Technical Field

[0001] This utility model belongs to the field of mold production technology, and in particular relates to a casting piston mold trial molding machine. Background Technology

[0002] In casting production, the development of molds and the replacement of old molds are also massive processes. It requires a dedicated mold production workshop with complete processing equipment and production capacity to meet the mold needs of the piston casting workshop.

[0003] However, problems still exist. Due to the large number of molds produced, the qualification of a mold needs to be verified by casting piston blanks in the foundry and conducting full-size inspections on the cast piston blanks. The usual manual mold testing can no longer keep up with the needs of production. Moreover, manual mold testing is time-consuming and labor-intensive, not only inefficient but also posing certain safety hazards. It also requires extensive experience from the mold testing personnel. These phenomena undoubtedly restrict the qualified entry of molds into the warehouse. Summary of the Invention

[0012] Furthermore, the fixing component includes:

[0013] An arc-shaped frame is slidably mounted on the worktable.

[0014] The support column has one end fixedly installed in the recess of the bow-shaped frame, and the other end faces the opening and closing mold;

[0015] A hydraulic cylinder is fixedly mounted on the workbench and is used to drive the bow-shaped frame to move left and right. The piston rod end of the hydraulic cylinder is fixedly connected to the other end of the bow-shaped frame.

[0016] The fixing components are symmetrically arranged in two sets, which are located on the left and right sides of the clamping table respectively. The bottom of the opening and closing mold is fixed by the cooperation of the step and the movable plate. The outer molds on the left and right sides of the opening and closing mold are pushed and fixed by the support columns of the two sets of fixing components.

[0017] Furthermore, the mold-opening component includes:

[0018] The telescopic plate is movable forward and backward at the front end of the bow-shaped frame;

[0020] A drive assembly, used to drive the telescopic plate to move left and right;

[0021] The two halves of the opening and closing mold have bolt heads at both ends. After the support column of the bow-shaped frame presses against the outer mold of the opening and closing mold, the protruding structure is used to hook the bolt heads and pull one of the outer molds outward after the cast blank cools.

[0022] Furthermore, the driving component includes:

[0023] The drive cylinder is fixedly mounted at the front end of the bow-shaped frame;

[0024] The lever is fixedly mounted at the front end of the bow-shaped frame;

[0025] A guide shaft is movably mounted at the front end of the bow-shaped frame, and the rear end of the telescopic plate is fixedly connected to the rear end of the guide shaft.

[0026] One end of the lever is rotatably connected to the piston rod end of the driving cylinder, and the other end of the lever is rotatably connected to the rear end of the guide shaft.

[0027] Furthermore, it also includes:

[0028] The adjusting bolt has a spiral set at the rear end of the bow-shaped frame and is oriented towards the rear side of the opening and closing mold.

[0029] Furthermore, it also includes:

[0035] 3. It realizes automated mold opening, replacing the traditional manual hammering mold opening method. The mold opening process is smooth and impact-free, reducing the risk of mold damage and extending the service life of the mold.

[0036] 4. The lever amplification principle is used to realize the large stroke movement of the telescopic plate, which meets the displacement requirements of the outer mold fixing and mold opening, while ensuring the stability and accuracy of the action, avoiding rigid impact caused by direct drive, and pushing the opening and closing mold through the guide shaft to avoid the plate-like structure of the telescopic plate being pushed and bent by force.

[0037] 5. By setting adjustment bolts, the mold opening and closing can be fixed in multiple directions through the cooperation of the guide shaft and adjustment bolts, as well as the cooperation of the support column and the movable plate. This effectively improves the mold closing accuracy, prevents molten liquid from leaking from the mold gap during the casting process, and ensures the forming quality of the piston blank.

[0038] 6. By setting the clearance groove, the movement of the support column is avoided, interference is prevented during fixing, the coordinated action of the mold bottom fixing and the outer mold fixing is ensured, and the overall structural compatibility and operation smoothness of the equipment are improved.

