The first mold 2 and the second mold 3 are fitted together through the fitting mechanism 4. The mounting frame 1 is provided with a demoulding mechanism 5 for automatically demoulding the tensioner chain stop block 0.

[0036] like Figure 1 and Figure 3 As shown, the laminating mechanism 4 includes a driving motor 41, a fixed plate 42, a bidirectional screw rod 43, a movable frame 44, a connecting frame 45, a first pressure spring 46, a double-axis motor 47 and a cam 48.

The left and right parts of the bidirectional screw rod 43 are both connected to the movable frame 44 by threads, and the movable frame 44 contacts the mounting frame 1 when it moves inward, and the connecting frames 45 are connected to the outer sides of the first mold 2 and the second mold 3. The connecting frames 45 are slidably connected to the movable frame 44 on the same side, and the connecting frames 45 are connected to the movable frame 44 on the same side with two front and rear first pressure springs 46, and the upper part of the right movable frame 44 is connected to the double-axis motor 47, and the front and rear output shafts of the double-axis motor 47 are connected to cams 48, and the cams 48 contact the connecting frame 45 on the right.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, the demoulding mechanism 5 includes a two-way electric push rod 51, a limit frame 52, a first support frame 53, a top frame 54 and a second pressure spring 55. The middle part of the mounting frame 1 is connected to two left and right two-way electric push rods 51. The telescopic ends of the front and rear parts of the two-way electric push rod 51 are connected to the limit frames 52. The outer sides of the upper and lower parts of the first mold 2 and the second mold 3 are connected to the front and rear first support frames 53. The first support frames 53 are all C-shaped. The upper and lower parts of the first mold 2 and the second mold 3 are slidably connected to the front and rear top frames 54. The top frames 54 are slidably connected to the adjacent first support frames 53. The top frames 54 are connected to the adjacent first support frames 53 with second pressure springs 55.

[0038] When the tensioner chain stopper block 0 needs to be cast, the device can be used to make the mounting frame 1 contact with the ground, and then start the driving motor 41, and the bidirectional screw rod 43 is driven to rotate by the driving motor 41. Under the action of the thread, the moving frame 44 is moved at the same time, and then the connecting frame 45 is driven to move, so that the first mold 2 and the second mold 3 are moved and fitted at the same time, and the first support frame 53 and the top frame 54 are moved at the same time. After the fitting is completed, the molten metal is poured between the first mold 2 and the second mold 3. After the appropriate molten metal is poured, the double-axis motor 47 is started, and the cam 48 is driven by the double-axis motor 47 to rotate and connect with the right part. The connecting frame 45 contacts the first mold 2 and the second mold 3, so that the connecting frame 45 moves, and then the first mold 2 and the second mold 3 move left and right, and the first pressure spring 46 is deformed, so that the molten metal between the first mold 2 and the second mold 3 is shaken, so that the molten metal is evenly distributed in the first mold 2 and the second mold 3, so that the molten metal can be shaken after the molten metal is poured into the mold, and the flow of the molten metal is accelerated, so that the molten metal is filled in the mold faster and more evenly, the formation of pores is reduced, and the quality of casting is improved. Then the dual-axis motor 47 is turned off, the first pressure spring 46 is restored, and the connecting frame 45 and the first mold 2 and the second mold 3 move left and right. The first mold 2 and the second mold 3 are used to cool and shape the molten metal to form the tensioner chain stopper block 0. After cooling and shaping, the bidirectional electric push rod 51 is started, and the limit frame 52 is driven to move inward at the same time by the bidirectional electric push rod 51, so that the limit frame 52 contacts the top frame 54, and then the bidirectional electric push rod 51 is closed, and then the driving motor 41 is controlled to operate in the reverse direction, so that the bidirectional screw rod 43 rotates in the reverse direction, and the moving frame 44 is moved in the reverse direction at the same time under the action of the thread, thereby driving the connecting frame 45 to move in the reverse direction, so that the first mold 2 and the second mold 3 are moved in the reverse direction and separated at the same time, thereby driving the first supporting frame 53 Moving along the top frame 54, the second pressure spring 55 is squeezed, and the first support frame 53 is all C-shaped, and then the tensioner chain stop block 0 is automatically pushed out for demoulding, so that it can be automatically demoulded after the molten metal is formed. The operation is simple, manpower is saved, and the production efficiency of the tensioner chain stop block 0 is improved. It is easy to use. After cooling, hold the tensioner chain stop block 0 by hand, control the two-way electric push rod 51 to operate in the reverse direction, so that the limit frame 52 moves in the reverse direction and disengages from the top frame 54, the second pressure spring 55 rebounds, and the top frame 54 moves to reset, and then the tensioner chain stop block 0 can be taken out, and then the above operation is repeated until the casting of the tensioner chain stop block 0 is completed.

[0039] like Figure 1 , Figure 6 and Figure 7As shown, it also includes an anti-drop mechanism 6, which includes a support plate 61, a sleeve 62, a slide bar 63, a top block 64 and a third pressure spring 65. The upper middle part of the mounting frame 1 is connected to the front and rear support plates 61, and the upper parts of the support plates 61 are connected to the sleeves 62. The upper sides of the front and rear parts of the mounting frame 1 are also connected to the sleeves 62. The sleeves 62 are slidably connected to the slide bars 63, and the lower sides of the upper slide bars 63 are connected to the top blocks 64. The upper sides of the lower slide bars 63 are also connected to the top blocks 64. The top blocks 64 are in contact with the first mold 2 and the second mold 3, and the slide bars 63 are connected to the third pressure springs 65 between the adjacent sleeves 62.

