Description

Technical Field

[0001] The invention belongs to the technical field of iron mold sand coating production, and in particular relates to a casting iron mold sand coating production device and a production process thereof. Background Art

[0002] The iron mold sand-coated casting process has attracted much attention due to its unique advantages. This technology has also been gradually promoted. With the development of the economy, automobile parts casting generally adopts a combination of metal outer molds and sand cores for casting production.

[0003] In the prior art, before each mold closing, the operator generally conducts a visual inspection of the sand box and the mold cavity surface and manually cleans the visible sand particles. Except for the sand core in the cavity, the residual sand on the surface may adhere to the surface of the conveying pulley, resulting in friction of particles during the conveying operation. On the one hand, the wear of the pulley is likely to cause jamming and affect the transmission efficiency. On the other hand, the accumulation of sand particles adhering to the surface is likely to cause loose mold closing in the subsequent stage, and will also cause wear on the sand box surface, affecting its service life, thereby affecting the production efficiency and quality of sand coating on the iron mold of the casting.

[0004] Therefore, we proposed a casting iron mold sand coating production device and its production process to solve the problem that sand on the surface of the existing conveying pulley cannot be automatically cleaned, affecting the conveying effect.

[0015] On the other hand, a production process of a casting iron mold sand coating production device comprises the following steps:

[0016] Step 1: When installing the pulley surface cleaning mechanism as a whole, the lower end of the embedded plate is embedded with the upper end of the box turning frame, and the longitudinal brackets fixedly connected at both ends of the upper surface of the embedded plate are used as support members for installing the connecting trusses. At this time, the fixed sliding rods fixedly connected to the inner side of the longitudinal brackets provide limit support for the horizontal movable frame, and can ensure that the horizontal movable frame maintains a horizontal limit during the movement;

[0017] Step 2: Before or after the sand box conveying operation is completed, the driving motor is controlled to start so that its output shaft rotates, thereby providing power output for the rotation of the rotating wheel plate. At this time, the eccentric connecting rod connected to the surface of the rotating wheel plate rotates eccentrically around the central axis of the rotating wheel plate, and the eccentric connecting rod drives the fixed block connected to the other end to move. At this time, the fixed sliding rod limits the movement of the horizontal movable frame to ensure that the fixed block and the horizontal movable frame connected to the inner side can only realize horizontal sliding movement, thereby realizing the reciprocating horizontal movement of the horizontal movable frame as a whole;

[0018] Step 3: Then the horizontal movable frame drives the cleaning brush assembly connected at the lower end to move as a whole, and the installation cavity and the horizontal movable frame are assembled. The wind knife assembly and the cleaning soft brush connected at the lower end of the connecting panel sweep the surface of the conveying pulley at this time. Since the conveying pulley itself is in a rotating state, it can avoid sweeping dead corners and achieve comprehensive sweeping;

[0019] Step 4: The horizontal movable frame realizes horizontal reciprocating motion when the driving assembly is in operation. At this time, the mounting wing plates connected at both ends of the horizontal movable frame assemble the soft extrusion arc plate. When the horizontal movable frame moves back and forth, the soft extrusion arc plate will reciprocate and squeeze the telescopic bag on the inner side of the longitudinal bracket. At this time, the telescopic bag is squeezed and compressed by external force, and the gas inside the telescopic bag enters the interior of the wind knife assembly through the air guide pipe. At this time, the airflow first passes into the connecting inner cylinder inside the wind knife assembly, and then flows through the air duct and enters the annular groove. The airflow is finally discharged outward through the air outlet and blows to the lower position from two directions. At this time, part of the blown airflow will blow the dust scattered in the air, and on the other hand, part of the airflow blows to the surface of the U-shaped plate, so as to ensure that the particles adhering to the cleaning soft brush are blown off, thereby realizing the self-cleaning of the cleaning soft brush.

