Description

Technical Field

[0001] The present invention relates to the technical field of casting equipment, and in particular to an automatic demolding and cleaning device for castings. Background Art

[0002] Casting is a common metal forming process. In the casting process, demolding and cleaning are key subsequent processes, which directly affect the quality and production efficiency of castings. With the development of industrial automation, the casting industry has an increasing demand for automatic demolding and cleaning equipment. Most of the existing automatic demolding equipment has a complex structure and poor adaptability, making it difficult to meet the production requirements of castings of different sizes. Incomplete mold cleaning will lead to the accumulation of residues, affecting the quality of subsequent castings and even shortening the service life of the mold. Therefore, the present invention provides an automatic demolding and cleaning device for castings. Summary of the Invention

[0003] Aiming at the defects in the prior art, the present invention provides an automatic demolding and cleaning device for castings, which overcomes the problems of being unable to meet the production requirements of castings of different sizes and incomplete mold cleaning, which is likely to affect the quality of subsequent castings.

[0004] To achieve the above object, the present invention provides the following technical solution: An automatic demolding and cleaning device for castings, including a base, on which a separation component, a deployment component, and an auxiliary component are provided. The separation component includes a circular lower base plate and a circular upper base plate, which are symmetrically arranged. Circular sliders are slidably installed on both the circular lower base plate and the circular upper base plate. The deployment component includes an annular support plate, on which 6 adjustment racks are slidably installed in a circumferential array. Arc-shaped side plates are movably provided at the ends of the adjustment racks closest to the axis of the annular support plate. When the 6 arc-shaped side plates are in the closest position, a complete ring plate is formed between the 6 arc-shaped side plates. Fixed units are provided between each arc-shaped side plate and the corresponding adjustment rack, and the fixed units are used to fix the arc-shaped side plate and the corresponding adjustment rack. The auxiliary component includes an auxiliary rotating plate, and an L-shaped scraping plate is fixedly installed at the end of the auxiliary rotating plate.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Circular lower base plate 102 and circular upper base plate 103 are both slidably installed with circular sliders 115. The axes of the circular lower base plate 102, circular upper base plate 103, and circular sliders 115 are on the same straight line. Separation electric cylinders 116 are fixedly installed on both the circular lower base plate 102 and circular upper base plate 103. The end of the piston rod of the separation electric cylinder 116 is fixedly connected to the corresponding circular slider 115. When the circular lower base plate 102 and the corresponding circular slider 115 are fully engaged and when the circular upper base plate 103 and the corresponding circular slider 115 are fully engaged, a complete circular plate is formed respectively.

[0029] In the initial position, the upper surface of the circular lower base plate 102 and the upper surface of the circular slider 115 on the circular lower base plate 102 are on the same plane, and the lower surface of the circular upper base plate 103 and the lower surface of the circular slider 115 on the circular upper base plate 103 are on the same plane.

[0030] Start the cleaning motor 119 corresponding to the circular lower base plate 102 to drive the auxiliary gear 118 to rotate. Under the action of the auxiliary gear ring 117, the circular lower base plate 102 rotates relative to the base 101. Start the cleaning motor 119 corresponding to the circular upper base plate 103 to drive the auxiliary gear 118 to rotate. Under the action of the auxiliary gear ring 117, the circular upper base plate 103 rotates relative to the annular slide plate 108. After the circular lower base plate 102 and the circular upper base plate 103 complete the casting work and the casting cools down, first start the height adjustment motor 111 to drive the height adjustment screw rod 112 to rotate, which makes the annular slide plate 108 move upward, and the circular upper base plate 103 moves upward synchronously. At this time, start the separation electric cylinder 116 corresponding to the circular upper base plate 103 to drive the circular slider 115 on the circular upper base plate 103 to move downward. Under the action of the circular slider 115, the casting is separated from the lower surface of the circular upper base plate 103. Then make the circular upper base plate 103 contact the upper surface of the casting again. Then start the separation electric cylinder 116 corresponding to the circular upper base plate 103 to drive the circular slider 115 to move upward, so that the lower surface of the circular slider 115 on the circular upper base plate 103 is separated from the contact with the casting, that is, the casting is separated from the adhesion with the circular upper base plate 103 and the circular slider 115 on the circular upper base plate 103. Repeat the above steps, start the separation electric cylinder 116 corresponding to the circular lower base plate 102, so that the casting is separated from the adhesion with the upper surface of the circular lower base plate 102 and the upper surface of the circular slider 115 on the circular lower base plate 102 respectively, thus facilitating the removal of the casting.

