Description

Technical Field

[0001] This utility model relates to the field of injection molds, and in particular to an injection mold for a long and narrow automotive decorative part. Background Technology

[0002] Injection molds for elongated automotive trim parts are molds specifically designed for producing interior or exterior trim components for automobiles. These components typically have slender shapes, such as center console panels, door trim strips, and dashboard trim strips.

[0003] When using injection molds to produce elongated automotive trim parts, due to the characteristics of these parts, some of the injection material solidifies when it enters the mold due to the mold's temperature, resulting in a snake-like texture on the trim parts. Current solutions typically involve multiple injection cycles to preheat the mold, but this method leads to material waste and requires reheating after shutdown, thus introducing certain defects.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figure 1-3 The image shows an injection mold for a narrow, elongated automotive trim part.

[0035] Example 1: Includes a first mold 1, a second mold 2, and a heating assembly. The second mold 2 is mounted on the first mold 1. The first mold 1 and the second mold 2 work together to injection mold elongated automotive trim parts. The heating assembly is mounted on both the first mold 1 and the second mold 2. The heating assembly includes a sealing plate 31, a heating element 32, and a locking assembly 34. The sealing plate 31 is located on the side of the first mold 1, and the heating assembly on the second mold 2 is installed in the same way as the heating assembly on the first mold 1. The heating element 32 is fixedly mounted on one side of the sealing plate 31. Both the first mold 1 and the second mold 2 have grooves on their sides, and the heating element 32 is fitted into the grooves. The heating element 32 is a resistance heating element, and the sealing plate 31 is provided with wiring holes. The wiring method is existing technology and will not be described in detail here. The heating element 32 is energized and heats up, which can heat the first mold 1 and the second mold 2, thereby reducing the appearance of snake-like patterns on the outside of the injection molding material when it enters the first mold 1 and the second mold 2 for molding. The locking component 34 is provided at the end of the first mold 1. The locking component 34 is used to lock the sealing plate 31. By releasing the locking component 34 from the locking state of the sealing plate 31, the sealing plate 31 and the heating element 32 can be directly disassembled, so as to facilitate the disassembly and maintenance of the heating element 32.

[0036] Furthermore, the heating assembly also includes a docking rod 33 and a docking groove. One end of the docking rod 33 is fixedly connected to the sealing plate 31, and the docking groove is opened on the side of the first mold 1. The outer wall of the docking rod 33 is slidably engaged with the inner cavity of the docking groove. The docking rod 33 can improve the stability of the sealing plate 31 set on the side of the first mold 1.

[0037] Example 2: Based on Example 1, the locking assembly 34 includes a locking plate 341, a positioning rod 342, and a limiting rod 343. The locking plate 341 is snapped onto the end of the first mold 1, and the positioning rod 342 is fixedly connected to the end of the sealing plate 31. A positioning hole is provided on one side of the locking plate 341, and the outer wall of the positioning rod 342 is slidably snapped onto the inner cavity of the positioning hole. One end of the limiting rod 343 is fixedly connected to the locking plate 341. A limiting groove is provided on the side of the first mold 1, and the outer wall of the limiting rod 343 is slidably snapped onto the inner cavity of the limiting groove. Under the action of the limiting rod 343, the locking plate 341 can be snapped onto and limited by the positioning rod 342, thereby ensuring the stability of the sealing plate 31 installation.

[0038] Furthermore, the locking assembly 34 also includes a restraining plate 345, a fixed housing 344, and a connector 346. The restraining plate 345 is disposed on one side of the locking plate 341. One side of the fixed housing 344 is fixedly connected to the first mold 1. The connector 346 is slidably disposed inside the fixed housing 344. The other side of the fixed housing 344 has a sliding hole that matches the connector 346. One side of the connector 346 is fixedly connected to the restraining plate 345. The restraining plate 345 can restrain and limit the locking plate 341 through the connector 346, thereby ensuring the stability of the locking plate 341 in engaging with the sealing plate 31. When the restraining plate 345 is slid apart from the locking plate 341, the locking plate 341 can be separated from the positioning rod 342, thereby unlocking the sealing plate 31.

[0039] Furthermore, the locking assembly 34 also includes a fixing block 347, a guide rod 349, and a limiting spring 348. The fixing block 347 is fixedly connected to the inside of the fixing housing 344. One end of the guide rod 349 is fixedly connected to the fixing block 347. The outer wall of the guide rod 349 is slidably sleeved with the connector 346. The limiting spring 348 is slidably sleeved on the outside of the guide rod 349. The limiting spring 348 is located between the fixing block 347 and the connector 346. The limiting spring 348 can provide an elastic compressive force to the restraining plate 345 through the connector 346, thereby ensuring the stability of the restraining plate 345 when it is locked to one side of the locking plate 341.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
