Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, specifically to a mold heating furnace for aluminum profile processing. Background Technology

[0002] Generally, molds are used in the extrusion process of aluminum profiles. The temperature is high during the extrusion process of aluminum profiles. In order to avoid a large temperature difference between the aluminum profile and the mold, which would affect the quality, the mold needs to be preheated in a heating furnace before processing. However, after heating, the surface temperature of the mold is higher than the internal temperature. Direct use will lead to uneven temperature, which will affect the quality of product forming during the aluminum profile processing. Therefore, it is necessary to keep it at the set temperature before use.

[0003] Because the mold holes and end faces in the middle of the mold have a larger contact area with the external environment, they cool down faster than other parts of the mold. This results in different cooling rates on the mold surface, causing uneven shrinkage in different parts of the mold, leading to overall or localized deformation and affecting its efficiency in processing aluminum profiles. At the same time, after the mold is kept in the insulation cover to the set temperature, the temperature on the mold surface is still high, making it inconvenient to transfer it out of the insulation cover and affecting the efficiency of mold installation. Summary of the Invention

[0004] The technical problem solved by this solution is:

[0005] (1) How to solve the problem that the mold hole and end face in the middle of the mold cool down faster than other parts, causing uneven shrinkage in different parts of the mold, resulting in overall or local deformation, and affecting its processing efficiency for aluminum profiles;

[0006] (2) How to solve the problem that after the mold is kept in the heat insulation cover to the set temperature, the temperature of the mold surface is still high, making it inconvenient to transfer it out of the heat insulation cover and affecting the efficiency of mold installation.

[0007] The objective of this invention can be achieved through the following technical solution: a mold heating furnace for aluminum profile processing, comprising a furnace body and a heat insulation cover disposed on one side thereof, wherein a support plate for placing molds is disposed inside the heat insulation cover, a first opening is provided in the middle of the support plate, and a heat insulation mechanism for heating the molds is disposed above the support plate, and a material discharge mechanism for quickly unloading molds is also disposed inside the heat insulation cover.

[0008] The heat preservation mechanism includes a horizontally arranged electric heating plate, a second opening in the middle of the electric heating plate, the position of the second opening corresponding to the position of the first opening, and a fixing sleeve fixedly installed on the inner wall of the heat preservation cover above the electric heating plate.

[0009] A further technical improvement of the present invention is that: an electric push rod is fixedly inserted into the top of the heat preservation cover, the electric push rod is arranged longitudinally, and a push plate is fixedly installed at the extended end of the electric push rod. An electric heating rod is fixedly installed at the bottom of the push plate, and the diameter of the push plate is larger than the diameter of the second opening; this facilitates pushing the electric heating plate downward by the push plate.

[0010] A further technical improvement of the present invention is that: the push plate is located inside the fixed sleeve, and the diameter of the push plate is smaller than the inner diameter of the fixed sleeve, and the bottom end of the electric heating rod is located inside the second opening; since the diameter of the push plate is smaller than the inner diameter of the fixed sleeve, contact between the push plate and the fixed sleeve is avoided.

[0011] A further technical improvement of the present invention is that: a blower is fixedly installed on the top of the outer wall of the heat insulation cover, the output end of the blower is connected to a blowing pipe, the output end of the blowing pipe passes through the heat insulation cover and is connected to the middle of the fixed sleeve.

