It is a drawing to explain the shape.

[0031] Hereinafter, a crosshead (1000) combined with a release agent application device according to the present invention will be described with reference to FIGS. 1 to 12.

[0032] The die-casting mold device (10) is a mold for mass-producing metal parts with complex shapes and high precision, and as shown in FIG. 1, the first mold (11) located at the top and bottom and the second mold (12) located on the left and right sides move to the center (13) to form a product, and there is a problem that the process becomes complicated because a release agent application device for applying a release agent to these molds must be inserted into the ejection port.

[0033] Accordingly, in the present invention, as shown in FIG. 2, a release agent application device (200) is coupled to a crosshead (100) coupled to the front side of a die-casting mold device, thereby simplifying the process of applying a release agent to the mold.

[0034] In other words, the process for applying the release agent has been simplified to enable faster product production.

[0035] At this time, the crosshead (100) may include a head body (110) having a plate shape and having a plurality of guide grooves (111) formed on one side in the thickness direction, and a guide member (120) coupled to the side of the plurality of guide grooves (111), and an extraction hole (112) may be formed in the center of the head body (110).

[0036] To explain in detail, a guide groove (111) is formed on one surface of the head body (110) so that the mold can move stably along the guide groove (111).

[0037] In addition, a guide member (120) is positioned at the edge of the intersection where the guide grooves (111) intersect each other, thereby enabling more stable support for the mold moving along the guide grooves (111).

[0038] At this time, the guide groove (111) includes a first guide groove (111-1) located on the upper side, a second guide groove (111-2) located on the left side, a third guide groove (111-3) located on the lower side, and a fourth guide groove (111-4) located on the right side, and each guide groove can connect an outer end and an extraction hole (112) located in the center.

[0039] And, the mold moving along the passage formed by the guide groove (111) and the guide member (120) is stopped at a certain position by a stopper on the mold device to which the crosshead is attached, and when the mold is in a stopped state, the release agent application device (200) is operated to apply a release agent to the surface of the mold.

[0040] Additionally, as shown in FIGS. 4 and 5, the guide member (120) has a coating device fastening groove (121) formed at the end facing the central area where the extraction hole (112) is formed, so that a release agent coating device (200) is fastened to the coating device fastening groove (121), and the coating device fastening groove (121) has a cut portion (121-1) formed at the end facing the central area where the extraction hole (112) is located, so that the release agent coating device (200) coupled to the coating device fastening groove (121) can discharge the release agent through the cut portion (121-1).

[0041] At this time, the release agent can be applied to a single or multiple molds depending on the angle and range of spraying, and the release agent can be applied to the mold immediately after the manufactured product is ejected through the ejection hole (112), thus having the advantage of minimizing the movement of the mold for applying the release agent.

[0042] In addition, although not shown in the drawing, a shock-absorbing member made of a soft material (sponge) is attached to the surface of the guide member (120) forming the attachment groove (121) of the above-mentioned application device, thereby preventing the release agent application device (200) and the guide member (120) from colliding with each other and being damaged.

[0043] Referring to FIGS. 6 to 9, the release agent application device (200) may include an application device head (210) in which a release agent inlet hole is formed in the longitudinal direction, a release agent supply bar (220) in which a release agent discharge portion (221) is formed in the central area, and a plurality of application nozzles (230) in which a fastening hole is formed in the center to which the release agent supply bar (220) is fitted, and a release agent discharge hole (230-1) is formed in the thickness direction.

[0044] To explain in detail, the release agent introduced through the release agent inlet hole (211) of the coating device head (210) is supplied to the coating nozzle (230) through the release agent discharge part (221) of the release agent supply bar (220), and the release agent supplied to the coating nozzle (230) is sprayed through the release agent discharge hole (230-1) so that the release agent can be coated on the surfaces of molds located in the opposite direction (diagonal).

[0045] Additionally, the above-mentioned release agent discharge section (221) may include a release agent transfer passage (221-1) that extends from one end in the longitudinal direction to the other and communicates with the release agent inlet hole, and a stepped groove (221-2) that exposes the release agent transfer passage (221-1) to the outside.

