Description

Technology Field

[0001] This specification relates to a mold, and more specifically, to a mold for forming a block filter using a socket for forming a water purification block filter into a hollow cylindrical shape. Background Technology

[0002] Unless otherwise indicated in this specification, the contents described in this section are not prior art for the claims of this application, and are not to be recognized as prior art simply because they are included in this section.

[0004] Generally, a hollow cylindrical block water filter is installed in a water purifier, etc., and as raw water such as tap water flowing into the filter housing from the outside passes through the internal water filter in a radial direction, chlorine, organic matter, various odors, etc. contained in the raw water are removed, and the purified water from which foreign substances have been filtered is discharged to the outside through the upper or lower holder outlet along the hollow water passage.

[0005] Although not shown in the drawings, block filters used in household water purifiers are molded to have various sizes of outer and inner diameters.

[0006] As an example, a molding device (mold or jig) for molding a hollow cylindrical block water purification filter includes an outer diameter molding section for molding the outer diameter of the water purification filter and an inner core coupled to the outer diameter molding section, so that the main raw material and auxiliary raw material mixed are filled into the filling section between the outer diameter molding section and the inner core to mold the block water purification filter into a hollow cylindrical shape.

[0007] As mentioned above, in order to mold block water purification filters having various sizes of outer and inner diameters, there is a disadvantage in that molds for the outer diameter forming part and the inner core must be possessed with various specifications corresponding to the size of the block water purification filter.

[0008] As a result, the cost of manufacturing molds of various specifications corresponding to the size of the block water purification filter—namely, the outer diameter forming part and the internal core—increases, and there is a problem of having to secure storage space to store molds of various specifications.

[0010] A method for manufacturing a high-performance carbon block filter is disclosed in Korean Registered Patent Publication No. 10-0785686. The problem to be solved

[0011] The embodiments of this specification relate to a mold for forming block filters using a socket, which enables the molding of block filters of various sizes in the form of hollow cylinders using the socket. means of solving the problem

[0012] According to one embodiment of the present specification, in order to achieve the above and other purposes of the present specification,

[0013] A block filter molding die for forming a hollow cylindrical block filter having an internally hollow water passage hole corresponding to the core, wherein a mixed material filled in a space formed inside the core of the mold is pressed by a punch connected to a press:

[0014] A pipe-shaped mold formed with both ends open and a space for filling mixed raw materials, for forming the outer shape of a block filter;

[0015] A core formed inside the above mold and for forming the inner diameter of the block filter;

[0016] A heater installed in at least one location inside or outside the mold or inside the core, for heating the mold or core when power is applied;

[0017] The present invention provides a block filter molding mold using a socket, characterized by including at least one socket formed concentrically inside the mold and detachably coupled so as to correspond to various sizes of the block filter and to ensure compatibility of the mold. Effects of the invention

[0018] A block filter molding die using a socket according to an embodiment of the present specification having the above-described configuration has the following advantages.

[0019] By utilizing sockets of various sizes to form hollow cylindrical block filters of various sizes, the production of molds required for the block filter sizes is minimized, thereby reducing costs and eliminating the need for a large storage space to store multiple molds.

Specific details for implementing the invention

[0021] Hereinafter, a mold for forming a block filter using a socket according to a preferred embodiment of the present specification will be described in detail with reference to the attached drawings.

[0023] Referring to FIGS. 1 to 5, a mold for molding a block filter using a socket according to one embodiment of the present specification

[0024] A block filter molding die for forming a hollow cylindrical block filter having an internally hollow water passage hole corresponding to the core, wherein a mixed material filled in a space formed inside the core of the mold is pressed by a punch (not shown) connected to a press:

[0025] A pipe-shaped mold (30) for forming the outer shape of a block filter (20), having a space (10) formed with both ends open and filled with mixed raw materials (for example, activated carbon and a binder (LDPE, HDPE, UHMWPE, etc.) may be used);

[0026] A core (40) formed inside a mold (30) and for forming the inner diameter of a block filter (20);

[0027] A heater (50) installed on the outside or inside of the mold (30) or inside the core (40), for heating the mold (30) or the core (40) when power is applied;

[0028] Sockets (60) formed concentrically inside the mold (30) to correspond to various sizes of block filters (20) and to be detachably coupled so as to have compatibility with the mold (30);

[0029] It is characterized by including a fixing plate (70) mounted on the top of the mold (30) to prevent the socket (60) from detaching from the mold (30).

[0031] According to a more preferred embodiment, the device further comprises a guide rail (80) (formed in a concave shape, for example) and a guide (90) (formed in a convex shape, for example) formed axially on the inner circumference of the mold (30) and the outer circumference of the socket (60) so as to correspond to each other to prevent the socket (60) from rotating inside the mold (30) described above.

[0032] As a result, the socket (60) inside the mold (30) is prevented from rotating due to the interlocking of the guide rail (80) and the guide (90), so that when a heater (not shown) is installed inside the socket (60), the heater can maintain a set position.

[0034] The invention is further characterized by including a temperature sensor (100) mounted on the outer surface of the aforementioned mold (30) and for detecting the temperature of the mold (30) and transmitting a detection signal to a controller (not shown) to turn the heater (50) on or off according to the detected current temperature.

[0035] That is, the heater (50) can be controlled to turn off when the current temperature detected by the temperature sensor (100) is higher than the set temperature, and to turn on when the current temperature detected by the temperature sensor (100) is lower than the set temperature.

[0036] At this time, the temperature sensor (100) can be divided into multiple parts corresponding to the heater (50) and mounted so that they can be controlled independently of each other.