[0031] An unfolding component is provided on the base 101. The unfolding component includes an annular support plate 121. Six position-adjusting racks 129 are slidably installed on the annular support plate 121 in a circumferential array. An annular sliding frame 120 is slidably installed on the base 101. A displacement lead screw 123 is rotatably installed on the base 101. The displacement lead screw 123 and the annular sliding frame 120 form a screw pair. A displacement motor 122 is fixedly installed on the base 101. The output shaft of the displacement motor 122 is fixedly connected to the displacement lead screw 123. A position-changing gear ring 124 is rotatably installed on the annular sliding frame 120. A position-changing motor 126 is fixedly installed on the annular sliding frame 120. A position-changing gear 125 is fixedly installed on the output shaft of the position-changing motor 126. The position-changing gear 125 and the position-changing gear ring 124 are engaged to form a gear pair. The annular support plate 121 is fixedly installed on the position-changing gear ring 124. The axes of the annular support plate 121 and the position-changing gear ring 124 are on the same straight line.

[0032] A gear set is further provided between the six position-adjusting racks 129. The gear set includes one transmission gear ring 127, six transmission gears 131, and six position-adjusting gears 132. The transmission gear ring 127 and the transmission gears 131 are both rotatably installed on the position-changing gear ring 124. The axes of the transmission gear ring 127 and the annular support plate 121 are on the same straight line. The transmission gears 131 are all engaged with the transmission gear ring 127 to form a gear pair. The position-adjusting gears 132 are fixedly installed on the corresponding transmission gears 131. The transmission gears 131 and the corresponding position-adjusting racks 129 are engaged to form a gear-rack pair. A position-adjusting motor 128 is also fixedly installed on the position-changing gear ring 124. The output shaft of the position-adjusting motor 128 is fixedly connected to the corresponding transmission gear 131.

[0033] Start the displacement motor 122 to drive the displacement lead screw 123 to rotate, which causes the annular sliding frame 120 to move up and down relative to the base 101, and the components on the annular sliding frame 120 move synchronously. Start the position-changing motor 126 to drive the position-changing gear 125 to rotate, which causes the position-changing gear ring 124 to rotate relative to the annular sliding frame 120, and the components on the position-changing gear ring 124 move synchronously. Start the position-adjusting motor 128 to drive the corresponding transmission gear 131 to rotate. Under the action of the transmission gear ring 127, the six transmission gears 131 rotate synchronously, which causes the six position-adjusting gears 132 to rotate synchronously. Under the action of the position-adjusting gears 132, the six position-adjusting racks 129 move synchronously towards the direction close to the axis of the annular support plate 121 or move synchronously away from the axis of the annular support plate 121.

[0034] Arc-shaped side plates 107 are movably arranged at the ends of the position-adjusting rack 129 closest to the axis of the annular support plate 121. When the six arc-shaped side plates 107 are at the closest positions, a complete ring plate is formed between the six arc-shaped side plates 107. Fixed units are arranged between the arc-shaped side plates 107 and the corresponding position-adjusting racks 129. The fixed units are used to fix the arc-shaped side plates 107 and the corresponding position-adjusting racks 129. Each fixed unit includes a fixed sliding seat 133 and a limiting sliding plate 134. The fixed sliding seat 133 is fixedly installed on the arc-shaped surface of the corresponding arc-shaped side plate 107 farthest from the axis of the annular support plate 121, and the limiting sliding plate 134 is slidably installed on the end surface of the corresponding position-adjusting rack 129 closest to the axis of the annular support plate 121. The fixed sliding seat 133 and the corresponding limiting sliding plate 134 are in sliding fit.

