[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] Example 1:

[0026] See Figure 1-5 A mold core inclined top running-in device for bottle cap production includes a base 10 and a clamping device 20, a reciprocating seat 30 and a driving device 40 installed on the base 10. The clamping device 20 is used to clamp and fix the mold core 50. The reciprocating seat 30 is located on one side of the clamping device 20. The reciprocating seat 30 is provided with two protruding parts on the side close to the clamping device 20. The two protruding parts are located at both ends of the mold core 50 and are used to reciprocate the inclined top on the mold core 50. The driving device 40 is transmission-connected to the reciprocating seat 30. The reciprocating seat 30 reciprocates along the axial direction of the mold core 50 under the drive of the driving device 40. The clamping device 20 is used to clamp and fix the mold core 50. The reciprocating seat 30 can move axially along the mold core 50, and an extension portion is provided on the reciprocating seat 30. The two extension portions are respectively located at both ends of the inclined top on the mold core 50. The reciprocating seat 30 reciprocates along the axial direction of the mold core 50 under the drive of the driving device 40, thereby driving the inclined top to reciprocate in the slide groove of the mold core 50, thereby running-in the mold core and the inclined top.

[0027] See also Figure 3 The clamping device 20 includes a fixing seat and an ejecting device 23. The fixing seat includes a fixing block 21. A fixing rod 22 is mounted on the fixing block 21 on the side facing the ejecting device 23. The telescopic end 231 of the ejecting device 23 is opposite to the fixing rod 22. When the telescopic end 231 of the ejecting device 23 is retracted, the mold core 50 is conveniently placed between the fixing rod 22 and the telescopic end 231 of the ejecting device 23. When the telescopic end 231 of the ejecting device 23 is extended, the mold core 50 is fixed. Figure 5 shown.

[0028] In addition to the above-mentioned structure, the clamping device 20 may also adopt other clamping structures, such as a clamping structure similar to a vise.

[0029] In a preferred solution, the ejection device 23 can be one of an air cylinder, a hydraulic cylinder, and a tail ejection device.

[0030] The tailstock device is a prior art device, for example, a tailstock for fixing workpieces on CNC machine tools disclosed in CN217452156U. When applied to the present application, the tailstock body is mounted on the base 10, and the thimble adopts a flat head structure. By rotating the rotating wheel, the telescopic end 231 can be driven to extend and retract.

[0031] See also Figure 1 、 2 4. In one embodiment, a support plate 11 is mounted on a base 10, a slider 12 is mounted on the support plate 11, a linear slide 13 is slidably connected to the slider 12, and a reciprocating seat 30 is mounted on the linear slide 13. The slider 12 and linear slide 13 are conventional products. This structure enables the reciprocating seat 30 to reciprocate in a directional manner.

[0032] For further information, see Figure 1 The two protruding parts on the reciprocating seat 30 are respectively a first stopper 31 and a second stopper 32, and a locking screw 33 is screwed onto the second stopper 32. The first stopper 31 is a fixed structure, and the second stopper 32 is screwed onto the locking screw 33, which is used to lock the inclined top.

[0033] In this embodiment, see Figure 1 、 4 The drive device 40 includes a reduction motor 41, an eccentric shaft 42, a swing block 43, a bearing 44, and a push-pull rod 45. One end of the eccentric shaft 42 is mounted on the output shaft of the reduction motor 41, and the other end is mounted with the bearing 44. The swing block 43 is mounted on the outer ring of the bearing 44. One end of the push-pull rod 45 is fixedly connected to the swing block 43, and the other end is hinged to the reciprocating seat 30. When the output shaft of the reduction motor 41 rotates, the eccentric shaft 42 rotates. Since the eccentric shaft 42 and the swing block 43 are connected by the bearing 44, the swing block 43 swings, which in turn drives the push-pull rod 45 to push and pull the reciprocating seat 30, causing the reciprocating seat 30 to reciprocate.

[0034] In this embodiment, see Figure 1 The eccentric shaft 42 has two shaft portions, one of which is connected to the swing block 43 and is eccentrically connected to the other shaft portion.

[0035] Specifically, a double-ear seat 14 is installed at the end of the reciprocating seat 30, or the end of the linear slide rail 13, and the push-pull rod 45 is hinged to the double-ear seat 14 through a pivot.

[0036] Of course, in addition to the above structure, the driving device 40 may also adopt one of a pneumatic cylinder, a hydraulic cylinder and an electric push rod.

[0037] The working principle or action process of the utility model is as follows:

[0038] See also Figure 1 、 5 When in use, first install and fix the mold core 50 on the clamping device 20, and make one of the inclined tops face the reciprocating seat 30, and then tighten the locking screw 33 to lock the inclined top.

[0039] Start the reduction motor 41, which drives the eccentric shaft 42 to rotate. Since the eccentric shaft 42 and the swing block 43 are connected by the bearing 44, the swing block 43 is driven to swing, thereby driving the push-pull rod 45 to push and pull the reciprocating seat 30, causing the reciprocating seat 30 to reciprocate, thereby driving the inclined top to reciprocate in the slide groove of the mold core 50, thereby running-in the mold core and the inclined top.
