Description

Technical Field

[0001] This invention relates to the field of mold logistics and transportation technology, and in particular to a protective storage box for high-precision mold logistics and transportation. Background Technology

[0002] A mold is a tool that changes the shape of an object by shaping the physical state of the material. The most common type of mold is a stamping mold. With the development of the logistics industry, molds are usually sent to customers via logistics. To avoid damage to some high-precision molds during logistics transportation, protective storage boxes are needed to store them.

[0003] Existing high-precision mold logistics and transportation storage boxes, such as the logistics transportation box mentioned in patent number CN201811438770.9, include an outer box and an inner box. The bottom plate inside the outer box has grooves evenly distributed in the left and right directions, and ice blocks are placed in the grooves. A support spring is provided at the bottom of the inner box, and the support spring is in contact with the ice blocks at the bottom of the outer box. The upper end of the inner box has spherical grooves evenly distributed around its circumference. An inner box cover is provided on the top of the inner box. The inner box cover is connected to the inner box by a rubber connecting rod provided on the lower surface of the inner box cover corresponding to the position of the spherical groove on the inner box. The lower end of the connecting rod has a spherical structure. A sponge layer is provided between the inner box and the inner box cover. The top of the outer box has an outer box cover. The lower outer edge of the outer box cover has corn-shaped teeth evenly distributed around its circumference. The upper outer edge of the outer box has corn-shaped grooves corresponding to the corn-shaped teeth. The top of the inner box cover has grooves evenly distributed in the left and right directions, and ice blocks are placed in the grooves. A spring is provided on the top of the outer box cover to press the ice blocks.

[0004] However, the current traditional storage boxes used for high-precision mold logistics transportation are not very effective in fixing and protecting high-precision molds. They usually use wooden wedges to embed in the gap between the high-precision mold and the storage box to fix the mold. When the storage box is subjected to violent transportation, the high-precision mold is very easy to be affected by inertia and collide back and forth inside the storage box, causing damage to the high-precision mold. Summary of the Invention

[0005] In view of this, the present invention provides a protective storage box for high-precision mold logistics transportation. When the slider at the bottom end of the vertical clamping rod is inserted into the bottom connecting hole opened in the bottom clamping plate, the two vertical clamping rods are moved outward, increasing the distance between the two vertical clamping rods. The slider is affected by the inclined end face of the bottom side of the bottom connecting hole, which drives the top clamping plate to move downward, reducing the distance between the top clamping plate and the bottom clamping plate. This allows the elastic bottom rubber sheet on the top side of the bottom clamping plate and the elastic top rubber sheet on the bottom side of the top clamping plate to tightly clamp the upper and lower sides of the high-precision mold, thereby achieving the effect of clamping and fixing the high-precision mold and ensuring the stability of the high-precision mold logistics transportation status.

[0006] This invention provides a protective storage box for high-precision mold logistics transportation, specifically comprising: a logistics transportation box; a bottom clamp plate installed inside the bottom of the logistics transportation box, with an elastic bottom sheet installed on the top side of the bottom clamp plate, and a pull spring and a positioning pull spring connected in a circumferential manner on the inner side of the bottom of the logistics transportation box; a top clamp plate located inside the top of the logistics transportation box, and above the bottom clamp plate, with transmission nuts connected to both sides of the top clamp plate, and an elastic top sheet installed on the bottom side of the top clamp plate; two vertical clamping rods connected to both sides of the top clamp plate, and the vertical clamping rods connected to a parallel connecting rod, which is connected to a drive rod, with the lower end of the drive rod connected to the bottom clamp plate and the upper end of the drive rod connected to the top clamp plate; a manual gear installed on the top of the top clamp plate, and the manual gear connected to the transmission nut; a movable frame and a sealing cover installed inside the top of the logistics transportation box, with the bottom side of the sealing cover contacting the top side of the movable frame, and fixing hooks provided at both ends of the top of the logistics transportation box, the fixing hooks contacting the top ends of the sealing cover.

[0007] Optionally, two sliding holes are provided on both sides of the top clamping plate, and the top of the vertical clamping rod is slidably connected to the sliding hole. Two bottom connecting holes are provided on both sides of the bottom clamping plate, and a slider is provided at the bottom end of the vertical clamping rod, which is slidably connected to the bottom connecting hole.

[0008] Optionally, the slider is inclined, the bottom side of the bottom connecting hole is inclined, and the inclined end face of the slider slides in contact with the inclined end face of the bottom connecting hole.

