[0045] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] Please refer to Figures 1 to 3 , Figure 1An isometric view of a specific embodiment of the metal mold casting production line provided by the present invention; Figure 2 A side view of a pouring line of a metal mold casting production line in a specific embodiment; Figure 3 It is a schematic end view of a metal mold casting production line in a specific embodiment.

[0047] The metal mold casting production line provided in this embodiment includes at least one pouring line and a pouring machine 200. A plurality of casting machines 100 are arranged on the pouring line. It can be understood that the plurality of casting machines 100 are arranged to form the pouring line.

[0048] Please refer to Figures 4 to 6 , Figure 4 for Figure 1 Axonometric view of the casting machine; Figure 5 for Figure 4 Side view of the casting machine; Figure 6 for Figure 4 Front view of the casting machine.

[0049] Each casting machine 100 has at least one station for installing the mold 500, which includes an upper mold base 120 for installing the upper mold 510 of the mold 500 and a lower mold base 132 for installing the lower mold 520 of the mold 500, and the lower mold base 132 is located below the upper mold base 120, wherein the lower mold base 132 can move vertically relative to the upper mold base 120 to switch between the mold opening position and the mold closing position. It can be understood that in the mold closing position, the upper mold 510 and the lower mold 520 are attached and are in a pouring state, and in the mold opening position, the upper mold 510 and the lower mold 520 are separated.

[0050] The pouring machine 200 can move along the pouring line to perform a liquid injection operation on the mold 500 in the mold closing position of the casting machine 100 .

[0051] As mentioned above, the closing or opening of the mold of the casting machine 100 can be achieved by controlling the relative movement of the lower mold base 132 and the upper mold base 120, by controlling the pouring machine 200 to move along the pouring line, and performing liquid injection operations on the mold 500 that has been closed on the casting machine 100 located on the pouring line. In this way, the casting production line can realize automatic operations of opening and closing the mold 500, and automatic liquid injection operations using the pouring machine 200. Compared with the traditional method of casting relying solely on manual labor, the labor intensity of manual labor is greatly reduced, the human influence factors are reduced, the efficiency of casting production can be improved and labor costs can be reduced, and at the same time, the consistency of the quality of casting production can be improved.

[0052] Generally speaking, in order to facilitate the movement of the pouring machine 200 along the pouring line and the subsequent conveying operations for the formed castings, the pouring line is usually provided in a straight line form, that is, a plurality of casting machines 100 are arranged in a straight line to form a pouring line. It can be understood that the casting machines 100 on the same pouring line have the same orientation. In this way, when the pouring machine 200 moves along the pouring line, it can directly perform liquid injection operations on the molds 500 installed on each casting machine 100 without considering the direction, etc.

[0053] In a specific solution, the pouring machine 200 is driven by a driving unit to move along the pouring line. Specifically, a track 600 is set on the pouring side of the pouring line. The pouring machine 200 can move along the track 600 to the pouring station of the casting machine 100 to be poured under the drive of the driving unit.

[0054] The pouring machine 200 is specifically an automatic pouring machine having a pouring control unit, and the casting machine 100 includes a casting control unit. The two are communicatively connected. The casting control unit of the casting machine 100 can control the mold closing or mold opening and other related operations of each workstation thereon, and feed back the mold closing state of the workstation thereon to the pouring control unit of the pouring machine 200. After receiving the signal that a certain workstation is in the mold closing position, the pouring control unit can feed back the signal to the driving unit, so that the driving unit drives it to move to the workstation in the mold closing position to be poured, and perform liquid injection operation on the closed mold 500.

[0055] The pouring control unit is also used to control the automatic pouring operation of the pouring machine 200. Specifically, the pouring control unit can determine the pouring position and pouring amount of the pouring port of the pouring machine 200 based on relevant detection elements such as the load sensor and visual sensor of the pouring machine 200. After the pouring is completed, the pouring completion signal can also be fed back to the casting control unit to enable the casting control unit to control the subsequent operations of the casting machine 100 after the liquid injection is completed.

[0056] It should be pointed out here that, in practical applications, the control programs of the above-mentioned control units can refer to existing control programs or be designed based on the principles of existing control programs combined with actual needs.

