[0027] Specific implementation method one: See Figures 1-7This embodiment is described in detail. The internally insertable, segmented hollow product injection mold described in this embodiment specifically includes two symmetrically arranged molding molds and symmetrical shovel bases 7, connected by the symmetrical shovel bases 7. The molding mold includes a fixed mold core 2, a moving mold core 3, several inclined ejector rods 4, several lateral inclined ejectors 19, and an inclined ejector fixing seat 21. The fixed mold core 2 and the moving mold core 3 are engaged vertically. The moving mold core 3 contains a lateral core puller 14, a lateral core puller 26, a shovel base guide bar 22, a strong release insert 24, an inclined ejector core puller 18, an inclined ejector core puller 29, several internal segmented blocks, and core pull inserts 30. The lateral core puller 14 and the lateral core puller 26 are connected. The lower ends of several inclined ejector rods 4 are hinged to the inclined ejector fixing seat 21 via an inclined ejector rod rotation shaft 5.

[0028] The side core pull 14 is provided with an inclined T-shaped guide groove, and the corresponding fixed mold core 2 is provided with an inclined T-shaped guide rail. When the mold is opened, under the action of the core pull bracket 141 on the strong release insert 24, the side core pull 14 remains stationary until the side core pull 14 disengages from the core pull bracket 141, thus completing the side core pull.

[0029] The symmetrical shovel base 7 is similar to a T-shaped structure. The lower half of the T-shaped structure is a wedge-shaped structure. The surfaces on which the two sliders 8 connect with the symmetrical shovel base 7 are inclined surfaces, and they slide through the T-shaped guide rails and guide grooves. When the pull rod 9 is pulled down, the pull rod 9 drives the slider seat 43 to move down, and the slider seat 43 drives the two sliders 8 to move down. Under the action of the T-shaped guide groove on the wedge-shaped structure of the lower half of the symmetrical shovel base 7, the two sliders 8 gradually move closer to the middle, and under the action of the sliders 8, the lateral core puller 16 is pulled out from the moving mold core 3.

When the moving mold core 3 moves downward, the plurality of inclined ejector rods 4 connected to the inclined ejector core puller 29 swing outward through the inclined ejector guide block 13, causing the inclined ejector core puller 29, the core puller insert 30 and the molding part 31 to move obliquely downward away from the plurality of internal segment blocks under the action of the T-shaped guide groove provided on the shovel base guide bar 22; the forced release insert 24, the inclined ejector core puller 28 and the plurality of internal segment blocks move directly downward and follow the moving mold core 3 out.

[0031] The end of the second side core puller 16 is provided with a second side core puller insert 25 for forming the product 18; when the slider 8 drives the second side core puller 16 to be pulled out laterally from the inside of the mold, the second side core puller insert 25 is pulled out along with the second side core puller 16.

[0032] The plurality of internal flaps include internal flap 1 27, internal flap 2 32, internal flap 3 35, and internal flap 4 36. The upper end of internal flap 1 27 is positioned and connected to internal flap 2 32 via a central pin 26. A T-shaped guide groove 2 38 is also provided between internal flap 1 27 and internal flap 2 32. The front end of internal flap 2 32 is slidably connected to internal flap 3 35 via T-shaped guide groove 1 37, and the rear end is slidably connected to internal flap 4 36 via T-shaped guide groove. A fixed mold reference block 33 is provided at the upper end of internal flap 2 32, a horizontal sliding key 2 42 is provided at the upper end of internal flap 2 32, a horizontal sliding key 1 41 is provided at the upper end of internal flap 4 36, and a horizontal sliding groove 40 is provided at the lower end of fixed mold reference block 33.

[0033] The moving mold core 3 is also provided with a molding part 31, which is set on the core puller 30 and cooperates with the internal segment assembly 32, internal segment assembly 35 and internal segment assembly 4 to form the product 18; when demolding, the molding part 31 moves obliquely downward along with the core puller 30.

[0034] The side core-pulling part 14 is provided with a top molding insert 34 for molding the product 18.

[0035] A moving mold heat dissipation plate 10 is provided on the several lateral inclined tops 19 at the positions corresponding to the strong removal inserts 24.

[0036] The fixed mold core 2 is provided with several fixed mold water channels 1 to conduct heat out of the fixed mold core 2; the side inclined ejector fixed seat 44 is provided with a slider cooling water channel 6, which leads to the side inclined ejector 19, and cooperates with the moving mold heat dissipation plate 10 to transfer the heat out of the moving mold core 3; one of the inclined ejector rods 4 on one side edge is provided with a slider cooling water inlet pipe 11, and the other inclined ejector rod 4 on the opposite side edge is provided with a slider cooling water outlet pipe 12. Cooling water enters the inclined ejector rod 4 from the slider cooling water inlet pipe 11 and flows inside the several inclined ejector rods 4 to carry out the heat inside the moving mold core 3, and finally flows out from the slider cooling water outlet pipe 12.

[0037] The moving mold core 3 is also provided with a wedge block 15, which is located between the symmetrical shovel base 7 and several internal segment blocks. The wedge block 15 moves in the same direction as the mold closing direction. When the mold is closed, the wedge block wedges the segment blocks.

[0038] The strong release insert 24 is also provided with a strong release buckle 39. After the core of other molded parts is pulled out, the product can be removed from the strong release insert 24 by utilizing the elasticity of the product.

[0039] The symmetrical shovel base 7 is also provided with a flow channel solidified material 23. The moving mold core 3 is also provided with a bottom core pull 17.

[0040] The specific demolding process of the internally inserted, segmented hollow product injection mold described in this invention is as follows:

[0041] Pulling the pull rod 9 causes the slider seat 43 to move, which in turn causes the slider 8 to slide. Under the action of the symmetrical shovel base 7, the slider 8 slides along the T-shaped guide groove of the lower half of the symmetrical shovel base 7 towards the centerline, thereby causing the side core puller 14 and the side core puller 26 to be pulled out from the mold. The moving mold core 3 moves downward, and when it passes the inclined ejector guide block 13, the outer inclined ejector rod 4 flips outward, thereby causing the inclined ejector core puller 29, the core puller insert 30, and the molded part 31 to move obliquely downward together under the action of the shovel base guide bar 22. At the same time, the inclined ejector core puller 18 and several internal petal blocks... Together with the strong ejector insert 24, it moves downward along with the moving mold core 3 and detaches from the moving mold core 2; after complete detachment, the product 18 and several internal segment blocks are removed together, the fixed mold reference block 33 is removed, and the internal segment block 4 36 slides obliquely downward along the T-shaped guide groove that mates with the internal segment block 2 32; the center pin 26 is removed from the internal segment block 2 32; the internal segment block 1 27 is moved horizontally along the T-shaped guide groove 2 38; the internal segment block 2 32 is moved along the direction of the T-shaped guide groove 1 37, and finally the internal segment block 3 35 is removed to complete the demolding of the product 18.

[0042] In summary, the internal insert type hollow product injection molding mold described in this invention overcomes the problem of difficult internal molding of hollow structure products. By decomposing the internal insert into several parts and disassembling them outside the mold, the internal molding of the product is achieved. Furthermore, the T-shaped sliding grooves set between the various components enable the automatic detachment of each component when the mold is demolded.
