Description

Technical fields:

[0001] This utility model relates to the field of wheel hub related technology, and more specifically to a slanted positioning wheel hub mold structure. Background technology:

[0002] Based on the existing wheel hub mold structure principle, the lower mold is mainly a fixed mold, and the upper mold is a moving mold, which can be moved up and down by hydraulic cylinders. In addition, there are 4 side molds, each of which is moved in and out by a hydraulic cylinder; thus realizing the opening and closing process of the wheel hub mold.

[0003] Each of its side molds requires a separate hydraulic cylinder to drive it, which is complex in structure and expensive. Moreover, the pushing distance and running time of the push rod of each hydraulic cylinder need to be kept as consistent as possible, making the initial installation and adjustment quite troublesome.

[0004] Therefore, a wheel hub mold device without side mold cylinders, as disclosed in Chinese Patent Publication No. CN222470648U, includes an upper mold connecting plate and a bottom mold plate. The upper mold connecting plate is located directly above the bottom mold plate. A bottom mold is fixed in the center of the top surface of the bottom mold plate. An upper mold plate is installed below the upper mold connecting plate. Side mold guide seats are fixed on the front and rear bottom surfaces of both sides of the upper mold plate. A movable through groove is formed between two adjacent side mold guide seats. The corresponding side mold is located between the corresponding two adjacent side mold guide seats and moves laterally along the movable through groove. At least one guide rod extending obliquely outward and upward is fixed on the bottom mold plate directly below the side mold. The guide rod is inserted into an oblique through hole formed on the corresponding side mold. Its side molds do not require hydraulic cylinder pushing; they only need to descend the upper mold plate to bring the upper mold and four side molds together and close with the bottom mold to complete the mold closing.

[0005] However, the side mold moves only by being guided by the side guide strips on the side wall, and there is still a small distance or gap between the side mold and the side mold guide seat. This means that when the side mold moves between the two side mold guide seats without the obliquely extending guide rod inserted, there will still be a small deviation, which may cause jamming when the guide rod is inserted later, affecting the mold closing effect.

[0006] At the same time, the heat dissipation effect of the existing side mold is generally poor and cannot meet the heat dissipation requirements during casting cooling. Utility Model Content:

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a slanted positioning wheel hub mold structure. The upper protruding positioning strip formed on the top surface of the side mold is inserted into the corresponding position of the top guide groove formed on the bottom surface of the upper mold plate, which ensures that the position of the side mold is more accurate when it moves and basically does not deviate. This ensures that it can be accurately inserted into the slanted guide rod later. At the same time, it has a heat dissipation structure so that the triangular prism block has a heat dissipation function, thereby reducing the temperature of the side mold and ensuring the casting effect.

[0008] The solution of this utility model to the aforementioned technical problem is:

[0009] A slanted positioning wheel hub mold structure includes an upper mold plate and a bottom mold plate. A side mold locking ring is fixed to the top edge of the bottom mold plate. The inner wall of the upper to middle part of the side mold locking ring is a conical wall with a larger inner diameter at the top and a smaller inner diameter at the bottom. Multiple outwardly extending slanted guide rods are fixed to the left, right, front and rear parts of the top surface of the bottom mold plate.

[0010] The upper template has triangular prism blocks fixed at the front and rear left and right ends of the bottom surface. A transverse guide groove is formed in the middle of the opposite wall of two adjacent triangular prism blocks. The corresponding side mold is inserted between the corresponding two adjacent triangular prism blocks. A transverse convex part is provided in the middle of the left and right side walls of the side mold. The transverse convex part is inserted into the corresponding transverse guide groove and cooperates with it. An upper protruding positioning strip extending from the outside to the inside is formed in the middle of the top surface of the side mold. The upper protruding positioning strip is inserted into the top guide groove formed in the bottom surface of the upper template at the corresponding position and cooperates with it.

[0011] The lower part of the four side molds is inserted into the side mold locking ring. The outer wall of the middle part of the side mold is a conical wall, which presses against the conical wall of the side mold locking ring. The oblique guide rod is inserted into the oblique through hole formed in the middle of the corresponding side mold.

[0012] The upper template has an upper through hole formed on its edge that communicates with and corresponds to the oblique through hole of the side mold, and the top of the oblique guide rod is inserted into the corresponding upper through hole.

[0013] The outer ends of the two transverse guide slots formed in the middle of the two vertical walls of the triangular prism block extend out of the corresponding vertical walls, and the other end extends out of the corresponding vertical walls and is connected to them.

[0014] The top surface of the side mold locking ring is formed with multiple vertically downward extending slots. The lower part of the corresponding triangular prism block is inserted into the corresponding slot, which cooperates with the slot. Its bottom surface presses against the bottom surface of the slot, and its side wall is in close contact with the inner side wall of the corresponding slot.

[0015] The bottom template, located directly below the side mold locking ring, has a ventilation and heat dissipation groove extending from the outside to the inside on its top edge. The outer end of the ventilation and heat dissipation groove extends out of the outer wall of the bottom template.