[0057] In the illustrated scheme, there are two pouring lines, namely the first pouring line 1A and the second pouring line 1B, which are arranged in parallel, and the casting machine 100 of the first pouring line 1A and the casting machine 100 of the second pouring line 1B are arranged in reverse, so that when the pouring machine 100 moves along the outer side of each pouring line (the side of one pouring line away from the other pouring line), the casting machines 100 on the two pouring lines can perform liquid injection operations without changing the direction. In other words, the pouring port of the casting machine 100 on the first pouring line 1A should be located on the side away from the second pouring line 1B, that is, on the outer side.

[0058] In this embodiment, a horizontal conveyor 700 is further provided below the pouring line. After the mold 500 of the casting machine 100 is injected with liquid and performs related operations (described in detail later) to form a casting, the casting can also be blanked and the formed casting is conveyed to the horizontal conveyor 700. The horizontal conveyor 700 conveys the castings formed by the casting machines 100 on the pouring line, thereby further improving the degree of automation of the casting production line.

[0059] On the basis of setting up two pouring lines, the two pouring lines can share a horizontal conveyor 700, such as Figure 3 As shown, the horizontal conveyor 700 is located below the first pouring line 1A and the second pouring line 1B, and between the first pouring line 1A and the second pouring line 1B. Obviously, the blanking direction of the casting machine 100 on the first pouring line 1A and the second pouring line 1B is toward the inside to approach one side between the two pouring lines.

[0060] As shown in the figure, each casting machine 100 on the pouring line is supported by a first supporting surface 2A, and the horizontal conveyor 700 is supported by a second supporting surface 2B. It can be understood that in order to facilitate the blanking operation of the casting machine 100, the second supporting surface 2B is lower than the first supporting surface 2A.

[0061] In practical applications, the first supporting surface 2A is usually the ground for easy layout. Thus, the second supporting surface 2B is located below the ground, which means that a groove needs to be dug downward at the corresponding position of the ground to facilitate the layout of the horizontal conveyor 700 and related components (described later).

[0062] On this basis, in order to facilitate the transportation of the castings to the desired location, a first lifting mechanism 910 is provided at one end of the horizontal conveyor 700. The castings on the horizontal conveyor 700 are lifted to the first supporting surface 2A, i.e., the ground, by the first lifting mechanism 910 to facilitate subsequent transportation, etc.

[0063] Specifically, the first lifting mechanism 910 can be an inclined scale plate conveyor, or a bucket elevator, or other mechanisms with a lifting function.

[0064] Please refer to Figures 8 to 10 , Figure 8 It is a structural schematic diagram of an upper mold of a mold in a specific embodiment; Fig. 9 It is a schematic diagram of the structure after the lower mold and the pouring cup of the mold are assembled in a specific embodiment; Fig.10 It is a schematic diagram of the structure of the pouring cup in a specific embodiment.

[0065] In this embodiment, when pouring to form a casting, a pouring port for the pouring liquid is formed by using a pouring cup 400. Specifically, the pouring cup 400 is installed between the upper mold 510 and the lower mold 520. When the pouring machine 200 is pouring, the molten metal is poured into the pouring port 411 of the pouring cup 400, and flows into each cavity through the pouring channel inside the pouring cup 400 and the outlet 430 connected to the pouring channel.

[0066] On this basis, the casting production line is also provided with a core placing robot 300, which is used to place the pouring cup 400 into the mold 500 installed at each station on the casting machine 100. The core placing robot 300 can move along the pouring line. Specifically, the core placing robot 300 can move along the aforementioned track 600, that is, share the track 600 with the pouring machine 200.

[0067] The core setting robot 300 is also connected to the casting control unit of the casting machine 100 for communication so as to feed back the placement status of the pouring cup 400 to the casting control unit, so as to facilitate the control of the casting machine 100 for subsequent operations.

[0068] In this way, the degree of automation of the casting production line can be further improved.

[0069] Please refer to Fig.12 , Fig.12 It is a structural schematic diagram of the core setting robot in a specific embodiment.

[0070] In this embodiment, the core setting robot 300 includes a mobile platform 310 , a robot body 330 and a visual sensor 340 . The mobile platform 310 can cooperate with the track 600 to facilitate the movement of the core setting robot 300 along the track 600 .

