Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a movable tray for mold processing workpieces. Background Art

[0002] Molds refer to various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods.

[0003] During the mold production and processing, the mold needs to go through multiple processing steps. During this process, a pallet is needed to transfer the mold between each process. The surface of a traditional pallet does not have a limiting function. When the pallet is transported by a forklift, the mold placed on the pallet is prone to offset due to inertia, which can easily cause the mold to slip and be damaged. Based on this, a mobile pallet for mold processing workpieces is provided. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figures 1 to 4In an embodiment of the utility model, a mobile pallet for processing mold workpieces includes a pallet body 1 composed of a chassis 101 and a support box 102, the support box 102 is located on the top of the chassis 101, and a protection component 2 is provided at the bottom of the chassis 101 and inside the support box 102, and the protection component 2 is used to limit the mold placed on the top of the support box 102 when the pallet body 1 is forked by a forklift;

[0033] The protection assembly 2 includes a lifting unit, a limiting unit, and a decompression unit. The lifting unit is used to be forced to move upward when the forklift transports the pallet body 1, and is used to provide a lifting force for the limiting unit. The limiting unit moves upward to limit the mold placed on the top of the support box 102. The decompression unit is used to release the extrusion of the limiting unit on the mold in contact with the mold.

[0034] The lifting unit includes a bottom plate 201, a connecting column 202, and a lifting plate 203;

[0035] The bottom of the chassis 101 is formed with a fork transport groove 104 for inserting the fork arm of the forklift, the bottom plate 201 is limitedly slidably connected in the fork transport groove 104, the connecting column 202 is fixed to the top of the bottom plate 201, and the lifting plate 203 is vertically slidably connected to the inner side of the support box 102;

[0036] The connecting column 202 passes through the top of the chassis 101 to the inside of the support box 102 and is fixedly connected to the bottom of the lifting plate 203;

[0037] The bottom plate 201 is lifted by inserting the fork arm of the forklift into the fork transport groove 104 and lifting it, so as to realize the upward movement operation of the lifting plate 203;

[0038] The limiting unit includes a fixed cylinder 204, a limiting round block 206, a contraction spring 207, a telescopic column 208, and a limiting column 209;

[0039] The fixed column 204 is fixed to the top of the lifting plate 203, the limiting round block 206 is arranged inside the fixed column 204, the contraction spring 207 is bonded and fixed to the top of the limiting round block 206, and the telescopic column 208 is bonded and fixed to the top of the contraction spring 207;

[0040] The top of the support box 102 is provided with a T-shaped hole slot 103 penetrating into the inner cavity of the support box 102, the limiting column 209 is received inside the T-shaped hole slot 103, and the telescopic column 208 passes through the top of the fixed column 204 and the bottom of the T-shaped hole slot 103 from the inside of the fixed column 204 in sequence and is fixedly connected to the limiting column 209;

[0041] When the lifting plate 203 moves upward, it pushes the limiting column 209 to protrude to the top of the support box 102, so as to limit the periphery of the mold placed on the top of the support box 102;

[0042] The decompression unit includes a shrinkage groove 205, a deformation groove 210, and an arc-shaped spring piece 211;

[0043] The contraction groove 205 is formed at the bottom of the inner wall of the fixed cylinder 204, and the limiting round block 206 is limitedly slidably connected to the inner side of the contraction groove 205;

[0044] The deformation groove 210 is symmetrically arranged outside the fixed cylinder 204 and intersects with the contraction groove 205. The top of the arc-shaped spring piece 211 is fixed to the top of the inner wall of the deformation groove 210. The arc surface of the arc-shaped spring piece 211 protrudes to the inner side of the contraction groove 205 and fits with the bottom of the limiting round block 206, so as to limit the height of the limiting round block 206.

[0045] When the limiting column 209 moves upward and contacts the mold, the contraction spring 207 is contracted by force and gives the limiting circle 206 a downward push. The limiting circle 206 squeezes the arc-shaped spring piece 211 to deform and slide down to the bottom of the contraction groove 205, which is used to release the elastic force of the contraction spring 207, thereby releasing the extrusion of the limiting column 209 on the mold.

[0046] In this embodiment, when the transfer tray is used to transfer the mold, the mold can be transferred and placed on the top of the support box 102 through an external lifting device (it should be noted that at this time, the limiting column 209 is completely retracted inside the T-shaped hole groove 103 and does not contact the mold);

[0047] Afterwards, the pallet body 1 is forklifted by a forklift. When the forklift fork arm is inserted into the fork transport groove 104 (it should be noted that the fork arm is located at the bottom of the bottom plate 201 at this time), the forklift fork arm moves upward to lift the pallet body 1 as a whole to make it off the ground. During the process, the fork arm can lift the bottom plate 201 upward, and the bottom plate 201 pushes the lifting plate 203 and the limiting unit upward as a whole through the connecting column 202. The limiting column 209 that does not contact the mold protrudes to the top of the support box 102, thereby realizing the limiting protection around the mold. In the later transfer process, it can effectively prevent the mold from sliding and deviating due to inertia;

[0048] The limiting column 209 in contact with the mold is limited by the mold and cannot move upward. At this time, the corresponding contraction spring 207 is squeezed and contracted. The contraction spring 207 gives a downward thrust to the limiting circle 206, and this thrust will become larger and larger. The limiting circle 206 will squeeze the arc spring piece 211 under the action of this thrust, and finally the arc spring piece 211 will deform and contract into the deformation groove 210. At this time, the limiting circle 206 will move down to the bottom of the contraction groove 205 under the action of the thrust, that is, the elastic force of the contraction spring 207 is released at this time, thereby relieving the extrusion on the mold and avoiding extrusion scratches on the mold.

[0049] Please refer to Figures 1 to 4There are multiple and equal numbers of limit units and T-shaped hole slots 103, and the multiple limit units and T-shaped hole slots 103 are distributed in a matrix. The inner diameter of the large-diameter hole at the top of the T-shaped hole slot 103 matches the outer diameter of the limit column 209, and the inner diameter of the small-diameter hole at the bottom of the T-shaped hole slot 103 matches the outer diameter of the telescopic column 208.

[0050] In this embodiment: by setting a plurality of limiting units, all-round limiting protection for molds of different shapes can be achieved;

[0051] In addition, the T-shaped hole groove 103 can be used to limit the downward movement of the limiting column 209. When the forklift places the pallet body 1 as a whole on the ground, the protection component 2 will automatically move down and reset under its own gravity, and the limiting column 209 will be stored in the T-shaped hole groove 103. During this process, the limiting column 209 can pull the limiting circle 206 through the contraction spring 207, so that the limiting circle 206 that slides down to the bottom of the contraction groove 205 squeezes the arc-shaped spring piece 211 to deform, and finally resets to the top position of the contraction groove 205, which is convenient for secondary use in the later stage.

[0052] Please refer to Figures 1 to 4 The chassis 101, the support box 102, the bottom plate 201, the connecting column 202, the lifting plate 203, the fixed column 204, the telescopic column 208, and the limiting column 209 are all made of metal material, and the outer side of the limiting column 209 and the top of the support box 102 are covered with a rubber layer, and the rubber layer on the top of the support box 102 is formed with a through hole for the limiting column 209 to pass through.

[0053] In this embodiment: each component made of metal material can ensure strong support and anti-deformation force, thereby ensuring the safe transfer of the mold;

[0054] The rubber layer is provided to avoid a hard collision with the mold.

[0055] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
