Description
Technical Field
[0001] This utility model relates to the field of injection molding production equipment, and in particular to a tray for injection molded parts. Background Technology
[0002] Injection molding pallets are tools used in the injection molding process for placing and transporting injection molded parts. They are widely used in the injection molding production processes of industries such as electronics, automobiles, home appliances, and medical devices. They can be used to place and transport various injection molded parts, and can also be used for the storage and transportation of goods, improving logistics efficiency.
[0003] Chinese Patent Publication No. CN220563161U discloses a stackable injection-molded pallet, including a pallet body and fixing components for stacking multiple pallet bodies. Several fixing components are evenly fixed to the left and right end faces of the pallet body. Each fixing component includes a connecting block and a connecting rod. The lower end face of the connecting block has a connecting rod placement groove. The connecting rod on the fixing component stacked on the lower pallet body is placed in the connecting rod placement groove on the fixing component stacked on the upper pallet body. This pallet, by incorporating fixing components that automatically connect and fix the injection-molded pallet during stacking, saves manual operation during stacking, is simple and convenient to use, and improves work efficiency.
[0004] However, the above technical solution has the following shortcomings: Although the pallet realizes the stacking function to efficiently transfer injection molded parts, when the fixing component fixes the pallet body, it only relies on the weight of the pallet body to retract the telescopic connecting rod to achieve the fixing effect. When the number of pallets stacked is large, and the vibration during transfer causes the spring to continuously extend and retract, the upper pallet may collapse. Utility Model Content
[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a pallet for injection molded parts. This not only improves the stability of pallets when stacked and ensures safety during transportation, but also allows for adjustment of the distance between the upper and lower pallets according to the height of the injection molded parts, thus expanding the applicability of the pallet.

The docking block has a positioning groove for the locking block to be embedded in.
[0007] Preferably, a guide rod is provided on the upright plate, a first spring is sleeved on the guide rod, and a second wedge is slidably connected to the guide rod.
[0008] Preferably, the card block is provided with three linearly distributed convex strips with triangular cross sections, and the positioning groove is provided with grooves that are compatible with the convex strips.

[0023] Example 1
[0024] like Figures 1-5 As shown in the figure, the tray for injection molded parts proposed in this embodiment includes a tray body 1 and a stabilizing mechanism; four support blocks 2 are provided on the tray body 1, and support components are provided on the support blocks 2.
[0025] The stabilizing mechanism is mounted on the support assembly and includes two horizontally arranged crossbeams 5, a pressure block 12 slidably disposed inside the crossbeams 5, two first wedges 13 symmetrically distributed on the pressure blocks 12, a second wedge 14 slidably connected to the first wedges 13, a connecting rod 15 disposed on the second wedges 14, a locking block 16 disposed on the connecting rod 15, a vertical plate 17 disposed inside the crossbeams 5, a first spring 18 disposed at both ends on the vertical plate 17 and the second wedge 14, a mounting block 11 disposed on the pallet body 1, and a docking block 29 disposed on the mounting block 11 and insertable into the crossbeams 5; the docking block 29 has a positioning groove for the locking block 16 to be embedded in.
[0026] A guide rod 19 is provided on the upright plate 17. A first spring 18 is sleeved on the guide rod 19. A second wedge block 14 is slidably connected to the guide rod 19. The guide rod 19 guides the extension and retraction of the first spring 18, preventing the first spring 18 from twisting and ensuring its service life. The locking block 16 is provided with three linearly distributed protrusions 20 with triangular cross-sections. The positioning groove has grooves that are adapted to the protrusions 20. The protrusions 20 increase the contact area to improve the tightness of the locking block 16.
