Description

Technical field:

[0001] The utility model belongs to the technical field of engine processing equipment, in particular to an intake manifold mold. Background technology:

[0002] The intake manifold is the passageway connecting to the engine's cylinders, allowing air to enter. Traditionally, it's made of cast metals like aluminum alloys. However, in recent years, plastic intake manifolds have become increasingly popular to reduce engine weight and production costs. During production, a plastic intake manifold is first injection-molded into two separate parts: the upper and lower intake manifold shells. These two parts are then joined and secured together.

[0003] However, most existing intake manifold molds are simple combinations of upper and lower mold plates forming a mold cavity. The outer wall surface of the bronchial duct of the upper half shell of the injection-molded intake manifold is a smooth structure, and the contact area between the end face of the bronchial duct and the corresponding end face of the lower half shell of the intake manifold is relatively limited. If the connection strength is to reach the expected level, the overall pipe wall thickness can only be thickened, which is costly. Summary of the invention:

[0004] The purpose of the utility model is to provide an intake manifold mold, which cooperates with the upper and lower templates in the horizontal direction with the help of a horizontal template assembly, and can effectively expand the upper and lower end surface areas of the bronchial row without increasing the thickness of the bronchial row wall, thereby increasing the contact area and connection strength between the bronchial row and other pipelines.

[0005] The utility model is achieved in that:

[0006] An intake manifold mold includes an upper template and a lower template. The upper template and the lower template are buckled together to form a mold cavity for injection molding an upper half shell of the intake manifold. The upper half shell of the intake manifold includes a bronchial row and an intake half shell arranged on one side of the bronchial row. The upper and lower outer edges of the bronchial row extend outward to form an upper ring protrusion and a lower ring protrusion respectively. A structural groove is formed between the upper and lower ring protrusions. A horizontal template assembly is horizontally arranged between the upper and lower templates.

[0007] When the structural slots are arranged on both sides of the exhaust pipe body, the horizontal template assembly includes a fixed horizontal template and a movable horizontal template respectively located on both sides of the exhaust pipe body. The structures of the fixed horizontal template and the movable horizontal template located in the mold cavity are respectively consistent with the structures of the structural slots on the corresponding sides, and the movable horizontal template can move horizontally inward and outward relative to the exhaust pipe body.

[0008] When the structural slot and the air intake half shell are respectively located on both sides of the bronchial row, the horizontal template assembly includes a fixed horizontal template, and the structure of the fixed horizontal template located in the mold cavity is consistent with the structure of the structural slot.

[0009] In the above-mentioned intake manifold mold, a horizontal sliding cavity is provided between the upper template and the lower template, which is connected to the mold cavity through a slot and is used for the movable horizontal template to move. A guide inclined surface is provided on the movable horizontal template facing away from the mold cavity. A driving block is fixed on the lower template, and a driving inclined surface is provided on the driving block that can fit with the guide inclined surface. The driving block is driven by the lower template to move relatively upward to push the movable horizontal template toward the mold cavity.

[0010] In the above-mentioned intake manifold mold, the lower template is fixed with a reset slide rod inclined along the guide inclined surface, and a strip sliding groove is provided on the upper template located in the horizontal sliding cavity. The upper end of the reset slide rod passes through the movable horizontal template and slides into the strip sliding groove.

[0011] In the above-mentioned intake manifold mold, a horizontal movable groove is provided on the bottom surface of the upper template, and the horizontal sliding cavity is formed between the horizontal movable groove and the lower template, and a matching movable groove is provided on the bottom surface of the horizontal movable groove, and the top of the movable horizontal template has a matching boss portion that is slidably connected in the matching movable groove.

[0012] In the above-mentioned intake manifold mold, a limit groove connected to the horizontal moving groove is provided on the bottom surface of the upper template, and a limit plug that can be inserted into the limit groove is fixed on the top surface of the lower template. Part of the limit plug extends into the horizontal moving groove and forms a vertical limit gap between the limit block and the bottom surface of the horizontal moving groove. The side wall of the movable horizontal template has a limit protrusion that slides into the vertical limit gap.

[0013] In the above-mentioned intake manifold mold, a positioning groove is provided on the upper template located in the horizontal sliding cavity, a positioning block is provided in the positioning groove, and a positioning protrusion extending out of the notch of the positioning groove is provided on the bottom surface of the positioning block. An inner positioning groove and an outer positioning groove are provided on the top surface of the movable horizontal template along its horizontal moving direction, both of which can be used for the positioning protrusion to be inserted. When the movable horizontal template moves toward the mold cavity to the extreme position, the positioning protrusion is plugged into the inner positioning groove; when the movable horizontal template moves away from the mold cavity to the extreme position, the positioning protrusion is plugged into the outer positioning groove.

[0014] The outstanding advantages of the utility model compared with the prior art are:

With the help of the horizontal template component cooperating with the upper and lower templates in the horizontal direction, the upper and lower end surface areas of the bronchial row can be effectively expanded without increasing the wall thickness of the bronchial row, thereby increasing the contact area and connection strength between the bronchial row and other pipelines.

