Description

Technical Field

[0001] The utility model belongs to the technical field of sealing, in particular to a mold sealing structure. Background Art

[0002] In the prior art, corresponding slots for the sealing rings need to be opened on both the upper and lower molds of the mold. However, these slots are straight-up, so that after being used for a long time, when an air gun is used for cleaning, the sealing ring is easily blown out of the slot, which requires repeated manual installation, which is very troublesome. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a mold sealing structure which has the characteristic of reducing the falling off of the sealing ring.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A mold sealing structure comprises an upper mold, a lower mold and a sealing strip, wherein the upper mold has a mounting groove, and the mounting groove gradually becomes smaller from a side away from the lower mold toward a side close to the lower mold; the lower mold has a card slot, and the sealing strip has a mounting portion adapted to the mounting groove and a card-in portion adapted to the card slot, and the mounting portion is installed in the mounting groove.

[0006] In the above mold sealing structure, the upper mold has a first contact surface, the slot has a first limit surface and a second limit surface, there is a gap between the first limit surface and the second limit surface, and the gap gradually decreases from the side away from the lower mold to the side close to the lower mold.

[0007] In the above mold sealing structure, the first limiting surface and the second limiting surface are symmetrically arranged.

[0008] In the above mold sealing structure, the installation groove of the upper mold has a protrusion, and the sealing strip is provided with a receiving groove corresponding to the protrusion on the side close to the upper mold. The receiving groove is located between the first limiting surface and the second limiting surface, and the protrusion is inserted into the receiving groove.

[0009] In the above mold sealing structure, the cross section of the clamping groove is square, and the shape of the clamping portion corresponds to the clamping groove.

[0010] Compared with the prior art, this application has the following advantages:

[0011] In the present application, the design of the gradually smaller installation groove allows the installation portion of the sealing strip to be installed more tightly therein, thereby improving the reliability and stability of the seal. Compared with the traditional straight-up card slot, this structure can effectively prevent the sealing strip from being easily blown off or falling out of the installation groove during operations such as cleaning, thereby reducing the trouble of repeated manual installation. Since the accidental falling off of the sealing strip is reduced, the time and energy spent on reinstallation are saved, thereby improving the overall work efficiency.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figures 1 to 3 As shown, a mold sealing structure includes an upper mold 2, a lower mold 3 and a sealing strip 4, the upper mold 2 has a mounting groove 21, and the mounting groove 21 gradually becomes smaller from the side away from the lower mold 3 to the side close to the lower mold 3; the lower mold 3 has a card slot 31, and the sealing strip 4 has a mounting portion 41 adapted to the mounting groove 21 and a card-in portion 42 adapted to the card slot 31, and the mounting portion 41 is installed in the mounting groove 21.

[0021] In the present application, the gradually smaller design of the mounting groove 21 allows the mounting portion 41 of the sealing strip 4 to be more tightly mounted therein, thereby improving the reliability and stability of the seal. Compared with the traditional straight-up slot 31, this structure can effectively prevent the sealing strip 4 from being easily blown off or detached from the mounting groove 21 during operations such as cleaning, thereby reducing the trouble of repeated manual installation. Since the accidental falling off of the sealing strip 4 is reduced, the time and energy spent on reinstallation are saved, thereby improving the overall work efficiency.

[0022] Specifically, the upper mold 2 has a first contact surface 22, the slot 31 has a first limiting surface 311 and a second limiting surface 312, there is a gap between the first limiting surface 311 and the second limiting surface 312, and the gap gradually decreases from the side away from the lower mold 3 to the side close to the lower mold 3.

[0023] The first limiting surface 311 and the second limiting surface 312 as well as the gradually decreasing interval design can better limit the mounting portion 41 of the sealing strip 4, making its position more stable after installation and less prone to shaking or displacement, while also ensuring a continuous and stable sealing effect.

[0024] Specifically, the first limiting surface 311 and the second limiting surface 312 are symmetrically arranged.

[0025] This design enables the first limiting surface 311 and the second limiting surface 312 to form a better clamping effect, thereby preventing the sealing ring from falling out.

[0026] Specifically, the mounting groove 21 of the upper mold 2 has a protrusion 32 , and the sealing strip 4 has a receiving groove 43 corresponding to the protrusion on the side close to the upper mold 2 . The receiving groove 43 is located between the first limiting surface 311 and the second limiting surface 312 , and the protrusion 32 is inserted into the receiving groove 43 .

[0027] This design allows the large head portion of the mounting portion 41 of the sealing strip 4 to be inserted more easily from the small opening of the card slot 31. After insertion, as the width of the mounting slot 21 gradually increases, the sealing strip 4 is gradually reset until the protrusion 32 is inserted into the accommodating slot 43 of the sealing strip 4. After that, the large head portion of the mounting portion 41 of the sealing strip 4 is more difficult to retract toward the middle, thereby further reducing the occurrence of the sealing strip 4 being blown out.

[0028] Specifically, the cross section of the slot 31 is square, and the shape of the snap-in portion 42 corresponds to the slot 31 .

[0029] The shape of the slot 31 on the lower mold 3 allows the snap-in portion 42 of the sealing strip 4 to be snapped into the slot 31 after the upper mold 2 and the lower mold 3 are closed, and when the upper mold 2 and the lower mold 3 are separated thereafter, the installation portion 41 of the sealing strip 4 will not fall out of the installation slot 21.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
