Description

TECHNICAL FIELD

[0001] The utility model relates to a die casting machine, in particular to an automatic retractable die repairing platform and a die casting machine containing the same. BACKGROUND

[0002] When a large die casting machine is repairing a die, there is no personnel working area inside the die casting machine. The current solution is to make a frame welded with square tubes, which is used as a temporary working area. However, this solution is not perfect. First, the platform is placed above the Golin column, although there are square tubes welded on the left and right sides to prevent the platform from moving left and right, there is no fixation in front and back, which poses a safety hazard. Second, the area above the Golin column is a die installation area, which means that the die bottom will be at the same height as the platform when the die is installed, making it difficult for the die repairing personnel to handle the bottom die. Finally, the platform directly contacts the Golin column, which may cause damage to the Golin column during use. SUMMARY

[0016] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0017] As Figure 1 shown, the automatic telescopic mold repairing platform in the embodiment comprises a computer controller, i.e. a programmable logic controller (not shown in the figure), and a base 1, two sides of the base 1 are provided with mutually parallel guide rails 3, the guide rails 3 are erected above the base 1 through four groups of support mechanisms, and a platform panel 2 is laid on the guide rails 3. Two reinforcing cross beams 33 are arranged between the two guide rails 3, so as to ensure the stability of the guide rails during movement and mold repairing.

[0018] The automatic telescopic mold repairing platform in the embodiment further comprises a driving mechanism for driving the guide rails 3 to move in a linear direction. The driving mechanism comprises a motor 8, a transmission belt wheel (not shown in the figure) and a transmission belt wheel protective cover 4 which cooperate with each other. The transmission belt wheel protective cover 4 is fixed at the front end of the base 1, a belt wheel driving wheel (not shown in the figure) is fixed on the rotating shaft of the motor 8, and the front end of the transmission belt wheel protective cover 4 is provided with a mounting shaft 41 for mounting a belt wheel driven wheel (not shown in the figure). The inner side of the guide rail 3 is provided with a guide rail driving wheel (not shown in the figure) which is matched with the transmission belt wheel. In the embodiment, the transmission belt wheel is a toothed belt, and the belt wheel driving wheel, the belt wheel driven wheel and the guide rail driving wheel are all toothed wheels which engage with the toothed belt. After the motor rotates, the belt wheel driving wheel drives the toothed belt to transmit power, and the toothed belt further drives the guide rail driving wheel to move, thereby driving the guide rail 3 which is mounted with the guide rail driving wheel to move linearly forward or backward.

[0019] Specifically, as Figure 2 shown, the guide rail 3 in the embodiment adopts a single-face channel steel, and the outer side thereof is provided with a containing groove 34. Each of the support mechanisms comprises a longitudinal support part 6 for bearing the weight of the platform panel 2. Each longitudinal support part 6 comprises a support shaft fixing seat 61 which is fixed on the base 1, the side wall of the support shaft fixing seat 61 is provided with a horizontally arranged support shaft 62, and the support shaft 62 is provided with a support shaft wheel 63 for supporting the platform panel 2. The support shaft wheel 63 and the support shaft 62 are connected through a first bearing 64, and the outer edge of the support shaft wheel 63 abuts against the inner surface of the top of the containing groove 34, so as to further support in the longitudinal direction. In the embodiment, there are four groups of longitudinal support parts, two by two as a group, and they are respectively located at the outer sides of the guide rails 3.

[0020] As Figure 3As shown, the support mechanism also includes a horizontal transmission part 7 for assisting the extension and retraction of the guide rail 3. The horizontal transmission part 7 includes a positioning shaft fixing seat 71 fixed to the base 1. The side of the positioning shaft fixing seat 71 is provided with upper and lower parallel pin plates 72. A positioning shaft wheel 73 is provided between the two pin plates 72. The pin plates 72 and the positioning shaft wheel 73 are inserted from top to bottom through the positioning shaft 74. The positioning shaft wheel 73 is connected to the positioning shaft 74 through a second bearing 75. The central axis of the positioning shaft wheel 73 is perpendicular to the horizontal plane, and the outer edge of the positioning shaft wheel 73 abuts against the vertical side wall of the accommodating groove 34.

[0021] At the same time, anti-slip baffles 31 are provided at the front and rear ends of the guide rail 3. The aforementioned support mechanism is located between the front and rear anti-slip baffles 31 on the same side. Anti-collision pads 32 are provided on the surface of the support mechanism opposite the anti-slip baffles 31. This prevents the guide rail from detaching from the support mechanism during extension and retraction, and cooperates with the anti-collision pads 32 to provide buffering and protection.

[0022] The automatic telescopic mold repair platform also includes a sensor switch 5 mounted on the base 1 and a contact block (not shown) mounted on the guide rail 3. A computer controller is connected to the motor 8 and the sensor switch 5 for signal transmission. The sensor switch 5 detects the position of the mold repair platform and transmits a signal to the computer controller when the platform reaches a specific position (preset position). Specifically, when the platform panel 2 moves along the guide rail 3 and approaches the limit position, the contact block mounted on the guide rail 3 contacts the sensor switch, which then sends an electrical signal to the computer controller. Upon receiving this signal, the computer controller controls the motor 8 to stop rotating, preventing the platform from exceeding the predetermined operating range.

[0023] When the platform needs to be retracted, that is, the motor rotates in the opposite direction, this is achieved through the control logic set within the computer controller. The computer controller will control the direction of the motor according to the preset program and the operator's instructions, thereby returning the platform to its original position.

[0024] This embodiment also discloses a die-casting machine, which includes a base 100. Unlike the prior art, this embodiment includes the aforementioned automatic telescopic die-repairing platform, which is located below the coring column (not shown). Specifically, the base 1 of the automatic telescopic die-repairing platform is fixedly connected to the base 100. During die-repairing, a computer controller controls a motor to drive the platform horizontally outward from below the coring column, forming a work area outside. When die-repairing is complete, the computer controller controls the motor to reverse and retract the platform.

[0025] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
