when the positioning plate 3 is rotated to the position corresponding to the limiting hole 7, the two positioning plates 3 move towards the direction away from each other and are inserted into the limiting hole 7 under the action of the positioning spring 4 (when the limiting hole 7 is arranged, the width of the limiting hole 7 is enabled to be larger than that of the limiting hole 7) The width of the positioning plate 3 is kept the same), and the upper die 1 and the lower die 2 are connected in a positioning way at the moment;

when the upper die 1 and the lower die 2 need to be separated, the positioning plate 3 is pressed towards the position close to the center of the upper die 1 by abutting a tool against the head of the positioning plate 3 so that the positioning plate 3 is completely withdrawn from the limiting hole 7, at the moment, the upper die 1 or the lower die 2 is rotated for 90 degrees (so that the positioning plate 3 corresponds to the alignment hole 5), and then the upper die 1 or the lower die 2 is pulled outwards to separate the dies, so that the operation is simple and convenient, and the workload of operation maintenance personnel is reduced;

as shown in the attached figure 5, a first cavity 8 and a second cavity 9 are coaxially arranged in the lower die 2 at intervals along the radial direction, a first radiating pipe 10 is arranged in the first cavity 8, a second radiating pipe 11 is arranged in the second cavity 9 (the radiating pipes are all spirally arranged in the corresponding cavities), the upper ends of the first radiating pipe 10 and the second radiating pipe 11 are communicated with a valve cavity fixed on the side wall of the lower die 2, and the valve cavity is communicated with a pressure stabilizing water source (initially, a switch plate in the valve cavity is in a closed state and no water flows exist in the radiating pipes), when the temperature in the die is too high and cooling and radiating are needed, the switch plate is controlled by a channel control device to act, so that the second radiating pipe 11 is communicated with the valve cavity, at the moment, the pressure stabilizing water source starts to convey water flows into the second radiating pipe 11 to cool and radiate the heat in the die, and the bottom of the lower die 2 is provided with the first radiating pipe 10, The water outlet pipe 28 (as shown in fig. 6) connected to the second heat dissipating pipe 11, the water flowing into the heat dissipating pipe through the valve cavity is discharged outwards through the water outlet pipe 28, so as to achieve the effect of taking away the heat in the mold;

Embodiment 2, on the basis of embodiment 1, as shown in fig. 7, the valve cavity includes an L-shaped pipe 12 fixedly installed on a side wall of the lower die 2 away from the upper die 1, the switch board includes valve boards 13 vertically and rotatably installed in the L-shaped pipe 12, initially, the two valve boards 13 are in a state as shown in fig. 7, at this time, no water flows exist in the first radiating pipe 10 and the second radiating pipe 11, and water from a pressure-stabilizing water source cannot be delivered into the two radiating pipes, if the temperature in the die exceeds a required range, the driving device will first drive the control rod 16 located below to move (i.e., drive the control rod 16 to move outward), the driving rod 16 drives the driving rod 14 to rotate through the connecting rod 15 along with the movement of the control rod 16, and the driving plate 14 rotates along with the rotation of the driving plate, so that the driving plate 13 corresponding to the driving plate is synchronously driven to rotate (so that the valve boards 13 slowly rotate from an initial horizontal state to a vertical state), until the valve plate 13 at the lower part rotates to the state shown in fig. 9, the driving device stops driving the valve plate 13 (only the second heat dissipation pipe 11 in the mold is filled with water, and the single channel cools and dissipates heat), if the temperature in the mold is still rising, the driving device starts to drive the control rod 16 at the upper part to move outwards (the position of the control rod 16 at the lower part is kept still, that is, the valve plate 13 at the lower part is always in the state shown in fig. 9), and along with the continuous rising of the temperature, the driving device gradually drives the control rod 16 at the upper part to slide outwards so as to rotate the valve plate 13 at the upper part to the vertical state through the driving plate 14 of the connecting rod 15 matched with the temperature, at the same time, the first heat dissipation pipe 10 and the second heat dissipation pipe 11 are filled with water, and the mold is cooled and dissipated heat (the double channel cools and dissipates heat) at the same time, Heat dissipation), the mold can be cooled and dissipated more quickly;

if the temperature in the mould drops, the drive means will first remove the force applied to the control rod 16 located above and cause the corresponding drive plate 14 to rotate towards the initial position under the action of the torsion spring 29, so that when the valve plate 13 located above rotates to the initial position (as shown in fig. 9), no water flows through the first heat dissipation pipe 10, and only the second heat dissipation pipe 11 is left to cool and dissipate heat for the mold, if the temperature in the mold continues to decrease, the drive means will gradually remove the force applied to the control rod 16 located below and cause the corresponding drive plate 14 to rotate towards the initial condition under the action of the torsion spring 29, when the temperature in the mold is restored to the normal range, the valve plate 13 located below rotates to the initial position shown in fig. 7, and the two heat pipes stop radiating heat to the mold.

