Abstract

The utility model discloses a novel three-dimensional plain bumper of disappearance mould, including the bottom support, plain bumper vibration body passes through air spring and installs at the top of bottom support, but the sand box of packing into in plain bumper vibration body, and the sand box passes through locking device and plain bumper vibration body is fixed, has the vibrating motor of eccentric block around sand box installation four portions in plain bumper vibration body, still installs the rotary encoder of steerable its eccentric block position on vibrating motor in addition. The utility model discloses a novel three-dimensional plain bumper of disappearance mould utilizes rotary encoder adjustment vibrating motor to go up the position of eccentric block to the direction of adjustment plain bumper lets the molding sand fill from the direction of each difference to the blank mould, makes to fill no dead angle, improves the foundry goods yield. The vibrating body of the vibrating table is in flexible connection with the bottom support through the air spring, and when the vibrating motor vibrates, impact on the bottom support can be reduced.

Description

Novel three-dimensional plain bumper of disappearance mould

Technical Field

The utility model relates to a lost foam casting production facility field, specific novel three-dimensional plain bumper of lost foam that says so relates to in this field.

Background

In the lost foam casting production process, the jolt ramming table is indispensable equipment, the manufactured white mold is placed into the jolt ramming table, added molding sand is jolted and compacted by using a vibrating motor in the jolt ramming table, and the jolt ramming fastening degree directly influences the yield of the cast product after pouring.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a novel three-dimensional plain bumper of disappearance mould is provided exactly.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a novel three-dimensional plain bumper of disappearance mould, its improvement part lies in: the vibrating body of the vibrating table is installed on the top of the bottom support through an air spring, a sand box can be installed in the vibrating body of the vibrating table, the sand box is fixed with the vibrating body of the vibrating table through a locking device, a vibrating motor with eccentric blocks is installed on four parts of the vibrating motor surrounding the sand box in the vibrating body of the vibrating table, and a rotary encoder capable of controlling the positions of the eccentric blocks is further installed on the vibrating motor.

The utility model has the advantages that:

the utility model discloses a novel three-dimensional plain bumper of disappearance mould utilizes rotary encoder adjustment vibrating motor to go up the position of eccentric block to the direction of adjustment plain bumper lets the molding sand fill from the direction of each difference to the blank mould, makes to fill no dead angle, improves the foundry goods yield. The vibrating body of the vibrating table is in flexible connection with the bottom support through the air spring, and when the vibrating motor vibrates, impact on the bottom support can be reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Embodiment 1, as shown in fig. 1-3, this embodiment discloses a novel three-dimensional jolt ramming table of lost foam, which comprises a bottom bracket 2, a jolt ramming table vibrating body 1 is installed on the top of the bottom bracket through an air spring 4, a sand box can be installed in the jolt ramming table vibrating body, the sand box is fixed with the jolt ramming table vibrating body through a locking device 3, a vibrating motor 5 with eccentric blocks is installed around the sand box in the jolt ramming table vibrating body, in addition, a rotary encoder capable of controlling the positions of the eccentric blocks is also installed on the vibrating motor, and the rotary encoder makes the vibrating directions of the vibrating motors different by adjusting the positions of the eccentric blocks so as to change the moving direction of molding sand.

The bottom bracket in the embodiment is used for supporting the vibrating body of the vibrating table and the sand box; the locking device tightly fixes the sand box and the vibrating body of the vibrating table together, so that the sand box can be stable during vibration; when the sand box needs to be compacted and added with sand in the vibrating body of the compaction table, the vibrating motor provides a power source to compact the molding sand; the eccentric block positions of the four vibrating motors are controlled by the rotary encoder, and the eccentric block positions of the four vibrating motors are different, so that the generated vibrating directions are different, the motion direction of the molding sand is changed, and the molding sand can be filled in the white mold from different directions.

Claims

1. The utility model provides a novel three-dimensional plain bumper of disappearance mould which characterized in that: the vibrating body of the vibrating table is installed on the top of the bottom support through an air spring, a sand box can be installed in the vibrating body of the vibrating table, the sand box is fixed with the vibrating body of the vibrating table through a locking device, a vibrating motor with eccentric blocks is installed on four parts of the vibrating motor surrounding the sand box in the vibrating body of the vibrating table, and a rotary encoder capable of controlling the positions of the eccentric blocks is further installed on the vibrating motor.
