[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Please refer to Figures 1 to 6e , Figure 1 It is an isometric view of a specific embodiment of the casting machine provided by the present invention; Figure 2 for Figure 1 Side view of the casting machine; Figure 3 for Figure 1 Front view of the casting machine; Figure 4 It is a structural schematic diagram of the smoke spraying mechanism in a specific embodiment; Figure 5 for Figure 4 A partial enlarged view of the middle C area; Figures 6a to 6e The structural schematic diagrams of the casting machine in the specific embodiment are respectively shown in the mold closing position, mold opening position, flipping position, smoke spraying position and smoke spraying state.

[0036] The casting machine 100 provided in this embodiment includes at least one workstation for installing the mold 500, and the workstation includes an upper mold base 120 and a lower mold frame 130. The upper mold base 120 is used to install the upper mold 510 of the mold 500, and the lower mold frame 130 is used to install the lower mold 520 of the mold 500. The workstation also includes a first driving member, and the first driving member is used to drive the upper mold base 120 and the lower mold frame 130 to move relative to each other to switch between a mold opening position and a mold closing position. In the mold opening position, the upper mold 510 and the lower mold 520 are in contact with each other and are in a state where casting can be performed. In the mold opening position, the upper mold 510 and the lower mold 520 are separated.

[0037] In practice, in order to facilitate control and arrangement of related components, the direction of relative movement of the upper mold base 120 and the lower mold base 130 is parallel to the vertical direction.

[0038] As described above, the casting machine 100 can be used for the casting production of castings. During production, the closing or opening of the mold 500 can be achieved by controlling the relative movement of the lower mold frame 130 and the upper mold base 120 through the first driving member. In this way, the automatic operation of opening and closing the mold 500 can be achieved. Compared with the traditional method of relying on manual mold opening and closing, the labor intensity of manual labor is greatly reduced, the human influence factors are reduced, the efficiency of casting production can be improved and the labor cost can be reduced, and at the same time, the consistency of casting production quality can be improved.

[0039] In addition, the casting machine 100 also provides conditions for full automation of casting production. For example, in practical applications, multiple casting machines 100 can be arranged in the same direction to form a pouring line, and an automatic pouring machine can be used to move along a track to perform liquid injection operations on the mold 500 in the closing position at each workstation of the casting machine 100.

[0040] In this embodiment, the casting machine 100 includes a frame 110, which includes a base 111, at least two front support columns 112 located at the front side of the base 110, and at least two rear support columns 113 located at the rear side of the base 110. Figure 1 and Figure 2 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.

[0041] In the specific setting, adjacent front support columns 112 are arranged at a certain distance, the number of front support columns 112 and 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.

[0042] Each workstation is provided with an upper mold base 120 and a lower mold frame 130. The upper mold base 120 is used to install the upper mold 510 of the mold 500, and the lower mold frame 130 is used to install the lower mold 520 of the mold 500. The lower mold frame 130 can move vertically relative to the upper mold base 120 to switch between the mold opening position and the mold closing position.

[0043] For a casting machine 100, more than two workstations can be set on its frame 110, and the workstations can be arranged in a straight line to facilitate the subsequent formation of the pouring line so that the pouring stations are in a straight line, which is convenient for controlling the movement and injection operation of the pouring machine; at the same time, it can also improve the compactness of the structure.

[0044] It is understandable that in actual application, the casting machine 100 does not have to form a pouring line, and a single casting machine 100 can also be used in conjunction with an automatic pouring machine.

[0045] 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.

[0046] In actual application, the number of workstations of the casting machine 100 is set according to needs.

[0047] In this embodiment, in order to reduce the driving structure, the position of the upper mold base 120 is relatively fixed, and the lower mold frame 130 can move vertically close to or away from the upper mold base 120. In actual setting, if there is no other need, of course, the lower mold frame 130 can also be relatively fixed, and the upper mold base 120 can move vertically close to or away from the lower mold frame 130.

[0048] 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.

[0049] It should be pointed out 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 gate of the mold 500 is exposed, which is convenient for subsequent liquid injection operations.

[0050] 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.

[0051] In this embodiment, the lower mold frame 130 can move vertically. In order to make the actions of each workstation relatively independent, the lower mold frame 130 corresponding to each workstation is independently provided.

[0052] In this embodiment, the lower mold frame 130 includes a lower mold base 132 and a lower flip seat 133. The lower flip seat 133 is used to install the lower mold 520. The lower flip seat 133 is rotatably connected to the lower mold base 132, and also includes a second driving member. The second driving member is used to drive the lower flip seat 133 to rotate relative to the lower mold base 132 to drive the lower mold 520 to flip to the blanking position. When in the blanking position, the casting formed in the lower mold 520 can fall under the action of gravity.

[0053] Specifically, on the basis of setting a plurality of workstations, the rotation centerline of the lower flip seat 133 relative to the lower mold seat 132 is parallel to the arrangement direction of the plurality of workstations.

[0054] Specifically, the lower flip seat 133 can be rotatably connected to the lower mold seat 132 via a rotating shaft 1331 .

[0055] This can further improve the automation of the casting machine 100. After the casting is completed, there is no need to manually remove the casting. It also provides conditions for full automation of casting. For example, in actual applications, when forming the aforementioned pouring line, a horizontal conveying mechanism parallel to the pouring line can be set. The horizontal conveying mechanism is located below the casting machine 100 on the pouring line to receive the castings dropped from the casting machine 100, so as to facilitate the unified delivery of the castings to a designated place.

[0056] On this basis, in order to enable the casting formed by the casting machine 100 to fall smoothly to the desired position, the casting machine 100 also includes a blanking component 170 located below the lower mold frame 130.