[0009] Optionally, square insertion holes are provided on both sides of the bottom clamping plate, and a square insertion rod is provided at the bottom of the drive rod. The square insertion rod is slidably inserted into the square insertion hole. One end of the parallel connecting rod is rotatably connected to the drive rod, and the other end of the parallel connecting rod is rotatably connected to the vertical clamping rod. The two parallel connecting rods connected to the drive rod are parallel to each other.

[0010] Optionally, the transmission nuts are rotatably connected to both sides of the top clamping plate, and the top of the drive rod is provided with a screw, which is threaded into the transmission nut.

[0011] Optionally, the top of the transmission nut is provided with a driven gear, and a manual gear is rotatably connected to the top side of the top clamping plate. The manual gear meshes with the driven gears on the top of the two transmission nuts respectively.

[0012] Optionally, the bottom end of the pull-down spring is connected to the inside of the logistics transport box, the top end of the pull-down spring is connected to the bottom clamping plate, and the pull-down spring is inclined at 45 degrees.

[0013] Optionally, the bottom end of the upper tension spring is connected to the top clamping plate, and the top end of the upper tension spring is connected to the movable frame. The movable frame is slidably placed inside the logistics transport box, and the upper tension spring is inclined at 45 degrees.

[0014] Optionally, the top end of the positioning spring is connected to the inside of the logistics transport box, the bottom end of the positioning spring is connected to the bottom clamping plate, and the positioning spring is inclined at 45 degrees.

[0015] Beneficial effects

[0016] According to various embodiments of the present invention, the protective storage box for high-precision mold logistics transportation, compared with the traditional mold logistics transportation storage box, when the slider at the bottom end of the vertical clamping rod is inserted into the bottom connecting hole opened in the bottom clamping plate, moves the two vertical clamping rods outward, increasing the distance between the two vertical clamping rods. The slider is affected by the inclined end face of the bottom side of the bottom connecting hole, which drives the top clamping plate to move downward, reducing the distance between the top clamping plate and the bottom clamping plate. This allows the elastic bottom rubber sheet on the top side of the bottom clamping plate and the elastic top rubber sheet on the bottom side of the top clamping plate to tightly clamp the upper and lower sides of the high-precision mold, achieving the effect of clamping and fixing the high-precision mold and ensuring the stability of the high-precision mold logistics transportation state.

[0017] Furthermore, through the configuration of the transmission nut, drive rod, and parallel connecting rod, when the slider at the bottom end of the vertical clamping rod is inserted into the bottom connecting hole of the bottom clamping plate, the square insert at the bottom of the drive rod is inserted into the square insert hole of the bottom clamping plate. The transmission nut drives the drive rod to move upward along the square insert hole, thereby driving the two vertical clamping rods to move outward synchronously through the parallel connecting rod connected to the drive rod, achieving a high-precision mold clamping and fixing effect, making the fixing of high-precision molds easier. In addition, with the setting of the manual gear, the manual gear drives the two transmission nuts to rotate synchronously, thereby driving the two drive rods to move up and down synchronously through the transmission nuts, ensuring the synchronicity of the inward and outward movement adjustment of the two sets of vertical clamping rods, making the operation even simpler.

[0018] Furthermore, the use of pull-down and positioning springs allows the high-precision mold to be suspended inside the logistics transport box during clamping, providing space for force relief and buffering. When the outside of the logistics transport box is subjected to external impact, the pull-down and positioning springs buffer the impact force, providing all-round protection for the high-precision mold and preventing damage from rough transportation, thus affecting its performance. In addition, the positioning springs apply tension to the bottom clamping plate when the high-precision mold is removed from the logistics transport box, fixing the bottom clamping plate and ensuring its stability. This allows the bottom slider of the vertical clamping rod and the square insert at the bottom of the drive rod to be inserted into the bottom connecting hole and square insert hole of the bottom clamping plate, enabling reuse. The positioning springs also provide auxiliary buffering for the high-precision mold, further ensuring the protective effect during transportation. Attached Figure Description

[0034] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0035] Example:

[0036] Please refer to Figures 1 to 10 :

