Description

TECHNICAL FIELD

[0001] The present application relates to a hydrostatic pressure device provided with a non-contact stirring and conveying system to enable smooth circulation of a pressurized medium, and more particularly, to a hydrostatic pressure device provided with a non-contact stirring and conveying system, which includes an external container formed with an insertion groove and receiving a pressurized medium to the insertion groove, an upper cover coupled to the insertion groove, an internal container inserted into the insertion groove coupled to the lower portion of the upper cover, a magnetic driver operating in a non-contact manner by a magnetic force, and a circulation portion operated by the magnetic driver to circulate the pressurized medium, thereby minimizing the temperature deviation of the pressurized medium inside the insertion groove, that is, the internal container, to enable compression molding to be performed at a uniform temperature. BACKGROUND

[0002] Generally, a hydrostatic pressure device, in other words, an isostatic pressure press device, is a device for molding a powder such as metal or ceramic, and particularly for manufacturing a chip part, and also for sterilization of food, etc., which injects a gas or a fluid, that is, a pressurized medium, into the inside of an internal container in a state where an object to be processed is put inside the internal container, to perform compression molding by the pressure of the gas or the fluid.

[0003] In the conventional isostatic pressure press device, Korean Patent Publication No. 10-2007-0112718 discloses an "isostatic pressure press device" provided with a heat insulator forming a processing chamber accommodating an object to be processed, a pressure vessel covering the heat insulator, a heating device heating the pressure vessel, and a pressure medium supply device capable of supplying a pressure medium to the inside of the pressure vessel, and configured to provide a pressure medium introduction space capable of introducing the pressure medium between the heat insulator and the pressure vessel, the processing chamber is communicated to the pressure medium introduction space via a communication hole formed in the upper portion of the heat insulator, and the pressure medium supply device is communicated to the pressure medium introduction space via a pressure medium introduction port formed in the lower portion of the pressure vessel.

[0004] The above conventional isostatic pressure press device heats the pressure medium by the heating device and supplies it to the pressure medium introduction space, and also supplies the heated pressure medium to the pressure vessel, so that the press molding of the object to be processed can be performed in a heated state.

[0005] However, in the conventional isostatic pressurizing device described above, in order to seal the pressure vessel, the upper cover and the lower cover need to be coupled to the upper and lower portions of the main body, which requires a fastening structure that fastens the upper cover and the lower cover to each other to prevent them from being separated from the pressure vessel, i.e., the main body, or an external container that is separately provided to support them to prevent them from being separated, thus causing not only an increase in manufacturing cost due to a complicated structure but also a problem in that a long time is required to move the workpiece into or out of the pressure vessel due to such a structure.

[0006] Further, in the conventional isostatic pressurizing device described above, in fact, if the upper cover and the lower cover are not firmly coupled to the main body, there is a risk of an accident such as explosion due to high pressure of the pressure medium, and a safety device and a firm coupling structure therefor are required.

[0007] Meanwhile, the conventional isostatic pressurizing device described above directly heats the pressure vessel in order to heat the workpiece, thus not only requiring a long time to heat the workpiece but also causing a problem in that heat loss is seriously wasted and it is difficult to heat the workpiece at a uniform temperature.

[0008] In other conventional isostatic pressurizing devices, a technique of circulating the pressure medium by forming a circulation path in an inner container that accommodates the workpiece is disclosed, but there is a problem in that the pressure vessel releases heat, and the pressure medium having a low temperature is circulated to be contacted when pressure is increased, thus causing a problem in that temperature accuracy deteriorates.

[0009] That is, the conventional isostatic pressurizing device, although circulating the pressure medium or heating the pressure vessel in a manner that the workpiece can be heated at a uniform temperature, not only cannot smoothly perform circulation of the pressure medium using the circulation path, but also has a problem in that it is difficult to uniformly heat the pressure medium when the pressure vessel is heated.

[0060] Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the Figures 1 to 17 The present application will be described in detail.

[0061] The outer container 100, which is a main constituent element for implementing the present application, is formed with an insertion groove 110 at an upper portion, and at least one first serration 120 is protrusively formed at an inner circumferential surface of the insertion groove 110, and a pressurized medium is supplied to the insertion groove 110 from a supply portion 10, which is connected to a lower portion by a connection pipe (not shown) and receives the pressurized medium to the lower portion of the insertion groove 110, an inner container 300, which will be described later in detail, is inserted into the insertion groove 110, and an upper cover 200, which will be described later in detail, is combined to the insertion groove 110, thereby sealing the insertion groove 110 in a state of maintaining airtightness.

