Description

Technical Field

[0001] The present invention relates to the field of casting, and particularly to a core for casting an intercooler air chamber and a cleaning device for intercooler air chamber castings. Background Art

[0002] In the casting production of intercooler air chambers, in order to improve efficiency, the method of multiple parts per mold is generally adopted. After casting, multiple independent intercooler air chamber castings can be obtained. The structure of the intercooler air chamber castings is as Figure 11 shown, including two symmetrically arranged intercooler air chamber products. Each intercooler air chamber product includes an air outlet flare section 11 and an air inlet pipe section 12 that are arranged at an angle and communicate with each other. There is a riser between the air outlet flare sections 11 of the two intercooler air chamber products, and a core 16 for forming its internal cavity is provided in the air inlet pipe sections 12 of the two intercooler air chamber products.

[0003] There are two major core problems in the current production: First, the material waste of the core 16 is serious - the core 16 is mainly made of clay supplemented with clinker, plant fibers, etc., and is a disposable consumable. For each casting produced, one core 16 needs to be made and destroyed; Second, the subsequent cleaning process has high risks and low efficiency - after the casting is taken out of the furnace, workers need to operate closely at a high temperature. By manually knocking to remove the riser between the air outlet flare sections 11 of the two intercooler air chambers, and simultaneously destroying the core 16 and manually clamping out its fragments with tools such as clips. This process not only has a serious safety hazard of scalding, but also the high-temperature environment limits continuous operation. In addition, the stability of manual operation is poor, which is likely to cause damage to the casting or incomplete cleaning, ultimately restricting the production safety and overall efficiency. Summary of the Invention

[0004] To solve the above problems, the present invention provides a core for casting an intercooler air chamber and a cleaning device for intercooler air chamber castings.

[0005] The technical solution of the present invention is as follows:

[0006] A core for casting an intercooler air chamber and a cleaning device for intercooler air chamber castings, wherein the core includes a core body, one end of which is set to be adaptable to the inner cavity of the air inlet pipe section of the intercooler air chamber, and a core-taking protrusion is provided on the outer wall of the other end, and both the core body and the core-taking protrusion are made of metal material.

[0007] Through the above structural design, when this core is applied to the casting of the intercooler air chamber, the core on the intercooler air chamber casting can be taken out completely and non-destructively, so as to realize repeated use, and solve the material waste problem of "one core per piece" in the traditional technology; at the same time, the core made of metal material has higher dimensional stability and strength compared with the clay core, which helps to ensure the inner cavity accuracy of the intercooler air chamber casting and withstand the force of the core-taking operation.

[0008] The cleaning device is used for separating the riser and the core from the casting of the intercooler air chamber. The core is the core for casting the intercooler air chamber described above. The cleaning device includes a frame and a cleaning machine thereon. The cleaning machine includes a turnover unit and a cleaning unit on one side thereof.

[0009] Specifically, the turnover unit includes a transverse moving frame and a material receiving mechanism capable of horizontal and vertical movement thereon. The cleaning unit includes a punching mechanism and a limiting mechanism disposed above the material receiving mechanism. The material receiving mechanism is configured to be able to receive the casting of the intercooler air chamber and move upward to cooperate with the limiting mechanism to clamp the casting of the intercooler air chamber tightly. The limiting mechanism is provided with a first avoidance opening. The vertical projection of the punching mechanism is located within the first avoidance opening and is configured to be able to move vertically to cut off the riser. Core pulling mechanisms are further provided on both sides of the punching mechanism. The core pulling mechanism includes a transverse moving seat and a pressing portion and a pulling portion thereon. The pressing portion is configured to be able to horizontally press against the casting of the intercooler air chamber, and the pulling portion is configured to be able to pull out the core in the reverse direction.

[0010] As an implementation manner, multiple groups of cleaning machines are arranged side by side on the frame to synchronously process multiple castings, thereby improving the equipment utilization rate, and the number of cleaning machine workstations can also be flexibly increased or decreased according to the production capacity requirements.

[0011] Furthermore, the core taking protrusion includes two first protrusions arranged oppositely. The pressing portion includes a positioning plate capable of abutting against the casting of the intercooler air chamber, and a through opening for one end of the core provided with the core taking protrusion to pass through is formed on the positioning plate. The pulling portion includes two relatively arranged pulling blocks and a driving machine for driving their horizontal movement, and the two pulling blocks can relatively expand and contract and respectively press against one side of the two first protrusions close to the pressing portion.

[0012] Among them, the two first protrusions arranged oppositely can avoid the core being skewed and jammed due to unilateral force application, and improve the success rate of core extraction.

