Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to an integrated foaming mould of a seat back plate with luminous lines. Background Art

[0002] Passengers spend more and more time in the cabin, and have higher and higher requirements for riding experience and comfort. When the journey is no longer a short compromise, how to optimize and improve seat comfort has become an important issue at present, and smart car seats have come into being. As a device that directly contacts the driver and passengers, the seat plays a vital role in the user experience and is also one of the factors that distinguish the level of automobile manufacturers. Conventional seat back panels generally simply lay the fabric single leather flat and fix it on the lower mold of the aluminum mold, and then pour the polyurethane material after the mold is completely closed to achieve one-piece foaming to make the back panel finished product. The back panel and the luminous LOGO cannot be integrated into one, and the customer's desire to add a LOGO of any size and font to any position on the back panel cannot be met. In view of the temperature requirements during the back panel pouring and mold opening process, the current molds often cannot be adjusted separately according to the pouring requirements of the upper and lower molds. Utility Model Content

[0003] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide an integrated foaming mold for a seat back panel with luminous lines that can realize integrated molding of the back panel and the luminous LOGO and meet customer needs, and at the same time can cool down separately according to the casting requirements of the upper and lower molds of the mold.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: an integrated foaming mold for a seat back panel with a luminous line, comprising an upper mold and a lower mold. A mold material pouring port is provided on the top surface of the upper mold. The inner side surface of the lower mold is paved with a back panel fabric, and the back panel fabric is sewn with luminous lines. Two notches consistent with the diameter of the luminous lines are provided at the frame of the lower mold, so that the terminal ends of the luminous lines extend through the notches in the frame of the lower mold and are placed outside the back panel as a whole to connect with the seat wiring harness. Water pipes are provided between the upper mold and the lower mold, as well as between the lower mold and the bottom of the mold for temperature control.

[0005] Preferably, the mold material pouring port is a through hole arranged in the middle of the upper mold of the mold.

[0006] Preferably, a base is provided under the lower mold of the mold, and the base is fixedly connected to the lower mold of the mold by bolts.

[0007] Preferably, the upper mold and the lower mold are fitted with curved surfaces.

[0008] Preferably, the upper mold and the lower mold are both made of aluminum alloy.

[0009] The beneficial effects of the utility model are as follows: the fabric with the luminous line sewn on it is fixed on the lower mold of the mold, the lower mold and the upper mold are molded together and poured and then matured, and the mold is opened to form a seat back panel that meets the customer's requirements, which can not only realize the integrated molding of the back panel and the luminous LOGO, but also meet the customer's needs; water pipes are added to the upper and lower molds of the mold, and the temperature can be adjusted according to the needs of the upper and lower molds of the mold respectively.

[0014] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] like Figure 1 —2 shows an integrated foaming mold for a seat back panel with luminous lines, which is mainly composed of an upper mold 5 and a lower mold 4.

[0016] The material of the mold upper mold 5 and the mold lower mold 4 are both aluminum alloy, and a base 6 is provided under the mold lower mold 4, and the base 6 is fixedly connected to the mold lower mold 4 by bolts. The mold upper mold 5 and the mold lower mold 4 are fitted with curved surfaces, so that the mold upper mold 5 and the mold lower mold 4 are directly buckled and tightly fitted.

[0017] The top surface of the mold upper mold 5 is provided with a mold material pouring port 5a, which is a through hole arranged in the middle of the mold upper mold 5. The inner side of the mold lower mold 4 is paved with a backing plate fabric 2, and the backing plate fabric 2 is sewn with luminous lines 3, which are sewn according to a certain pattern, such as Figure 3The star-shaped pattern is shown. The back panel body 1, the back panel fabric 2 and the luminous wire 3 are integrally foamed, and the lower mold 4 and the upper mold 5 are molded together for casting and then matured to obtain the finished back panel product. The frame of the lower mold is provided with two notches that are consistent with the diameter of the luminous wire, so that the terminal ends of the luminous wire 3 extend through the notches of the frame of the lower mold and are placed outside the back panel as a whole to connect with the seat harness. Since the luminous material in the luminous wire 3 is sensitive to the heating temperature, different temperature control is required for the upper mold 5 and the lower mold 4 during casting and molding, wherein the upper mold 5 is required to be maintained at 45-65°C and the lower mold 4 is required to be maintained at 40-60°C. Therefore, water pipes are provided between the upper mold 5 and the lower mold 4 and between the lower mold 4 and the base 6 to control the temperature and adjust the mold temperature.

[0018] During the production process, the luminous wire 3 is first sewn on the outer side of the back panel fabric 2 according to the required LOGO pattern, the back panel fabric 2 with the luminous LOGO sewn is fixed on the lower mold 4 of the mold, and then the mold is closed for closed mold casting, and the mold is opened after curing.

[0019] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