DETAILED DESCRIPTION

[0042] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figure 1-19, the present invention provides a technical solution: a production device for casting iron mold coated with sand, including a support base 1. A turnover frame 2 is movably installed at the upper end of the support base 1. A conveying pulley 21 is arranged inside the turnover frame 2, and the conveying pulley 21 is used for transporting the iron mold sand box of the casting.

Auxiliary blowing components 4 are respectively arranged at both ends of the horizontal movable frame 33; Multiple groups of conveying pulleys 21 are used to realize the guiding and conveying of the sand box mold. By adding the pulley surface cleaning mechanism 3, the driving component 331 drives the cleaning component 34 to slide horizontally, which can not only meet the reciprocating brushing of the cleaning component 34 on the surface of the conveying pulley 21 to adhere sand grains and impurities, but also does not affect the normal operation of the conveying pulley 21, and can ensure that the auxiliary blowing component 4 blows on the cleaning component 34, achieving a self-cleaning effect while further suppressing the scattering of the brushed impurities on the surface of the conveying pulley 21 everywhere; It further solves the problem that there is no automatic cleaning of sand grains on the surface of the existing conveying pulley, which affects the conveying effect, can realize the automatic cleaning of sand grains on the roller surface, improve the production quality and efficiency of castings, and extend the service life of sand boxes and pulleys.

[0044] Embodiment 2. Refer to the appendix Figure 1-19 , on the basis of Embodiment 1, in order to realize the overall installation of the cleaning component 34 and the auxiliary blowing component 4: The lower outer surface of the embedded plate 31 is movably embedded with the upper end of the turnover frame 2. Longitudinal brackets 311 are fixedly installed on the upper surfaces of both ends of the embedded plate 31. A connecting truss 312 is fixedly connected to the upper ends of the longitudinal brackets 311. The longitudinal brackets 311 are arranged in two groups, and the inner sides of the two groups of longitudinal brackets 311 are fixedly connected to both ends of the fixed sliding rod 32. An auxiliary support plate 313 is fixedly installed on the outer surface of the middle section of the connecting truss 312. The side view sectional cutting surface of the auxiliary support plate 313 is in a "匚" - shaped structure with the opening downward. A driving component 331 is arranged on the outer surface of one side of the auxiliary support plate 313; In this embodiment, the structure between the embedded plate 31 and the turnover frame 2 is an assembled structure. When the pulley surface cleaning mechanism 3 needs to be installed as a whole, the lower end of the embedded plate 31 is embedded with the upper end of the turnover frame 2. The longitudinal brackets 311 fixedly connected to both ends of the upper surface of the embedded plate 31 serve as the support members for installing the connecting truss 312. At this time, while the fixed sliding rod 32 fixedly connected to the inner side of the longitudinal bracket 311 limits and supports the horizontal movable frame 33, it can ensure that the horizontal movable frame 33 maintains horizontal limit during the moving process.

