Detailed description of the invention
Below in conjunction with accompanying drawing, describe the specific embodiments of the support in a kind of hollow extrusion die described in the utility model in detail:
As Fig. 1, shown in Fig. 2 and Fig. 3, support in a kind of hollow extrusion die, comprise: for installing the core seat 3 of inner side core, and for installing the annular canister die holder 1 of outer side neck mould, core seat 3 overlaps with the axial line of annular canister die holder 1, connected together by the some spokes be circumferentially evenly arranged 2 between core seat 3 and annular canister die holder 1, the number of spoke 2 can be determined according to actual conditions such as the sizes of support, as shown in Figure 4, the bottom of spoke 2 the both sides of circumferential direction by inner and be disposed with outward adjacent in inclined-plane 21 and outer inclined-plane 22, in, outer inclined-plane 21 and 22 towards the opposite, form " V " font staggered, and, in, outer inclined-plane 21 is all identical with gradient with the width of 22, in so-called inclination angle refers to, angle between outer inclined-plane 21 and 22 and the respective side of spoke 2, this angle is between 30 ~ 60 °, the top of spoke 2 offers elongated water conservancy diversion inclined-plane 23 respectively in the both sides of circumferential direction, and the angle between this pair water conservancy diversion inclined-plane 23 is usually between 45 ~ 75 °.In the present embodiment, the upper and lower end face of described annular canister die holder 1 is respectively arranged with annular boss 12 near interior along place, annular canister die holder 1 is circumferentially evenly provided with several and installs through hole 11, described core seat 3 comprises: inner core 31 and screw rod 34, several described spokes 2 are connected with the periphery wall of inner core 31, the top of inner core 31 is provided with inside drum cover 311, inside drum cover 311 is provided with conically shaped 32, the center of inside drum cover 311 offers the assembling screwed hole coordinated with screw rod 34, the through inside drum cover 311 of assembling screwed hole, the top of conically shaped 32 is provided with cone cover 321, cone cover 321 offers the assembling through hole coordinated with screw rod 34, described screw rod 34 is located in the assembling screwed hole of inside drum cover 311 and the assembling through hole of cone cover 321, and stretch out from the assembling through hole of cone cover 321, revolve and be located at the taper matched with conically shaped 32 and tighten up in nut 35.
The operation principle of support described in the utility model is: the fluid of melting flows down along a pair water conservancy diversion inclined-plane 23 (angle of flare) at spoke 2 top, when flowing through inside and outside inclined-plane 21 and 22, fluid is made to change flow direction in the circumferential, then, again through the compression of follow-up plug and mouth mould, change the flow direction of described fluid diametrically, the fluid chemical field of melting is obtained more even, thus there is no weld mark on the final plastic product formed.
