Description

Technical Field

[0001] This utility model relates to the field of wire drawing reel production technology, specifically a wire drawing reel production mold with an exhaust structure. Background Technology

[0002] Guy coils are key basic components used to fix power poles and towers in power, telecommunications, and municipal engineering fields. Their molding quality directly affects the stability and service life of the poles and towers. Guy coils are usually formed by casting with molds. If the air inside the mold cavity cannot be discharged in time during the molding process, it is easy to cause defects such as air holes, cracks, and material shortages on the product surface, reducing product strength and yield.

[0003] A search revealed a Chinese patent with publication number CN222874874U, which discloses a forming mold for a cable reel for a cement pole. The mold includes a housing, a slider fixedly connected to the inner wall of the housing, an adjusting component slidably connected to the outer surface of the slider, a groove at the bottom of the housing, a lifting component engaged inside the groove, and a graduated groove on the upper surface of the housing. The lifting component includes a housing A, a hydraulic cylinder fixedly installed inside the housing A, and a connecting rod fixedly connected to one end of the hydraulic cylinder.

[0004] However, in the existing technology, during the molding process, the material poured into the cavity will compress the air. The existing mold lacks an efficient venting channel, which makes it difficult for the air to be discharged quickly. This easily leads to defects such as air holes and looseness inside the finished product, which seriously affects the structural strength and load-bearing capacity of the wire drawing disc. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the shortcomings and defects of existing technologies, such as the difficulty in quickly expelling air, which easily leads to defects like air holes and looseness inside the finished product, severely affecting the structural strength and load-bearing capacity of the wire drawing reel.

[0006] The present invention discloses a production mold for a wire reel with a venting structure, comprising a shell, a cover plate at the upper end of the shell, a fixing component between the cover plate and the shell, at least two venting grooves along the axis on the inner wall of the shell, and a plurality of venting grooves evenly distributed along the axis, a vent hole on one side of each venting groove, the vent hole penetrating the shell, one end of the vent hole communicating with the venting groove, and a baffle plate inside the shell, the baffle plate being inserted into the venting groove.

[0007] Furthermore, the exhaust channel is configured as a "U" shape, and the baffle has the same shape as the exhaust channel.

[0008] Furthermore, the baffle is provided with weight-reduction holes, and there are multiple weight-reduction holes evenly distributed on the baffle.

[0009] Furthermore, the fixing component includes a first connecting block and a second connecting block. The first connecting block is fixedly installed on the upper end of the outer shell and has a sliding groove. The second connecting block is fixedly installed on the upper end of the cover plate and has a fixing bolt fixedly installed on the second connecting block. The fixing bolt passes through the sliding groove and has a fixing cap. The fixing cap is threadedly connected to the fixing bolt.

[0010] Furthermore, the cover plate and the outer shell are symmetrically arranged on both sides, and at least two connecting blocks one or two are provided on the same side of the cover plate and the outer shell, with multiple connecting blocks one and connecting blocks two evenly distributed.

[0011] Furthermore, the fixing bolt is slidably disposed with the sliding groove, and the outer ring of the cover plate is slidably disposed with the inner wall of the outer shell and the venting groove.

[0012] Furthermore, a feed inlet and an iron ring inlet are installed on the upper end of the cover plate, the iron ring inlet is located in the middle of the cover plate, handles are fixedly installed at both ends of the cover plate, and support frames are fixedly installed at both ends of the lower part of the outer shell, with fixing holes provided on the support frames.

[0013] Furthermore, a dustproof net is detachably installed at the end of the vent that is away from the exhaust groove. The dustproof net is fixed to the outer wall of the outer shell by a buckle, and the outer wall of the baffle is tightly fitted to the inner wall of the exhaust groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model constructs an efficient exhaust path by uniformly setting at least two "U"-shaped exhaust grooves along the axis on the inner wall of the outer shell, and combining them with vent holes that penetrate the outer shell and communicate with the exhaust grooves. At the same time, the baffle that fits tightly and is highly compatible with the exhaust grooves not only prevents leakage of casting materials, but also reduces defects such as air holes, cracks, and material shortages on the surface and inside of the pull wire reel, improves the structural strength and load-bearing capacity of the product, ensures the stability of the pull wire reel in power, communication and other engineering projects, and improves the finished product qualification rate.

[0015] 2. The plug-in connection between the baffle and the venting groove of this utility model ensures uniform force distribution during mold operation and allows for flexible adjustment of the cover plate height to adapt to different casting requirements. With the symmetrically distributed connecting block one, connecting block two, and sliding fixing bolts and groove structures, the position of the cover plate and the outer shell can be fixed. The multiple evenly distributed weight-reducing holes on the baffle plate reduce the overall weight of the mold, making it easy to handle and operate. The detachable dustproof net at the end of the venting hole can prevent impurities from entering and clogging the venting channel, thus extending the service life of the mold.