[0062] If the insertion groove 110 is described again, it is formed in the outer container 100 in a manner of being open at an upper portion, so that the inner container 300 and the upper cover 200, which will be described later in detail, are entered from the upper portion and are sealed by the upper cover 200.

[0063] The first serration 120 is protrusively formed at least one at the inner circumferential surface of the insertion groove 110, and preferably, two or more first serrations 120 are formed, so as to be able to more stably and firmly combine the upper cover 200, which will be described later in detail, and in the present application, it will be described on the basis that four first serrations 120 are formed.

[0064] At this time, the first serration 120 can be formed in the shape of a general thread, and can be formed in an inclined manner or can be formed in a horizontal direction, i.e., in the direction of the inner periphery of the insertion groove 110, without being inclined, and can be formed in any method as long as it can maintain a state of being firmly combined to form airtightness when the upper cover 200, which will be described later in detail, is inserted into the insertion groove 110 and is combined by being rotated, and in the present application, it will be described on the basis that the first serration 120 is formed in a horizontal direction and is protrusively formed in the direction of the inner periphery of the insertion groove 110.

[0065] Meanwhile, in the insertion groove 110, since at least one first serration 120 is protrusively formed on the inner circumferential surface, an inner circumferential surface on which the first serration 120 is not formed is formed, which allows a gap space 112 to be formed on the inner circumferential surface on which the first serration 120 is not formed when the upper cover 200 to be described later is coupled, the gap space 112 allowing a fixing pin member 600 or a cylinder pin 700 to be inserted to prevent rotation of the upper cover 200, thereby enabling an effect of being able to stably maintain a state in which the upper cover 200 is coupled.

[0066] The upper cover 200, which is a main constituent element for implementing the present application, is coupled as it is rotated after being inserted into the insertion groove 110 of the outer container 100, seals the lower portion of the insertion groove 110, and enables airtightness to be formed in the lower portion of the insertion groove 110 by locating the inner container 300 to be described later in the lower portion of the insertion groove 110, so that the processed object can be molded by the pressurized medium supplied and filled in the insertion groove 110.

[0067] More specifically, the upper cover 200 of the present application is protrusively formed with at least one second serration 210 corresponding to the first serration 120 on the outer circumferential surface, and seals the upper portion of the insertion groove 110 as the first serration 120 and the second serration 210 are engaged, to form airtightness in the lower portion of the insertion groove 110, the second serration 210 being inserted into the insertion groove 110 after being located on a perpendicular line on which the first serration 120 is not formed, and being coupled to the outer container 100 by being rotated by the rotating cylinder 230 to be described later so that the first serration 120 and the second serration 210 are engaged.

[0068] At this time, an inclined step (not shown) is formed on the inner circumferential surface of the insertion groove 110, and an inclined surface corresponding to the inclined step is formed on the lower outer circumferential surface of the upper cover 200, so that the upper portion of the insertion groove 110 is sealed as the upper cover 200 is coupled to form airtightness in the lower portion, and when the inner container 300 to be described later is inserted into the insertion groove 110 in a state of being coupled to the lower portion of the upper cover 200, the lower portion of the insertion groove 110 on which airtightness is formed, so that the processed object is molded by the pressurized medium.

[0069] That is, the upper cover 200 can seal the upper portion of the insertion groove 110 to form airtightness in the lower portion by being simply inserted into the insertion groove 110, and can be coupled as the second serration 210 is engaged to the first serration 120 by being rotated, and can stably maintain a state in which airtightness is formed in the lower portion of the insertion groove 110.

[0070] The second sawtooth part 210 is formed in correspondence with the number of the first sawtooth part 120 and is formed to be engaged with the first sawtooth part 120.

[0071] In the upper cover 200 of the present application, since at least one second sawtooth part 210 is protrusively formed on the outer circumferential surface, the outer circumferential surface on which the second sawtooth part 210 is not formed is formed, and this forms the gap space 112 together with the insertion groove 110 after the first sawtooth part 120 and the second sawtooth part 210 are engaged and combined as described above.