[0071] During actual operation, when the lower core robot 300 moves to the workstation where the pouring cup 400 needs to be placed, the robot body 300 grabs the pouring cup 400 and determines the placement position of the pouring cup 400 based on its visual sensor 340 to accurately place the pouring cup 400 on the lower mold 520 of the corresponding workstation.

[0072] In addition, a storage area 320 may be provided on the mobile platform 310 for storing the pouring cup 400 .

[0073] In actual configuration, the visual sensor 340 may also be replaced by other sensors that can locate the placement position of the pouring cup 400 .

[0074] Below Figures 8 to 10 The illustrated solution exemplarily illustrates the structure of the mold 500 and the pouring cup 400. In actual application, the mold 500 and the corresponding pouring cup 400 are also configured differently according to different casting structures.

[0075] In this embodiment, the mold 500 has multiple cavities to facilitate the one-time pouring of molten metal to cast multiple castings. The figure shows an example in which each mold 500 has 5 cavities. In actual settings, the number of cavities can be more than 5, and of course, it can also be 2 to 4 cavities.

[0076] The upper mold 510 has five upper cavities 511 , and the lower mold 520 has five lower cavities 512 , which are located in corresponding positions so that after the upper mold 510 and the lower mold 520 are molded together, the upper cavity 511 and the corresponding lower cavity 512 form one cavity.

[0077] To facilitate the arrangement of the pouring cup 400 and to allow the pouring liquid to flow into each cavity simultaneously during pouring, each cavity is evenly distributed along a circle.

[0078] The pouring cup 400 is placed at the center of each cavity. The number of the openings 430 of the pouring cup 400 is the same as the number of the cavities, and the positions correspond one to one after assembly.

[0079] Specifically, the lower mold 520 has an installation position for installing the pouring cup 400, and the upper mold 510 has a through hole portion 512 for inserting the pouring cup. When in use, the core lowering robot 300 can be used to place the pouring cup 400 in the installation position of the lower mold 520. During the process of closing the lower mold 520 and the upper mold 510, the pouring cup 400 is inserted into the through hole portion 512 of the upper mold 510. After closing the mold, the pouring gate 411 of the pouring cup 400 is exposed from the surface of the upper mold 510 to facilitate the subsequent liquid injection operation of the pouring machine 200.

[0080] In a specific solution, for the convenience of manufacturing, the pouring cup 400 is a split structure, including an upper pouring portion 410 and a lower pouring portion 420, and the two can be fixed by snapping together to prevent misalignment from affecting pouring.

[0081] In the illustrated scheme, a portion of the outlet 430 of the pouring cup 400 is formed below the upper pouring portion 410, and the other portion is formed above the lower pouring portion 420. After the upper pouring portion 410 and the lower pouring portion 420 are engaged, the upper and lower portions of the outlet 430 correspond to each other to form a connecting port connecting the internal pouring channel of the pouring cup 400 and the cavity, so that the molten metal flowing in from the pouring gate 411 can flow out from each outlet 430 to the corresponding cavity.

[0082] In the specific solution, the pouring cup 400 is a sandy pouring cup. After the casting is completed and the mold is opened, the pouring cup 400 is dropped together with the casting. The pouring cup 400 is affected by the high-temperature molten metal and will adhere to the casting. It is also easy to disperse and may be dispersed into fragments during the dropping process. In other words, the pouring cup 400 is a disposable item.

[0083] After the material is dropped, the waste sand formed by the pouring cup 400 moves with the horizontal conveyor 700 together with the casting.

[0084] On this basis, a vibrating sand-falling machine 800 is also provided at one end of the horizontal conveyor 700 where the first lifting mechanism 910 is arranged. The vibrating sand-falling machine 800 is located between the horizontal conveyor 700 and the first lifting mechanism 910. The castings with waste sand conveyed by the horizontal conveyor 700 are first conveyed to the vibrating sand-falling machine 800, and the sand-falling operation is performed on the vibrating sand-falling machine 800 so that the waste sand adhered to the castings can be separated from the castings. The separated castings can slide onto the first lifting mechanism 910 along the dropping hopper of the vibrating sand-falling machine 800.

[0085] The casting production line is also provided with a second lifting mechanism 920 cooperating with the vibrating sand shaker 800 to transport the separated waste sand to the first supporting surface 2A.

