Description

Technical Field

[0001] This utility model relates to a production device, and more specifically, to a mold shifting device for a reciprocating traffic cone preparation machine. Background Technology

[0002] The traffic cone injection molding production unit is an automated industrial equipment specifically designed for the mass production of plastic traffic cones. Its core process is based on injection molding technology to process thermoplastic raw materials such as polyethylene into standardized cone-shaped traffic sign products. The unit mainly consists of three systems: the injection molding machine as the core power source, the mold system for shaping the geometry of the traffic cone, and the automated control components to realize the production process. In the traditional production process, after the injection molding of a traffic cone is completed, the entire system must enter a waiting state until the product in the mold cools and solidifies and the mold opening operation is completed before the next production cycle can start. During this period, the temperature of the nozzle of the injection molding machine will drop rapidly from the working temperature. When the system restarts, the operator must first use the cleaning procedure to remove the waste material that has cooled and solidified in the nozzle. This not only wastes raw materials but also adds extra ineffective working time to each production cycle, seriously restricting the output capacity. Therefore, a reciprocating traffic cone manufacturing machine mold shifting device is needed. This device can produce efficiently and has a high material utilization rate.

[0003] For the reasons mentioned above, how to achieve efficient production and high material utilization is precisely the issue addressed in this application. Utility Model Content

[0004] To address the shortcomings of existing technologies, a mold shifting device for a reciprocating traffic cone manufacturing machine is provided. This device can improve the working efficiency of operators and is suitable for the manufacturing of large-sized traffic cones.

[0005] To achieve the above objectives, the following technical solution is provided: a reciprocating traffic cone manufacturing machine mold shifting device, comprising a base and a mounting base, wherein a sliding mechanism is provided between the mounting base and the base, and the base has a product removal station, a mold opening station and an injection molding station, wherein the mold opening station is located between the injection molding station and the product removal station; a power mechanism is drivenly connected to the mounting base to enable the mounting base to move between the product removal station, the mold opening station and the injection molding station, characterized in that a worktable is movably provided on the base, the upper end surface of the worktable protrudes to the upper side of the base, the worktable is located outside the mounting base, and the worktable is fixedly connected to the mounting base.

[0006] Furthermore, the worktable is a housing, and the worktable is fastened to the base.

[0007] Furthermore, a limiting structure is provided between the worktable and the base. The limiting structure is used to limit the movement distance of the mounting seat on the base. The limiting distance of the mounting seat by the limiting structure corresponds to the interval between the product removal station and the injection molding station.

[0008] Furthermore, a receiving opening is provided on the upper surface of the worktable, with the opening facing the mounting base, and the receiving opening is used to receive the mold.

[0009] Furthermore, it also includes a movable frame, with sliding mechanisms provided between the movable frame and the base, and between the mounting base and the movable frame; the power mechanism includes a main power mechanism and a supporting power mechanism, the main power mechanism being disposed between the base and the movable frame to realize the translation of the movable frame relative to the base; the supporting power mechanism being disposed between the mounting bases to realize the translation of the mounting base on the movable frame.

[0010] Furthermore, the main power mechanism includes a rack disposed on the lower side of the base, the rack being disposed along the length direction of the base, a motor being disposed on the moving frame, and a gear being disposed on the power output shaft of the motor, the gear meshing with the rack.

[0011] Furthermore, the width of the workbench is smaller than the width of the base, and the workbench is located at the middle position in the width direction of the base, thereby forming a step between the workbench and the base.

[0012] In summary, the above technical solution offers the following advantages: By setting a worktable on the base, protruding above the base, a raised standing position is created outside the mold, facilitating operator work and effectively improving efficiency. The worktable allows operators to easily adapt to the needs of preparing traffic cones from tall molds, making it easier to remove the product from the mold. The worktable is connected to the mounting base and can move with it. When problems arise in other parts of the traffic cone preparation machine or other tasks require additional work, the worktable can be used to assist in these tasks. Attached Figure Description

[0016] Reference Figure 1-2As shown, a reciprocating traffic cone manufacturing machine mold shifting device includes a base 1 and a mounting base. A sliding mechanism is provided between the mounting base and the base 1. The base 1 has a product removal station, a mold opening station, and an injection molding station. The mold opening station is located between the injection molding station and the product removal station. A power mechanism is drivenly connected to the mounting base, causing the mounting base to move between the product removal station, the mold opening station, and the injection molding station. A worktable 2 is movably provided on the base 1. The upper end surface of the worktable 2 protrudes to the upper side of the base 1. The worktable 2 is located outside the mounting base and is fixedly connected to the mounting base.

[0017] This invention features two relatively independent mounting bases and two sets of molds 3. While one mold 3 is performing injection molding at the injection station, the other mold 3 can simultaneously open at the mold opening station and perform subsequent processing at the product removal station. This significantly shortens the waiting time between production cycles. The time originally used for waiting for the molded part to cool can be used for production operations with the other mold 3. During this period, the temperature of the injection head 9 will not drop rapidly from its operating temperature. Operators do not need to clean the injection head 9 or simply wipe away spilled material before the next production run, thus maximizing material utilization and improving overall production efficiency.

[0018] In the operation process, a power mechanism drives the mounting seat to slide to the injection station, so that the mold 3 located in the injection area can complete the injection of molten plastic; the other mounting seat is away from the injection station and is located at the product removal station or mold opening station, so that the worker can safely remove the product and prepare for the next cycle. After the injection is completed, the mold 3 with the product removed enters the injection station, thus realizing the cycle operation.

