[0041] When the second gear 33 rotates, it can drive the winding wheel 36 to rotate simultaneously, and then the connecting rope 34 can be wound up to drive the receiving cavity 31 to move in a direction away from the supporting base frame 37 .

[0042] The positioning plate 9 is fixedly mounted on the top front end of the displacement bracket 24, the displacement bracket 24 is slidably sleeved on the first mold 3, the first mold 3 is fixedly mounted on the top of the bottom plate 29 away from the vertical frame 28, the first photoelectric sensor 12 is electrically connected to the first nozzle 11, the first gear 13 is meshed with the first rack 15, the first nozzle 11 is vertically aligned with the second mold 16, the button switch 25 is electrically connected to the dual-axis motor 14, the second nozzle 23 is inclined at 30° and is arranged inside the movable ejector 22, a circular hole is opened at the rear end center of the rear plate 20, the inner center of the rear plate 20 is horizontally aligned with the limit rod 32, and the movable ejector 22 is away from the rear plate 2 0 is fixedly mounted with a round gasket at one end, and a round groove is provided inside the side end of the second mold 16 away from the second spring 21, movable grooves are provided on both sides of the supporting base 37, and the displacement rod 40 is located inside the movable groove, a release hole is provided at the bottom end of the receiving cavity 31, the first nozzle 11 and the second mold 16 are spaced 3 cm apart, the first guide tube 7 is communicated with the inside of the first nozzle 11, the second nozzle 23 is communicated with the second guide tube 17, the second mold 16 and the displacement bracket 24 are both provided with jacks similar to the movable ejector rod 22, transverse slide grooves are provided inside the two sides of the displacement bracket 24, and the second guide tube 17 is located inside the transverse slide grooves.