Embodiment 3, on the basis of embodiment 2, as shown in fig. 7, an abutting rod 17 is vertically slidably mounted on a control rod 16 located below, and an abutting spring 18 is connected between the abutting rod 17 and the control rod 16 (initially, the upper end of the abutting rod 17 under the action of the abutting spring 18 is located on a plane higher than the upper end surface of the control rod 16), an arc plate 19 is integrally arranged at the lower end of the abutting rod 17, and a protruding plate 20 matched with the arc plate 19 is fixed on the lower die 2 (initially, the protruding plate 20 is not in contact with the arc plate 19), when the temperature in the die is higher than a normal required range, a power control device drives a driving rod 30 to move outwards (initially, the driving rod 30 abuts against the side wall of the abutting rod 17 at the outer end of the lower die 2), the control rod 16 located below is driven to move synchronously by abutting against the side wall of the abutting rod 17 along with the movement of the driving rod 30, and a valve plate 13 located below is rotated along with the movement of the control rod 16, so as to drive the vertical abutting rod 17 slidably mounted on the control rod 16 located below to move to the arc plate 19 and the arc surface of the convex plate 20, the abutting rod 17 is forced to move downwards (so that the abutting spring 18 is stretched) under the action of the convex plate 20, so that when the upper end of the abutting rod 17 is flush with the upper end surface of the control rod 16 (at this time, the highest point of the arc plate 19 is just matched with the lowest point of the convex plate 20, and the valve plate 13 located below is just rotated to the state shown in fig. 9), the gear 21 and the tooth system 22 arranged on the driving rod 30 are always in a meshed state in the above process, and the expansion spring 33 connected between the gear 21 and the control rod 16 is in a natural state (the gear 21 is fixedly mounted on the slider 32 slidably mounted on the control rod 16, and the expansion spring 33 is connected between the slider 32 and the control rod 16);

if the temperature in the mold continues to rise, the power control device continues to drive the driving rod 30 to move outward, and then the driving rod 30 starts to drive the control rod 16 located above to move and rotate the valve plate 13 located above from the initial horizontal position to the vertical position, at this time, the control rods 16 located below cannot move outwards continuously (as shown in fig. 8, a blocking rod 31 is arranged at one end of each of the two control rods 16 located in the lower mold 2, so that when the valve plate 13 located below rotates by 90 °, the control rods 16 just drive the blocking rods 31 to move to positions abutting against the side walls of the lower mold 2, and at this time, the control rods 16 cannot move outwards continuously), and then the gear 21 is driven to slide along the control rod 16 corresponding to the gear 21 through the meshing between the gear 21 and the gear system 22 along with the continuous movement of the driving rod 30, so that the telescopic springs 33 are stretched;

if the temperature in the mold continues to rise, the power control device drives the driving rod 30 to continue to move outwards so as to enable the valve plate 13 located above to rotate to the vertical state (at this time, the control rod 16 located above is just driven to move to enable the blocking rod 31 fixedly installed with the control rod to be abutted to the inner wall of the lower mold 2, and the control rod 16 cannot continue to move outwards), and at this time, the heat is dissipated through double channels.

Embodiment 4, on the basis of embodiment 3, as shown in fig. 8, the power control device includes an iron sheet 23 installed on the drive board 14 in the lower die 2, and an electromagnet 24 corresponding to the iron sheet 23 is installed on the inner wall of the lower die 2 (the installation portion of the electromagnet 24 and the inner wall of the lower die 2 is provided with an insulating heat-insulating pad and the electromagnet 24 is installed on the insulating heat-insulating pad, so as to prevent the heat of the die body from being transferred to the electromagnet 24 and affecting the work thereof), the electromagnet 24 is connected in series in an external voltage stabilizing loop via a wire (a wire hole is formed on the side wall of the lower die 2, not shown in the figure), a thermistor is installed in the lower die 2 and connected in series in the voltage stabilizing loop (the thermistor is electrically connected to the external voltage stabilizing loop via the wire hole), during the extrusion molding of the heated aluminum material, the temperature in the die gradually rises, and the resistance of the thermistor connected in the voltage stabilizing loop gradually decreases (the thermistor gradually decreases as the ambient temperature increases) ) At this time, the current in the voltage stabilizing circuit is gradually increased, and the magnetic force of the electromagnet 24 is gradually increased (so that the electromagnetic force is enough to overcome the acting force of the torsion spring 29 on the driving plate 14 through the adsorption iron sheet 23);

when the mold is started to be cooled, a person skilled in the art determines and selects a corresponding thermistor and a corresponding torsion spring 29 according to the proper temperature of the mold during working when setting, so that when the temperature in the mold is higher than the proper working temperature range, the electromagnetic force generated by the electromagnet 24 can drive the driving rod 30 to move outwards by adsorbing the iron sheet 23;

the driving rod 30 moves outwards, the abutting rod 17 abutting against the driving rod drives the control rod 16 located below to move, the resistance value of the thermistor is gradually reduced along with the increase of the temperature in the mold, the electromagnetic force generated by the electromagnet 24 is gradually increased, the driving rod 30 can be driven to move outwards through the adsorption iron sheet 23, if the temperature in the mold begins to decrease, the resistance value of the thermistor is gradually increased, the electromagnetic force generated by the electromagnet 24 is gradually decreased, the electromagnetic force at the moment is not enough to overcome the acting force of the torsion spring 29 on the driving plate 14, the driving plate 14 is forced to rotate in the opposite direction under the action of the torsion spring 29, and the control rod 16 is driven to move towards the initial position.

