[0005] The output end of the electric telescopic rod is fixedly connected to a placement plate, and a locking assembly is provided on the upper surface of the placement plate. The locking assembly includes a clamping plate slidably arranged on the upper surface of the placement plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the die-casting machine shot head quenching heat treatment device adopts a new structural design, and its specific contents are as follows:

[0014] (1) During the use of the die-casting machine shot head quenching heat treatment device, the workpiece is first placed on the placement plate. At this time, the workpiece will push the clamping plate through the transition plate, causing the clamping plate to move in the direction of squeezing the connecting spring. Then, under the action of the connecting spring and the long pin, the clamping plate has a tendency to always move to the middle position of the placement plate. Then, the clamping plate can support the workpiece, so that the workpiece will not fall during the processing, thereby ensuring stability.

[0015] Furthermore, during the movement of the clamping plate, the long pin causes the clamping plate to move only in the horizontal direction, thereby ensuring stability. At the same time, the baffle at the end of the long pin limits the movement distance of the clamping plate, and the clamping plate will not fall.

[0016] (2) In the quenching heat treatment device for the die-casting machine shot head, after the workpiece is fixed, the electric telescopic rod drives the placement plate to descend so that the quenching liquid submerges the workpiece. During the descending process of the placement plate, the torsion spring loses the tension of the traction rope. At this time, the connecting shaft rotates under the action of the torsion spring, and then the connecting shaft and the mixing blade can shake the quenching liquid, so that the heat inside the quenching liquid can be quickly dissipated, which is convenient for the long-term use of the quenching liquid.

[0017] Furthermore, during the shaking of the quenching liquid, impurities will not settle, and scale crystallization will not occur, which will prevent the shell from being corroded, thereby extending the service life of the shell.

[0018] (3) In the die-casting machine shot head quenching heat treatment device, when the connecting shaft rotates, the connecting shaft drives the inner rod to rotate inside the outer shell through the main gear and the auxiliary gear. At this time, the inner rod and the auxiliary plate also play a role in assisting shaking and heat dissipation, optimizing the cooling effect of the quenching liquid, and the gasket prevents the outer shell from leaking.

[0027] The present invention provides the following technical solution: a die-casting machine die-casting head quenching heat treatment device:

[0028] Embodiment 1: By setting the clamping plate 7, the workpiece can be clamped quickly, such as Figure 1-Figure 3 As shown, it includes a shell 1, the front and rear side surfaces of the shell 1 are convex, and the upper surface of the convex position of the shell 1 is fixedly connected to a connecting plate 2, and the lower surface of the connecting plate 2 is bolted to an electric telescopic rod 4; the output end of the electric telescopic rod 4 is fixedly connected to a placement plate 3, and the upper surface of the placement plate 3 is provided with a locking assembly, and the locking assembly includes a clamping plate 7 slidably arranged on the upper surface of the placement plate 3. When the locking assembly is working, the workpiece to be quenched is clamped and fixed by the clamping plate 7;

[0029] The locking assembly also includes a vertical plate 5 fixedly connected to the upper surface of the placement plate 3, and the vertical plates 5 are symmetrically distributed on both sides of the upper surface of the placement plate 3, and a long pin 6 is fixedly connected to the surface of the vertical plate 5, the long pin 6 passes through the interior of the clamping plate 7, and the long pin 6 and the clamping plate 7 are slidably connected, and a baffle 10 is fixedly connected to the end of the long pin 6, and a connecting spring 9 that plays an elastic reset role is fixedly connected to the surface of the clamping plate 7, and the other side of the connecting spring 9 is fixedly connected to the surface of the vertical plate 5, and a transition plate 8 is fixedly connected to the surface of the clamping plate 7, and the surface of the transition plate 8 is inclined.

[0030] During use, the workpiece is first placed on the placement plate 3. At this time, the workpiece will push the clamping plate 7 through the transition plate 8, causing the clamping plate 7 to move in the direction of squeezing the connecting spring 9. Then, under the action of the connecting spring 9 and the long pin 6, the clamping plate 7 always tends to move toward the middle position of the placement plate 3. Then, the clamping plate 7 can support the workpiece, so that the workpiece will not fall during the processing, thereby ensuring stability. During the movement of the clamping plate 7, the long pin 6 makes the clamping plate 7 move only in the horizontal direction, thereby ensuring stability. At the same time, the baffle 10 at the end of the long pin 6 limits the movement distance of the clamping plate 7, and the clamping plate 7 will not fall.

[0031] Embodiment 2: Different from Embodiment 1, the quenching liquid can be shaken by the connecting shaft 11 and the mixing blade 15, so that the heat of the quenching liquid can be quickly discharged. Figure 4-Figure 6As shown, a connecting shaft 11 is rotatably provided inside the outer shell 1, and a mixing blade 15 is fixedly connected to the surface of the connecting shaft 11, and an inner rod 13 is rotatably provided inside the outer shell 1, and an auxiliary plate 19 is fixedly connected to the surface of the inner rod 13, a traction rope 16 is fixedly connected to the lower surface of the placement plate 3, and the other side of the traction rope 16 is wound and fixedly connected to the surface of the connecting shaft 11, and a partition 17 is fixedly connected to the surface of the connecting shaft 11.

[0033] After the workpiece is clamped, the electric telescopic rod 4 on the lower surface of the connecting plate 2 drives the placement plate 3 to descend, and finally the workpiece is submerged in the quenching liquid. When the placement plate 3 descends, the connecting shaft 11 loses the pulling force of the traction rope 16. At this time, the connecting shaft 11 rotates under the action of the torsion spring 18, and then the connecting shaft 11 drives the mixing blades 15 to shake the quenching liquid, so that the heat of the quenching liquid is quickly dissipated, and the quenching liquid and the shell 1 are quickly cooled down, which is convenient for the long-term use of the quenching liquid.

[0034] Embodiment 3: Different from Embodiment 2, the inner rod 13 and the auxiliary sheet 19 are provided to assist heat dissipation.

When the inner rod 13 rotates, the auxiliary plate 19 rotates, so that the quenching liquid can be cooled more quickly. In addition, during the shaking process of the quenching liquid, impurities will not be precipitated, and scale nodules will not be formed, and the outer shell 1 will not be corroded, thereby extending the service life of the outer shell 1.

[0036] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