It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1

[0049] This embodiment provides a casting piston mold trial molding machine, including a worktable 1, and further comprising:

[0050] A clamping table 2 is fixedly mounted on the workbench 1, and a step 16 is formed by a protrusion at the upper end of the clamping table 2.

[0051] The opening and closing mold 3 is set on the clamping table 2, and one side of the opening and closing mold 3 abuts against the end face of the step 16;

[0052] Movable plate 4, one end of which is rotatably connected to workbench 1;

[0053] The swing cylinder 5 has one end rotatably connected to the worktable 1, and its piston rod end rotatably connected to the middle section of the movable plate 4.

[0054] A fixing component is set on the worktable 1 and is used to fix the opening and closing mold 3 for a secondary purpose;

[0055] The mold opening assembly is set on the workbench 1 and is used to open the mold 3 after the cast blank has cooled.

[0056] The other end of the movable plate 4 abuts against the other side of the opening and closing mold 3.

[0057] In this technical solution, during actual use, the mold 3 that needs to be tested is placed on the clamping table 2, so that one side of it abuts against the end face of the step 16 to form an initial positioning.

[0058] Next, the swing cylinder 5 is started to work. The piston rod extends and retracts, causing the movable plate 4 to rotate around the rotating end. The other end of the movable plate 4 abuts against the other side of the opening and closing mold 3, and cooperates with the step 16 to clamp and fix the two sides of the opening and closing mold 3.

[0059] This structural design enables rapid and stable positioning of the mold 3, achieving a quick clamping effect compared to the traditional manual fixing method. At the same time, it effectively prevents the mold 3 from shifting during the casting process. Example 2

[0060] This embodiment provides a casting piston mold trial molding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] Furthermore, the fixing component includes:

[0062] The bow-shaped frame 6 is slidably mounted on the worktable 1;

[0063] The support column 7 has one end fixedly installed in the recess of the bow-shaped frame 6, and the other end faces the opening and closing mold 3;

[0064] A hydraulic cylinder 8 is fixedly mounted on the workbench 1 and is used to drive the bow-shaped frame 6 to move left and right. The piston rod end of the hydraulic cylinder 8 is fixedly connected to the other end of the bow-shaped frame 6.

[0065] The fixing components are symmetrically arranged in two sets, which are located on the left and right sides of the clamping platform 2 respectively. The bottom of the opening and closing mold 3 is fixed by the cooperation of the step 16 and the movable plate 4. The outer molds on the left and right sides of the opening and closing mold 3 are pushed and fixed by the support columns 7 of the two sets of fixing components.

[0066] In this technical solution, during actual use, the mold 3 that needs to be tested is placed on the clamping table 2, so that one side of it abuts against the end face of the step 16 to form an initial positioning.

[0067] Next, the swing cylinder 5 is started to work. The piston rod extends and retracts, causing the movable plate 4 to rotate around the rotating end. The other end of the movable plate 4 abuts against the other side of the opening and closing mold 3, and cooperates with the step 16 to clamp and fix the bottom of the opening and closing mold 3.

[0068] When the hydraulic cylinder 8 is started, the piston rod extends and drives the bow-shaped frame 6 to slide along the worktable 1. The bow-shaped frame 6 is slidably mounted on the worktable 1 by means of the cooperation of the slider and the guide rail (the slider and the guide rail are existing technologies and will not be described in detail here).

[0069] Two sets of symmetrical bow-shaped frames 6 move synchronously, and the support columns 7 on them gradually approach and push the outer molds on the left and right sides of the opening and closing mold 3, thereby fixing the outer molds with the support columns 7.

[0070] With this structural design, both sides of the mold bottom and both sides of the outer mold of the mold 3 can be fixed during the trial molding. Compared with the traditional single-point fixing, the outer mold is subjected to more uniform force and the mold closing accuracy is higher. At the same time, it effectively reduces the leakage of molten liquid during casting and improves the forming quality of the blank. Example 3

[0071] This embodiment provides a casting piston mold trial molding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] Furthermore, the mold-opening component includes:

[0073] The telescopic plate 9 is movable at the front end of the bow-shaped frame 6;

[0074] The groove plate 10 is fixedly installed at the rear end of the bow-shaped frame 6. The front end of the telescopic plate 9 and the upper end of the groove plate 10 are both bent to form a protruding structure 18.

