DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.
[0030] Please refer to Figures 1-6 The present application provides an injection mold ejector mechanism, which comprises an injection part 2 and an ejector mechanism 3.
[0031] The ejector mechanism 3 comprises an ejector seat 31 and a T-shaped slide rail 32 rotatably connected to one side of the ejector seat 31, and the arc-shaped groove 311 is formed in the ejector seat 31 around its axis. The limiting piece 36 is arranged on the T-shaped slide rail 32 and can pass through the arc-shaped groove 311 and be fixed to the ejector seat 31. The slide block 34 is slidably arranged in the T-shaped slide rail 32. The ejector rod 35 is rotatably connected to the slide block 34. The ejector block 38 is detachably installed on the top end of the ejector rod 35 and clamped to the undercut of the injection part 2.
[0032] In the embodiment, according to Figures 1-3 the three different shapes of the injection part 2 undercut shape shown in the figure, the specific position of the T-shaped slide rail 32 on the front side of the ejector seat 31 is adjusted and positioned by the cooperation of the limiting piece 36 and the arc-shaped groove 311, and the ejector block 38 of the corresponding shape is installed on the ejector rod 35. This design can flexibly adjust the state of the ejector mechanism 3 to adapt to the undercut of the injection part 2 of various shapes, so that the replacement and use cost of the ejector mechanism 3 is reduced.
[0033] Please refer to Figures 5-6 The rotation shaft 33 is rotatably connected to the axis of the ejector seat 31. One end of the rotation shaft 33 is fixed to the T-shaped slide rail 32. The opposite surface of the T-shaped slide rail 32 and the ejector seat 31 is also movably attached. Specifically, the design of the rotation shaft 33 can freely adjust the position of the T-shaped slide rail 32 on the front side of the ejector seat 31.
[0034] Please refer to Figures 5-6The limiting member 36 includes a locking bolt A361 screwed onto the outside of the T-shaped slide rail 32. The shaft of the locking bolt A361 passes through the arc-shaped groove 311 and is connected to a locking nut A362 that abuts against the other side of the inclined top seat 31. Specifically, once the position of the T-shaped slide rail 32 is determined, the locking bolt A361 is screwed into the T-shaped slide rail 32 and passes through the arc-shaped groove 311 to be fixed with the locking nut A362, thereby positioning the T-shaped slide rail 32.
[0035] It should also be noted that the surfaces of the inclined top seat 31 and the T-shaped slide rail 32 can be glued with rubber pads in actual applications to increase the stability of the positioning of the limiting member 36.
[0036] Please see Figure 5 , Figure 8 The slider 34 is provided with a rotating part A37, and the rotating part A37 realizes the rotational connection between the inclined rod 35 and the slider 34.
[0037] The rotating component A37 includes a double-ended stud 371 screwed onto the slider 34. A through hole is opened at the bottom of the inclined push rod 35 for fitting into the middle of the double-ended stud 371, and a locking nut B372 is screwed onto the outer end of the double-ended stud 371 to limit the movement of the inclined push rod 35. Specifically, one end of the double-ended stud 371 is first screwed onto the slider 34, then the inclined push rod 35 is fitted into the middle of the double-ended stud 371 through its through hole, and finally the locking nut B372 is screwed onto the other end of the double-ended stud 371, thus facilitating the replacement of the inclined push rod 35.
[0038] See Figure 4 , Figure 7 The opposing surfaces of the inclined ejector block 38 and the inclined ejector rod 35 are both horizontally designed, and a screw 39 is fixed to the bottom end of the inclined ejector block 38. A screw hole A that matches the screw 39 is opened on the top end of the inclined ejector rod 35. Specifically, the inclined ejector block 38 and the inclined ejector rod 35 can be detachably connected by the screw 39 and the screw hole A, which makes it convenient to replace different inclined ejector blocks 38 according to different undercut shapes of the injection molded part 2.
[0039] One side of the inclined block 38 and one side of the inclined rod 35 are on the same inclined plane.
[0040] See Figures 4-6 The injection mold inclined ejector slider mechanism also includes injection mold component 1;
[0041] The injection mold member 1 comprises a mold base 11 and a ejector plate 12 movably arranged on the mold base 11 and connected with the bottom end of the inclined ejector seat 31, the bottom end of the mold base 11 is provided with an electric push rod 13 capable of moving through the mold base 11 and being fixed with the bottom end of the ejector plate 12, the upper surface of the mold base 11 is fixed with two mold feet, the top ends of the two mold feet are jointly fixed with a lower mold 14, the lower mold 14 is provided with a guide hole 141 matched with the inclined ejector rod 35, the inner cavity of the lower mold 14 is provided with a core 15, and the core 15 is provided with a avoiding cavity matched with the inclined ejector block 38 and the injection part 2. Specifically, the electric push rod 13 is started to push the ejector plate 12 upward, at this time, the inclined ejector seat 31 located at the upper part of the ejector plate 12 drives the inclined ejector rod 35 to move upward along the guide hole 141, and at the same time, the slider 34 at the bottom of the inclined ejector rod 35 moves to the left along the T-shaped slide rail 32, so that the inclined ejector block 38 is separated from the undercut.
[0042] It should be noted that in actual application, an opening matched with the electric push rod 13 needs to be designed on the external bearing platform on which the mold base 11 is placed, so as to facilitate the use of the present application; or the height of the two mold feet of the injection mold of the present application is increased, the electric push rod 13 is installed at the bottom of the lower mold 14, and the movable end thereof is fixed to the ejector plate 12.
[0043] The upper surface of the inclined ejector seat 31 is movably inserted with locking bolts B at both ends, and the two sides of the ejector plate 12 are provided with screw holes B matched with the locking bolts B. Specifically, the locking bolts B and the screw holes B are matched to facilitate the detachable fixation of the inclined ejector seat 31 on the ejector plate 12.
[0044] When the present application is used:
[0045] The electric push rod 13 is started to push the ejector plate 12 upward, at this time, the inclined ejector seat 31 located at the upper part of the ejector plate 12 drives the inclined ejector rod 35 to move upward along the guide hole 141, and at the same time, the slider 34 at the bottom of the inclined ejector rod 35 moves to the left along the T-shaped slide rail 32, so that the inclined ejector block 38 is separated from the undercut;
[0046] When a new core 15 is needed to be replaced to inject, for example, Figure 2 and Figure 3When the injection molding part 2 in the injection molding machine 1 is changed, the unmatching inclined ejector block 38 is unscrewed from the inclined ejector rod 35 and the new matching inclined ejector block 38 is screwed on. After the T-shaped slide rail 32 is adjusted by unscrewing and tightening the locking nut A 362, the T-shaped slide rail 32 is positioned by the cooperation of the locking nut A 362 and the locking nut A 362. After the new core 15 is installed, the inclined ejector rod 35 is inserted from the corresponding avoiding cavity and guiding hole 141, and the inclined ejector rod 35 is fixed by the double-headed stud 371 and the locking nut B 372. Then the inclined ejector seat 31 is fixed to the ejector pin plate 12. The design can flexibly adjust the state of the inclined ejector mechanism 3 to adapt to the undercut of injection molding parts 2 of various shapes, so that the replacement or use cost of the inclined ejector mechanism 3 is reduced.
[0047] It is apparent to those skilled in the art that the application is not limited to the details of the foregoing exemplary embodiments, and that the application can be implemented in other specific forms without departing from the spirit or essential characteristics of the application.
