[0027] The base plate 4 has a lower mold 1, and an embedded part support seat 5 is vertically arranged in the lower mold 1 in the middle of the base plate 4.

[0028] The base plate 4 has an inclined mold 6 on the upper side.

[0029] The mold frame 3 has a left connecting plate 7 and a right connecting plate 8 respectively located on the two side surfaces of the upper mold 2 and fixed to the upper mold 2, and the upper mold 2 is positioned in the mold frame 3 through positioning pins.

[0030] The positioning pins are 3mm higher than the installation plane of the upper mold 2 and the mold frame 3.

[0031] The top surfaces of the left connecting plate 7 and the right connecting plate 8 are flush with the top surface of the upper mold 2.

[0032] Based on the above, the present application also provides a special-shaped adapter integrally formed method; the following steps are adopted:

[0033] ① Installation: fixedly connect the mold frame 3 and the base plate 4, and sequentially assemble the lower mold 1, the embedded part support seat 5 and the inclined mold 6 in the cavity of the mold frame 3;

[0034] ② Pre-buried: place the metal embedded part 11 on the embedded part support seat 5;

[0035] ③ Bonding: bond and fix the polytetrafluoroethylene film 13 on the inner top surface of the upper mold 2, and then install the upper mold 2 on the left connecting plate 7 and the right connecting plate 8;

[0036] ④ Foaming: add foaming material into the cavity, close the upper mold 2, and screw the screw rod 9 into the mold frame 3 to press the upper mold 2 tightly on the mold frame 3;

[0037] ⑤ Molding: after foaming is completed, sequentially take out the screw rod 9 and the upper mold 2, knock the bottom surface of the base plate 4 to take out the adapter, rotate and take out the embedded part support seat 5 to obtain the formed adapter.

[0038] In step 1, the mold frame 3 and the bottom plate 4 are fixed and placed on a flat level surface.

[0039] In step 4, the screw rod 9 is screwed in by the handle 10.

[0040] Example 1

[0041] Using the above scheme, the specific operation process is as follows:

[0042] First, before the mold foaming, the bottom plate 4 and the mold frame 3 are bolted together and placed on a flat surface, and the lower mold 1, the embedded part support seat 5, and the inclined mold 6 are assembled into the cavity of the mold frame 3 in the order of installation and connection, and are in contact with the bottom plate 4. The metal embedded part 11 is placed on the embedded part support seat 5 as shown in the figure.

[0043] Secondly, the polytetrafluoroethylene film 13 is slightly adhered and fixed to the upper mold 2 guide rail groove surface, and is placed on one side after being bolted and connected with the left and right connecting plates 7 and 8 respectively. The upper mold 2 is set to be higher than the positioning plane 3 by 3 mm, the foaming material is added into the cavity, the upper mold 2 is quickly closed, the screw rod 9 is screwed into the threaded hole by the handle 10, and the upper mold 2 is pressed tightly onto the upper surface of the mold frame 3.

[0044] Finally, after the mold foaming is completed, the screw rod 9 is loosened and removed, the left and right connecting plates 7 and 8 are lifted in the direction perpendicular to the top surface of the upper mold 2, the bottom surface of the bottom plate 4 is tapped with a tool at the mold hole, the adapter is slowly taken out, and then the embedded part support seat 5 is rotated and taken out to obtain a complete adapter. The adapter base 12 is further processed to complete the processing.

[0045] Therefore, the top surface of the upper mold is designed to be parallel to the adapter guide rail groove plane, the top surface of the mold is not parallel to the bottom surface, the embedded part support seat is used to realize the overall molding of the adapter metal embedded part and the adapter base, which ensures the functional requirements of the adapter and improves the use performance; when the mold is lifted, the upper mold is lifted in a direction of an inclined angle; the polytetrafluoroethylene film is adhered to the upper mold guide rail groove cavity surface to ensure the integral molding with the adapter base during foaming; the installation positioning pin of the upper mold and the mold frame is only 3 mm higher than the installation plane, which not only ensures the positioning requirements, but also meets the design of inclined mold lifting.