[0075] A drive assembly, which is used to drive the telescopic plate 9 to move left and right;

[0076] The two halves of the outer mold of the opening and closing mold 3 have bolt heads 17 at both ends. After the support column 7 of the bow frame 6 presses against the outer mold of the opening and closing mold 3, the protruding structure 18 is used to hook the bolt heads 17 and pull one of the outer molds outward after the cast blank cools.

[0077] In this technical solution, during actual use, the mold 3 that needs to be tested is placed on the clamping table 2, so that one side of it abuts against the end face of the step 16 to form an initial positioning.

[0078] Then, the hydraulic cylinder 8 is started, the piston rod extends, and the bow-shaped frame 6 slides along the worktable 1. The two sets of symmetrical bow-shaped frames 6 move synchronously. When the front and rear ends of the bow-shaped frame 6 move to the point where the telescopic plate 9 and the groove plate 10 correspond to the bolt heads 17 on the front and rear sides of the outer mold of the opening and closing mold 3, the drive assembly is started. The drive assembly drives the telescopic plate 9 to move towards the front side of the outer mold. After moving to the point of contact with the front end of the outer mold, it pushes the mold bottom and the outer mold to move backward, so that the bolt heads 17 at the rear of the outer mold move backward into the protruding structure 18 of the groove plate 10. At the same time, the bolt heads 17 at the front end of the outer mold are located in the protruding structure 18 of the telescopic plate 9.

[0079] Next, the swing cylinder 5 is started to work. The piston rod extends and retracts, causing the movable plate 4 to rotate around the rotating end. The other end of the movable plate 4 abuts against the other side of the opening and closing mold 3, and cooperates with the step 16 to clamp and fix the bottom of the opening and closing mold 3.

[0080] Then, the support column 7 on the hydraulic cylinder 8 gradually approaches and pushes the outer molds on the left and right sides of the opening and closing mold 3, thereby fixing the support column 7 to the outer mold and completing the overall fixing of the outer mold.

[0081] When the mold is opened, the front protrusion of the telescopic plate 9 hooks the front bolt head 17 of the outer mold, while the upper protrusion of the groove plate 10 jams the rear bolt head 17 of the outer mold. Through the symmetrically arranged fixing components, the bow-shaped frame 6 can hook the bolt head 17 through the telescopic plate 9 and the protrusion structure 18 of the groove plate 10 during the return stroke, thereby driving one half of the outer mold to move outward.

[0082] This structural design enables automated mold opening, replacing the traditional manual hammering method. The mold opening process is smooth and impact-free, reducing the risk of mold damage and extending the mold's service life. Example 4

[0083] This embodiment provides a casting piston mold trial molding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0084] Furthermore, the driving component includes:

[0085] The drive cylinder 11 is fixedly mounted at the front end of the bow-shaped frame 6;

[0086] Lever 12 is fixedly mounted at the front end of the bow-shaped frame 6;

[0087] The guide shaft 13 is movably disposed at the front end of the bow-shaped frame 6, and the rear end of the telescopic plate 9 is fixedly connected to the rear end of the guide shaft 13.

[0088] One end of the lever 12 is rotatably connected to the piston rod end of the drive cylinder 11, and the other end of the lever 12 is rotatably connected to the rear end of the guide shaft 13.

[0089] In this technical solution, during actual use, the mold 3 that needs to be tested is placed on the clamping table 2, so that one side of it abuts against the end face of the step 16 to form an initial positioning.

[0090] Then the hydraulic cylinder 8 is started, the piston rod extends, and the bow frame 6 slides along the worktable 1. The two sets of symmetrical bow frames 6 move synchronously. The front and rear ends of the bow frame 6 move until the telescopic plate 9 and the groove plate 10 correspond to the bolt heads 17 on the front and rear sides of the outer mold of the opening and closing mold 3, respectively.

