Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a vertical P-type rubber fabric composite sealing profile molding mold. Background Technology

[0002] Vertical P-type rubber-fabric composite profile is a composite profile with a "P"-shaped cross-section, formed by combining rubber and fabric. It combines the excellent sealing performance of rubber with the high strength and high wear resistance of fabric.

[0003] Vertical P-type rubber-fabric composite profiles have a wide range of applications in the aerospace industry, such as sealing cabin doors, cargo doors, and emergency exit doors. This ensures that the cabin pressure does not leak when the aircraft is cruising, maintains cabin pressurization, and prevents external media such as rain, dust, and hail from entering the aircraft. It also provides sound insulation and heat insulation. This requires the vertical P-type rubber-fabric composite profile to be designed to fit tightly to the door frame, and it must not be torn or permanently deformed under frequent opening and closing and air pressure impacts.

[0004] In the existing molding process of vertical P-type rubber fabric composite profiles, the mold core is not easy to remove, and the product is at risk of deformation and scratches during demolding. In addition, the product is prone to core deviation during production, resulting in low product dimensional accuracy, thereby reducing the product qualification rate and production efficiency.

[0005] Therefore, there is an urgent need for a vertical P-type rubber fabric composite sealing profile molding die that allows for easy removal of the core and prevents product misalignment. Summary of the Invention

[0006] The purpose of this invention is to provide a vertical P-type rubber fabric composite sealing profile molding die, so as to at least solve the problems of the existing mold core being difficult to remove and the product being prone to core deviation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vertical P-type rubber fabric sealing profile molding die includes an upper die, a middle die, a lower die, and a mold core, wherein a cavity is formed between the upper die, the middle die, the lower die, and the mold core; The mold core has a segmented structure, formed by splicing together multiple mold core blocks; A stop block is provided on the front side of the middle mold, and the stop block is set on the lower mold to position and cooperate with the middle mold.

[0008] Furthermore, the mold core has a U-shaped structure.

[0009] Furthermore, the mold core includes two mold core blocks, with one end of each mold core block fitting together and the other end of each mold core block having a plug.

[0010] Furthermore, the plug includes an upper part and a lower part, which clamp the mold core in the middle.

[0011] Furthermore, movable positioning pins are respectively provided at both ends of the mold core near the plug.

[0012] Furthermore, the stop block is fixed to the lower mold by multiple fixing bolts.

[0013] Furthermore, the stop block is positioned and engaged with the middle mold by multiple positioning bolts.

[0014] Furthermore, the middle mold and the lower mold are respectively provided with glue flow grooves on both sides of the mold core.

[0015] Furthermore, the positioning bolts are spaced apart and extend horizontally from the front side of the stop block to the middle mold.

[0016] Furthermore, the fixing bolts and the positioning bolts are arranged vertically and are distributed alternately at intervals.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a vertical P-type rubber fabric composite sealing profile molding mold, which adopts a mold core block design. The mold core includes two mold core blocks that fit tightly together. By removing the mold core blocks, it is easier to remove the mold core, thereby avoiding the risk of product deformation and scratches during demolding.

[0018] 2. This utility model adopts a stop block design. The stop block is set on the front side of the middle mold. The middle mold is positioned and fitted by the stop block. First, the stop block is fixed by the fixing bolts. Then, the middle mold is positioned and fitted by the positioning bolts. After the molding and vulcanization are completed, the positioning bolts are loosened first, and then the middle mold is directly removed from the mold. The middle mold is positioned and fitted by the stop block, which makes it less likely for the product to be misaligned during production, ensuring the dimensional accuracy of the product, and improving the product qualification rate and production efficiency.

[0024] In a specific implementation, Figure 2 The direction shown is defined as the front side.

[0025] Example: This embodiment provides a vertical P-type rubber fabric composite sealing profile molding die, which adopts a core block design and a stop block design, including an upper mold 9, a middle mold 2, a lower mold 1 and a core 4, and a cavity is formed between the upper mold 9, the middle mold 2, the lower mold 1 and the core 4.

[0026] The top of the middle mold 2 and the top of the lower mold 1 are flush with each other and are both in contact with the upper mold 9 above. The lower mold 1 has a U-shaped groove, and the mold core 4 is disposed in the U-shaped groove.

[0027] Specifically, the mold core 4 has a segmented structure, formed by splicing together multiple mold core blocks, and the mold core 4 has a U-shaped structure.

[0028] In this embodiment, the mold core 4 includes two mold core blocks, with one end of each mold core block tightly fitted together and the other end of each block having a plug 5, such as... Figure 3 As shown by the dividing line on the mold core 4, the two mold core blocks are not the same size. In other embodiments, the two mold core blocks may also be the same size.

[0029] The plug 5 includes an upper part and a lower part, which are fixed to the lower mold 1 by rivets. The upper part and the lower part clamp and fix the mold core 4 in the middle for positioning the mold core 4, and at the same time, the plug 5 closes the cavity.

[0030] The mold core 4 is provided with movable positioning pins 3 at both ends near the plug 5.

[0031] In this embodiment, after the molding and vulcanization are completed, the upper mold 9, the middle mold 2 and the plug 5 are disassembled, and the product and the mold core 4 are taken out from the cavity together. Then the mold core 4 is taken out in two separate steps. Taking out the mold core 4 in pieces is more convenient than taking it out as a whole, and avoids the risk of product deformation and scratches during demolding.

[0032] Specifically, a stop block 6 is provided on the front side of the middle mold 2. The stop block 6 is a cuboid and is provided on the lower mold 1 and is flush with the front edge of the lower mold 1. The stop block 6 is used to position and cooperate with the middle mold 2.

[0033] In this embodiment, the stop block 6 is fixed to the lower mold 1 by four fixing bolts 7.

[0034] The fixing bolts 7 are spaced apart, and the fixing bolts 7 extend vertically from the top of the stop block 6 to the lower mold 1.

[0035] In this embodiment, the stop block 6 is positioned and engaged with the middle mold 2 by three positioning bolts 8.

[0036] The positioning bolts 8 are spaced apart, and the positioning bolts 8 extend horizontally from the front side of the stop block 6 to the middle mold 2.

[0037] In this embodiment, the fixing bolt 7 and the positioning bolt 8 are arranged vertically, and the fixing bolt 7 and the positioning bolt 8 are distributed alternately at intervals.

[0038] In this embodiment, the intermediate mold 2 is positioned and engaged by the stop block 6. First, the stop block 6 is fixed by several fixing bolts 7, and then the intermediate mold 2 is positioned and engaged by several positioning bolts 8. After the molding and vulcanization are completed, the positioning bolts 8 are loosened first, and then the intermediate mold 2 is directly removed from the mold. The intermediate mold 2 is positioned and engaged by the stop block 6, which makes it less likely for the product to be misaligned during production, ensuring the dimensional accuracy of the product, and improving the product qualification rate and production efficiency.

[0039] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