[0072] In relation to the above, the first sawtooth part 120 and the second sawtooth part 210 are each formed by vertically arranging a plurality of sawteeth 122, 212, and thus, when the upper cover 200 is rotated, the sawteeth 212 of the second sawtooth part 210 enter between the sawteeth 122 of the first sawtooth part 120 and are engaged and combined.

[0073] At this time, the sawteeth 122, 212 are characterized in that they are formed in a trapezoidal shape in which the thickness decreases in the protruding direction, thereby achieving the effect of being able to maintain a more stable combined state, i.e., an engaged state.

[0074] Specifically, the sawteeth 122, 212 are characterized in that they are formed in a trapezoidal shape in which the thickness decreases in the protruding direction, and the lower surface is formed at an angle of 40 to 50° with respect to the horizontal surface, and the upper surface is formed at an angle of 0° with respect to the horizontal surface, thereby enabling a more stably combined state when pressure is generated as a pressurized medium is filled in the closed lower portion of the insertion groove 110, and most preferably, 45° is formed, thereby enabling a stably and firmly combined state.

[0075] Further, the sawteeth 122, 212 are characterized in that the sawteeth 122, 212 vertically arranged and the distance between the sawteeth 122, 212, i.e., the pitch, is 55 to 65 mm, which together with the aforementioned angle of the lower surface enables a more securely and firmly combined state, and most preferably, 60 mm is formed, thereby enabling a more stably and firmly combined state.

[0076] Further, the sawteeth 122, 212 are characterized in that the length of the protrusion, i.e., the length from the inner circumferential surface of the insertion groove 110 to the end, from the outer circumferential surface of the upper cover 200 to the end, is 35 to 37 mm, which together with the aforementioned angle of the lower surface and the pitch enables a more securely and firmly combined state, and most preferably, 36 mm is formed, thereby enabling a more stably and firmly combined state.

[0077] Specifically, if the second sawtooth part 210 is described in terms of shape, the sawtooth 212 is characterized in that the lower part is formed to be inclined upward toward the convex direction, i.e., the outer side direction of the upper cover 200, and the upper part is formed to be parallel to the horizontal plane, and is formed in a trapezoidal shape to achieve the effect of being able to maintain a more stable and firm combined state as described above.

[0078] At this time, the sawtooth 122 of the first sawtooth part 120 is formed in a shape corresponding to the sawtooth 212 of the second sawtooth part 210, in other words, is the same in shape as the sawtooth 212 of the second sawtooth part 210, but the upper and lower parts are formed in a reversed shape.

[0079] On the other hand, as shown in Figure 6 The upper cover 200 of the present application can include a ventilation part (not shown) that can discharge air or pressurized medium, etc. inside the insertion groove 110 to the outside when inserted in the insertion groove 110 of the outer container 100.

[0080] As shown in Figure 6 The ventilation part can include a check valve (not shown) that is elastically supported in the upward direction by an elastic member (spring) so as to be more firmly closed when pressure is generated by air or pressurized medium, etc. inside the insertion groove 110, and a discharge passage (not shown) that is formed in the lateral direction of the upper cover 200 in communication with the upper part of the check valve, and the upper cover 200 can further include a control cylinder (not shown) that is provided at the upper part and connected to the check valve to open or close the check valve.

[0081] At this time, the outer container 100 is formed with a discharge flow path (not shown) corresponding to the discharge passage so as to be able to discharge and remove air or pressurized medium discharged through the discharge passage to the outside.

[0082] In relation to the above, the hydrostatic pressure device of the present application is characterized by including a base frame 220 that is rotatably coupled to the upper part of the upper cover 200 with respect to the upper cover 200, a rotation cylinder 230 that is provided to the lower surface of the base frame 220 in a manner that can rotate in the horizontal direction in the rearward direction, and the front of a connecting rod 232 is connected to the upper surface of the upper cover 200, and a limit sensor 240 that is provided to the base frame 220 to sense the end of the connecting rod 232 of the rotation cylinder 230.

[0083] The base frame 220 is rotatably coupled to the upper part of the upper cover 200 with respect to the upper cover 200, in other words, the base frame 220 is rotatably coupled to the upper part of the upper cover 200 and stably supports the upper part of the upper cover 200 when the upper cover 200 is rotated by the rotation cylinder 230.

