[0012] Figure 1 This is a cross-sectional schematic diagram of the present invention. Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1 A production line tray and mold fixing mechanism includes a production line 10, the production line 10 includes a transmission line 11, a section of the production line 10 is a leather-covering operation area 12, an upper-lifting cylinder 20 is provided on the inner side of the production line 10 at the leather-covering operation area 12, and a lower-pulling cylinder 41 is provided on the outer side of the production line 10 at the leather-covering operation area 12.

[0015] A mold tray 30 is provided on the transmission line 11. A mold base 32 is fixed on the upper surface of the mold tray 30. A mold base 32 is provided with a mold fixing post 34 for fixing a mold 35. An electromagnet 34 is provided on the mold base 32. The contact A31 of the circuit connected to the electromagnet 34 is located on the lower surface of the mold tray 30. The contact B21 of the circuit connected to the electromagnet 34 is located on the upper surface of the piston end of the upper cylinder 20. When the contact A31 and the contact B21 are in contact, the circuit connected to the electromagnet 34 is connected; when the contact A31 and the contact B21 are not in contact, the circuit connected to the electromagnet 34 is disconnected.

[0016] The piston end of the pull-down cylinder 41 is fixed with a pressure plate 40. One end of the pressure plate 40 extends into the inside of the production line 10 and is located above the mold tray 30.

[0017] To reduce the impact force, the piston end of the upper cylinder 20 is fixed with a contact plate 22, and the contact B21 is located on the upper surface of the contact plate 22. The upper surface of the contact plate 22 or the lower surface of the mold tray 30 is fixed with an anti-collision pad 23.

[0018] In order to buffer the pressure of the pressure plate 40, a buffer pad 44 is fixed on the lower surface of the inner end of the pressure plate 40.

[0019] In order to make the operation of the pressure plate 40 more stable, the outer end of the pressure plate 40 is fixed with a slide rod 42, which slides through the track 43, and the track 43 is fixed on the cylinder body of the pull-down cylinder 41.

[0020] Its working principle is as follows:

[0021] S1, in position: The mold tray 30 (product tray) is driven into the leather surface working area 12 by the chain roller of the production line 11. After the position sensor senses that it is in position, the production line 11 stops.

[0022] S2. Insert the mold: Insert the mold 35 (usually a plastic mold with a 3-5mm iron plate at the bottom) into the mold fixing post 34.

[0023] S3. Fixing the mold: The piston end of the upper cylinder 20 extends and moves upward, bringing contact A31 into contact with contact B21, energizing the circuit connected to the electromagnet 34, and magnetizing the electromagnet 34. At the same time, the piston end lifts the mold tray 30, causing it to leave the transmission line 11. Then, the control system supplies air to the lower cylinder 41 through the solenoid valve, causing its piston end to retract and move downward. The lower surface of the inner end of the pressure plate 40 remains horizontal during the downward pressing action, and the buffer pad 44 contacts the mold tray 1, attracting and fixing the mold.

[0024] In this step, the mold tray 30 leaves the transmission line 11 without affecting the continued movement of the transmission line 11.

[0025] S4. Applying the leather backing. This is existing technology and will not be described in detail.

[0026] S5. Release the mold: The piston end of the upper cylinder 20 retracts and moves downward, so that the contact A31 and the contact B21 are no longer in contact, thus disconnecting the circuit connected to the electromagnet 34. The mold is released by demagnetizing the electromagnet 34.

[0027] S6. Remove the mold: Once the mold 35 is no longer constrained, it can be easily removed.

[0028] S7. The production line continues to move: the piston end of the pull-down cylinder 41 extends and moves upward, the pressure plate 40 also moves upward, the buffer pad 44 leaves the mold tray 30, the mold tray 1 loses its constraint, the production line continues to move, and transports the mold tray 30 (product tray) to the downstream.

[0029] Homework completed.

[0030] For other details, please refer to the existing technology.

[0031] 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.
