[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The features of the terms "first" and "second" in the specification and claims of the utility model may explicitly or implicitly include one or more of the features. In the description of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0024] Combine the following Figure 1-Figure 3 The utility model describes a glue pouring mold.

[0025] like Figure 1 and Figure 2As shown, in an embodiment of the utility model, the glue-filling mold includes: a mold 10 and a fixture 20. The mold 10 is provided with a cavity 103, and the cavity 103 is used to set the sealed component 30. The mold 10 is also provided with a glue injection hole 101 and a vent hole 102. The glue injection hole 101 is used to inject sealant into the cavity 103, and the vent hole 102 is used to exhaust gas. The glue injection hole 101 and the vent hole 102 are respectively arranged at both ends of the mold 10, and the glue injection hole 101 and the vent hole 102 are both connected to the cavity 103. The mold 10 can be opened and closed, wherein the mold 10 is a plastic mold. The fixture 20 is sleeved on the outside of the mold 10 to close the mold 10.

[0026] Specifically, the mold 10 can be opened and closed. When the mold 10 is in the open state, the part to be sealed 30 can be set in the cavity 103 of the mold 10, and then the mold 10 is closed. After the mold 10 is closed, the center line of the mold 10 is collinear with the center line of the part to be sealed 30. The clamp 20 is sleeved on the outside of the mold 10 to fix the mold 10, and the clamp 20 is used to connect with the glue injection equipment. Then, the sealant is injected into the cavity 103 through the glue injection hole 101, and the sealant surrounds the outside of the part to be sealed 30 to perform glue injection and sealing on the part to be sealed 30. During the glue injection process, the gas is discharged from the exhaust hole 102.

[0027] Furthermore, in the prior art, the inner wall of the mold 10 is coated with Teflon material, so that the sealant will not adhere to the inner wall of the mold 10. Since the coating thickness is difficult to control, some inner walls of the mold 10 are coated thicker and some are coated thinner, resulting in different thicknesses of the sealing layer formed after the sealant 30 is sealed, affecting the quality of the sealant 30.

[0028] In this embodiment, the mold 10 is a plastic mold. The surface viscosity of the plastic mold is poor and it is not easy to adhere to the sealant. Therefore, the mold 10 can be put into use after it is manufactured. There is no need to coat the inner wall of the mold 10, which solves the problem of easy adhesion during injection of glue. At the same time, the wall thickness of the processed mold 10 is consistent, that is, the distance between the center of the sealed component 30 and the inner walls of the mold 10 is equal, thereby ensuring that after injection of glue, the thickness of the sealing layer of the sealed component 30 is consistent, thereby ensuring the quality of the sealed component 30.

[0029] Optionally, in an embodiment of the present invention, the mold 10 is a polytetrafluoroethylene mold. It can be understood that the material of the mold 10 can also be other plastic materials, such as perfluoroethylene propylene copolymer, polyvinylidene fluoride, etc., and is not limited to the materials listed in the embodiment of the present invention.

[0030] The glue pouring mold provided by the embodiment of the utility model avoids the adhesion problem after glue injection by setting the mold as a plastic mold. At the same time, there is no need to plate the inner wall of the mold, which ensures that the thickness of the sealing layer is consistent after the sealed part is injected with glue and sealed, thereby ensuring the quality of the sealed part. At the same time, plastic molds are cheaper than metal molds, which reduces manufacturing costs.

[0037] Specifically, the center of the vent hole 102 is located at the center of the joint line of the other end surface after the first half mold 11 and the second half mold 12 are molded together, that is, the center line of the vent hole 102 is also collinear with the center line of the mold 10 after closing.

[0038] like Figure 1 As shown, in the embodiment of the present invention, the fixture 20 is a cylindrical member 21 , and a portion of the mold 10 is sleeved in the cylindrical member 21 .

[0039] Specifically, in this embodiment, the fixture 20 may be a hollow cylindrical member 21 , and a portion of the mold 10 is sleeved in the cylindrical member 21 to close the first half mold 11 and the second half mold 12 .

[0040] Furthermore, if Figure 2 As shown, the fixture 20 also includes a bottom plate 22, which is arranged at one end of the cylindrical member 21. The bottom plate 22 is provided with a through hole, and the diameter of the through hole is smaller than the inner diameter of the cylindrical member 21. When the mold 10 is inserted into the cylindrical member 21, the mold 10 abuts against the bottom plate 22.

[0041] Specifically, in this embodiment, the fixture 20 is a cylindrical member 21 having a bottom plate 22. When the mold 10 is inserted into the fixture 20, the end surface of the mold 10 abuts against the bottom plate 22, so that the insertion length of the mold 10 can be positioned. The bottom plate 22 is provided with a through hole to facilitate the connection of the glue injection device with the glue injection hole 101.

[0042] Furthermore, in the embodiment of the present invention, the shape and size of the inner hole of the cylindrical member 21 are matched with the shape and size of the mold 10 one by one.

[0043] Specifically, the shape of the inner hole of the cylindrical member 21 matches the outer shape of the mold 10, and the internal space size of the cylindrical member 21 matches the outer shape of the mold 10. For example, when the outer shape of the mold 10 is circular, the inner hole of the cylindrical member 21 is a circular hole; when the outer shape of the mold 10 is rectangular, the inner hole of the cylindrical member 21 is also a rectangular hole.

The adjusting part is arranged in the cavity 103, and the part to be sealed 30 is arranged in the adjusting part, and the adjusting part is used to adjust the sealing thickness of the part to be sealed 30.

[0046] Specifically, the glue-filling mold provided in the embodiment of the utility model is not only suitable for the sealing of the hydroacoustic detector, but also can be applied to other components that need to be sealed. Since the external dimensions of the components to be sealed 30 are inconsistent, generally speaking, a component needs to be provided with a separate glue-filling mold for auxiliary processing thereof. In this embodiment, by providing an adjusting member, the thickness between the surface of the component to be sealed 30 and the inner wall of the adjusting member can be adjusted, thereby keeping the thickness of the sealing layer within a suitable range.
