Description

Technical Field

[0001] The invention relates to the technical field of high-frequency connector production and processing, and in particular to a special mold for high-frequency connector production. Background Art

[0002] When high-frequency connectors are produced by injection molding, granular or powdered plastics need to be added to the hopper of the injection molding machine. The plastics are heated and melted in the injection molding machine and kept in a fluid state. Then, they are injected into the closed mold under a certain pressure. After cooling and shaping, the molten plastics solidify into the required plastic parts. At this time, an injection mold is needed.

[0003] A special mold for producing aviation high-frequency connectors disclosed in Chinese patent CN112277256A includes a mother mold and a male mold located below the mother mold; a molding cavity is provided at the bottom of the mother mold, a first plate-shaped insert corresponding to a first slot is inserted in the molding cavity, and a second plate-shaped insert is provided on the side of the first plate-shaped insert; a third plate-shaped insert extending into the molding cavity and needle-shaped inserts corresponding to the third slots at both sides of the partition are provided at the top of the male mold, and the needle-shaped inserts are distributed in groups on the top of the male insert plate; the needle-shaped insert has a molding portion with the same shape as the second slot and a positioning portion for cooperating with the mother mold for positioning the molding portion, and the positioning portion is formed by extending the molding portion in a direction opposite to the third slot and then further extending upward.

[0004] However, compared with the existing technology and the comparative solution, it can be seen that the special mold for producing aviation high-frequency connectors still has the following problems in actual use:

[0005] Due to the presence of protrusions in the mold cavity, the molten plastic will be divided into two molten plastics when it flows to the protrusions in the mold cavity. At the same time, the molten plastic will semi-solidify and move forward in the mold cavity during the injection process. The two molten plastics at the fusion point will not be completely mixed with each other, resulting in a weld mark at the confluence of the molten plastics (the weld mark generally appears at the position of the part away from the injection port, that is, the confluence of the two molten plastics. After the two molten plastics merge, as the two molten plastics are squeezed, the confluence of the two molten plastics adheres to each other). The weld mark will cause marks on the surface of the produced parts, affecting the appearance, and affecting the subsequent painting and electroplating. In severe cases, it will also reduce the strength of the parts. Summary of the invention

[0053] like Figure 5 , Figure 7 , Figure 8 , Fig.18 and Fig.21 As shown, the adjustment assembly 68 includes a third connecting shaft 681, a knob 682 and a third gear 683. The first connecting shaft 661, the second connecting shaft 671 and the third connecting shaft 681 are all rotatably connected to the male mold core 61. The knob 682 is provided at one end of the third connecting shaft 681, and the third gear 683 is provided at one end of the third connecting shaft 681 away from the knob 682. The first gear 664 is meshed with the third gear 683. The first gear 664, the second gear 674, the third gear 683 and the third elastic member 69 are all located inside the receiving groove 64.

[0054] like Figure 2 , Figure 4 and Fig. 22As shown, a female mold core 701 is provided on the female mold plate 7, and the position of the female mold core 701 corresponds to the position of the male mold core 61. A second mold cavity 702 corresponding to the first mold cavity 63 is opened on the female mold core 701, and a receiving groove 703 is opened at a position corresponding to the knob 682 on the female mold core 701;

[0055] like Fig. 22 and Fig.23 As shown, the flow channel plate 8 is provided with an injection port 801 and an injection flow channel 802 , the injection port 801 and the injection flow channel 802 are connected, and the injection flow channel 802 is connected to the second mold cavity 702 .

[0056] The working process is as follows:

[0057] S1. When in use, the hydraulic cylinder 2 is started, and the hydraulic cylinder 2 drives the ejector assembly 5 and the male mold plate 6 to move toward the second fixed plate 10 through the connecting plate 4. When the male mold plate 6 and the female mold plate 7 are molded, the hydraulic cylinder 2 continues to push the connecting plate 4, and the connecting plate 4 pushes the female mold plate 7 through the male mold plate 6, so that the female mold plate 7 contacts the runner plate 8, and the first elastic member 9 contracts to complete the mold closing (such as Figure 1 shown);

[0058] S2, the injection molding machine then injects the molten plastic from the injection port 801, and the molten plastic flows into the second mold cavity 702 along the injection flow channel 802, and then flows into the first mold cavity 63 along the second mold cavity 702;