[0057] Specifically, the blanking component 170 is arranged to be tilted downward, and its upper receiving end 170a is located below the lower mold base 132. Obviously, the receiving end 170a of the blanking component 170 refers to the end close to the lower mold 520, and the discharging end 170b refers to the end relatively far away from the receiving end 170a. The casting is separated from one end of the blanking component 170 after being guided by the blanking component 170.

[0058] In actual configuration, the discharge end 170b of the blanking component 170 may be docked with other containers for storing castings as required, in addition to docking with the aforementioned horizontal conveying mechanism.

[0059] As shown in the figure, the blanking component 170 specifically includes a bottom wall portion 171 and side wall portions 172 fixed to both sides of the bottom wall portion 171. It can be understood that the blanking component 170 is roughly a U-shaped structure in cross section, and the two side wall portions 172 can prevent the falling casting from escaping from the blanking component 170.

[0060] In the illustrated scheme, 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. In this way, the pouring end is relatively located on the front side of the frame 110, and the discharge end of the formed casting is relatively located on the rear side of the frame 110. The two do not interfere with each other, which is convenient for forming a casting production line together with the automatic pouring machine and horizontal conveying mechanism mentioned above.

[0061] Specifically, a baffle 173 fixed to the bottom wall 171 and the side walls 172 is provided at the receiving end 170a of the falling component 170. The baffle 173 is used to prevent the falling casting from escaping from the falling component 170 from the receiving end 170a, so that it can fall obliquely along the bottom wall 171 to the discharging end 170b.

[0062] Specifically, the bottom wall portion 171 of the blanking component 170 includes a first inclined section 1711 relatively close to the material receiving end 170a and a second inclined section 1712 relatively far from the material receiving end 170a, and the angle between the first inclined section 1711 and the horizontal plane is greater than the angle between the second inclined section 1712 and the horizontal plane. In this way, the inclination of the portion of the blanking component 170 close to its discharge end 170b is set to be smaller, so as to provide a buffer for the casting so that it can be blanked smoothly.

[0063] In this embodiment, the lower mold base 132 of the lower mold frame 130 is specifically slidably connected to the rear support column 113 of the frame 110 so as to slide vertically under the drive of the first driving member.

[0064] 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.

[0065] 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 stably.

[0066] In this embodiment, the first driving member is specifically a mold clamping cylinder 140 , and the lower mold base 132 is driven to move vertically upward or vertically downward by the extension and retraction of the mold clamping cylinder 140 .

[0067] 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.

[0068] In this embodiment, a limit switch can be set on the upper mold base 120. When the mold closing cylinder 140 drives the lower mold base 132 to move to the position where the lower mold 520 and the upper mold 510 are closed, the limit switch can feedback instructions to the casting control unit of the casting machine 100 to stop the movement of the mold closing cylinder 140 to avoid excessive movement and collision damage to related components.

[0069] In this embodiment, 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.

[0070] 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 is driven to rotate downward toward the direction of the front support column 132, and the lower mold 520 is driven to flip to a blanking position where blanking can be performed, that is, the opening of the lower mold cavity of the lower mold 520 is facing downward. In practice, the specific configuration of the flip cylinder 150 can also be other.

[0071] 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 1 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 used to install part of the cooling medium pipeline 180 related to the cooling system to make the structure more compact.

[0072] Here, the cooling system refers to a system for cooling the casting after pouring. Specifically, a cooling channel is provided inside the mold 500. The cooling medium source of the cooling system can be connected to the cooling channel of the mold 500 through a cooling pipeline, so that the cooling medium flows through the cavity to cool the casting.

[0073] In another embodiment, a detection switch 190 can be installed on the upper mold base 120. After the casting is completed and the lower mold frame 130 drives the lower mold 520 to move to the mold opening position, the detection switch 190 can send a retention signal to the casting control unit when it detects that the upper mold 510 has a casting retained, so that the casting control unit sends an alarm signal. In practical applications, after the mold is opened, the upper mold 510 and the lower mold 520 are separated, but the casting may be retained on the upper mold 510, which not only affects the subsequent blanking and the pouring of the next cycle, but also poses a safety hazard. The setting of the detection switch 190 can avoid this problem. When it is detected that a casting is retained in the upper mold 510, a signal can be fed back to the casting control unit, so that the casting control unit sends an alarm signal to remind the operator to handle it in time.

[0074] 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.

[0075] 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.

[0076] In this embodiment, the casting machine 100 is further provided with a smoke spraying mechanism 160 to spray carbon deposits onto the surface of the cavity of the mold 500 to form a carbon deposit layer before the first casting, so as to facilitate demoulding.

[0077] 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.

[0078] In this embodiment, the 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, and can 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.

[0079] 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.

[0080] 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.

[0081] 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 .

[0082] 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.

[0083] 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 .

[0084] The ignition needle 164 can ignite the combustion medium at each air hole 1632 to form a carbon deposition layer in each upper mold cavity of the upper mold 510 and each lower mold cavity of the lower mold 520 to play an isolating role, 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.

[0085] For ease of arrangement, Figure 4 and Figure 5As 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.

[0086] 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.

[0087] 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 .

[0088] 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.

[0089] 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.

[0090] 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.

[0091] like Figure 4 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.

[0092] 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.

[0093] 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.

[0094] Please refer to Figures 6a to 6e ,like Figure 6a 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 up until the lower mold 520 installed thereon is in contact with the upper mold 510 installed on the upper mold base 120. At this position, liquid injection operation can be performed.

[0095] like Figure 6b 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 6c The casting and the pouring cup (if the pouring cup is used to form the pouring gate) are dropped 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 6a The mold clamping position.

[0096] like Figure 6d 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 of the upper mold 510 and the lower mold cavity of the lower mold 520 are appropriate, so as to ensure the effect of spraying the carbon deposition layer. Figure 6d 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 6e 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.
