Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1-4, a limiting structure for preventing iron parts from moving up and down comprises a rear template 1, a rear mold core 2, mold feet 3, a fixing plate 4, an upper ejector plate 5 and a lower ejector plate 6, a first insert 7 is arranged in the middle of the rear template 1, a second insert 8 is arranged on the first insert 7, a third insert 9 is fixedly connected in the second insert 8, a positioning groove 701 and a placing hole 702 are arranged in the first insert 7, the placing hole 702 is internally threaded with a bead screw 10, the second insert 8 and the third insert 9 are in hollow stepped column shapes, an iron thimble 12 is arranged between the upper thimble plate 5 and the lower thimble plate 6, a plurality of plastic thimbles 11 are arranged beside the iron thimble 12, the iron part thimble 12 is slidably connected with the first insert 7, and the plastic part thimble 11 is slidably connected with the first insert 7 and the second insert 8.
The first insert 7 is in threaded connection with the rear template 1, and the second insert 8 is in threaded connection with the first insert 7.
The second insert 8 and the third insert 9 are coaxially arranged, and the plastic ejector pins 11 are distributed in an annular array along the iron ejector pin 12.
The positioning groove 701 and the mounting hole 703 are both communicated with the placing hole 702, and the second insert 8 is located in the rear mold core 2.
The working principle of the utility model is as follows: when the utility model is used, firstly, an iron piece 13 is placed into the placing hole 702 along the third insert 9, the iron piece 13 is rotated and pressed downwards to be attached to the positioning groove 701, after the iron piece 13 is placed, the bead screw 10 clamps the groove on the iron piece 13 to realize up-and-down positioning, then the injection molding machine is used for closing the mold and completing injection molding, the injection molding machine is used for opening the mold and ejecting, the iron piece 13 is ejected upwards by the iron piece ejector pin 12, the ejecting force of the iron piece ejector pin 12 is greater than the bead retreating force of the bead screw 10, and therefore, a product is ejected smoothly.
The above examples are intended to further illustrate the present invention, but are not intended to limit the utility model to these specific embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