[0013] A second protrusion is further provided on the outer wall of the core body between the two first protrusions. A guide plate is provided on one side of the positioning plate close to the pulling portion. A guide groove adapted to the second protrusion is horizontally provided on the guide plate, and a third avoidance opening communicating with the through opening and the guide groove is provided on the positioning plate corresponding to the second protrusion. The rotation of the core is restricted by the cooperation of the second protrusion and the guide groove to ensure the accuracy of the pulling direction.

[0014] For the cleaning device of the casting of the intercooler air chamber as described above, a material receiving plate capable of vertical movement is further horizontally provided on one side of the moving seat close to the punching mechanism to catch the core after the core extraction is completed and prevent the core from falling.

[0015] As a further implementation manner, the openings of the two air outlet expansion sections of the casting of the intercooler air chamber are horizontally upward. The above-mentioned limiting mechanism includes a horizontal plate, and two convex strips capable of cooperating with the openings extend downward on the lower side thereof. The first avoidance opening is located between the two convex strips to achieve self-centering and improve the clamping efficiency.

[0016] Specifically, the material receiving mechanism includes a first flat plate vertically slidingly arranged on the movable frame, a second flat plate sliding perpendicular to the moving direction of the movable frame is provided on the first flat plate, a second avoidance opening vertically corresponding to the first avoidance opening is provided on the side of the second flat plate close to the horizontal plate, and two groups of clamping components capable of clamping the lower part of the intercooler air chamber casting are relatively provided on both sides of the second avoidance opening.

[0017] Furthermore, the clamping assembly includes at least two spaced-apart clamping blocks, and the upper sides of the two clamping blocks are respectively provided with upward-opening clamping grooves, so that the receiving structure can smoothly receive the intercooler air chamber casting from the casting equipment, and the center lines of the two clamping grooves along their setting directions are not parallel, that is, the two clamping blocks respectively clamp the lower sides of the air inlet pipe section and the air outlet expansion section of the intercooler air chamber product, so that when the core is extracted along the axis of the air inlet pipe section or the receiving structure transfers the casting, the intercooler air chamber product will not move easily under the action of the two clamping blocks.

[0018] As described above, in the intercooler air chamber casting cleaning equipment, an upper pressure piece is provided below the first flat plate near the side of the horizontal plate. The upper pressure piece is configured to be able to rise to press against the first flat plate, thereby assisting in clamping the casting when the riser is cut, and then descending after the riser is cut.

[0019] The beneficial effect of the present invention is that, through the design of the core removal protrusion on the outer wall of the core body, an effective force fulcrum is provided for the cleaning equipment to pull out the core, so that the metal core can be completely extracted and reused; combined with the reusable characteristics of the metal core and linked with the cleaning equipment, it replaces manual work to complete the casting riser removal and complete core extraction, significantly improving production safety and efficiency.

Detailed implementation manners

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0036] Embodiment 1

[0037] First, the riser of the intercooler air chamber casting 1 to be cleaned in the present invention has been described in the background art. The casting is a high-temperature casting taken out of the foundry, which includes two symmetrically arranged intercooler air chamber products. Each intercooler air chamber product includes an exhaust flare section 11 and an intake pipe port section 12 which are arranged at an angle and communicate with each other. The riser is located between the exhaust flare sections 11 of the two intercooler air chamber products.

[0038] The inlet pipe port section 12 of the two intercooler air chamber products usually has a core 16 that forms its internal cavity. To enable the above-mentioned core 16 to be completely withdrawn from the intercooler air chamber casting 1 for reuse, the present invention provides a core for intercooler air chamber casting, as Figure 12 shown, including a core body 13, one end of which is set to be adaptable to the inner cavity of the inlet pipe port section 12 of the intercooler air chamber, and a core-taking protrusion is provided on the outer wall of the other end. Both the core body 13 and the core-taking protrusion are made of metal.

[0039] Through the change of material and the design of the core-taking protrusion, compared with the core 16, it can withstand the force of the complete removal operation, so that it can be reused, solving the problem of material waste of "one core per piece" in the traditional technology.

[0040] The following introduces the cleaning equipment of the intercooler air chamber casting 1 provided in this embodiment in combination with Figures 1-5 the cleaning equipment. The core to be cleaned by this cleaning equipment is the core for intercooler air chamber casting described above.

[0041] The cleaning equipment includes a frame 3 provided on one side of the casting equipment 2. A cleaning machine is provided on the frame 3, and the cleaning machine includes a turnover unit 4 and a cleaning unit on one side thereof.

[0042] The turnover unit 4 includes a transverse moving frame 41 and a receiving mechanism that can move horizontally and vertically thereon.

[0043] The cleaning unit includes a punching mechanism 5 and a limiting mechanism provided above the receiving mechanism. The receiving mechanism is set to be able to receive the intercooler air chamber casting 1 and move upward to cooperate with the limiting mechanism to clamp the intercooler air chamber casting 1 tightly. A first avoidance opening 512 is provided on the limiting mechanism. The vertical projection of the punching mechanism 5 is located within the first avoidance opening 512, and it is set to be able to move vertically to cut off the riser.

