Description

After the plastic product is formed in the mold, a solid ejector pin is often used to eject the plastic product from the bottom of the mold. However, when the plastic product is just formed, due to its plasticity, using an ejector pin to directly lift the plastic product can easily cause the plastic product to deform, thereby reducing the yield rate. At the same time, when the plastic product is just formed, it is possible that the plastic product adheres to the side wall of the mold. In this case, using an ejector pin to directly lift the plastic product may also cause the plastic product to deform, thereby reducing the yield rate. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Figures 1 to 11 As shown, the present invention provides a recycled plastic molding die, comprising: A fixed seat 1 is provided with a rotatable rotating seat 11 inside the fixed seat 1, a driving mechanism 12 is provided at the bottom of the rotating seat 11, the driving mechanism 12 is a reduction motor or a servo motor, which is used to drive the rotating seat 11 to rotate, and a plurality of mold base grooves 111 for carrying the mold base 2 are opened on the rotating seat 11, which is used to accommodate the mold base 2.

[0031] The circulation processing mechanism 3 includes a shell 35, which is an open bulb-shaped structure. The outer side of the fixed base 1 is provided with a first through slot 13 and a second through slot 14. The two ends of the shell 35 are respectively connected to the first through slot 13 and the second through slot 14. In the working state, the mold base 2 in the rotating base 11 leaves the fixed base 1 through the second through slot 14 under the action of the shifting mechanism 4, enters the vibration part 31, and after completing the demolding work, enters the mold base groove 111 through the first through slot 13. The shell 35 is sequentially provided with a vibration part 31 for vibrating the mold base 2, a conveyor belt 32 for transmitting the mold base 2, an ejection mechanism 33 for removing the finished plastic product in the mold base 2, and a pushing mechanism 34 for pushing the mold base 2 after the plastic product is removed into the mold base groove 111.

[0032] The moving mechanism 4 is used to move the mold base 2 in the rotating base 11 to the vibration part 31 .

[0033] Specifically, the shifting mechanism 4 includes a support plate 41, which is fixed on the inner side of the fixed base 1 and located on the side close to the vibration part 31. A rotatable shaft 43 is installed on the support plate 41. The bottom of the mold base 2 is provided with a strip pattern portion 26. The outer side of the shaft 43 has a friction portion adapted to the strip pattern portion 26. A third motor 42 is installed on one side of the support plate 41. When the third motor 42 rotates, it can drive the shaft 43 to rotate. The shaft 43 has a friction portion for cooperating with the strip pattern portion 26 at the bottom of the mold base 2. Under the action of friction, the mold base 2 is driven into the vibration part 31.

[0034] More specifically, Fig. 9 As shown, the friction part is a first friction part 44 , which is spirally wound around the outer side of the rotating shaft 43 to increase the friction force and drive the mold base 2 to enter the vibration part 31 .

[0035] Alternatively, the friction portion is a second friction portion 45 , which is striped and matches the pattern of the striped pattern portion 26 , thereby increasing the friction force and also driving the mold base 2 to enter the vibration portion 31 .

[0036] The vibration part 31 includes a plurality of rollers 312 rotatably arranged on the inner wall of the shell 35, and a plurality of rows of raised parts 313 arranged side by side are symmetrically arranged on the outer side of the rollers 312, and the raised parts 313 on any two adjacent rollers 312 are not in the same horizontal plane, forming an uneven state, so that when the mold base 2 is transported to the rollers 312, under the action of the raised parts 313, the mold base 2 enters a vibration state, so that the plastic products in the mold base 2 vibrate, and the plastic products complete the step of separating from the inner wall of the mold base 2 in the vibration state.

[0037] Specifically, in order to prevent excessive vibration force, a cover plate 311 is further provided. The cover plate 311 is provided above the rotating roller 312 . The cover plate 311 is an inverted U-shaped structure and does not affect the normal transmission of the mold base 2 .

[0038] More specifically, Figure 4 As shown, one end of the roller 312 passes through the shell 35 and is connected to a transmission wheel 315. The outer sides of several transmission wheels 315 are connected through transmission belts 316. One transmission wheel 315 located on one side is fixedly connected to the output shaft of the first motor 314. The first motor 314 is fixed to the fixed base 1 with a bracket, and is used to drive the roller 312 to rotate so as to transmit the mold base 2 onto the conveyor belt 32.

