Detailed Description

The following describes the thermosetting pultrusion die according to the present invention in detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the thermosetting pultrusion die 100 comprises an upper die 1 and a lower die 2, wherein the upper die 1 is provided with array through holes 3, the array through holes 3 are arranged in an array of 2 × 6 to 4 × 16, and the distance between two adjacent array through holes 3 is equal. The number and arrangement of the array through holes 3 are based on the upper die 1 and the lower die 2 which are fastened to achieve thermosetting pultrusion force. The lower die 2 is provided with a corresponding number of screw holes (not shown in the figure) at corresponding positions, and the upper die 1 and the lower die 2 are fastened by matching bolts in the through holes 3 and the screw holes.

A cavity 4 is provided between the upper die 1 and the lower die 2, and the cavity 4 penetrates from one end of the die to the other end. According to the arrangement of through-hole 3, screw on last mould 1 and the lower mould 2, set up die cavity 4 and be 1 to 2, be located last mould 1 between array through-hole 3 and lower mould 2. That is, when the through holes 3 and the screw holes are arranged in two rows, the mold cavities 4 are one, and the through holes 3 and the screw holes are arranged in three rows, the mold cavities 4 are two. The die cavity 4 is designed into a U shape or a round shape and the like according to different extruded profiles.

In order to facilitate and accurately position the upper die 1 and the lower die 2 during installation, a mold clamping pin is arranged in the mold cavity 4, and the shape of the mold clamping pin is matched with that of the mold cavity 4, such as U-shaped, round and other special shapes. The outside diameter of the clamping pin is about 0.005 μm smaller than the inside diameter of the cavity 4. During the cooperation, place the fitting pin in die cavity 4 of lower mould 2 earlier, when will go up mould 1 and set up on lower mould 2, through the fitting pin cooperation location, make the position of going up mould 1 and lower mould 3 correspond, make things convenient for the bolt to go up mould 1 and lower mould 2 and fix a position the locking.

The front end, the middle end and the rear end of the die are respectively provided with a pre-curing heating module 5, a semi-curing heating module 6 and a complete curing heating module 7.
