Description

Technical Field

[0001] The utility model relates to the technical field of metal injection molding, in particular to a parallel double-injection magnesium alloy semi-solid molding machine. Background Art

[0002] Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: density of about 1.8g / cm3, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to organic and alkali corrosion. Its combined alloy elements include aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium. The most widely used is magnesium-aluminum alloy, followed by magnesium-manganese alloy and magnesium-zinc-zirconium alloy. It is mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors.

[0003] At present, magnesium alloy products are widely used in automobile-related fields. They are injected into products such as seat frames and vehicle-mounted screen brackets through magnesium alloy semi-solid injection molding machines. The weight of the products is about 3-4kg.

[0004] However, with the development of technology, magnesium alloy products are not limited to small parts, but are beginning to be used in automobile door panels. The weight of automobile door panels is much greater than 5kg. According to conventional calculations in the semi-solid industry, a product with a net weight of 5kg requires a molding device with an injection capacity of more than 13kg. However, the existing technology, such as the single injection molding device with application number CN202310709128.4 and the name of a metal injection molding device, generally cannot achieve an injection volume of more than 13kg. Therefore, it is necessary to introduce a dual injection molding device to achieve the molding of heavier products.

[0005] When a dual-injection molding device is used to perform injection molding on a dual-feed port mold, it is difficult for general dual-injection molding devices to complete injection molding on different molds due to the different spacing and heights of the feed ports of different molds.

[0006] Based on the above problems, a parallel double-injection magnesium alloy semi-solid forming machine is designed. Its double injection nozzles can adjust the horizontal distance and vertical height to adapt to the forming of products in different molds. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0032] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0033] like Figure 1-Figure 4 As shown, a parallel double-injection magnesium alloy semi-solid molding machine includes a fixed seat 1, a horizontal driving member 2, a first slide rail slider assembly 3, an injection molding mechanism 4 and a head plate 5, the injection molding mechanism 4 includes a nozzle 425 and a whole-movement connecting rod 414, and the head plate 5 includes a long hole 51 for adapting the nozzle 425;

[0034] A plurality of first slide rail and slider assemblies 3 arranged longitudinally are installed on the fixing seat 1. The first slide rail and slider assemblies 3 include a slide rail at the bottom and a slider on the slide rail. Two injection molding mechanisms 4 arranged transversely are installed on the first slide rail and slider assemblies 3.

[0035] At least two horizontal driving members 2 are installed on the front and rear sides of the fixing seat 1, and the driving rods of the horizontal driving members 2 are fixedly connected to a side of the injection molding mechanism 4 facing the horizontal driving members 2;

[0036] The horizontal driving member 2 can drive the injection molding mechanism 4 to move longitudinally along the fixed seat 1. Accordingly, when the horizontal driving member 2 drives the injection molding mechanism 4 to move longitudinally, the nozzle 425 on the injection molding mechanism 4 also moves forward and backward in the long hole 51.

[0037] The injection molding mechanism 4 is fixedly connected to the head plate 5 via a fully movable connecting rod 414 .

[0038] When the mold is replaced, the distance between its feed ports is different. Since the injection molding mechanism 4 in the utility model is two sets and is parallel, the horizontal positions of the two injection molding mechanisms 4 can be adjusted separately, thereby adjusting the positions of the two nozzles 425 to adapt to molds with different distances to meet production needs.

[0039] The length and width of the long hole 51 are greater than those of the nozzle 425 . The nozzle 425 can move forward and backward and up and down in the long hole 51 to adapt to different feed ports with different mold spacings.

[0040] The injection molding mechanism 4 includes an upper bracket 41 and an injection body 42 . The injection body 42 is installed at the upper end of the upper bracket 41 . The injection body 42 can move along the upper bracket 41 toward the head plate 5 .

[0041] The upper bracket 41 includes a bracket 411, a second slide rail slider assembly 412, an entire shift cylinder 413 and an entire shift connecting rod 414. The second slide rail slider assembly 412 is installed at the front and rear ends of the bracket 411. The second slide rail slider assembly 412 includes a bottom slide rail and a slider located on the slide rail. The entire shift cylinder 413 and an entire shift connecting rod 414 are installed in the middle part of the bracket 411. The entire shift connecting rod 414 is installed at the front end of the entire shift cylinder 413. The head of the entire shift connecting rod 414 is T-shaped. The upper end of the entire shift cylinder 413 is fixedly connected to the lower end of the injection cylinder mechanism 423.