[0045] Embodiment 3. Refer to the appendix Figure 1-19, on the basis of the second embodiment, in order to realize the overall movement of the cleaning component 34 and reciprocally sweep and clean the surface of the conveying pulley 21: The driving component 331 includes a driving motor 3311, the driving motor 3311 is fixedly installed on the outer surface of the auxiliary support plate 313, a rotating wheel plate 3312 is fixedly installed on the output shaft of the driving motor 3311, an eccentric connecting rod 3313 is rotatably connected to the outer surface of the rotating wheel plate 3312, the other end of the eccentric connecting rod 3313 is rotatably installed with a fixed block 3314, and the outer surface of the fixed block 3314 is fixedly connected to the outer surface of the horizontal movable frame 33. The cleaning component 34 includes connecting inserts 341, and multiple groups of connecting inserts 341 are arranged horizontally and equidistantly with respect to the horizontal movable frame 33. The connecting insert 341 has an "L"-shaped plate structure. A U-shaped plate 342 is fixedly installed on the lower outer surface of the connecting insert 341. The U-shaped plate 342 has a "匚"-shaped plate structure. A cleaning soft brush 343 is fixedly installed at the lower end of the U-shaped plate 342. Through grooves 3421 are opened on the inner wall of the upper end of both the cleaning soft brush 343 and the U-shaped plate 342; in this embodiment, in order to realize the overall horizontal limit movement of the cleaning component 34, the auxiliary support plate 313 plays a supporting role for the driving motor 3311. Before or after the sand box conveying operation, the driving motor 3311 can be controlled to start, so that its output shaft rotates, thereby providing power output for the rotation of the rotating wheel plate 3312. At this time, the eccentric connecting rod 3313 connected to the surface of the rotating wheel plate 3312 rotates eccentrically around the central axis of the rotating wheel plate 3312, and the eccentric connecting rod 3313 drives the fixed block 3314 connected to the other end to move. At this time, the fixed slide rod 32 limits the movement of the horizontal movable frame 33 to ensure that the fixed block 3314 and the horizontally movable frame 33 connected inside can only perform horizontal sliding movement. In this way, the overall reciprocating horizontal movement of the horizontal movable frame 33 is realized. Subsequently, the horizontal movable frame 33 drives the cleaning component 34 connected to the lower end to move as a whole. The installation cavity 431 is assembled with the horizontal movable frame 33. The air knife assembly 432 and the cleaning soft brush 343 connected to the lower end of the connecting insert 341 sweep the surface of the conveying pulley 21 at this time. Since the conveying pulley 21 itself is in a rotating state, sweeping dead corners can be avoided and comprehensive sweeping can be realized. In addition, the reason for opening the through grooves 3421 at the upper end positions of the U-shaped plate 342 and the cleaning soft brush 343 is to ensure that the airflow blown from above can self-clean the cleaning soft brush 343. By virtue of the action of the airflow, the particles accumulated on the cleaning soft brush 343 are blown off; at this time, the problem that there are sand grains on the surface of the existing conveying pulley that cannot be automatically cleaned and affect the conveying effect is solved. The automatic cleaning of the sand grains on the surface of the roller can be realized, the quality and efficiency of the casting production are improved, and the service lives of the sand box and the pulley are prolonged.

[0046] Embodiment 4, referring to the appendix Figure 1-19, on the basis of Embodiment 3, in order to realize the self-cleaning of the cleaning component 34 while further suppressing the flying and scattering of the swept dust: The auxiliary blowing component 4 includes a mounting wing plate 41 and an inclined surface equalizing cover 43. The upper surface of the inclined surface equalizing cover 43 is fixedly connected to the lower surface of the auxiliary support plate 313. The mounting wing plate 41 is in a "C"-shaped plate structure and is detachably installed at both ends of the horizontal movable frame 33. A soft extrusion arc plate 411 is fixedly installed on the outer surface of the mounting wing plate 41. A rubber convex strip is fixedly added to the outer surface of the soft extrusion arc plate 411. A telescopic bladder 42 is arranged outside the soft extrusion arc plate 411. The telescopic bladder 42 is fixedly installed on the inner surface of the longitudinal support 311. An air guide pipe 421 is connected through the inner wall of the telescopic bladder 42. The output end of the air guide pipe 421 is fixedly connected to a sealing joint 4211. The outer surface of the sealing joint 4211 is connected through the inner walls at both ends of the inclined surface equalizing cover 43. An installation cavity 431 is arranged in the inner cavity of the inclined surface equalizing cover 43. The lower outer surface of the inclined surface equalizing cover 43 is an inclined surface. An air knife assembly 432 is installed on the inner wall of the inclined surface. An annular groove 4323 is opened inside the air knife assembly 432. A connecting inner cylinder 4321 is fixedly installed on the inner surface of the annular groove 4323. Both ends of the connecting inner cylinder 4321 are respectively connected to the output end of the air guide pipe 421. An air guiding groove 4322 is opened at the upper end of the connecting inner cylinder 4321. An air outlet 4324 is opened at the lower end of the annular groove 4323 and extends to the outside of the inclined surface equalizing cover 43. A dust blocking arc plate 44 is arranged outside the inclined surface equalizing cover 43. A connecting shaft rod 441 is rotatably installed on the inner wall at the upper end of the dust blocking arc plate 44. Both ends of the connecting shaft rod 441 are respectively fixedly connected to the inner wall of the inclined surface equalizing cover 43;In this embodiment, the horizontal movable frame 33 realizes horizontal reciprocating movement when the driving assembly 331 is in operation. At this time, the mounting wing plates 41 connected at both ends of the horizontal movable frame 33 assemble the soft extrusion arc plate 411. When the horizontal movable frame 33 moves back and forth, the soft extrusion arc plate 411 will reciprocate and squeeze the telescopic bag tube 42 on the inner side of the longitudinal bracket 311. At this time, the telescopic bag tube 42 is squeezed by external force and compressed. At this time, the gas inside the telescopic bag tube 42 enters the interior of the wind knife assembly 432 through the air guide pipe 421. At this time, the airflow first passes into the connecting inner cylinder 4321 inside the wind knife assembly 432, and then the airflow flows through the air guide groove 4322 and enters the annular groove 4323. The airflow finally passes through the air outlet 4324 to the outside The air is blown downward from two directions, and part of the airflow blows the dust in the air, and part of the airflow blows toward the surface of the U-shaped plate 342, so that the particles attached to the cleaning soft brush 343 can be blown off, and the self-cleaning of the cleaning soft brush 343 can be achieved. It is further explained that most of the particles attached to the surface of the cleaning soft brush 343 will be shaken to a certain extent by the horizontal movable frame 33, so as to achieve the shaking off of the particles attached to the surface, which further solves the problem that the sand on the surface of the existing conveying pulley cannot be automatically cleaned, affecting the conveying effect, and can realize the automatic cleaning of the sand on the roller skate surface, improve the production quality and efficiency of castings, and extend the service life of the sand box and the pulley. ;

