Description

[Technical Field]

[0001] This invention relates to the field of mold mechanism technology, and in particular to a gas pipeline mechanism. [Background Technology]

[0002] When forming products, air bag molding molds typically require connecting the air bag to a high-pressure air hose. The high-pressure air hose usually needs to be inserted through the mold. Currently, the connection method used is to connect the high-pressure air hose and the air bag using a standard quick-connect coupling. First, the quick-connect coupling is snapped onto the mold. Both ends of the quick-connect coupling have connecting nozzles. One nozzle is used to connect to the high-pressure air hose, and the other nozzle is used to insert into the air bag opening. Then, a cable tie or clamp is used to seal the air bag and the nozzle, making the quick-connect coupling and the air bag sealed. However, this connection method requires repeated disassembly and reassembly of the high-pressure air hose, air bag, and quick-connect coupling before and after molding, which reduces work efficiency. Furthermore, repeated insertion and removal of the quick-connect coupling can lead to a decrease in the airtightness of the quick-connect coupling or even damage, creating safety hazards when using high-pressure gas.

[0003] In view of this, the present invention provides a gas pipeline mechanism to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is that current high-pressure air hoses for air bag forming molds typically need to be inserted through the mold and connected to the air bag using quick-connect couplings. This requires frequent disassembly and reassembly of the high-pressure air hose, quick-connect couplings, and air bag during the forming process, reducing work efficiency. Furthermore, repeated insertion and removal can lead to decreased airtightness or even damage to the quick-connect couplings, creating safety hazards when using high-pressure gas. This invention provides a gas pipeline mechanism to solve the above problems.

[0005] The solution to the technical problem of this invention is: a gas pipeline mechanism applied to an air bag forming mold, the mold including an upper mold and a lower mold, the gas pipeline mechanism including:

[0006] The first air inlet pipe is located in the upper mold. The first air inlet pipe includes a first main air inlet pipe and at least one first branch air inlet pipe. One end of the first branch air inlet pipe is connected to the first main air inlet pipe, and the other end is an air outlet. The air outlet is located on the parting surface of the upper mold.

[0007] A gas adapter block is provided on the lower mold parting surface. An air inlet is provided on the side of the gas adapter block near the upper mold. The air inlet and the air outlet are positioned correspondingly. A second air inlet pipe is provided inside the gas adapter block. One end of the second air inlet pipe is connected to the air inlet, and the other end is connected to an air nozzle. The air nozzle is fixed to the gas adapter block and is used to extend into the air bag and communicate with the air bag. A receiving groove is provided on the upper mold parting surface corresponding to the position of the gas adapter block to accommodate the gas adapter block when the mold is closed. A contoured air nozzle sealing block is provided on both the upper mold and the lower mold at the connection position between the air bag and the air nozzle.

[0008] Preferably, the upper mold side is provided with a pipe joint that communicates with the first air inlet pipe, and the pipe joint is used to connect to the air supply device.

[0009] Preferably, the gas transfer block is detachably mounted on the lower mold parting surface, and the lower mold is provided with a corresponding gas transfer block positioning groove.

[0010] Preferably, the gas transfer block is provided with a sealing ring at the air inlet to enhance the airtightness between the air outlet and the air inlet when the mold is closed.

[0011] Preferably, the air nozzle sealing block is made of elastic soft rubber and protrudes from the parting surface to press the air bag and air nozzle together when the mold is closed, thereby improving air tightness.

[0012] Preferably, the upper mold is provided with an air inlet pipe plug, which is located at a corresponding position on the first main air inlet pipe and between each of the first branch air inlet pipes. The air inlet pipe plug is used to extend and retract relative to the first main air inlet pipe, thereby blocking or opening the first main air inlet pipe and controlling the gas flow direction.

[0013] Preferably, the intake pipe plug includes, but is not limited to, a screw.

[0014] The beneficial effects of this invention are that the gas pipeline mechanism of this invention eliminates the need for repeated disassembly and assembly of high-pressure gas pipes, quick-connect fittings, and gas bags during the product molding process of the gas bag forming mold, thereby improving work efficiency. The high-pressure gas is conducted through the built-in gas pipeline, and the gas transfer block and the gas nozzle sealing blocks on both sides of the connection between the gas bag and the gas nozzle are pressed by the mold closing force to improve airtightness, ensuring the safety of high-pressure gas operations. The structure is simple and easy to install and maintain. [Attached Image Description]

Detailed Implementation Methods

[0020] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the embodiments of the present invention and their accompanying drawings.