[0012] A further technical improvement of the present invention is that: lifting rods are fixedly installed at the top of both ends of the electric heating plate, the top of the lifting rods movably penetrates the heat insulation cover, and a baffle is fixedly installed thereon; a first thrust spring is sleeved on the outer wall of the lifting rod between the baffle and the heat insulation cover; by turning on the blower, electric heating rod, and electric heating plate, the blown airflow enters the fixed sleeve. Due to the thrust of the two first thrust springs, the two lifting rods pull the electric heating plate upward together. At this time, the electric heating plate contacts the bottom of the fixed sleeve, preventing airflow leakage inside the fixed sleeve. After the airflow is heated by the electric heating rod and electric heating plate, it is blown out from the second opening, which facilitates heating the air inside the heat insulation cover and prevents the mold from directly contacting the cold air outside after being taken out of the heating furnace body. At this time, the moving plate moves most of the side area of ​​the heat insulation cover close to the heating furnace body. The insulation layer acts as a shield to prevent excessive heat loss. After heating the mold, the output of the servo motor is reversed, causing the support plate to move and reset. Heat blown out from the furnace body's inlet and outlet enters the insulation layer for recycling, thus keeping the mold warm. The extension of the electric push rod is then controlled to extend from its shortest length, causing the push plate to move the electric heating plate downwards. The blower is then turned off. When the extension of the electric push rod reaches its maximum length, there is a 1 cm distance between the electric heating plate and the top of the mold. At this point, the bottom of the electric heating rod penetrates the mold hole and is located in the first opening. The electric heating rod and the electric heating plate heat and insulate the mold hole and top surface respectively, preventing uneven cooling and shrinkage of different parts of the mold, which could cause overall or local deformation and affect the efficiency of aluminum profile processing.

[0013] A further technical improvement of the present invention is that: the discharge mechanism includes a discharge plate, the discharge plate is located on the front of the support plate, and a sliding plate is slidably disposed on the top of the discharge plate via a guide rail. A sealing plate is fixedly installed on the top of the sliding plate, and the top surface height of the sliding plate is the same as the top surface height of the support plate. The sliding plate and the support plate are always in a separated state, which facilitates pushing the mold to the top of the sliding plate.

[0014] A further technical improvement of the present invention is that: a cylinder is fixedly installed on the back of the heat insulation cover, and a feeding block is fixedly connected to the extended end of the cylinder. The bottom surface of the feeding block is higher than the top surface of the support plate, and a groove for positioning the mold is opened on the side of the feeding block facing the sealing plate. Since the bottom surface of the feeding block is higher than the top surface of the support plate, the feeding block is prevented from contacting the support plate. When the extended end of the cylinder is in the shortest state, the feeding block and the support plate are separated, thus avoiding affecting the movement of the support plate.

[0015] A further technical improvement of the present invention is that: the front of the heat insulation cover is provided with a discharge port, the size of the discharge port corresponds to the size of the sealing plate, and the bottom center of the bottom surface of the feeding plate is fixedly connected to the bottom of the inner wall of the discharge port.

[0016] A further technical improvement of the present invention is as follows: a fixing plate is fixedly installed on the top surface of the feeding plate, a connecting rod is movably inserted into the middle of the fixing plate, one end of the connecting rod is fixedly connected to the sealing plate, and a second thrust spring is elastically arranged between the fixing plate and the sealing plate; after the mold is kept warm to the threshold, the extended end of the electric push rod is controlled to retract and reset, and then the extended end of the cylinder is controlled to extend from the shortest to the longest, so that the feeding block moves, and the mold is moved to the top of the sliding plate through the groove. At the same time, the feeding block provides a thrust to the sealing plate, so that the sliding plate, under the guidance of the guide rail, drives the sealing plate to separate from the discharge port, which facilitates the quick transfer of the mold located at the top of the sliding plate out of the heat preservation cover and avoids affecting the efficiency of mold installation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In use, this invention involves activating the blower, electric heating rod, and electric heating plate, allowing the blown airflow to enter the fixed sleeve. Due to the thrust of the two first thrust springs, the two lifting rods pull the electric heating plate upwards together. At this point, the electric heating plate contacts the bottom of the fixed sleeve, preventing airflow leakage. After being heated by the electric heating rod and electric heating plate, the airflow exits through the second opening, facilitating the heating of the air inside the insulation cover and preventing the mold from directly contacting the cold outside air after being removed from the heating furnace. Because the moving plate at this time blocks most of the side of the insulation cover near the heating furnace body, it prevents significant heat loss from the insulation cover. After heating the mold, the servo motor is controlled... The output end rotates in the opposite direction, causing the support plate to move and reset. The heat blown out from the inlet and outlet of the heating furnace body will enter the insulation cover, where the heat will be recovered and reused to keep the mold warm. Then, the extension end of the electric push rod is controlled to extend from its shortest length, causing the push plate to push the electric heating plate downwards and the blower to be turned off in time. When the extension end of the electric push rod is extended to its longest length, there is a 1 cm distance between the electric heating plate and the top of the mold. At this time, the bottom end of the electric heating rod penetrates the mold hole and is located in the first opening. The electric heating rod and the electric heating plate heat and keep the mold hole and the top surface of the mold warm respectively, avoiding uneven cooling and shrinkage of different parts of the mold, which may cause overall or local deformation and affect the efficiency of aluminum profile processing.