[0047] For example 5, please refer to Figure 1-19 The present invention also proposes a production process of a casting iron mold sand coating production device, comprising the following steps:

[0048] Step 1: When the pulley surface cleaning mechanism 3 is installed as a whole, the lower end of the embedded plate 31 is embedded with the upper end of the box turning frame 2, and the longitudinal brackets 311 fixedly connected at both ends of the upper surface of the embedded plate 31 are used as support members for installing the connecting trusses 312. At this time, the fixed sliding rods 32 fixedly connected to the inner side of the longitudinal brackets 311 provide limited support for the horizontal movable frame 33, and can ensure that the horizontal movable frame 33 maintains a horizontal limit position during the movement;

[0049] Step 2: Before or after the sand box conveying operation is completed, the driving motor 3311 is controlled to be turned on so that its output shaft rotates, thereby providing power output for the rotation of the rotating wheel plate 3312. At this time, the eccentric connecting rod 3313 connected to the surface of the rotating wheel plate 3312 rotates eccentrically around the central axis of the rotating wheel plate 3312, and the eccentric connecting rod 3313 drives the fixed block 3314 connected to the other end to move. At this time, the fixed slide rod 32 limits the movement of the horizontal movable frame 33 to ensure that the fixed block 3314 and the horizontal movable frame 33 connected to the inner side can only realize horizontal sliding movement, thereby realizing the overall reciprocating horizontal movement of the horizontal movable frame 33;

[0050] Step 3: Then the horizontal movable frame 33 drives the cleaning brush assembly 34 connected at the lower end to move as a whole, and the installation cavity 431 is assembled with the horizontal movable frame 33. The wind knife assembly 432 and the cleaning soft brush 343 connected at the lower end of the connecting panel 341 sweep the surface of the conveying pulley 21. Since the conveying pulley 21 itself is in a rotating state, it can avoid sweeping dead corners and achieve comprehensive sweeping;

