Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to an outer cylinder inclined ejection device. Background Art

[0002] The outer drum is a crucial part of a washing machine, located behind the inner drum (the part that comes into direct contact with the clothes). It's also known as the rear outer drum. It's a container wrapped around the inner drum, preventing water from entering the washing machine's structure.

[0003] When using a mold to produce an outer cylinder, the mold's inclined ejector device ejects the undercut portion of the product. Conventional inclined ejectors are not efficient in ejecting the undercut portion. If the device fails to eject smoothly, the undercut portion of the product can become stuck and unable to escape from the mold, making it difficult to eject the product. This requires improvement.

DETAILED DESCRIPTION

[0032] The following is a further detailed description of this application in conjunction with Appendix 1-4.

[0033] The embodiment of the present application discloses an outer cylinder inclined ejection device. Figure 1 The outer tube oblique ejection device includes a mold frame 1, a template 2 fixed to the mold frame 1, a punch 3 fixed to the template 2, and an ejection mechanism 4 mounted on the mold frame 1. The ejection mechanism 4 includes an ejection assembly 41 and an oblique ejection assembly 42. The ejection assembly 41 is used to eject the cylindrical finished outer tube, and the oblique ejection assembly 42 is used to eject the inverted finished outer tube. The ejection assembly 41 includes a plurality of ejector rods 5 for ejecting the finished outer tube.

[0034] Reference Figure 1 and Figure 2 The inclined ejector assembly 42 includes a connecting block 421, a sliding rod 422, and an ejection block 423. The connecting block 421 is used to connect to the driving source. The sliding rod 422 is slidably connected to the mold frame 1. The sliding rod 422 is connected to the connecting block 421. The ejection block 423 includes an upper inclined ejector block 4231 and a lower inclined ejector block 4232, which are connected to each other. The lower inclined ejector block 4232 is connected to the end of the sliding rod 422 away from the connecting block 421. The punch 3 is provided with an ejection groove 6 for accommodating the ejection block 423. When the upper inclined ejector block 4231 is ejected out of the ejection groove 6, the upper inclined ejector block 4231 simultaneously moves in a direction away from the central axis of the punch 3. A connecting protrusion 7 is fixed to the lower inclined ejector block 4232, and a connecting groove 8 is provided on the upper inclined ejector block 4231 for sliding movement of the connecting protrusion 7. Guide protrusions 9 are fixed to both sides of the connecting protrusion 7, and guide grooves 10 are formed on the opposite walls of the connecting groove 8 to accommodate the guide protrusions 9. A limiting protrusion 11 is fixed to the connecting protrusion 7, and a limiting groove 12 is formed on the bottom wall of the connecting groove 8. The limiting protrusion 11 extends into the limiting groove 12, and a limiting arc surface 13 is distributed within the limiting groove 12. When the limiting protrusion 11 abuts the limiting arc surface 13, the limiting protrusion 11 limits the upper inclined ejector block 4231 from further movement in the direction toward or away from the punch 3.

[0035] Reference Figure 3 and Figure 4 A guide block 14 is mounted on the mold frame 1, and an inclined slot 15 is provided on the guide block 14 for sliding the sliding rod 422. A mounting screw 16 is mounted on the mold frame 1, and the mounting screw 16 is used to fix the guide block 14 to the mold frame 1. A mounting groove 17 is provided on the mold frame 1, and the mounting groove 17 is for accommodating the template 2 so that the template 2 can be installed on the mold frame 1.

[0036] Reference Figure 1 A placement area 18 is installed on the mold frame 1, and the placement area 18 is used to place the undercut.

[0037] The implementation principle of the outer cylinder inclined ejection device of the embodiment of the present application is as follows: an ejection assembly 41 is set to eject the outer cylinder finished product, and the undercut finished product of the outer cylinder is ejected by the inclined ejection assembly 42. When ejecting the undercut finished product, the driving source on the lathe drives the connecting block 421 to move, thereby causing the sliding rod 422 to move on the mold frame 1 and causing the ejection block 423 to move upward in the ejection groove 6, and the upper inclined ejection block 4231 gradually disengages. After the upper inclined ejection block 4231 disengages from the ejection groove 6, the upper inclined ejection block 4231 will move in a direction away from the central axis of the punch 3, thereby ejecting the undercut product on the top of the upper inclined ejection block 4231. Then the lower inclined ejection block 4232 continues to move, and the undercut on the outer wall of the lower inclined ejection block 4232 is smoothly ejected. Since the undercut on the upper inclined ejection block 4231 has been ejected, the undercut on the lower inclined ejection block 4232 will not be interfered with by the undercut on the upper inclined ejection block 4231, so that the undercut is ejected, thereby making the demoulding of the undercut efficient and convenient.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
