The drip molding products can be divided into single-sided drip molding and double-sided drip molding products.

In this embodiment, the clamping and lifting drive mechanism 524 is a cylinder.A transverse transmission block is provided at the output end of the clamping transverse driving mechanism 526, and the transverse transmission block is connected to the clamping connecting body 5221. The clamping transverse driving mechanism 526 is connected to the upper synchronous plate 57. A guide shaft 58 is connected in series between the upper synchronous plate 57, the jacking mechanism mounting plate 56, and the lower synchronous plate 55. The guide shaft 58 serves as a moving guide. By designing the guide shaft 58, the upper synchronous plate 57 and the lower synchronous plate 55 can be moved along the direction of the guide shaft 58.

[0027] The mold fixing plate 510 is provided with a sliding guide groove 59 through which the guide rods can pass. The sliding guide groove 59 serves as a moving guide so that each guide rod can move more smoothly along a specified direction. Figure 10-11 The flipping drive device 53 includes a rotating shaft mounting seat 541, a rotating shaft 542, a rotating block 543, a motor 544, and a transmission gear set 545. The rotating shaft 542 is connected between the two rotating shaft mounting seats 541. One end of the rotating block 543 is connected to the rotating shaft 542, and the other end is connected to the mold fixing plate 510. The rotating block 543 serves as a swing arm component to assist the flipping of the upper mold device 51. The output end of the motor 544 is connected to the rotating shaft 542 through the transmission gear set 545. When the motor 544 is started, it drives the transmission gear set 545 and the rotating shaft 542 to rotate, so that the upper mold device 51 flips along the rotating shaft 542 toward the lower mold device 52 and closes the mold with the upper mold device 51. Fig.11 The upper mold device 51 is also provided with a mold release driving mechanism 527, a mounting plate 528 for the mold release driving mechanism 527, and the mounting plate 528 is connected to the guide shaft 58. The mold release driving mechanism 527 is used to drive the upper mold and the lower mold of the upper mold device 51 to close the mold.

[0028] The working principle of the mold closing and flipping mechanism is as follows: when the mold positioning mechanism 521 positions the mold, the mold positioning mechanism 521 is driven by the positioning transverse movement driving mechanism 525 to make the mold positioning mechanism 521 reciprocate left and right. When it moves to the top of the mold positioning groove 531, the mold positioning mechanism 521 is driven by the positioning lifting driving mechanism 523 to reciprocate up and down, and the mold positioning groove 531 is pressed down and clamped for positioning by the positioning block 5216. When the mold clamping mechanism 522 clamps the mold sideways, the mold clamping mechanism 522 is moved upward as a whole under the transmission of the clamping and lifting driving mechanism 524, so that the clamping roller 5225 on the clamping guide rod 5222 is exposed on the mold fixing plate 510, and then reciprocated left and right under the transmission of the clamping and lateral movement driving mechanism 526, so that the clamping roller 5225 clamps the mold sideways, so that the mold is fixed on the mold fixing plate 510 under the joint action of the mold positioning mechanism 521 and the mold clamping mechanism 522, to prevent errors such as positional offset of the mold. When the mold side is clamped and adjusted, the positioning guide rod 5212 on the mold positioning mechanism 521 moves downward to the bottom of the mold fixing plate 510, so that the positioning guide rod 5212 avoids the mold to prevent collision with the mold. After the above actions are completed, the flip driving device 53 is started, driving the transmission gear set 545 and the rotating shaft 542 to rotate, so that the upper mold device 51 flips along the rotating shaft 542 toward the lower mold device 52, and forms a mold-closing state with the upper mold device 51. By using the mold closing flip mechanism, the stability and accuracy of the mold closing process of the upper mold and the lower mold are improved, and the mold closing flip mechanism can be applied according to molds of different sizes, with high flexibility and automatic flipping.

When the upper and lower molds need to be opened, the positioning block 6216 on the positioning guide rod 6212 presses down and clamps the lower mold. At the same time, the unfolding and lifting guide rod 6271 moves upward under the drive of the unfolding and lifting drive mechanism 6273, so that the unfolding and lifting guide rod 6271 rises from the inside of the positioning guide rod 6212, and the upper mold is opened under the joint push of the unfolding and lifting guide rod 6271 and the unfolding push block 6274.

The clamping and lateral movement drive mechanism 626 is connected to the upper synchronous plate 67. A guide shaft 68 is connected in series between the upper synchronous plate 67, the lifting mechanism mounting plate 66, and the lower synchronous plate 65. The guide shaft 68 serves as a moving guide. By designing the guide shaft 68, the upper synchronous plate 67 and the lower synchronous plate 65 can move along the direction of the guide shaft 68. When the mold clamping mechanism 622 clamps the mold 63 on the sides, the mold clamping mechanism 622 is moved upward as a whole under the transmission of the clamping jacking drive mechanism 624, so that the clamping roller 6225 on the clamping guide rod 6222 is exposed on the mold fixing plate 610, and then reciprocates left and right under the transmission of the clamping transverse driving mechanism 626, so that the clamping roller 6225 clamps the mold 63 on the sides, so that the mold 63 is fixed on the mold fixing plate 610 under the joint action of the mold positioning mechanism 621 and the mold clamping mechanism 622, so as to prevent the mold 63 from having errors such as positional offset. The mold fixing plate 610 is provided with a sliding guide groove 69 for the guide rod to pass through, and the sliding guide groove 69 plays a role of moving guide, so that each guide rod can move more smoothly along the specified direction.

[0034] The working principle of the mold opening and flipping mechanism is as follows: when it is necessary to open the upper and lower molds, the positioning block 6216 on the positioning guide rod 6212 of the lower mold device 62 presses down and clamps the lower mold, and the unfolding and lifting guide rod 6271 moves upward under the drive of the unfolding and lifting drive mechanism 6273, so that the unfolding and lifting guide rod 6271 rises from the inside of the positioning guide rod 6212, and the upper mold is pushed away from the lower mold by the thrust of the unfolding and lifting guide rod 6271; at the same time, the positioning guide rod 6212 on the upper mold device 61 extends out, and the positioning block 6216 on the positioning guide rod 6212 is clamped into the positioning groove 631 of the upper mold and performs a clamping action. After the above actions are completed, the upper mold device 61 is flipped under the drive of the flipping drive device 64, and the mold clamping mechanism 622 and the mold positioning mechanism 621 on the upper mold device 61 perform clamping and clamping actions under the joint action of the mold clamping mechanism 622 and the mold positioning mechanism 621, so that the upper mold is completely separated from the lower mold. The positioning groove 31 of the mold 63 can accommodate the positioning block 216 and the expansion push block 274 to be clamped therein at the same time, that is, when the positioning block 216 on the lower mold device 62 is connected to the positioning groove 31, the positioning block 216 and the expansion push block 274 are staggered and clamped in the positioning groove 31 of the mold 63. The mold opening flip mechanism is used, and the upper mold and the lower mold are separated in advance by a certain distance through the auxiliary expansion mechanism, and then the upper mold device takes over the grabbing mold to completely separate the upper mold and the lower mold, saving mold opening time. The upper mold and the lower mold are separated in advance by a certain distance with the help of the auxiliary expansion mechanism, so as to facilitate the upper mold device to quickly open the upper mold, which greatly improves the production efficiency.
