[0001] The invention relates to the technical field of automatic assembly machinery for electromagnetic valves, and in particular to an assembly molding mechanism for a valve core body and a valve body of an electromagnetic valve. Background Art

[0002] The main components of the solenoid valve are the valve core and the valve body. During assembly, the valve core needs to be inserted into the valve body and fixedly connected to the valve body through a flange. During assembly, an O-ring needs to be set on the valve core and then installed into the valve body. Since the solenoid valve involves many parts and a complex structure, the assembly of the various parts of the solenoid valve is still mostly done manually. Only a limited number of links are assembled using automated production equipment. The processing efficiency is low, and the accuracy of the solenoid valve is difficult to guarantee. The yield rate of the solenoid valve is not high, which makes the processing cost of the solenoid valve high. Summary of the invention

[0035] The assembly molding mechanism of the present invention comprises a feeding track 3, an O-ring installation unit, a valve core body pressing unit and a flange installation unit. A feeding tray 31 is arranged on the feeding track 3, and a plurality of valve core bodies 11 are placed on the feeding tray 31. The housing 111 of the valve core body placed on the feeding tray 31 is at the bottom and the sleeve 112 is at the top.

[0036] See attached Figure 7 As shown, the O-ring installation unit of this embodiment includes three O-ring installation stations, each of which is provided with an O-ring supply tray 41, an O-ring sleeve connecting rod 42 that can swing toward or away from the O-ring supply tray 41, and a first rotating cylinder 43 for driving the O-ring sleeve connecting rod 42 to rotate. The O-ring sleeve connecting rod 42 of the present invention includes a center rod 421 and a fixed sleeve 422 disposed outside the center rod 421, and the center rod 421 can be telescoped into the fixed sleeve 422. The present invention also includes an ejection cylinder for driving the center rod 421 to telescope. The inner diameter of the fixed sleeve 422 is larger than the outer diameter of the sleeve 112 of the valve core body, and smaller than the outer diameter of the O-ring. Therefore, when the O-ring needs to be connected to the sleeve, the center rod 421 is retracted upward and the fixed sleeve 422 is mounted on the outside of the sleeve of the valve core body. Under the limit of the lower end of the fixed sleeve 422, the O-ring falls off the center rod 421 of the O-ring connecting rod and is stuck on the sleeve of the valve core body.