[0086] The second lifting mechanism 920 may specifically be a belt conveyor with an inclination angle, or a bucket elevator, etc.

[0087] In actual settings, the horizontal conveyor 700, the first lifting mechanism 910 and the second lifting mechanism 920 also have independent control modules respectively, and each control module can exchange data with the aforementioned control units via Ethernet to realize the automated operation of the entire production line.

[0088] In this embodiment, a cooling system is also provided, and after the pouring machine 200 completes the injection, a cooling operation is performed to obtain a solidified casting. A smoke spraying mechanism 160 can also be provided to spray carbon deposits on the surface of the cavity of the mold 500 to form a carbon deposit layer before casting, so as to facilitate demoulding.

[0089] The smoke spraying mechanism 160 can also be realized by automatic control, so as to avoid manually applying the isolation protective layer on the cavity surface of the mold 500 to facilitate demoulding.

[0090] The cooling system needs to be combined with the relevant structural functions of the mold 500, specifically, Figure 8 and Fig. 9 As shown, cooling channels are formed inside the upper mold 510 and the lower mold 520 , and the cooling medium inlet 531 and the cooling medium outlet 532 of the cooling channel are formed on the peripheral wall of the upper mold 510 and the peripheral wall of the lower mold 520 .

[0091] The cooling system includes a cooling medium source and a pipeline connected between the cooling medium source and the cooling medium inlet 531 and the cooling medium outlet 532 of the upper mold 510, and a pipeline connected between the cooling medium source and the cooling medium inlet 531 and the cooling medium outlet 532 of the lower mold 520. A flow valve group is arranged on each pipeline. The cooling passage is opened when cooling is required and the cooling flow rate can be controlled by the control of the cooling control unit. The cooling control unit can also record the cooling time to ensure the solidification state of the casting.

[0092] During the specific setting, the area of ​​the cooling channel of the upper mold 510 corresponds to each upper mold cavity 511, so that the cooling medium flowing into the cooling channel of the upper mold 510 can cool all the upper mold cavities 511, and the area of ​​the cooling channel of the lower mold 520 also corresponds to each lower mold cavity 521, so that the cooling medium flowing into the cooling channel of the lower mold 520 can cool all the lower mold cavities 521, thereby ensuring the cooling effect of the casting in each cavity.

[0093] The cooling medium may specifically be water, compressed air or others.

[0094] In this solution, part of the cooling system pipelines and the smoke spraying mechanism 160 are integrated into the aforementioned casting machine 100 to facilitate related operations on the mold 500 at each station on the casting machine 100. Of course, in actual settings, it can also be set relatively independently from the casting machine 100.

[0095] The casting machine 100 integrated with the cooling pipeline and the smoke injection mechanism 160 is described in detail below.

[0096] like Figures 4 to 6 As shown, in this embodiment, the casting machine 100 includes a frame 110, and the frame 110 includes a base 111, at least two front support columns 112 located on one side of the base 110, and at least two rear support columns 113 located on the other side of the base 110. Figure 4 and Figure 5 In the orientation shown, the front refers to the side close to the left, and correspondingly, the back refers to the side close to the right.

[0097] In the specific configuration, the number of the front support columns 112 and the rear support columns 113 are the same, and the positions correspond one to one, and a work station is formed between two adjacent front support columns 112 and the corresponding two rear support columns 113 .

[0098] Each workstation is provided with an upper mold base 120 and a lower mold base 132. The upper mold base 120 is used to install the upper mold 510 of the mold 500, and the lower mold base 132 is used to install the lower mold 520 of the mold 500. The lower mold base 132 can move vertically relative to the upper mold base 120 to switch between the mold opening position and the mold closing position.

[0099] For a casting machine 100, more than two workstations can be set on its frame 110, and each workstation can be arranged in a straight line to facilitate the subsequent casting lines to be formed in a straight line, so as to facilitate the control of the movement and injection operation of the casting machine 200; at the same time, it can also improve the compactness of the structure.

[0100] In the illustrated scheme, there are four corresponding support columns at the front and rear of the casting machine 100, so that one casting machine 100 has three workstations.

[0101] In actual application, the number of workstations of the casting machine 100 is set according to needs.

