Description

Technical Field

[0001] This utility model relates to the technical field of foot valve body casting device, and more specifically, to a casting and forming mechanism for the upper valve body of a foot valve. Background Technology

[0002] A foot valve is a valve used to control the flow of fluid into a pipeline. It is usually installed at the inlet of a water source or pump to prevent backflow and maintain the liquid in the pipeline. The foot valve works on the basis of pressure difference.

[0003] Currently, casting molding mechanisms are required in the casting process of foot valve bodies. However, commonly used casting molding mechanisms occupy a large area and lack stability and accuracy in the conveying and moving of the formed valve body. For example, CN117680660 A discloses a casting molding device for a foot valve body, which includes a base, a die component fixedly connected to the top of the base, a punch component provided on the side of the die component, a bottom of the punch component fixedly connected to the base, a cutting component fixedly connected to the top of the punch component, a ventilation component rotatably connected to the side of the punch component, and a grinding component provided on the side of the punch component away from the die component.

[0004] As can be seen from the above-disclosed scheme, the punch fixes the formed valve body by negative pressure adsorption. However, the surface of the formed valve body is not planar, and the strength of its negative pressure adsorption is limited. This may cause the formed valve body to move or fall off during the rotation of the punch, thereby reducing the stability and accuracy of the valve body's valve delivery. Furthermore, the casting forming mechanism integrates casting components, ventilation components, cutting components, and grinding components. Not only does it occupy a large area, but after the integration of various components, the pipelines are not easy to arrange, which also brings great inconvenience to later maintenance. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a casting and forming mechanism for the upper valve body of a foot valve. This casting and forming mechanism for the upper valve body of a foot valve can rotate in steps through a turntable, support column, and mounting plate, thereby enabling multiple punches to rotate synchronously. This not only facilitates the casting of the valve body but also allows for the cutting and grinding of other formed valve bodies, improving the stability and accuracy of the valve body's conveying. Furthermore, the machine base and top plate facilitate the arrangement of the valve body casting and forming mechanism components, reducing its footprint and simplifying pipeline layout and subsequent maintenance.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0009] Furthermore, one end of the support column is fixedly connected to a mounting plate, the surface of the mounting plate is provided with a positioning groove, and an electromagnetic adsorption disk is fixedly embedded at the bottom of the positioning groove. After being powered on, the electromagnetic adsorption disk can quickly fix the installation position of the punch body through electromagnetic adsorption force, thereby improving the efficiency of mold assembly and disassembly.

[0010] Furthermore, the bottom of the rotating groove is fixedly connected to an installation chamber, and a stepper motor is fixedly installed on the inner wall of the installation chamber. A drive gear is fixedly installed at the output end of the stepper motor.

[0011] Furthermore, the bottom of the rotating groove has an annular guide groove with a semi-circular cross-sectional shape. The inner wall of the guide groove is in rolling contact with the surface of the ball. The guide groove can increase the contact area with the ball and improve the support stability.

[0012] Furthermore, an anti-detachment ring is fixedly connected to the inner wall of the side of the rotating groove. The surface of the anti-detachment ring is slidably connected to the inner wall of the limiting groove. The anti-detachment ring and the limiting groove can prevent the turntable from moving upward.

This not only facilitates the casting of the forming valve body, but also allows for the cutting and grinding of other forming valve bodies, thereby improving the conveying stability and accuracy of the forming valve body.

[0016] (2) The arrangement of valve body casting mechanism components by setting the machine body and top plate in this scheme not only reduces its footprint, but also facilitates pipeline layout and subsequent maintenance. Attached Figure Description

Then, the molten metal is added to the cavity of the concave mold body 4 and the convex mold body 5 through the discharge telescopic rod 32. After cooling, the valve body is formed. After the mold is opened, the stepper motor 16 drives the drive gear 17 to rotate clockwise. The clockwise rotation of the drive gear 17 drives the driven gear 29 to rotate counterclockwise. This causes the turntable 21 and mounting plate 23 to rotate 90 degrees clockwise. The formed valve body is then rotated to the bottom of the cutting assembly for cutting. The punch body 5, after being molded with the concave mold body 4, continues to cast the valve body. After completion, it continues to rotate counterclockwise in the same way as described above, so that the formed valve body rotates to the bottom of the cutting assembly.
