Description

Technical Field

[0001] The utility model belongs to the field of casting moulds, in particular to an inlaid copper sleeve mould which is easy to demould. Background Art

[0002] Auto parts such as pump parts are produced by sand casting. Sand casting is the most widely used casting method in casting production. Sand is used as the main molding material. The sand is compacted to form a casting cavity. After the molten metal is poured and solidified, the sand mold is removed to take out the casting.

[0003] The traditional molding process is complicated and mostly done manually, that is, first place the base plate on the molding station, place the mold plate on the base plate, place the sand box outside the mold plate, inject the molding sand into the sand box and compact it, take out the mold plate, and because the mold plate has the shape of the molded part, the final sand box includes the corresponding mold cavity, and the pouring can be completed by injecting liquid metal into the mold cavity. However, for the final product of the bow-shaped casting, especially the casting with a through-hole bar head at the head end, there are problems such as difficult demoulding, poor product appearance quality, and easy sand inclusion, which requires a long sand throwing cycle, affecting production efficiency.

DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] Examples, such as Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides an inlaid copper sleeve mold that is easy to demould, including a first mold plate 1 and a second mold plate 2, both of which are provided with mounting holes 3, the first mold plate 1 is provided with two first bow-shaped parts 11 that are symmetrically distributed on the left and right, and the bow-shaped mouths of the two are arranged facing each other, the head end of the first bow-shaped part 11 is provided with a first hole mold 12, and the first hole mold 12 is provided with a first copper sleeve 13, and a gate process structure 14 connected to the two first bow-shaped parts 11 is provided between the two first bow-shaped parts 11, and the gate process structure 14 is T-shaped and is away from the first bow-shaped part 11. The first end of the mold plate 1 is provided with a first pouring cup 15, and the first mold plate 1 is provided with a plurality of plate-shaped exhaust channel convex shapes 16; the second mold plate 2 is provided with two second bow-shaped parts 21 that are symmetrically distributed on the left and right, and the bow-shaped mouths of the two are arranged facing each other, and the head end of the second bow-shaped part 21 is provided with a second hole mold 22, and the second hole mold 22 is provided with a second copper sleeve, and the second mold plate 2 is provided with a second pouring cup 24 on one side thereof, and the center line of the second pouring cup 24 is coaxial with the symmetry line of the two second bow-shaped parts 21; the side of the first mold plate 1 and the side of the second mold plate 2 can be detachably provided with a scraping strip 4. Among them, the first pouring cup 15, the pouring process structure 14 and the second pouring cup 24 can make the sand shell after the mold is closed have a reasonable pouring channel, especially to meet the pouring of the bow-shaped part.

[0019] Specifically, the first mold plate 1 and the second mold plate 2 can be installed in different sand boxes, and screws are installed in the installation holes 3 for installation and positioning, and the surface shapes of the first bow-shaped member 11 and the second bow-shaped member 21 constitute the inner mold surface of the sand shell. The final sand shell has the outer shape of the casting, and the device is particularly used for the sand shell used for the casting with a through-hole bar head. The first copper sleeve 13 and the second copper sleeve are inlaid, and the traditional direct casting process adopts the process of inlaying copper sleeves to separate the casting from the molding sand to a certain extent, ensure the quality of demoulding, and help control the production cost. Further, the device installs a scraping strip 4 on the side of the first mold plate 1 and the second mold plate 2. After the sand shell is formed, the scraping strip 4 is removed from the first mold plate 1 and the second mold plate 2, and the parting surface is swept in a horizontal sweeping manner to sweep away the excess residual sand from the parting surface to prevent the molding sand from affecting the subsequent pouring process, which is conducive to ensuring the quality of the casting.

[0020] In order to improve the quality of the casting, in addition to designing the exhaust channel convex shape 16 for generating the sand shell with the exhaust channel, the utility model also provides a filter convex shape 18 at the connection end between the first pouring cup 15 and the pouring process structure 14. In this way, before pouring, the filter is installed at the position where the filter convex shape 18 is formed, so that the poured metal liquid can be cleaned, thereby ensuring the purity of the liquid entering the cavity and improving the quality of the cast product.

[0021] In order to facilitate the disassembly and assembly of the scraping strip 4, the utility model is provided with a plurality of connection holes 41 distributed along the length direction of the scraping strip 4, and the first mold plate 1 and the second mold plate 2 are both provided with blind holes corresponding to the connection holes 41, and the connection holes 41 are connected to the blind holes by screws. At the same time, the edge of the scraping strip 4 is slightly higher than the thickness of the first mold plate 1 and the second mold plate 2, so that after the sand box is separated, the screws can be removed and the part of the scraping strip 4 that is higher than the mold plate can be held to scrape the molding sand.

[0022] In order to improve the molding quality and casting quality, the utility model is respectively provided with a pair of first anti-collision pins 17 and a second anti-collision pin 18 on the first mold plate 1 and the second mold plate 2. The anti-collision pin structure plays an anti-collision role during molding, and the pins are installed at the sand shell node position during casting to play a positioning role, thereby improving the quality of the sand shell and the quality of the final casting product.

[0023] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
