Description

Technical Field

[0001] The present application relates to the field of lost foam runners, and in particular to a lost foam runner interface glue coating device. Background Art

[0002] The lost foam casting process is a relatively mature process. Usually, the lost foam is placed in the sand and needs to be connected with a runner. The molten iron poured vertically is transferred horizontally into the lost foam through the runner to melt the lost foam. After the molten iron is cooled, it becomes the shape of the lost foam. The runner is also melted when the molten iron is poured.

[0003] Reference Figure 1 In the casting process, the runner system includes a sprue 7 and a cross runner 8. The lower end of the sprue 7 is closed, and the upper end is used to communicate with the pouring cup. The lower end of the side wall of the sprue 7 is symmetrically provided with an inner joint 71. The cross runner 8 is symmetrically arranged on both sides of the sprue. An external pipe 81 is arranged at one end of the cross runner close to the sprue, and the inner joint 71 is plugged into the external pipe 81. When the runner system is connected and assembled today, the inner joint 71 is docked with the external pipe 81. Before plugging, a small amount of adhesive is manually applied to the outer wall of the inner joint 71 to make the connection between the two become one.

[0004] With respect to the above technical solution, the inventor believes that manually applying glue to the outer wall of the inner joint is labor-intensive and has low gluing efficiency. Summary of the invention

[0017] The longitudinal driving member drives the movable base to move uniformly from the starting end to the end of the workbench at a speed v, the laser sensor emitting part emits laser light, and the laser sensor receiving part receives laser light. When the inner joint passes through the laser sensor emitting part and the laser sensor receiving part, the inner joint blocks the laser light emitted by the laser sensor emitting part, and the processor generates a time t for the inner joint to block the laser light.

[0018] The distance between the two ends of the inner joints facing each other is L, the outer diameter of the inner joint is D, the angle between the axial direction of the inner joint and the width direction of the workbench is α, and the above L and D are recorded into the processor;

[0027] By adopting the above technical solution, the movement of the connecting vertical plate drives the brush ring and the brush hairs to move. During the gluing process, the brush hairs produce elastic deformation and abut against the outer wall circumference of the inner joint, which is beneficial to improve the uniformity of gluing.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

Keep the inner joint and the brushing assembly coaxial, drive the two brushing assemblies toward each other through the driving mechanism, and when the brushing assembly contacts the peripheral surface of the inner joint, glue is applied to the outer wall of the inner joint. After the glue is applied, the two brushing assemblies are driven away from each other through the driving mechanism, so that the sprue is easily removed from the workbench. Using machinery instead of manual labor to apply glue reduces labor intensity and improves glue application efficiency.

[0030] 2. Through the setting of the driving component, the two sliding plates can be controlled to move synchronously in the center. The movement of the sliding plate drives the movement of the connecting vertical plate, and the movement of the connecting vertical plate drives the painting component, so that the two painting components can move synchronously in the center to ensure that the glue coating on the internal joints on both sides of the straight runner is uniform.

[0031] 3.

After the glue is applied, the two brush assemblies 4 are driven away from each other by the driving mechanism 5, so that the sprue 7 can be removed from the workbench 1.

[0051] S6 , the rotating motor 62 receives the electrical signal from the processor 151 and rotates a corresponding angle according to the unique value of α to achieve deflection correction of the sprue 7 .

[0052] In this way, by deflecting and correcting the straight runner 7, the axial direction of the inner joint 71 is ensured to be consistent with the width direction of the fixed frame 3, thereby ensuring the position alignment of the inner joint 71 and the brushing component 4, avoiding interference with the movement of the brushing component 4, and at the same time improving the uniformity of the glue coating on the outer wall of the inner joint 71.

[0059] During the movement of the mobile base 11, the correction mechanism 6 corrects the deflection of the sprue 7 to ensure that the axial direction of the inner joint 71 is the same as the width direction of the fixed frame 3, and the two brushing assemblies 4 are driven toward each other by the driving mechanism 5. When the brushing assemblies 4 contact the circumference of the inner joint 71, the outer wall of the inner joint 71 is coated with glue. After the glue coating is completed, the two brushing assemblies 4 are driven away from each other by the driving mechanism 5, so that the sprue 7 can be removed from the workbench 1.

[0060] After the outer wall of the inner joint 71 is coated with glue, the sprue 7 is driven by the longitudinal drive member 12 to continue to move forward along the workbench 1, and the sprue 7 is transported to the next station to facilitate the assembly of the subsequent runner system. After the transportation is completed, the longitudinal drive member 12 drives the mobile base 11 back to the initial position to carry out the coating of glue on the interface of the next sprue 7. The present application uses machinery to replace manual labor for coating, which reduces labor intensity and improves coating efficiency.

When the inner joint (71) passes through the laser sensor emitting part (13) and the laser sensor receiving part (14), the inner joint (71) blocks the laser light emitted by the laser sensor emitting part (13), and the processor (151) generates a time t for which the inner joint (71) blocks the laser light. The distance between the two ends of the inner joints (71) facing each other is L, the outer diameter of the inner joint (71) is D, and the angle between the axial direction of the inner joint (71) and the width direction of the workbench (1) is α, and L and D are recorded in the processor (151); The processor (151) is based on the formula + =vt, find two solutions of α, and the two solutions of α are complementary. The above two solutions of α are used as the first basis; The camera (15) takes a bird's-eye view of the inner joint (71) and sends the captured image information to the processor (151). The processor (151) determines whether α is an acute angle or an obtuse angle and uses the determination result as a second basis. The processor (151) finally determines a unique value of α according to the first basis and the second basis, and sends an electrical signal; The rotating motor (62) receives the electrical signal from the processor (151) and rotates a corresponding angle according to the unique value of α, thereby achieving deflection correction of the sprue (7).

3. The lost foam runner interface glue coating device according to claim 1, characterized in that: The clamping mechanism (2) comprises clamping arc plates (21) symmetrically arranged on the rotating disk (61), the clamping arc plates (21) being slidably connected to the rotating disk (61) along the radial direction of the rotating disk (61), and the two ends of the clamping arc plates (21) facing away from each other are connected to a clamping cylinder (22).

4. The lost foam runner interface glue coating device according to claim 1, characterized in that: The painting brush assembly (4) comprises a painting brush ring (41) and painting brush bristles (42) arranged on the inner ring of the painting brush ring (41); the inner ring diameter of the painting brush ring (41) is larger than the outer diameter of the inner joint (71); the inner ring diameter formed by the painting brush bristles (42) is smaller than the outer diameter of the inner joint (71); the painting brush ring (41) is fixed to the lower end of the connecting vertical plate (511).
