Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a mold with a protection mechanism. Background Art

[0002] The principle of induction cooker is electromagnetic induction, that is, using alternating current to pass through the coil to generate an alternating magnetic field with constantly changing direction. Eddy current will appear inside the conductor in the alternating magnetic field (the reason can be found in Faraday's law of electromagnetic induction). This is because the eddy electric field drives the movement of carriers in the conductor (the ones in the pot are electrons, not iron atoms); the Joule heating effect of the eddy current causes the conductor to heat up, thereby achieving heating. During the processing of the induction cooker, the bottom shell needs to be processed using a mold, so a mold is needed.

[0003] However, the existing molds in the market have poor protection mechanisms during use. When employees replace the lower mold, they may accidentally touch it, causing the upper mold to press down and injure the employees. It is also inconvenient to clean the debris generated during processing.

[0004] Therefore, it is necessary to provide a mold with a protective mechanism to solve the above technical problems. Utility Model Content

[0010] Compared with the related art, the mold with a protective mechanism provided by the utility model has the following advantages:

[0011] Beneficial effects:

[0012] When the lower mold needs to be replaced, the upper mold moves to the top. At this time, the motor works to drive the forward and reverse screws to rotate. The rotation of the forward and reverse screws effectively changes the distance between the two moving blocks, thereby changing the positions of the two support rods.

The bottom of the base 1 is fixedly installed with a slide rail 15, and the number of slide rails 15 is two. The bottom of the base 1 is slidably installed with a collection box 16 along the length direction of the slide rail 15 through the slide rail 15. The collection box 16 is located directly below the four second feed troughs 11. A handle 17 is fixedly installed on one side of the outside of the collection box 16.

The upper mold 7 is effectively driven to move up and down through the work of the hydraulic cylinder.

[0022] The working principle of a mold with a protective mechanism provided by the utility model is as follows:

[0023] The first step: when the lower mold 9 needs to be replaced, the upper mold 7 moves to the top. At this time, the motor 4 works to drive the forward and reverse screws 3 to rotate. The rotation of the forward and reverse screws 3 effectively changes the distance between the two moving blocks 5, and then changes the position of the two support rods 6. The support rods 6 are located directly below the positioning blocks 8. If the upper mold 7 is accidentally pressed down during the replacement process, it is easy to cause injury to the staff. Through the setting of the support rods 6, the upper mold 7 is pressed down, and the top of the support rods 6 enters the interior of the positioning block 8 to play a supporting role, avoiding the upper mold 7 from being pressed down, greatly improving the safety, and having a good protective mechanism.

[0024] Step 2: The top of the top plate 13 is fixedly installed with the hydraulic cylinder, and one end of the hydraulic cylinder penetrates the top plate 13 and is fixed to the upper mold 7. The upper mold 7 is effectively driven to move up and down through the operation of the hydraulic cylinder. The upper mold 7 is pressed down, and the sheet metal is stamped. The waste generated by the stamping passes through the lower mold 9 through the first discharge chute 10, and then passes through the base 1 through the second discharge chute 11, and effectively falls into the interior of the collection box 16 for collection. It has the function of waste collection, and the cooperation of the handle 17 and the slide rail 15 facilitates the installation or disassembly of the collection box 16, which is convenient for centralized processing of the collected waste, thereby greatly improving practicality.

[0025] Compared with the related art, the mold with a protective mechanism provided by the utility model has the following advantages:

[0026] Beneficial effects:

[0027] When the lower mold 9 needs to be replaced, the upper mold 7 moves to the top. At this time, the motor 4 works to drive the forward and reverse screws 3 to rotate. The rotation of the forward and reverse screws 3 effectively changes the distance between the two moving blocks 5, thereby changing the positions of the two support rods 6. The support rods 6 are located directly below the positioning blocks 8. If the upper mold 7 is accidentally pressed down during the replacement process, it is easy to cause injuries to the staff. By setting the support rods 6, the upper mold 7 is pressed down, and the top of the support rods 6 enters the interior of the positioning block 8 to play a supporting role, thereby preventing the upper mold 7 from being pressed down, greatly improving safety, and having a good protective mechanism.

[0028] The upper mold 7 is pressed downward, and the sheet metal is punched. The waste generated by the punching passes through the lower mold 9 through the first feeding chute 10, and then passes through the base 1 through the second feeding chute 11, and effectively falls into the interior of the collection box 16 for collection. It has the function of waste collection, and the cooperation of the handle 17 and the slide rail 15 facilitates the installation or disassembly of the collection box 16, which facilitates the centralized treatment of the collected waste, thereby greatly improving the practicality.
