Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel production technology, and in particular to a grinding wheel production pressing mold. Background Technology

[0002] During the production of grinding wheels, pressing molds are required. In the grinding wheel pressing process, after the material is fed, pressing is usually carried out directly, which can easily cause uneven material distribution and affect the quality of the grinding wheel.

[0003] Chinese patent document (authorization announcement number CN213562036U) discloses a pressing mold for grinding wheel production. The mold body has a grinding wheel forming cavity, and the interior of the mold body is filled with a heat-conducting medium. Cooling water pipes are installed within the heat-conducting medium, spirally coiled inside the mold body. Heat dissipation holes are formed on the outer wall of the mold body. Several temperature measuring holes are formed on the mold body. Handles are fixed to both sides of the mold body with bolts. A mold core column penetrates the center of the mold body and is pressed against the bottom center of the mold. A through hole is formed in the center of the mold body to mate with the mold core column. A top pressure block is fitted into the bottom of the mold body. The advantages of this invention, using the above technical solution, are: it can accurately determine the heating temperature, accelerates heat dissipation after grinding wheel pressing, and is easy to transport. It is convenient to use, highly practical, and suitable for widespread application. However, although it can press and form, it lacks vibration functionality and the ability to improve material uniformity. Utility Model Content

[0004] The purpose of this utility model is to provide a pressing mold for grinding wheel production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding wheel production pressing mold, comprising a lower storage mold and an upper pressing mold for grinding wheel production, wherein an insulation shell is provided on the outer periphery of the lower storage mold, the insulation shell is detachably connected to the lower storage mold via a connecting ring plate, a plurality of lifting lugs are connected between the insulation shell and the lower storage mold, a servo motor is connected on the outer periphery of the insulation shell, the output shaft of the servo motor passes through the insulation shell and the lifting lugs and is connected to a rotating rod, and an eccentric wheel for striking the lower storage mold is connected on the outer periphery of the rotating rod;

[0006] The inner wall of the insulation shell is equipped with multiple heating tubes for heating, and a heat-resistant fan is installed on the outer periphery of the insulation shell. The heat-resistant fan is connected to the insulation shell through two ventilation pipes with solenoid valves. The insulation shell is connected and fixed to the upper pressure mold through a power assembly.

[0007] As a preferred embodiment, the power combination includes two electric push rods connected to the outer periphery of the insulation shell, and a connecting plate connected to the top of the moving part of the electric push rod. The connecting plate is connected and fixed to the upper pressing mold through a connecting block.

[0008] As a preferred embodiment, a cross-shaped counterweight plate is provided below the lower storage mold, and two side support plates are welded to the top of the counterweight plate. The side support plates are rotatably connected to the heat preservation shell through a rotating shaft.

[0009] As a preferred embodiment, a forward and reverse motor is connected to the side of the side support plate, and the output shaft of the forward and reverse motor passes through the side support plate and is connected and fixed to the rotating shaft.

[0010] As a preferred embodiment, the inner wall of the insulation shell is also connected to an electric push rod, and a circular channel is opened at the bottom of the lower storage mold, with a sealing circular plate installed in the inner cavity of the circular channel.

[0011] In a preferred embodiment, a central column is welded to the top of the sealing circular plate, and the moving part of the electric actuator is connected and fixed to the sealing circular plate.

[0012] As a preferred embodiment, the top end of the connecting ring plate is connected to a water inlet pipe with a control valve, and the bottom end of the insulation shell is connected to a water outlet pipe with a solenoid valve.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This grinding wheel produces pressing molds thanks to the design of a servo motor, eccentric wheel, and forward and reverse motors. The servo motor drives the rotating rod and eccentric wheel to rotate, intermittently vibrating the lower storage mold to improve the uniformity of the material inside the lower storage mold. The forward and reverse motors drive the rotating shaft and the insulation shell to rotate, changing the position of the material. Combined with the vibration, this can further improve the uniformity of the material.

[0015] Thanks to the design of the heating tube and the heat-resistant fan, the heating tube can heat the environment inside the insulation shell, thereby heating the lower storage mold inside the insulation shell and indirectly changing the temperature of the material inside the lower storage mold. The heat-resistant fan, together with two ventilation pipes, can assist the air to flow and improve the temperature uniformity. In the later stage, the heating tube can be turned off and cold water can be introduced into the insulation shell through the water inlet pipe to achieve cooling.

[0016] Thanks to the power combination and the design of the forward and reverse motors, the retraction of the electric push rod causes the upper pressure mold to move downward, pressing and shaping the material in the lower storage mold. After the grinding wheel is formed, the forward and reverse motors drive the insulation shell to rotate 180 degrees, so that the upper pressure mold is below the lower storage mold. The electric push rod is then extended, and the electric push rod drives the sealing disc and the central column to move. Then, the grinding wheel that has been processed is manually removed.

[0017] This grinding wheel is used to produce pressing molds, which can not only improve the uniformity of materials, but also regulate temperature. Attached Figure Description

The electric push rods 121 are controlled to retract, so that the upper pressing mold 2 moves down to press the material.

[0031] To allow the mold to rotate and meet different usage needs, a cross-shaped counterweight plate 13 is installed below the lower storage mold 1.

The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0035] Working principle

[0036] The grinding wheel produces a pressing mold. The heating tube 9 and the heat-resistant fan 10 are turned on in advance. Then, the material is introduced into the lower storage mold 1, and the electric push rod 121 is controlled to retract, so that the upper pressing mold 2 moves down to press the material. During this process, the servo motor 6 and the forward and reverse motor 15 are turned on. The servo motor 6 drives the rotating rod 7 and the eccentric wheel 8 to rotate, indirectly hitting the lower storage mold 1. The forward and reverse motor 15 drives the rotating shaft and the heat insulation shell 3 to rotate, ensuring the uniformity of the material.

[0037] After the grinding wheel is formed, the solenoid valves of the forward and reverse motor 15, servo motor 6, heating pipe 9, and ventilation pipe 11 are closed. Water is introduced into the insulation shell 3 through the water inlet pipe 19 to cool it down. The drain pipe 20 is opened to change the water. After draining, the forward and reverse motor 15 is controlled to rotate the insulation shell 3 180 degrees so that the upper pressure mold 2 is below the lower storage mold 1. The electric push rod 121 is controlled to extend, and the electric push rod 16 is controlled to move the sealing plate 17 and the central column 18. Then the formed grinding wheel is manually removed.
