Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wax enclosure case manufacturing apparatus for a car thermostat,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a wax-encapsulated case for an automotive thermostat, and more particularly to a wax-encapsulated case manufacturing apparatus for an automotive thermostat which is simpler in the process of sealing a wax into a case.

Generally, a thermostat for an automobile is installed in a passage of circulating cooling water in order to maintain the temperature of an engine of an automobile in an optimal state, and automatically opens / closes the passage according to a change of the cooling water temperature inside the engine, Cooling water was used to circulate through the radiator side passageway or bypass passageway to the radiator or engine so that the temperature remains optimal.

That is, it is a device that regulates the temperature of automobile cooling water and used as thermostat in the temperature range of 75 ~ 120 ℃.

More specifically, the thermostat is installed between the internal water chamber of the car engine and the radiator to open and close the cooling water circuit to allow the engine to reach the normal operating temperature quickly, and after reaching the normal operating temperature, The displacement of the valve was changed so that the flow rate of the cooling water flowing to the radiator was automatically adjusted.

As for the thermostat type for automobiles, it can be classified into a known mechanical type or an electronic type, and the application temperature is used according to the kinds of automobiles such as 77 ° C, 82 ° C, 85 ° C, 88 ° C and 102 ° C.

Here, the mechanical type means that the case in which the wax is sealed so as to react with the water temperature of the cooling water is displaced in the piston and displaced as the volume of the enclosed wax melts to change the opening degree of the diaphragm.

In the case of the electronic type, the case in which the wax is sealed so as to react with the water temperature of the cooling water is controlled by the ECU so that the melting point of the wax is controlled by the high temperature cooling water and the built-in control hot wire. Thus, not only the cooling water temperature but also the artificial wax volume change .

In this connection, Patent Document 1 provides a thermostat for an engine of a vehicle, and Patent Document 2 provides a thermostat for a vehicle engine.

However, in the conventional case, in order to manufacture a wax-encapsulated case which is important in the thermostat, it is necessary to construct various devices such as a stirrer, a coagulating mold, a pulverizer and a molding machine, Respectively.

That is, the process of manufacturing the wax-encapsulated case was divided into several places.

Patent Document 1: Registration No. 10-1316360 (Registered on October 1, 2013) Patent Document 2: Registration No. 10-1126253 (Registered on March 6, 2012)

Accordingly, it is an object of the present invention to provide an apparatus for manufacturing a wax-enclosed case for an automotive thermostat which is simple in the process of enclosing wax into a case.

According to an aspect of the present invention, there is provided a portable electronic device including a main body mounted on a ground, a rotating plate exposed on an upper surface of the main body, a rotating motor provided inside the main body, A case supporting member provided on an upper surface of the main body and configured to transfer the case toward the rotating rotating plate and then rotate the rotating plate to stop the rotating plate when the rotating plate is stopped, A dispenser provided on an upper surface of the main body and configured to discharge a liquid wax into the case in a case seated on the seating member when the rotating plate stops rotating and a wax disposed on the upper surface of the main body, A wax supplying member which is provided on the transferring member and is transported by the transferring member when the rotation plate is stopped after rotation, A cooling plate provided on an upper surface of the main body to cool and solidify the liquid wax pressed in the groove forming member when the rotating plate is stopped when the rotating plate rotates, And a case collecting member provided on an upper surface of the main body and collecting a case containing a solid wax when the rotating plate is stopped while the rotation of the rotating plate is stopped while the pressing by the groove forming member is released, Thereby providing an enclosed case manufacturing apparatus.

According to the present invention, the case supplying member supplies the case to a rotating plate rotated by a rotating motor, and the dispenser supplies the wax, which is necessary for the thermostat, in a liquid state depending on the type of automobile from the wax supplying member, The wax-enclosing case is formed by pressing the liquid wax contained in the case with a groove forming member to form a groove, cooling the wax with the cooling fan to solidify the liquid wax contained in the case, There is an effect of collecting by the collection member.

That is, there is an effect that the step of sealing the wax into the case can be performed at once in the manufacturing apparatus of the present invention.

In other words, the manufacturing process of the wax-encapsulated case is simplified and the manufacturing time is greatly reduced, resulting in less facility investment and less facility space.

According to the present invention, since the case is preheated by the fan heater before the liquid wax is introduced, the wax of the liquid rapidly solidifies due to the case of low temperature, thereby preventing the groove forming member from being difficult to form.

That is, the manufacturing defect of the wax-encapsulated case can be reduced.

The present invention has an effect of preventing heat loss from being generated in the wax of the liquid before being discharged to the case and solidifying the wax because liquid wax is accommodated in the second accommodation space of the heated block heater.

That is, there is an effect that the liquid wax is discharged in the dispenser as much as possible and the possibility that the nozzle is clogged is reduced.

Further, when the piston is moved, the liquid wax is stably received in the second accommodation space of the block heater through the check valve.

The present invention has an effect of manually adjusting the wax discharge amount of the liquid through the adjustment member which is caught by the cylinder when moving the piston.

According to the present invention, since the fitting portion of the housing is fitted into the case, the wax of the liquid is pressed by the molding portion of the molding punch to form the groove, so that the wax of the liquid escapes to the outside of the case when the groove is formed.

That is, there is an effect that a liquid wax is embedded in the case in a predetermined amount.

In the present invention, since the fitting portion of the housing is fitted into the case to support the wax, it is possible to reduce the fluctuation of the wax of the liquid during the formation of the grooves, thereby making it possible to stably form grooves in the wax.

Further, since the solidified wax is supported by the fitting portion of the housing irrespective of whether the forming portion of the forming punch is released from the groove of the wax, the wax position of the built-in solid body is prevented from being changed.

