Therefore, the door device 1 for an injection molding machine according to the present invention prevents excessive weight of the door 3 from being applied to any one of the up and down rolling mechanisms 42, thereby increasing the operation of the up and down rolling mechanisms 42. lifespan can be further extended.

The up-and-down rolling mechanism 42 may be disposed in the upward direction (direction of arrow UD) with respect to the upper and lower support mechanism 41 . In this case, the upper and lower support mechanism 41 may limit the distance at which the upper and lower rolling mechanism 42 can move in the downward direction (DD arrow direction). The up-and-down rolling mechanism 42 may be disposed in the lower direction (direction of arrow DD) with respect to the upper and lower support mechanism 41 . In this case, the upper and lower support mechanism 41 may limit the distance that the upper and lower rolling mechanism 42 can move in the upward direction (direction of arrow UD).

It can be. That is, the upper and lower rolling member 421 may roll on the outer surface of the upper and lower support mechanism 41 as the door 3 is moved relative to the opening and closing direction (X-axis direction). Accordingly, the door device 1 for an injection molding machine according to the present invention is implemented to reduce friction between the upper and lower rolling mechanism 42 and the upper and lower support mechanisms 41 through the upper and lower rolling member 421 . Therefore, the door device 1 for an injection molding machine according to the present invention increases the ease of moving the door 3 along the opening and closing direction (X-axis direction), and the door 3 and the door 3 It is possible to prevent the operation life of the door 3 from being reduced due to friction between the door frames 2 .

The upper and lower rolling member 421 may be coupled to the upper and lower coupling member 422 through a bearing or the like. The vertical rotation shaft 421a may be formed along the inward and outward directions (Z-axis direction) perpendicular to the opening and closing directions (X-axis direction) and the up-and-down directions (Y-axis direction), respectively. The upper and lower rolling members 421 may be formed to surround the upper and lower coupling members 422 . The upper and lower rolling member 421 may be engaged with the upper and lower support mechanism 41 and rotated.

The upper and lower coupling members 422 are those in which the upper and lower rolling members 421 are rotatably coupled about the vertical rotation shaft 421a. The upper and lower coupling member 422 may function as a shaft for rotating the upper and lower rolling member 421 . The upper and lower coupling member 422 may be rotatably coupled to the door 3 about an upper and lower coupling shaft 422a. The vertical coupling shaft 422a is an axis for rotating the vertical coupling member 422 and may be formed at a position spaced apart from the vertical rotation shaft 421a. Therefore, when the upper and lower coupling member 422 rotates around the upper and lower coupling shaft 422a, the upper and lower rolling members 421 may revolve around the upper and lower coupling shaft 422a. Accordingly, the door device 1 for an injection molding machine according to the present invention can achieve the following operational effects.

First, in the door device 1 for an injection molding machine according to the present invention, as the upper and lower coupling member 422 rotates around the upper and lower coupling shaft 422a, the upper and lower rolling members 421 move the door 3 It is implemented to move along the vertical direction (Y-axis direction) with respect to. Here, the door 3 is moved along the vertical direction (Y-axis direction) when the upper and lower rolling member 421 is moved along the vertical direction (Y-axis direction). Therefore, in the door device 1 for an injection molding machine according to the present invention, the door 3 can be moved along the vertical direction (Y-axis direction) simply by rotating the upper and lower coupling member 422, Ease of aligning the position of the door 3 with respect to the door frame 2 based on the vertical direction (Y-axis direction) can be increased.

This is because the upper and lower rolling member 421 is supported by the upper and lower support mechanism 41 and cannot be moved in the lower direction (DD arrow direction) any longer. Through the above process, the position of the door 3 relative to the door frame 2 can be aligned in the upward direction (direction of arrow UD).

It can be. That is, the inner and outer rolling member 521 may roll on the outer surface of the inner and outer supporting mechanism 51 as the door 3 is moved relative to the opening and closing direction (X-axis direction). Accordingly, the door device 1 for an injection molding machine according to the present invention is implemented to reduce friction between the inner and outer rolling mechanism 52 and the inner and outer supporting mechanism 51 through the inner and outer rolling member 521 . Therefore, the door device 1 for an injection molding machine according to the present invention increases the ease of moving the door 3 along the opening and closing direction (X-axis direction), and the door 3 and the door 3 It is possible to prevent the operation life of the door 3 from being reduced due to friction between the door frames 2 .

The rolling surface is a surface to be supported by the internal and external support mechanism 51 . The rolling surface may face a direction away from the internal/external rotation shaft 521a. The rolling surface may be formed flat based on the vertical direction (Y-axis direction). Accordingly, in the door device 1 for an injection molding machine according to the present invention, as shown in FIG. 9, in a state where the rolling surface is supported by the internal and external support mechanism 51, the internal and external rolling mechanism 52 moves in the vertical direction. Even if it is moved along (the Y-axis direction), the inner and outer rolling mechanism 52 is implemented so that it is not caught on the inner and outer supporting mechanism 51 . Therefore, in the door device 1 for an injection molding machine according to the present invention, after an operator aligns the position of the door 3 with respect to the door frame 2 based on the inward and outward direction (Z-axis direction), the vertical direction Since it is possible to align the position of the door 3 with respect to the door frame 2 based on (Z-axis direction), the ease of aligning the position of the door 3 can be further increased.

