Description

Technical Field

[0001] This utility model relates to the technical field of condensate removal equipment, and in particular to a condensate removal structure inside the cavity of a plastic oil tank mold. Background Technology

[0002] In humid weather, the temperature of the automotive plastic fuel tank mold is much lower than the ambient temperature, causing a large amount of condensation to form inside the mold cavity. This condensation can make the areas with characters on the surface of the plastic fuel tank uneven and blurry (to form characters on the surface of the plastic fuel tank, an installation groove is set inside the mold cavity, and an insert with the character information is installed in the installation groove), leading to customer complaints and product quality issues. Therefore, removing condensation from the areas corresponding to the characters inside the plastic fuel tank mold is particularly important. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problem of condensation in the area corresponding to the characters inside the plastic fuel tank mold, and to provide a structure for removing condensation inside the cavity of the plastic fuel tank mold.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A condensate removal structure for the cavity of a plastic fuel tank mold includes an insert with character information on its surface, a first air pipe, and a negative pressure assembly.

[0006] The insert has multiple air holes penetrating its surface and back, and the back of the insert has a connecting groove that connects the multiple air holes. The back of the insert is in close contact with the bottom of the mounting groove provided inside the cavity of the plastic oil tank mold.

[0007] Different pores lead to different locations of character information on the surface of the inlay;

[0008] One end of the first air tube enters the plastic oil tank mold from the back and connects with the connecting groove, while the other end is connected to the negative pressure component.

[0009] In this technical solution, the negative pressure component works to create a negative pressure difference between the insert inside the plastic oil tank mold cavity and the outside, thereby drawing the condensate on the surface of the insert into the first air pipe. The condensate is then discharged outside the plastic oil tank mold cavity after passing through the negative pressure component.

[0010] Furthermore, the different pores lead to different locations of character information on the surface of the insert, which can greatly improve the effect of absorbing condensate from the locations of character information on the surface of the insert through the pores.

[0011] Finally, multiple air holes are connected by a connecting groove, so that only the first air tube is needed to remove the condensate from the different character information locations.

[0012] Furthermore, the pore passes through one end of the insert surface and is placed within the surrounding structure of the character;

[0013] Enclosing structures include fully enclosed structures and semi-enclosed structures.

[0014] Inside the mold cavity of the plastic fuel tank, condensate is easily formed and trapped at the character information locations of the fully enclosed and semi-enclosed structures on the surface of the insert. The pores, with one end passing through the surface of the insert and placed within the fully enclosed or semi-enclosed structure of the character information, can further improve the effect of absorbing the condensate at the location of the character information on the insert surface through the pores.

[0015] Furthermore, the diameter of the vent is in the range of 0.4mm-0.6mm, which ensures that the vent can provide sufficient suction for the condensate due to negative pressure, without affecting the production and manufacturing of the plastic fuel tank.

[0016] Furthermore, an air passage connector is installed at the contact point between the first air pipe and the back of the plastic fuel tank mold, which not only prevents the first air pipe from detaching from the plastic fuel tank mold, but also ensures the sealing between the plastic fuel tank mold cavity and the first air pipe.

[0017] Furthermore, the negative pressure assembly includes a vacuum generator, a second air pipe, and an air compressor;

[0018] One end of the first air tube is connected to a vacuum generator;

[0019] The vacuum generator is connected to the air compressor via a second air pipe.

[0020] Furthermore, the negative pressure assembly also includes a pneumatic triplet;

[0021] The pneumatic triplet is connected between one end of the first air tube and the vacuum generator.

[0022] Compared with existing technologies, the principles and advantages of this technical solution are as follows:

[0023] 1. The negative pressure component creates a negative pressure difference between the insert inside the plastic fuel tank mold cavity and the outside, drawing condensate from the insert surface into the first air pipe. The condensate then passes through the negative pressure component and is discharged outside the mold cavity. Furthermore, different air vents lead to different locations on the insert surface containing character information, significantly improving the effectiveness of removing condensate from these locations. Finally, a connecting groove links the multiple air vents, allowing the first air pipe alone to remove condensate from all locations containing character information.

[0024] 2. Inside the mold cavity of the plastic fuel tank, condensate is easily formed and trapped at the character information locations of the fully enclosed and semi-enclosed structures on the surface of the insert. The vents, with one end passing through the surface of the insert and placed within the fully enclosed or semi-enclosed structure of the character information, can further improve the effect of absorbing the condensate at the location of the character information on the insert surface through the vents.

[0025] 3. The diameter of the vent is in the range of 0.4mm-0.6mm, which ensures that the vent can provide sufficient suction for condensate due to negative pressure, without affecting the production and manufacturing of the plastic fuel tank.