[0027] In this embodiment, when it is necessary to connect the docking block 29 to the crossbeam 5 to complete the stacking operation of the pallet body 1, the pressure block 12 is moved first to make the inclined surfaces of the first wedge block 13 and the second wedge block 14 press against each other and slide relative to each other. Then, the second wedge block 14 drives the connecting rod 15 to move closer to each other while compressing the first spring 18. The connecting rod 15 drives the locking block 16 to move, and then the docking block 29 is inserted into the interior of the crossbeam 5. Then the pressure block 12 is released. Under the elastic force of the first spring 18, the second wedge block 14 drives the connecting rod 15 to move away from each other until the locking block 16 is embedded in the positioning groove of the docking block 29. At this time, the first spring 18 is still in a compressed state, thereby realizing the connection between the docking block 29 and the crossbeam 5. This not only greatly improves the stability of the pallet body 1 when stacking, but also makes the operation simple and convenient, avoiding the need to use multiple threaded fasteners, and has good practicality.
[0028] Example 2
[0029] like Figure 4 and Figure 5 As shown, in this embodiment, a tray for injection molded parts is provided. Compared with the first embodiment, in this embodiment, the pressure block 12 is provided with a driving component. The driving component includes a limiting ring 23 rotatably disposed inside the pressure block 12, a rotating shaft 22 coaxially disposed on the limiting ring 23, a threaded block 21 disposed on the rotating shaft 22 and threadedly connected to the cross frame 5, and a knob 24 disposed on the threaded block 21. The cross frame 5 is provided with a threaded groove, and the pressure block 12 is provided with four guide blocks 25 distributed in a ring array. The guide blocks 25 are slidably disposed inside the cross frame 5.
[0030] In this embodiment, by rotating the threaded block 21 with the knob 24, the threaded block 21 engages with the threaded groove, and at the same time, the rotating shaft 22 and the limiting ring 23 push the pressure block 12 to move, thereby controlling the connection between the docking block 29 and the cross frame 5. This prevents the first spring 18 from extending or contracting due to excessive pressure or vibration during transport, which could cause the locking block 16 to disengage from the positioning groove. Furthermore, the guide block 25 can guide the movement of the pressure block 12, ensuring that the mating surfaces of the first wedge block 13 and the second wedge block 14 do not become misaligned.
[0031] Example 3
[0032] like Figure 4 As shown, in this embodiment, a tray for injection molded parts is provided. Compared with the first embodiment, in this embodiment, the cross frame 5 is provided with a reinforcing component. The reinforcing component includes a pull rod 26 slidably connected to the cross frame 5, a reinforcing block 27 provided on the pull rod 26, and a second spring 28 with its two ends respectively provided on the cross frame 5 and the reinforcing block 27; the mating block 29 is provided with a circular groove for the reinforcing block 27 to be embedded.
[0033] In this embodiment, when the docking block 29 is embedded inside the crossbar 5, the reinforcing block 27 needs to be pulled in advance by the pull rod 26. At this time, the second spring 28 is compressed. After the docking block 29 is fully embedded, the pull rod 26 is released, and the reinforcing block 27 will move under the elastic force of the second spring 28 until the reinforcing block 27 is embedded in the circular groove, thereby further improving the stability of the upper and lower pallet bodies 1 when stacked.
[0034] Example 4
[0035] like Figure 1 and Figure 2 As shown, in this embodiment, a tray for injection molded parts is proposed. Compared with the first embodiment, in this embodiment, the support assembly includes a fixed cylinder 3 disposed on the support block 2, an adjusting column 4 disposed on the fixed cylinder 3 and having multiple through holes 10, a bolt 8 passing through the fixed cylinder 3 and the adjusting column 4, and a nut 9 threadedly connected to the bolt 8; a fixed block 6 is disposed on the crossbeam 5, the fixed block 6 is disposed on the adjusting column 4, an insert block 7 is disposed on the fixed block 6, and a rectangular groove that is compatible with the insert block 7 is disposed on the support block 2.
[0036] In this embodiment, before stacking, the rectangular slot on the upper support block 2 is aligned with the lower insert block 7 and inserted to achieve pre-positioning of the stack, which facilitates the connection of the stabilizing mechanism and improves the stability of the connection. At the same time, the distance between the upper and lower tray bodies 1 can be adjusted according to the height of the injection molded part to minimize the stacking height while ensuring that the injection molded part can be placed. When adjusting the height, the distance of the adjusting column 4 extending out of the fixed cylinder 3 can be changed, and the nut 9 can be screwed on in conjunction with the bolt 8 through the through hole 10 to achieve the adjustment.
[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