[0084] At this time, the upper portion of the upper cover 200 is coupled through the base frame 220, preferably in a manner of stably rotating by a bearing (not shown).

[0085] The rotation cylinder 230 engages the first and second serrated portions 120 and 210 by rotating the upper cover 200, so that the upper cover 200 is coupled to the outer container 100, i.e., the insertion groove 110.

[0086] At this time, the rear of the rotation cylinder 230 is fixedly coupled to the lower surface of the base frame 220, and is coupled in a manner of being rotatable in the horizontal direction, and the front of the link 232 is connected to one side or the other side of the upper surface of the upper cover 200 in a manner of being rotatable in the horizontal direction, so as to rotate the upper cover 200 by the operation of the link 232.

[0087] In addition, the rotation cylinder 230 includes a rear bracket (not shown) fixedly coupled to the lower surface of the base frame 220, and a rear rotatable in the horizontal direction coupled to the rear bracket.

[0088] In addition, the rotation cylinder 230 includes a rear rotatable in the horizontal direction coupled to the front of the link 232, and a front coupled to one side or the other side of the upper surface of the upper cover 200.

[0089] That is, the rotation cylinder 230 is operated by a control portion or a control panel (hereinafter collectively referred to as a "control portion") that controls the hydrostatic pressure device of the present application, and rotates the upper cover 200 by the link 232, so that the second serrated portion 210 of the upper cover 200 inserted into the insertion groove 110 of the outer container 100 is stably coupled to the first serrated portion 120.

[0090] At this time, the rotation cylinder 230 can include a motion sensing sensor (not shown) provided inside to sense the length of the link 232 entering and exiting, which transmits the sensed length of the link 232 to the control portion, so that the control portion can calculate the angle of rotation of the upper cover 200 based on the operation of the rotation cylinder 230, thereby achieving an effect of being able to confirm whether the upper cover 200 is firmly coupled to the outer container 100.

[0091] The limit sensor 240 is provided to the base frame 220 to sense the end of the link 232 of the rotation cylinder 230, so that it can be confirmed whether the upper cover 200 is accurately rotated by a predetermined angle overlappingly with the motion sensing sensor, thereby achieving an effect of being able to confirm whether the upper cover 200 and the outer container 100 are firmly and accurately coupled.

[0092] Incidentally, since the rear of the front bracket is actually coupled to the front of the link 232, the limit sensor 240 contacts the rear of the front bracket to sense the operation of the rotary cylinder 230.

[0093] Specifically, the limit sensor 240 includes a coupling sensing sensor 242 which senses the end of the link 232, i.e., the rear of the front bracket, when the rotary cylinder 230 operates in a manner that the length of the link 232 is elongated, i.e., when the upper cover 200 is rotated by the rotary cylinder 230 in a manner that the second serration part 210 of the upper cover 200 is engaged with the first serration part 120, and a separation sensing sensor 244 which senses the end of the link 232, i.e., the rear of the front bracket, when the rotary cylinder 230 operates in a manner that the length of the link 232 is shortened, i.e., when the upper cover 200 is rotated by the rotary cylinder 230 in a manner that the second serration part 210 of the upper cover 200 is separated from the first serration part 120.

[0094] That is, the limit sensor 240 allows the coupling sensing sensor 242 and the separation sensing sensor 244 to sense the operation of the rotary cylinder 230 as described above, so that it is possible to confirm whether the upper cover 200 is coupled to or separated from the external container 100, thereby achieving an effect that the molding can be performed more safely.

[0095] Meanwhile, the hydrostatic pressure device of the present application can include a pair of rotation prevention cylinders which are provided to the base frame 220 to prevent the upper cover 200 from rotating after the upper cover 200 is rotated in a forward direction, i.e., in a direction in which the second serration part 210 is engaged with the first serration part 120, or in a reverse direction, i.e., in a direction in which the second serration part 210 is separated from the first serration part 120.

[0096] Specifically, the rotation prevention cylinders are provided to an upper portion of the base frame 220, and links (not shown) are provided to pass through the base frame 220 downward, and the upper cover 200 includes fixing grooves (not shown) which are formed to allow the links of the rotation prevention cylinders to enter and exit after the rotation in the forward or reverse direction, so that, as described before, the rotation of the upper cover 200 can be limited by the rotation prevention cylinders after the upper cover 200 is rotated to obtain more improved stability.

