For some diaphragms 300, which are made of single-layer or multi-layer polymer materials, the diaphragm 300 has a relatively flexible structure, which is easily shrunk and deformed after being molded under high temperature and pressure and cooled.
Referring to fig. 1, the mold base 100 in this embodiment includes a base body 110 and a corrugated rim forming portion 120, the corrugated rim forming portion 120 is disposed on an upper surface 101 of the base body 110, preferably, the upper surface 101 is a plane, of course, in some embodiments, the upper surface 101 of the base body 110 may also be a curved surface, and preferably, the corrugated rim forming portion 120 is integrally formed with the base body 110.
Fig. 1-3 illustrate a first embodiment of the present invention, in which the upper surface 101 is a plane, the edge-forming portion 120 includes a first edge 121, a second edge 122 and a corner 123 connecting the adjacent first and second edges, and the first edge in this embodiment has a shorter length than the second edge. The height H of the middle portion of the first side portion 121 relative to the seat body 110 is higher than the height X of the two ends of the first side portion 121 connected to the corner portion 123 relative to the seat body 110, and it should be noted that the height relative to the seat body 110 in this embodiment refers to the height relative to the upper surface 101 of the seat body 110.
In order to realize the technical solution of the present embodiment, there are two solutions, one is to make a height increasing compensation arrangement in the middle of the first edge portion 121, so that the height H of the middle of the first edge portion 121 relative to the seat body 110 is higher than the height X of the two ends of the first edge portion 121 relative to the seat body 110. In the second solution, the two ends of the first edge 121 are respectively provided with a lowering compensation device, for example, two ends of the first edge 121 are provided with a slot, and the like, and the height X of the two ends of the first edge 121 relative to the seat body 110 is lower than the height H of the middle of the first edge 121 relative to the seat body 110.
