Description

Technical Field

[0001] This utility model belongs to the technical field of footwear processing, specifically relating to an electromagnetic mold last locking device. Background Technology

[0002] During the shoe manufacturing process, after the shoe is fitted into the mold, it needs to be roughened and glued with precise trajectory. In some processes, the mold is fixed on a tray, and the production line needs a robotic arm to grab the tray together. At this time, the mold on the production line must be clamped on the tray to prevent it from shaking back and forth, otherwise it will affect the quality of the shoes.

[0003] It is difficult to secure the mold to the tray while also making it easy to separate the two. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to design an electromagnetic mold locking device that makes it easy for the mold to shrink onto the tray, and at the same time makes it easy to separate the two.

[0005] The specific technical solution of this utility model is as follows:

[0006] An electromagnetic mold last locking device includes a tray and a mold last base. A base is fixed on the tray, and a magnetic base is fixed on the base. The magnetic base generates magnetic force by being energized and de-energized. The mold last base cooperates with the magnetic base, and the mold last base is provided with a connector for connecting to the mold last.

[0007] Two inserts are fixed on the tray, and both the mold iron base and the magnetic base are provided with through holes for the inserts to pass through.

[0008] The lower part of the insert is threaded to the tray, and the lower end of the insert is threaded to fit a nut.

[0009] The base is made of plastic.

[0010] The base has an internal mounting chamber where an electromagnet is fixed. The electromagnet is in contact with the magnetic base. The mounting chamber has mounting holes on the side, and the electromagnet's terminals extend from the mounting holes to the outside. The power supply connected to the terminals is fixed on the base.

[0011] The connecting parts are bolts or screws.

[0012] The contact surfaces of the mold base and the magnetic base are both flat.

[0013] Compared with the prior art, the technical effect of this utility model is that it uses the energization and de-energization of an electromagnet to control the "contraction and unlocking of the mold and the tray", which makes it easy for the mold to be contracted onto the tray, and also makes it easy to separate the two. Attached Figure Description

[0014] Figure 1This is a schematic diagram of the utility model in use. Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 An electromagnetic mold last locking device includes a tray 10 and a mold last base 20. A base 11 is fixed on the tray 10, and a magnetic base 13 is fixed on the base 11. The magnetic base 13 generates magnetic force by being energized and de-energized. The mold last base 20 cooperates with the magnetic base 13, and the mold last base 20 is provided with a connector 21 for connecting to the mold last.

[0017] To facilitate alignment, two inserts 12 are fixed on the tray 10, and both the mold iron base 20 and the magnetic base 13 are provided with through holes for the inserts 12 to pass through.

[0018] To facilitate adjustment of the extension length of the insert 12, the lower part of the insert 12 is threadedly connected to the tray 10, and the lower end of the insert 12 is threaded with a nut.

[0019] To reduce the impact on magnetic force, the base 11 is made of plastic.

[0020] To protect the electromagnet, the base 11 has an internal mounting chamber 14, in which the electromagnet 15 is fixed. The electromagnet 15 is in contact with the magnetic base 13. The mounting chamber 14 has a mounting hole on its side, and the terminal 16 of the electromagnet 15 extends from the mounting hole to the outside. The power source (such as a battery, not shown in the figure) connected to the terminal 16 is fixed on the base 11.

[0021] For easy disassembly, the connector 21 is a bolt or screw.

[0022] To facilitate locking, the contact surfaces of the mold base 20 and the magnetic base 13 are both flat.

[0023] Its working principle is as follows:

[0024] S1. Installation: Fix the two connectors 21 onto the mold 90 to complete the fixing of the mold base 20 and the shoe last.

[0025] S2. Inserting the mold: After the tray is in place on the production line, insert the two aforementioned inserts 12 through the through holes of the mold base 20 and the magnetic guide base 13 into the mold insertion hole to complete the positioning of the tray 10 and the mold 90. If the length of the insert 12 does not match the depth of the mold insertion hole, the length of the insert 12 extending out of the magnetic guide base 13 can be adjusted.

[0026] S3. Fixing the mold: The electromagnet 15 is energized and generates a magnetic force, which is transmitted to the magnetic conductor seat 13, thereby attracting the mold iron seat 20 together, thus fixing the mold 90 and the tray 10 together.

[0027] In this step, the electromagnet 15 is energized and generates magnetic force, thereby completing the locking of the mold iron base 20 and the magnetic guide base 13, thus fixing the mold 90 and the tray 10 together.

[0028] S4, track roughening, glue application, and other operations. This is existing technology and will not be described in detail.

[0029] S5. Release the mold: After all processes on the production line (such as roughening the track, applying glue, etc.) are completed, the control electromagnet 15 is de-energized, its magnetic force disappears, the mold iron seat 20 and the magnetic guide seat 13 are in the unlocked state, there is no attraction between the mold 90 and the tray 10, and the mold 91 loses its constraint.

[0030] S6. Take away the mold: Once the mold 91 is no longer constrained, it can be easily taken away.

[0031] Homework completed.

[0032] For other details, please refer to the existing technology.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