[0059] S3. Due to the protruding portion on the male mold core 61, the molten plastic is divided into two strands. When the two strands of molten plastic flow to the first mark-eliminating component 66 and the second mark-eliminating component 67, the two strands of molten plastic push the first paddle 663 and the second paddle 673 respectively. The first paddle 663 and the second paddle 673 drive the first connecting shaft 661 and the second connecting shaft 671 to rotate through the first rotating block 662 and the second rotating block 672 respectively. The first connecting shaft 661 and the second connecting shaft 671 drive the first eccentric member 665 and the second eccentric member 6666 and the second eccentric member 667 through the first gear 664 and the second gear 674 respectively. The eccentric member 675 rotates, and since the first gear 664 and the second gear 674 are meshed, the first paddle 663 and the second paddle 673 rotate at the same angle, and the first eccentric member 665 and the second eccentric member 675 rotate at the same angle. During the rotation of the first eccentric member 665 and the second eccentric member 675, the third elastic member 69 is stretched. At this time, since the elasticity of the third elastic member 69 needs to be overcome, the rotation speed of the first paddle 663 and the second paddle 673 is relatively slow, and some molten plastic will flow between adjacent first paddles 663 or adjacent second paddles 673;

[0060] S4. When the first eccentric member 665 and the second eccentric member 675 rotate through the maximum distance between them, the force generated by the contraction of the third elastic member 69 and the thrust of the two molten plastics on the first paddle 663 and the second paddle 673 drive the first paddle 663 and the second paddle 673 to rotate (the states of the first mark-eliminating component 66 and the second mark-eliminating component 67 change from Figures 7 to 9 Switch to Figures 11 to 13 ), at this time, the rotation speeds of the first paddle 663 and the second paddle 673 are relatively fast, and the first paddle 663 and the second paddle 673 that are staggered with each other mix the two streams of molten plastics with each other;

[0061] S5. When the two streams of molten plastic meet, the thrust of the two streams of molten plastic on the first paddle 663 and the second paddle 673 disappears. At this time, the third elastic member 69 continues to contract. During the contraction process, the third elastic member 69 drives the first gear 664 and the second gear 674 to rotate respectively through the first eccentric member 665 and the second eccentric member 675. The first gear 664 and the second gear 674 drive the first rotating block 662 and the second rotating block 672 to rotate respectively through the first connecting shaft 661 and the second connecting shaft 671. The first rotating block 662 and the second rotating block 672 drive the first paddle 663 and the second paddle 673 to continue to rotate until the first rotating block 662, the second rotating block 672, the first paddle 663 and the second paddle 673 are received into the connecting grooves provided in the first mold cavity 63 and matched with the first rotating block 662, the second rotating block 672, the first paddle 663 and the second paddle 673 (the state of the first trace eliminating component 66 and the second trace eliminating component 67 is changed from Figures 11 to 13 Switch to Figures 15 to 17 ), complete the mixing of the two streams of molten plastics while avoiding affecting the cooling and molding of the molten plastics;

[0062] S6, after the molten plastic in the first mold cavity 63 and the second mold cavity 702 is cooled and formed into a connector component, the hydraulic cylinder 2 drives the ejector assembly 5 and the male mold plate 6 to move toward the first fixed plate 1 through the connecting plate 4, and the first elastic member 9 rebounds, driving the female mold plate 7 to leave the runner plate 8, so as to facilitate cleaning of the cooled and formed injection runner 802;

[0063] S7. As the connecting plate 4 moves, after the ejector rod 505 abuts against the ejector column 3, the hydraulic cylinder 2 continues to drive the connecting plate 4 to move toward the first fixed plate 1. The ejector rod 505 drives the ejector panel 501 and the connecting plate 4 to move relative to each other through the ejector bottom plate 502. The second elastic member 504 contracts, and the ejector panel 501 drives the ejector pin 503 to eject the formed connector part from the male template 6, completing the unloading (such as Figure 2 shown);

[0064] S8. When it is necessary to inject the mold again, rotate the knob 682, the knob 682 drives the third gear 683 to rotate through the third connecting shaft 681, the third gear 683 drives the second gear 674 to rotate through the first gear 664, and the first paddle 663 and the second paddle 673 are turned out of the connecting groove (the state of the first mark-eliminating component 66 and the second mark-eliminating component 67 is changed from Figures 15 to 17 Switch to Figures 7 to 9 ), then start the hydraulic cylinder 2, and after the mold is closed, injection molding can be carried out through the injection port 801.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
