The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 2, Fig. 3 and Fig. 4, the utility model inserts mould comprises a cover half (figure does not show), a dynamic model, a slide block die 20, location slide block 30 and some pilot pins; In the present embodiment, each pilot pin comprises two vertical pilot pin 41 and two horizontal tracing needles 42, and this horizontal tracing needle 42 has holding section 421.

This cover half is provided with Angle Pin (figure does not show).

The corresponding setting with cover half of this dynamic model comprises a moving platen (figure does not show) and a mavable module core 11 that is fixed on this moving platen; This mavable module core 11 comprises one first mavable module core 111, one second mavable module core 112, one the 3rd mavable module core 113 and one the 4th mavable module core 114; Wherein, the vertical location pin hole 1112 that offers a storage tank 1111 on first mavable module core 111 and be communicated with this storage tank 1111; Second and third mavable module core 112,113 is established a die through hole 1121 altogether.

This slide block die 20 is installed on the moving platen slidably, has base portion 21, forming part 22 and sliding power portion 23, offers two on the base portion 21 and dodges hole 211, offers one first Angle Pin hole 231 in the sliding power portion 23.

This positioning sliding block 30 is oppositely arranged with slide block die 20, is installed in slidably on the moving platen, is provided with the second Angle Pin hole 31 and two horizontal location pin holes (figure does not show), and described horizontal tracing needle 42 is fastened in the horizontal location pin hole.

During assembly jig, earlier four mavable module cores 111,112,113,114 are combined into mavable module core 11, constitute a die through hole 1121; Storage tank 1111 is inserted and extend into to vertical pilot pin 41 from vertical location pin hole 1112; Place slide block die 20 again, make and dodge that hole 211 is sheathed on vertical pilot pin 41 upper ends, slide block die 20 base portions 21 are placed in storage tank 1111 and the die through hole 1121 movably; Place inserts 80 at last, make horizontal part 81 holes 801 covers of inserts 80 be held in vertical pilot pin 41 tops.

See also Fig. 5 and Fig. 6, during matched moulds, Angle Pin is inserted in respectively in the second Angle Pin hole 31 of the first Angle Pin hole 231 of slide block die 20 and positioning sliding block 30, thereby make positioning sliding block 30 be resisted against inserts 80 vertical portions 82 1 sides, wherein horizontal tracing needle 42 passes hole 801 and the position of inserts 80 is further fixed; The forming part 22 that makes slide block die 20 is drawn close and is formed die cavity (figure does not show) jointly with positioning sliding block 30, mavable module core 12 and cover half to inserts 80.

See also Fig. 7 and Fig. 8, during the demoulding, cover half separates up and down with dynamic model; Under the effect of Angle Pin, slide block die 20 withdraws from working of plastics 90 grooves 91, positioning sliding block 30 drives the hole 801 that horizontal tracing needle 42 withdraws from inserts 80.

As mentioned above, the utility model inserts mould cooperates with vertical pilot pin 41 by the hole 211 of dodging of slide block die 20, thereby under the situation that does not influence 41 work of vertical pilot pin, slide block die 20 is cooperated with cover half and dynamic model and form groove 91 structures, that guarantees to produce carries out smoothly.
