The connecting frame 3 is provided with the same number of winding mechanisms 9 as the limiting columns 8. The number of limiting columns 8 and winding mechanisms 9 is four groups, which are distributed in a rectangular shape. A connecting piece 10 is installed between the output end of each winding mechanism 9 and the limiting column 8 at the corresponding position of the upper mold 5.

[0042] The connection frame 3 is provided with an embedding groove at the lower side of each winding mechanism 9, and each connecting member 10 penetrates the corresponding embedding groove and is connected to the limiting column 8. After the upper mold 5 and the connection frame 3 are assembled, each limiting column 8 on the upper side thereof is respectively embedded in the corresponding embedding groove, and is connected with the embedding groove to maintain a stable state, thereby preventing the connection frame 3 from shaking when the mold is closed or opened.

[0046] After the upper mold 5 and the connecting frame 3 are assembled, each calibration block 6 contacts the corresponding calibration component 17 respectively, and each calibration component 17 generates inspection data based on pressure. By monitoring the inspection data, the assembly status of the upper mold 5 and the connecting frame 3 is monitored.

[0047] The calibration component 17 includes a sensing module 171 connected to the connecting frame 3. A connecting plate 172 connected to the connecting frame 3 is arranged on the lower side of the sensing module 171. A plurality of contact blocks 173 are slidably connected inside the connecting plate 172. A first elastic member 174 is installed between each contact block 173 and the connecting plate 172.

[0048] Reference Figure 4 As shown, the heat dissipation assembly module 12 includes an assembly groove 121, which is a T-shaped structure, including a narrow connection section and a wide connection section, the wide connection section is connected to the outside, and after the heat dissipation connection tube 11 is assembled with the heat dissipation assembly module 12, one end of the heat dissipation connection tube 11 abuts against the intersection of the wide connection section and the narrow connection section, and the inner wall of the heat dissipation connection tube 11 is flush with the inner wall of the narrow connection section;

[0049] An assembly rack 122 is installed inside the narrow connection section, and one end of the assembly rack 122 extends to the inside of the wide connection section. After the heat dissipation connection tube 11 is assembled with the assembly groove 121, the assembly rack 122 extends to the inside of the heat dissipation connection tube 11;

[0050] The output end of the air pump on the connecting frame 3 is connected to each expansion member 123 inside it, and the output end of the air pump on the base 1 is connected to each expansion member 123 inside it;

[0051] An expansion member 123 is installed on the outer side of the assembly frame 122. The expansion member 123 expands after gas is blown into the interior thereof, thereby sealing the connection portion between the heat dissipation connecting pipe 11 and the narrow connecting section.

[0052] Reference Figure 6-Figure 7 As shown, a resisting and extending assembly 42 is installed on the lower side of the lower mold 4, and a plurality of step grooves 41 are provided on both sides of the lower mold 4, and a stepped portion is provided inside each step groove 41, and the resisting and extending assembly 42 includes an assembly plate 421, and a plurality of second elastic members 425 are installed between the upper surface of the assembly plate 421 and the lower mold 4, and a plurality of lifting rods 422 are installed on the upper side of the assembly plate 421, and when each lifting rod 422 is not working, its top extends into the cavity of the lower mold 4, and the top of each lifting rod 422 is flush with the inner wall of the cavity of the lower mold 4;

[0053] The assembly plate 421 and each lifting rod 422 are provided with a connecting groove 423, and the top of each lifting rod 422 is provided with an air outlet 424;

[0054] After assembly, the assembly plate 421 is located on the upper side of the lifting frame 14. After the lifting frame 14 is started, the lifting rods 422 are lifted up by lifting the assembly plate 421, and the product formed inside the cavity of the lower mold 4 is separated from the lower mold 4. After the air outlet 424 rises to the inside of the cavity of the lower mold 4, air is ejected from the air outlet 424 to fill the gap between the product and the cavity of the lower mold 4, thereby preventing the product from adhering to the inside of the cavity of the lower mold 4.

[0055] Reference Figure 8-Figure 9 As shown, the locking assembly 16 includes a driving motor 161 connected to the cylinder 15, the output end of the driving motor 161 faces the lifting frame 13, and is installed with a clamping block 162, a protruding portion is provided on one side of the clamping block 162, and a bending portion is provided between the protruding portion and the body of the clamping block 162;

[0056] The distribution positions of the step grooves 41 correspond to the distribution positions of the locking components 16;

[0057] When each locking assembly 16 moves based on the cylinder 15, the internal clamping block 162 is embedded in the corresponding step groove 41, and the clamping block 162 rotates with the start of the driving motor 161, thereby clamping the bending part of the clamping block 162 with the stepped part of the step groove 41, thereby fixing the lower mold 4 inside the base 1.

[0058] Working principle:

[0059] Move the upper mold 5 to the lower side of the connecting frame 3 in a vertical direction to avoid damage to the mold core on the lower side of the upper mold 5, and then connect each limit column 8 to the connecting piece 10 of the winding mechanism 9 at the corresponding position;

[0060] Then, the winding mechanism 9 is synchronously started to lift the upper mold 5 off the ground, and then the winding mechanism 9 connected to the lower limit column 8 is started. After the upper mold 5 is turned to a horizontal state, each winding mechanism 9 is synchronously started again to lift the upper mold 5 and assemble it with the connecting frame 3;

[0061] When the upper mold 5 is assembled with the connecting frame 3, each of the limiting columns 8 on the upper side thereof is respectively embedded in the embedding groove on the lower side of the corresponding winding mechanism 9, and each of the heat dissipation connecting tubes 11 is in contact with the alignment assembly 17, and at the same time, the heat dissipation connecting tubes 11 are in contact with the heat dissipation assembly module 12;

[0062] After the calibration block 6 contacts the calibration assembly 17, it drives each contact block 173 in the calibration assembly 17 to rise, and its top contacts the sensing module 171. The sensing module 171 is provided with the same number of working ends as the contact block 173, and the working ends of each sensing module 171 generate inspection data after being pressed.

[0063] When the difference between the multiple verification data in a single calibration component 17 exceeds the preset threshold data, there is a problem in the connection between the winding mechanism 9 and the upper mold 5 at the corresponding position;

[0064] After each heat dissipation connecting tube 11 is connected to the heat dissipation assembly module 12, each air pump is started to inflate and deform each expansion member 123 so that the connection portion between each heat dissipation connecting tube 11 and the heat dissipation assembly module 12 is sealed;

[0065] Next, the lower mold 4 is transported to the upper side of the lifting frame 13, and then the lifting frame 13 is lowered, and the lower mold 4 is lowered to the inside of the base 1. Then, each cylinder 15 is started, and the clamping block 162 in each locking assembly 16 is moved to the corresponding step groove 41. Finally, the driving motor 161 in each locking assembly 16 is started, driving the clamping block 162 to rotate, and fixing the lower mold 4 in the base 1.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of this template.