[0038] The aforementioned socket (60) is characterized by having an outer diameter that is equal to the inner diameter of the mold (30) or a smaller size than the inner diameter of the mold (30).

[0039] As a result, when assembling or separating the socket (60) from the mold (30), it is easy to detach, thereby improving workability.

[0041] Hereinafter, an example of using a mold for forming a block filter using a socket according to one embodiment of the present specification will be described with reference to the attached drawings.

[0043] As shown in FIGS. 1 to 5, the main raw materials, activated carbon and binder (LDPE, HDPE, UHMWPE, etc.), and various auxiliary raw materials (for example, lead removal material (ATS), reduced water mineral leaching material (ceramic powder), antibacterial material (silver-lite, etc.) may be used to provide water purification performance) can be weighed in a precise electronic scale and then uniformly mixed using an industrial precision mixer to mix the raw materials for molding the block filter (20) (see S10).

[0045] As in S20, the mold (30) is heated to a preset temperature by a heater (50; 50a, 50b, 50c) mounted inside the mold (30).

[0046] At this time, the temperature of the heater (50) can be adjusted to maintain a temperature corresponding to the melting point of the binder forming the mixed raw material, or a temperature at which the binder can reach a level of cross-linking that connects the activated carbon particles to each other.

[0047] Although not shown in the drawing, the aforementioned heater (50) can be mounted on the outer surface of the mold (30) and used.

[0049] As in S30, a mixed material can be filled into the space (10) of the mold (30) using an unillustrated material injector, that is, the space (10) between the innermost socket (60c) among the sockets (60; 60a, 60b, 60c) accommodated in the mold (30) and the core (40).

[0050] The aforementioned core (40) is used to form a water passage hole (not indicated in the drawing) inside the block filter (20) shown in FIG. 5.

[0051] At this time, since the mold (30) and socket (60) are already heated to an arbitrary temperature by the heater (50), the mixed raw material can be filled from the bottom of the socket (60c), which is closed at the bottom by the bottom plate (110) formed at the bottom inside the mold (30).

[0053] As in S40, the shape of a hollow cylindrical block filter (20) in which an internal water passage is formed by the core (40) can be formed by pressing the mixed raw material filled in the space (10) of the socket (60c) with a punch (not shown) connected to a press not shown.

[0054] At this time, the technical content of forming a hollow cylindrical block filter (20) with an internally hollow water passage hole by pressurizing the mixed raw material filled in the space (10) of the socket (60c) by a punch connected to a press is commonly used in the technical field to which this specification belongs, so a detailed description of its configuration is omitted.

[0055] As shown in FIGS. 2 to 4, when molding a hollow cylindrical block filter (20) having various outer and inner diameter sizes, the same mold (30) can be recycled.

[0056] To explain this in detail, a socket (60c) corresponding to the outer diameter size of the aforementioned block filter (20) can be coupled inside the mold (30). At this time, the sockets (60a, 60b) are jig sockets used to fill the gap between the socket (60c) and the mold (30).

[0057] That is, if the outer diameter of the block filter (20) to be molded is larger than the inner diameter of the socket (60c), the socket (60c) among the sockets (60) coupled to the mold (30) becomes unnecessary.

[0058] As a result, when the outer diameter size of the block filter (20) to be molded matches the inner diameter size of the socket (60b), the sockets (60a, 60b) are combined in the mold, and by mounting the core (40) in the center of the socket (60b), a block filter (20) having an outer diameter corresponding to the inner diameter of the socket (60b) can be molded.

[0059] Meanwhile, if the outer diameter of the block filter (20) to be molded is larger than the inner diameter of the socket (60b), the socket (60b) among the sockets (60) coupled to the mold (30) becomes unnecessary.

[0060] As a result, when the outer diameter size of the block filter (20) to be molded matches the inner diameter size of the socket (60a), the socket (60a) is attached to the mold, and by mounting the core (40) in the center of the socket (60a), it is possible to mold a block filter (20) having an outer diameter corresponding to the inner diameter of the socket (60a).

[0061] As described above, without separating the socket (60) from the mold (30), the heating operation of the mold (30) is continuously performed due to the operation of the heater (50) installed in the mold (30), so that the block filter (20) inside the core (60) of the mold (30) can be molded and hardened into a hollow cylindrical shape.

[0063] As in S50, the socket (60) and the core (40) are separated from the aforementioned mold (30). A hollow cylindrical block filter (20) can then be withdrawn from the aforementioned mold (30).

[0064] At this time, since the technical details for separating the aforementioned core (40) and socket (60) are commonly used in the technical field to which this specification belongs, a detailed description of their configuration is omitted.

[0065] As described above, the technical content including the configuration of forming a hollow cylindrical block filter (20) with a water passage hole formed in the inner center by a core (40) formed in the center of any one of the sockets (60; 60a, 60b, 60c) detachably coupled to the mold (30), the configuration of heat-treating the block filter (20) formed into a hollow cylindrical shape by a heater (50) so that the mixed raw material filled in the socket (60) is pressurized and the block filter (20) formed into a hollow cylindrical shape is hardened, and the configuration of separating the socket (60) from the mold (30) to withdraw the block filter (20) formed into a hollow cylindrical shape from the mold (30) is a configuration commonly used in the technical field to which this specification belongs, so a detailed description of these configurations is omitted.

[0067] Hereinafter, although the foregoing specification has been described with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the specification without departing from the spirit and scope of the specification as set forth in the following claims.
