DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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.

[0042] like Figures 1 to 5 As shown, a plastic forming mold frame includes a mold frame upper plate 10, a connecting plate 11 and a mold frame lower plate 12. The mold frame upper plate 10, the connecting plate 11 and the mold frame lower plate 12 are connected from top to bottom in sequence through guide columns 13. The mold frame lower plate 12 is fixedly connected to the guide columns 13. The mold frame upper plate 10 and the connecting plate 11 are both slidably connected to the guide columns 13. The mold frame upper plate 10 and the connecting plate 11 can both slide along the guide columns 13; springs 14 are provided between the mold frame upper plate 10 and the connecting plate 11 and between the connecting plate 11 and the mold frame lower plate 12; the provision of the spring 14 can play a resetting role on the one hand, and can play a role in ensuring uniform force on the other hand.

[0043] A shaping sleeve 15 is fixed on the connecting plate 11, an upper shaping mandrel 16 is fixed on the upper plate 10 of the mold frame, and the upper shaping mandrel 16 extends into the shaping sleeve 15 through the upper part of the shaping sleeve 15; a lower shaping mandrel 17 is fixed on the lower plate 12 of the mold frame, and the lower shaping mandrel 17 extends into the shaping sleeve 15 through the lower part of the shaping sleeve 15; the shaping operation is achieved through the cooperation of the upper shaping mandrel 16, the lower shaping mandrel 17 and the shaping sleeve 15.

[0044] A radial through hole 150 is provided in the middle of the shaping sleeve, through which the product can enter the shaping sleeve or be removed from the shaping sleeve.

[0045] Specifically: in order to ensure the shaping accuracy, the above components need to ensure the processing accuracy. When using this shaping mold frame, first place the whole body under the press, then put the product to be shaped into the shaping sleeve 15, and finally start the press, and press down to achieve shaping.

[0046] During the pressing process, the press applies force to the upper plate 10 of the mold frame, causing the spring 14 to generate elasticity, and under the action of the spring 14, the upper plate 10 of the mold frame and the connecting plate 11 are ensured to be linked; at this time, the upper shaping core rod 16 on the upper plate 10 of the mold frame and the lower shaping core rod 17 on the lower plate 12 of the mold frame will squeeze the product, and the pressure will be maintained for a period of time to achieve shaping; after the shaping is completed, the press moves upward, and under the action of the spring 14, the upper plate 10 of the mold frame and the lower plate 12 of the mold frame are reset, and the upper shaping core rod 16 and the lower shaping core rod 17 are also reset and do not contact the product, and then the product can be taken out through the radial through hole 150.

[0047] The shaping sleeve 15, the upper shaping core rod 16 and the lower shaping core rod 17 can be designed according to different needs, that is, the shaping sleeve 15, the upper shaping core rod 16 and the lower shaping core rod 17 can be designed to correspond to the shape of the product; different shaping sleeves 15, the upper shaping core rod 16 and the lower shaping core rod 17 can be replaced to produce different products; take the production of 1083 piston as an example: the above-mentioned parts are replaced before shaping, and during the shaping process, the upper and lower shaping core rods will contact the two planes of the 1083 piston at the same time for shaping.

[0048] Furthermore, the number of guide posts 13 can be set as needed, preferably four, and the spring 14 is sleeved on the guide post 13. The number of springs 14 can be set as needed; a spring 14 between the mold frame upper plate 10 and the connecting plate 11 and a spring 14 between the connecting plate 11 and the mold frame lower plate 12 are called a pair of springs. As in the present solution, two pairs are provided, that is, a pair is provided on each of the two diagonal guide posts 13. The two ends of the spring 14 between the mold frame upper plate 10 and the connecting plate 11 are respectively against the mold frame upper plate 10 and the connecting plate 11, and the two ends of the spring 14 between the mold frame lower plate 12 and the connecting plate 11 are respectively against the mold frame lower plate 12 and the connecting plate 11. Of course, in addition to being sleeved on the guide post 13, the spring 14 can also be set at other positions as needed.

