Description

Technical Field

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

[0002] A mold is a special tool that changes the shape of an object through the physical state of the molding material. The most common molds are stamping molds. With the development of the logistics industry, molds are usually sent to customers by logistics. In order to avoid damage to some high-precision molds during logistics transportation, it is necessary to use protective storage boxes to store high-precision molds.

[0003] There are similar storage boxes for high-precision mold logistics transportation, such as a logistics transportation box mentioned in patent number CN201811438770.9, which includes an outer box body and an inner box body. Grooves are evenly arranged on the bottom plate of the outer box body in the left and right directions, and ice cubes are arranged in the grooves; a support spring is arranged at the bottom of the inner box body, and the support spring is in contact with the ice cubes at the bottom of the outer box body; a spherical groove is evenly arranged on the upper end of the inner box body in the circumferential direction, and an inner box cover is arranged above the inner box body. The inner box cover is connected to the inner box body through a connecting rod made of rubber material arranged on the lower surface of the inner box cover corresponding to the position of the spherical groove on the inner box body, the lower end of the connecting rod is a spherical structure, and a sponge layer is arranged between the inner box body and the inner box cover; an outer box cover is arranged on the top of the outer box body, and corn-shaped teeth are evenly arranged on the outer edge of the lower end of the outer box cover in the circumferential direction; a corn-shaped groove corresponding to the corn-shaped teeth is arranged on the outer edge of the upper end of the outer box body; grooves are evenly arranged on the top of the inner box cover in the left and right directions, and ice cubes are placed in the grooves, and a spring for pressing the ice cubes is arranged on the top of the outer box cover.

[0004] However, the traditional high-precision mold logistics transportation storage boxes have poor fixing, limiting and protecting effects on high-precision molds. Usually, wooden wedges are embedded in the gap between the high-precision mold and the storage box to fix the high-precision mold. When the storage box is subjected to violent transportation, the precision mold is easily affected by inertia and collides 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 the logistics transportation of high-precision molds. When the slider at the bottom end of the vertical clamping rod is inserted into the bottom connecting hole opened by the bottom clamping plate, the two vertical clamping rods are moved outward to increase the distance between the two vertical clamping rods. The slider is affected by the inclined end surface of the bottom side of the bottom connecting hole to drive the top clamping plate to move downward, thereby reducing the distance between the top clamping plate and the bottom clamping plate, so that 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 are tightly clamped on the upper and lower sides of the high-precision mold respectively, thereby playing a clamping and fixing effect on the high-precision mold and ensuring the stability of the logistics transportation state of the high-precision mold.

[0015] Beneficial Effects Compared with the traditional storage box for mold logistics transportation, the protective storage box for high-precision mold logistics transportation according to each embodiment of the present invention has the following characteristics: when the slider at the bottom end of the vertical clamping rod is inserted into the bottom connecting hole opened by the bottom clamping plate, the two vertical clamping rods are moved outward to increase the distance between the two vertical clamping rods, and the slider is affected by the inclined end surface of the bottom side of the bottom connecting hole to drive the top clamping plate to move downward, thereby reducing the distance between the top clamping plate and the bottom clamping plate, so that the elastic bottom rubber film on the top side of the bottom clamping plate and the elastic top rubber film on the bottom side of the top clamping plate are tightly clamped on the upper and lower sides of the high-precision mold respectively, thereby playing a clamping and fixing effect on the high-precision mold and ensuring the stability of the logistics transportation state of the high-precision mold.

[0016] In addition, through the setting of the transmission nut, the driving rod and the parallel connecting rod, when the sliding block at the bottom end of the vertical clamping rod is inserted into the bottom connecting hole opened in the bottom clamping plate, the square plug rod at the bottom of the driving rod is inserted into the square plug hole opened in the bottom clamping plate, and the driving rod is driven to move upward along the square plug hole through the transmission nut, thereby driving the two vertical clamping rods to move outward synchronously through the parallel connecting rod connected to the driving rod, thereby achieving the high-precision mold clamping and fixing effect, making the high-precision mold fixation easier; and in conjunction with the setting of the manual gear, the two transmission nuts are driven to rotate synchronously through the manual gear, thereby driving the two driving rods to move up and down synchronously through the transmission nut, thereby ensuring the synchronization of the inward and outward movement adjustment of the two sets of vertical clamping rods, and making the operation easier.

[0017] In addition, through the setting of the lower tension spring and the positioning tension spring, the lower tension spring and the upper tension spring are used to make the high-precision mold in the clamped state suspended inside the logistics transport box, reserving space for the high-precision mold force unloading buffer. When the outside of the logistics transport box is hit by external force, the lower tension spring and the upper tension spring buffer the impact force, thereby providing all-round protection for the high-precision mold, thereby preventing the high-precision mold from being damaged due to violent transportation and affecting the use effect of the high-precision mold; and in conjunction with the setting of the positioning tension spring, when the high-precision mold is taken out from the inside of the logistics transport box, the positioning tension spring applies tension to the bottom clamping plate, thereby fixing the bottom clamping plate and ensuring the stability of the bottom clamping plate, so that the slider at the bottom end of the vertical clamping rod and the square plug rod at the bottom of the driving rod can be respectively inserted into the bottom connecting hole and the square plug hole opened in the bottom clamping plate to achieve reuse, and the positioning tension spring can provide auxiliary buffering for the high-precision mold, further ensuring the transportation protection effect of the high-precision mold.
