Description

Technical Field

[0001] The utility model relates to the technical field of shaping devices, in particular to a shaping device for preventing injection molded parts from warping and deforming. Background Art

[0002] Injection molding is a method of producing industrial products, usually using rubber injection molding and plastic injection molding. Injection molding can generally be divided into injection molding and die casting. Injection molding is achieved by injection molding machines and molds, and injection molded parts refer to rubber injection molding parts or plastic injection molding parts. Generally, during injection molding, injection molded parts are prone to deformation, which easily increases the rework rate and increases production costs. Therefore, injection molded parts need to be shaped during processing. There are many kinds of shaping devices currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, a general shaping device pours the heated molten injection material directly into a mold for pressing and cooling. After the injection molded part is formed, the operator directly takes the injection molded part out, which can easily generate a pulling force on the injection molded part and directly cause the injection molded part to deform. At the same time, after the molten injection material enters the mold, there is no pressing step, which will cause gaps to remain inside the injection molded part during injection molding, which will also cause the injection molded part to warp and deform. In addition, it is very inconvenient to take the injection molded part after molding, which will increase the time cost of production. Therefore, we propose a shaping device to prevent the injection molded part from warping and deformation, so as to solve the above problems. Utility Model Content

[0017] 2. A rack, a fixing frame, a cylindrical pin and a rotating disk are provided. After the injection molded part is pressed and cooled inside the lower mold, if the operator directly takes out the injection molded part, it is easy to generate a pulling force on the injection molded part, which directly causes the injection molded part to deform.

Since the cylindrical pin is meshed with the rack, that is, when the cylindrical pin rotates, the rack will move up and down inside the fixed frame. The rack is connected to the bottom plate, that is, when the rack moves downward, the bottom plate will also leave from the bottom of the lower mold and move downward, that is, the bottom plate is separated from the lower mold, which is convenient for taking out the molded injection molded parts above the bottom plate, reducing the pulling force of the operator to take the injection molded parts, and ensuring that the injection molded parts will not be warped or deformed;

[0027] like Figure 1 , Figure 3 and Figure 4As shown in the figure, a lower mold 2 and an upper mold 3 are installed on the upper part of the operating table 1, and sliding grooves 4 are symmetrically opened on the left and right sides of the upper mold 3. A top plate 5 is slidably installed inside the sliding groove 4. In addition, a feed port is installed on the upper left of the top plate 5. By opening the valve in the feed port, the molten injection plastic can be transported to the lower mold 2 and the upper mold 3. After the injection plastic enters the lower mold 2, an electric telescopic rod 6 is installed on the upper middle part of the top plate 5. By opening the electric telescopic rod 6, the output end of the electric telescopic rod 6 can push the top plate 5 to move downward, and the top plate 5 can move to the upper part of the lower mold 2, so that the injection plastic can be firmly pressed, so that when the injection molded part is formed, there will be no gap inside, which is convenient for better shaping of the injection molded part.

[0028] like Figure 1 , Figure 3 and Figure 5 As shown in , after the injection molded part is pressed and cooled inside the lower mold 2, the top plate 5 presses the injection plastic, so the top plate 5 is not easy to separate from the injection molded part, that is, knocking rods 13 are symmetrically arranged on the left and right sides above the top plate 5, and the knocking rods 13 are located inside the fixed block 14. At the same time, a connecting frame 15 is fixedly connected to the top of the knocking rod 13, and a sliding block 16 is slidably connected to the inside of the connecting frame 15. In addition, a connecting rod 17 is installed in front of the sliding block 16, and a small motor 18 is connected to the upper front end of the connecting rod 17. When the small motor 18 is turned on, the small motor 18 can make the connecting rod 17 rotate.

In addition, a motor body 12 is connected to the right end of the middle part of the rotating disk 11. When the motor body 12 is turned on, the motor body 12 can make the rotating disk 11 rotate. When the rotating disk 11 rotates, the cylindrical pin 10 is meshed and connected to the left side of the rotating disk 11. The pin 10 will also rotate together. Since the cylindrical pin 10 is meshed with the rack 8, that is, when the cylindrical pin 10 rotates, the rack 8 will move up and down inside the fixed frame 9. The bottom plate 7 is connected above the rack 8, that is, when the rack 8 moves downward, the bottom plate 7 will also leave from the bottom of the lower mold 2 and move downward, that is, the bottom plate 7 is separated from the lower mold 2, making it easy to take out the injection molded parts above the bottom plate 7, reducing the pulling force of the operator to take the injection molded parts, and ensuring that the injection molded parts will not warp or deform.