[0037] This invention proposes a protective storage box for high-precision mold logistics transportation, comprising: a logistics transportation box 1 and a top clamping plate 5; a bottom clamping plate 2 is installed inside the bottom of the logistics transportation box 1, and an elastic bottom rubber sheet 201 is installed on the top side of the bottom clamping plate 2; a pull spring 3 and a positioning pull spring 4 are connected in a circumferential manner to the inner side of the bottom of the logistics transportation box 1; the top clamping plate 5 is located inside the top of the logistics transportation box 1, and is located on top of the bottom clamping plate 2; transmission nuts 6 are respectively connected to both sides of the top clamping plate 5, and an elastic top rubber sheet 501 is installed on the bottom side of the top clamping plate 5; Two vertical clamping rods 7 are connected to each side of the clamping plate 5, and the vertical clamping rods 7 are connected to the parallel connecting rod 9. The parallel connecting rod 9 is connected to the driving rod 8, and the lower end of the driving rod 8 is connected to the bottom clamping plate 2, and the upper end of the driving rod 8 is connected to the top clamping plate 5. Two sliding holes 502 are opened on each side of the top clamping plate 5, and the top of the vertical clamping rod 7 is slidably connected to the sliding hole 502. Two bottom connecting holes 203 are opened on each side of the bottom clamping plate 2, and a slider 701 is provided at the bottom end of the vertical clamping rod 7. The slider 701 is slidably connected to the bottom connecting hole 203, and the slider 701 is inclined. The bottom connecting hole 203 is inclined, and the inclined end face of the slider 701 slides in contact with the inclined end face of the bottom connecting hole 203. When the slider 701 at the bottom end of the vertical clamping rod 7 is inserted into the bottom connecting hole 203 of the bottom clamping plate 2, the two vertical clamping rods 7 are moved outward, increasing the distance between the two vertical clamping rods 7. The slider 701 is affected by the inclined end face of the bottom connecting hole 203, which drives the top clamping plate 5 to move downward, reducing the distance between the top clamping plate 5 and the bottom clamping plate 2, so that the elastic bottom film 201 on the top side of the bottom clamping plate 2 and the elastic bottom film 201 on the bottom side of the top clamping plate 5 are in contact. The top rubber sheet 501 is tightly clamped on the upper and lower sides of the high-precision mold, which can clamp and fix the high-precision mold and ensure the stability of the high-precision mold in logistics transportation. The top clamping plate 5 is equipped with a manual gear 13, which is connected to the transmission nut 6. The top of the logistics transportation box 1 is equipped with a movable frame 10 and a sealing cover 12, and the bottom side of the sealing cover 12 is in contact with the top side of the movable frame 10. The top two ends of the logistics transportation box 1 are respectively provided with a cover hook 101, which is in contact with the top two ends of the sealing cover 12.

[0038] Furthermore, according to embodiments of the present invention, refer to the appendix Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, square insertion holes 202 are respectively opened on both sides of the bottom clamping plate 2. A square insertion rod 801 is provided at the bottom of the drive rod 8. The square insertion rod 801 is slidably inserted into the square insertion hole 202. One end of the parallel connecting rod 9 is rotatably connected to the drive rod 8, and the other end of the parallel connecting rod 9 is rotatably connected to the vertical clamping rod 7. The two parallel connecting rods 9 connected to the drive rod 8 are parallel to each other. The transmission nuts 6 are rotatably connected to both sides of the top clamping plate 5. A screw 802 is provided at the top of the drive rod 8. The screw 802 is threadedly connected to the transmission nut 6.

[0039] Using the above technical solution, when the bottom slider 701 of the vertical clamping rod 7 is inserted into the bottom connecting hole 203 of the bottom clamping plate 2, the bottom square insert 801 of the drive rod 8 is inserted into the square insertion hole 202 of the bottom clamping plate 2. The drive rod 8 is driven to move upward along the square insertion hole 202 through the transmission nut 6, thereby driving the two vertical clamping rods 7 to move outward synchronously through the parallel connecting rod 9 connected to the drive rod 8, so as to achieve the high-precision mold clamping and fixing effect, making the high-precision mold fixing more convenient.

[0040] Furthermore, according to embodiments of the present invention, refer to the appendix Figure 6 As shown, the top of the transmission nut 6 is provided with a driven gear 601, and the manual gear 13 is rotatably connected to the top side of the top clamping plate 5. The manual gear 13 meshes with the driven gears 601 on the top of the two transmission nuts 6 respectively.

[0041] By adopting the above technical solution, the two transmission nuts 6 are rotated synchronously by the manual gear 13, thereby driving the two drive rods 8 to move up and down synchronously through the transmission nuts 6, ensuring the synchronicity of the inward and outward movement adjustment of the two sets of vertical clamping rods 7, and making the operation simpler.

