[0024] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the "one embodiment" or "embodiment" referred to here means that the specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" does not mean the same embodiment in different places in this specification, nor is it an embodiment that is independent of or mutually exclusive with other embodiments.

[0026] EMBODIMENT

[0027] Refer to Figures 1-6 For the embodiment of the utility model, the embodiment provides a mold for composite material medical bed board, which can not only realize the effect of multi-angle adjustment of the mold main body 100, but also enable the mold main body 100 to have the ability of multi-angle stay, thereby facilitating the demolding operation of the staff at the appropriate angle.

[0028] The forming mechanism 100 comprises a mold body 101 and a plurality of demolding grooves 102 arranged on the top of the mold body 101.

[0029] It should be noted that the mold body 100 can be quickly replaced according to the needs of different products to adapt to the production mode of multiple varieties. The mold body 100 is a prior art, and the working principle thereof is clear to those skilled in the art.

[0030] The demolding mechanism 200 comprises a receiving box 201 arranged below the mold body 100, a rotating shaft 202 arranged outside the receiving box 201, a driving rod 203 fixedly sleeved on the penetrating end of the rotating shaft 202, a driven rod 204 hingedly connected to the other end of the driving rod 203, a driving column 205 fixedly connected to the inner surface of the driven rod 204, a support block 206 rotatably sleeved on the outer surface of the driving column 205 and matched with the mold body 100, a support column 207 fixedly connected to the inner surface of the side of the support block 206 away from the driving column 205, and a limiting assembly 208 capable of overturning the support block 206.

[0031] Specifically, the mold body 100 is fixedly installed on the top of the support block 206, the outer end surface of the rotating shaft 202 penetrates to the outside of the receiving box 201, and a bearing sleeve matched with rotation is installed at the connection between the rotating shaft 202 and the receiving box 201.

[0032] Further, the limiting assembly 208 comprises a limiting plate 208a fixedly connected to the inner wall of the receiving box 201, a straight groove 208b arranged on the outer surface of the limiting plate 208a and matched with the support column 207, and an arc groove 208c arranged on the side of the limiting plate 208a away from the 280b and matched with the driving column 205.

[0033] Preferably, the outer surfaces of the driving column 205 and the support column 207 are in sliding contact with the inner wall of the straight groove 208b, a bearing sleeve matched with rotation is installed at the connection between the rotating shaft 202 and the limiting plate 208a, and the straight groove 208b is in communication with the inner cavity of the arc groove 208c.

[0034] It should be noted that the rotation of the rotating shaft 202 can drive the driving rod 203 to rotate synchronously, and the limiting of the driving column 205 and the supporting column 207 by the straight groove 208b can limit the driven rod 204 and the supporting block 206, so that the driving rod 203 drives the driving column 205, the supporting block 206 and the supporting column 207 to move vertically through cooperation with the driven rod 204. When the supporting column 207 moves to the position where the inner wall top of the straight groove 208b is contacted, the driving column 205 moves synchronously to the entrance of the arc groove 208c, and the driving column 205 is driven by the driven rod 204 to make the supporting column 207 as the center to move in the arc groove 208c, so that the driving column 205 drives the supporting block 206 and the mold body 100 to overturn with the supporting column 207 as the center.

[0035] It should be noted that the demolding mechanism 200 further comprises a positioning assembly 209 capable of stopping the rotating shaft 202 at multiple angles, and a rotating rod 210 fixedly sleeved on the outer surface of the rotating shaft 202.

[0036] Among them, the positioning assembly 209 can make the rotating shaft 202 stop at multiple angles, so as to facilitate the staff to carry out demolding operation at a suitable angle, and the rotating rod 210 can facilitate the user to rotate the rotating shaft 202.

[0037] Further, the positioning assembly 209 comprises a fixed block 209a fixedly connected to the outer surface of the storage box 201, a spring 209b fixedly connected to the bottom of the fixed block 209a, a pawl 209c fixedly connected to the other end of the spring 209b, a ratchet wheel 209d engaged with the outer surface of the pawl 209c and matched with the rotating shaft 202, and a rotating column 209e fixedly connected to the outer surface of the storage box 201 and matched with the pawl 209c.

[0038] Specifically, the inner surface of the pawl 209c is in rotating contact with the outer surface of the rotating column 209e, and the inner surface of the ratchet wheel 209d is fixedly connected with the outer surface of the rotating shaft 202.

[0039] In use, when the shaped bed plate needs to be taken out, the rotating rod 210 is rotated to drive the rotating shaft to rotate, the rotating shaft 202 drives the driving rod 203 and the ratchet wheel 209d to rotate synchronously, the rotating shaft 202 drives the driving rod 203 to rotate synchronously, and the ratchet wheel 209d extrudes the pawl 209c and the spring 209b. The straight groove 208b limits the driving column 205 and the supporting column 207, so that the driving column 205 and the supporting column 207 limit the driven rod 204 and the supporting block 206, so that the driving rod 203 drives the driving column 205, the supporting block 206 and the supporting column 207 to move vertically upward through cooperation with the driven rod 204. When the supporting column 207 moves to the position where the inner wall top of the straight groove 208b is contacted, the driving column 205 moves to the entrance of the arc groove 208c synchronously, the driven rod 204 continues to rotate to drive the driving column 205 to move to the inside of the arc groove 208c with the supporting column 207 as the center, and the driving column 205 drives the supporting block 206 and the mold body 100 to rotate around the supporting column 207.

[0040] After the mold body 100 is rotated to the appropriate demolding angle: the rotating rod 210 is loosened, the pawl 209c is reset by the reaction force of the spring 209b, the pawl 209c is extruded to the position where it is engaged with the ratchet wheel 209d, the pawl 209c limits the ratchet wheel 209d and the rotating shaft 202 through the limiting of the rotating column 209e, the rotating shaft 202, the driving rod 204 and the driving column 205 are prevented from rotating in the opposite direction due to gravity, so that the mold body 100 has the ability to stay at multiple angles, thereby facilitating the demolding work of the staff at the appropriate angle.

[0041] In summary, through the cooperation between the components in the demolding mechanism 200, the mold body 100 can be adjusted at multiple angles, and the mold body 100 has the ability to stay at multiple angles, thereby facilitating the demolding work of the staff at the appropriate angle, so as to reduce the risk of demolding difficulty or product damage caused by improper angle, and significantly reduce the waste rate.