[0039] Then it enters the ejection mechanism 33. In the ejection mechanism 33 step, the mold base 2 on the conveyor belt 32 can be taken manually or by setting a manipulator. No matter which method is used, the plastic product removal work can be completed. When taking out, the ejection mechanism 33 includes a compressed air cavity 332, one side of the compressed air cavity 332 is connected with an air inlet pipe 333, and a one-way valve 3331 is installed on the outer side of the air inlet pipe 333. The top of the compressed air cavity 332 is connected with an air supply pipe 336 for conveying compressed air, and an electromagnetic valve is installed on the outer side of the air supply pipe 336. An air pump 331 is installed on one side of the shell 35, and the air outlet of the air pump 331 is flange-connected with the air inlet pipe 333. The air pump 331 is used to convey external air into the compressed air cavity 332. At this time, the electromagnetic valve on the air supply pipe 336 is closed. The gas is compressed in the compressed air cavity 332, and in order to facilitate the staff or the robot to take out the plastic product, a plurality of second elastic members 335 are bonded to the upper surface of the compressed air cavity 332, and the tops of the plurality of second elastic members 335 are fixedly connected with a supporting plate 334. When taking out, the mold base 2 is placed on the supporting plate 334. Under the action of the gravity of the mold base 2, the supporting plate 334 squeezes the second elastic members 335 downward. At the same time, an air inlet 25 matching the position of the air pipe 336 is opened at the bottom of the mold base 2. At the same time, the solenoid valve is opened, and the compressed air inside the compressed air cavity 332 enters the mold cavity 21 of the mold base 2 through the air pipe 336 and the air inlet 25. The gas pushes the top plate 23 upward, and the top plate 23 lifts the molded plastic product, that is, the plastic product moves upward, and the mold base 2 moves downward, so that the plastic product is exposed, which is convenient for taking out the plastic product.

[0040] As a preferred embodiment of the above technical solution, five air pipes 336 are provided, wherein one air pipe 336 is located in the middle of the upper surface of the compressed air cavity 332, and the other four air pipes 336 are arranged in a ring shape on the outside of the middle air pipe 336. A through hole 3341 matching the position of the air pipe 336 is provided on the supporting plate 334. A mold cavity 21 is provided on the inner side of the mold base 2. A top plate 23 is provided inside the mold cavity 21. A first elastic member 22 is fixedly connected to the bottom of the top plate 23. The first elastic member 22 is fixed in the mold cavity 21. The top plate 23 and the mold cavity 21 have an interference fit. With this arrangement, when the compressed air pushes the top plate 23 upward, the top plate 23 can be lifted up from multiple directions. The top plate 23 moves upward more smoothly. The top plate 23 and the mold cavity 21 have an interference fit and are connected with the first elastic member 22 for elastic reset.

[0041] At the same time, a pushing mechanism 34 is provided, including a limit plate 341. There are two limit plates 341. The two limit plates 341 are respectively fixed to both sides of the upper surface of the shell 35. A vertical plate 342 is fixed on the limit plate 341. A rotatable rotating rod 344 is installed on the vertical plate 342. Two push plates 345 are symmetrically fixedly connected to the outer side of the rotating rod 344. When the mold base 2 is placed on the pushing mechanism 34, the rotating rod 344 rotates, and the mold base 2 can be transported into the mold base groove 111 through the push plate 345. After taking out the plastic product, the worker The worker or manipulator places the mold base after taking out the plastic product on the pushing mechanism 34. A second motor 343 is installed on one side of the vertical plate 342. After the second motor 343 is started, it drives the rotating rod 344 to rotate, and the rotating rod 344 drives the pushing plate 345 to rotate. The pushing plate 345 transports the mold base 2 into the mold base groove 111. At the same time, two clamping blocks 24 are symmetrically formed on the outer side of the mold base 2. Two clamping grooves 112 that are compatible with the clamping blocks 24 are provided on both sides of the mold base groove 111, so as to ensure the connection stability between the mold base 2 and the mold base groove 111. Fig.11 As shown, X1 is the motion trajectory of the mold base 2, and X2 is the rotation trajectory of the push plate 345.

[0042] When plastic products are continuously molded: The raw material of the plastic product is poured into the mold cavity 21 in the mold base 2. At the same time, the driving mechanism 12 works to drive the rotating base 11 to rotate on the fixed base 1. The mold base groove 111 on the rotating base 11 is customized according to the processing requirements. At the same time, a heat dissipation mechanism is provided inside the rotating base 11 to dissipate the heat in the mold base 2, so that the plastic product in the mold base 2 can be quickly formed. In the continuous forming of the plastic product, the mold base 2 near the second through groove 14 will enter the vibration part 31 under the action of the shifting mechanism 4. The plastic product entering the vibration part 31 is constantly vibrated, so that the plastic product is separated from the mold base 2, and then on the conveyor belt 32 Under the action of the ejection mechanism 33, the plastic product is separated from the mold base by a staff member or a manipulator. Then the mold base 2 is placed in the pushing mechanism 34 and pushed into the mold base groove 111 by the pushing mechanism 34. Continuous molding has high processing efficiency. There is no need to constantly replace new molds. It is only necessary to set a fixed mold according to the molding time of the plastic product. At the same time, if the molding time of the plastic product is slow, a condensation section can be set before the vibration section 31, that is, under the action of the shifting mechanism 4, the mold base 2 carrying the plastic product first enters the condensation section, and under the action of the condensation section, the plastic product is cooled to accelerate its cooling process, and then enters the vibration section 31 after cooling.

[0043] Specifically, the condensation part can be composed of a sealed condensation chamber with double-sided channels. When the mold base 2 carrying the plastic product enters the condensation chamber, one side channel is opened. When the mold base 2 carrying the plastic product leaves the condensation chamber, the other side channel is opened to ensure the temperature in the condensation chamber. At the same time, a conveyor belt 32 is also arranged in the condensation chamber to convey the mold base 2 carrying the plastic product. The molding of the plastic product is completed during the conveying process, thereby achieving continuous operation and liberating labor.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