[0035] Limit short columns 130 are symmetrically and fixedly arranged on the fixed sliding seat 133. Two through holes for cooperating with the limit short columns 130 are arranged at the end of the position-adjusting rack 129 closest to the axis of the annular support plate 121. The limiting sliding plate 134, the fixed sliding seat 133, and the limit short columns 130 are used to fix the arc-shaped side plate 107 and the corresponding position-adjusting rack 129. A driven rack 143 is rotatably installed on the position-adjusting rack 129. A linkage sliding plate 138 is also slidably installed on the position-adjusting rack 129. A driving rack 141 is fixedly arranged on the linkage sliding plate 138. A driven gear 142 is fixedly arranged on the side of the limiting sliding plate 134. The driving rack 141 and the driven gear 142 are both engaged to form a gear pair.

[0036] A driven sliding plate 137 is also slidably installed on the position-adjusting rack 129. A T-shaped push block 136 is fixedly arranged on the driven sliding plate 137. A separating push rod 135 is fixedly arranged on the fixed sliding seat 133. The T-shaped push block 136 and the separating push rod 135 are used to facilitate the separation of the fixed sliding seat 133 and the position-adjusting rack 129. A second return spring 140 is arranged between the driven sliding plate 137 and the position-adjusting rack 129. A first return spring 139 is arranged between the driven sliding plate 137 and the linkage sliding plate 138. The elastic force of the second return spring 140 is always greater than the elastic force of the first return spring 139. Six limit push blocks 106 are fixedly arranged on the annular support plate 121 in a circumferential array. The limit push blocks 106 are used to limit the positions of the corresponding linkage sliding plates 138.

[0037] In the initial position, the torsion springs between the first reset spring 139 and the second reset spring 140 are not compressed. At this time, the driven slide plate 137 is at the position farthest from the corresponding fixed slide base 133, and the linkage slide plate 138 is at the position farthest from the corresponding fixed slide base 133. Under the action of the transmission rack 141, the driven gear 142, and the driven rack 143, the driven rack 143 is at the position farthest from the corresponding transmission gear 131 at this time. At this time, the fixed slide base 133 and the corresponding limit slide plate 134 are in a joined state, and the limit short post 130 on the fixed slide base 133 and the corresponding through hole on the position adjustment rack 129 are in a joined state. Under the action of the fixed slide base 133, the limit slide plate 134, and the limit short post 130, the arc-shaped side plate 107 and the corresponding position adjustment rack 129 are in a fixed state, and at this time, the T-shaped push block 136 does not contact the corresponding separation push rod 135.

[0038] When the arc-shaped side plate 107 needs to be replaced, start the position adjustment motor 128 to drive the 6 position adjustment racks 129 to move away from the axis of the position change gear ring 124. The components on the position adjustment rack 129 move synchronously, so that the linkage slide plate 138 on the position adjustment rack 129 contacts the corresponding limit push block 106. The position adjustment rack 129 continues to move. The linkage slide plate 138 cannot continue to move under the action of the limit push block 106, and the transmission rack 141 cannot continue to move either. Since the elastic force of the first reset spring 139 is always less than the elastic force of the second reset spring 140, the first reset spring 139 is compressed at this time, and the driven rack 143 moves toward the limit push block 106. Under the action of the transmission rack 141, the driven rack 143 rotates, which in turn causes the driven gear 142 to move. The driven gear 142 moves relative to the position adjustment rack 129, that is, during the synchronous movement of the limit slide plate 134 and the position adjustment rack 129, the limit slide plate 134 also slides relative to the position adjustment rack 129. Finally, the limit slide plate 134 is completely disengaged from the corresponding fixed slide base 133. At this time, the fixed slide base 133 can be removed from the corresponding position adjustment rack 129. If the limit short post 130 on the fixed slide base 133 and the position adjustment rack 129 are stuck and cannot be removed, the position adjustment rack 129 continues to move away from the axis of the position change gear ring 124. At this time, the first reset spring 139 moves to the maximum deformation amount, the second reset spring 140 is compressed, the driven slide plate 137 moves relative to the position adjustment rack 129, and the T-shaped push block 136 moves synchronously. The inclined surface of the T-shaped push block 136 contacts the corresponding separation push rod 135. Under the action of the T-shaped push block 136, the separation push rod 135 moves upward, so that the fixed slide base 133 moves upward, which is convenient for pulling out the limit short post 130 from the position adjustment rack 129.