[0097] In relation to the above, the hydrostatic pressure device of the present application includes a lift cylinder 222 provided in one or more of the lower portion of one side or the lower portion of the other side of the base frame 220, and the lift cylinder 222 is controlled by the control portion to lift or lower the upper cover 200 so that the upper cover 200 is stably inserted into or separated from the insertion groove 110 of the external container 100. At this time, it is obvious that the lift cylinder 222 is provided in the lower portion of the front or the rear of the base frame 220, i.e., the lower portion of the base frame 220, and one or more lift cylinders 222 can be provided in a manner to be located outside the external container 100, and thus the number thereof is not limited.

[0098] On the other hand, as described above, the hydrostatic pressure device of the present application is characterized by including a fixing pin member 600 which is inserted into the insertion groove 110, i.e., the gap space 112 formed between the external container 100 and the upper cover 200, when the first serration 120 of the external container 100 and the second serration 210 of the upper cover 200 are engaged and coupled.

[0099] In other words, the fixing pin member 600 is inserted into and coupled to the insertion groove 110 which is not provided with the first serration 120 and the second serration 210, when the first serration 120 of the external container 100 and the second serration 210 of the upper cover 200 are engaged and coupled, i.e., when the upper cover 200 is rotated after being inserted into the insertion groove 110.

[0100] The fixing pin member 600 is inserted into the gap space 112 to restrict the rotation of the upper cover 200 coupled to the external container 100, so that the state in which the upper cover 200 is coupled to the external container 100 can be stably maintained, so that more improved stability can be ensured.

[0101] At this time, when the fixing pin member 600 is coupled to the gap space 112, the base frame 220 can be difficult to be coupled, and thus it is preferable that a through hole (not shown) is formed in the base frame 220 in a manner to correspond to the gap space 112, and the fixing pin member 600 is smoothly inserted into the gap space 112 after the upper cover 200 is coupled to the external container 100 through the through hole.

[0102] Further, the hydrostatic pressure device of the present application is characterized in that at least one cylinder pin 700 is included instead of the fixing pin part 600, the cylinder pin 700 is provided in the insertion groove 110, i.e., the gap space 112 formed between the outer container 100 and the upper cover 200, and is provided through the base frame 220 when the first serration part 120 of the outer container 100 and the second serration part 210 of the upper cover 200 are engaged and combined, and is provided to be located on both sides of the first serration part 120 or the second serration part 210.

[0103] In other words, the cylinder pin 700 is provided through the base frame 220 when the first serration part 120 of the outer container 100 and the second serration part 210 of the upper cover 200 are engaged and combined, i.e., after the upper cover 200 is inserted in the insertion groove 110 and is combined by being rotated, and is provided to be located on both sides of the first serration part 120 or the second serration part 210.

[0104] The cylinder pin 700 is provided in the gap space 112, and is provided to be located on both sides of the first serration part 120 or the second serration part 210 to restrict the rotation of the second serration part 210, so that the state in which the upper cover 200 is combined with the outer container 100 can be firmly maintained, thereby being able to ensure more improved stability.

[0105] At this time, when the cylinder pin 700 is combined with the gap space 112, it can be difficult to combine due to the base frame 220, and it can be difficult to be fixed to the gap space 112, so it is preferable that a through hole (not shown) corresponding to the gap space 112 is formed through the base frame 220 in a manner corresponding to the position in which the cylinder pin 700 is provided by being inserted, and so that the cylinder pin 700 can be smoothly inserted in the gap space 112 after the upper cover 200 is combined with the outer container 100 through the through hole and is fixed.

[0106] Meanwhile, it can be configured to further include a fixing cylinder (not shown) provided at the upper portion of the base frame 220 and lifting the cylinder pin 700, the fixing cylinder being such that the effect of being controlled by the control part so as to be able to maintain the state in which the cylinder pin 700 is stably and firmly provided after the upper cover 200 is inserted in the insertion groove 110 of the outer container 100 is achieved.