[0021] This invention provides a gas pipeline mechanism applied to an air bag forming mold, the mold comprising an upper mold 1 and a lower mold 2, the gas pipeline mechanism comprising:

[0022] The first air intake pipe 10 is disposed in the upper mold 1. The upper mold 1 has a pipe connector 11 on its side that communicates with the first air intake pipe 10. The pipe connector 11 is used to connect with the air supply device. The first air intake pipe 10 includes a first main air intake pipe 100 and at least one first branch air intake pipe 101. One end of the first branch air intake pipe 101 is connected to the first main air intake pipe 100, and the other end is an air outlet 102. The air outlet 102 is disposed on the parting surface of the upper mold 1.

[0023] A gas adapter block 3 is detachably mounted on the parting surface of the lower mold 2. The lower mold 2 has a corresponding gas adapter block positioning groove. An air inlet 33 is located on the side of the gas adapter block 3 closest to the upper mold 1, and the air inlet 33 is positioned corresponding to the air outlet 102. A second air inlet pipe (not shown in the figure) is provided inside the gas adapter block 3. One end of the second air inlet pipe is connected to the air inlet 33, and the other end is connected to an air nozzle 31. The air nozzle 31 is fixed to the gas adapter block. On block 3, the air nozzle 31 is used to extend into the air bag 4 and communicate with the air bag 4. The upper mold 1 has a receiving groove 12 on the parting surface corresponding to the position of the gas transfer block 3, which is used to receive the gas transfer block 3 when the mold is closed. The upper mold 1 and the lower mold 2 are both provided with a contoured air nozzle sealing block 5 at the connection position between the air bag 4 and the air nozzle 31. The air nozzle sealing block 5 is made of elastic soft rubber and is set slightly protruding from the parting surface, which is used to press the connection position between the air bag 4 and the air nozzle 31 when the mold is closed, thereby improving the air tightness.

[0024] The upper mold 1 is provided with an air inlet pipe plug 13, which is located at a corresponding position on the first main air inlet pipe 100 and between each of the first branch air inlet pipes 101. The air inlet pipe plug 13 can be extended and retracted relative to the first main air inlet pipe 100. When the air inlet pipe plug 13 is adjusted so that its end away from the lower mold 2 is fully inserted into the first main air inlet pipe 100, the first main air inlet pipe 100 is blocked and closed by the air inlet pipe plug 13. The air inlet pipe plug 13 is used to block or open the first main air inlet pipe 100 to control the gas flow direction. The air inlet pipe plug 13 includes, but is not limited to, a screw.

[0025] The gas transfer block 3 is provided with a sealing ring 30 at the air inlet 33 to enhance the airtightness between the air outlet 102 and the air inlet 33 when the mold is closed.

[0026] The working process of this invention is as follows: First, connect the pipeline connector 11 to the gas supply device. Then, place the air bag 4 in the cavity of the lower mold 2 and insert the air nozzle 31 on the gas adapter block 3 into the air bag 4. Next, close the mold. The air outlet 102 on the upper mold 1 is aligned and connected with the air inlet 33 on the gas adapter block 3. Under the action of the mold closing force and the sealing ring 30, the air bag 4 and the air nozzle 31 are sealed by the air nozzle sealing block 5. When the molding conditions are met, start the gas supply device. High-pressure gas passes through the first air inlet pipeline 10 and the second air inlet pipeline in sequence and then enters the air bag 4 through the air nozzle 31 to assist in product molding. After the product is molded, turn off the gas supply device, open the mold and take out the product.

[0027] The beneficial effects of this invention are that by setting a gas pipeline mechanism inside the gas bag forming mold, the high-pressure gas pipe, quick connector, and gas bag 4 are eliminated from repeated disassembly and assembly during the product forming process, thus improving work efficiency. The high-pressure gas is conducted through the built-in gas pipeline, and the gas transfer block 3 and the gas nozzle sealing blocks 5 on both sides of the connection between the gas bag 4 and the gas nozzle 31 are pressed by the mold closing force to improve air tightness, ensuring the safety of high-pressure gas operation. The structure is simple and easy to install and maintain.

[0028] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical solutions of the present invention shall fall within the protection scope of the present invention.
