TECHNICAL FIELD

[0001] The utility model relates to die casting technical field especially relates to a die casting mould for filter bottle connecting piece formed by die casting. BACKGROUND

[0002] In the production and processing such as Figure 1 When the filter bottle connecting piece shown in the figure is produced and processed, two pipe holes 012 that are coaxial with the center axis and are perpendicular to the communication hole 011 are formed on the middle connecting ball 01 by using a cutter. However, since the surface to be processed is a spherical surface, the advancing route of the cutter is easy to be inclined when the two pipe holes 012 are formed by using the cutter, which results in that the center axes of the two pipe holes 012 are not coaxial, and further results in that the filter bottle connecting piece produced and processed is unqualified, and even cannot be used. SUMMARY

[0003] In order to improve the production and processing qualification rate of the filter bottle connecting piece, the utility model provides a die casting mould for filter bottle connecting piece, which comprises a mould core, a mould cavity formed by the dynamic cavity and the fixed cavity is arranged in the mould core, the dynamic cavity is arranged on the dynamic mould core, two positioning end faces are arranged in the spherical groove in the dynamic cavity, the positioning end faces correspond to the positions of the pipe holes on the middle connecting ball of the filter bottle connecting piece, and the positioning end faces are parallel to the radial section of the pipe holes. When the die casting mould for filter bottle connecting piece is used to form the filter bottle connecting piece blank by die casting, the positioning surface that is matched with the positioning end face is formed on the position of the pipe hole on the middle connecting ball of the filter bottle connecting piece blank formed by die casting. In this way, when the pipe hole is formed on the middle connecting ball of the filter bottle connecting piece blank formed by die casting, the production and processing personnel can directly position and form the pipe hole on the positioning surface by using the cutter. Since the positioning surface is a plane matched with the positioning end face, that is, the positioning surface is a plane parallel to the radial section of the pipe hole, the positioning is simple and convenient when the pipe hole is processed, and the cutter is not easy to be inclined in the advancing process, so that the center axes of the two pipe holes formed on the middle connecting ball of the filter bottle connecting piece are coaxial, and the production and processing qualification rate of the filter bottle connecting piece is improved.

[0004] Preferably, the positioning end surface is a circular surface, the central axis of the positioning end surface coincides with the central axis of the tube hole, and the radius of the positioning end surface is equal to the radius of the tube hole. Thus, because the positioning end surface is a circular surface, the positioning surface die-cast on the filter bottle connector blank that mates with the positioning end surface is also a circular surface, facilitating tool positioning during subsequent processing and improving processing efficiency. Furthermore, the connecting surface between the positioning end surface and the inner wall of the spherical groove is an arcuate surface, and the positioning end surface and the connecting surface are connected to form a cylindrical positioning structure. Thus, a curved positioning surface is formed on the spherical surface of the die-cast central connecting ball of the filter bottle connector blank, mates with the curved connecting surface of the positioning structure. During subsequent tube hole processing, the tool holder for the tool used to process the tube hole can be directly attached to the curved positioning surface, locating the tool tip at the center of the positioning surface. This simplifies and facilitates positioning, effectively improving subsequent processing efficiency, and thereby reducing the production and processing costs of the filter bottle connector. Further preferably, an arcuate groove is provided on the inner wall of the spherical groove, and the arcuate groove is located in the extending direction of the positioning structure at one end of the positioning end surface. Thus, a cylindrical positioning post with the positioning surface as a radial end surface is formed on the central connecting ball of the filter bottle connector blank die-cast using the die-casting mold of the filter bottle connector of the present invention. During subsequent processing of the tube hole, the production and processing personnel only need to determine the inner diameter of the tube hole based on the arcuate side surface of the positioning post. This simplifies and facilitates the processing, effectively improving subsequent processing efficiency and thereby reducing the production and processing costs of the filter bottle connector.

In the die casting die of the filter bottle connecting piece of the utility model, the filter bottle connecting piece is formed by die casting as Figure 6The filter bottle connector blank 2 is shown, and the position where the hole is formed on the middle connecting ball 21 of the filter bottle connector blank 2 formed by die casting is formed with a positioning face 211 which is matched with the positioning end face 1111. In this way, when the hole is formed on the middle connecting ball 21 of the filter bottle connector blank 2 formed by die casting, the production and processing personnel can directly position the hole on the positioning face 211 by using a tool. Since the positioning face 211 is a plane which is matched with the positioning end face 1111, that is, the positioning face 211 is a plane which is parallel to the radial section of the hole, the positioning is simple and convenient when the hole is processed, and the tool is not easy to tilt during the advancement, so that the center axes of the two holes formed on the middle connecting ball of the filter bottle connector are collinear, and the production and processing qualification rate of the filter bottle connector is improved. Preferably, the positioning end face 1111 is a circular face, the center axis of the positioning end face 1111 coincides with the center axis of the hole, and the radius of the positioning end face 1111 is equal to the radius of the hole. In this way, since the positioning end face 1111 is a circular face, the positioning face 211 which is matched with the positioning end face 1111 formed on the filter bottle connector blank 2 by die casting is also a circular face, which facilitates the positioning of the tool during subsequent processing and improves the processing efficiency. Preferably, the connecting face 1112 between the positioning end face 1111 and the inner wall of the spherical groove is an arc face, and the positioning end face 1111 and the connecting face 1112 form a cylindrical positioning structure (not shown in the figure). In this way, the arc-shaped connecting face 212 which is matched with the arc-shaped connecting face 1112 of the positioning structure is formed on the spherical surface of the middle connecting ball 21 of the filter bottle connector blank 2 formed by die casting. When the hole is processed subsequently, the tool holder of the tool used for processing the hole directly matches the arc-shaped connecting face 212, so that the tool tip is located at the center position of the positioning face 211, the positioning is simple and convenient, the subsequent processing efficiency can be effectively improved, and the production and processing cost of the filter bottle connector can be reduced. Preferably, the inner wall of the spherical groove is provided with an arc-shaped groove 1113 which is located in the extension direction of the positioning structure at one end of the positioning end face 1111. That is, the inner wall of the spherical groove is provided with two arc-shaped grooves 1113 which are located between the two cylindrical positioning structures formed by the connecting of the positioning end face 1111 and the connecting face 1112.