[0049] Furthermore, a positioning clamp 18 is provided on the guide column 13, and the positioning clamp 18 is located between the mold frame upper plate 10 and the connecting plate 11. The positioning clamp 18 limits the movement of the mold frame upper plate 10 to prevent the mold frame upper plate 10 from moving downward excessively under the action of the press; and it can also limit the upward movement of the connecting plate 11.

[0050] Further, the upper shaping mandrel 16 is connected to the upper plate 10 of the mold frame by the upper fixing bolt 100; the lower shaping mandrel 17 is connected to the lower plate 12 of the mold frame by the lower fixing bolt 110. That is, the fixed connection is achieved by bolts, and of course, other fixed connection methods such as clamping can be set as needed.

[0051] like Figures 6 to 9 As shown, a finishing machine includes a loading and unloading mechanism 2 and the above-mentioned shaping mold frame 1; the loading and unloading mechanism 1 includes a frame 20 and a conveying mechanism 21, a loading mechanism 22 and a unloading mechanism 23 arranged on the frame 20, and the conveying mechanism 21 is used to convey the product into the shaping sleeve or remove the product from the shaping sleeve; the loading mechanism 22 is used to transfer the product to the conveying mechanism 21, and the unloading mechanism 23 is used to take the product on the conveying mechanism 21 out.

[0052] When in use, the product to be shaped is placed on the conveying mechanism 21 through the loading mechanism 22, and the product to be shaped is transferred to the shaping mold frame through the conveying mechanism 21, and the shaping is achieved through the cooperation of the press and the shaping mold frame; after the shaping is completed, the shaped product is transferred out through the conveying mechanism 21, and other parts to be shaped are transferred to the shaping mold frame to continue the shaping operation; the shaped product on the conveying mechanism 21 is taken out and placed in the material frame or enters the next step through the unloading mechanism 23.

[0053] Furthermore, the conveying mechanism 21 is mainly used for conveying products, so it can be implemented in a variety of ways, and preferably adopts the following push-boat structure:

[0054] like Fig.12 As shown, the conveying mechanism 21 includes an annular track 210 and a ferrule 211, and the product is fixed by the ferrule 211. The annular track 210 is fixed on the frame 20, and the ferrule 211 is located in the annular track 210 and can move along the annular track 210; a push cylinder 212 is provided at the turning point of the annular track 210, and the push cylinder 212 pushes the ferrule 211 to move along the annular track 210; the cylinder body of the push cylinder 212 is fixedly connected to the annular track 210 or the frame 20.

[0055] During transportation, a plurality of ferrules 211 are placed on the circular track 210 in sequence; the push cylinder pushes one of the ferrules 211 to move, and the ferrule 211 pushes the ferrule 211 in front to move, so that the ferrules 211 can move in sequence. The push cylinder pushes the product to be shaped into the shaping die frame, and then the press is pressed down for shaping. After the shaping is completed, the push cylinder pushes the ferrule 211 to be shaped again to eject the shaped ferrule 211.

[0056] Further, if Fig.15 and 16As shown, the ferrule 211 includes a ferrule body 2110 and a spring pin 2111. A placement through hole 2112 is provided in the middle of the ferrule body 2110. The spring pin 2111 is provided on the ferrule body 2110. One end of the spring pin 2111 can extend into the placement through hole 2112. The product to be shaped is placed in the placement through hole 2112 of the ferrule body 2110. The inner diameter of the placement through hole 2112 is slightly larger than the outer diameter of the product. The spring pin 2111 is used to abut against the product to further fix the product.

[0057] Further, if Fig.10 and 11 As shown, conveyor belts 24 are provided at both the loading mechanism 22 and the unloading mechanism 23. Continuous loading can be achieved through the conveyor belts 24 at the loading mechanism 22; and the transfer of the shaped product can be achieved through the conveyor belts 24 at the unloading mechanism 23.

