Description

Technical Field

[0001] The utility model relates to the technical field of automobile sealing component production, in particular to an automobile sealing component forming die. Background Art

[0002] As the name implies, automotive seals are sealing parts used in cars, mainly made of elastomers. All the functions of automotive seals are to prevent leakage or sound insulation and shock absorption. Most automotive seals are made of rubber, and the elastic elements in mechanical seals are made of metal and non-metallic sealing materials to achieve the ultimate "sealing effect".

[0003] Most of these automotive seals are injection molded using a molding mold. Many seals are small in size, so most seal molding molds are provided with multiple molding grooves, so that multiple seals can be molded and produced at one time. However, when injecting rubber materials, the flow rate of the hot-melt rubber is too slow, resulting in a long time for it to fill the entire molding groove, which makes the molding process time too long and the processing efficiency becomes low. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and provides a molding die for automobile sealing parts.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-6A molding die for automobile seals comprises a bottom plate 1, a fixing seat 2 is symmetrically arranged on both sides of the upper end surface of the bottom plate 1, a lower die seat 3 is horizontally arranged on the upper end of the fixing seat 2, an upper die seat 4 is horizontally arranged above the lower die seat 3, a top plate 5 is horizontally fixedly connected to the top of the upper die seat 4, and fixing guide pillars 6 are penetrated at the four corners of the lower die seat 3 and the upper die seat 4, and the fixing guide pillars 6 are fixed on the upper surfaces of the fixing seats 2 on both sides.

[0021] A plurality of molding grooves 31 are evenly formed on the upper surface of the lower mold base 3 , and a flow channel 32 is formed between the molding grooves 31 on two adjacent sides. The plurality of molding grooves 31 facilitates one-time injection molding of a plurality of sealing components.

[0022] In addition, the flow channel 32 includes a main flow channel 321, which is connected to the molding grooves 31 on both sides at the front and rear ends. Guide grooves 322 are connected on both sides of the main flow channel 321. The guide grooves 322 are inclined at a certain angle. The front and rear sides of the head of the guide groove 322 are connected to secondary flow channels 323. The secondary flow channels 323 are connected to the molding grooves 31 on both sides. The inclined guide grooves 323 facilitate the diversion of the hot melt rubber injected into the main flow channel 321 into the secondary flow channels 323, so that the molding grooves 31 can be filled with hot melt rubber faster.

[0023] Moreover, an injection port 43 is opened in the middle of the top of the upper mold base 4, and an injection diversion channel 44 is opened at the bottom of the injection port 43. A plurality of first injection channels 41 are evenly connected at the bottom of the injection diversion channel 44, and second injection channels 42 are opened on the left and right sides of the first injection channel 41. The injection diversion channel 44 facilitates the diversion of the hot melt rubber injected from the injection port 43 into each first injection channel 41, thereby injecting it into each flow channel 32.

[0024] At the same time, the bottom of the first injection channel 41 is located at the outlet on the bottom wall of the upper mold base 4, and the outlet is aligned with the center of the main flow channel 321 below. The bottom of the second injection channel 42 is located at the outlet on the bottom wall of the upper mold base 4, and the outlet is aligned with the center of the secondary flow channel 323 below. The diameter of the first injection channel 41 is larger than the diameter of the second injection channel 42. When the first injection channel 41 injects hot melt rubber into the main flow channel, the second injection channel 42 will divert a part of the hot melt rubber in the first injection channel 41, and then inject it into the secondary flow channel 323, so that the molding groove 31 is filled with hot melt rubber faster.

[0025] In this embodiment, when using a molding mold and batch injection molding automotive seals, this product can be used. First, when the upper mold base 4 and the lower mold base 3 are molded together, hot melt rubber is injected into the injection port 43 so that the hot melt rubber flows into the injection branch channel 44, and then the hot melt rubber will fill the injection branch channel 44, and then flow to the first injection channel 41 below. The hot melt rubber flows out of the first injection channel 41 into the lower channel 32. In this process, the hot melt rubber will also be diverted and flow into the second injection channels 42 on both sides. The hot melt rubber in the second injection channel 42 will flow to the secondary channel 323 below.

[0026] After the hot melt rubber flows into the main channel 321, it will flow into the molding grooves 31 on both sides. At the same time, the hot melt rubber flowing into the secondary channel 323 will also flow into the molding grooves 31 on both sides. Because the diameter of the second injection channel 42 is smaller than the diameter of the first injection channel 41, the flow rate is smaller. However, when the hot melt rubber flows in the main channel 321, the inclined guide groove 322 will divert a part of the hot melt rubber and introduce it into the secondary channel 323, so that the molding groove 31 can be filled with the hot melt rubber faster.

[0027] In the utility model, the multiple molding grooves 31 are provided so that the molding mold can perform injection molding of multiple automobile seals at one time, thereby increasing the production. At the same time, the first injection channel 41 and the second injection channel 42 provided on the upper mold base 4 facilitate the quick injection of hot melt plastic into the lower mold base 3 at one time, and the flow channel 32 provided on the lower mold base 3 facilitates the quick filling of the hot melt rubber in the molding grooves 31, thereby shortening the processing time of injection molding automobile seals and effectively improving the processing efficiency of injection molding.

[0028] 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.
