Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a quick-detachable breathable steel structure for improving air entrapment. Background Art

[0002] Air entrapment in mold means that the gas in the mold cavity cannot be discharged from the injection mold in time or cannot be discharged from the injection mold during the process of filling the mold cavity with injection, thereby preventing the rubber from continuing to fill, resulting in injection defects such as material shortage and burning. Air entrapment usually occurs in the process of filling the mold cavity. There are two main sources of air entrapment: one is the original air in the mold cavity; the other is the decomposition gas and a small amount of water vapor that may be generated by the rubber during the heating process.

[0003] At present, traditional molds solve the problem of trapped air by making exhaust grooves when in use. However, this method has the disadvantage that the space on the mold is small and the space for trapped air on the product is limited, resulting in low exhaust efficiency. Moreover, after long-term use, the mold needs to be replaced and maintained, which takes a long time and affects production efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a quick-detachable breathable steel structure for improving air trapping, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a quick-release breathable steel structure for improving air trapping, including an upper mold cover, a mounting groove is provided on the surface of the upper mold cover, a mold core is provided inside the mounting groove, a T-slot insert is installed on the surface of the mold core by screws, an exhaust insert made of breathable steel is slidably arranged on the T-slot insert through a T-slot, an exhaust hole is provided on the surface of the T-slot insert, and exhaust channels are provided inside the upper mold cover and the mold core.

[0006] Optionally, the surface of the mold core is further provided with an insert groove for installing the exhaust insert.

[0007] Optionally, the size of the T-slot matches the size of the T-slot insert.

[0008] Optionally, a sealing rubber ring is provided at the joint between the upper mold cover and the exhaust channel on the mold core.

[0009] Optionally, the exhaust insert has a thickness of 12 mm, and a groove is provided on the surface of the T-slot insert.

[0010] Optionally, an exhaust port is provided on one side of the upper mold cover corresponding to the exhaust channel.

[0011] The utility model provides a quick-detachable breathable steel structure for improving air entrapment, which has the following beneficial effects:

[0012] 1. The quick-detachable breathable steel structure that improves air entrapment expands the exhaust area of the mold by adopting the exhaust insert made of breathable steel, effectively improving the exhaust efficiency and improving the air entrapment situation. At the same time, the 12mm thickness is set to shorten the distance that the gas passes through the exhaust insert in the mold as much as possible, further improving the exhaust effect. The exhaust insert is installed by sliding through the T-slot and T-slot insert on the exhaust insert, which facilitates the quick disassembly and replacement of the exhaust insert, effectively shortening the maintenance time of the mold.

[0013] 2. The quick-detachable breathable steel structure that improves air entrapment has an insert groove that blocks both ends of the exhaust insert to prevent it from moving after installation. The sealing rubber ring is set to seal the joint of the exhaust channel to effectively prevent air leakage. The groove on the T-slot insert is set to enable the exhaust channel to absorb the gas inside the mold better and more efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the insert groove 10, after the exhaust insert 5 is installed, the two ends of the exhaust insert 5 are blocked and fixed to prevent it from moving. A T-slot insert 7 is installed on the surface of the mold core 3 by screws 4. The exhaust insert 5 made of breathable steel is slidably arranged on the T-slot insert 7 through the T-slot 6. The thickness of the exhaust insert 5 is 12 mm. The setting of the gas insert 5 is used to expand the exhaust area of the mold, effectively improve the exhaust efficiency, and improve the air entrapment situation. At the same time, the setting of the 12mm thickness is used to shorten the distance that the gas passes through the exhaust insert 5 in the mold as much as possible, further improving the exhaust effect. The surface of the T-slot insert 7 is provided with a groove 12. The setting of the groove 12 on the T-slot insert 7 enables the exhaust channel 9 to better and more efficiently absorb the gas inside the mold. The size of the T-slot 6 is adapted to the size of the T-slot insert 7. The T-slot 6 and the T-slot insert 7 on the exhaust insert 5 are matched and the exhaust insert 5 is slidably installed to facilitate the quick disassembly and replacement of the exhaust insert 5, effectively shortening the time for maintaining the mold.

A sealing rubber ring 11 is provided at the joint of the exhaust channel 9 on the upper mold cover 1 and the mold core 3. The sealing rubber ring 11 is provided to seal the joint of the exhaust channel 9 to effectively prevent air leakage. An exhaust port 13 is provided on one side of the upper mold cover 1 corresponding to the exhaust channel 9 to quickly exhaust the air by connecting the exhaust component through the exhaust port 13.

[0023] In the present invention, the working steps of the device are as follows:

[0024] First, assemble the exhaust insert 5 onto the T-slot insert 7, and then fix it into the insert groove 10 of the mold core 3 with screws 4. Then, place the sealing rubber ring 11 at the joint of the exhaust channel 9, and install the mold core 3 into the installation groove 2 of the upper mold cover 1 with bolts.

[0025] Then install the upper mold cover 1 on the injection molding machine and connect it to the exhaust assembly through the exhaust port 13;

[0026] During injection molding, the exhaust assembly starts exhausting, and the gas inside the mold passes through the exhaust insert 5 and enters the exhaust channel 9 from the exhaust hole 8 of the T-slot insert 7 for exhaust.
