Detailed description of the invention

Shown in Fig. 3, embodiment is described further.

A kind of plastics extrusion die disclosed in the utility model, comprise plastics extrusion die body 19 and support 18, described support 18 is provided with the support column 1 for supporting plastic extrusion die body 19, chute 2 is provided with in described support column 1, be provided with the slide block 3 that can slide up and down in described chute 2, be provided with limited block 8 in described chute 2, described slide block 3 is provided with the groove 9 matched with limited block 8, slide block 3 is moved up along specific track, can not offset.

As shown in Figure 1, described plastics extrusion die body 19 is fixedly connected with support bar 15, described support bar 15 is worn and is penetrated on slide block 3, described support bar 15 is positioned at the center of slide block 3, make the top and bottom of slide block 3 being of uniform thickness to support bar 15, overall structure is more firm, moves up and down with the support bar 15 in movable slider 3 by moving up and down slide block 3, meanwhile, also just corresponding to the plastics extrusion die body 19 that support bar 15 is fixedly linked oscilaltion.

As shown in Figure 1, described slide block 3 is fixedly connected with screw rod 5, the length of described screw rod 5 is greater than the length of chute 2, prevent because screw rod 5 is too short, when slide block 3 drops to a certain degree time, screw rod 5 and nut 4 are separated, slide block 3 directly drops to bottom, the top of described support column 1 is provided with limiting plate 6, the center of described limiting plate 6 is provided with wears for screw rod 5 perforated hole 7 penetrated, described screw rod 5 is provided with the nut 4 matched with screw rod 5, described nut 4 is conflicted mutually with the upper surface of limiting plate 6, by the cooperation of nut 4 and screw rod 5, convert rotary motion to linear movement, due to the conflict of limiting plate 6, screw rod 5 is moved up, drive the slide block 3 be fixed on slide bar.

As shown in Figure 1, described screw rod 5 comprises the first half 10 and Lower Half 11, the hand of spiral of described Lower Half 11 is contrary with the hand of spiral of the first half 10, described nut 4 is threaded with the first half 10 of screw rod 5, the Lower Half 11 of described screw rod 5 is threaded with slide block 3, if the first half 10 of screw rod 5 is consistent with Lower Half 11 hand of spiral, when rotating nut 4 time, may occur that nut 4 is greater than the frictional force of slide block 3 and screw rod 5 Lower Half 11 with the frictional force of screw rod 5 first half 10, make nut 4 and screw rod 5 geo-stationary, and slide block 3 and screw rod 5 rotate and make screw rod 5 skid off from slide block 3 and cannot be elevated, and the hand of spiral of the first half 10 and Lower Half 11 is contrary, when rotating screw cap because the first half 10 and Lower Half 11 screw thread are contrary and slide block 3 is limited in that limited block 8 can not occur in skew makes screw rod 5 to rotate, nut 4 is better rotated.

As shown in Figure 2, the two ends, left and right of described limiting plate 6 are equipped with fixed block 12, the top of described support column 1 is provided with the resettlement groove 13 settled for fixed block 12, described fixed block 12 removably connects with support column 1, described fixed block 12 is bolted with support column 1, when mounting limit plate 6 time, first the fixed block 12 on limiting plate 6 is embedded in resettlement groove 13, the screw on the screw on limiting plate 6 and support column 1 is facilitated to align, improve the operating efficiency of operating personnel, resettlement groove 13 also has spacing effect simultaneously, prevent from operating personnel when rotating nut 4 because the frictional force between nut 4 and limiting plate 6 makes limiting plate 6 produce to offset.

As shown in Figures 1 to 3, described screw rod 5 is arranged with pad 14, described pad 14 is between nut 4 and limiting plate 6, the area of described pad 14 is greater than the area of nut 4, with the lifting surface area with increase limiting plate 6, prevent because nut 4 area is too little, the pressure that limiting plate 6 is subject to is too large, the weight of plastics extrusion die body 19 cannot be sustained, thus make limiting plate 6 rupture.

As shown in Figures 1 to 3, described support column 1 is provided with scale 16, the position pointing to scale 16 by the lower edge of slide block 3 shows the adjustable height of height that slide block 3 is elevated both plastics extrusion die body 19, by measuring the difference in height drawn between plastics extrusion die body 19 and fuselage, according to the difference in height measured, slide block 3 is made to be elevated identical numerical value, can be more accurate by scale 16, guarantee that plastics extrusion die and fuselage are in sustained height.

As shown in Fig. 1 to 2, described limiting plate 6 is provided with oil filler point 17, described oil filler point 17 is connected with perforated hole 7, screw rod 5 is in the process of rotating, lubricating oil flows to screw rod 5 surface from oil filler point 17, and what screw rod 5 was rotated is more smooth and easy, does not have card and feel immediately in the process that slide block 3 is elevated, also can prevent screw rod 5 from getting rusty simultaneously, cause slide block 3 to be elevated.

When operating personnel need to dock plastics extrusion die body 19 and fuselage time, first measure the height of fuselage to ground, measure the distance of plastics extrusion die body 19 to ground again, both differences in height are exactly the distance that plastics extrusion die body 19 needs lifting, rotating nut 4, makes slide block 3 slowly be elevated, when the position of the lower edge of slide block 3 is in scale 16 position of needs, stop the rotation nut 4, docked by plastics extrusion die body 19 with fuselage.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
