Description

[0001] Thermo couple sensor for mold [0002]

The present invention relates to a thermocouple sensor for a mold, more specifically, to a thermocouple sensor for a mold which is formed to be assembled with a small number of parts and which requires no complex machining process and is easy to install on 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 molds disclosed in the Utility Model No. 20-0462931 has a problem that a complex machining process such as a hexagonal wrench part to be combined with a tool is required to be performed .

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 (a) is a cross-sectional view showing a state before the fastening is completed in the mold hole,
3 (b) is a cross-sectional view showing a state in which the fastening is completed in the mold hole.

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

FIG. 1 is an exploded perspective view of FIG. 1, FIG. 3 (a) is a cross-sectional view showing a state before fastening to a mold hole, and FIG. 3 (b) is a cross-sectional view showing a state in which the fastening is completed in the mold hole.

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 exposed to one side of the sensor housing 110, A nut type pressing member 140 which is coupled to the other side of the sensor housing 110 and a fixing cap 130 which is provided between the sensor housing 110 and the nut type pressing member 140, And the other end of the leaf spring S is disposed on the outer side of the sensor housing 110. The plate spring S is supported by the nut type pressing member 140 and is tightly coupled to the mold hole formed in the metal mold, A spring 150 and a sensor cable 160 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-like shape so as to penetrate the inside of the sensor housing 110, and a screw portion 111 is formed at one end.

The fixed cap 130 serves to fix and support the sensor rod 120 exposed at one side of the sensor housing 110 so that the sensor rod 120 is exposed to one side of the sensor housing 110.

The fixed cap 130 is inserted into the inner wall of the sensor housing 110 in an interference fit manner while the outer stepped portion 131 is hooked to one end of the sensor housing 110, A sensor rod 120 for passing the sensor rod 120 through the sensor rod 120 and a sensor rod 120 for passing the sensor rod 120 through the sensor rod 120, And an inner stepped portion 133 which is formed to be stepped on the stepped portion.

Since the sensor housing 110 is not required to be separately machined to fix the sensor rod by assembling the fixed cap 130 to the sensor housing 110 in a assembled manner, the manufacture of the thermocouple sensor 100 can be simplified .

The nut type pressing member 140 is formed so as to pass through the inside and includes an inner threaded portion 143 to be screwed to the threaded portion 111 formed on the sensor housing 110 on the other side of the sensor housing 110, A locking handle engagement groove 141 is formed in an inner side of the sensor housing 110 and an inner stepped portion 142 is formed at an inner side of the sensor housing 110 to prevent a side of the sensor housing 110 from being pushed.

The locking handle engagement groove 141 is used to engage the nut type pressing member 140 with the sensor housing 110 by engaging with a locking handle (not shown) having a correspondingly formed locking projection (not shown).

The plate spring S is formed so as to pass through the inside thereof, and is curved in one direction. When the nut type pressing member 140 is interposed between the nut type pressing member 140 and the sensor housing 110 so that the nut type pressing member 140 is screwed with the threaded portion 111 of the sensor housing 110, The edge of the leaf spring is closely contacted with the inner side surface of the mold hole H formed in the mold. Therefore, the thermocouple sensor 100 can be fixed to the mold hole by the expansion of the leaf spring S without forming a separate thread in the mold hole so as not to be coupled to the thermocouple sensor 100.

The spring 150 is supported at one end by the sensor rod 120 and the other end is disposed at the outer side of the sensor housing 110. The spring 150 is formed of two portions having different diameters. The spring 150 has a relatively large diameter, A first spring portion 151 that is engaged with the socket 140 and a second spring portion 152 that is relatively small in diameter and one side of which is supported at one end of the sensor rod 120.

The second spring portion 152 is disposed so that there is no interference with the inner wall of the sensor housing 110 so that the second spring portion 152 is free to move when the sensor rod 120 is pressed and pushed in the sensor housing 110. Therefore, it is preferable that the diameter is smaller than that of the first spring portion 151 that is engaged with the nut-shaped pressing member 140. [

Therefore, when the sensor rod 120 hits the temperature measurement object T or touches the obstacle, the second spring portion 152 supported by the spring can be retracted while being compressed, thereby preventing the sensor rod 120 from being damaged .

The sensor cable 160 is connected to the sensor rod 120 by a connector 121 and is formed by covering two metal wires having two terminals 162 with a synthetic resin material.

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

First, the fixed cap 130 is coupled to one side of the sensor housing 110 in a forced fit manner. The sensor rod 120 coupled to one end of the sensor cable 160 into which the spring 150 is inserted is installed to be exposed through the sensor rod passing hole 132 formed in the one fixing cap 130 of the sensor housing 110 A plate spring S and a nut type pressing member 140 are roughly coupled to the other side of the sensor housing 110 and then the thermocouple sensor 100 is placed in the mold hole H formed in the mold.

When the nut type pressing member 140 is rotated by rotating the nut type pressing member 140 by engaging the fastening handle with the nut type pressing member 140, So that the thermocouple sensor 100 can be firmly fixed to the inner surface of the mold hole H. As shown in FIG.

Therefore, according to the present invention, it is possible to provide a mold thermocouple sensor which is formed to be assembled with a small number of parts, and which does not require a complicated cavity and is 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.