[0044] On both sides of the punching mechanism 5, a core-pulling mechanism 6 is further provided. The core-pulling mechanism 6 includes a transverse moving seat 61 and a pressing part and a pulling part thereon. The pressing part is set to be able to horizontally press against the intercooler air chamber casting 1, and the pulling part is set to be able to pull out the core in the reverse direction.

[0045] Its turnover unit 4 is a three-dimensional positioning structure to accurately transport the intercooler air chamber casting 1 to the processing area of the cleaning unit. A plurality of cleaning machines are arranged side by side on the frame 3 to synchronously process a plurality of intercooler air chamber castings 1, improving the equipment utilization rate, and the number of cleaning machine workstations can also be flexibly increased or decreased according to the production capacity requirements. In this embodiment, two cleaning machines are shown.

[0046] Two sets of guide mechanisms are arranged on the upper and lower parts of the frame 3. The guide mechanisms include a horizontally arranged guide rod and a guide block slidingly arranged thereon. The movable frame 41 is arranged vertically, and its upper and lower ends are respectively connected to the guide blocks of the two guide mechanisms. A ball screw transmission mechanism is also provided between the lower side of one of the movable frames 41 and the frame 3 to drive the movable frame 41 to move along the guide rod, and the two movable frames 41 are connected by a horizontally arranged telescopic cylinder.

[0047] For the limit mechanism, specifically combined with Figure 6 Specifically, the punching mechanism 5 includes a vertically arranged first high-pressure oil cylinder and a punching head 52 driven by the cylinder to move vertically. The limiting mechanism includes a horizontal plate 51. The air outlet expansion sections 11 of the two intercooler air chambers of the intercooler air chamber casting 1 are opened horizontally upward. The lower side of the horizontal plate 51 corresponds to the two openings and has two ridges 511 extending downward that can cooperate with the openings. The first avoidance opening 512 is located between the two ridges 511, so that the punching head 52 can move vertically to cut off the riser located between the two ridges 511. The design of the ridge 511 facilitates self-centering, thereby improving the efficiency of clamping the intercooler air chamber casting 1.

[0048] For the material receiving mechanism, the specific Figure 7 For example, the material receiving mechanism includes a first flat plate 42 which is vertically slidably arranged on one side of the movable frame 41, and a second flat plate 43 which slides perpendicularly to the moving direction of the movable frame 41 is provided on the first flat plate 42, and a second avoidance opening 431 which is vertically corresponding to the first avoidance opening 512 is provided on the side of the second flat plate 43 close to the horizontal plate 51, and two groups of clamping components which can clamp the lower part of the intercooler air chamber casting 1 are relatively provided on both sides of the second avoidance opening 431.

[0049] Specifically, the first flat plate 42 and the second flat plate 43 are respectively arranged horizontally and perpendicular to the moving direction of the movable frame 41. The first flat plate 42 and the movable frame 41 and the second flat plate 43 and the first flat plate 42 are respectively connected by two sets of guide structures arranged opposite to each other. The guide structure includes a guide shaft and a guide seat slidingly arranged thereon. The first flat plate 42 and the second flat plate 43 are respectively connected to the corresponding guide seats. The first flat plate 42 is driven to move by a first telescopic cylinder vertically arranged on its lower side, and the second flat plate 43 is driven to move by a second telescopic cylinder arranged on the first flat plate 42 perpendicular to the moving direction of the movable frame 41.

[0050] Combine Figure 7 In order to facilitate the receiving structure to smoothly receive the intercooler air chamber casting 1 from the casting equipment 2, the clamping assembly includes at least two spaced-apart clamping blocks, and the upper sides of the two clamping blocks are respectively provided with upward-opening clamping grooves, and the center lines of the two clamping grooves along their arrangement directions are not parallel. That is, when the core is extracted along the axis of the intake pipe section 12 or the receiving structure transfers the casting, the intercooler air chamber product will not be easily moved under the action of the two clamping blocks.

[0051] Specifically, the two clamping blocks include a first clamping block 44 and a second clamping block 45 that respectively clamp the lower sides of the air outlet flaring section 11 and the intake pipe port section 12 of the intercooler air chamber product. The air outlet flaring section 11 and the intake pipe port section 12 respectively have a U-shaped cross-sectional shape and an annular clamping section. The clamping grooves on the first clamping block 44 and the second clamping block 45 are a rectangular groove that cooperates with the lower side of the clamping section of the air outlet flaring section 11 and a V-shaped groove that the second clamping block 45 cooperates with the lower side of the clamping section of the intake pipe port section 12, respectively.

