DETAILED DESCRIPTION

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a quick demoulding mold for cylindrical parts, including a support plate 1 and an extrusion mechanism 9. A casting mold 6 is arranged on the front side of the support plate 1. A bottom plate 8 is fixedly installed inside the casting mold 6. The bottom plate 8 is provided with multiple groups of circular holes in a circular array; the extrusion mechanism 9 is arranged on the casting mold 6, and the extrusion mechanism 9 is used to extrude the cast parts and automatically slide them out for collection.

[0024] The extrusion mechanism 9 includes an extrusion rod 901, a connecting circular plate 902, a connecting rod 903 and a sliding ball 904. The number of the extrusion rods 901 is eight groups. The extrusion rods 901 are slidably connected to the bottom plate 8 through the circular holes opened on the bottom plate 8. The bottom of the extrusion rod 901 is fixedly installed with a connecting circular plate 902, and the bottom of the connecting circular plate 902 is fixedly installed with a connecting rod 903. One end of the connecting rod 903 is fixedly installed with a sliding ball 904. When the part is solidified, the sliding ball 904 is driven to slide by the rotation of the casting mold 6, so that the extrusion rod 901 squeezes the bottom of the part upward, so that the part can be separated from the casting mold 6. The part separated from the casting mold 6 slides into the collection box 12 through the guide table 10. The top mold and the demolding are integrated for the newly cast parts, which improves the work efficiency and does not require the operator to manually take the extruded parts for collection.

[0025] An arc plate 2 is fixedly mounted on the front side of the bracket plate 1 , and the top of the arc plate 2 is in contact with the bottom of the sliding ball 904 .

[0026] A motor 3 is fixedly installed on the rear side of the bracket plate 1, and the output shaft of the motor 3 extends to the front side of the bracket plate 1 and is fixedly installed with a connecting short rod 4, a fixing ring 5 is fixedly installed on the front side of the connecting short rod 4, the inner wall of the fixing ring 5 and the casting mold 6 are fixedly installed, and a cylinder 7 is fixedly installed on the top of the base plate 8, and the casting mold 6 includes the cylinder 7.

[0027] A guide platform 10 is fixedly mounted on the front side of the bracket plate 1 .

[0028] Two sets of support plates 11 are fixedly mounted on the bottom of the bracket plate 1 .

[0029] A collecting box 12 is provided on the side of the guide platform 10 .

[0030] Working principle: when work is needed, the material melted into molten iron is put into the casting mold 6. When the molten iron solidifies, the motor 3 is started. The output shaft of the motor 3 rotates to drive the connecting short rod 4 to rotate. The connecting short rod 4 rotates to drive the fixed ring 5 to rotate. The fixed ring 5 rotates to drive the casting mold 6 to rotate. When the casting mold 6 rotates, the sliding ball 904 moves on the arc plate 2. During the movement of the arc plate 2, the sliding ball 904 drives the connecting rod 903 to move. The movement of the connecting rod 903 drives the connecting circular plate 902 to move. The movement of the connecting circular plate 902 drives the extrusion rod 901 to squeeze the bottom of the part upward, and squeeze the part out of the inside of the casting mold 6. When the opening at the top of the casting mold 6 rotates to tilt downward, the part will slide out from the inside of the casting mold 6 to the guide table 10, and slide into the collection box 12 through the guide table 10 for collection.
