Description

Technical Field

[0001] The invention relates to the technical field of mold furnaces, in particular to an infrared mold furnace and a heating method for a mold used for processing aluminum profiles. Background Art

[0002] The structure of the infrared mold furnace includes a furnace body, an insulation layer, a heating coil, a fan, an electric heating tube and an adsorption plate. The infrared radiation heat generated by the coil induction heating or the electric heating wire is transferred to the mold through the infrared radiation plate. The mold absorbs electromagnetic energy and converts it into heat energy, thereby achieving rapid heating. Aluminum profiles are generally produced by mold stamping processing. In order to ensure the stamping effect, the stamping mold of the aluminum profile usually needs to be preheated before use. The preheated stamping mold will soften the aluminum profile to be processed by heat, thereby facilitating the forming of the aluminum profile.

[0003] Chinese patent CN219797904U discloses an infrared mold heating furnace that is convenient for filling molds. By setting up multiple drawer-type designs, the number of molds that can be used can be increased.

[0004] However, in the prior art, when the mold is taken out of the mold furnace after heating, it is necessary to take down the mold placed on the material cart and then put in the mold to be heated. Since the temperature of the mold surface is too high, it is necessary to use a special high-temperature resistant clamp or heat-insulating gloves to take down the mold. It takes a lot of time to take down the mold, which causes the mold furnace door to be opened for a long time. The long time the furnace door is opened will lead to a large heat loss. The above device lacks a design for quickly changing the mold. Therefore, an infrared mold furnace is proposed, which can quickly take out the heated mold and put in the mold to be heated.

[0027] (III) Beneficial effects

[0028] Compared with the prior art, the present invention provides an infrared mold furnace and a heating method for a mold for aluminum profile processing, which has the following beneficial effects:

[0029] 1. The infrared mold furnace is provided with a fixed track on the support frame, which cooperates with the sliding track arranged on one side of the furnace body. When the mold for aluminum profile processing is heated inside the mold furnace, the mold frame can be directly moved to the sliding track, and the mold frame on which the mold to be heated is placed in advance on the sliding track is pushed to the fixed track, thereby increasing the speed of replacing the mold for heating, thereby reducing the time of opening the furnace door and achieving the purpose of reducing heat loss.

[0030] 2.

At the same time, due to the arrangement of the horizontal sliding rod, the connecting block, the fixed sliding sleeve, the rotating plate and the telescopic spring, when the furnace door is away from the extrusion control rod, the telescopic spring is shortened, and the horizontal sliding rod pushes the rotating plate to rotate, so that the sliding plug plate moves upward and is inserted into the slot to fix the mold frame.

[0051] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0052] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 The present invention provides an infrared mold furnace, comprising a furnace body 1, an opening and closing track 2, a support frame 11, a furnace door 12 and a mold frame 6, wherein the opening and closing track 2 is arranged at the front side of the furnace body 1, one end of the support frame 11 enters and exits the furnace body 1, the furnace door 12 is fixedly installed at the other end of the support frame 11, and the lower end of the furnace door 12 is installed on the opening and closing track 2, a fixed track 3 is installed on the support frame 11, a sliding track 4 is arranged on the side of the opening and closing track 2, and the mold frame 6 moves between the sliding track 4 and the fixed track 3;

[0053] A rail-resting mechanism 5 is provided between the opening and closing rail 2 and the sliding rail 4. The rail-resting mechanism 5 includes a vertical slider 51 and a rotating plate 52. The vertical slider 51 slides in the vertical direction. Both ends of the rotating plate 52 are rotatably connected to the sliding rail 4 and the vertical slider 51. When the vertical slider 51 slides downward, the rotating plate 52 pulls the sliding rail 4 to abut against one end of the fixed rail 3. When the vertical slider 51 slides upward, the rotating plate 52 pushes the sliding rail 4 away from the fixed rail 3.

[0054] The support frame 11 is also provided with a self-locking mechanism 7, which includes a sliding plate 74, which slides vertically on the support frame 11, and the upper end of the sliding plate 74 is plugged into the bottom of the mold frame 6;

[0055] A control mechanism 8 is rotatably provided at one end of the opening and closing track 2 away from the furnace body 1, and the control mechanism 8 includes an extrusion control rod 88, which is rotatably installed on the opening and closing track 2. When the furnace door 12 is away from the furnace body 1, the extrusion control rod 88 is pushed to rotate, so that the extrusion control rod 88 pulls the vertical slider 51 and the sliding plug plate 74 to slide downward. When the furnace door 12 is away from the extrusion control rod 88, the extrusion control rod 88 rotates and resets, pushing the vertical slider 51 and the sliding plug plate 74 to slide upward.