[0039] After removing the arc-shaped side plate 107, the second reset spring 140 is restored. Then, after engaging the fixed slide 133 and the position-adjusting rack 129 on the new arc-shaped side plate 107, reverse the above steps. The limit slide plate 134 and the fixed slide 133 are re-engaged, thus locking the position of the fixed slide 133, and thereby fixing the position of the arc-shaped side plate 107.

[0040] When the arc-shaped side plate 107 moves to the position farthest from the axis of the position-changing gear ring 124, at this time, the arc-shaped side plates 107 are all located outside the circular lower base plate 102. Thus, when the annular carriage 120 moves up and down, the arc-shaped side plates 107 will not come into contact with the circular lower base plate 102.

[0041] During pouring, first start the displacement motor 122 to adjust the position of the annular carriage 120 so that the lower end surface of the arc-shaped side plate 107 is above the upper surface of the circular lower base plate 102. Then start the position-adjusting motor 128 so that the 6 arc-shaped side plates 107 are in the closest position. At this time, a complete ring plate is formed between the 6 arc-shaped side plates 107. Then continue to start the displacement motor 122 to move the arc-shaped side plates 107 downward until the lower surface of the ring plate formed by the 6 arc-shaped side plates 107 contacts the upper surface of the circular lower base plate 102. At this time, there is no gap between the ring plate and the circular lower base plate 102. Then move the annular slide plate 108 downward, that is, make the circular upper base plate 103 contact the upper surface of the arc-shaped side plate 107. At this time, a casting chamber is formed between the circular lower base plate 102, the circular upper base plate 103, and the arc-shaped side plates 107. Pouring holes are provided at the position of the circular upper base plate 103, and pouring is carried out into this casting chamber through the pouring holes on the circular upper base plate 103.

[0042] After pouring is completed, after the casting in the casting chamber has cooled, first start the position-adjusting motor 128 to move the 6 arc-shaped side plates 107 away from the axis of the position-changing gear ring 124, that is, make the arc-shaped side plates 107 disengage from the side contact with the casting. Then separately make the circular lower base plate 102, the circular upper base plate 103, and the circular slider 115 disengage from the adhesion with the casting.

[0043] An auxiliary component is also provided on the base 101. The auxiliary component includes an auxiliary rotating plate 104. An L-shaped scraper 105 is fixedly installed at the end of the auxiliary rotating plate 104. The L-shaped scraper 105 is composed of a horizontal section and a vertical section. An auxiliary sliding plate 109 is also slidably installed on the base 101. An auxiliary lead screw 114 is rotatably installed on the base 101. The auxiliary lead screw 114 and the auxiliary sliding plate 109 form a screw pair. An auxiliary motor 113 is fixedly installed on the base 101. The output shaft of the auxiliary motor 113 is fixedly connected to the auxiliary lead screw 114. Starting the auxiliary motor 113 to drive the auxiliary lead screw 114 to rotate can make the auxiliary sliding plate 109 move up and down relative to the base 101. The auxiliary rotating plate 104 is rotatably installed on the auxiliary sliding plate 109. A switching motor 110 is fixedly installed on the auxiliary rotating plate 104. The output shaft of the switching motor 110 is fixedly connected to the auxiliary rotating plate 104. The L-shaped scraper 105 is used to clean the residues on the upper surface of the circular lower bottom plate 102, the lower surface of the circular upper bottom plate 103, and the inner arc surface of the arc-shaped side plate 107.

[0044] In the initial position, that is, during pouring, the auxiliary rotating plate 104 and the L-shaped scraper 105 are located outside the circular lower bottom plate 102, and the auxiliary rotating plate 104 and the L-shaped scraper 105 will not affect the movement of the arc-shaped side plate 107.

