Description

Technical Field

[0001] The present application relates to the field of lost foam automatic assembly equipment, and in particular to a wax mold shaft core positioning device. Background Art

[0002] Lost foam casting is a casting method in which paraffin wax or foam models with similar size and shape to the casting are bonded together to form a model cluster, coated with refractory material and dried, and then buried in dry quartz sand for vibration molding. The model is then cast under negative pressure to vaporize the model, and liquid metal occupies the model position. The casting is then solidified and cooled to form a casting.

[0003] During the assembly of the wax lost foam, due to the long length and large volume of the runner component, it is easy to cause serious deflection of the runner top, causing the runner component to deviate from the vertical axis. As a result, the position consistency of the wax model assembly process cannot be guaranteed during the automated production process, thereby reducing the casting quality of the casting and increasing production costs.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the existing wax lost foam is prone to deviation from the axis during the assembly process, thereby reducing the production quality of the casting and increasing the production cost of the casting. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a wax mold shaft core positioning device.

[0006] This application provides a wax mold shaft core positioning device, which adopts the following technical solutions:

[0007] The cam is secured to the upper edge of the ladder by means of a latching mechanism, and the cam has a first end fixed to the lower edge of the ladder by means of a latching mechanism, and the cam has a second end fixed to the lower edge of the ladder by means of a latching mechanism.

[0008] By adopting the above technical solution, the staff will place the runner piece on the rotating platform and preliminarily position the runner piece through the guide groove and the first guide bevel of the guide piece. Then, the lifting drive assembly drives the rotating connection assembly to abut against the limit plate and pushes the limit plate to squeeze the spring. The limit plate drives the rotating shaft and the positioning block to move in the direction close to the runner piece, so that the positioning block is inserted into the positioning groove. The setting of the second guide bevel and the third guide bevel allows the positioning block to align the runner piece during the insertion into the positioning groove, thereby positioning the runner piece on the axis core, reducing the runner piece from deviating from the axis core, and thus improving the casting quality of the casting. The staff can adjust the downward pressure of the positioning block on the runner piece by changing the preload of the spring, thereby reducing the deformation of the runner piece and further improving the production quality of the casting. The rotating connection, combined bearing and rotating platform are provided so that the runner piece can rotate horizontally after the axis core is positioned, which facilitates the staff to assemble the wax lost foam.

[0009] Preferably, a mounting hole communicating with the guide groove is provided on the guide member, the combined bearing is arranged in the mounting hole, and the rotating shaft and the positioning block pass through the mounting hole and extend into the guide groove.

[0010] By adopting the above technical solution, the rotating shaft and the positioning block abut against the runner component through the mounting hole, thereby achieving the positioning of the axis core of the runner component.

[0011] Preferably, the lifting drive mechanism includes a cylinder arranged on the guide member and a connecting plate arranged on the telescopic end of the cylinder, and the connecting plate is connected to the rotating connecting assembly.

[0012] By adopting the above technical solution, the cylinder drives the connecting plate to move, and the connecting plate drives the rotating connecting assembly to push the limit plate, so that the positioning block is inserted into the positioning groove, thereby realizing the axial core positioning of the runner component.

[0013] Preferably, the rotating connection component is a universal bearing, the fixed end of the universal bearing is arranged on the connecting plate, and the movable end of the universal bearing is in contact with the limiting plate.

[0014] By adopting the above technical solution, the universal bearing can still rotate horizontally under the condition of radial force, so that the runner component can rotate horizontally smoothly, which is convenient for the staff to assemble the wax lost foam.

[0015] Preferably, an L-shaped lifting plate is provided on the connecting plate, and a through hole is opened at one end of the lifting plate away from the connecting plate, and the rotating shaft passes through the through hole. The end of the lifting plate away from the connecting plate is used to drive the limiting plate to move in a direction away from the runner member.

[0016] By adopting the above technical solution, when the cylinder drives the connecting plate and universal bearing to move away from the runner, the spring pushes the limit plate to move away from the runner. However, the distance between the positioning block and the runner is relatively close, making it difficult for workers to remove the casting after casting is completed. The lifting plate is arranged so that when the connecting plate moves away from the runner, the limit plate abuts the lifting plate, driving the limit plate away from the runner, thereby increasing the distance between the positioning block and the runner, making it easier for workers to remove the casting after casting is completed.

[0017] Preferably, the mounting frame includes a base plate, a support plate connected to the base plate, and a reinforcement plate, the guide member is arranged at one end of the support plate away from the base plate, and the reinforcement plates are connected to the base plate and the support plate.

[0018] By adopting the above technical solution, the base plate and the support plate are used to support the guide member, and the provision of the reinforcement plate improves the stability of the mounting frame, thereby improving the operational stability of the guide member and the positioning assembly.

[0019] Preferably, the rotating platform includes a mounting base, a placement plate and a connecting shaft, one end of the connecting shaft is fixedly connected to the placement plate, and the other end is rotatably connected to the mounting base via a bearing.

[0020] By adopting the above technical solution, the runner piece is placed on the placement plate, and the mounting base supports the placement plate and the connecting shaft. The placement plate is rotatably connected to the mounting base through the connecting shaft and the bearing, thereby facilitating the horizontal rotation of the runner piece.

[0021] Preferably, an installation positioning assembly is provided on the mounting base, and the installation positioning assembly includes at least three adjustment blocks and a positioning plate. The multiple adjustment blocks are arranged in a circular array on the mounting base, and the adjustment blocks are provided with adjustment holes. Bolts pass through the adjustment holes to adjust the position of the positioning plate, so as to align the center of the positioning plate with the center of the mounting base. The positioning plate is provided with multiple first positioning holes, and the placement plate is provided with multiple second positioning holes. Positioning rods are inserted into the first positioning holes and the second positioning holes.

[0022] By adopting the above technical solution, the setting of the installation positioning assembly makes it convenient for the staff to adjust the position of the positioning plate through the adjustment block and the bolt, so that the placement plate is quickly positioned and connected to the positioning plate through the positioning rod, thereby facilitating the rapid coaxial installation of the placement plate and the mounting base, thereby improving the installation efficiency of the rotating platform and facilitating the stable operation of the rotating platform, thereby improving the stability of the runner part during rotation.

[0023] Preferably, a limiting groove is provided on the placement plate, a limiting block is provided on the runner member, the limiting block is engaged with the limiting groove, and the limiting groove is provided at the center of the placement plate.

[0024] By adopting the above technical solution, the runner part is located at the center of the placement plate through the setting of the limit groove and the limit block, thereby improving the stability of the runner part during rotation, which is beneficial to improving the accuracy of the wax lost foam assembly process.

[0025] In summary, this application has the following beneficial technical effects:

[0026] 1.

[0027] 2. The staff can adjust the downward positioning force of the positioning block on the runner by changing the preload force of the spring, thereby reducing the deformation of the runner and further improving the production quality of the casting;

[0028] 3. The setting of universal bearings, combined bearings and rotating platforms makes it easy for workers to rotate the positioned runner parts, which is beneficial for workers to assemble the wax lost foam, thereby improving the production efficiency of castings.