[0056] As can be seen from the above, the infrared mold furnace, by arranging a fixed rail 3 on the support frame 11, cooperates with the sliding rail 4 arranged on one side of the furnace body 1. When the aluminum profile processing mold is heated inside the mold furnace, the mold frame 6 can be directly moved to the sliding rail 4, and the mold frame 6 on the sliding rail 4 on the other side where the mold to be heated is placed in advance is pushed onto the fixed rail 3, thereby increasing the speed of replacing the mold for heating, thereby reducing the time for opening the furnace door 12, and achieving the purpose of reducing heat loss. In addition, by arranging a rail mechanism 5 to drive the sliding rail 4 to move, the mold frame 6 can be directly moved to the sliding rail 4. The extrusion control rod 88 is controlled by the opening and closing of the furnace door 12. Only when the furnace door 12 moves away from the furnace body 1 and moves to the other side of the sliding track 4, the sliding track 4 will move close to the fixed track 3 to avoid the sliding track 4 from hindering the movement of the furnace door 12. By setting the self-locking mechanism 7, only when the distance between the furnace door 12 and the furnace body 1 is within a certain range, the sliding plug plate 74 will move upward to fix the mold frame 6 placed on the fixed track 3, so that when the sliding track 4 is connected to the fixed track 3, the self-locking mechanism 7 will not hinder the movement of the mold frame 6 placed on the fixed track 3.

[0057] When using the infrared mold furnace, the aluminum profile processing mold to be heated is placed in the mold frame 6 on the sliding track 4 on one side; the furnace door 12 is controlled to open and move away from the furnace body 1, driving the mold frame 6 placed on the fixed track 3 to completely escape from the interior of the furnace body 1, and after the furnace door 12 is fully opened, the mold frame 6 on the fixed track 3 is pushed to move to the sliding track 4 on the other side; the mold frame 6 placed on the sliding track 4 on one side is pushed onto the fixed track 3; the furnace door 12 is closed, and the infrared heating structure inside the furnace body 1 is started to heat the aluminum profile processing mold in the mold frame 6 on the fixed track 3.

[0058] The infrared heating structure mainly includes an infrared heating tube, a reflective cover, a temperature sensor and a power regulating device, which are used for heating during the operation of the infrared mold furnace. Embodiment 2

[0059] like Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, the difference between this embodiment and the above-mentioned embodiment is that the control mechanism 8 also includes a rotating seat 81, an incomplete gear 82, a sliding rack 83, a return spring 84, a pull plate 85, a baffle 86 and a guide rod 87. The rotating seat 81 is fixedly mounted on the opening and closing track 2, the extrusion control rod 88 is rotatably mounted on the rotating seat 81, the incomplete gear 82 is fixedly mounted on the outer side of the extrusion control rod 88, and the center of the incomplete gear 82 is colinear with the rotation axis of the extrusion control rod 88, the sliding rack 83 is meshed with the incomplete gear 82, the pull plate 85 and the baffle 86 are respectively fixedly mounted on the two ends of the sliding rack 83, the two ends of the guide rod 87 are respectively fixedly connected to the pull plate 85 and the baffle 86, and the guide rod 87 passes through the rotating seat 81 and is slidably connected to the rotating seat 81, the return spring 84 is sleeved on the guide rod 87, and the two ends of the return spring 84 are respectively fixedly connected to the rotating seat 81 and the pull plate 85.

[0060] As can be seen from the above, since the two ends of the guide rod 87 are fixedly connected to the pull plate 85 and the baffle 86 respectively, and the guide rod 87 passes through the rotating seat 81 and is slidably connected to the rotating seat 81, when the return spring 84 is compressed, it has a thrust to push the sliding rack 83 fixedly connected to the pull plate 85 and the baffle 86 to move. Since the sliding rack 83 is meshed with the incomplete gear 82, and the incomplete gear 82 is fixedly installed on the outer side of the extrusion control rod 88, when the extrusion control rod 88 rotates, it can drive the incomplete gear 82 to rotate, and when the incomplete gear 82 rotates, it can also drive the extrusion control rod 88 to rotate; when the furnace door 12 pushes the extrusion control rod 88 to rotate, under the huge thrust of the furnace door 12, the return spring 84 is extended, and when the furnace door 12 is away from the extrusion control rod 88, the return spring 84 automatically shortens, so that the incomplete gear 82 drives the extrusion control rod 88 to reverse and reset.