[0102] In this embodiment, in order to reduce the driving structure, the position of the upper die base 120 is relatively fixed, and the lower die base 132 can move vertically close to or away from the upper die base 120. In actual setting, if there is no other need, of course, the lower die base 132 can also be relatively fixed, and the upper die base 120 can move vertically close to or away from the lower die base 132.

[0103] Specifically, the upper mold base 120 is fixed to the upper end of the frame 110 relative to the base 111, and can be specifically fixedly connected to the front support column 112 and the rear support column 113 at corresponding positions.

[0104] It should be noted that the structure of the upper mold base 120 should be such that the upper surface of the upper mold 510 is exposed after installation, so that after assembly, the pouring gate 411 of the pouring cup 400 can be exposed to facilitate the pouring operation of the pouring machine 200.

[0105] In this embodiment, since the upper mold base 120 is relatively fixed to the frame 110, in actual setting, the upper mold base 120 corresponding to each workstation can be an integrally formed structure, for example, an integrated upper mold frame is provided, and the upper mold frame has upper mold bases 120 corresponding to the number of workstations.

[0106] In this embodiment, the lower die base 132 can move vertically. In order to make the actions of each workstation relatively independent, the lower die base 132 corresponding to each workstation is independently provided.

[0107] Specifically, the lower mold base 132 is vertically slidably connected to the front support column 112 and the rear support column of the corresponding workstation.

[0108] In this embodiment, the casting machine 100 is also provided with a flipping mechanism, which can drive the lower mold 520 to flip so that the casting located in the lower mold 520 can be automatically dropped after the casting is completed and the mold is opened, so as to improve the degree of automation; on the casting production line, the casting can be dropped to the horizontal conveyor 700.

[0109] In order to enable the casting to fall smoothly and accurately from the casting machine 100 to the horizontal conveyor 700, the casting machine 100 is also provided with a blanking component 170. The blanking component 170 is tilted, and its upper receiving end is located below the lower die seat 132, and its tilting direction is related to the direction of blanking.

[0110] like Figure 5 As shown, in this solution, the upper end of the blanking component 170 is located in front of the front support column 112 to ensure that the casting can enter the blanking component 170 when it falls. The whole is tilted rearward and downward relative to the frame 110, so that the casting can automatically fall along the tilted direction of the blanking component 170 by gravity.

[0111] In the casting production line, there are Figure 3 As shown in the figure, when the two pouring lines share a horizontal conveyor 700, the casting machine 100 on the first pouring line 1A and the casting machine 100 on the second pouring line 1B are arranged back to back, that is, the front support column 112 of the casting machine 100 is located on the outside of the corresponding pouring line, so that the pouring machine 200 can inject liquid into the mold 500 of each station on the periphery. After the blanking component 170 is arranged as above, the blanking component 170 makes the blanking direction of the casting to the inside of the pouring line, that is, between the two pouring lines, so that the two pouring lines can share a horizontal conveyor 700.

[0112] It can be understood that in actual settings, if it does not affect the injection operation of the pouring machine 200 and does not involve the problem of two pouring lines sharing the horizontal conveyor 700, the inclination direction of the blanking part 170 can be set to other directions as needed, such as lateral inclination or forward inclination, etc., depending on specific needs.

[0113] In a specific solution, the blanking component 170 is a trough-shaped blanking hopper structure with ribs on both sides to prevent the casting from escaping from the blanking component 170. Specifically, the inclination of the blanking component 170 near its discharge end is set to be smaller to provide a buffer for the casting so that it can be smoothly dropped to the horizontal conveyor 700.

[0114] In this embodiment, in order to realize the vertical movement and flipping action of the lower mold 520, a lower mold frame 130 is specifically arranged at each workstation of the casting machine 100. The lower mold frame 130 includes a lower mold base 132 and a lower flip seat 133. The lower flip seat 133 is rotatably connected to the lower mold base 132. During installation, the lower mold 520 is specifically installed on the lower flip seat 133. The lower mold base 132 can move vertically, driving the lower flip seat 133 and the lower mold 520 installed thereon to move vertically together. The lower flip seat 133 can also rotate relative to the lower mold base 132 so that the lower mold 520 installed thereon can be flipped to drop the casting to the blanking part 170.

