Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, specifically a mold for manufacturing new energy vehicle parts. Background Technology

[0002] In the manufacturing process of new energy vehicles, many key components, from interior body parts and charging interface components to battery pack shells, rely heavily on injection molds for precise molding. Their quality directly affects the safety, comfort, and overall performance of new energy vehicles.

[0003] However, existing injection molds have significant problems in actual production: when using direct injection of molten material, unreasonable mold runner design can lead to inconsistent flow paths of molten plastic, uneven temperature distribution can cause different cooling rates in different areas, and differences in material fluidity can further exacerbate resistance changes during filling. These factors combined result in uneven flow of molten plastic when filling the cavity. When molding thin-walled structural parts, local areas may become too thin due to insufficient plastic filling. When molding high-strength material parts, uneven flow can cause uneven internal structure of the material. Such defects can ultimately lead to a decline in the mechanical properties of the product, which may break due to insufficient local strength during demolding. During use, the product is also prone to damage due to insufficient load-bearing capacity, seriously affecting product quality and production yield. Therefore, we propose a new type of mold for manufacturing new energy vehicle parts. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that uneven material flow can easily lead to localized thinning or even fracture in thin-walled parts or high-strength materials.

[0005] To solve the above technical problems, this application provides a new energy vehicle parts manufacturing mold, including a support frame, and a drive frame is fixedly connected to the top of each of the two sets of support frames; A mold unit is disposed between two drive frames. The mold unit includes a main frame disposed between the two drive frames, an injection frame fixedly connected inside the main frame, an injection head fixedly connected to the top of the main frame, the injection head communicating with the injection frame, a main body component disposed on the outer side of the main frame, and a drive component.

[0006] In some embodiments, the main body includes a mounting bracket fixedly connected to the outside of the main frame. A first motor is fixedly connected to the top of the mounting bracket, and a rotating rod is fixedly connected to the drive end of the first motor. One end of the rotating rod is rotatably connected to a rotating shaft. A push rod is slidably inserted into the bottom of the mounting bracket. One end of the push rod is fixedly connected to a U-shaped frame, which is slidably connected to the rotating shaft. The other end of the push rod extends into the main frame.

[0007] In some embodiments, the main body further includes a limiting frame fixedly connected to the inner side of the main frame. A template is provided on one side of the limiting frame. The template is fixedly connected to one end of the push rod. The limiting frame is slidably connected to the push rod. An ejector rod is fixedly connected to one side of the limiting frame. A spring is provided on the outer sleeve of the ejector rod.

[0008] In some embodiments, the ejector rods and springs are configured as four groups, and the four groups of ejector rods and springs are respectively disposed at the four corners of the limiting frame. One end of each of the four ejector rods penetrates the template. The main body components are configured as two groups, and the two groups of main body components are disposed opposite to each other.

[0009] In some embodiments, the drive component includes a connecting plate fixedly connected to the outside of the main frame, a pivot fixedly connected to the outside of the connecting plate, the pivot being rotatably connected to the drive frame, a second motor being provided on one side of the pivot, a chain being engaged at the drive end of the second motor, and a drive wheel being fixedly sleeved on the outside of the pivot, the drive wheel being engaged with the chain.

[0010] In some embodiments, the connecting plate and pivot are configured as two sets, with the two sets of connecting plates and pivots arranged opposite to each other, each corresponding to a different drive frame.

[0011] In some embodiments, a connecting frame is fixedly connected to the top of the main frame, the connecting frame is connected to the injection head, a first screw is threaded into the connecting frame, a sealing plate is slidably connected inside the connecting frame, and the inner end of the first screw is rotatably connected to the sealing plate.

[0012] In some embodiments, a support column is fixedly connected to the top of each of the two drive frames, a rotating plate is rotatably connected between the two support columns, and a ring is fixedly connected inside the rotating plate.