[0107] The inner container 300, which is a main component for implementing the present application, is coupled to the lower portion of the upper cover 200 so that the upper cover 200 is inserted into the lower portion of the insertion slot 110 of the outer container 100 when the upper cover 200 is inserted into the insertion slot 110 of the outer container 100, and is formed with a receiving space 310 that receives an object to be processed (not shown) therein, and the object to be processed is molded by a pressurized medium supplied to the inside of the insertion slot 110 when the upper cover 200 is coupled after being inserted into the insertion slot 110 of the outer container 100.

[0108] At this time, the inner container 300 of the present application can be provided with a door (not shown) that can be opened and closed to place the object to be processed in the receiving space 310, and a heating pipe 320 and a cooling pipe 330 that can heat or cool the pressurized medium are provided inside the receiving space 310, and the heating pipe 320 and the cooling pipe 330 are connected to an external heater (not shown) and a cooling device (not shown) that supplies cooling water, respectively, to heat the pressurized medium by the heater or to cool the pressurized medium by circulation of the cooling water.

[0109] Incidentally, the object to be processed is molded by a pressurized medium filled in the lower portion of the insertion slot 110 formed to be airtight, and in particular, the object to be processed received in the receiving space 310 of the inner container 300 is mainly molded by the temperature and pressure of the pressurized medium filled in the inside of the receiving space 310.

[0110] The magnetic driver 400, which is a main component for implementing the present application, is provided in the upper portion of the upper cover 200 and is provided in such a manner that a rotating shaft 410 penetrates the upper cover 200, has a structure that can rotate an object (an object combined with an inner rotating magnet) located inside an outer magnet in a non-contact manner by magnetic force, that is, in a rotating manner of the inner rotating magnet located inside the outer magnet by using magnetic force, the inner rotating magnet is coupled to the rotating shaft 410, and the rotating shaft 410 is connected to an impeller 514 of a circulation part 500 to be described later to rotate the impeller 514.

[0111] Such a magnetic driver of the present application is a technology used in various industrial fields in the past, and a detailed description thereof will be omitted, and circulation of the pressurized medium inside the inner container 300 can be effectively performed by smoothly rotating the impeller 514 of the circulation part 500 to be described later.

[0112] Meanwhile, the rotating shaft 410 is airtightly coupled to the upper cover 200 to prevent the pressurized medium absorbed by the impeller 514 to be described later from leaking, and is rotatably coupled.

[0113] In more detail, the upper cover 200 includes a bushing groove (not shown) formed in the lower surface and formed so that the lower end of the rotating shaft 410 is located, the rotating shaft 410 including a bushing 412 provided to the lower outer periphery and provided to the bushing groove, the bushing 412 functioning as a bearing to allow the rotating shaft 410 to smoothly rotate while sealing the upper portion of the bushing groove, thereby preventing the rotating shaft 410 from causing the pressurized medium to leak.

[0114] The circulation portion 500, which is a main constituent element for implementing the present application, is provided to the lower surface of the upper cover 200 and is provided to be connected to the lower portion of the rotating shaft 410, rotates an impeller 514 to be described later in detail by the aforementioned magnetic driver 400 to allow the pressurized medium filled in the inside of the inner container 300 to be circulated, so that the temperature of the pressurized medium, which is cooled or heated, is uniform, thereby enabling the molding of the workpiece to be performed at a uniform temperature.

[0115] In detail, the circulation portion 500 of the present application includes an impeller member 510 provided to the lower surface of the upper cover 200 and provided to be connected to the lower portion of the rotating shaft 410 to suck the pressurized medium, and a discharge pipe 520 provided to one side or the other side of the impeller member 510 to discharge the sucked pressurized medium to the lower portion of the insertion groove 110.

[0116] Incidentally, the impeller member 510 includes a body 512 provided to the lower surface of the upper cover 200 and formed with a suction hole (not shown) therethrough, and a discharge hole (not shown) formed with the upper portion of the discharge pipe 520 therethrough at one side of the suction hole, and an impeller 514 connected to the lower portion of the rotating shaft 410 and provided to be located at the upper portion of the suction hole of the body 512.

[0117] At this time, the impeller 514 and the rotating shaft 410 are coupled by a coupling bolt 414 passing through the center of the impeller 514 and coupled to the lower surface of the rotating shaft 410, and preferably the coupling bolt 414 is coupled to the rotating shaft 410 by threads in the opposite direction to the rotation direction of the rotating shaft 410 to prevent loosening due to the rotation of the rotating shaft 410.