[0115] Specifically, a slider 131 is fixedly provided on the lower mold base 132, and a guide rail 1131 extending vertically is installed on the rear support column 113. The lower mold base 132 slides with the guide rail 1131 through the slider 131. The cooperation between the slider 131 and the guide rail 1131 can provide guidance for the vertical movement of the lower mold base 132, ensuring the directionality of the movement of the lower mold 520 driven by the lower mold base 132.

[0116] In actual configuration, the lower die base 132 and the front support column 112 may also be provided with sliding blocks and guide rails that cooperate with each other, specifically so that the lower die base 132 can move vertically and smoothly.

[0117] The casting machine 100 also includes a first driving member for driving the lower die base 132 to move vertically upward or downward. The first driving member can be specifically configured as a mold clamping cylinder 140, and the lower die base 132 is driven to move vertically upward or downward by the extension and retraction of the mold clamping cylinder 140.

[0118] Specifically, the cylinder body of the mold closing cylinder 140 is fixedly connected to the base 111 of the frame 110, and the telescopic rod is fixedly connected to the lower mold base 132. When the telescopic rod of the mold closing cylinder 140 is extended, it drives the lower mold base 132 to move vertically upward, and when the telescopic rod of the mold closing cylinder 140 is retracted, it drives the lower mold base 132 to move vertically downward.

[0119] A limit switch may be provided on the upper die base 120. When the mold clamping cylinder 140 drives the lower die base 132 to move to the position where the lower die 520 and the upper die 510 are clamped, the limit switch may feedback a command to stop the mold clamping cylinder 140 to avoid excessive movement and collision damage to related parts. Of course, in actual settings, the telescopic rod of the mold clamping cylinder 140 may be fully extended to correspond to the clamping position of the upper die 510 and the lower die 520. In this way, the setting of the limit switch may be omitted.

[0120] The casting machine 100 further includes a second driving member for driving the lower turning seat 133 to rotate relative to the lower die seat 132. It can be understood that the second driving member and the lower turning seat 133 constitute the aforementioned turning mechanism.

[0121] Specifically, the lower flip seat 133 and the lower mold seat 132 can be rotatably connected via a rotating shaft 1331, and the rotation centerline thereof is parallel to the horizontal direction and to the arrangement direction of the front support column 112. When flipping, the lower flip seat 133 rotates downward toward the direction of the front support column 112, driving the lower membrane 520 to rotate together, so that the lower mold cavity 521 is flipped from an opening facing upward to an opening facing downward, so that the casting formed therein can fall to the blanking component 170 below under the action of gravity.

[0122] The second driving member is specifically a flip cylinder 150, the fixed end of the flip cylinder 150 is hinged to the lower mold frame 130, and the telescopic end is hinged to the lower flip seat 133. The telescopic end of the flip cylinder 150 drives the lower flip seat 133 to flip around its rotation axis 1331.

[0123] In the illustrated scheme, the fixed end of the flip cylinder 150 is specifically hinged to the lower end of the mounting seat 134 (described below) of the lower mold frame 130, and the telescopic end is hinged to the lower end of the lower flip seat 133, and is configured such that: when the telescopic end of the flip cylinder 150 is extended, the lower mold 520 mounted on the lower flip seat 133 is in a state where it can be molded with the upper mold 510, and when the telescopic end of the flip cylinder 150 is retracted, the lower flip seat 133 drives the lower mold 520 to flip to a blanking position where blanking can be performed. In practice, the specific configuration of the flip cylinder 150 can also be other.

[0124] In this embodiment, the frame 110 of the casting machine 100 is also equipped with related hydraulic pipelines connected to the mold clamping cylinder 140 and the flip cylinder 150 and a hydraulic valve group for controlling the movement of each cylinder, such as Figure 4 As shown, a mounting plate 114 can be fixedly connected to the top of the rear side of the frame 110 (i.e., the side where the rear support column 113 is located) for installing these pipelines and hydraulic valve groups. Similarly, the mounting plate 114 can also be installed with part of the cooling medium pipeline 180 related to the aforementioned cooling system to make the structure more compact.

[0125] In this embodiment, a detection switch 190 may also be provided on the upper die holder 120. After casting is completed and the mold is opened, the detection switch 190 is used to detect whether there is a casting retained on the upper die 510, so as not to affect the subsequent casting blanking and the pouring of the next cycle. In practical applications, if there is a casting retained on the upper die 510, the detection switch 190 may feedback a signal to the casting control unit to issue an alarm signal to remind the operator.