Embodiment 5, on the basis of embodiment 3, as shown in fig. 7, an extruding rod 25 is integrally disposed at one end of a driving rod 30 disposed outside a lower mold 2, a driven rod 26 engaged with the extruding rod 25 is integrally disposed at a lower end surface of an upper control rod 16, when an upper end surface of an abutting rod 17 is just flush with an upper end surface of the control rod 16 under the action of an arc plate 19 and a protruding plate 20 engaged with each other, a sidewall of the extruding rod 25 just abuts against a sidewall of the driven rod 26 (as shown in fig. 9), and then the driving rod 30 is continuously driven to move outwards along with the continuous increase of the temperature in the mold (at this time, the lower control rod 16 cannot continuously move outwards, and a blocking rod 31 abuts against the inner wall of the lower mold 2), the upper control rod 16 is driven to move by the abutting together of the extruding rod 25 and the driven rod 26, so that the valve plate 13 disposed above rotates from a horizontal position to a vertical position, therefore, a double channel is opened for cooling and heat dissipation, and in the process that the driving rod 30 continues to move outwards, the expansion spring 33 connected between the sliding block 32 and the control rod 16 is continuously stretched through the meshing between the gear 21 and the gear system 22 (at the moment, the lower control rod 16 is in the current position and cannot move due to the tension of the expansion spring 33 on the lower control rod 16);

if the dual channels are opened for cooling and heat dissipation for a period of time, the temperature in the mold begins to decrease, and the electromagnetic force of the electromagnet 24 is insufficient to overcome the force of the torsion spring 29 on the driving plate 14, the control rod 16 located above first starts to force the driving rod 30 corresponding thereto to slowly move in the opposite direction under the action of the torsion spring 29, and during the movement of the upper control rod 16 to the initial position, the extension spring 33 connected between the sliding block 32 and the lower control rod 16 is gradually reduced in tension (the tension of the extension spring 33 on the lower control rod 16 is also gradually reduced), so that when the upper valve plate 13 rotates to the initial horizontal position, the pressing rod 25 and the driven rod 26 just separate from each other and no longer have any force, and at the same time, the driving rod 30 just makes the gear 21 engaged with the rack 22 move to the initial position (i.e. the extension spring 33 connected between the sliding block 32 and the control rod 16 is in the initial state and no longer generates tension on the control rod 16) ) At this time, one end of the driving head moves to a position corresponding to the side wall of the abutting rod 17 (except that the upper end surface of the abutting rod 17 is kept flush with the upper end surface of the control rod 16 under the action of the convex plate 20 and the arc-shaped plate 19);

it is to be noted here that: when the extension spring 33 is provided, when the valve plate 13 rotates to 90 °, the acting force of the torsion spring 29 on the driving plate 14 cannot drive the lower control rod 16 to move into the mold (i.e. the elastic force of the extension spring 33 connected between the slider 32 and the lower control rod 16 cannot be overcome, the acting force of the torsion spring 29 cannot compress the extension spring 33, the gear 21 and the control rod 16 are in hard connection, and then the driving rod 30 and the lower control rod 16 move synchronously), at this time, the lower control rod 16 is in the current position by the attraction of the electromagnet 24 on the iron sheet 23 on the driving rod 30, the electromagnetic force is further reduced along with the continuous reduction of temperature, the control rod 16 is driven to move into the mold under the action of the torsion spring 29, and the driving rod 30 is driven to move into the mold synchronously through the meshing relationship between the gear 21 and the dentition 22, when the convex plate 20 is separated from the arc plate 19, the abutting rod 17 moves up to the initial position under the action of the grounding spring and abuts against one end of the head of the driving rod 30 again, and when the lower valve plate 13 rotates to the initial horizontal position, the heat dissipation of the die is stopped and no water flows in the heat dissipation pipe.

Embodiment 6, on the basis of embodiment 5, two control rods 16 are provided with limiting rods 27 at intervals, as shown in fig. 7, the limiting rods 27 are provided at the outer portions of the two control rods 16, which are disposed on the lower mold 2, so that when the control rods 16 move towards the lower mold 2, the limiting rods 27 abut against the outer wall of the lower mold 2 to achieve a better limiting effect when the control rods 16 move to the initial position.

The above description is only for the purpose of illustration, and it should be understood that the present invention is not limited to the above embodiments, and various modifications conforming to the spirit of the present invention are within the scope of the present invention.