[0019] Please see Figure 1 , Figure 4 The present invention relates to a production mold for a wire reel with an exhaust structure, comprising a housing 1, a cover plate 2 at the upper end of the housing 1, a sealing groove on the outer ring of the cover plate 2, and a high-temperature resistant silicone gasket embedded in the sealing groove to prevent leakage of casting material. A feed inlet 5 and an iron ring inlet 6 are installed at the upper end of the cover plate 2, the iron ring inlet 6 being located in the middle of the cover plate 2. Handles 16 are fixedly installed at both ends of the cover plate 2, the handles 16 being U-shaped stainless steel structures. Support frames 12 are fixedly installed at both ends of the lower part of the housing 1.

[0020] See Figure 1 , Figure 2 , Figure 4As shown, the support frame 12 is provided with fixing holes 13. By cooperating with bolts, the outer shell 1 can be installed in a preset position. A fixing component is provided between the cover plate 2 and the outer shell 1. The fixing component includes a connecting block 7 and a connecting block 8. The connecting block 7 is fixedly installed on the upper end of the outer shell 1 and is provided with a sliding groove 11. The connecting block 8 is fixedly installed on the upper end of the cover plate 2 and is fixedly installed with a fixing bolt 9. The fixing bolt 9 passes through the sliding groove 11.

[0021] See Figure 2 As shown, a fixing cap 10 is provided on the fixing bolt 9. The fixing bolt 9 and the fixing cap 10 are made of 304 stainless steel. The fixing cap 10 is threaded to the fixing bolt 9. The two sides of the cover plate 2 and the outer shell 1 are symmetrically arranged. At least two connecting blocks 1 7 or connecting blocks 2 8 are provided on the same side of the cover plate 2 and the outer shell 1. The multiple connecting blocks 1 7 and connecting blocks 2 8 are evenly distributed, so that the cover plate 2 and the outer shell 1 are subjected to uniform force, thereby improving the stability of the connection.

[0022] See Figure 1 , Figure 2 , Figure 3 As shown, the fixing bolt 9 and the sliding groove 11 are slidably connected. The fixing bolt 9 and the sliding groove 11 cooperate to position the cover plate 2, so as to facilitate the sliding connection of the cover plate 2 and the inner wall of the outer shell 1. The outer ring of the cover plate 2 is slidably connected to the inner wall of the outer shell 1 and the exhaust groove 3. At least two exhaust grooves 3 are provided along the axis of the inner wall of the outer shell 1. The multiple exhaust grooves 3 are evenly distributed along the axis. A vent hole 4 is provided on one side of the exhaust groove 3. The vent hole 4 penetrates the outer shell 1 and one end of the vent hole 4 is connected to the exhaust groove 3.

[0023] See Figure 3 , Figure 5 As shown, a dustproof net is detachably installed at the end of the vent 4 away from the exhaust groove 3. The dustproof net is fixed to the outer wall of the outer shell 1 by a buckle. The outer wall of the baffle 14 is tightly fitted to the inner wall of the exhaust groove 3. The baffle 14 is provided inside the outer shell 1. The outer shell 1, cover plate 2, and baffle 14 are made of high-strength aluminum alloy. The inner wall is sprayed with a PTFE anti-stick coating to reduce the adhesion of the casting material and facilitate demolding.

[0024] See Figure 2 , Figure 5 As shown, the baffle 14 is provided with weight reduction holes 15. There are multiple weight reduction holes 15, which are evenly distributed on the baffle 14. The baffle 14 is inserted into the exhaust groove 3. The exhaust groove 3 is set in a "U" shape. The shape of the baffle 14 is the same as that of the exhaust groove 3.

[0025] The implementation principle is as follows: Select a baffle 14 of the corresponding height according to the height requirement of the wire drawing disc. Insert the baffle 14 into the corresponding exhaust groove 3 according to the length requirement of the wire drawing disc to ensure that the outer wall of the baffle 14 is tightly fitted with the inner wall of the exhaust groove 3. Then, align the fixing bolt 9 at the upper end of the cover plate 2 with the slide groove 11 and drive the cover plate 2 to move towards the outer shell 1. At the same time, the fixing bolt 9 moves in the slide groove 11 to restrict and position the cover plate 2. As the cover plate 2 moves down, the outer ring slides and fits against the inner wall of the outer shell 1 and the exhaust groove 3 until the cover plate 2 contacts the top of the baffle 14. Then tighten the fixing cap 10 on the fixing bolt 9 to fix the relative position of the cover plate 2 and the outer shell 1. The casting material is injected into the shell 1 through the feed port 5, and the iron ring is placed in the corresponding preset position in the middle of the cover plate 2 through the iron ring port 6 to ensure the compatibility between the iron ring and the casting material. When the casting material fills the shell 1, it squeezes the air inside the cavity. The air quickly gathers along the exhaust groove (3) on the inner wall of the shell 1 and is discharged outside the mold through the vent hole 4 connected to the exhaust groove 3. The detachable dustproof net at the end of the vent hole 4 prevents external impurities from entering and blocking the exhaust channel.

[0026] After the pull coil is formed, loosen the fixing cap 10, remove the cover plate 2 through the handles 16 at both ends of the cover plate 2, and take out the formed pull coil; remove the dustproof net at the end of the vent hole 4 for cleaning.

[0027] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