The internal/external coupling shaft 522a is an axis for rotating the internal/external coupling member 522 and may be formed at a position spaced apart from the vertical rotation shaft 421a. Accordingly, when the inner/outer coupling member 522 is rotated around the inner/outer coupling shaft 522a, the inner/outer rolling member 521 may revolve around the inner/outer coupling shaft 522a. Accordingly, the door device 1 for an injection molding machine according to the present invention can achieve the following operational effects.

First, in the door device 1 for an injection molding machine according to the present invention, as the inner and outer coupling member 522 is rotated around the inner and outer coupling shaft 522a, the inner and outer rolling member 521 moves the door 3 It is implemented to move along the inward and outward direction (Z-axis direction) with respect to. Here, the door 3 is moved along the inward and outward direction (Z-axis direction) when the inner and outer rolling member 521 is moved along the inward and outward direction (Z-axis direction). Therefore, in the door device 1 for an injection molding machine according to the present invention, the door 3 can be moved along the inward and outward direction (Z-axis direction) only by rotating the inner and outer coupling member 522, Ease of aligning the position of the door 3 with respect to the door frame 2 based on the inward and outward direction (Z-axis direction) can be increased.

Second, the door device 1 for an injection molding machine according to the present invention rotates the inner and outer coupling member 522 even when the inner and outer rolling member 521 is supported by the inner and outer support mechanism 51, thereby rotating the inner and outer direction ( It is implemented to align the position of the door 3 with respect to the door frame 2 based on the Z-axis direction). Accordingly, in the door device 1 for an injection molding machine according to the present invention, the operator aligns the position of the door 3 with respect to the door frame 2 based on the inward and outward direction (Z-axis direction). (3) does not need to be separated from the door frame (2). Therefore, the door device 1 for an injection molding machine according to the present invention not only can further increase the ease of aligning the position of the door 3, but also reduces the time required for aligning the injection molding machine ( The operation rate for 10) can be further increased.

For convenience of description, a case in which the inner and outer rolling mechanism 52 is disposed in the inward direction (direction of arrow ID) with respect to the inner and outer supporting mechanism 51 will be described.

First, as shown in FIG. 7, due to the process of coupling the door 3 to the door frame 2 for the first time or when the door 3 is aged, the inner and outer rolling member 521 is not supported by the internal and external support mechanism 51 and may be disposed at a position spaced apart from the internal and external support mechanism 51 in the inward direction (ID arrow direction).

Next, the operator may rotate the internal/external coupling member 522 around the internal/external coupling shaft 522a. Accordingly, the inner and outer rolling member 521 may revolve around the inner and outer coupling shaft 522a.

Next, as the inner and outer rolling member 521 revolves around the inner and outer coupling shaft 522a, it can be moved in the outward direction (direction of arrow ED). Accordingly, as shown in FIG. 8 , the inner and outer rolling member 521 may be supported by the inner and outer support mechanism 51 .

Next, when the upper and lower coupling member 422 is further rotated around the internal and external coupling shaft 522a in a state where the inner and outer rolling member 521 is supported by the inner and outer support mechanism 51, the door 3 may be moved in the inward direction (ID arrow direction). This is because the inner and outer rolling member 521 is supported by the inner and outer supporting mechanism 51 and cannot move in the outward direction (direction of arrow ED) any longer. Through the above process, the position of the door 3 relative to the door frame 2 can be aligned in the inward direction (ID arrow direction).

The inner/outer coupling member 522 may be coupled to the door 3 through a headless bolt (not shown) or the like. When the internal/external rotation shaft 521a corresponds to the center of the internal/external coupling member 522, the internal/external coupling shaft 522a may be eccentric with respect to the center of the internal/external coupling member 522.

The internal and external manipulation member 523 is to receive an operating force. The internal and external control member 523 can be operated by an operator or the like. The internal and external manipulation member 523 may be coupled to the internal and external coupling member 522 . The internal/external manipulation member 523 may transfer the manipulation force provided from the operator to the internal/external coupling member 522 . Accordingly, the internal/external coupling member 522 can be rotated around the internal/external coupling shaft 522a through the operating force transmitted from the internal/external operating member 523 .

Referring to FIGS. 7 to 9 , the inside and outside control member 523 may be spaced farther from the door 3 than the distance between the inside and outside rolling member 521 from the door 3 . Accordingly, the door device 1 for an injection molding machine according to the present invention can reduce the degree of collision between the operator's hand and the like against the inner and outer rolling member 521 while the operator operates the inner and outer control member 523. have. Therefore, the door device 1 for an injection molding machine according to the present invention can increase the ease and safety of the operation of manipulating the inside and outside manipulation member 523 .

The inner and outer control member 523 may be disposed in the lower direction (direction of arrow DD) with respect to the inner and outer rolling member 521 . A groove into which an operating tool (not shown) such as a wrench or a screwdriver can be inserted may be formed in the internal/external operating member 523 . In this case, the groove into which the operating mechanism or the like can be inserted may be formed to face the lower direction (DD arrow direction).