[0058] Furthermore, the feeding mechanism 22 includes a feeding rack 220, a transverse movement mechanism 221 and a longitudinal movement mechanism 222. The feeding rack 220 is fixedly connected to the frame, the transverse movement mechanism 221 is fixed on the feeding rack 220, and the longitudinal movement mechanism 222 is connected to the transverse movement mechanism 221. The longitudinal movement mechanism 222 is driven to move transversely by the transverse movement mechanism 221. The longitudinal movement mechanism 222 is connected to a finger cylinder 223. The finger cylinder 223 is driven to move longitudinally by the longitudinal movement mechanism 222, and the product is clamped by the finger cylinder 223.

[0059] When loading, the longitudinal movement mechanism 222 moves downward, and the product is clamped by the finger cylinder 223. After clamping, the longitudinal movement mechanism 222 moves upward; then the transverse movement mechanism 221 is used to realize transverse movement to move the product to the conveying mechanism 21, and then the longitudinal movement mechanism 222 moves downward, and the finger cylinder 223 opens its claws to place the product on the conveying mechanism 21.

[0060] The above-mentioned transverse movement mechanism 221 and longitudinal movement mechanism 222 can adopt structures such as linear motors and linear slides in the prior art. Of course, they can also be implemented by cylinders. When using cylinders, it is preferred to use cylinders with guiding functions or guide rails.

[0061] Specifically, taking the cylinder as an example: the transverse movement mechanism 221 is named as the transverse movement cylinder, and the longitudinal movement mechanism 222 is named as the longitudinal movement cylinder; the transverse movement cylinder is connected to the longitudinal movement cylinder by a guide rail, and the longitudinal movement cylinder adopts a cylinder with a guiding function.

[0062] The cylinder body of the transverse moving cylinder is fixed on the loading rack 220, and the piston rod of the transverse moving cylinder is connected to the cylinder body of the longitudinal moving cylinder through the slide on the guide rail (the guide rail and the slide are slidably connected). The guide rail is fixedly connected to the loading rack 220, the cylinder body of the longitudinal moving cylinder is fixedly connected to the slide, and the piston rod of the transverse moving cylinder is fixedly connected to the slide. The movement of the slide along the guide rail is driven by the movement of the transverse moving cylinder piston rod; the piston rod of the longitudinal moving cylinder is fixedly connected to the cylinder body of the finger cylinder 223.

[0063] Further, the unloading mechanism 23 includes an unloading frame 230 and an unloading cylinder 231, the unloading frame 230 is fixedly connected to the frame body, and the cylinder body of the unloading cylinder 231 is fixedly connected to the unloading frame 230; a discharge hole 213 is provided at the conveying mechanism 21, and the product is ejected from the discharge hole 213 by the unloading cylinder 231; therefore, a placement through hole 2112 is provided in the middle of the ferrule body 2110. Specifically: after the ferrule 211 moves to the discharge hole 213, the piston rod of the unloading cylinder 231 moves downward to eject it from the ferrule body 2110, and finally falls through the discharge hole 213.

[0064] Further, if Fig.13 and 14 As shown, a buffer cylinder 25 is provided at the discharge hole 213, and a deceleration flap 251 is hinged at the lower end of the buffer cylinder 25. During the falling process, the product first contacts the deceleration flap 251 to push the deceleration flap 251 to move, thereby reducing the kinetic energy of the product falling, playing a role of buffering and deceleration, and avoiding damage to the product due to excessive falling speed. A counterweight block 252 is provided on the deceleration flap 251, and under the gravity of the counterweight block 252, the deceleration flap 251 is closed.

[0065] The above-mentioned loading structure and unloading mechanism 23 can be set into various structures as needed, such as a common robot arm in the prior art.

[0066] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