[0043] The working principle of Example 1 is as follows: when in use, the end of the displacement bracket 24 facing away from the second mold 16 is first connected to an external hydraulic device, so that when the hydraulic device is started, it can drive the displacement bracket 24 to contact or separate from the first mold 3. Subsequently, the hydraulic device can be started to drive the displacement bracket 24 to move until the second mold 16 contacts the inside of the first mold 3, so that the first mold 3 and the second mold 16 can perform injection molding, so that the molded material can remain on the second mold 16, and then the external hydraulic device is turned on to drive the displacement bracket 24 to move toward the end away from the first mold 3. When the displacement bracket 24 moves to the extreme position at the rear end, the end of the movable ejector rod 22 close to the rear plate 20 can contact the support rod on the limit rod 32, and through the support rod The movable ejector 22 is limited by the rod, and the movable ejector 22 moves toward the end away from the second mold 16, so that the movable ejector 22 can extrude the material on the second mold 16 outward, and when the movable ejector 22 moves to the extreme position toward the end away from the second mold 16, the second guide tube 17 can drive 19 to contact the second photoelectric sensor 26, so that the second photoelectric sensor 26 can be triggered to start 19, and the air pipe 19 is connected with the outside, so that when 19 is started, the gas can be transported to the inside of the second guide tube 17, and the second guide tube 17 is connected with the second nozzle 23, so that the second nozzle 23 can spray gas, and the second nozzle 23 is arranged inside the movable ejector 22 at a 30° angle, so that the gas sprayed from the second nozzle 23 can drive the movable ejector 22 to move to the inside of the movable ejector 22. The material on the rod 22 moves toward the end away from the second mold 16, which can prevent the material from being retained on the movable ejector 22 for a long time. At the same time, when 19 contacts the second photoelectric sensor 26, it can also drive the contact plate 18 to contact the button switch 25, so that the button switch 25 can be triggered to start the dual-axis motor 14, drive the first gear 13 to rotate, and when the first gear 13 rotates, it can drive the first rack 15 to move downward, so that the first nozzle 11 can move downward. When the first nozzle 11 moves downward, it can pass through the first photoelectric sensor 12, thereby triggering the start of the first nozzle 11, and communicating with the external release agent storage cavity through the first guide pipe 7, so that when the first nozzle 11 is started, the release agent can be sprayed outward, and the first nozzle 11 moves downward. During the movement, the material can be quickly moved out of the movable ejector rod 22, so that when the first nozzle 11 moves downward, it can prevent contact with the material. Subsequently, when the first nozzle 11 moves downward, the surface of the movable ejector rod 22 and the second mold 16 can be sprayed with a release agent. Each time the dual-axis motor 14 is started, it will only drive the first gear 13 to rotate one circle, so that after the first gear 13 rotates one circle, the first rack 15 can drive the first nozzle 11 to move downward to the bottom of the second mold 16, so that the second mold 16 and the movable ejector rod 22 can be completely sprayed with a release agent. Subsequently, the external hydraulic equipment is started to drive the displacement bracket 24 to move toward the end close to the first mold 3, so that the movable ejector rod 22 can be out of contact with the support rod inside the limit rod 32.The elasticity of the second spring 21 will drive the movable push rod 22 to reset, so that the movable push rod 22 can move to the inside of the second mold 16 again, and can be connected to the second mold 16 as a whole, so that the second mold 16 and the first mold 3 are molded again. When the movable push rod 22 is reset, it can drive 19 to disengage from the second photoelectric sensor 26, and the contact plate 18 to disengage from the button switch 25, so that the dual-axis motors 14 and 19 can be powered off. At this time, when the dual-axis motor 14 is powered off, the first rack 15 will lose its meshing force, and the elasticity of the first spring 6 will drive the limit bracket 8 and the first rack 15 to move upward and reset, so that the first nozzle 11 can move to its original position. At the same time, when the first nozzle 11 moves to above the sensing area of ​​the first photoelectric sensor 12, the first photoelectric sensor 12 can lose its sensing, and the first nozzle 11 no longer sprays the release agent. Subsequently, when the displacement bracket 24 continues to move toward the end close to the first mold 3, it can drive the second rack 27 to pass through the second The gear 33 can drive the reel 36 to rotate, so that the reel 36 can pull the receiving cavity 31 to move to the end away from the supporting frame 37 through the connecting rope 34, and the molded material that has fallen before can fall into the inside of the receiving cavity 31, so that when the second rack 27 completely passes through the second gear 33, it can drive the reel 36 to rotate several circles, so that the connecting rope 34 can pull the receiving cavity 31 to move outward to the limit position. At this time, the bottom end of the receiving cavity 31 will be misaligned with the supporting frame 37, so that the molded material can fall downward and be discharged. The displacement rod 40 moves in the movable grooves on both sides of the supporting frame 37, so that the receiving cavity 31 can be ensured to move in a straight line. Subsequently, when the second rack 27 passes through the second gear 33, the second gear 33 will lose its meshing force, and the elasticity of the third spring 39 will drive the displacement rod 40 to pull the receiving cavity 31 to reset, so that the receiving cavity 31 can receive the material again, completing the work of discharging the material outward.

[0044] Example 2

[0045] On the basis of Example 1, Fig.10 As shown, the support base 37 also includes a collecting cavity 41 and a sliding key 42 . The sliding key 42 is symmetrically slidably inserted into the bottom end of the support base 37 , and the collecting cavity 41 is fixedly installed at the bottom end of the sliding key 42 .

[0046] When implementing this embodiment, when the formed material falls from the bottom end of the inner part of the support base 37, the collecting cavity 41 is vertically aligned with the support base 37 so that the fallen material can be received. When a certain amount of material accumulates in the collecting cavity 41, the collecting cavity 41 can be pulled to the end away from the support base 37 to facilitate the transfer of the material. Subsequently, when the material in the collecting cavity 41 is completely emptied, the sliding key 42 can be slid into the interior of the slot through the symmetrical slots provided at the bottom end of the support base 37, so that the collecting cavity 41 can move in a straight line at the bottom end of the support base 37, thereby ensuring the docking accuracy between the collecting cavity 41 and the support base 37, and preventing the collecting cavity 41 from falling, thereby completing the work.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