[0126] It can be understood that the hydraulic valve group that controls the action of each cylinder and the aforementioned limit switch and detection switch 190 can be communicated with the casting control unit of the casting machine 100 to perform corresponding actions according to the received instructions.

[0127] In practical applications, the first driving member and the second driving member may not be in the form of a cylinder, for example, they may be a gas cylinder or other driving members.

[0128] In this embodiment, the aforementioned smoke spraying mechanism 160 is specifically installed on the lower mold frame 130 and can move with the lower mold frame 130 so as to be adjusted to a suitable position, so as to simultaneously spray carbon deposits into the lower mold 520 on the lower mold frame 130 and the upper mold 510 on the upper mold base 120.

[0129] Of course, in actual setting, the positions of the smoke spraying mechanism 160 and the frame 110 can also be relatively fixed, so that the mold clamping cylinder 140 is required to drive the lower mold 520 to move to a suitable position to facilitate the smoke spraying mechanism 160 to operate on the upper mold 510 and the lower mold 520 at the same time.

[0130] Specifically, the lower mold frame 130 also includes a mounting seat 134 fixed to the lower mold base 132. The mounting seat 134 is mainly located on the rear side of the rear support column 113. The smoke injection mechanism 160 is installed on the mounting seat 134 so as not to affect the operation of other components of the casting machine 100 when the carbon injection operation is not performed.

[0131] Please refer to Fig.11 and Fig.11a , Fig.11 It is a structural schematic diagram of the smoke spraying mechanism in a specific embodiment; Fig.11a for Fig.11 A partial enlarged view of area C in the middle.

[0132] In this embodiment, the smoke ejection mechanism 160 includes a driving component 161 , a mounting platform 162 , an air ring 163 and an ignition needle 164 .

[0133] The air ring 163 and the ignition needle 164 are mounted on the mounting platform 162 . The air ring 163 has an air inlet 1631 for the combustion medium to flow in. The air ring 163 is provided with a plurality of air holes 1632 along its circumference.

[0134] The driving component 161 is used to drive the mounting platform 162 to move so that the gas ring 163 is switched between an ignition position between the upper mold 510 and the lower mold 520 and a non-ignition position between the upper mold 510 and the lower mold 520 .

[0135] The ignition needle 164 can ignite the combustion medium at each air hole 1632 to form a carbon deposition layer that plays an isolating role in each upper mold cavity 511 of the upper mold 510 and each lower mold cavity 521 of the lower mold 520, which is convenient for subsequent demolding. Obviously, the ignition operation of the ignition needle 164 is performed when the gas ring 163 is at the ignition position between the upper mold 510 and the lower mold 520.

[0136] For ease of arrangement, Fig.11 As shown, each air hole 1632 of the air ring 163 is opened on its upward surface, and the ignition needle 164 is specifically located above the air ring 163. In order to be able to ignite the combustion medium at each air hole 1632 at the same time, the ignition needle 164 is preferably located in the middle area of ​​the air ring 163.

[0137] During specific installation, the mounting platform 162 is installed on the mounting seat 134 of the lower mold frame 130 through the support frame 165, and the mounting platform 162 is slidably connected to the support frame 165. The sliding direction of the mounting platform 162 can be set to be parallel to the front and rear direction of the frame 110, that is, the mounting platform 162 can move toward the front side of the frame 110 relative to the support frame 165 to drive the air ring 163 and the ignition needle 164 thereon to move to between the upper mold 510 and the lower mold 520, or move toward the rear side of the frame 110 relative to the support frame 165 to withdraw from between the upper mold 510 and the lower mold 520 to avoid affecting subsequent operations.

[0138] Specifically, a slider portion 1621 may be provided on the mounting platform 162 , and a slide rail 166 is installed on the support frame 165 . The slider portion 1621 cooperates with the slide rail 166 to guide the sliding of the mounting platform 162 .

[0139] In this embodiment, the driving component 161 can specifically be a telescopic cylinder or an electric push rod, etc. The movable end of the driving component 161 is connected to the mounting platform 162, and the fixed end thereof can be mounted on the mounting seat 134 of the lower mold frame 130 through the mounting frame 167.

