The second jig has a second bearing surface, and the second jig can be buckled with the first jig so that the second bearing surface fits the first bearing surface and limits the position of the product placed in the product placement area. The cooling and shaping jig of the utility model adopts a cooling copper tube and a coolant to work, which can achieve the effect of rapidly reducing the temperature of the jig body, thereby rapidly cooling the products placed in the product placement area, improving production efficiency, and reducing working hours and manpower.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1 and Figure 2 and Figure 3 As shown, the internal cooling device of the aluminum alloy fixture includes a frame 1, a cooling circulation mechanism, a fixture 2 and a composite cooling mechanism. The fixture 2 is fixedly connected to the frame 1, the composite cooling mechanism is connected to the frame 1 and is located at the fixture 2 in the initial state, the cooling circulation mechanism is located at the side of the frame 1 and is connected to the composite cooling mechanism through a connecting pipe, the cooling medium in the cooling circulation mechanism can circulate in the composite cooling mechanism through the connecting pipe, and the composite cooling mechanism can move up and detach from the fixture 2 when in a non-cooling state.

[0031] The device creatively arranges a composite cooling mechanism that can move up and down at the fixture 2. In the initial state, the composite cooling mechanism is located at the fixture 2. When the cooling circulation mechanism is in operation, the temperature at the fixture 2 can be stably and effectively reduced.

[0032] Of course, when cooling treatment is not required, the composite cooling mechanism can be moved upward and separated from the fixture 2.

[0033] The composite cooling mechanism includes a driving member 3, a cooling plate 1 4, a cooling plate 2 5 and a cooling frame 6. The cooling plate 1 4 and the cooling plate 2 5 are both in the shape of a flat plate. The cooling plate 1 4 and the cooling plate 2 5 have cooling channels for the cooling medium to pass through. The cooling frame 6 is frame-shaped and has cooling channels for the cooling medium to pass through. The cooling frame 6 is connected to the upper part of the cooling plate 1 4. The cooling plate 2 5 is connected in the cooling frame 6 and the cooling plate 2 5 is located at the upper part of the cooling plate 1 4. The cooling plate 1 4, the cooling plate 2 5 and the cooling frame 6 form a cooling unit. The driving member 3 is fixedly connected to the upper part of the frame 1 and the driving member 3 is connected to the cooling unit.

[0034] The fixture 2 is in the shape of a flat plate and has a protruding convex edge at its upper edge. The protruding convex edge forms a shallow concave cavity structure with an upper opening on the upper part of the fixture 2.

[0035] The cooling plate 1 4 is used to cool the bottom of the fixture 2, the cooling plate 2 5 is used to cool the upper part of the fixture 2, and the cooling frame 6 is used to cool the edge of the fixture 2. It can be seen that under the action of the cooling plate 1 4, the cooling plate 2 5 and the cooling frame 6, various parts of the fixture 2 can be stably cooled.

[0036] The cooling plate 1 4 is flush with the outer edge of the cooling frame 6 .

[0037] This can appropriately improve the structural compactness of the device.

[0038] The jig 2 has a sensor capable of detecting the temperature of the sensor.

[0039] The sensor is a thermocouple sensor.

[0040] The temperature sensor can accurately and timely detect the real-time temperature of the fixture.

[0041] The cooling circulation mechanism comprises a cooling pool and a temperature regulator located in the cooling pool.

[0042] The connecting pipes include a circulation pipe 1 7, a circulation pipe 2 8 and a circulation pipe 3 9. The circulation pipe 1 7 connects the cooling channel in the cooling plate 1 4 with the cooling pool 10, the circulation pipe 2 8 connects the cooling channel in the cooling plate 2 5 with the cooling pool 10, and the circulation pipe 3 9 connects the cooling channel in the cooling frame 6 with the cooling pool 10.

[0043] The cooling pool 10 has an inlet and an outlet connected to its inner cavity, and one end interface of the circulation pipe 1 7, the circulation pipe 2 8, and the circulation pipe 3 9 is connected to the inlet, and the other end interface of the circulation pipe 1 7, the circulation pipe 2 8, and the circulation pipe 3 9 is connected to the outlet.

[0044] The end interfaces of circulation pipe 1 7 , circulation pipe 2 8 and circulation pipe 3 9 are all connected to the inlet and outlet of the cooling pool 10 , which can improve the structure and commitment and avoid opening too many hole structures in the cooling pool 10 .

[0045] The temperature regulator is a water chiller having a cooling tower and connected to a cooling pool.

[0046] The chiller with a cooling tower is a prior art, and therefore, its specific technical solution will not be described in detail in this embodiment.

[0047] The frame 1 has a guide rail 11, and the guide rail 11 is connected to a bracket 12 that can translate along the guide rail. The above-mentioned fixture 2 and the composite cooling mechanism are both connected to the bracket 12. The frame 1 is also fixedly connected to a cylinder 13, and the cylinder body of the cylinder 13 is connected to the bracket 12 and the piston rod of the cylinder 13 is fixedly connected to the bracket 12.

[0048] After the cylinder 13 drives the bracket 12 to move, the entire fixture 2 and the corresponding composite cooling mechanism can be translated, thereby appropriately improving its applicability.

[0049] In the internal cooling device of the aluminum alloy fixture, since the composite cooling mechanism can cool the fixture at a set temperature, the cooling effect is relatively good and the fixture will not be damaged due to excessive temperature difference.

[0050] Water passes through the circulation equipment to cool the fixture template, and the water temperature can be adjusted to control the product to achieve different cooling rates.

[0051] The fixture structure can be divided into three types of cooling structures according to the product shape, and layered cooling is performed on different contact surfaces of the product to achieve uniform overall cooling.

[0052] The temperature-controlled press senses the temperature inside the fixture through thermocouples and flexibly adjusts the temperature of the cooling system to meet the requirements of different cooling rates in different structural areas of the product.

[0053] In other words, the aluminum alloy fixture has good cooling effect and high stability.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
