Description

Technical Field

[0001] The utility model relates to the technical field of automotive instrument panel covering, and specifically to a local heating structure for a doghouse structure of an automotive interior part. Background Art

[0002] Before the assembly of automotive interior parts, a series of process treatments will be carried out. The hot pressing and covering process is one of the important processes for automotive interior parts, aiming to enhance the overall luxury feeling of the automotive interior and its sound insulation and fire prevention functions. After plastic parts such as automotive door panels are injection molded, a layer of leather is covered. Hot pressing and covering is a process of covering the leather with glue on the plastic parts by external heating. This process mainly aims to integrally combine the leather and the plastic parts. However, the temperature requirement in the covering process is particularly important. The glue adheres to the leather and then is heated and covered with the plastic parts. Usually, the heating method is through the way of flowing hot water. However, the local features of the doghouse (in automotive interior parts, "doghouse" refers to a common structure, which can be called "doghouse structure" in Chinese. The reason for this name is that its shape is similar to a doghouse) on the plastic parts are large, resulting in the situation that the local doghouse structure cannot be heated locally, and thus there will be phenomena such as the local part of the doghouse structure not being heated and the covered area of the product being not firmly covered and bulging. Summary of the Utility Model

[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides that the best effect can be achieved by continuously blowing hot air on the local doghouse structure by using a heater to heat the air, and the covered plastic parts are very firm.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A local heating structure for a doghouse structure of an automotive interior part, comprising a mold 1, a heater 2 and a hot air duct 3; wherein, a through blowing channel 5 is arranged at the bottom of the local doghouse structure 4 of the mold 1, and the blowing channel 5 is connected to an external hot air duct 3; the heater 2 is connected to the hot air duct 3, and the hot air duct 3 transmits the hot air to the local doghouse structure 4 on the mold 1 through the blowing channel 5.

[0006] The utility model also has the following additional technical features:

[0007] As a further specific optimization of the technical solution of the utility model: The local doghouse structures 4 are arranged at multiple positions on the mold 1, respectively located at the left part, the middle part and the right part of the mold 1.

[0008] As a further specific optimization of the technical solution of the utility model: The blowing channels 5 of each local doghouse structure 4 are respectively aggregated into the hot air duct 3.

[0009] Compared with the prior art, the advantages of the present utility model are as follows:

[0010] Advantage 1: The present utility model heats the local part 4 of the dog house structure of the product by hot air. The heater heats the air and blows it towards the local part 4 of the dog house structure, so that the temperature of the local part 4 of the dog house structure can be made uniform, and the coating effect can reach the best.

[0011] Advantage 2: The local heating structure of the dog house structure of the present utility model replaces the traditional hot water heating. There are gaps in the local part 4 of the dog house structure, and hot water heating cannot effectively heat the local part 4 of the dog house structure. Using hot air heating can more effectively heat the local part 4 of the dog house structure of the product, and the plastic parts coated are very firm.

[0012] Advantage 3: The heater of the present utility model transmits hot air to the holes corresponding to the local part 4 of the dog house structure of the mold through the hot air pipe, and blows hot air towards the local part 4 of the dog house structure to make the local part 4 of the product dog house structure reach a specific temperature, which plays a very good role in the subsequent coating of the product.