[0013] In some embodiments, the ring is internally threaded with a second screw, the inner end of the second screw is rotatably connected to a clamping ring, and two limiting rods are fixedly connected to the outside of the clamping ring, both of which are slidably inserted into the ring.

[0014] In some embodiments, hydraulic rods are fixedly connected to the inner sides of both sets of support frames, and a base plate is fixedly connected to the drive ends of the two sets of hydraulic rods. A receiving box is fixedly connected to the top of the base plate, and multiple damping struts are fixedly connected between the receiving box and the base plate.

[0015] This invention has at least the following beneficial effects: Start the first motor, which drives the rotating rod to rotate, which in turn drives the rotating shaft to rotate, and then drives the return frame to move, that is, drives the push rod to move, which in turn drives the template to move into the injection frame. The two templates move relative to each other and merge. At this time, the material cools and solidifies between the two templates. Then start the first motor again to drive the template to move outward. While the push rod drives the template to move outward, the ejector rod will push out from the template to eject the finished product, which is convenient for unloading. The second motor is started, which drives the chain to rotate. The chain then drives the drive wheel to rotate, which in turn drives the pivot to rotate, thereby driving the main frame to rotate. The main frame rotates back and forth at a semi-circular angle, which can make the material in the template flow evenly and avoid uneven flow, which could lead to local thinning or even breakage of thin-walled parts or high-strength materials. When the mold unit rotates as a whole, the molten material naturally fills the cavity between the two mold plates under the action of gravity. This is especially useful for thin-walled parts or long-process products, as it can reduce the injection pressure requirement and avoid material degradation and flash defects caused by high-pressure injection.

[0019] Example 1

[0020] Please see Figures 1-8 The present invention provides a technical solution: A mold for manufacturing new energy vehicle parts includes a support frame 1, with a drive frame 2 fixedly connected to the top of each of the two sets of support frames 1. There are four support frames 1, which are divided into two groups.

[0021] like Figure 2 As shown, mold unit 3 is disposed between two drive frames 2. Mold unit 3 includes a main frame 31 disposed between the two drive frames 2. An injection frame 32 is fixedly connected inside the main frame 31. An injection head 33 is fixedly connected to the top of the main frame 31. The injection head 33 communicates with the injection frame 32 and communicates with the two templates 348.

[0022] like Figure 3As shown, a main body component 34 is provided on the outer side of the main frame 31. The main body component 34 includes a mounting bracket 341 fixedly connected to the outer side of the main frame 31. A first motor 342 is fixedly connected to the top of the mounting bracket 341. A rotating rod 343 is fixedly connected to the drive end of the first motor 342. A rotating shaft 344 is rotatably connected to one end of the rotating rod 343. A push rod 345 is slidably inserted into the bottom of the mounting bracket 341. A loop frame 346 is fixedly connected to one end of the push rod 345. The loop frame 346 is slidably connected to the rotating shaft 344. The other end of the push rod 345 extends into the main frame 31. The first motor 342 drives the rotating rod 343 to rotate, which in turn drives the rotating shaft 344 to rotate, and then drives the loop frame 346 to move. That is, it drives the push rod 345 to move, which in turn drives the template 348 to move into the injection frame 32.

[0023] like Figure 4 As shown, the main body 34 also includes a limiting frame 347 fixedly connected to the inner side of the main frame 31.

A spring 3410 is provided on the outer sleeve of the ejector rod 349. By providing the spring 3410, the template 348 and the limiting frame 347 can be buffered to avoid damage caused by hard contact between the template 348 and the limiting frame 347. It should be noted that one end of the ejector rod 349 slides through the template 348.

[0024] The ejector rods 349 and springs 3410 are set in four groups. The four groups of ejector rods 349 and springs 3410 are respectively set at the four corners of the limiting frame 347. One end of each of the four ejector rods 349 passes through the template 348. The main body 34 is set in two groups, and the two groups of main body 34 are set opposite to each other.