[0016] The outer side wall of the side mold has an inwardly extending heat dissipation groove formed in the middle, and a vertical reinforcing part is formed in the middle of the outer end of the heat dissipation groove. The top and bottom ends of the vertical reinforcing part are formed on the top and bottom surfaces of the heat dissipation groove.

[0017] The heat dissipation groove has two oblique guide tubes formed in it. The top and bottom ends of the oblique guide tubes are formed on the top and bottom surfaces of the heat dissipation groove. The middle through hole of the oblique guide tube is the middle part of the oblique through hole. The upper part of the oblique through hole is formed in the middle of the upper part of the side mold, and the lower part of the oblique through hole is formed in the middle of the lower part of the side mold. The upper and bottom ends of the oblique through hole extend out of the top and bottom surfaces of the side mold.

[0018] An annular groove is formed on the bottom inner wall of the side mold. The outer edge of the lower mold core is inserted into the annular groove, and its top surface presses against the top surface of the annular groove. The outer wall of the lower mold core is in close contact with the inner wall of the annular groove.

[0019] The bottom surface of the side mold locking ring is formed with multiple positioning parts, which are inserted into the corresponding positioning recesses formed on the top edge of the bottom mold plate and cooperate with them.

[0020] The triangular prism block has an upwardly extending vertical hole formed on the outer side of the middle of its bottom surface, and an inwardly extending radial hole formed on the middle of the lower outer wall of the triangular prism block. The radial hole and the vertical hole are connected. A vertical air passage is formed in the middle of the inner end of the triangular prism block. The two ends of the vertical air passage extend out of the upper and lower end faces of the triangular prism block. The radial hole communicates with the corresponding vertical air passage. The top of the vertical air passage communicates with and is aligned with the air outlet hole formed on the upper template.

[0021] The outstanding effect of this utility model is:

[0022] Its side mold has a raised positioning strip on the top surface that fits into the corresponding top guide groove on the bottom surface of the upper mold plate. This ensures that the side mold moves more accurately and will not deviate. It also ensures that it can be accurately inserted into the oblique guide rod later. At the same time, it has a heat dissipation structure so that the triangular prism block has a heat dissipation function, thereby reducing the temperature of the side mold and ensuring the casting effect.

[0030] Figure 8 This is a partial structural diagram of the bottom template. Detailed implementation method:

[0031] For example, see below. Figures 1 to 8 As shown, a slanted positioning wheel hub mold structure includes an upper template 10 and a bottom template 20. A side mold locking ring 30 is fixed to the top edge of the bottom template 20. The inner wall of the upper to middle part of the side mold locking ring 30 is a conical wall with a larger inner diameter at the top and a smaller inner diameter at the bottom. Multiple positioning parts are formed in the middle of the bottom surface of the side mold locking ring 30. The positioning parts are inserted into and cooperate with the corresponding positioning recesses 13 formed in the top edge of the bottom template 20. This structure improves the accuracy of the fixed position of the side mold locking ring 30.

[0032] Multiple outwardly extending oblique guide rods 21 are fixed on the left, right, front and rear parts of the top surface of the bottom template 20. The oblique guide rods 21 are located inside the side mold locking ring 30. In this embodiment, a total of 8 oblique guide rods 21 are provided, two each on the left, right, front and rear parts.

[0033] Furthermore, the front and rear left and right ends of the bottom surface of the upper template 10 are fixed with triangular prism blocks 40. The middle of the opposite wall of two adjacent triangular prism blocks 40 is formed with a transverse guide groove 41. The corresponding side mold 50 is inserted between the corresponding two adjacent triangular prism blocks 40. The middle of the left and right side walls of the side mold 50 is provided with a side transverse protrusion 51 (in this embodiment, the side transverse protrusion 51 is directly formed, or the side transverse protrusion 51 can be fixed by bolts). The side transverse protrusion 51 is inserted into the corresponding transverse guide groove 41 and cooperates with it. The middle of the top surface of the side mold 50 is formed with an upper protrusion positioning strip 55 extending from the outside to the inside. The upper protrusion positioning strip 55 is inserted into the top guide groove 45 extending from the outside to the inside formed on the bottom surface of the upper template 10 at the corresponding position. The upper protrusion positioning strip 55 is inserted into the top guide groove 45 and cooperates with it.

[0034] The left and right side walls at the inner end of the side mold 50 are inclined walls. Among the four side molds 50, the corresponding inclined walls of every two adjacent side molds 50 are in close contact.

[0035] The lower parts of the four side molds 50 are inserted into the side mold locking rings 30. The outer wall of the middle part of the side mold 50 is a conical wall, which presses against the conical wall of the side mold locking rings 30. The oblique guide rods 21 are inserted into the oblique through holes 56 formed in the middle of the corresponding side molds 50.

[0036] The top guide groove 45, which extends inward from the outer end, is formed on the bottom surface of the upper template 10 by inserting the upper protruding positioning strip 55 into the corresponding position. This allows the upper part of the side mold 50 to have a guiding function when it moves, ensuring that the side mold 50 moves along the upper protruding positioning strip 55. This makes the position of the side mold 50 more accurate and basically does not deviate, ensuring that it can be accurately inserted into the oblique guide rod 21 later.

