Technical Field

[0001] The present application relates to the technical field of sealing strips, and in particular to a sealing strip forming mold used in a cardiopulmonary function testing booth. Background Art

[0002] Sealing strips are an auxiliary tool commonly used in various chemical and daily necessities to seal liquids or gases to isolate the inside from the outside world, preserve items or create a stable environment. Depending on the items that need to be sealed, there are many different sealing strips on the market. Among them, silicone sealing strips have the characteristics of insulation and good weather resistance.

[0003] The silicone sealing strips used in existing cardiopulmonary function test booths are often made by extrusion. When an extrusion mold is used to make a U-shaped sealing strip, the mold structure required is complex and the sealing strip needs to be inserted into the mold, which makes the installation cumbersome and inefficient. Therefore, in order to improve the deficiencies of the existing technology, the inventors proposed a sealing strip forming mold for cardiopulmonary function test booths. Utility Model Content

[0035] Example

[0036] This embodiment provides a sealing strip forming mold for a cardiopulmonary function test booth, which is made by glue pouring. Figure 1 and Figure 2 As shown, it includes a base plate 1, an intermediate forming plate 2 and a cover plate 3 that cooperate with each other. The junction of the base plate 1, the intermediate forming plate 2 and the cover plate 3 forms a forming groove for pouring liquid silicone.

[0037] like Figure 3 As shown, the base plate 1 is rectangular as a whole, and includes a first forming portion 11 and a first connecting portion 12 arranged sequentially from the outside to the inside. The first connecting portion 12 is in the shape of a step that rises sequentially from the outside to the inside, and the height of its lowest point is greater than the height of the connection point with the first forming portion 11.

[0038] In this embodiment, a top outlet 13 is provided in the middle of the first connecting portion 12 for facilitating separation of the bottom plate 1 and the intermediate forming plate 2 .

[0039] As shown in Figure 4 The intermediate forming plate 2 includes a second forming part 21 and a second connecting part 22, which matches the first connecting part 12 to facilitate assembly and avoid glue running. The second forming part 21 is arranged around the second connecting part 22. After the intermediate forming plate 2 is assembled with the bottom plate 1, an L-shaped first glue pouring groove is provided between the second forming part 21 and the first forming part 11.

[0040] In this embodiment, the middle part of the second connecting part 22 is provided with an embedded block, which is embedded in the ejection port 13 to facilitate the ejection of the intermediate forming plate 2.

[0041] As shown in Figure 5 The top of the second connecting part 22 is provided with an overflow cavity 23, which is provided with a plurality of overflow holes 24 near the third forming plate side. After liquid silicone is poured into the forming groove, the excess liquid silicone flows into the overflow cavity 23 through the overflow holes 24 to prevent too much silicone from being poured into the forming groove.

[0042] As shown in Figure 6 The cover plate 3 includes a third forming part 31 and a third connecting part 32, the bottom of the third connecting part 32 abuts against the top of the first forming part 11 and the second connecting part 22, and the third forming part 31 is arranged above the second forming part 21 at the bottom of the third connecting part 32. A U-shaped forming groove is formed by the first glue pouring groove and the second glue pouring groove between the second forming part 21 and the third forming part 31.

[0043] In this embodiment, the third forming part 31 is provided with an overflow channel 33 at a position corresponding to the overflow hole 24, which connects the overflow cavity 23 and the forming groove. During the assembly of the cover plate 3, the excess liquid silicone can flow into the overflow cavity 23 through the overflow channel 33 and the overflow hole 24.

[0044] In this embodiment, in order for the liquid silicone to flow into the overflow cavity 23, the top of the overflow cavity 23 is provided with an exhaust hole 34 to exhaust the gas inside the overflow cavity 23.

[0045] In this embodiment, in order to facilitate the separation of the bottom plate 1 and the cover plate 3, the first forming part 11 and the third connecting part 32 are provided with a pry table 4 at a position corresponding thereto. After the cover plate 3 is assembled, the pry tables 4 have pry openings for the insertion of a pry bar.

[0046] The technical features of the above embodiments can be combined in any way. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.

[0047] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