[0026] 4. An air connection is installed at the contact point between the first air pipe and the back of the plastic oil tank mold. This not only prevents the first air pipe from detaching from the plastic oil tank mold, but also ensures the sealing between the plastic oil tank mold cavity and the first air pipe.

[0039] The present invention will be further described below with reference to two specific embodiments:

[0040] Example 1

[0041] like Figures 1 to 8 As shown in the figure, the condensate removal structure inside the cavity of the plastic fuel tank mold described in this embodiment includes an insert 1 with character information on its surface, a first air pipe 2, and a negative pressure component 3.

[0042] The insert 1 has multiple air holes 4 penetrating its surface and back, and the back of the insert 1 is provided with a connecting groove 5 that connects the multiple air holes 4. The back of the insert 1 is in close contact with the bottom of the mounting groove 6 provided inside the cavity of the plastic oil tank mold 11. Different air holes 4 lead to different character information positions on the surface of the insert 1. One end of the first air pipe 2 enters the plastic oil tank mold 11 from the back and connects with the connecting groove 5, and the other end is connected to the negative pressure component 3.

[0043] Specifically, in this embodiment, one end of the vent 4 passing through the surface of the insert 1 is placed within the enclosure structure of the character; the enclosure structure includes a fully enclosed structure and a semi-enclosed structure. Characters with a fully enclosed structure include “8”, “9”, “O”, “D”, “P”, “R”, etc., and characters with a semi-enclosed structure include “E”, “H”, “K”, etc. Figure 6 As shown.

[0044] Specifically, in this embodiment, the diameter of the pore 4 is 0.5 mm.

[0045] Specifically, in this embodiment, an air passage connector 7 is installed at the contact point between the first air pipe 2 and the back of the plastic oil tank mold 11.

[0046] Specifically, in this embodiment, the negative pressure component 3 includes a vacuum generator 8, a second air pipe 9, and an air compressor; one end of the first air pipe 2 is connected to the vacuum generator 8; the vacuum generator 8 is connected to the air compressor through the second air pipe 9.

[0047] The working principle of this embodiment is as follows:

[0048] The air compressor supplies compressed air to the vacuum generator 8 through the second air pipe 9. The vacuum generator 8 generates negative pressure based on the compressed air, creating a negative pressure difference between the insert 1 inside the cavity of the plastic oil tank mold 11 and the outside. This draws condensate on the surface of the insert 1 into the first air pipe 2, and the condensate is then discharged outside the cavity of the plastic oil tank mold 11 after passing through the negative pressure component 3. Furthermore, different air holes 4 lead to different locations of character information on the surface of the insert 1, greatly improving the effectiveness of removing condensate from these locations. Finally, the multiple air holes 4 are connected by the connecting groove 5, allowing only the first air pipe 2 to remove condensate from different locations.

[0049] Inside the cavity of the plastic fuel tank mold 11, condensation water is easily formed and trapped at the character information locations of the fully enclosed and semi-enclosed structures on the surface of the insert 1. The vent 4 passes through one end of the surface of the insert 1 and is placed within the fully enclosed or semi-enclosed structure of the character information, which can further improve the effect of absorbing the condensation water at the location of the character information on the surface of the insert 1 through the vent 4.

[0050] The diameter of vent 4 is 0.5mm, which ensures that vent 4 can provide sufficient suction for condensate due to negative pressure, without affecting the production and manufacturing of the plastic fuel tank.

[0051] An air passage connector 7 is installed at the contact point between the first air pipe 2 and the back of the plastic oil tank mold 11. This not only prevents the first air pipe 2 from detaching from the plastic oil tank mold 11, but also ensures the sealing between the cavity of the plastic oil tank mold 11 and the first air pipe 2.

[0052] Example 2

[0053] like Figure 9 As shown, compared with Embodiment 1, the condensate removal structure inside the plastic oil tank mold cavity in this embodiment also includes a pneumatic triplet 10, which is connected between one end of the first air pipe 2 and the vacuum generator 8.

[0054] In this embodiment, the condensate in the character area on the surface of the insert 1 inside the cavity of the plastic fuel tank mold 11 is first discharged through the pneumatic triplet 10, and then the vacuum generator 8 performs secondary drainage.

[0055] Compared to Embodiment 1, this embodiment has a better drainage effect, and it does not require all the condensate that passes through the first air pipe 2 to be discharged through the vacuum generator 8, thus improving the service life of the vacuum generator 8.

[0056] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all changes made in accordance with the shape and principle of this utility model should be covered within the protection scope of this utility model.
