[0025] like Figure 1 - Figure 8As shown, a barrel-type parts processing mold according to the present invention comprises an upper mold 1 and a lower mold 2, a telescopic cylinder 3 is arranged between the upper mold 1 and the lower mold 2, an abutment mechanism 4 for abutting against the inner wall of the barrel is fixedly arranged on the upper mold 1, the abutment mechanism 4 comprises a core rod 41, a fixed plate 42, a telescopic abutment plate 43, a pressing plate 44 and a pressure cover 45, the core rod 41 comprises an upper end 411 and a lower end 412, the core rod 41 is fixedly arranged with the upper mold 1, the fixed plate 42 is slidably arranged with the upper end 411, and the number of the telescopic abutment plates 43 is set. There are multiple and evenly arranged along the circumferential direction of the fixed plate 42, a limit groove 46 is provided on the telescopic abutment plate 43, a limit rod 47 is fixedly provided on the fixed plate 42, and the number of the limit rods 47 corresponds to the limit groove 46, the limit rod 47 extends to the bottom of the limit groove 46 and is fixedly arranged on the pressure plate 44, a return spring is fixedly arranged between the limit rod 47 and the limit groove 46, the telescopic abutment plate 43 and the pressure plate 44 are both slidably arranged with the lower end portion 412, the pressure cover 45 is fixedly arranged with the bottom of the core rod 41, and the lower mold 2 is provided with a The detection mechanism 5 for detecting the abutment strength of the cylinder is preferably configured such that the cross-sectional shape of the bottom of the upper end portion 411 is set to be conical, and the lower end portion 412 is cylindrical. First, the cylinder to be processed is placed in the groove 7 inside the lower mold 2, and the upper mold 1 is driven downward by starting the cylinder to make the core rod 41 located inside the cylinder. The upper mold 1 is continuously pressed downward to make the pressing plate 44 abut against the bottom wall of the groove 7, thereby making the fixed plate 42, the telescopic abutment plate 43, and the pressing plate 44 rise, so that the telescopic abutment plate 43 slides along the surface of the core rod 41. Thus, while sliding from the lower end 412 to the upper end 411, the upper end 411 and the lower end 412 of the core rod 41 are of different thicknesses, so that the telescopic abutment plate 43 slides outward through the pressure of the upper end 411, so that the multiple telescopic abutment plates 43 abut against various angles of the cylinder to fix the position of the cylinder, which is convenient for the subsequent stamping between molds and has a small size. It is suitable for cylinders with smaller internal space in the product and is easy to adjust during the subsequent maintenance process without disassembling the mold, and can be used with other mold products.

[0026] The detection mechanism 5 includes a positioning ring plate 51, a first gear 52, a second gear 53, a motor 54 and a detection member 55. The positioning ring plate 51 is fixedly arranged inside the lower mold 2. The first gear 52 is rotatably arranged inside the positioning ring plate 51 through a bearing. The second gear 53 is meshed with the first gear 52 and is rotatably arranged on the positioning ring plate 51 through a bearing. The motor 54 is fixedly arranged inside the lower mold 2 and the output end is fixedly arranged with the second gear 53. A slide groove is provided on the positioning ring plate 51. The detection member 55 is fixedly arranged with the first gear 52 and is slidably arranged with the slide groove. Component 55 includes a first plate 551, a second plate 552, an arc plate 553, a roller 554 and a resistance sensor 555. The first plate 551 is arranged on the inner wall of the first gear 52. The second plate 552 is slidably arranged inside the first plate 551 through a return spring. The arc plate 553 is fixedly arranged on the second plate 552.

The detection groove 8 matches the position of the detection member 55. Preferably, the upper mold 1 is provided with a punch head 6 for punching the cylinder port. The cross-sectional shape of the punch head 6 is set to an inverted triangle. In order to avoid the situation where one of the telescopic abutment plates 43 is stuck or other situations cause improper abutment at a certain angle in the cylinder, causing damage to the cylinder during mold stamping, it is necessary to use the detection mechanism 5 to detect whether the cylinder abutment is complete after the abutment. Before the motor 54 is started, the roller 554 abuts against the outer wall of the cylinder through the extrusion force of the reset spring. By starting the motor 54 drives the second gear 53 to rotate, and the second gear 53 drives the first gear 52 to rotate, so that the first gear 52 drives the detection part 55 to rotate, and the roller 554 rotates and moves along the outer wall of the cylinder. If any angle in the cylinder fails to fit with the telescopic abutment plate 43, the friction between the roller 554 and the outer wall of the cylinder will be different. At this time, the resistance sensor 555 will collect data transmission, so that it can be processed or detected. Finally, the upper mold 1 and the lower mold 2 are stamped, and the punch head 6 stamps the cylinder to achieve an S-shaped bending effect at the end of the cylinder.