[0052] It should be noted that the above-mentioned casting equipment 2 is a commercially available casting equipment 2, and its specific structure is not shown in the drawings. For example, Figure 2 , the upper template of the casting equipment 2 can drive the upper die mold and the intercooler air chamber casting 1 to move vertically relative to the lower die. Moreover, an ejection mechanism capable of separating the intercooler air chamber casting 1 from the upper die mold is also provided on the upper template. During use, after the upper template drives the upper die mold and the intercooler air chamber casting 1 to move vertically upward, the moving frame 41 drives the material receiving mechanism to extend into the lower side of the corresponding intercooler air chamber casting 1. Then, through the position adjustment of the ejection mechanism and the material receiving mechanism, the lower side of the intercooler air chamber casting 1 is clamped on each clamping block, and then it is transported to the cleaning unit, replacing manual transportation of the high-temperature intercooler air chamber casting 1 and improving safety.

[0053] For the cleaning unit, specifically in combination with Figure 12 and Figure 8 it is concerned that the core-pulling protrusion includes two relatively arranged first protrusions 14. The abutting part includes a positioning plate 62 that can abut against the intercooler air chamber casting 1. Moreover, a through hole 621 for one end of the core-pulling protrusion of the core to pass through is opened on the positioning plate 62. The pulling part includes two relatively arranged pulling blocks 65 and a driving machine 66 that drives them to move horizontally. Moreover, the two pulling blocks 65 can relatively expand and contract and respectively abut against one side of the two first protrusions 14 close to the abutting part.

[0054] The two relatively arranged first protrusions 14 on the core body 13 can prevent the core from being skewed and stuck due to unilateral force application, which is beneficial to the smooth extraction of the core, and a second protrusion 15 is also provided on the outer wall of the core body 13 between the two first protrusions 14.

[0055] A guide plate 67 is provided on one side of the positioning plate 62 close to the pulling part. A guide groove 671 adapted to the second protrusion 15 is horizontally provided on the guide plate 67. Moreover, a third avoidance opening 622 communicating with the through hole 621 and the guide groove 671 is provided on the positioning plate 62 corresponding to the second protrusion 15. The rotation of the core is restricted by the cooperation of the second protrusion 15 and the guide groove 671 to ensure the accuracy of the pulling direction.

[0056] Specifically, the vertical height of the movable seat 61 is adjustable, and the movable seat 61 is also provided with a mounting plate 64 arranged opposite to the positioning plate 62. The driving motor 66 is a second high-pressure oil cylinder arranged on the mounting plate 64, and its output end passes horizontally through the mounting plate 64 and is connected to the support plate 63. The support plate 63 is close to the side of the positioning plate 62 and is provided with two fixed blocks opposite to each other, and a third telescopic cylinder is provided thereon. The output end of the third telescopic cylinder is connected to a limiting shaft passing through the fixed block. The pull block 65 is provided at the end of the limiting shaft away from the third telescopic cylinder, and an inter-axial bushing is also provided between the limiting shaft and the fixed block, and the side surfaces of the two pull blocks 65 relative to each other are inclined surfaces, and the distance between the two inclined surfaces close to the positioning plate 62 is greater than the distance close to the mounting plate 64.

[0057] Combine Figures 8-10 The positioning plate 62 includes a first positioning plate 62 and a second positioning plate 62 spaced apart in an upper and lower manner. The first positioning plate 62 and the second positioning plate 62 are provided with semicircular arc openings facing each other in the middle of the opposite sides. The diameter of the semicircular arc openings is not less than the diameter of the air inlet pipe section 12 of the intercooler air chamber product, and the vertical spacing between the two positioning plates 62 is not less than the vertical dimension of the first protrusion 14, that is, the gap between the two positioning plates 62 is the through opening 621 mentioned above.

[0058] The lower end of the second positioning plate 62 is connected to the movable seat 61 , one end of the guide plate 67 is connected to the mounting plate 64 , the upper end of the first positioning plate 62 is connected to the other end of the guide plate 67 , and the third avoidance opening 622 is vertically provided on the first positioning plate 62 .

[0059] Combine Figure 4 and Figure 5 An upper pressing piece 8 is provided below the first flat plate 42 near the horizontal plate 51. The upper pressing piece 8 is driven to rise and fall by a fourth telescopic cylinder arranged vertically. The upper pressing piece 8 can be a flat plate arranged at the output end of the fourth telescopic cylinder, so that when the riser is cut off, the upper pressing piece 8 can rise to press against the lower side of the first flat plate 42, thereby assisting in clamping the intercooler air chamber casting 1.

[0060] Combine Figure 6 A receiving plate 7 capable of vertical movement is also provided laterally on one side of the movable seat 61 close to the punching mechanism 5. The receiving plate 7 is a V-shaped bending part with an opening facing upward, and the receiving plate 7 is driven to move vertically by a fifth telescopic cylinder vertically provided on one side of the movable seat 61, so as to rise and catch the core after the core is extracted to prevent the core from falling.
