[0047] Please refer toFigure 1-13 , the present utility model provides a technical solution: a mold capable of improving the surface quality of the feeding, including an upper fixing plate 1, a lower fixing plate 8 and an upper support plate 14.

[0049] Specifically, the length and width of the active plate 2 respectively match the length and width of the inner side of the bottom of the upper fixing plate 1.

[0050] Three of the end faces of the T-shaped frame 5 are respectively provided with wheel grooves 6, pulleys 7 are rotatably installed inside the wheel grooves 6, and the pulleys 7 are in sliding contact with the inner wall surface of the upper fixing plate 1. Specifically, through the rolling action of the pulleys 7, the friction force during the feeding and demolding processes of the mold is reduced, ensuring the smooth operation of the mold. The sliding contact between the pulleys 7 and the inner wall surface of the upper fixing plate 1 not only improves the stability of the mold, but also reduces the wear of the mold and extends the service life of the mold. In addition, the design of the T-shaped frame 5 and the pulleys 7 makes the mold more flexible during operation, facilitating adjustment and maintenance, and improving production efficiency and operation convenience.

[0051] A thimble bottom plate 9 is fixedly connected to the top of the lower fixing plate 8, a thimble panel 10 and several groups of thimbles 11 are fixedly connected to the top of the thimble bottom plate 9, several groups of thimbles 11 penetrate through the thimble panel 10, square irons 21 are fixedly connected to both sides of the top of the lower fixing plate 8, the two groups of square irons 21 are respectively arranged on both sides of the thimble bottom plate 9 and the thimble panel 10, and a lower support plate 12 is connected to the top of the two groups of square irons 21. A lower core material 13 is fixedly arranged inside the top of the lower support plate 12, and a third mounting plate 18 is fixedly connected to the top of the lower core material 13.

[0052] The upper support plate 14 is connected to the bottoms of the upper fixing plate 1 and the active plate 2, an upper core material 15 is fixedly connected to the inside of the upper support plate 14, a first mounting plate 16 and a second mounting plate 17 are fixedly connected in sequence to the bottom of the upper core material 15, several groups of end pipe grooves 19 are opened inside the upper core material 15, and several forming grooves 20 are penetrated and opened inside the second mounting plate 17.

[0053] Specifically, the first mounting plate 16, the second mounting plate 17 and the third mounting plate 18 are all detachable and replaceable. According to the actual use requirements, the shape of the forming groove 20 inside the second mounting plate 17 can be prefabricated, so as to be applicable to various shapes of injection molding and meet the production requirements of different products, having a wide application prospect.

[0054] The branch feeding mechanism 4 includes a receiving pipe 401, an H-shaped pipe 402, four groups of X-shaped pipes 403 and sixteen groups of branch end pipes 404, wherein:

[0055] The receiving pipe 401 is fixed to the inner side of the movable plate 2, and the receiving pipe 401 is connected to the injection core 3;

[0056] The H-shaped pipe 402 is fixedly embedded in the bottom of the movable plate 2, and the H-shaped pipe 402 is fixedly connected to the bottom of the receiving pipe 401;

[0057] Four groups of X-shaped pipes 403 are respectively fixedly connected to the ends of the H-shaped pipe 402;

[0058] Sixteen groups of branch end pipes 404 are respectively fixedly connected to the bottoms of the X-shaped pipes 403.

[0059] Specifically, referring to the attached Figure 2 and the attached Figure 4 of the specification, through the connection between the receiving pipe 401 and the injection core 3, the preliminary distribution of the injection material is realized. After the material is input from the injection core 3, it is first injected into the H-shaped pipe 402 through the receiving pipe 401, and then the H-shaped pipe 402 further distributes the injection material into the four groups of X-shaped pipes 403. Each group of X-shaped pipes 403 then evenly distributes the injection material into each forming groove 20 of the mold through the four groups of branch end pipes 404 connected below it. This multi-level injection material distribution design effectively avoids the problems of air bubbles and flow marks during the injection process, ensures the uniformity and stability of the injection material, and through this optimized injection mechanism design, the mold not only improves the surface quality of the product, but also significantly improves the production efficiency and the product qualification rate.

[0060] Specifically, referring to the attached Figure 2 of the specification, the lower end of the injection core 3 is tightly sleeved on the outside of the receiving pipe 401, and the injection core 3 and the receiving pipe 401 are of a detachable design.

[0061] The outer diameter length and inner diameter length of the branch end pipe 404 both decrease regularly from top to bottom. Several groups of branch end pipes 404 are respectively movably connected to several groups of end pipe grooves 19, and the end pipe grooves 19 are adapted to the shape of the branch end pipes 404. Specifically, referring to the attached Figure 4 and the attached Figure 8 of the specification, through the gradually decreasing structure of the inner cavity of the branch end pipe 404, the fluidity and uniformity of the injection material when injecting into the mold are ensured, and the problems of blockage and uneven distribution during the injection process are avoided. The adaptation of the shape of the branch end pipe 404 and the end pipe groove 19 ensures the sealing and stability during the injection process, further improving the surface quality of the product. The gradually decreasing structure on the outer surface of the branch end pipe 404 makes it easier for the branch end pipe 404 to be inserted and connected to the end pipe groove 19 during mold closing.

[0062] The ejector pin 11 is movably inserted through the lower support plate 12, the lower core material 13, and the third mounting plate 18, and the top of the ejector pin 11 extends into the forming groove 20. Specifically, refer to the appended drawings of the specification Figure 2 and the appended drawings of the specification Figure 11-13 . Through the movable insertion of the ejector pin 11, the smooth demolding of the formed product is achieved, reducing the surface defects of the product. The design of the ejector pin 11 not only improves the efficiency of the demolding process but also reduces the damage to the product during demolding, ensuring the integrity and aesthetics of the product.

[0063] Specifically, refer to the appended drawings of the specification Figure 8 . A corresponding groove for connecting the lower part of the branch injection mechanism 4 is provided inside the top of the upper core material 15.

[0064] Specifically, during use, the upper fixing plate 1, the movable plate 2, the lower support plate 12, and the upper support plate 14 can be respectively connected to corresponding cylinder control devices to achieve mold opening and closing. A top hole for the cylinder to pass through is provided through the center of the lower fixing plate 8, so that the cylinder can push the bottom of the ejector pin 9. The control of mold opening and closing of the mold is already an existing technology and will not be elaborated here.

[0065] Specifically, the injection core 3 evenly distributes the injection material to each part of the mold through the branch injection mechanism 4 at the bottom of the movable plate 2, avoiding problems such as air bubbles and flow marks caused by uneven injection in traditional molds. In addition, the ejector pin bottom plate 9 and the ejector pin panel 10 on the top of the lower fixing plate 8 achieve the smooth demolding of the formed product through a number of ejector pins 11, reducing the surface defects of the product. This mold structure improves the surface quality and production efficiency of the product by optimizing the injection and demolding processes.

[0066] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