[0023] The present invention is further described below with reference to specific embodiments. Figure 1 —6:

[0024] An intake manifold mold includes an upper template 1 and a lower template 2. The upper template 1 and the lower template 2 are buckled together to form a mold cavity for injection molding an upper half shell 3 of the intake manifold. The upper half shell 3 of the intake manifold includes a bronchial row 4 and an intake half shell 5 arranged on one side of the bronchial row 4. The upper and lower outer edges of the bronchial row 4 extend outward to form an upper ring protrusion 6 and a lower ring protrusion 7, respectively. A structural groove is formed between the upper ring protrusion 6 and the lower ring protrusion 7. A horizontal template assembly is horizontally arranged between the upper template 1 and the lower template 2.

[0025] When the structural slot and the air intake half shell 5 are respectively located on both sides of the bronchial row 4, the horizontal template assembly includes a fixed horizontal template 8, and the structure of the fixed horizontal template 8 located in the mold cavity is consistent with the structure of the structural slot.

[0026] In this embodiment, when the structural slots are provided on both sides of the exhaust pipe body, the horizontal template assembly includes a fixed horizontal template 8 and a movable horizontal template 9, respectively located on either side of the exhaust pipe body. The structures of the fixed horizontal template 8 and the movable horizontal template 9 within the mold cavity correspond to the structures of the structural slots on the corresponding sides, and the movable horizontal template 9 can move horizontally inward and outward relative to the exhaust pipe body. It should be noted that the coordination of the fixed horizontal template 8 and the movable horizontal template 9 enables the injection-molded intake manifold upper half shell 3 to be effectively demolded.

[0027] The utility model has a reasonable design. With the help of the horizontal template component cooperating with the upper and lower templates 2 in the horizontal direction, the upper and lower end surface areas of the bronchial row 4 can be effectively expanded without increasing the wall thickness of the bronchial row 4, thereby increasing the contact area and connection strength between the bronchial row 4 and other pipelines.

[0028] Furthermore, in the present embodiment, the specific driving structure for the horizontal movement of the movable horizontal template 9 between the upper template 1 and the lower template 2 is as follows: a horizontal sliding cavity is provided between the upper template 1 and the lower template 2, which is connected to the mold cavity through a slot and is used for the movement of the movable horizontal template 9; a guide inclined surface 10 is provided on the movable horizontal template 9 facing away from the mold cavity; a driving block 11 is fixed on the lower template 2; a driving inclined surface 12 is provided on the driving block 11 which can fit with the guide inclined surface 10; and the driving block 11 is driven by the lower template 2 to move relatively upward to push the movable horizontal template 9 toward the mold cavity.

[0029] At the same time, in order to allow the movable horizontal template 9 to move away from the fixed horizontal template 8 when the upper template 1 and the lower template 2 are separated up and down, the lower template 2 is fixed with a reset slide rod 13 inclined along the guide inclined surface 10, and a strip sliding groove 14 is provided on the upper template 1 located in the horizontal sliding cavity. The upper end of the reset slide rod 13 passes through the movable horizontal template 9 and slides into the strip sliding groove 14.

[0030] In order to further improve the sliding stability of the movable horizontal template 9 in the horizontal sliding cavity, a horizontal moving groove 15 is opened on the bottom surface of the upper template 1, and the horizontal sliding cavity is formed between the horizontal moving groove 15 and the lower template 2, and a matching movable groove 16 is opened on the bottom surface of the horizontal moving groove 15, and the top of the movable horizontal template 9 has a matching boss portion 17 that is slidably connected in the matching movable groove 16.

[0031] Furthermore, in order to enable the mobile horizontal template 9 to move horizontally in the horizontal moving groove 15 during the up and down displacement of the upper template 1 and the lower template 2, a limit groove 18 connected to the horizontal moving groove 15 is provided on the bottom surface of the upper template 1, and a limit plug 19 that can be inserted into the limit groove 18 is fixed on the top surface of the lower template 2. Part of the limit plug 19 extends into the horizontal moving groove 15 and forms a vertical limit gap between the bottom surface of the horizontal moving groove 15. The side wall of the movable horizontal template 9 has a limit protrusion 20 that slides in the vertical limit gap.

[0032] In addition, in order to ensure that the position of the movable horizontal template 9 is fixed during injection molding, a positioning groove 21 is provided on the upper template 1 located in the horizontal sliding cavity, a positioning block 22 is provided in the positioning groove 21, and the bottom surface of the positioning block 22 is provided with a positioning protrusion 23 extending out of the notch of the positioning groove 21. The top surface of the movable horizontal template 9 is provided with an inner positioning groove and an outer positioning groove 24 along its horizontal moving direction, both of which can be used for the positioning protrusion 23 to be inserted. When the movable horizontal template 9 moves toward the mold cavity to the extreme position, the positioning protrusion 23 is plugged into the inner positioning groove; when the movable horizontal template 9 moves away from the mold cavity to the extreme position, the positioning protrusion 23 is plugged into the outer positioning groove 24.

[0033] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
