Description

Technical Field

[0001] This utility model relates to the field of demolding structure technology, specifically an adjustable auxiliary demolding structure. Background Technology

[0002] Assisted demolding structures are an important component of mold design. Through an air-pump structure, gas pressure is provided during injection molding or die casting to assist in product demolding. This structure, with its rationally designed air channels and chambers, ensures uniform gas distribution within the mold and rapid release when needed, thus facilitating smooth product ejection. During gas-assisted injection molding, the gas forms a hollow structure or cavity within the product, reducing the contact area between the product and the mold cavity, resulting in a lower demolding force compared to traditional injection molding. This promotes smooth demolding and reduces the possibility of damage or deformation during the demolding process. However, existing adjustable assisted demolding structures lack a pressure-regulating mechanism, leading to inaccurate control of the ejection force, inability to ensure smooth demolding without deformation, and inconvenient disassembly and maintenance, affecting performance. Therefore, this invention addresses these issues through in-depth research. Utility Model Content

[0022] Example 1

[0023] A preferred embodiment of the adjustable auxiliary demolding structure provided by this utility model is, for example... Figure 1 , Figure 2 and Figure 3As shown: An adjustable auxiliary demolding structure includes: a mold base 6; a control panel 10 fixedly installed on the outer wall of one side of the mold base 6, the mold base 6 having a cavity 7 inside, a lifting rod 11 installed inside the cavity 7, and a sealing top head 12 connected to the top of the lifting rod 11, a return spring 16 installed on the outer wall below the lifting rod 11, and a connector 9 connected to the bottom of the lifting rod 11; a disassembly and assembly mechanism 8 installed inside the cavity 7, the disassembly and assembly mechanism 8 being used for gas circulation and maintenance; an air pipe 5 installed inside the other side of the mold base 6, a pressure gauge 1 installed above one end of the air pipe 5; an adjustment mechanism 2 connected to one end of the air pipe 5, the adjustment mechanism 2 being used for air pressure adjustment; and an air pump 3 connected to one end of the adjustment mechanism 2, one end of the air pump 3 being connected to a filter 4.

[0024] It should be noted that the existing adjustable auxiliary demolding structure technology has the following drawbacks: it does not have a structure for adjusting air pressure, which makes it impossible to accurately control the ejection force, cannot ensure that the product can be demolded smoothly without deformation, and is inconvenient to disassemble and maintain the demolding structure, thus affecting its performance.

[0025] In this embodiment, the air pump 3 operates, and the gas is discharged upward through the vent 803. The air pressure causes the connector 9 to drive the sealing top 12 on the lifting rod 11 to move upward simultaneously. The reset spring 16 is squeezed and deformed, and the sealing top 12 pushes the mold upward against the mold part. Then the gas is discharged upward through the gap, blowing down the mold part on the outer wall of the mold base 6 to assist in demolding and prevent the mold part from deforming.

[0026] In a further preferred embodiment of the present invention, the adjusting mechanism 2 includes: a connecting pipe 201 connected to one end of the air pipe 5, a fixing plate 206 installed on the inner wall of the connecting pipe 201, a through hole 205 provided above the fixing plate 206, a baffle 204 installed on one side of the through hole 205, and a first sealing ring 207 installed on the outer wall of one side of the baffle 204.

[0027] In this embodiment, the area of ​​the through hole 205 is adjusted by rotating the baffle 204, thereby changing the air intake size of the through hole 205 and thus achieving the regulation of air pressure.

[0028] In a further preferred embodiment of the present invention, a movable rod 208 is movably installed inside the connecting pipe 201. One end of the movable rod 208 is fixedly connected to the baffle 204. A second bevel tooth 209 is installed on the outer wall of the movable rod 208, and a first bevel tooth 202 is engaged on one side above the second bevel tooth 209. A rotating rod 203 is connected to the top of the first bevel tooth 202.

[0029] In this embodiment, the first bevel gear 202 is rotated by rotating the rotating rod 203. The first bevel gear 202 meshes with the second bevel gear 209, causing the second bevel gear 209 to drive the movable rod 208 to rotate simultaneously, thereby causing the baffle 204 to rotate and adjust the blocking area of ​​the through hole 205.

[0030] In a further preferred embodiment of the present invention, an external thread 14 is provided on the outer wall above the rotating rod 203, a locking sleeve 15 is installed on the outer wall thread of the external thread 14, and an anti-slip pad 13 is connected below the locking sleeve 15.

[0031] In this embodiment, by rotating the locking sleeve 15, the threaded engagement causes the locking sleeve 15 to rotate downwards and press against the connecting pipe 201. The anti-slip pad 13 provides an anti-slip function, and the friction and pressure lock the rotating rod 203.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the adjustable auxiliary demolding structure provided by this utility model is, for example... Figure 1 , Figure 4 and Figure 5 As shown: The disassembly and assembly mechanism 8 includes: an installation block 801 installed inside the cavity 7, the installation block 801 having a vent hole 803 inside, and a second sealing ring 802 installed on the outer wall of the installation block 801 at one end of the vent hole 803.

[0034] In this embodiment, the gas enters the filter 4 for filtration by the operation of the air pump 3, and then enters the air pipe 5 through the adjustment mechanism 2. The gas is vented through the air vent 803 and the air pipe 5 through a sealed connection. The second sealing ring 802 achieves the seal between the air vent 803 and the air pipe 5.

[0035] In a further preferred embodiment of this utility model, positioning blocks 807 are connected to the outer walls of the two sides below the mounting block 801, and positioning grooves 806 that cooperate with positioning blocks 807 are provided on both sides below the cavity 7; locking blocks 805 are connected to the upper sides of the mounting block 801, and locking grooves 808 that cooperate with locking blocks 805 are provided on the inner wall of the cavity 7, and electromagnetic blocks 804 are connected to the inside of the locking grooves 808 and the top of the locking blocks 805.

[0036] In this embodiment, the magnetism disappears when the power is cut off between the opposing electromagnetic blocks 804, and then the mounting block 801 in the cavity 7 is removed downwards. The locking block 805 is moved out of the locking slot 808, and at the same time the positioning block 807 is moved out of the positioning slot 806, thus disassembling the mounting block 801.

[0037] In a further preferred embodiment of the present invention, a threaded rod 17 connected to the top of the lifting rod 11 and a threaded hole 18 are provided below the sealing head 12, forming a threaded connection structure between the lifting rod 11 and the sealing head 12.

[0038] In this embodiment, by rotating the sealing top 12, the threaded rod 17 engages with the threaded hole 18, facilitating the disassembly of the sealing top 12 and the lifting rod 11.

[0039] In summary, the pressure gauge 1 is used to check the air pressure, the adjustment mechanism 2 is used to adjust the air pressure to a suitable level, and the disassembly mechanism 8 is used for easy disassembly, thereby enabling the demolding mechanism to be inspected and repaired.
