[0006] The number of limiting columns is 4, which are respectively located at the four corners of the guide column fixing plate.

[0007] The number of top rods and bushing sleeves is N, where N is an integer greater than or equal to 2.

[0008] The number of steel balls is 3, which are evenly distributed along the circumference of the annular groove.

[0009] The feeding rod and the pull-type handle are both door-shaped structures, and the feeding rod is located inside the pull-type handle.

[0010] The number of limiting bolts is 2.

[0011] The present application provides a kind of bushing placement jig, first adopt bushing sleeve to fix bushing, then use ejector rod to push bushing to injection mold kernel position, place bushing fast and convenient, once put multiple products can be pushed to position, improve productivity work efficiency, it is favorable to assist production, save cost, reduce loss.

[0017] The present application will be further described below in conjunction with the drawings, the following examples are only used to more clearly illustrate the technical scheme of the present application, and cannot limit the protection scope of the present application.

[0018] As Figures 1 to 4 shown, the present application provides a kind of bushing placement jig, including front and rear guide column fixed plate 1 and ejector rod fixed plate 2, guide column fixed plate 1 front is provided with limit column 5 and guide column 7, guide column 7 is used to fix the guide hole position of placement mold, limit column 5 limits the depth of the placed bushing 8 position.The number of limit column 5 is 4, respectively located at the four corners of guide column fixed plate 1.

[0019] Guide column fixed plate 1 and ejector rod fixed plate 2 are movably connected by limit bolt 4, the number of limit bolt 4 is 2.Spring 9 is sleeved on limit bolt 4.Under normal circumstances, under the action of spring 9 elastic force, the distance between guide column fixed plate 1 and ejector rod fixed plate 2 is larger.Guide column fixed plate 1 is vertically provided with bushing sleeve 6, and ejector rod 10 is vertically provided on ejector rod fixed plate 2, and ejector rod 10 extends into bushing sleeve 6.The number of ejector rod 10 and bushing sleeve 6 is N, wherein N is an integer greater than or equal to 2.In the present embodiment, the number of ejector rod 10 and bushing sleeve 6 is 4, which can be used to place four bushings 8 at the same time.

[0020] The annular groove is provided with a plurality of steel balls 11 for fixing the bushing 8 on the outer side of the front end of the bushing sleeve 6, the number of the steel balls 11 is three, and the steel balls 11 are uniformly distributed along the circumference of the annular groove. The annular groove is provided with a circular hole for the steel balls 11 to partially extend into the bushing sleeve 6, and the annular groove is provided with a restraining rubber ring 12, and the steel balls 11 are in contact with the inner ring of the restraining rubber ring 12. The restraining rubber ring 12 acts on the steel balls 11 through the elastic force, and the steel balls 11 play a fixing role on the bushing 8.

[0021] The limiting bolt 4 is connected with a discharging rod 13, and the rear of the ejector rod fixing plate 2 is connected with a pull type handle 3. The discharging rod 13 and the pull type handle 3 are both of a door-shaped structure, and the discharging rod 13 is located on the inner side of the pull type handle 3.
