Multiple placement rack modules are fixedly installed at the bottom of the top plate, and a track is fixedly installed at the top of the top plate. An electric hoist is mounted on the track. This utility model allows the support frame at the desired placement location to be pulled out from the support plate via a sliding component. Then, the electric hoist lowers the injection mold onto the corresponding support frame, and then pushes the support frame to place the injection mold in the corresponding position. The injection mold is relatively heavy, and its weight presses down on the support frame, preventing the support frame from sliding under normal non-human external forces. The placement rack module is entirely composed of high-strength steel, capable of holding a large number of injection molds without the risk of tipping over or falling apart. Compared to traditional forklift placement, this method saves space and improves placement efficiency.

Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold placement rack. Background Technology

[0002] Injection molds are tools used to process and mold plastic products. They enable mass production by giving plastic specific shapes and precise dimensions, and are widely used in the automotive, home appliance, and electronics industries. Their core structure includes a moving mold, a fixed mold, and systems for gating, temperature control, and ejection. Molding processes are classified into six categories: injection molding, compression molding, extrusion, blow molding, vacuum forming, and high-density polystyrene molding.

[0003] In injection molding production, injection molds of various specifications and in large quantities require centralized storage for efficient management. Storage racks, as the core carriers, serve the functions of space integration and mold protection. Due to significant differences in mold weight and size, storage racks need to adopt a modular, layered design. The upper layer is suitable for small, precision molds, while the lower layer supports large mold frames. Adjustable supports can accommodate the storage needs of molds of different specifications, avoiding compression deformation or scratches caused by stacking.

[0004] Patent document CN215039683U discloses a multifunctional injection mold placement rack, including a rack body. Guide rails are fixedly connected to both sides of the inner cavity of the rack body. A placement plate is provided on one side of each guide rail opposite to the other. Pulleys are movably connected to the front and rear sides of both sides of the placement plate via rotating shafts. A sliding groove is provided on the side of the guide rail near the placement plate to cooperate with the pulleys. Limiting grooves are provided on the rear sides of both sides of the rack body. By configuring the rack body, guide rails, placement plate, pulleys, sliding grooves, limiting grooves, fixing mechanism, fixing groove, movable groove, limiting mechanism, first through hole, and second through hole in a coordinated manner, this invention solves the problem that existing multifunctional injection mold placement racks are inconvenient for fixing the placement plate. Furthermore, existing multifunctional injection mold placement racks are prone to shaking during use, leading to mold collisions and falls, causing mold damage and affecting usability.

[0005] As in the prior art of the aforementioned patent, during the process of placing molds on the aforementioned rack, since the molds are heavy, a lifting forklift is generally needed to place the molds into each rack layer.

[0026] 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.

[0027] Reference Figure 1-8 A mold placement rack includes a top plate 1 and support legs 2 fixedly installed at the bottom of the top plate 1. Multiple placement rack modules 5 are fixedly installed at the bottom of the top plate 1, and a track 3 is fixedly installed at the top of the top plate 1. An electric hoist 4 is mounted on the track 3. Each placement rack module 5 includes four frame bodies 6, with support plates 8 fixedly installed between the four frame bodies 6. Fixed plates 11 are mounted on the support plates 8, and sliding members 12 are slidably installed on two of the fixed plates 11. A load-bearing frame 13 composed of multiple steel rods is arranged between the two sliding members 12. The electric hoist 4 and the track 3 are existing technologies and will not be described in detail. The electric hoist 4 can operate on the track 3. The mold is moved between multiple placement rack modules 5 by sliding. First, the mold to be placed is lifted by the electric hoist crane 4. After being lifted to a certain height, the support frame 13 to be placed is pulled out from the support plate 8 by the sliding part 12. Then, the injection mold is placed down onto the corresponding support frame 13 by the electric hoist crane 4. Then, the support frame 13 is pushed to place the injection mold in the corresponding position. The injection mold is relatively heavy, and its weight presses on the support frame 13, so that the support frame 13 will not slide under the action of general non-human external force. The placement rack module 5 is made of high-strength steel and can hold a lot of injection molds without the risk of tipping over or falling apart.

