Abstract
Description
Technical Field
[0001] This utility model relates to the field of molding die technology, specifically to a molding die for irregularly shaped plastic parts. Background Technology
[0002] Injection molding of irregularly shaped plastic parts is a manufacturing process that uses an injection molding machine to inject molten plastic material into specially designed molds with specific shapes and dimensions 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 irregularly shaped plastic parts, such as automotive parts and electronic product housings. Through cooling and solidification, the final product has excellent physical properties and stable dimensional accuracy.
[0003] During the injection molding process, heated and molten plastic granules are poured into the mold and precisely introduced into the mold through the injection tube, with the aim of making them fit tightly against the inner wall of the mold. However, given that the plastic parts to be produced are irregularly shaped, the molten plastic often cannot completely fill all corners and complex structures of the mold. This not only reduces the quality of the plastic parts molding, but also significantly affects the overall efficiency of injection molding of irregularly shaped plastic parts.
[0004] Therefore, a molding die for irregularly shaped plastic parts is proposed to address the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a molding die for irregularly shaped plastic parts, including a mounting base plate, a mounting frame above the mounting base plate, a rotating motor inside a placement cavity of the mounting frame, a rotating shaft connected above the rotating motor, the rotating shaft passing through the mounting base plate and extending above the mounting base plate to connect with a rotating disk, sliding blocks on both sides below the rotating disk, the sliding blocks slidingly disposed in a circular groove above the mounting base plate, a lower mold above the rotating disk, an upper mold correspondingly disposed above the lower mold, an electric telescopic rod at the center above the upper mold, driven telescopic rods on both sides of the electric telescopic rod, a rotating disk II above the electric telescopic rod and the driven telescopic rods, a rotating shaft II at the center above the rotating disk II, a bearing seat above the rotating shaft II, and sliding blocks on both sides above the rotating disk II, the sliding blocks slidingly disposed in a circular groove at the top of the mounting frame.
[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0007] This invention comprises a rotating motor, a rotating shaft, a rotating disk, a sliding block, and a circular groove. The rotating motor drives the rotating shaft to rotate, which in turn drives the rotating disk to rotate. The rotating disk then causes the sliding blocks on both sides below to slide within the circular groove. The rotation of the lower mold allows the injection molding material to be evenly filled into the mold cavity, thus improving the quality of the injection molding.
[0008] This invention achieves a tight connection between the upper and lower molds by setting insert blocks on both sides below the upper mold and opening slots on both sides above the lower mold, with the insert blocks inserted into the slots.
[0009] This utility model is designed with a rotating disk, a sliding block, and a circular groove. The rotating disk rotates, causing the sliding block to rotate within the circular groove, thus allowing the upper mold to rotate with the lower mold, which facilitates the uniform filling of the upper mold with the injection plastic.

[0015] As attached Figure 1 , 2As shown, this utility model provides a molding die for irregularly shaped plastic parts, including a mounting base plate 1, a mounting frame 2 above the mounting base plate 1, a rotating motor 6 inside a placement cavity 101, a rotating shaft 5 connected to the top of the rotating motor 6, the rotating shaft 5 passing through the mounting base plate 1 and extending to the top of the mounting base plate 1 to connect with a rotating disk 4, and sliding blocks 7 on both sides below the rotating disk 4. The sliding blocks 7 are slidably disposed in a circular groove 102 opened above the mounting base plate 1. The rotation of the rotating disk 4 drives the sliding blocks 7 on both sides to slide in the circular groove 102. The rotation of the lower mold 8 can drive the injection plastic to fill the mold cavity evenly, improving the injection molding quality. A lower mold 8 is provided above the rotating disk 4. Mold 8, with an upper mold 9 positioned above the lower mold 8. An electric telescopic rod 11 is positioned at the center of the upper mold 9, with driven telescopic rods 12 on both sides of the electric telescopic rod 11.

The sliding blocks 16 are slidably positioned within a circular groove 201 opened at the top of the mounting frame 2. The rotation of the rotating disk 13 causes the sliding blocks 16 to rotate within the circular groove 201, thereby allowing the upper mold 9 to rotate with the lower mold 8, facilitating the even filling of the upper mold with injection plastic.
[0016] Specifically, the lower mold 8 has a mold cavity 801 inside, and slots 802 are respectively opened on both sides above the mold cavity 801.
[0017] Specifically, the upper mold 9 has a mold cavity 901 inside, and the lower sides of the upper mold 9 are respectively provided with insert blocks 10.

[0019] Specifically, a control panel 3 is provided on the outer front surface of the mounting base plate 1, and the control panel 3 is electrically connected to the rotating motor 6 and the electric telescopic rod 11.
[0020] Working principle: During use, the electric telescopic rod 1 extends, causing the upper mold 9 to move downwards and approach the lower mold 8. At this time, the insert block 10 is inserted into the slot 802, injecting the plastic into the mold cavity. Then, the motor 6 rotates, causing the rotating shaft 5 to rotate. The rotating shaft 5 rotates, causing the rotating disk 4 to rotate. The rotating disk 4 rotates, causing the sliding blocks 7 on both sides below to slide in the circular groove 102. The rotation of the lower mold 8 causes the upper mold 9 to rotate, thereby evenly filling the mold cavity and improving the quality of injection molding.
