Description

Technical Field

[0001] The invention relates to the technical field of molds, in particular to a Hough loose-block air filter tube mold. Background Art

[0002] like Figure 1 As shown, the air filter intake pipe is a connecting hose between the automobile throttle and the air filter, and is the air intake channel of the engine. Due to the different layouts of automobile engines of various brands and models, the degree of distortion of the air filter intake pipe is different. The air filter intake pipe has a high degree of distortion, and the two turns present three-dimensional distortion in space, which complicates the mold parting. When the engine is working and inhaling air, the intake pipe is in a negative pressure state. In order to ensure that the air filter intake pipe has enough resistance to negative pressure and is not sucked flat, the outer wall of the air pipe is covered with vertical and horizontal ribs. These ribs bring inconvenience to mold processing and product demolding. Summary of the invention

[0022] Reference Figure 2-Figure 7 The present invention provides a half block air filter tube mold, comprising an upper mold, a lower mold, a first half block 1, a second half block 2 and a mold core, wherein:

[0023] The upper mold includes an upper pad 3 and an upper mold plate 4 installed at the bottom end of the upper pad 3 . A gate is provided on the upper pad 3 , a gate sleeve 5 is installed in the gate, and an upper mold cavity 6 is provided at the bottom end of the upper mold plate 4 .

[0024] The lower mold includes a lower pad 7 and a lower mold plate 8 installed on the top of the lower pad 7. The lower mold plate 8 is located below the upper mold plate 4, and a lower mold cavity 9 is formed at the top of the lower mold plate 8 relative to the upper mold cavity 6.

[0025] The first half block 1 and the second half block 2 are relatively installed on the top of the lower pad 7 and located on the side of the lower template 8. The distance between the first half block 1 and the second half block 2 is adjustable. The first half block 1 is provided with a first mold cavity 10 on the side close to the second half block 2, and the second half block 2 is provided with a second mold cavity 11 on the side close to the first half block 1.

[0026] In the mold closing state, the upper mold cavity 6, the lower mold cavity 9, the first mold cavity 10, and the second mold cavity 11 cooperate to form a molding cavity, and the mold core is assembled in the molding cavity.

[0027] When the mold of the present invention is opened, the upper and lower molds are opened, and the first half block 1 and the second half block 2 fall together with the lower mold, and then the first half block 1 and the second half block 2 are separated, so that the upper transverse ribs of the product are separated from the first half block 1 and the second half block 2, and the transverse ribs no longer hinder the demoulding of the product. Although the rubber product demoulding product has elastic concession, due to the high air tube ribs and the thick product wall thickness of generally 2.5-5mm, if the first half block 1 and the second half block 2 are not taken out of the mold by force, the root of the product ribs is easy to be torn, and the product is scrapped.

[0028] The present invention has a first half block 1 and a second half block 2, so that the actual depth of the upper mold cavity is greatly reduced, and the cavity mouth space is enlarged, so that the cavity and the matching part can be processed by five axes, that is, the machining tool axis can be tilted, which greatly reduces the extension length of the tool clamping, enhances the tool rigidity, and ensures that the qualified size is processed. The cavity of the half part can be placed horizontally for processing, and the depth of the first cavity 10 and the second cavity 11 is only about 40, which can be processed by an ordinary three-axis machine tool.

[0029] In this embodiment, a guide rail 12 is installed at the top of the lower pad 7 on one side of the lower template 8, and the first half block 1 and the second half block 2 are both slidably installed on the guide rail 12. The first half block 1 and the second half block 2 are respectively installed with a first handle 13 and a second handle 14.

[0030] In a specific embodiment, the bottom of the upper template 4 is provided with an inclined block 15 that cooperates with the first half block 1 and the second half block 2. The lower template 8 is provided with an inclined surface 16 that cooperates with the first half block 1 and the second half block 2. The upper template 4 cooperates with the first half block 1 and the second half block 2 on all sides with inclined surfaces, and the lower template 8 cooperates with the first half block 1 and the second half block 2 with inclined surfaces. The press moves up and down and the inclined block generates a horizontal force component, the first half block 1 and the second half block 2 are squeezed and pressed tightly, and the first half block 1 and the second half block 2 are also positioned and clamped on the left and right under the action of the upper and lower mold inclined surfaces, so that the mold forms a tight and closed cavity.

[0031] In a specific embodiment, the mold core includes a mold core A and a mold core B. The mold core A is arranged between the upper mold plate 4 and the lower mold plate 8 , and the mold core B is arranged between the first half block 1 and the second half block 2 .

[0032] In a specific embodiment, a lifting template 17 is further included. The lifting template 17 is connected to the lower pad 7 through positioning pins. A plug 18 that can extend into the molding cavity is installed on the lifting template 17.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