[0042] When the whole-moving oil cylinder 413 is in motion, since the whole-moving oil cylinder 413 is connected to the injection oil cylinder mechanism 423 , the whole-moving oil cylinder 413 will drive the injection body 42 to move toward or away from the head plate 5 .

[0043] The injection body 42 includes an injection seat bracket 421, a driving mechanism 422, an injection cylinder mechanism 423, a feeding mechanism 424 and a nozzle 425. The injection seat bracket 421 is installed on the second slide rail slider assembly 412. The injection seat bracket 421 is sequentially installed with the nozzle 425, the feeding mechanism 424, the injection cylinder mechanism 423 and the driving mechanism 422 in the direction of the head plate 5.

[0044] More specifically, the injection cylinder mechanism 423 includes an injection cylinder and an integrated piston and piston rod, and the feeding mechanism 424 includes a feeding screw and a storage drive mechanism;

[0045] When the injection body 42 injects, oil enters the injection cylinder from the oil inlet side and exits from the oil outlet side, and the oil pushes the integrated piston and piston rod to move leftward, and pushes the feeding screw to move leftward, so that the nozzle 425 can eject the magnesium alloy material;

[0046] When the injection body 42 stores material, the material storage driving mechanism drives the feeding screw to rotate. At the same time, the original oil outlet side becomes the oil inlet side for oil inlet, and the original oil inlet side becomes the oil outlet side for oil outlet. In conjunction with the auxiliary ejection, the feeding screw moves to the right, realizing the compound action of the feeding screw moving to the right and rotating, thereby smoothly feeding the feeding screw.

[0047] A moving fixing block 8 is set below the head plate 5, and T-shaped grooves 81 adapted to the head of the moving connecting rod 414 are formed on both sides of the moving fixing block 8. When the moving fixing block 8 is not completely fixed to the head plate 5, the head of the moving connecting rod 414 can move back and forth in the T-shaped groove 81. The moving connecting rod 414 moves back and forth in the T-shaped groove 81 to coordinate with the movement of the two nozzles 425.

[0048] The head plate 5 includes a plurality of mounting holes 52 for connecting with the entire movable fixing block 8 , and the mounting holes 52 are located at the lower end of the long hole 51 .

[0049] The whole-movement fixing block 8 is fixedly connected to the head plate 5 via the mounting hole 52 , that is, bolts pass through the whole-movement fixing block 8 and the mounting hole 52 to fix the whole-movement fixing block 8 on the head plate 5 .

[0050] A vertical driving member 6 is also provided at the bottom of the fixed seat 1. The top of the driving rod of the vertical driving member 6 is connected to the side of the fixed seat 1 facing the vertical driving member 6. The vertical driving member 6 can drive the fixed seat 1 to move up and down. When the vertical driving member 6 wants to move the fixed seat 1, the whole moving fixed block 8 is removed from the head plate 5. When the vertical driving member 6 moves the fixed seat 1 to the specified position, the whole moving fixed block 8 is connected to a group of mounting holes 52 of the head plate 5 to complete the fixed connection between the injection molding mechanism 4 and the head plate 5.

[0051] Furthermore, after the vertical driving member 6 raises the fixing seat 1 to a specified position, a support block is placed below the fixing seat 1, and the support block is used to support the fixing seat 1 raised by the vertical driving member 6. After the fixing seat 1 is raised, the vertical driving member 6 can be removed.

[0052] A vertical driving member 6 and a support block are arranged at the lower part of the fixing seat 1 of the utility model. After the vertical driving member 6 lifts the fixing seat 1, the fixing seat 1 is supported by the support block, so that the height position of the nozzle 425 can be adjusted.

[0053] The horizontal driving member 2 and the vertical driving member 6 in the utility model can be a cylinder or a lead screw, and the specific standard parts used are selected according to actual needs.