[0061] The shape of the extrusion control rod 88 is L-shaped, and the two ends of the extrusion control rod 88 are respectively set as a pressure deflection rod 881 and a driven pressure rod 882 with its rotation axis as an interval. A push block 16 is fixedly installed at the lower end of the furnace door 12, and the lower end of the push block 16 is close to the rotation axis of the extrusion control rod 88. The length of the driven pressure rod 882 is greater than the distance from the rotation axis of the extrusion control rod 88 to the lower end of the furnace door 12.

[0062] As can be seen from the above, since the push block 16 is fixedly installed at the lower end of the furnace door 12, and the lower end of the push block 16 is close to the rotation axis of the extrusion control rod 88, when the furnace door 12 is close to the extrusion control rod 88, it can push the compressed deflection rod 881 to rotate, so that the compressed deflection rod 881 rotates from a vertical state to a nearly horizontal state. When the compressed deflection rod 881 rotates from a nearly horizontal state, the driven pressure rod 882 also rotates from a horizontal state to a nearly vertical state. At this time, since the length of the driven pressure rod 882 is greater than the distance from the rotation axis of the extrusion control rod 88 to the lower end of the furnace door 12, the driven pressure rod 882 is in close contact with the inner wall of one side of the furnace door 12. Embodiment 3

[0063] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the difference between this embodiment and the above embodiment is that the rail-resting mechanism 5 also includes a guide rail 53 and a support rail 54, the guide rail 53 and the support rail 54 are both fixedly installed on the side of the opening and closing rail 2, and there is a gap between the guide rail 53 and the support rail 54 and the furnace door 12, the vertical slider 51 is slidably installed on the guide rail 53, and the lower end of the sliding rail 4 is equipped with a rolling wheel 41, and the rolling wheel 41 is rollingly connected to the upper surface of the support rail 54.

[0064] As can be seen from the above, when the vertical slide block 51 slides up and down on the guide rail 53 , the inclination angle of the rotating plate 52 changes, driving the sliding rail 4 to slide on the supporting rail 54 .

[0065] An extension rod 55 is fixedly installed on one end of the pressure-bearing deflection rod 881 away from the driven pressure rod 882 , and a horizontal sliding hole 56 is opened on one end of the vertical slider 51 away from the furnace body 1 , and the extension rod 55 is slidably installed inside the horizontal sliding hole 56 .

[0066] As can be seen from the above, by setting the extension rod 55 and the horizontal sliding hole 56, when the push block 16 squeezes the compressed deflection rod 881 to rotate, the height of the compressed deflection rod 881 gradually decreases, and the extension rod 55 slides in the horizontal sliding hole 56 while pulling the vertical slider 51 downward, so that the sliding track 4 is close to the fixed track 3; when the push block 16 moves in the opposite direction, the compressed deflection rod 881 reverses and resets, and the extension rod 55 slides in the horizontal sliding hole 56 while pulling the vertical slider 51 upward, so that the sliding track 4 is away from the fixed track 3.

[0067] A booster spring 57 is also provided on the guide rail 53 . The upper end of the booster spring 57 is fixedly connected to the lower surface of the vertical slider 51 , and the lower end of the booster spring 57 is fixedly connected to the guide rail 53 .

[0068] It can be seen from the above that since the compressed deflection rod 881 is driven by the thrust of the return spring 84 when it reverses and resets, during the process of the compressed deflection rod 881 reversing and resetting, the thrust of the return spring 84 on the compressed deflection rod 881 gradually decreases, and the force driving the sliding rail 4 to move also gradually decreases. When the force driving the sliding rail 4 to move decreases to a certain level, the debris and impurities sticking to the surface of the support rail 54 may hinder the movement of the sliding rail 4, causing the movement of the sliding rail 4 to be hindered. By setting the assist spring 57, the vertical slider 51 can slide upward stably to ensure the movement of the sliding rail 4.

