Technical Field

[0001] The present application relates to the technical field of hot pressing devices, and in particular to a mobile phone case logo hot pressing jig. Background Art

[0002] In industrial production, especially in the production of mobile phone cases, the outer surface of the mobile phone case is usually covered with artificial leather to facilitate the imprinting of logos and other marks on the back of the mobile phone case. Therefore, it is necessary to perform heat pressing treatment on the back of the mobile phone case through a heat pressing device to form a logo mark on the back of the mobile phone case.

[0003] However, the existing hot pressing device is relatively complicated to operate, which is not conducive to achieving rapid hot pressing processing of products, and therefore needs further improvement. Utility Model Content

[0004] In order to improve the hot pressing efficiency of products, the present application provides a mobile phone case logo hot pressing jig.

[0005] The mobile phone case logo hot pressing jig provided in this application adopts the following technical solution:

[0006] A mobile phone case logo hot pressing jig comprises a base, a plurality of guide columns fixedly connected to the base, a support top plate fixedly connected to the upper part of the guide columns and located above the base, a movable plate slidably connected to the guide columns, and a driving member driving the movable plate to slide, wherein the base is provided with a tooling seat for positioning and placing the mobile phone case, and the movable plate is provided with a hot pressing head for hot pressing the mobile phone case.

[0007] By adopting the above technical solution, after the mobile phone case is positioned and placed on the tooling seat, the driving member drives the movable plate to slide toward the tooling seat, and the movement of the movable plate drives the hot pressing head to abut against the back of the mobile phone case, thereby forming a logo on the back of the mobile phone case. After the hot pressing is completed, the driving member drives the movable plate to slide and reset, thereby improving the hot pressing efficiency of the product.

[0008] Preferably, the tooling seat includes a bottom mold fixedly connected to the base and a carrier placed on the bottom mold, the carrier protruding with a positioning boss inserted into the inner cavity of the mobile phone case, the bottom mold protruding with a positioning pin fixedly connected, at least two positioning pins are provided, and the carrier is provided with a positioning hole for inserting the positioning pin.

[0009] By adopting the above technical solution, the mobile phone case is first placed on the carrier so that the positioning boss on the carrier is inserted into the inner cavity of the mobile phone case, and then the carrier is placed on the bottom mold so that the positioning pin is inserted into the positioning hole, thereby realizing the positioning and placement of the mobile phone case without adjusting the position of the mobile phone case, thereby improving the hot pressing efficiency.

[0010] Preferably, the driving member is a lifting cylinder, a cylinder body of the lifting cylinder is fixedly connected to the supporting top plate, and a piston rod of the lifting cylinder is fixedly connected to the movable plate.

[0011] By adopting the above technical solution, the lifting and sliding of the movable plate is achieved by extending and retracting the piston rod of the lifting cylinder, and the response speed of the cylinder is fast, which effectively improves the hot pressing efficiency.

[0012] Preferably, the movable plate is fixedly connected to a heat insulation plate, the heat insulation plate is fixedly connected to a heating plate, and the hot pressing head is fixedly connected to the heating plate.

[0013] By adopting the above technical solution, a heat insulation plate is arranged between the heating plate and the movable plate to reduce the heat generated by the heating plate from being transferred to the movable plate.

[0014] Preferably, the movable plate is protrudingly fixed with a first limiting column abutting against the base.

[0015] By adopting the above technical solution, a first limiting column is added to the movable plate. When the driving member drives the movable plate to slide toward the tooling seat and the first limiting column abuts against the base, the thermal pressing head is pressed onto the back of the mobile phone case to a certain depth to prevent the possibility of overpressure on the thermal pressing head.

[0016] Preferably, the base is detachably connected to a second limiting column abutting against the movable plate.

[0017] By adopting the above technical solution, a second limiting column is added to the base. When the driving member drives the movable plate to slide toward the tooling seat and the second limiting column abuts against the movable plate, the hot pressing head is pressed onto the back of the mobile phone case to a certain depth to prevent the possibility of overpressure on the hot pressing head.

[0018] Preferably, the second limiting column is provided with a mounting countersunk hole, and the second limiting column is provided with a countersunk bolt passing through the mounting countersunk hole and threadedly connected to the base, and a plurality of gaskets sleeved on the threaded section of the countersunk bolt are provided between the second limiting column and the base.

[0019] By adopting the above technical solution, the height position of the limit column is adjusted by replacing the number of gaskets, thereby adjusting the hot pressing depth of the hot pressing head.

[0020] Preferably, a high temperature resistant film is covered between the thermal pressing head and the mobile phone shell.

[0021] By adopting the above technical solution, a high temperature resistant film is arranged between the hot pressing head and the mobile phone shell, so that the hot pressing head abuts against the high temperature resistant film to perform hot pressing operation on the mobile phone shell, making the hot pressing molded logo smoother.

[0022] Preferably, the movable plate is provided with a unwinding roller and a winding roller respectively located on both sides of the hot pressing head, one end of the high temperature resistant film is wound around the unwinding roller, and the other end of the high temperature resistant film is wound around the winding roller, and the high temperature resistant film covers the hot pressing head. The movable plate is provided with an unwinding motor for driving the unwinding roller to rotate and an unwinding motor for driving the winding roller to rotate.

[0023] By adopting the above technical solution, under normal circumstances, the high temperature resistant film is in a taut state. When the position of the high temperature resistant film needs to be switched, the unwinding motor and the winding motor are started at the same time, the unwinding roller performs the unwinding operation, and the winding roller performs the winding operation, thereby realizing the position switching of the high temperature resistant film.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. After positioning the mobile phone case on the tooling seat, the driving member drives the movable plate to slide toward the tooling seat. The movement of the movable plate drives the hot pressing head to abut against the back of the mobile phone case, thereby forming a logo on the back of the mobile phone case. After the hot pressing is completed, the driving member drives the movable plate to slide and reset, thereby improving the hot pressing efficiency of the product;

[0026] 2. The movable plate is additionally provided with a first limiting column. When the driving member drives the movable plate to slide toward the tooling seat and the first limiting column abuts against the base, the thermal pressing head is pressed against the back of the mobile phone case to a certain depth to prevent the thermal pressing head from being over-pressurized;

[0027] 3. A high temperature resistant film is arranged between the hot pressing head and the mobile phone shell, so that the hot pressing head abuts against the high temperature resistant film to perform hot pressing operation on the mobile phone shell, making the hot pressing formed logo smoother.
