[0040] Please refer to Figures 1 to 4The utility model provides a taper sleeve casting forming tool, which comprises a lower sand mold 1, a taper sleeve mold 2, a sand core 3 and an upper sand mold 4. The taper sleeve mold 2 is a foam component and is arranged on the upper surface of the lower sand mold 1. The sand core 3 is filled in the inner cavity of the taper sleeve mold 2, and the outer periphery of the sand core 3 is in conformal contact with the inner wall of the taper sleeve mold 2. The bottom of the sand core 3 is connected with the lower sand mold 1. The upper sand mold 4 is buckled on the outer wall of the taper sleeve mold 2 and the upper surface of the lower sand mold 1. The inner wall of the upper sand mold 4 is in conformal contact with the outer wall of the taper sleeve mold 2.
[0041] It should be noted that the lower sand mold 1 and the sand core 3 are connected as a whole in the embodiment, so that the sand core 3 and the lower sand mold 1 are kept relatively fixed.
[0042] In the specific implementation, the upper sand mold 4 is covered on the lower sand mold 1, and the inner wall of the upper sand mold 4 is in contact with the taper sleeve mold 2. When the upper sand mold 4 is formed, the taper sleeve mold 2 is removed. The space enclosed by the upper sand mold 4, the sand core 3 and the lower sand mold 1 is in the shape of a taper sleeve casting. Therefore, only liquid metal needs to be poured between the upper sand mold 4 and the lower sand mold 1.
[0043] It should be noted that the lower sand mold 1, the sand core 3 and the upper sand mold 4 are all formed by molding sand and adhesive.
[0044] Compared with the prior art, the taper sleeve mold 2 of the taper sleeve casting forming tool provided in the embodiment is replaced by a foam mold. The cost of the foam mold is much lower than that of a wooden mold, so that the consumption cost can be reduced. The foam mold is easy to process, and can be processed by a hot cutting device or manually. The processing period is short, which is much shorter than that of polishing a wooden block. Therefore, the preparation period before pouring can be shortened, and the production efficiency of the casting can be improved.
[0045] In some embodiments, referring to Figure 3 The taper sleeve mold 2 has a first cavity 21 and a second cavity 22 arranged in sequence from top to bottom inside the taper sleeve mold 2. The first cavity 21 is in communication with the second cavity 22. The first cavity 21 is filled with parting sand. The top of the parting sand is in contact with the upper sand mold 4. The second cavity 22 is filled with the sand core 3.
[0046] In the embodiment, the second cavity 22 and the first cavity 21 are in communication, and the first cavity 21 is in communication with the outside. Before the sand core 3 is formed, the sand is poured from the first cavity 21 into the second cavity 22 and fills the second cavity 22. The filling method is simple and ensures the forming quality of the sand core 3. The parting sand is arranged in the first cavity 21, which can fill the first cavity 21 and isolate the sand core 3 and the upper sand mold 4. After the upper sand mold 4 is formed, the upper sand mold 4 and the sand core 3 are separated, which facilitates the separation of the upper sand mold 4, the lower sand mold 1 and the sand core 3.
[0047] In the implementation, the parting sand does not adhere to the sand core 3 or the upper sand mold 4, so that a gap is formed between the top surface of the sand core 3 and the upper sand mold 4, and the space enclosed by the upper sand mold 4, the sand core 3 and the lower sand mold 1 after the upper sand mold 4 is formed has the same shape as the taper sleeve casting, thereby ensuring the casting quality.
[0048] In some embodiments, referring to Figure 3 , the top surface of the first cavity 21 is flush with the top surface of the taper sleeve mold 2. In order to improve the molding quality, after the first cavity 21 is filled with the parting sand, the upper surface of the parting sand is flush with the top surface of the taper sleeve mold 2, and the inner wall of the upper sand mold is a flat horizontal surface after the upper sand mold 4 is formed, thereby ensuring the casting and molding quality of the casting.
[0049] In some embodiments, referring to Figure 3 , the first cavity 21 and the second cavity 22 are annular cavities, and the outer diameter of the bottom of the first cavity 21 is smaller than the outer diameter of the top of the second cavity 22. The first cavity 21 is used to fill the parting sand to isolate the sand core 3 and the upper sand mold 4, and the outer diameter of the bottom of the first cavity 21 is set to be smaller than the outer diameter of the top of the second cavity 22, which can meet the requirement of pouring the sand into the sand core 3, reduce the amount of parting sand used in the first cavity, reduce the cost, and improve the economic benefit.