[0140] In a specific solution, the combustion medium used by the smoke spraying mechanism 160 is acetylene, and the combustion of acetylene in the air is incomplete combustion, so a carbon deposit layer can be formed in the cavity of the mold 500. In practice, the combustion medium can also be other gases that can produce carbon deposits.

[0141] In the specific setting, the number of the air holes 1632 of the air ring 163 is consistent with the number of the cavities of the mold 500, and when in the ignition position, corresponds to the position of each cavity to ensure the carbon deposition layer formed on the wall surface of each cavity.

[0142] like Fig.11 As shown, the air ring 163 is specifically formed by bending a tube, one end of which is sealed, and the other end forms an air inlet 1631, which is connected to a gas source with a combustion medium through a pipeline. A switch valve can be set on the pipeline. The smoke spraying mechanism 160 can also be provided with a smoke spraying control unit to control the action of the driving component 161, the opening and closing of the switch valve, and the ignition operation of the ignition needle 164.

[0143] The smoke injection control unit can specifically communicate with the casting control unit to control the actions of the relevant components of the smoke injection mechanism 160 according to the feedback instructions of the casting control unit. For example, when the casting control unit feeds back that the upper mold 510 and the lower mold 520 are in the smoke injection position, a start signal can be fed back to the smoke injection control unit. After receiving the start signal, the smoke injection control unit sequentially controls the driving component 161 to drive the mounting platform 162 to move to the ignition position, opens the switch valve to allow the combustion medium to flow into the gas ring 163, and then ignites the ignition needle 164. After the subsequent smoke injection is completed, each component is sequentially controlled to move in the opposite direction.

[0144] It should be noted here that the smoke injection position and the ignition position mentioned here are actually the same position, that is, at this position, the ignition needle 164 can ignite the combustion medium to cause incomplete combustion and generate carbon deposits that are sprayed onto the surface of the cavity.

[0145] Please refer to Figures 7a to 7e , respectively showing the structural schematic diagram of the casting machine in the mold closing position, mold opening position, flipping position, smoke spraying position and smoke spraying state in a specific embodiment.

[0146] like Figure 7a As shown, at this time, the casting machine 100 is in the mold closing position, that is, the mold closing cylinder 140 drives the lower mold base 132 to move upward until the lower mold 520 installed thereon is fitted with the upper mold 510 installed on the upper mold base 120. It can be understood that at this time, the pouring cup 400 has been placed in the mold 500. At this position, the pouring machine 200 can perform liquid injection operations.

[0147] like Figure 7b As shown in FIG. 1 , at this time, the casting machine 100 is in the mold opening position, that is, the mold closing cylinder 140 drives the lower mold base 132 to move downward to a state where the lower mold 520 is separated from the upper mold 510. Specifically, the telescopic rod of the mold closing cylinder 140 is completely retracted. At this time, if the liquid injection and cooling are completed and the casting has solidified, then the lower flip seat 133 with the lower mold 520 installed can be flipped to the position as shown in FIG. 1 through the control of the flip cylinder 150. Figure 7c The casting and the pouring cup 400 are turned over to the blanking part 170. At this time, before the liquid is injected, the lower mold 520 can be driven to move upward to fit with the upper mold 510 by the control of the mold closing cylinder 140. Figure 7a The mold clamping position.

[0148] like Figure 7d As shown, at this time, the casting machine 100 is in the smoke spraying position, that is, the relative position between the lower mold 520 and the upper mold 510 is adjusted by the mold clamping cylinder 140, so that the relative positions between the smoke spraying mechanism 160 and the upper mold cavity 511 of the upper mold 510 and the lower mold cavity 521 of the lower mold 520 are all appropriate, so as to ensure the effect of spraying the carbon deposition layer. Figure 7d In the embodiment, the upper mold 510 and the lower mold 520 are in the smoke spraying position, but the gas ring 163 and the ignition needle 164 of the smoke spraying mechanism 160 have not yet moved to the ignition position. Figure 7e As shown, at this time, the driving component 161 of the smoke spraying mechanism 160 has driven the mounting platform 162 to the ignition position, and the ignition needle 164 has been ignited and is in a state of spraying the carbon deposit layer.