[0019] The power mechanism can employ a guide rail slider system or a hydraulic telescopic system, allowing for precise positioning of the mounting base through movement. This ensures the injection molding components remain stationary, reducing the impact of vibration on injection accuracy. The dual-mold, three-stage alternating operation eliminates the waiting time of traditional single-station injection molding. The injection molding machine does not require frequent start-stop cycles, maintaining a stable operating temperature for near-continuous injection production, thus improving efficiency. Furthermore, the physical separation of the injection and mold opening areas prevents operators from contacting high-temperature or high-pressure injection zones, reducing the risk of workplace injuries.

[0020] This utility model uses a power mechanism to drive the mounting base to allow the two sets of mold systems to work alternately, thereby eliminating the waiting time of traditional single-station operation. It avoids the problem that the temperature of the nozzle part drops rapidly from the working temperature due to the long waiting time during production, and that the operator must perform a material cleaning procedure before production can resume. This results in high-efficiency production and high material utilization.

[0021] The core function of this device is to enable the automated continuous production of traffic cones by using a precision translation system to move the mounting base and the mold 3 on it precisely and reciprocally between three key stations.

[0022] The base 1 forms a fixed foundation, the mounting base forms a moving platform for mounting the mold 3, the sliding mechanism forms a linear motion path, and the worktable 2 forms a shell and functional platform. The power mechanism pushes the mounting base, causing it to slide horizontally along the sliding mechanism on the base 1. Since the mold 3 is fixed to the mounting base, it moves between the three workstations. The worktable 2, fixedly connected to the mounting base, also moves between these three positions. The worktable 2 acts as a shell, fitting snugly onto the base 1. It encloses the internal sliding mechanism and transmission components, preventing dust and oil intrusion and protecting operator safety. The protruding upper surface of the worktable 2 can serve as an operating platform for the operator to step on. Furthermore, a receiving opening 11 is provided on the side of the worktable 2 facing the mold 3, opening towards the mold 3 for precise positioning and accommodating the mold 3, ensuring its stability during movement. The width of the worktable 2 is smaller than the width of the base 1, forming a step between them. Before the operator steps onto the workbench 2, the height of the base 1 can be used to facilitate the operator's smooth entry onto the workbench 2.

[0023] The limiting structure limits the movement distance of the mounting base on the base 1. The limiting distance corresponds to the interval between the product removal station and the injection molding station, ensuring that the mounting base and mold 3 can accurately stop at the three predetermined stations to prevent deviations that could lead to misalignment of the injection port, failure of the mold opening mechanism, or failure to remove the part. The limiting shell 4 is fixed to the mounting base and moves with it. The wall of the limiting shell 4 is provided with a limiting opening 5, which is set along the moving direction of the mounting base. The length of the limiting opening 5 corresponds to the interval between the product removal station and the injection molding station. The limiting opening 5 is an elongated hole machined on the limiting shell 4, and the limiting rod 10 is fixed to the base 1, with its end of the limiting body inserted into the limiting opening 5. When the mounting base moves, the limiting shell 4 moves accordingly, and the limiting opening 5 slides relative to the stationary limiting rod 10.

[0024] The length of the limiting port 5 determines the maximum range of movement of the mounting base. When the limiting body moves to one end of the limiting port 5, it cannot move further, thus mechanically limiting the travel of the mounting base. The length of the limiting port 5 is precisely designed to be equal to the interval between the product removal station and the injection molding station, thereby ensuring that the range of movement exactly covers all three stations.

[0025] An inner shell 6 is provided inside the limiting shell 4. The inner shell 6 is fixedly connected to the mounting base. The inner shell 6 enhances the structural strength of the limiting shell 4, prevents it from deforming under stress, and ensures long-term stability of the limiting accuracy.

[0026] The dual-power mechanism and the movable frame 8 are used to solve the stability and power arrangement problems of long-stroke movement. Sliding mechanisms are provided between the movable frame 8 and the base 1, and between the mounting base and the movable frame 8. The power mechanism includes a main power mechanism and a supporting power mechanism 7. A single high-power motor and a long rack may have problems such as insufficient rigidity, large vibration, and high cost. It can be decomposed into two movements: the movement of the movable frame 8 relative to the base 1 and the movement of the mounting base relative to the movable frame 8.

[0027] The main power mechanism is set between the base 1 and the moving frame 8. The main power mechanism is equipped with a motor. The motor power output shaft drives the gear, which meshes with the rack fixed on the lower side of the base 1. The rack is set along the length direction of the base 1, which is equivalent to a gear rack pair. When the motor rotates, the gear moves along the fixed rack, thereby driving the entire moving frame 8 to make a long stroke coarse movement along the length direction of the base 1.

[0028] The supporting power mechanism 7 is located between the mounting bases. The principle of the supporting power mechanism 7 is similar to that of the main power mechanism, which pushes the mounting base to make short-stroke fine movements on the moving frame 8.

[0029] By dividing the total travel distance into two parts, two smaller motors can be used instead of one high-power motor, reducing costs and energy consumption. The moving frame 8 acts as an intermediate support, providing additional guidance and support points for the mounting base, reducing cantilever effects, making long-stroke movements smoother, and preventing mold 3 from shaking. The two power mechanisms can work together to achieve more complex motion patterns and optimize production rhythm.

[0030] The entire process is reciprocating, realizing continuous and automated production of traffic cones. The sliding mechanism ensures smooth and low-friction movement, the limiting structure ensures precise positioning, the power mechanism provides reliable movement, and the worktable 2 provides protection and support, together forming an efficient and reliable mold 3 shifting device.