[0025] like Figure 5 As shown, the mold unit 3 also includes a driving component 35. The driving component 35 includes a connecting plate 351 fixedly connected to the outside of the main frame 31. A pivot 352 is fixedly connected to the outside of the connecting plate 351. The pivot 352 is rotatably connected to the driving frame 2. A second motor 353 is provided on one side of the pivot 352. A chain 354 is engaged at the driving end of the second motor 353. A driving wheel 355 is fixedly sleeved on the outside of the pivot 352. The driving wheel 355 is engaged with the chain 354. It should be noted that the wrap angle between the driving wheel 355 and the chain 354 is between 120 degrees and 180 degrees to ensure transmission. The chain 354 has appropriate tension and complete engagement.

[0026] The connecting plate 351 and the pivot 352 are set in two groups, with the two groups of connecting plates 351 and pivots 352 arranged opposite to each other, each corresponding to one of the two drive frames 2.

[0027] A connecting frame 4 is fixedly connected to the top of the main frame 31. The connecting frame 4 is connected to the injection head 33.

[0028] Both drive frames 2 are fixedly connected to the top of a support column 7, and a rotating plate 8 is rotatably connected between the two support columns 7. A ring 9 is fixedly connected inside the rotating plate 8.

[0029] The inner thread of the ring 9 is connected to the second screw 10. The inner end of the second screw 10 is rotatably connected to the clamping ring 11. Two limiting rods 12 are fixedly connected to the outside of the clamping ring 11. Both limiting rods 12 are slidably inserted into the ring 9.

[0030] Hydraulic rods 13 are fixedly connected to the inner side of both sets of support frames 1. The drive ends of the two sets of hydraulic rods 13 are fixedly connected to the base plate 14. The top of the base plate 14 is fixedly connected to the receiving box 15. Multiple damping struts 16 are fixedly connected between the receiving box 15 and the base plate 14.

[0031] In use, molten material is injected into the injection frame 32 through the injection head 33. Then, the first motor 342 is started, which drives the rotating rod 343 to rotate, thereby driving the rotating shaft 344 to rotate, which in turn drives the loop frame 346 to move, that is, drives the push rod 345 to move, which in turn drives the template 348 to move into the injection frame 32. The two templates 348 move relative to each other and merge. At this time, the material cools and solidifies between the two templates 348. Then, the first motor 342 is started again, which drives the template 348 to move outward. At the same time that the push rod 345 drives the template 348 to move outward, the ejector rod 349 will push out from the template 348 to eject the finished product. The second motor 353 is started, which drives the chain 354 to rotate. The chain 354 then drives the drive wheel 355 to rotate, which in turn drives the pivot 352 to rotate, thereby driving the main frame 31 to rotate. The main frame 31 rotates back and forth at a semi-circular angle, which can make the material in the template 348 flow evenly.

The loop frame 346 is slidably connected to the rotating shaft 344. The other end of the push rod 345 extends into the main frame 31. The first motor 342 drives the rotating rod 343 to rotate, which in turn drives the rotating shaft 344 to rotate, and then drives the loop frame 346 to move. That is, it drives the push rod 345 to move, which in turn drives the template 348 to move into the injection frame 32.

[0035] like Figure 4 As shown, the main body 34 also includes a limiting frame 347 fixedly connected to the inner side of the main frame 31. A template 348 is provided on one side of the limiting frame 347. The template 348 is fixedly connected to one end of the push rod 345.

[0046] Start the hydraulic rod 13, which drives the base plate 14, receiving box 15 and multiple damping struts 16 to descend as a whole. At this time, space can be left to facilitate the overall rotation of the mold unit 3. After forming, the base plate 14, receiving box 15 and multiple damping struts 16 are driven to rise in the opposite direction, shortening the distance between the receiving box 15 and the main frame 31. At this time, the detached finished product can fall into the receiving box 15 and then be buffered by the multiple damping struts 16.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