[0040] When the first mold 2 and the second mold 3 move to fit together, the first mold 2 and the second mold 3 will contact with the top block 64, causing the top block 64 to move, thereby driving the slide bar 63 to move along the sleeve 62, and the third pressure spring 65 is squeezed. When the molten metal is formed and the first mold 2 and the second mold 3 move and separate, the first mold 2 and the second mold 3 will separate from the top block 64, the third pressure spring 65 rebounds, and the top block 64 and the slide bar 63 move in the opposite direction to reset, so that the top block 64 contacts with the tensioner chain stop block 0 for clamping, so that the tensioner chain stop block 0 can be clamped after automatic demolding to prevent the tensioner chain stop block 0 from falling and reduce damage to the tensioner chain stop block 0, and then the tensioner chain stop block 0 can be removed.

[0041] like Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a locking mechanism 7, which includes a guide frame 71, a sliding frame 72, a handle 73 and a locking block 74.

The upper and lower parts of the handle 73 are connected to the locking blocks 74, and the locking blocks 74 are in contact with the first mold 2 and the second mold 3.

[0042] Before the first mold 2 and the second mold 3 move to fit together, the handle 73 is pulled by hand to move along the sliding frame 72, so that the blocking block 74 moves. After the first mold 2 and the second mold 3 are fitted together, the handle 73 is pushed in the opposite direction by hand to move the blocking block 74 to move in the opposite direction and contact the first mold 2 and the second mold 3, thereby clamping the first mold 2 and the second mold 3. When the first mold 2 and the second mold 3 move left and right, the handle 73 and the blocking block 74 will also be driven to move left and right, thereby driving the sliding frame 72 to move along the guide frame 71. The sliding frames 72 are all X-shaped, so that the first mold 2 and the second mold 3 can be clamped without affecting the left and right shaking of the first mold 2 and the second mold 3, thereby preventing the molten metal from flowing out, making the first mold 2 and the second mold 3 fit more closely, and improving the stability of use. When demolding is required, the handle 73 is pulled by hand to move, thereby driving the blocking block 74 to move and disengage from the first mold 2 and the second mold 3.

[0043] like Figure 1 and Fig.10 As shown, it also includes a knocking mechanism 8, which includes a second support frame 81, a rotating frame 82 and a torsion spring 83. The upper and lower parts of the connecting frame 45 are connected to the second support frame 81, and the second support frame 81 is rotatably connected to the rotating frame 82. The two rotating frames 82 on the right are in contact with the first mold 2, and the two rotating frames 82 on the left are in contact with the second mold 3. The rotating frames 82 are in contact with the moving frame 44 on the same side, and the rotating frames 82 are connected to the adjacent second support frames 81 with two front and rear torsion springs 83.

[0044] When the cam 48 rotates to move the connecting frame 45 left and right, the rotating frame 82 will rotate along the second supporting frame 81, the torsion spring 83 will be deformed and then restored, and the second supporting frame 81 will rotate and reset, thereby knocking the first mold 2 and the second mold 3. The knocking can be performed during the shaking of the first mold 2 and the second mold 3, which promotes gas escape, further reduces the formation of pores, and improves the production quality of the tensioner chain stop block 0.

[0045] like Figure 1 and Fig.11 As shown, a sealing mechanism 9 is also included, and the sealing mechanism 9 includes a fixing member 91, a feeding hopper 92, a guide plate 93, a blocking block 94 and a fourth pressure spring 95. The fixing member 91 is connected to the right side of the upper part of the first mold 2, and a feeding hopper 92 is slidably connected to the fixing member 91. The diameter of the upper part of the feeding hopper 92 is larger than that of the lower part, which is convenient for material discharge. The outer sides of the upper parts of the first mold 2 and the second mold 3 are connected to two front and rear guide plates 93, and blocking blocks 94 are slidably connected between two adjacent guide plates 93. The blocking blocks 94 are in contact with the feeding hopper 92, and fourth pressure springs 95 are connected between the guide plates 93 and the adjacent blocking blocks 94.

[0046] When it is necessary to pour the molten metal into the first mold 2 and the second mold 3, the feeding hopper 92 is pushed by hand to move along the fixing part 91 to contact the first mold 2 and the second mold 3, so that the blocking block 94 is simultaneously moved and opened along the guide plate 93, and the fourth pressure spring 95 is squeezed, and then the molten metal is poured into the feeding hopper 92. The diameter of the upper part of the feeding hopper 92 is larger than the diameter of the lower part, which is convenient for feeding, so that the molten metal flows into the first mold 2 and the second mold 3 along the feeding hopper 92. After pouring the appropriate molten metal, the feeding hopper 92 is pulled in the opposite direction by hand to reset, so that the feeding hopper 92 is separated from the first mold 2 and the second mold 3, the fourth pressure spring 95 rebounds, and the blocking block 94 moves and resets, and then the upper part of the first mold 2 and the second mold 3 is sealed, so that the hole can be sealed after the molten metal is poured in, to prevent the molten metal from flying out when the first mold 2 and the second mold 3 are shaken, to facilitate the pouring of the molten metal, and to improve the safety of use.
