Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a motorized template sliding foot mechanism for injection molding. Background Art

[0002] An injection molding machine is a machine for plastic injection molding. Its clamping mechanism is used to open and close the molding mold by quickly and smoothly manipulating the movable platen. At the same time, the pull rod guides the movable platen. The height adjustment of the sliding foot mechanism on the bottom side of the movable platen can ensure that there is sufficient fitting clearance between the movable platen and the pull rod, ensuring that the pull rod plays a better guiding role in the process of opening and closing the mold.

[0003] The sliding feet of the movable template are usually fixed on the bottom feet of the second plate, and the outer side of the sliding feet contacts the guide rail. At the same time, the lower inclined irons at both ends are installed on both sides of the upper inclined iron, and the height of the two plates is adjusted by adjusting bolts and screws to ensure that there is enough clearance between the movable template hole and the pull rod. At present, in order to improve the installation efficiency of the upper inclined iron, the mass of the upper inclined iron will be increased, resulting in inconvenience in installation and maintenance. In addition, the posts usually need to contact the slide rails. When the moving distance of the movable template is long, a split guide rail will be installed, which will cause collision when the inclined iron moves.

[0004] According to the Chinese patent publication number CN117817954A "A Sliding Foot Mechanism for a Template of an Injection Molding Machine", it mainly describes that through a cleaning unit, when the movable template moves into the mold closing and parting, it can drive the roller to roll on the slide rail. Through the reaction force of the tensioning spring, the force of the roller on the slide rail can be increased, which can be beneficial to the output of the roller rolling power. When the roller rotates, it can drive the rotating shaft to rotate on the inner wall of the fixed frame, thereby driving the roller to rotate. The roller can drive the rubber strip to rotate, thereby cleaning the metal debris generated by the friction on the slide rail. By setting a screw The spirally arranged rubber strips can transport the cleaned metal debris to one side of the slide rail, thereby avoiding a large amount of metal debris from accumulating on the slide rail, preventing the metal debris from causing further wear and scratches on the slide plate and the slide rail, reducing the friction between the slide foot and the slide rail, and maintaining smooth movement between the slide plate and the slide rail, thereby enabling the movable template to move smoothly, enabling the injection molding machine to quickly complete the mold closing and mold opening operations during the production process, and improving the production efficiency of the injection molding machine. During the movement of the movable template, the slide foot touches the gap where the guide rail is connected, causing a collision, resulting in unstable movement of the movable template.

[0005] Therefore, an injection molding movable template sliding foot mechanism is proposed to solve the problem that the sliding foot may collide with the gap between the guide rails during the movement of the movable template, resulting in unstable movement of the movable template. Utility Model Content

[0006] The technical problem to be solved by the present invention is that during the movement of the movable template, the sliding foot touches the gap where the guide rails are connected, which causes a collision and leads to unstable movement of the movable template. Therefore, an injection molding movable template sliding foot mechanism is proposed.

[0007] The technical solution adopted by the utility model to solve the technical problem is: an injection molding mobile template sliding foot mechanism, including a movable template body and a guide rail, positioning holes are evenly opened on the bottom side of the movable template body, and an adjusting screw is threadedly connected to the positioning hole, and an upper inclined plate is sleeved on the adjusting screw. The upper inclined plate is U-shaped, and the upper part of the upper inclined plate contacts a limiting block, and the bottom side of the limiting block contacts a lower inclined plate, and a graphite copper slider is fixedly connected to the bottom end of the lower inclined plate, and a first groove is opened on the lower inclined plate, and arc angles are opened on both sides of the lower inclined plate close to the movable template body, and the arc angles are in contact with the guide rail.

[0008] As an optimal technical solution of the present invention, a guide groove is provided on the lower inclined plate, and the lower inclined plate is fixedly connected to a vertical rod in the guide groove. A protrusion is sleeved on the vertical rod, and the protrusion is fixedly connected to both sides of the limit block. By arranging the vertical rod and the protrusion in the guide groove, the upper inclined iron can be facilitated to move up and down.

[0009] As an optimal technical solution of the present invention, the lower inclined plate is fixedly connected to a support frame near the arc corner, and a pressure wheel is rotatably connected to the support frame. The pressure wheel contacts the guide rail. By setting the support frame and the pressure wheel, the contact surface between the inclined iron and the guide rail is increased, thereby improving stability.

[0010] As a preferred technical solution of the present invention, a brush is fixedly connected to one side of the support frame, and the brush contacts the guide rail. By providing the brush, the contact surface between the guide rail and the inclined iron can be cleaned.

[0011] As an optimal technical solution of the present invention, a buffer spring is sleeved on the adjusting screw, and the two ends of the buffer spring respectively contact the dynamic template body and the upper inclined plate. By setting the buffer spring, a buffer spacing is provided to increase the stability of the gap between the inclined iron and the guide rail.

[0012] As an optimal technical solution of the present invention, a distance sensor is fixedly connected to the upper inclined plate, and the distance sensor corresponds to the bottom side of the movable template body. By setting the distance sensor to the distance between the inclined iron and the movable template, the stability of the movable template during movement is increased.

[0013] The utility model has the following advantages: by arranging an arc angle on the lower inclined iron, the arc angle can provide a buffer when encountering the gap between the guide rails, and at the same time, the guide rails are cleaned with a brush and the pressure wheel is used to increase the contact surface of the inclined iron, which can greatly improve the stability of the sliding foot movement. At the same time, by arranging a limit block that can move up and down in conjunction with the vertical rod and the protrusion, the adaptability of the connection can be improved during the process of staggered placement and fixation of the upper and lower inclined irons.

A first groove 8 is provided on the lower inclined plate 6. Arc angles 9 are provided on both sides of the lower inclined plate 6 close to the movable template body 1. The arc angles 9 are in contact with the guide rails. When the guide rails are of a split structure, when the movable template body 1 moves to the gap between the contact guide rails, collision and shaking will occur, affecting the movement of the movable template. Therefore, the arc angles 9 can increase the stability of the sliding foot during movement.

[0020] Among them, protrusions 12 are fixedly connected on both sides of the limit block 5, the protrusions 12 are sleeved on the vertical rod 11, the vertical rod 11 is fixedly connected to the guide groove 10 of the lower inclined plate 6, and the guide groove 10 is located on the lower inclined plate 6. By setting the guide groove 10, cooperating with the vertical rod 11 and the protrusion 12, the limit block 5 can be moved up and down, thereby facilitating the contact between the inclined surfaces of the upper inclined plate 4 and the lower inclined plate 6, and facilitating the limiting installation of the other adjusting screw 3.

By providing the brush 15 , the contact surface between the guide rail and the inclined iron can be cleaned when the inclined iron moves, thereby improving the stability of the inclined iron movement.

[0023] Among them, the upper inclined plate 4 and the movable template body 1 respectively contact the two ends of the buffer spring 16, and the buffer spring 16 is sleeved on the adjusting screw 3.
