Description

Technical Field

[0001] The utility model relates to the sliding field of a front door of an injection molding machine, in particular to a sliding structure of a front door of an injection molding machine. Background Art

[0002] The movable front door of the injection molding machine is a door body that blocks or opens the material collection window. Before injection molding, the movable front door is closed to prevent manual or mechanical entry into the injection molding area. After injection molding, the movable front door is opened to facilitate the removal of the injection molded product.

[0003] Due to production tolerances, the mobile front door may be too tight or too loose after installation. If it is too tight, the friction will be greater and the energy will be more consumed when the mobile front door moves, while if it is too loose, the mobile front door may shake slightly during movement, which is not conducive to long-term use.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 to Figure 3In an embodiment of the utility model, a sliding structure of a front door of an injection molding machine includes a fixed plate 1, and a sliding frame 2 with a hollow structure is integrally formed on the top and bottom of the fixed plate 1. A window 3 is opened on one side of the interior of the fixed plate 1, and the inner cavities of the upper and lower sliding frames 2 are slidably connected with adjustable sliding components. A movable front door 4 is fixedly installed between the two adjustable sliding components, and the movable front door 4 that moves with the adjustable sliding component is used to block and close the window 3 or release the blocking and closing of the window 3; a long strip groove 12 slidably connected to the movable front door 4 is opened at one end of the two sliding frames 2 that are close to each other, and a strip groove 5 is opened in the middle of the end of the two sliding frames 2 that are close to each other.

[0019] In this embodiment, the movable front door 4 is driven to move by a driving device (such as a linear belt driving device). Before the injection molding operation, the movable front door 4 moves to block and close the window 3, thereby forming an effective protective effect. After the injection molding operation is completed, when the injection molded product is taken out, the movable front door 4 is driven by the driving device to move in the opposite direction to open the window 3, so that the injection molded product can be taken out manually through the window 3.

[0020] During the movement of the movable front door 4 , the movable front door 4 drives the two sets of adjustable sliding components to slide axially inside the sliding frame 2 , thereby reducing the friction of the movable front door 4 during the sliding process.

[0021] Please refer to Figure 2 and Figure 3 The adjustable sliding assembly includes two horizontal plates 6 fixedly connected to the upper and lower edges of the back end of the movable front door 4, and the ends of the two horizontal plates 6 away from each other are provided with lifting grooves 7. The adjustable sliding assembly also includes a lifting plate 8 slidably connected to the inner cavity of the lifting groove 7 up and down, and two rotating ears 9 are fixedly installed on the end surface of the lifting plate 8 away from the strip groove 5, and a roller 10 is rotatably connected between the two rotating ears 9. An adjusting bolt 11 is connected to the inside of the horizontal plate 6 at the center of the lifting plate 8, and the adjusting bolt 11 is rotatably connected to the horizontal plate 6. A threaded groove threadedly connected to the adjusting bolt 11 is provided inside the lifting plate 8.

[0022] In this embodiment: after the adjustable sliding assembly is installed in the inner cavity of the sliding frame 2 along with the moving front door 4, in order to prevent the moving front door 4 from being loosened or overtightened during the movement, a tool is used to penetrate the strip groove 5 and connect with the tool groove at the end of the adjusting bolt 11. After the connection, the tool is rotated to drive the adjusting bolt 11 to rotate. Since the adjusting bolt 11 is rotatably connected to the cross plate 6, the adjusting bolt 11 does not move during the rotation. At this time, the internal thread of the lifting plate 8 is driven to move upward or downward during the rotation of the adjusting bolt 11, and the lifting plate 8 During the movement, the rotating ear 9 drives the roller 10 to move up and down synchronously, so that the circumferential outer wall of the roller 10 contacts the inner wall of the sliding frame 2 and maintains an appropriate pressing force. This operation can avoid the situation that the upper roller 10 does not contact the inner wall of the sliding frame 2 in the sliding frame 2 due to production tolerance, which is an over-loose state and causes the moving front door 4 to shake during the movement. It can also avoid the situation that the upper and lower rollers 10 in the sliding frame 2 are excessively squeezed and contacted with the inner wall of the sliding frame 2 due to production tolerance, which is an over-tight state.

[0023] Therefore, the roller 10 can maintain appropriate pressure on the inner wall of the sliding frame 2 through the adjustable sliding assembly.

[0024] Please refer to Figure 3 The vertical sections of the lifting plate 8 and the lifting slot 7 are both in a "convex" shape. The lifting plate 8 and the rotating ear 9 located at the top are symmetrically arranged with the lifting plate 8 and the rotating ear 9 located at the bottom about the horizontal plane of the center of the fixed plate 1.

[0025] In this embodiment, the convex structural design of the lifting plate 8 and the lifting slot 7 can prevent the lifting plate 8 from separating from the lifting slot 7, and limit the maximum adjustment distance of the lifting plate 8, thereby avoiding over-pressure damage to the roller 10 caused by excessive adjustment.

[0026] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
