Detailed ways

The structural scheme and working process of the utility model are further illustrated in conjunction with examples.

As shown in Figure 1 and Figure 2, a four-lobe side core-pulling plastic injection mold includes a movable mold seat plate 1, a cushion block 2, a supporting plate 3, a punch fixing plate 4, an inclined guide column 5, and a pusher plate 6. Inclined slider 7, wedge block 8, fixed mold seat plate 9, fixed mold plate 10, side core fixed plate 11, side core 12, sprue sleeve 13, positioning ring 14, water pipe 15, punch 16, Slider guide plate 17, fixed plate 18, push plate 19, pusher plate guide sleeve 20, guide post 21, upper guide sleeve 22, guide post 23, lower guide sleeve 24, push rod 25. The punch fixing plate 1 is fixed on the movable mold base plate 1 with bolts through the support plate 3 and the cushion block 2, and the four guide columns 21 and the four inclined guide columns 5 are fixed on the support plate 3 through the punch fixing plate 4, 4 One inclined slider 7 is arranged in the slider guide plate 17 on the pusher plate 6, and four slider guide plates 17 are respectively fixed on the pusher plate 6 by screws. The four slanted sliders are respectively arranged on the four slanted guide posts 5 , and the slanted sliders 7 can slide in the slanted guide posts 5 . As shown in Figure 3, the side cores adopt an inlaid structure, that is, a four-petal side core-pulling plastic injection mold, and 55 side cores 12 for each petal are respectively installed in four side core fixing plates 11, and the four side molds Core fixing plate 11 is fixed on the inboard of 4 inclined sliders 7 with screws respectively. The inner sides of the side core fixing plates 11 are semicircular, and the inner sides of the four side core fixing plates 11 form a cylinder. Not only the structure is simple, but also the replacement and maintenance are convenient. The fixed template 10 is fixed on the fixed template seat plate 9 with screws, the punch 16 is fixed on the supporting plate 3 through the punch fixing plate 4, the sprue sleeve 13 is set in the fixed template 10 through the positioning ring 14, and the four wedge blocks 8 is fixed on the side of the fixed formwork 10 with screws, and the pusher plate 6 and the fixed formwork 10 are arranged on the four guide posts 21 through 4 pusher plate guide sleeves 20 and 4 upper guide sleeves 22 respectively, and the guide posts 21 can be The push plate guide sleeve 20 and the upper guide sleeve 22 slide inside, and the two guide posts 23 are arranged on the fixed plate 18 and the push plate 19 through the lower guide sleeve 24, the guide posts 23 can slide in the lower guide sleeve 24, and the four push rods 25 is fixed on the pusher plate 19 through the fixed plate 18, the push rod 25 is fixedly connected with the pusher plate 6 with screws, the water pipe 15 is arranged in the inner cavity of the punch 16, and is fixed on the support plate 3 for passing in cooling Water cooled punch.

The working process of the utility model is: the core of the mold adopts a four-lobe side core-pulling structure. When parting, the inclined guide column 5 and the inclined slider 7 move downward together with the movable mold seat plate 1, and the fixed template 10 and the sliding mold The block guide plate 17 is split, when the inclined slider 7 and the side core fixing plate 11 are disengaged from the groove of the fixed template 10, the inclined guide column 5 forces the inclined slider 7 to move sideways to pull the core, and the side core 12 core is pulled. At this time, the demoulding mechanism starts to promote the movement of the pusher plate 19, and the push rod 25 promotes the pusher plate 6 to complete the demoulding of the plastic part.