[0028] It is important to note that placing the injection mold on the extended support frame 13 does not mean placing the entire weight of the injection mold directly on it. Instead, the injection mold comes into contact with the support frame 13, and part of the weight generated by the mold is supported by the support frame 13, while the other part is held in place by the pulling force provided by the crane above, preventing the support frame 13 from breaking due to excessive force. At this point, pushing the support frame 13, relying on the static friction generated between the support frame 13 and the mold, allows the support frame 13 to move the mold into the placement frame. When it moves to a certain position and the support frame 13 can fully support the injection mold, the crane above is released, and then the support frame 13 is pushed further in, thus completing the placement of the mold.

[0029] As a preferred embodiment, the inner wall of the fixed plate 11 is provided with a slide rail 15, the sliding member 12 is provided with a movable roller 14, the movable roller 14 is disposed inside the slide rail 15, one end of the fixed plate 11 is fixedly installed with a fixed roller 17, and the top end of the sliding member 12 is provided with a bent member 16, the bent member 16 overlapping the fixed roller 17; the sliding member 12 slides by the rolling of the movable roller 14 inside the slide rail 15, and the bent member 16 on the sliding member 12 can overlap the fixed roller 17, the fixed roller 17 can support the sliding member 12, so that the sliding member 12 can slide stably.

[0030] As a preferred technical solution of this embodiment, the slide rail 15 is provided with a limiting member 18 inside, and the limiting member 18 is disposed between the fixed roller 17 and the moving roller 14; the limiting member 18 can limit the fixed roller 17 inside the slide rail 15 to prevent the fixed roller 17 from sliding to too far out, which could easily cause derailment, tipping or the mold bending the support frame 13.

[0031] As a preferred technical solution in this embodiment, multiple first fasteners 7 are fixedly installed on the multiple frames 6, and the support plate 8 is fixedly connected to the frame 6 through the first fasteners 7. A reinforcing member 9 is provided between two frames 6 on one side. The reinforcing member 9 is X-shaped, and a second fastener 10 is fixedly installed between the reinforcing member 9 and the frame 6. The first fasteners 7 can realize the fixed installation of the support plate 8, and the second fasteners 10 can realize the installation of the reinforcing member 9. The reinforcing member 9 can increase the structural rigidity of the connection between the frames 6, and increase the load-bearing capacity and stability of the device.

[0032] As a preferred embodiment, two sliding strips 19 are slidably mounted on the support frame 13. Multiple through slots 20 are formed on the two sliding strips 19, and these slots 20 are slidably connected to the steel rods of the support frame 13. Two threaded holes 21 are formed at the top of each sliding strip 19, and bolts 22 are threaded into each of the two threaded holes 21. The two bolts 22 are located at both ends of the sliding strip 19. A placement box 23 is positioned between the two sliding strips 19, and two slots 24 are formed at the bottom of the placement box 23. The two slots 24 overlap the sliding strips 19, and the two bolts 22 are tightly pressed against the placement box 23. On the front and rear side walls; different injection molds have different lengths. The placement box 23 is designed according to the injection mold to be placed. Two slots 24 are opened at the bottom of the placement box 23. After the sliding bar 19 is moved to the position corresponding to the slot 24, the placement box 23 is placed. Then the position of the sliding bar 19 is positioned by the bolt 22. The bolt 22 is tightened downward and abuts against the steel rod of the support frame 13. The bolt 22 can limit the placement box 23 to prevent the placement box 23 from sliding back and forth. Placing the mold on the top of the placement box 23 can separate the mold from each steel rod of the support frame 13 and avoid the mold from directly contacting the steel rod and being unstable.

[0033] As a preferred technical solution in this embodiment, a rubber pad 25 is provided at the top of the placement box 23; the rubber pad 25 can protect the mold and prevent wear between the mold and the placement box 23.