[0091] When the drive cylinder 11 is activated, the piston rod of the drive cylinder 11 extends or retracts, converting linear motion into the forward and backward sliding of the guide shaft 13 through the lever 12 mechanism. The lever arm ratio of the lever 12 is designed to be 1:2, and the moving distance of the guide shaft 13 is twice the extension or retraction amount of the drive cylinder 11, thereby achieving efficient driving of the guide shaft 13 and the telescopic plate 9.

[0092] The guide shaft 13 moves backward, pushing the opening and closing mold 3 and the mold bottom to the other side by abutting, thereby causing the bolt head 17 at the rear of the outer mold to move backward into the protrusion structure 18 of the groove plate 10, while the bolt head 17 at the front end of the outer mold is located in the protrusion structure 18 of the telescopic plate 9.

[0093] Next, the swing cylinder 5 is started to work. The piston rod extends and retracts, causing the movable plate 4 to rotate around the rotating end. The other end of the movable plate 4 abuts against the other side of the opening and closing mold 3, and cooperates with the step 16 to clamp and fix the bottom of the opening and closing mold 3.

[0094] Then, the support column 7 on the hydraulic cylinder 8 gradually approaches and pushes the outer molds on the left and right sides of the opening and closing mold 3, thereby fixing the support column 7 to the outer mold and completing the overall fixing of the outer mold.

[0095] Next, the piston blank is cast. After the blank cools, the bow frame 6 is driven back by the hydraulic cylinder 8. The bow frame 6 drives the groove plate 10 and the telescopic plate 9 to reset. At the same time, the groove plate 10 and the telescopic plate 9 hook the bolt head 17 of the mold through the protruding structure 18, thereby pulling the two halves of the mold apart and opening the mold.

[0096] Through this structural design, the large stroke movement of the telescopic plate 9 is realized by using the lever 12 amplification principle, which meets the displacement requirements of the outer mold fixing and mold opening, while ensuring the stability and accuracy of the action, avoiding rigid impact caused by direct drive, and at the same time, the guide shaft 13 pushes the opening and closing mold 3 to avoid the plate-like structure of the telescopic plate 9 being pushed and bent by force. Example 5

[0097] This embodiment provides a casting piston mold trial molding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0098] Furthermore, the adjusting bolt 14 is spirally positioned at the rear end of the bow-shaped frame 6 and facing the rear side of the opening and closing mold 3.

[0099] In this technical solution, after the outer mold is fixed, the drive shaft can continue to move forward to abut against the front end of the outer mold. Then, by turning the adjusting bolt 14, the screw end of the adjusting bolt 14 can be pressed against the rear end of the outer mold.

[0100] Through this structural design, by setting the adjusting bolt 14, the opening and closing mold 3 can be fixed in multiple directions through the cooperation of the guide shaft 13 and the adjusting bolt 14, as well as the cooperation of the support column 7 and the movable plate 4. This effectively improves the mold closing accuracy, avoids the leakage of molten liquid from the mold gap during the casting process, and ensures the forming quality of the piston blank. Example 6

[0101] This embodiment provides a casting piston mold trial molding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0102] Furthermore, it also includes:

[0103] The movable plate 4 has a through groove 15, the plane of which is lower than that of the support column 7, and the width of the groove 15 is greater than that of the support column 7.

[0104] Through this structural design, the avoidance groove 15 is set to avoid the movement of the support column 7, avoid interference during fixing, ensure the coordinated action of the mold bottom fixing and the outer mold fixing, and improve the overall structural compatibility and operation smoothness of the equipment. Example 7

[0105] This embodiment provides a casting piston mold trial molding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0106] Furthermore, the connecting surface between the step 16 and the clamping platform 2 is an oblique surface that faces inward concavity towards the step 16.

[0107] This structural design ensures that when the mold is placed, the right-angled part of the bottom of the mold 3 can be within the beveled surface, thus avoiding contact errors.