[0050] In some embodiments, referring to Figure 4 , the taper sleeve mold 2 includes a mold body 23 and a movable block 24. The mold body 23 is a cylindrical member, the outer diameter of the mold body 23 gradually increases from top to bottom, the outer peripheral side wall of the mold body 23 is provided with an installation channel penetrating through the upper and lower portions, the installation channel is adapted to be inserted into the movable block 24, and the mold body 23 and the movable block 24 cooperatively form the first cavity 21 and the second cavity 22. The mold body 23 and the movable block 24 are designed in a split type. In use, the mold body 23 is placed on the lower sand mold 1, and the movable block 24 is used to block the mold body 23 to form the first cavity 21 and the second cavity 22, so that the sand required for molding the sand core 3 can be poured. When the upper sand mold 4 is formed and demolded, the movable block 24 is first removed from the installation channel, and then the mold body 23 is removed. In the whole process, the taper sleeve mold 2 is removed in two steps. Compared with the existing integral removal, the difficulty of removing the movable block 24 on one side of the sand core 3 is low. After the movable block 24 is removed, the mold body 23 can be slightly deformed from the installation channel, so that the inner wall of the mold body 23 is separated from the sand core 3, the difficulty of disassembly is reduced, the mold body 23 and the movable block 24 are not easily damaged in the disassembly process, the probability of damage of the taper sleeve mold 2 is reduced, the taper sleeve mold 2 can be repeatedly used, the number of taper sleeve molds 2 used is reduced, and the cost is saved.
[0051] In some embodiments, referring to Figure 1 and Figure 2The outer periphery of the taper sleeve mold 2 is sleeved with an anti-expansion ring 5. The anti-expansion ring 5 is sleeved on the outer periphery of the mold body 23 and the movable block 24, and prevents the movable block 24 from separating outward from the mold body 23 when filling the sand core 3, so as to ensure that the sizes of the second cavity 22 and the first cavity 21 do not change, and further ensure the processing quality of the sand core 3, so that the formed sand core 3 is a standard part, and meets the casting standard.
[0052] It should be noted that the anti-expansion ring 5 is removed after the sand core 3 is formed.
[0053] In some embodiments, referring to Figure 2 The outer diameter of the taper sleeve mold 2 gradually increases from top to bottom, the anti-expansion ring 5 is provided with a plurality of anti-expansion rings 5, the plurality of anti-expansion rings 5 are arranged in the up-down direction, and the inner diameters of the plurality of anti-expansion rings 5 sequentially increase from top to bottom. The plurality of anti-expansion rings 5 can be sequentially arranged on the outer periphery of the taper sleeve mold 2 from top to bottom, so as to reduce the pressure borne by a single anti-expansion ring 5, the resistance borne by a single anti-expansion ring 5 is small, and the taper sleeve mold 2 will not be damaged. The plurality of anti-expansion rings 5 can be arranged at multiple positions on the installation channel to prevent expansion, so as to ensure that the taper sleeve mold 2 will not be partially expanded, and the forming quality of the sand core 3 is ensured.
[0054] In some embodiments, referring to Figure 2 The inner wall of the anti-expansion ring 5 is in close contact with the outer periphery of the taper sleeve mold 2. The close contact between the inner wall of the anti-expansion ring 5 and the outer periphery of the taper sleeve mold 2 can increase the contact area of the anti-expansion ring 5 and the taper sleeve mold 2, reduce the resistance borne by the anti-expansion ring 5, and be beneficial to protecting the taper sleeve mold 2, so that the taper sleeve mold 2 can be repeatedly used.
[0055] In some embodiments, the taper sleeve mold 2 and the parting sand cooperate to form the pouring shape of the taper sleeve casting. The shapes are the same, and when the taper sleeve mold 2 is removed, the space enclosed by the upper sand mold 4, the sand core 3 and the lower sand mold 1 is the shape of the taper sleeve casting, so that the liquid metal can be directly poured, and the pouring difficulty is reduced.
[0056] In some embodiments, referring to Figure 1 The taper sleeve casting forming tool further comprises a casting box 6, and the upper sand mold 4 and the lower sand mold 1 are arranged in the casting box 6. The casting box 6 can limit the lower sand mold 1 and the upper sand mold 4 in the horizontal direction, and the sand of the upper sand mold 4 can be stacked in the casting box 6, so that the upper sand mold 4 is formed, and the use cost of the upper sand mold 4 is reduced.
[0057] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
