Description

Technical Field

[0001] The invention relates to the technical field of injection molding equipment, and in particular to an injection molding equipment for molding special-shaped plastic parts. Background Art

[0002] Injection molding of special-shaped plastic parts is a manufacturing process that uses an injection molding machine to inject molten plastic material into specially designed molds with special shapes and sizes to produce plastic parts with complex shapes and unique appearances. This process can accurately replicate the shape of the mold and is suitable for manufacturing various special-shaped plastic parts, such as automotive parts, electronic product housings, etc. Through cooling and solidification, the final product has excellent physical properties and stable dimensional accuracy.

[0003] During the injection molding process, heated and melted plastic particles are poured into the mold and accurately introduced into the mold through the injection tube in order to achieve a tight fit with the inner wall of the mold. However, given that the plastic parts to be produced are of special-shaped designs, the melted plastic is often difficult to completely fill every corner and complex structure of the mold, which not only reduces the quality of the plastic parts molding, but also significantly affects the overall efficiency of the injection molding of special-shaped plastic parts.

[0004] For example, the "injection molding equipment" disclosed in the Chinese invention patent (application number: 202011053171.2) has a specification that discloses: However, in the conventional technology, in order to speed up the cooling of the plastic in the product cavity, a cooling channel is set on the mother mold. However, the cooling channel generally only extends linearly and has long strip-shaped grooves of the same depth, which leads to uneven cooling of the plastic. The outer surface of the plastic product may have problems such as joint lines, stress marks, or air marks, which makes it difficult to meet the cooling requirements of plastic products with large and complex outer surfaces, thereby affecting the quality of the plastic products. The above patents can prove the defects of the prior art.

As the cross bar 308 moves downward, the auxiliary telescopic rod 312 contracts, and the conduit 311 is pressed out to contact the injection molding tube 215 above the mold. The auxiliary telescopic rod 312 continues to contract, and the pressing plate 309 moves downward, squeezing the melted plastic in the square cone bin 302 out and into the two half-frame molds 214. During the up and down reciprocating movement of the vertical frame 206, the cross bar 308 is simultaneously driven to follow the up and down movement, and the auxiliary telescopic rod 312 cooperates with the pressing plate 309 to stir the heated and melted plastic in the square cone bin 302 to make it melt evenly.

The air in the arc air box 402 is extruded and discharged by the air guide pipe 403. In the process of the vertical frame 206 moving up and down, the mold is also driven to rotate back and forth. As the air is continuously guided to the mold, the mold also rotates continuously, and the mold after injection molding is quickly cooled.

[0054] During the up and down movement of the vertical frame 206, with the cooperation of the sleeve plate 404, the piston rod 408 is continuously driven to reciprocate and rise and fall in the air cylinder 405, and the air is continuously pushed toward the arc-shaped air box 402, and discharged through the air guide pipe 403 on the surface of the arc-shaped air box 402, so that the mold can be cooled by air during the material equalization process, thereby improving the cooling and forming efficiency of the plastic parts.

The positioning rotating frame 406 is used to cooperate with the air cylinder 405 to be driven by the vertical frame 206 to offset, thereby ensuring the stability of the air cylinder 405 during the working process.

[0057] Further, such as Figure 1 As shown, four curved frame plates 6 are evenly distributed and fixedly connected in a rectangular shape below the bottom plate 5, and an inclined frame 7 is fixedly connected to the curved frame plate 6. The other end of the inclined rod 301 is fixedly installed below the bottom plate 5, and the curved frame plate 6 and the inclined frame 7 cooperate with each other to position and support the overall structure.