[0118] Incidentally, it is obvious that the upper cover 200 can include a suction groove 250 formed in the lower surface and provided with the impeller 514 in the suction groove 250 so that the pressurized medium is smoothly sucked by the smooth rotation of the magnetic driver 400, and the suction groove 250 can be formed with the aforementioned bushing groove in the upper portion.

[0119] That is, by the circulation part 500 of the present application, when the impeller 514 is rotated by the operation of the magnetic driver 400, the pressurized medium heated or cooled, of which the temperature is relatively high, located at the upper portion can be moved to the lower portion of the insertion slot 110, that is, the lower portion of the accommodation space 310, after being sucked into the body 512 through the suction hole of the impeller 514 and moving along the discharge pipe 520 provided at the discharge hole, to be circulated, so that the temperature of the pressurized medium can be more effectively uniformized.

[0120] In other words, in the circulation part 500 of the present application, the body is provided at the lower surface of the upper cover 200, and the pressurized medium located at the upper portion of the insertion slot 110, that is, the upper portion of the accommodation space 310, is sucked and then discharged to the lower portion of the insertion slot 110, that is, the lower portion of the accommodation space 310, to circulate the pressurized medium, so that the temperature of the pressurized medium heated or cooled can be more effectively uniformized.

[0121] At this time, the impeller 514 is characterized by including a plurality of blades 514a formed in a radial shape and formed in parallel with a horizontal surface, and a curved portion 514b formed at one end of the blade 514a by being curved downward and formed to be inclined in a rotation direction, through which the curved portion 514b, not only the effect of more smoothly sucking the pressurized medium can be obtained, but also the pressurized medium forming a vortex after being sucked can be moved in the direction of the discharge hole, so that the effect of smoothly moving the pressurized medium sucked through the discharge pipe 520 can be achieved.

[0122] Incidentally, the body 512 includes a guide block 512a provided at the upper surface and provided between the impeller 514 and the discharge hole to guide the sucked pressurized medium in the direction of the discharge hole, the guide block 512a narrows the width of the suction slot 250 toward the other side of the suction slot 250 formed at the lower surface of the upper cover 200, that is, toward the side of the suction slot 250 in which the discharge hole is formed, so that the flow rate of the sucked pressurized medium is further increased, so that the pressurized medium can be more smoothly discharged through the discharge hole, that is, the discharge pipe 520, so that the effect of more effectively circulating the pressurized medium can be achieved.

[0123] Meanwhile, the blade 514a includes a wedge portion 514a-1 formed at the other end and formed to be located at the outer end of the impeller 514 and protruded in the opposite direction of the rotation direction, the wedge portion 514a-1 not only increases the flow rate of the pressurized medium sucked by the curved portion 514b to enable smooth suction, but also prevents the sucked pressurized medium from flowing backward in the lower direction, so that the effect of smoothly moving the sucked pressurized medium in the direction of the discharge hole, that is, the discharge pipe, to be discharged can be achieved.

[0124] On the other hand, the inner side surface of the inner container 300 and the inner side surface of the insertion groove 110 of the outer container 100 are characterized in that a coating layer 20 of a metal or synthetic resin material having high thermal conductivity is included, and as the metal or synthetic resin material forming the coating layer 20, any of materials having high thermal conductivity in general can be used together with a bonding component for the coating layer, and thus detailed description will be omitted.

[0125] Such a coating layer 20 can be coated on the inner side surface of the inner container 300 and the inner side surface of the insertion groove 110 of the outer container 100 to improve the temperature accuracy of the pressurized medium heated or cooled, i.e., to make the pressurized medium have a uniform temperature, thereby achieving an effect that more precise molding can be performed together with the circulation part 500.

[0126] As a result, the hydrostatic pressure device of the present application can make the pressurized medium heated or cooled smoothly circulate through the magnetic driver 400 and the circulation part 500 in a non-contact manner, and in particular, by making the pressurized medium located at the upper portion, which has a relatively high temperature, circulate to the lower portion, the temperature accuracy of the pressurized medium can be more effectively improved, i.e., the temperature can be made more uniform, thereby achieving a more improved molding effect.

[0127] The above description has been made with reference to the preferred embodiments of the present application, but is not limited to the above-described embodiments, and those skilled in the art can implement various modifications without departing from the gist of the present application.
