[0050] The working principle of the utility model is described in detail as follows:

[0051] When the mold is demolded, the external power device drives the top plate 2 to vertically move upwards along the Z-axis direction, at this time, the straight ejection mechanism 3 and the inclined ejection mechanism 4 fixed on the top plate 2 are synchronously moved upwards along with the top plate 2, the first straight ejection rod 31 and the second straight ejection rod 32 of the straight ejection mechanism 3 directly push the bottom of the formed product, and the preliminary ejection in the Z-axis direction is realized.

[0052] When the inclined ejection rod 41 of the inclined ejection mechanism 4 moves upwards along with the top plate 2, the first rack 411 on the inclined ejection rod 41 is meshed and driven with the second rack 432 of the inclined ejection block 43, since the extension directions of the first rack 411 and the second rack 432 are parallel to the X-axis, the inclined ejection block 43 approaches the straight ejection mechanism 3 along the X-axis direction under the guidance of the inclined groove 111, this action makes the second ejection block 321 on the top of the inclined ejection block 43 contact with the side wall of the product, applies a transverse pushing force, assists the product to separate from the side lateral undercut structure of the mold cavity, and completes the demolding in the X-axis direction.

[0053] The X-axis movement of the inclined ejection block 43 is matched with the convex strips 47 of the first sliding piece 44 and the second sliding piece 45 through the '' V''-shaped grooves 46 on both sides of the inclined ejection block 43, is converted into linkage in the Y-axis direction, and specifically, when the inclined ejection block 43 moves in the X-axis direction, the '' V''-shaped grooves 46 contact with the inclined surfaces of the convex strips 47, force the first sliding piece 44 and the second sliding piece 45 to approach each other along the Y-axis direction, and the Y-axis movement of the sliding pieces is further guided through the guide groove 52 in the fixed block 5 and the sliding block 53, ensures that the action is stable, the buckle clamping hooks on the sides of the first sliding piece 44 and the second sliding piece 45 shrink and separate from the side recess structure of the product along the Y-axis direction, and the product is prevented from being stuck during demolding.

[0054] After the demolding is completed, the external power is stopped, the top plate 2 moves downwards along the Z-axis under the action of the reset mechanism, at this time: the spring 51 between the fixed block 5 and the inclined ejection block 43 releases the elastic force, pushes the inclined ejection block 43 to move reversely along the X-axis, resets to the initial position, the first sliding piece 44 and the second sliding piece 45 separate along the Y-axis direction under the guidance of the spring 51 and the '' V''-shaped grooves 46, and recover to the state before demolding, the elastic reset design replaces the traditional rigid transmission, reduces the wear caused by long-term use, and improves the reset accuracy and reliability.

[0055] When the top plate 2 moves to the highest point to complete the first ejection, the secondary ejection needle 25 of the secondary ejection assembly 23 receives resistance to move downward and serves as a fulcrum, the rotating piece 24 rotates relative to the top plate 2 around the fulcrum, and the first straight ejection rod 31 connected with the end of the rotating piece 24 is pushed upward again to complete the secondary ejection upward and realize the final demolding.

[0056] The utility model discloses an innovation lies in: mould structure is through mechanical linkage and is converted into multidirectional demolding action to single vertical ejection example, need not two external power device, has simplified power system, reduced mould complexity and manufacturing cost, adopt integrated transmission design, avoid the difficulty of multiple power source collaborative control, promote synchronous stability, replace traditional rigid transmission with elastic reset mechanism, reduce the abrasion of use, enhance reset reliability.