[0046] To explain in detail, a stepped groove (221-2) is formed and the central and other regions of the release agent transfer passage (221-1) are exposed to the outside, so that the release agent is simultaneously supplied to a plurality of coating nozzles (230) connected to the exposed portion of the release agent transfer passage (221-1).

[0047] At this time, the coating nozzle (230) has a polygonal column shape similar to a nut, and when a release agent discharge hole (230-1) is formed on one side of the polygonal column shape, the release agent is supplied to the release agent discharge hole (230-1) only when the exposed portions of the release agent discharge hole (230-1) and the release agent transfer passage (221-1) are positioned to face each other, so it is obvious that the user can determine the coating nozzle (230) where the release agent is sprayed by adjusting the angle of the coating nozzle (230).

[0048] That is, the number and position of the spray nozzles (230) that spray the release agent can be finely adjusted in accordance with the shape of the mold.

[0049] In addition, the release agent supply bar (220) has a first screw thread formed on the outer surface of the other end in the longitudinal direction, and a second screw thread corresponding to the first screw thread is formed on the inner surface of the bar fastening hole (101) of the crosshead (100) to which the other end in the longitudinal direction of the release agent supply bar (220) is fastened. When the release agent supply bar (220) is screwed into the bar fastening hole (101) while being inserted into the fastening groove (121) of the coating device, the multiple coating nozzles (230) are in close contact with each other, and there is an advantage that the problem of the release agent leaking through the gap formed between the multiple coating nozzles (230) can be minimized.

[0050] Additionally, referring to FIGS. 10 and 11, a plurality of the coating nozzles (230) may include rotation limiting means formed on surfaces that are in close contact with each other.

[0051] To explain in detail, since there is a problem where the spray angle of the release agent changes when the application nozzle (230) rotates due to the force of the release agent being discharged through the release agent discharge hole (230-1) of the application nozzle (230), a plurality of application nozzles (230) are connected by a rotation limiting means so that the angle of the application nozzle (230) can always be maintained at an angle set by the user.

[0052] At this time, the rotation limiting means may be of various forms, and as one embodiment, as shown in FIG. 10, it may include a stopper projection (231) formed circumferentially spaced apart on one side in the longitudinal direction of the coating nozzle (230) and a first stopper groove (232) formed circumferentially spaced apart on the other side in the longitudinal direction of the coating nozzle (230).

[0053] That is, when multiple coating nozzles (230) are in close contact with each other, the stopper projection (231) is fitted into the first stopper groove (232), thereby restricting the individual rotation of the coating nozzles (230).

[0054] In another embodiment, the rotation limiting means may include a polygonal column-shaped stopper lip (233) protruding from one side in the longitudinal direction of the coating nozzle (230), and a second stopper groove (234) formed on the other side in the longitudinal direction of the coating nozzle (230) and having a shape corresponding to the stopper lip (233).

[0055] In addition, the stopper lip (233) may have a sealing member made of rubber or silicone attached to its outer surface to minimize the problem of release agent leaking through the bonding surface between the stopper lip (233) and the second stopper groove (234).

[0056] Referring to FIG. 12, the coating nozzle (230) has a plurality of discharge holes spaced apart in the circumferential direction, and the plurality of discharge holes may have different shapes.

[0057] To explain in detail, a first discharge hole (231-1) having a constant flow path cross-sectional area is formed in the coating nozzle (230), a second discharge hole (231-2) whose cross-sectional area widens as it extends from the inner side adjacent to the fastening hole to the outer side, and a third discharge hole (231-3) consisting of a first flow path (231-3A) formed on the inner side adjacent to the fastening hole and a plurality of second flow paths (231-3B) located on the outer side and connected to the first flow path (231-3A), thereby allowing the user to select and use a discharge hole capable of spraying a release agent in a form suitable for the mold.

[0058] The present invention is not limited to the embodiments described above and has a diverse scope of application. Furthermore, it is understood that anyone with ordinary knowledge in the field to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims.
