[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] The structure of a thin - walled slider core - pulling forming mold for a sealing piece provided by the present utility model is as Figure 1 And Figure 4 Shown, including a lower template 1, an upper lower mold core 2 is arranged above the lower template 1, and a buffer mechanism 7 is arranged between the lower mold core 2 and the lower template 1. The buffer mechanism 7 is used for the buffering work when the lower mold core 2 is pressed down. The buffer mechanism 7 includes a guide post 71, a buffer spring 72, an ejector cylinder 73 and a side support plate 74. Four groups of guide posts 71 are provided, and the four groups of guide posts 71 are fixedly connected to the surface of the lower template 1. An ejector cylinder 73 is arranged on the surface of the lower template 1 and inside the guide posts 71. The ejector cylinder 73 facilitates the demolding work. A buffer spring 72 is sleeved on the surface of the guide post 71, and the top end of the buffer spring 72 is fixedly connected to the surface of the lower mold core 2; a side support plate 74 is arranged outside the guide post 71, and the side support plate 74 is used for the support work when the lower mold core 2 is pressed down.

[0024] During implementation, during the mold - closing process, the upper mold core 4 will be pressed down under the action of pressure to contact the lower mold core 2. This process is limited by the cooperation of the limit sleeve 41 and the limit post 21. After the upper mold core 4 contacts the lower mold core 2, the lower mold core 2 will move downward, and then the buffer spring 72 on the surface of the guide post 71 is used for buffering and unloading force, so that the lower mold core 2 contacts the side support plate 74, avoiding the occurrence of rigid collision during mold - closing and causing damage to the mold.

[0025] Furthermore, as Figure 2 And Figure 3As shown in the figure, an upper template 3 is arranged above the lower template 1, and a top mold core 4 is fixed to the bottom end of the upper template 3. The top mold core 4 cooperates with the bottom mold core 2. A limit sleeve 41 is installed at the bottom end of the top mold core 4, and a limit post 21 is fixed to the top end of the bottom mold core 2. When the top mold core 4 and the bottom mold core 2 are closed, the limit sleeve 41 and the limit post 21 cooperate to limit the position. A mold clamping mechanism 6 is arranged between the bottom mold core 2 and the top mold core 4. The mold clamping mechanism 6 is used for mold clamping work. The mold clamping mechanism 6 includes a mold clamping block 61, a lower mold base 62 and an upper mold base 63. The mold clamping block 61 is arranged on one side of the bottom mold core 2 and the top mold core 4. The bottom end of the mold clamping block 61 is provided with the lower mold base 62, and one end of the lower mold base 62 penetrates through the mold clamping block 61 and is threadedly connected to the surface of the bottom mold core 2. The top end of the mold clamping block 61 is provided with the upper mold base 63, and one end of the upper mold base 63 penetrates through the mold clamping block 61 and is threadedly connected to the surface of the top mold core 4.

[0026] During implementation, by rotating the lower mold base 62 and the upper mold base 63 to fix them to the bottom mold core 2 and the top mold core 4 respectively, and through the cooperation of the mold clamping block 61 with the lower mold base 62 and the upper mold base 63, the bottom mold core 2 and the top mold core 4 are tightly clamped to prevent mold opening.

[0027] Furthermore, as Figure 2 and Figure 3 shown in the figure, core-pulling mechanisms 5 are arranged on both the left and right sides of the surface of the bottom mold core 2. The core-pulling mechanism 5 is composed of a support frame 51, a core-pulling cylinder 52, a core-pulling block 53 and a connecting block 54. The support frame 51 is arranged on the surface of the bottom mold core 2. Connecting blocks 54 are fixed to both inner walls of the support frame 51 by bolts, and the surface of the connecting block 54 is fixedly connected to the surface of the bottom mold core 2. The core-pulling cylinder 52 is fixed to the surface of the support frame 51, and a core-pulling block 53 is installed at one end of the core-pulling cylinder 52. The core-pulling block 53 cooperates with the bottom mold core 2 and the top mold core 4 for core-pulling work.

[0028] During implementation, the core-pulling cylinder 52 drives the core-pulling block 53 to retract through the support of the connecting block 54 and the support frame 51. After retraction, the mold is ejected by the ejector cylinder 73, which improves the convenience of mold ejection, reduces the labor intensity during the demolding process, and thus improves the work efficiency.

[0029] Working principle: During use, first, the top mold core 4 and the bottom mold core 2 are closed. During the closing process, buffering is carried out through the buffering mechanism 7. During the closing process, the top mold core 4 will be pressed down under the action of pressure to contact the bottom mold core 2. This process is limited by the cooperation of the limit sleeve 41 and the limit post 21. After the top mold core 4 contacts the bottom mold core 2, the bottom mold core 2 will move downward, and then the buffering spring 72 on the surface of the guide post 71 is used for buffering and unloading force, so that the bottom mold core 2 contacts the side support plate 74, avoiding the phenomenon of rigid collision during mold closing that may cause damage to the mold.

[0030] After the mold is closed, the mold clamping mechanism 6 is used for mold clamping. When the mold clamping mechanism 6 is implemented, the lower mold base 62 and the upper mold base 63 are rotated to be fixed to the lower mold core 2 and the upper mold core 4 respectively, and the lower mold core 2 and the upper mold core 4 are locked by the mold clamping block 61 in cooperation with the lower mold base 62 and the upper mold base 63 to avoid mold opening.

[0031] Subsequently, the molten material enters between the lower mold core 2 and the upper mold core 4 through the pouring port in the center of the upper template 3 for casting. After molding, the mold clamping mechanism 6 is operated to open the upper mold core 4 and the lower mold core 2. Subsequently, the core pulling mechanism 5 is used for core pulling. When the core pulling mechanism 5 is implemented, the core pulling cylinder 52 drives the core pulling block 53 to retract by the support of the connecting block 54 and the support frame 51. After retraction, the mold is ejected by the ejecting cylinder 73, which improves the convenience of mold ejection and reduces the labor intensity during the mold ejection process, thereby improving the work efficiency.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