[0037] Furthermore, the upper template 10 has an upper through hole 11 formed on its edge, which communicates with and corresponds to the oblique through hole 56 of the side mold 50, and the top of the oblique guide rod 21 is inserted into the corresponding upper through hole 11.

[0038] Furthermore, the triangular prism block 40 is perpendicular to the bottom surface of the upper template 10, and the opposite walls of each pair of adjacent triangular prism blocks 40 are parallel. The left and right side walls of the corresponding side mold 50 are in close contact with or near the opposite walls of the corresponding two triangular prism blocks 40, which ensures that the side mold 50 can move along the opposite walls of the two triangular prism blocks 40. At the same time, it ensures the tightness with the side walls, without too large a gap or with almost no gap.

[0039] Furthermore, the outer ends of the two transverse guide grooves 41 formed in the middle of the two vertical walls of the triangular prism block 40 extend out of the corresponding vertical walls, and the other ends extend out of the corresponding vertical walls and are connected.

[0040] Furthermore, the top surface of the side mold locking ring 30 is formed with a plurality of vertically downward extending slots 31, and the lower part of the corresponding triangular prism block 40 is inserted into the corresponding slot 31, which cooperates with the slot 31, with its bottom surface pressing against the bottom surface of the slot 31 and its side wall tightly abutting the inner side wall of the corresponding slot 31.

[0041] Furthermore, an upper mold core 60 is fixed in the middle of the bottom surface of the upper template 10, and a lower mold core 70 is fixed in the middle of the top surface of the bottom template 20. The upper mold core 60, the lower mold core 70, and the four side molds 50 form a molding cavity.

[0042] Furthermore, the bottom template 20, located directly below the side mold 50 and below the side mold locking ring 30, has a ventilation and heat dissipation groove 22 extending from the outside to the inside on its top edge. The outer end of the ventilation and heat dissipation groove 22 extends out of the outer side wall of the bottom template 20. This structure reduces the contact area between the bottom surface of the side mold locking ring 30 and the top surface of the bottom template 20, increasing the space for heat dissipation.

[0043] Furthermore, an inwardly extending heat dissipation groove 52 is formed in the middle of the outer side wall of the side mold 50, and a vertical reinforcing part 53 is formed in the middle of the outer end of the heat dissipation groove 52. The top and bottom ends of the vertical reinforcing part 53 are formed on the top and bottom surfaces of the heat dissipation groove 52.

[0044] Two oblique guide tubes 54 are formed in the heat dissipation groove 52. The top and bottom ends of the oblique guide tubes 54 are formed on the top and bottom surfaces of the heat dissipation groove 52. The middle through hole of the oblique guide tubes 54 is the middle part of the oblique through hole 56. The upper part of the oblique through hole 56 is formed in the middle of the upper part of the side mold 50, and the lower part of the oblique through hole 56 is formed in the middle of the lower part of the side mold 50. The upper and bottom ends of the oblique through hole 56 extend out of the top and bottom surfaces of the side mold 50.

[0045] The above structure not only reduces the weight of the side mold 50, but also improves the heat dissipation effect by connecting the heat dissipation groove 52 to the outside.

[0046] An annular groove is formed on the bottom inner wall of the side mold 50. The outer edge of the lower mold core 70 is inserted into the annular groove, and its top surface presses against the top surface of the annular groove. The outer wall of the lower mold core 70 is in close contact with the inner wall of the annular groove.

[0047] Furthermore, the triangular prism block 40 has an upwardly extending vertical hole 42 formed on the outer side of the middle part of the bottom surface. The corresponding slot 31 can fix a positioning post (not shown in the figure) in the middle of the bottom surface. It can be inserted into the vertical hole 42 and cooperate with it. The upper part of the positioning post is inserted into the lower part of the vertical hole 42.

[0048] The lower outer side wall of the triangular prism block 40 has an inwardly extending radial hole 43 formed in the middle. The radial hole 43 is connected to the middle of the vertical hole 42. The middle of the inner end of the triangular prism block 40 has a vertical air passage hole 44 formed in the middle. The two ends of the vertical air passage hole 44 extend out of the upper and lower end faces of the triangular prism block 40. The radial hole 43 is connected to the corresponding vertical air passage hole 44. The top of the vertical air passage hole 44 is connected to and aligned with the air outlet hole 15 formed on the upper template 10.

[0049] The above structure allows the air pipe to be connected to the outer end of the radial hole 43. During casting, when cooling is required, air can be introduced. The gas enters from the radial hole 43 into the vertical air guide hole 44 and is then blown out from the end of the vertical air guide hole 44. After entering, the gas exchanges heat with the triangular prism block 40 and is then blown out, thus achieving heat dissipation for the triangular prism block 40. The triangular prism block 40 is in contact with the side mold 50 and is in heat exchange with the side mold 50, thereby indirectly dissipating heat from the side mold 50, meeting the casting heat dissipation requirements, and improving the casting effect.

[0050] In use, the principle of this embodiment is basically the same as that of the wheel hub mold device without side mold cylinder authorized in CN222470648U, which will not be described in detail here.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
