131 with the first screw part 113 formed inside the sensor housing 110 There is an advantage that the spring can be joined with a simple structure.

The first stage compression spring portion 131 of the second stage tension spring portion 132 is formed to be slightly smaller in outer diameter and can enter the sensor housing 110 without interference with the first screw portion 113 . The second end tension spring 132, which is inserted into the sensor housing 110, is assembled in a state of being supported by the connector 141 coupled to the sensor rod 120.

Accordingly, when the sensor rod 120 hits the inner side wall of the mold or contacts the obstacle, the second end tension spring portion 132 supported by the sensor rod 120 can be retracted while being compressed, thereby preventing the sensor rod 120 from being damaged .

The sensor cable 140 is connected to the sensor rod 120 by a connector 141 and is formed by covering two metal wires having two terminals 142 with a synthetic resin material.

A method of assembling and using the thermocouple sensor for a mold thus formed will now be described.

The sensor rod 120 coupled to one end of the sensor cable 140 inserted into the multi-stage spring 130 is installed to be exposed through the first opening 111 of the sensor housing 110, When the multi-stage spring 130 is rotated in one direction by a screw coupling method after the first spring 132 is disposed in the second opening 112 of the sensor housing 110, a part of the first spring compression spring portion 131 of the multi- The multi-stage spring 130 can be firmly coupled to the sensor housing 110 while being screwed with the first screw thread 113 of the sensor housing 110. [

Accordingly, the sensor cable 140 is protected by the multi-stage spring 130 at one end of the sensor housing 110, thereby reducing the possibility of short circuit of the sensor cable 140 during long-term use.

In addition, since the multi-stage springs 130 can be fastened to the sensor housing 110 by a simple screw coupling method, the number of parts can be reduced, resulting in a reduction in manufacturing cost.

Furthermore, the second-stage tension spring 132 can be compressed when the sensor rod 120 is retracted, thereby preventing the sensor rod 120 from being damaged.

In addition, since the second and third threaded portions 114 and 115a having different diameters are formed on the outer circumferential surface of the sensor housing 110, there is an advantage that the sensor housing 110 can be applied to two kinds of holes formed in the mold .

Therefore, according to the present invention, it is possible to provide a mold thermocouple sensor which can be easily assembled, improved in durability, and easy to install in a mold.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