[0045] After pouring is completed and the casting is removed, first start the positioning motor 128 to make the arc-shaped side plate 107 move to the position farthest from the axis of the switching gear ring 124, then start the switching motor 110 to drive the auxiliary rotating plate 104 to rotate, that is, make the L-shaped scraper 105 rotate to directly below the circular upper bottom plate 103, then start the auxiliary motor 113 to make the auxiliary sliding plate 109 move upward, that is, make the L-shaped scraper 105 move upward. The upper surface of the L-shaped scraper 105 contacts the lower surface of the horizontal section of the circular upper bottom plate 103. Then start the cleaning motor 119 corresponding to the circular upper bottom plate 103 to make the circular upper bottom plate 103 rotate. Under the action of the L-shaped scraper 105, the residues on the lower surface of the circular upper bottom plate 103 are scraped off. Then make the 6 arc-shaped side plates 107 rejoin to form an annular plate. At this time, the vertical section of the L-shaped scraper 105 is located inside the annular plate. Then start the switching motor 110 to drive the auxiliary rotating plate 104 to rotate, so that the vertical section of the L-shaped scraper 105 contacts the inner side surface of the annular plate. Then start the switching motor 126 to drive the switching gear ring 124 to rotate, that is, make the 6 arc-shaped side plates 107 rotate synchronously. During the rotation of the switching gear ring 124, the positioning rack 129 will not contact the height-adjusting lead screw 112 and the auxiliary lead screw 114, that is, the height-adjusting lead screw 112 and the auxiliary lead screw 114 will not affect the rotation of the positioning rack 129 relative to the axis of the switching gear ring 124.

[0046] The arc-shaped side plate 107 rotates, that is, the annular plate formed by the 6 arc-shaped side plates 107 rotates. Under the action of the L-shaped scraper 105, the residues on the inner side surface of the annular plate are scraped off. After the cleaning of the inner side of the arc-shaped side plate 107 is completed, the arc-shaped side plate 107 returns to its initial position, that is, the arc-shaped side plate 107 moves to the position farthest from the axis of the commutation gear ring 124, and the annular carriage 120 moves to the position closest to the lower surface of the base 101. At this time, the arc-shaped side plate 107 is located below the lower surface of the circular lower base plate 102. Then, the switching motor 110 is started to adjust the position of the L-shaped scraper 105 so that the vertical section of the L-shaped scraper 105 is located outside the circular lower base plate 102. Then, the auxiliary motor 113 is started to move the auxiliary slide plate 109 downward, that is, to move the L-shaped scraper 105 downward. The lower surface of the horizontal section of the L-shaped scraper 105 contacts the upper surface of the circular lower base plate 102. Then, the cleaning motor 119 corresponding to the circular lower base plate 102 is started to rotate the circular lower base plate 102. Under the action of the L-shaped scraper 105, the residues on the upper surface of the circular lower base plate 102 are scraped off and cleaned up.

[0047] Working principle: According to the size of the casting to be cast, the corresponding arc-shaped side plate 107 is replaced. Then, the shifting motor 122 and the position-adjusting motor 128 are started, so that after the 6 arc-shaped side plates 107 form an annular plate, it is placed on the circular lower base plate 102. Then, the height-adjusting motor 111 is started to move the circular upper base plate 103 downward, so that the circular lower base plate 102, the circular upper base plate 103, and the arc-shaped side plate 107 form a casting chamber. Then, pouring is carried out into the casting chamber through the pouring hole on the circular upper base plate 103. After the casting to be cast is cooled, first, the arc-shaped side plate 107 is moved to the position farthest from the axis of the commutation gear ring 124. Then, by adjusting the position of the circular slider 115, the casting is separated from the contact with the circular lower base plate 102, the circular upper base plate 103, and the circular slider 115, that is, the casting of the casting is completed.

[0048] Then, the circular lower base plate 102, the circular upper base plate 103, and the arc-shaped side plate 107 are respectively cleaned by the L-shaped scraper 105, and the above steps are repeated to realize continuous casting.

[0049] The present invention is not limited to the above specific embodiments. Those skilled in the art can make various changes without creative labor starting from the above concepts, and all fall within the protection scope of the present invention.