[0051] Step 4: The horizontal movable frame 33 realizes horizontal reciprocating movement when the driving assembly 331 is in operation. At this time, the mounting wing plates 41 connected at both ends of the horizontal movable frame 33 assemble the soft extrusion arc plate 411. When the horizontal movable frame 33 reciprocates, the soft extrusion arc plate 411 reciprocates and squeezes the telescopic capsule 42 on the inner side of the longitudinal bracket 311. At this time, the telescopic capsule 42 is compressed by the external force, and the gas inside the telescopic capsule 42 enters the interior of the wind knife assembly 432 through the air guide pipe 421. At this time, the airflow first enters the connecting inner cylinder 4321 inside the wind knife assembly 432, and then flows through the air inlet groove 4322 and enters the annular groove 4323. The airflow is finally discharged outward through the air outlet 4324 and blows toward the lower position from two directions. At this time, part of the airflow will blow the dust scattered in the air, and on the other hand, part of the airflow blows toward the surface of the U-shaped plate 342, so as to ensure that the particles adhering to the cleaning soft brush 343 are blown off, thereby realizing the self-cleaning of the cleaning soft brush 343.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

7. A production process of a casting iron mold sand-coated production device, which is realized based on the casting iron mold sand-coated production device described in claim 6, characterized in that: The production process of the casting iron mold sand coating production device includes the following steps: Step 1: When installing the pulley surface cleaning mechanism (3) as a whole, the lower end of the embedded plate (31) is embedded with the upper end of the mold turning frame (2). The longitudinal supports (311) fixedly connected to both ends of the upper surface of the embedded plate (31) serve as the supports of the installation connection truss (312). At this time, while the fixed sliding rod (32) fixedly connected to the inner side of the longitudinal support (311) limits and supports the horizontal movable frame (33), it can ensure that the horizontal movable frame (33) maintains horizontal limitation during the movement process. Step 2: Before or after the sand box conveying operation is completed, the driving motor (3311) is controlled to be turned on so that its output shaft rotates, thereby providing power output for the rotation of the rotating wheel plate (3312). At this time, the eccentric connecting rod (3313) connected to the surface of the rotating wheel plate (3312) rotates eccentrically around the central axis of the rotating wheel plate (3312), and the eccentric connecting rod (3313) drives the fixed block (3314) connected to the other end to move. At this time, the fixed sliding rod (32) limits the movement of the horizontal movable frame (33) to ensure that the fixed block (3314) and the horizontal movable frame (33) connected to the inner side can only realize horizontal sliding movement, thereby realizing the overall reciprocating horizontal movement of the horizontal movable frame (33); Step 3: The horizontal movable frame (33) then drives the cleaning brush assembly (34) connected to the lower end to move as a whole, and the installation cavity (431) and the horizontal movable frame (33) are assembled, and the wind knife assembly (432) and the cleaning soft brush (343) connected to the lower end of the connecting panel (341) sweep the surface of the conveying pulley (21). Since the conveying pulley (21) itself is in a rotating state, it can avoid sweeping blind spots and achieve comprehensive sweeping; Step 4: The horizontal movable frame (33) realizes horizontal reciprocating motion when the driving assembly (331) is in operation. At this time, the mounting wing plates (41) connected at both ends of the horizontal movable frame (33) are assembled to the soft extrusion arc plate (411). When the horizontal movable frame (33) reciprocates, the soft extrusion arc plate (411) reciprocates and squeezes the telescopic capsule (42) inside the longitudinal bracket (311). At this time, the telescopic capsule (42) is compressed by the external force, and the gas inside the telescopic capsule (42) enters the wind knife assembly (432) through the air guide pipe (421). ), at this time, the airflow first passes into the connecting inner cylinder (4321) inside the air knife assembly (432), and then flows through the air induction groove (4322) and enters the annular groove (4323). The airflow is finally discharged outward through the air outlet (4324) and blows to the lower position from two directions. At this time, part of the blown airflow will blow the dust scattered in the air, and on the other hand, part of the airflow will blow to the surface of the U-shaped plate (342), so as to ensure that the particles adhering to the cleaning soft brush (343) are blown off, thereby realizing the self-cleaning of the cleaning soft brush (343).