[0069] The self-locking mechanism 7 also includes a horizontal slide bar 71, a connecting block 72, a fixed slide sleeve 73 and a rotating plate 75. The horizontal slide bar 71 is slidably installed at the bottom of the support frame 11, the connecting block 72 is fixedly installed on the surface of the horizontal slide bar 71, the fixed slide sleeve 73 is fixedly installed on the inner wall of the support frame 11, the sliding plug plate 74 is slidably installed inside the fixed slide sleeve 73, and the two ends of the rotating plate 75 are rotatably connected to the connecting block 72 and the sliding plug plate 74 respectively. A slot 61 is fixedly provided on the lower surface of the mold frame 6, and the slot 61 is cooperated with the sliding plug plate 74. A stop block 78 is also fixedly installed on one side of the opening and closing track 2, and the stop block 78 abuts against the lower surface of the compressed deflection rod 881 in the horizontal state.

[0070] As can be seen from the above, when the driven pressure rod 882 is in a state close to vertical, it is closely fitted with the inner wall of one side of the furnace door 12, and the furnace door 12 continues to move in the direction away from the furnace body 1, which will cause the horizontal slide bar 71 to contact the side of the driven pressure rod 882. Since the stop block 78 abuts against the lower surface of the compressed deflection rod 881 in the horizontal state, when the horizontal slide bar 71 pushes the driven pressure rod 882 to make the driven pressure rod 882 in a vertical state, the driven pressure rod 882 cannot continue to rotate, so the horizontal slide bar 71 will slide inside the support frame 11, so that the connecting block 72 is away from the adjacent fixed sleeve 73, thereby increasing the inclination angle of the rotating plate 75, and the sliding insert plate 74 slides downward and separates from the slot 61. Therefore, when the furnace door 12 reaches the farthest position from the furnace body 1, the mold frame 6 can move freely.

[0071] A connecting piece 17 is fixedly installed at the bottom of the support frame 11, one end of the horizontal slide bar 71 is slidably connected to the connecting piece 17, and a limit block 76 is fixedly installed at one end of the horizontal slide bar 71, and a telescopic spring 77 is fixedly installed between the limit block 76 and the connecting piece 17.

[0072] Due to the setting of the telescopic spring 77 and the limit block 76, before the horizontal slide bar 71 contacts the driven pressure rod 882, the horizontal slide bar 71 is fixed relative to the support frame 11. When the horizontal slide bar 71 squeezes the driven pressure rod 882, the telescopic spring 77 begins to extend and pulls the connecting block 72 away from the fixed slide sleeve 73; similarly, when the furnace door 12 drives the horizontal slide bar 71 to gradually move away from the driven pressure rod 882, the telescopic spring 77 begins to shorten, causing the sliding plug plate 74 to start rising and insert into the slot 61. In this embodiment, the upper end of the sliding plug plate 74 and the lower end of the slot 61 can be provided with an inclined structure that is easy to plug in and increases the contact area of ​​the structure, so that the difficulty of plugging and limiting between the sliding plug plate 74 and the slot 61 is reduced. Embodiment 4

[0073] like Figure 1 , Figure 3 and Fig. 9As shown, the difference between this embodiment and the above embodiment lies in that a furnace track 15 is fixedly installed on the inner bottom of the furnace body 1, a bracket moving wheel 13 is installed on the lower surface of the support frame 11 away from the furnace door 12, and the bracket moving wheel 13 is rollingly installed on the furnace track 15, a support wheel 14 is installed on the bottom of the furnace door 12, and the support wheel 14 is rollingly installed on the opening and closing track 2, and a frame moving wheel 62 is fixedly installed on the lower surface of the mold frame 6, and the frame moving wheel 62 is rollingly adapted to the fixed track 3 and the sliding track 4.

[0074] As can be seen from the above, by providing the support moving wheels 13 and the support wheels 14, the movement of the support frame 11 and the furnace door 12 is made more stable, and by providing the frame moving wheels 62, the mold frame 6 is facilitated to move on the fixed track 3 and the sliding track 4.

[0075] A cylinder 9 is fixedly mounted on the bottom of the furnace body 1 , and a driving end of the cylinder 9 is fixedly connected to the lower surface of the furnace door 12 .

[0076] As can be seen from the above, by setting up the cylinder 9, it is used to control the opening and closing of the furnace door 12 and the compression seal between the furnace door 12 and the furnace body 1. The action of the cylinder 9 to push the furnace door 12 to move is sufficient to resist the elastic force of the return spring 84 and the booster spring 57 while driving the vertical slider 51 to move downward. Embodiment 5
