[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 The present invention provides a seat foaming mold frame, comprising an upper seat body 11, a lower seat body 12, a locking arm 21, a limiting arm 22, a quick lock buckle 31 and a transfer seat 41. The locking arm 21 and the limiting arm 22 are respectively installed on the upper seat body 11 and the lower seat body 12. The upper seat body 11 and the lower seat body 12 are hinged to each other, the locking arm 21 and the limiting arm 22 are buckled to each other, the quick lock buckle 31 is fixed on the lower seat body 12, and the quick lock buckle 31 is locked on the transfer seat 41.

[0026] The upper seat 11 and the lower seat 12 are both rectangular frames. The upper seat 11 and the lower seat 12 are arranged parallel to each other up and down. The first connecting arm 111 and the second connecting arm 112 are respectively fixed on the same side of the length direction of the upper seat 11 and the lower seat 12. The first connecting arm 111 and the second connecting arm 112 are vertically arranged. The first connecting arm 111 and the second connecting arm 112 are hinged to each other. The locking arm 21 and the limiting arm 22 are respectively fixed on the other side of the length direction of the upper seat 11 and the lower seat 12.

[0027] The locking arm 21 is vertically hinged on the upper seat body 11 , and the limiting arm 22 is vertically fixed on the lower seat body 12 . The locking arm 21 is rotated to make the locking arm 21 and the limiting arm 22 interlocked.

[0028] like Figures 3 to 5 After the locking arm 21 rotates, in order to enable the locking arm 21 to automatically reset, an elastic mechanism is provided between the locking arm 21 and the upper seat body 11, and the elastic mechanism includes a turn pin 51, a spring 52 and a nut. The turn pin 51 is horizontally inserted into the upper seat body 11, one end of the turn pin 51 is hinged to the locking arm 21, and the other end is threadedly connected to the nut. The nut positions the turn pin 51 on the upper seat body 11, and the spring 52 is sleeved on the turn pin 51, rotating the locking arm 21 outward and compressing the spring.

[0029] A locking groove 211 is provided at the bottom end of the locking arm 21 , and a locking pin 221 is provided at the top end of the limiting arm 22 . The locking groove 211 and the locking pin 221 are buckled with each other.

[0030] When the upper seat 11 is closed and the locking arm 21 and the limiting arm 22 are mutually buckled, in order to make the latch pin 221 fall into the locking groove 211 more smoothly, the bottom end of the locking arm 21 is provided with an inclined surface for guidance. The inclined surface makes the locking arm 21 and the limiting arm 22 more smoothly engaged. When releasing the locking relationship, the locking arm 21 can be manually pulled outward.

[0031] The present invention also provides a lifting structure on the lower seat body 12, which is an airbag, and a horizontally arranged fixing plate 61 is provided on the airbag. The airbag is inflated and causes the fixing plate 61 to move toward the upper seat body 11. After the upper seat body 11 and the lower seat body 12 are buckled together, when it is necessary to fix the seat between the upper seat body 11 and the lower seat body 12, the airbag is inflated to fix the seat between the upper and lower seat bodies.

[0032] like Figure 6The quick lock buckle 31 of the present invention includes a lock seat 311, a lock pin 312, a spring and a wrench 313. The lock seat 311 is provided with an arc lock groove 314 and a mounting hole, the arc lock groove 314 and the mounting hole are connected, the lock pin 312 is elastically supported in the mounting hole by a spring, and the bottom end of the lock pin 312 extends into the arc lock groove 314, and the top end is placed outside the lock seat 311 and fixedly connected to the wrench 313. A lock shaft 411 is provided on the transfer seat 41, the lock shaft is placed in the arc lock groove 314, the lock pin 312 is placed below the lock shaft and limits the lock seat 311 on the lock shaft.

[0033] One end of the lower seat body 12 is connected to the lock shaft through the quick lock buckle 31, and the other end is supported on the transfer seat 41. The lower seat body 12 can rotate along the lock shaft. When removing it, pull the wrench 313 outward and rotate it 180° to make the locking pin 312 disengage from the arc lock groove 314. Under the action of the spring, the wrench 313 contacts the outer wall of the lock seat 311.

[0034] The upper seat 11 and the lower seat 12 are both rotatably connected with rollers 71, and the rollers 71 are used to guide the movement of the foaming mold frame on the annular foaming production line. The lower seat 12 is assembled on the annular foaming production line through a quick lock buckle 31. Figure 7 .

[0035] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