[0058] The use process of the special-shaped plastic part molding injection molding equipment provided by the present invention is as follows:

[0059] Working principle: The staff splices two half-frame molds 214 to form an integral structure, and the semi-circular rods 201 at both ends are also spliced ​​to form round rods, which are placed above the support frame 208 on the inner wall of the frame;

[0060] Melting material: Pour the plastic particles into the square cone bin 302, start the heating tube 307, heat the plastic particles in the square cone bin 302 to melt them, and then start the electric telescopic rod 304. With the cooperation of the auxiliary plate 303, the cross bar 308 is driven to move up and down, and the vertical frame 206 under the fixed rotating frame 313 follows the movement, and the sliding rod 203 moves up and down in the upper half of a vertical groove of the U-shaped groove 204. The cross bar 308, driven by the auxiliary telescopic rod 312, stirs the pressing plate 309 up and down in the square cone bin 302, so that the plastic particles are evenly stirred and heated;

[0061] Injection molding: After heating is completed, the electric telescopic rod 304 is started again. With the cooperation of the fixed rotating frame 313, the vertical frame 206 moves downward to drive the auxiliary plate 303 to follow the movement, so that the cross bar 308 between the two auxiliary plates 303 moves downward, driving the auxiliary telescopic rod 312 to move downward, so that the lower top of the cone rod 310 connected to the lower end of the auxiliary telescopic rod 312 contacts the upper ends of the plurality of conduits 311. As the cross bar 308 moves downward, the auxiliary telescopic rod 312 contracts, pressing the conduit 311 out of the injection molding above the mold. The auxiliary telescopic rod 312 continues to contract, and the pressing plate 309 moves downward, squeezing the melted plastic in the square cone bin 302 out and into the two half-frame molds 214. The sliding rod 203 on the side of the vertical frame 206 is driven by the electric telescopic rod 304 to hit the double-beveled triangle plate 205 below the U-shaped groove 204, and the limiting rod 210 connected to the double-beveled triangle plate 205 is pushed to move horizontally in the T-shaped groove 209 and approach the side of the sliding rod 203. The deviated double-beveled triangle plate 205 is moved by the limiting rod 210. 10 is rotated about the axis, and at the same time deviates to one side of the slide bar 203. As the slide bar 203 continues to move downward, the elastic telescopic rod 212 is squeezed to shrink, and the support rod 219 connected to the double oblique triangular plate 205 also slides in the anti-arc groove 213. When the slide bar 203 moves to the bottom of the U-shaped groove 204, the double oblique triangular plate 205 reaches a certain tilt state. At this time, the electric telescopic rod 304 is extended, and the elastic telescopic rod 212 pushes the double oblique triangular plate 205 to support the slide bar 203. When the vertical frame 206 is closed, the vertical frame 206 tilts, and then the slide bar 203 is pushed into another vertical slot of the U-shaped slot 204, and the vertical frame 206 is driven to move upward, and then the toothed plate 207 on one side of the vertical frame 206 meshes with the gear 218 on one side of the half-frame mold 214, and the half-frame mold 214 is turned over. Since a ratchet 217 is installed in the middle of the gear 218, the electric telescopic rod 304 contracts, driving the square cone bin 302 to move downward, and the guide tube 311 is inserted into the injection tube 215 at the other end for injection replenishment;

[0062] Even material distribution: During the downward movement of the vertical frame 206, the gear 218 does not rotate with the cooperation of the ratchet 217, while during the upward movement of the vertical frame 206, the gear 218 rotates with the cooperation of the ratchet 217. Then, driven by the continuous lifting of the electric telescopic rod 304, the toothed plate 207 in the vertical frame 206 is always in contact with the gear 218, and does not drive the injection tube 215 to contact the conduit 311, so that the mold after injection molding is continuously rotated, and the melted plastic in the mold is evenly filled on the inner wall of the mold;

[0063] Cooling: When the vertical frame 206 is driven by the electric telescopic rod 304, the piston rod 408 moves up and down in the air cylinder 405 in cooperation with the sleeve plate 404, and the air in the air cylinder 405 is squeezed along the auxiliary pipe 407 and enters the arc air box 402. The air in the arc air box 402 is extruded and discharged from the air guide pipe 403. In the process of the vertical frame 206 moving up and down, the mold is also driven to reciprocate. As the air is continuously guided to the mold, the mold also rotates continuously, and the mold after injection molding is quickly cooled;

[0064] Return: After the injection molding is completed, the slide bar 203 hits the double-bevel triangle plate 205 again. With the cooperation of the elastic telescopic rod 212, the slide bar 203 is pushed back to the original vertical groove of the U-shaped groove 204, and the tooth plate 207 is kept away from the gear 218, so as to prepare for the next injection molding.
