Technical Field

[0001] This utility model relates to the field of graphite processing technology, specifically a demolding device for molded graphite. Background Technology

[0002] Demolding is a crucial step in the molding process of graphite products. Traditional graphite demolding methods have many problems. For example, demolding is difficult for large or complex-shaped graphite products, which can easily lead to damage to the graphite products and affect product quality and production efficiency.

[0003] Existing methods for demolding graphite products have many shortcomings. Most rely on simple mechanical ejection structures. For graphite products with complex shapes, large sizes, or close fit to the mold, this method is often difficult to demold smoothly, which can easily cause local damage or deformation of the product. Furthermore, uneven demolding force may scratch the surface of the product, affecting its appearance and performance.

[0004] To address this issue, the present invention provides a graphite demolding device for compression molding. By setting the molding die into a split structure and using a driving device to achieve relative displacement, the device effectively reduces the binding force on the graphite product during demolding, greatly reduces the demolding difficulty, significantly reduces the probability of damage to the graphite product during demolding, and improves the product yield, thereby solving the aforementioned problems.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1-4 A graphite demolding device for compression molding includes a molding device 1. A fixing component 2 is provided at one end of the upper part of the molding device 1, and a demolding component 3 is provided at the other end of the upper part of the molding device 1. The demolding component 3 includes a first hydraulic column 31 and a second hydraulic column 33. The first hydraulic column 31 is fixedly installed at the center of the top of the molding device 1. A forming block 32 is fixedly connected to the output end of the first hydraulic column 31. There are two sets of second hydraulic columns 33. The two sets of second hydraulic columns 33 are symmetrically arranged on both sides of the molding device 1 and fixedly connected to the molding device 1. The output ends of the two sets of second hydraulic columns 33 are fixedly connected to equal-dividing mold seats 34. A slider 35 is fixedly connected to the bottom end of the equal-dividing mold seats 34. The inner diameter of the forming block 32 matches the inner diameter of the equal-dividing mold seats 34.

[0025] A slide rail 12 is provided at the center of the upper surface of the molding device 1. A centering seat 17 is provided at the center of the slide rail 12. The centering seat 17 is fixedly connected to the molding device 1. Waste discharge grooves 13 are provided on both sides of the interior of the slide rail 12, including the bottom sides of the centering seat 17.

[0026] The molding device 1 has a waste chamber 14 inside, and the waste discharge groove 13 connects the slide 12 to the waste chamber 14.

[0027] The centering seat 17 has inner grooves 18 on both sides of its bottom end. The inner diameter of the slide 12 matches the outer diameter of the slider 35. The slider 35 is slidably connected to the molding device 1.

[0028] A slot 11 is provided on the upper left side of the molding device 1, and a waste drawer 15 is movably connected inside the molding device 1. A groove 16 is provided on the front surface of the waste drawer 15.

[0029] In this embodiment, two sets of equally divided mold seats 34 are combined together. Molding material is added into the interior of the two sets of equally divided mold seats 34. The molding block 32 is driven into the interior of the equally divided mold seat 34 by the first hydraulic column 31 to perform hydraulic molding of the material. After molding, the hydraulic pressure of the first hydraulic column 31 is cut off but the mold remains stationary. The two sets of equally divided mold seats 34 are pulled apart by two sets of second hydraulic columns 33. Because the molding block 32 still exerts some pressure on the top of the molding die, even if the die sticks to the two sets of equally divided mold seats 34 when the two ends of the equally divided mold seats 34 are removed, the two will not move. Then the first hydraulic column 31 drives the molding block 32 to reset, thereby completing the demolding of the die. The setting of slide 12 is used to... The bottom of the equal-dividing mold base 34 is limited to prevent deviation during the merging process, which would cause deviation in mold forming. By opening waste discharge grooves 13 on both sides of the slide 12, including the two sides of the centering seat 17 located at the center of the slide 12, when the equal-dividing mold base 34 moves, the raw material spilled inside the slide 12 is pushed into the waste discharge grooves 13 and falls into the waste material cavity 14. Finally, the waste material is stored through the waste material drawer 15. By opening inner grooves 18 on the bottom of both sides of the centering seat 17, it is prevented that when the slide 35 faces the centering seat 17, some waste material adheres to its surface, which would cause a gap in the middle when the two sets of equal-dividing mold bases 34 are merged, resulting in deviation in mold production.

[0030] Example 2:

[0031] Please see Figure 1-3This embodiment provides a technical solution based on embodiment one: the fixing component 2 includes a fixing slide rail 21, the upper surface of the fixing slide rail 21 is provided with a slide track 22, the inside of the slide track 22 is provided with a movable mounting seat 25 that is slidably connected to the fixing slide rail 21, the right end of the fixing slide rail 21 is fixedly connected to a motor 23, the output shaft of the motor 23 is fixedly connected to a lead screw 24, the lead screw 24 is located inside the slide track 22 and is rotatably connected to the fixing slide rail 21, the lead screw 24 passes through the bottom end of the movable mounting seat 25 and is threadedly connected to the movable mounting seat 25, and the fixing slide rail 21 is fixedly installed on the right side of the molding device 1.

[0032] A release agent spray gun 26 is fixedly installed on the upper end of the movable mounting base 25. A feed port 27 is fixedly connected to the left side of the top of the release agent spray gun 26, and an air inlet 28 is fixedly connected to the right side of the top of the release agent spray gun 26. A connecting pipe 29 is fixedly connected to the output end of the release agent spray gun 26. A nozzle 210 is fixedly connected to the end of the connecting pipe 29 away from the release agent spray gun 26. Nozzles 211 are fixedly connected to the surface of the nozzle 210. There are several groups of nozzles 211, and the nozzles 211 are symmetrically distributed around the surface of the nozzle 210.

[0033] In this embodiment, the release agent spray gun 26 is fixed by setting a movable mounting base 25. The motor 23 drives the lead screw 24 to rotate, which causes the movable mounting base 25 to move left and right within the range of the slide rail 22. This enables the release agent spray gun 26 to perform automated spraying, avoiding the uneven spraying phenomenon caused by manually holding the release agent spray gun 26. By setting multiple sets of nozzles 211 on the surface of the nozzle 210, the nozzle 210 can spray the release agent in all directions, effectively improving the uniformity of the release agent spraying.