That is, there is an effect that the solid wax is stably embedded in the case.

The present invention has an effect that the gap between the fitting portion of the housing and the case is further sealed by the elasticity of the spring supported by the latching jaw and pressed by the washer.

That is, there is an effect that the liquid wax is prevented from being separated from the inside of the case when the groove is formed.

Further, since the fitting portion of the housing further presses the case toward the seat member by the elasticity of the spring, there is an effect that the case is prevented from moving on the seat member due to an external force when the groove is formed.

The case 1 conveyed to the conveyor 40a is heated by the fan heater 41 while being guided by the guide member 40c toward the cylinder member 40b. That is, the case 1 is preheated in advance.

If the pick-up cylinder 40b 'provided on the bracket 40b' 'is rotated by the first and second cylinders 40b' '' and 40b '' when the rotary plate 20 rotates and stops under the control of the rotary motor 21 Backward, and raised and lowered by the support members 31, 31 ', 31', 31 ', 31', 31 '

That is, the case 1 is transferred by the case supply member 40a and is seated on the seat member 31. [

Then, when the rotary plate 20 is rotated and stopped by the control of the rotation motor 21, the dispenser 50 moves the liquid wax 2 supplied from the wax supplying member 60 to the seating member 31 And is discharged in a fixed amount into the fixed case 1.

More specifically, the wax 2 containing the nano powder, the graphite powder, the swelling agent, and the like mixed in the stirring blade 61a in the stirring tank 61 is supplied to the jacket heater 66 and the cartridge heater 67 So that a liquid state is obtained without significant temperature variation.

The piston 52 is moved through the cylinder 51 so as to receive the liquid wax 2 through the inlet 54a of the dispenser 50 and into the second accommodation space 54b.

At this time, the first cylinder rod 51a of the cylinder 51 connected to the piston 52 ascends in the first housing space 53a of the body tube 53, and the second cylinder rod 51a of the second cylinder 51, The cylinder rod 51b also rises.

Also, the check valve 56 is closed so that the second accommodation space 54b and the outlet 54c are not connected, and the second accommodation space 54b is brought into a vacuum state.

The liquid wax 2 is received in the second accommodation space 54b in a fixed amount through the inlet 54a of the dispenser 50 in the supply pipe 60a without a temperature deviation through the block heater 60c.

That is, the liquid wax 2 is accommodated in the second accommodating space 54b in a vacuum state by the pressure of the air supplied into the stirring tank 61.

In addition, the liquid wax 2 contained in the second accommodation space 54b is maintained in a liquid state without a large temperature deviation due to the block heater 54 being heated.

The piston 52 is moved to the cylinder 51 so that the liquid wax 2 contained in the second accommodation space 54b is discharged from the nozzle 55 through the outlet 54c.

At this time, the adjusting member 57 fastened to the second cylinder rod 51b is caught by the outer surface of the cylinder 51, thereby stopping the movement of the piston 52.

Since the case 1 has been preheated by the fan heater 41 in advance, the liquid wax 2 is prevented from solidifying due to heat loss.

Then, when the rotary plate 20 is rotated and stopped by the control of the rotary motor 21, the groove forming member 70 is conveyed by the conveying member 30 and the liquid wax 2 are pressed to form the grooves 2a.

Then, the cooling fan 80 cools the liquid wax 2 in the state where it is joined to the groove forming member 70.

At this time, since the plurality of cooling fans 80 are respectively disposed at the positions where the rotating plate 20 is rotated by the rotation of the rotating motor 21, the liquid wax 2 is quickly cooled. Thus, the liquid wax 2 is solidified as the volume shrinks and gradually decreases.

When the rotary plate 20 is rotated and stopped under the control of the rotary motor 21, the forming punch 71 and the housing 72 of the groove forming member 70 are raised by the conveying member 30.

At this time, since the wax 2 is solidified and the molded portion 71c is completely engaged with the groove 2a of the wax 2, the solid wax 2 rises like the instant formed portion 71c However, it is supported by the fitting portion 72c fitted in the inside of the case 1 and can not be detached from the inside of the case 1. [

The fitting portion 72c of the housing 72 comes out later than the forming punch 71 in the case 1 while the rising pin 73 is guided and hooked to the guide hole 72b.

Further, the groove-formed member 70 is moved backward by the conveying member 30.

That is, pressurization of the case 1 and the solid wax 2 by the groove forming member 70 is released.

The case 1 containing the solid wax 2, that is, the wax-enclosing case 3 is inserted into the case collecting member 90, Is collected.

More specifically, the pick-up cylinder 90a 'provided on the bracket 90a' 'is guided forward, backward and up and down by the first and second cylinders 90a' '' and 90a '' '' The wax-enclosing case 3 is held and transferred to the conveyor 90b.

Then, the case 1 containing the solid wax 2 to be conveyed to the conveyor 90b, that is, the wax enclosure case 3, is guided by the guide member 90c and is discharged.

That is, the wax-encapsulated case 3 is manufactured by the wax-encapsulated case manufacturing apparatus 100 for an automotive thermostat according to the embodiment of the present invention.

Of course, a plurality of wax-encapsulated cases 3 are produced by the wax-encapsulated case manufacturing apparatus 100 for an automotive thermostat.

Thus, as shown in Fig. 15, the wax-encapsulated case 3 is fitted in the groove 2a with the rubber cap 4a accommodating the volume change of the wax 2 which expands or shrinks.

The opening of the case 1 is seamed and sealed after the piston guide 4b is covered with the upper portion of the rubber cap 4a so that the piston 4c is sequentially moved to the piston guide 4b and the rubber cap 4a, .
