Description

Technical Field

[0001] This utility model relates to the field of plastic pallet processing technology, and in particular to a double-sided plastic pallet injection molding die. Background Technology

[0002] Plastic pallets are flat pallets made of plastic that are widely used in logistics, warehousing, and transportation. Compared to traditional wooden or metal pallets, plastic pallets have many advantages, such as being lightweight, corrosion-resistant, moisture-resistant, and less prone to deformation. They are suitable for various industrial and commercial activities.

[0003] An existing application (application number 202120273125.7) discloses a double-sided plastic pallet injection molding mold, comprising a mold body, an injection tube on the upper side of the mold body, multiple inner cores fixedly connected to the inner side of the mold body, a push plate slidably connected inside the mold body, multiple openings on the side wall of the push plate, and multiple inner cores located inside the multiple openings respectively. Two push rods are fixedly connected to the side wall of the push plate. The push plate can push the molded plastic pallet out of the mold body for easy removal by workers. However, after the plastic pallets are produced, they need to be stacked one by one and then transported away by forklift. This method requires workers to manually stack the plastic pallets after production, which not only consumes manpower but also makes it easy for the stack to be stacked crookedly during forklift transportation, causing the stack to collapse and injure workers.

[0004] To address the above issues, we propose a double-sided plastic pallet injection molding die. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing a double-sided plastic pallet injection molding mold.

[0007] In the above-mentioned double-sided plastic pallet injection molding mold, the lower end of the support block in each support mechanism is arc-shaped.

[0008] In the above-mentioned double-sided plastic pallet injection molding mold, a plastic pallet body is provided above the support frame, and an electric lifting platform is provided on the platform.

[0009] In the above-mentioned double-sided plastic pallet injection molding mold, two limiting strips are fixedly connected to the platform, an electric telescopic rod is fixedly connected to the base, and a push rod is fixedly connected to the telescopic end of the electric telescopic rod.

[0010] In the above-mentioned double-sided plastic pallet injection molding mold, an electric slide rail is fixedly connected to the base, and a handling robotic arm is provided on the electric slide rail.

[0011] In the above-mentioned double-sided plastic pallet injection molding mold, the base is provided with a telescopic cylinder, the telescopic end of the telescopic cylinder is fixedly connected to a movable mold, and the base is provided with a fixed mold.

[0012] Compared with existing technologies, the advantages of this double-sided plastic pallet injection molding mold are: This invention uses a robotic arm to place the processed plastic pallet onto a platform, pushes it under a support frame with a push rod, and then raises an electric lifting platform to stack the plastic pallet on each support mechanism at a neat stacking angle, preventing the stacked plastic pallets from collapsing when transported by forklifts.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 A double-sided plastic pallet injection molding mold includes a base 1, a platform 2 fixedly connected to the upper end of the base 1, a support frame 3 fixedly connected to the upper end of the platform 2, four support mechanisms on the support frame 3, each support mechanism including a U-shaped block 4, the U-shaped block 4 being fixedly connected to the support frame 3, a rotating rod 5 rotatably connected to the U-shaped block 4, a support block 6 fixedly connected to the rotating rod 5, a first opening 7 on the rotating rod 5, a fixed rod 8 fixedly connected to the U-shaped block 4, a second opening 9 on the fixed rod 8, a tension spring 10 between the fixed rod 8 and the rotating rod 5, one end of the tension spring 10 being fixed to the first opening 7 and the other end being fixed to the second opening 9, and a stop bar 11 fixedly connected to the rotating rod 5. The tension spring 10 pulls the rotating rod 5, causing the stop bar 11 to abut against the fixed rod 8.

[0017] The lower end of the support block 6 in each support mechanism is arc-shaped. A plastic pallet body 16 is provided above the support frame 3. The support block 6 in each support mechanism is inserted into the middle gap of the plastic pallet body 16, and the upper end of the support block 6 in each support mechanism contacts the upper inner wall of the plastic pallet body 16 to support the plastic pallet body 16.

[0018] Platform 2 is equipped with an electric lifting platform 13. Two limiting strips 12 are fixedly connected to platform 2, and an electric telescopic rod 14 is fixedly connected to base 1. A push rod 15 is fixedly connected to the telescopic end of the electric telescopic rod 14. When the new plastic pallet body 16 is located on platform 2, the electric telescopic rod 14 drives the push rod 15 to push the new plastic pallet body 16 to the lower part of the support frame 3 and the upper part of the electric lifting platform 13 through the limiting of the two limiting strips 12. The electric lifting platform 13 rises, causing the new plastic pallet body 16 to rise. The upper part of the new plastic pallet body 16 contacts the lower part of the upper plastic pallet body 16 and lifts the upper plastic pallet body 16 upward. During the upward process, the lower inner wall of the upper plastic pallet body 16 contacts the arc of the lower end of the support block 6 in each support mechanism and opens each support block 6. After rising to a certain extent, when the gap in the middle of the new plastic pallet body 16 reaches the position of each support block 6, each support block 6 returns to its original position through the corresponding tension spring 10, thereby supporting the new plastic pallet body 16.

[0019] An electric slide rail 20 is fixedly connected to the base 1. A handling robotic arm 21 is mounted on the electric slide rail 20. The handling robotic arm 21 is equipped with mechanical grippers. The handling robotic arm 21 is existing technology and will not be described in detail here. A telescopic cylinder 17 is mounted on the base 1. A moving mold 18 is fixedly connected to the telescopic end of the telescopic cylinder 17. A fixed mold 19 is mounted on the base 1. The telescopic cylinder 17 drives the moving mold 18 and the fixed mold 19 to close for injection molding and cooling processing. A push plate mechanism is provided inside the fixed mold 19. After processing, the cooled and processed plastic pallet body 16 is pushed out halfway from the fixed mold 19. The handling robotic arm 21 grabs the processed plastic pallet body 16. After grabbing, the push plate mechanism pushes the processed plastic pallet body 16 out completely. The handling robotic arm 21 then places the processed plastic pallet body 16 on the platform 2 and pushes it under the support frame 3 by the push rod 15, thereby stacking it on the support mechanisms.

[0020] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
