Technical Field

[0001] The utility model belongs to the technical field of mold design, and particularly relates to an anti-adhesion aluminum mold. Background Art

[0002] Aluminum mold adhesion is a common problem, usually caused by excessive mold temperature or excessive adhesion between the aluminum and the mold. In order to solve this problem, the current anti-adhesion measures for existing molds are mostly to add cooling systems, apply mold release agents, and apply anti-adhesion agents. However, for more complex mold molding surfaces, it is difficult to cool multiple molding surfaces at the same time, and it is difficult to control the uniformity of the application of mold release agents and anti-adhesion agents, resulting in the continued existence of adhesion problems.

[0038] See also Figure 1 and Figure 5 As shown, an anti-adhesion aluminum mold is characterized by comprising: a mold base 1; a lower mold 2, which is fixedly mounted on the upper end surface of the mold base 1 by using multiple studs, and a first anti-adhesion mechanism 3 is symmetrically arranged in the lower mold 2; a sliding connection column 4, which is fixedly connected to an external hydraulic device; a mold top seat 5, which is fixed to the lower end surface of the sliding connection column 4; and an upper mold 6, which is arranged below the mold top seat 5, and a second anti-adhesion mechanism 7 is arranged in the upper mold 6;

[0039] Wherein, the first anti-adhesion mechanism 3 comprises:

[0040] The first cavity 31 is in a truncated cone shape. The first cavity 31 is opened in the lower mold 2. The two first cavities 31 are close to each other and a first cylindrical cavity is opened at one end;

[0041] A plug 32 is sealed and fixed in the first chamber 31 at a side away from each other;

[0042] A guide rod 33, one end of which is sealed and slidably disposed in a plug 32, and the other end of which is fixedly connected to a slide column 34, which is sealed and slidably disposed in the first cylindrical chamber;

[0043] A lifting block 35 is fixed to an end of a guide rod 33 close to a plug 32;

[0044] A spring 36 connected between the slide post 34 and the plug 32; and

[0045] A flow channel 37, one end of which is connected to the outside of the lower mold 2, and the other end of which is connected to the first cavity 31;

[0046] The second anti-adhesion mechanism 7 comprises:

[0047] The connecting cavity 71 is columnar and vertically opened in the central part of the upper end of the upper mold 6;

[0048] The second chamber 72 is symmetrically arranged inside the upper mold 6, and the second chamber 72 is truncated cone-shaped, and the large diameter ends of the two second chambers 72 are connected to the connecting chamber 71, and the two second chambers 72 are separated from each other by one end and a second cylindrical chamber is opened;

[0049] The second plug 73 is sealed and fixed in the second chamber 72 on one side close to each other;

[0050] A second guide rod 74 has one end sealed and slidably disposed in the second plug 73, and the other end is fixedly connected to a second slide post 75, which is sealed and slidably disposed in the second cylindrical chamber;

[0051] The second spring 76 is connected between the second sliding post 75 and the second plug 73;

[0052] A guide rod 3 77 is slidably disposed in the connection cavity 71, the lower end of the guide rod 3 77 is connected to the two guide rods 2 74 by a lifting rope 78, and a lifting block 2 79 is fixedly connected to the top of the guide rod 3 77; and

[0053] The second flow channel 80 is provided with two ends, one end of which is connected to the outside of the upper mold 6 and the other end of which is connected to the second cavity 72 .

[0054] When the workpiece needs to be demoulded, the device can be used for operation. First, the lifting block 35 is pulled until the slide column 34 completely slides out of the first cylindrical chamber, so that the first chamber 31 and the molded workpiece form a connecting body. At this time, the fluorocarbon agent is injected from the drainage channel 37, and then the lifting block 35 is released. Under the action of the spring 36, the slide column 34 performs a reset action, and the pressure generated can push the fluorocarbon agent into the gap between the workpiece and the lower mold 2, thereby reducing the adhesion between the lower mold 2 and the aluminum workpiece; and, because the energy of the spring 36 is not completely released, the slide column 34 will collide with the workpiece after resetting, thereby increasing the gap between the lower mold 2 and the workpiece. On the one hand, the continuous micro-vibration generated by this collision can reduce the binding energy between the aluminum workpiece and the mold, thereby reducing the adhesion. On the other hand, the fluorocarbon agent can quickly penetrate downward under the action of gravity, increasing the penetration area of ​​the fluorocarbon agent, thereby preventing adhesion between the lower mold 2 and the aluminum workpiece.

[0055] Subsequently, the anti-adhesion treatment method for demolding the aluminum workpiece and the upper mold 6 is the same as the above principle, specifically: first pull the lifting block 2 79 and introduce the fluorocarbon agent into the second chamber 72 through the drainage channel 2 80. After releasing the lifting block 2 79, the sliding column 2 75 pushes the fluorocarbon agent into the gap between the upper mold 6 and the aluminum workpiece, and then intermittently pulls the lifting block 2 79 to increase the gap area. Under the action of gravity, the fluorocarbon agent quickly penetrates downward, increasing the effective area of ​​the fluorocarbon agent and improving the anti-adhesion effect.

[0056] like Figures 1 to 5 As shown, an elastic column 81 is connected between the lifting block 2 79 and the upper mold 6, so that the lifting block 2 79 can move downward synchronously with the guide rod 3 77, the end face shape of the sliding column 1 34 on one side close to each other is consistent with the shape missing in the first cylindrical cavity of the lower mold 2, and the end face shape of the sliding column 2 75 on one side away from each other is consistent with the shape missing in the second cylindrical cavity, and scale lines are provided on the guide rod 1 33 and the guide rod 3 77 to facilitate controlling the pulling distance. A plurality of columns 8 are fixedly installed between the upper mold 6 and the mold top seat 5 to create space for pulling the lifting block 2 79, and a balancing block is provided at the lower end of the guide rod 3 77. The balancing block is sealingly slidably arranged in the connecting cavity 71, and the balancing block can make the two guide rods 2 74 move synchronously. A positioning pin 9 can be assembled on the lower end face of the upper mold 6, and a positioning hole 10 cooperating with the positioning pin 9 is opened on the upper end face of the lower mold 2. A switch valve is provided at the connection between the drainage channel 1 37 and the drainage channel 2 80 and the external injection device.

[0057] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