[0042] Furthermore, according to embodiments of the present invention, refer to the appendix Figure 3 , Figure 5 and Figure 9 As shown, the bottom end of the pull spring 3 is connected to the inside of the logistics transport box 1, the top end of the pull spring 3 is connected to the bottom clamping plate 2, and the pull spring 3 is inclined at 45 degrees. The bottom end of the upper pull spring 11 is connected to the top clamping plate 5, and the top end of the upper pull spring 11 is connected to the movable frame 10. The movable frame 10 is slidably placed inside the logistics transport box 1, and the upper pull spring 11 is inclined at 45 degrees.

[0043] By adopting the above technical solution, the high-precision mold in the clamping state is suspended inside the logistics transport box 1 by the pull spring 3 and the pull spring 11, which provides space for the high-precision mold to unload and buffer. When the outside of the logistics transport box 1 is hit by an external force, the pull spring 3 and the pull spring 11 buffer the impact force, which plays a role in protecting the high-precision mold in all aspects and avoids damage to the high-precision mold due to violent transportation, thus affecting the use effect of the high-precision mold.

[0044] Furthermore, according to embodiments of the present invention, refer to the appendix Figure 2 and Figure 7 As shown, the top end of the positioning spring 4 is connected to the inside of the logistics transport box 1, the bottom end of the positioning spring 4 is connected to the bottom clamping plate 2, and the positioning spring 4 is inclined at 45 degrees.

[0045] Using the above technical solution, when the high-precision mold is taken out from the inside of the logistics transport box 1, the positioning tension spring 4 applies a pulling force to the bottom clamping plate 2, which fixes the bottom clamping plate 2 and ensures the stability of the bottom clamping plate 2. This allows the bottom slider 701 of the vertical clamping rod 7 and the bottom square insertion rod 801 of the drive rod 8 to be inserted into the bottom connecting hole 203 and the square insertion hole 202 opened in the bottom clamping plate 2, respectively, so as to achieve reuse. The positioning tension spring 4 also provides auxiliary buffering for the high-precision mold, further ensuring the protective effect of the high-precision mold during transportation.

[0046] The specific usage and function of this embodiment: When using this invention, the high-precision mold is placed on the elastic bottom sheet 201 at the top of the bottom clamping plate 2. The bottom slider 701 of the vertical clamping rod 7 is inserted into the bottom connecting hole 203 opened in the bottom clamping plate 2. The square insert 801 at the bottom of the drive rod 8 is inserted into the square insert 202 opened in the bottom clamping plate 2. Next, the manual gear 13 is rotated, which drives the two transmission nuts 6 to rotate synchronously. The transmission nuts 6 drive the drive rod 8 to move upward along the square insert 202, thereby connecting the drive rod 8 to the bottom clamping plate 2. The parallel connecting rod 9 drives the two vertical clamping rods 7 to move outward synchronously, increasing the distance between the two vertical clamping rods 7. The slider 701, affected by the inclined end face of the bottom connecting hole 203, drives the top clamping plate 5 to move downward, reducing the distance between the top clamping plate 5 and the bottom clamping plate 2. This allows the elastic bottom rubber sheet 201 on the top side of the bottom clamping plate 2 and the elastic top rubber sheet 501 on the bottom side of the top clamping plate 5 to tightly clamp the upper and lower sides of the high-precision mold, achieving the effect of clamping and fixing the high-precision mold and ensuring the stability of the high-precision mold in logistics transportation. Then, the sealing cover 12 is installed in the logistics transportation. Inside the top of the transport box 1, the sealing cover 12 is fixed by the fastening hooks 101 at both ends of the top of the transport box 1, allowing for logistics transportation operations. During the logistics transportation of the high-precision mold, the high-precision mold in a clamped state is suspended inside the transport box 1 by the pull spring 3 and the pull spring 11, reserving space for force relief and buffering of the high-precision mold. When the outside of the transport box 1 is subjected to external force collision, the pull spring 3 and the pull spring 11 buffer the impact force, providing all-round protection for the high-precision mold and preventing it from being damaged during rough transportation. Damage affects the performance of the high-precision mold. When the high-precision mold is taken out of the logistics transport box 1, the positioning tension spring 4 applies tension to the bottom clamping plate 2 to fix the bottom clamping plate 2 and ensure the stability of the bottom clamping plate 2. This allows the bottom slider 701 of the vertical clamping rod 7 and the bottom square insertion rod 801 of the drive rod 8 to be inserted into the bottom connecting hole 203 and the square insertion hole 202 of the bottom clamping plate 2, respectively, so as to achieve reuse. The positioning tension spring 4 also provides auxiliary buffering for the high-precision mold, further ensuring the protective effect of the high-precision mold during transportation.

[0047] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.