[0019] In use, after the mold has been kept at a certain temperature threshold, the extended end of the electric push rod is controlled to retract and reset. Then, the extended end of the cylinder is controlled to extend from its shortest length to its longest length, causing the material unloading block to move. This moves the mold to the top of the sliding plate via the groove. At the same time, the material unloading block provides a pushing force to the sealing plate, causing the sliding plate to separate from the outlet under the guidance of the guide rail. This facilitates the quick transfer of the mold located at the top of the sliding plate out of the insulation cover, avoiding any impact on the efficiency of mold installation.

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-6 As shown, a mold heating furnace for aluminum profile processing includes a furnace body 9 and a heat insulation cover 2 disposed on one side thereon. The heat insulation cover 2 is provided with a support plate 13 for placing molds. A first opening 14 is provided in the middle of the support plate 13, and a heat insulation mechanism 1 for heating the mold is provided above the support plate 13. The heat insulation cover 2 is also provided with a discharge mechanism 7 for quickly unloading molds.

[0030] Please see Figures 2-4 As shown, the above-mentioned heat preservation mechanism 1 includes a horizontally arranged electric heating plate 110. A second opening 105 is provided in the middle of the electric heating plate 110. The position of the second opening 105 corresponds to the position of the first opening 14. A fixing sleeve 107 is fixedly installed on the inner wall of the heat preservation cover 2 above the electric heating plate 110.

[0031] Please see Figure 3 As shown, an electric push rod 101 is fixedly inserted into the top of the above-mentioned heat insulation cover 2. The electric push rod 101 is arranged longitudinally, and a push plate 104 is fixedly installed at the extended end of the electric push rod 101. An electric heating rod 106 is fixedly installed at the bottom of the push plate 104, and the diameter of the push plate 104 is larger than the diameter of the second opening 105; so as to facilitate the push plate 104 to push the electric heating plate 110 downward.

[0032] Please see Figure 3 and Figure 4 As shown, the push plate 104 is located inside the fixed sleeve 107, and the diameter of the push plate 104 is smaller than the inner diameter of the fixed sleeve 107. The bottom end of the electric heating rod 106 is located inside the second opening 105. Since the diameter of the push plate 104 is smaller than the inner diameter of the fixed sleeve 107, the push plate 104 is prevented from contacting the fixed sleeve 107.

[0033] Please see Figure 2 and Figure 3 As shown, a blower 3 is fixedly installed on the top of the outer wall of the above-mentioned heat insulation cover 2. The output end of the blower 3 is connected to a blower pipe 103. The output end of the blower pipe 103 passes through the heat insulation cover 2 and is connected to the middle of the fixed sleeve 107.

[0034] Please see Figure 4 As shown, lifting rods 102 are fixedly installed at both ends of the electric heating plate 110. The top of the lifting rod 102 moves through the heat insulation cover 2 and is fixedly installed with a baffle 109. A first thrust spring 108 is sleeved on the outer wall of the lifting rod 102 between the baffle 109 and the heat insulation cover 2. By turning on the blower 3, the electric heating rod 106 and the electric heating plate 110, the blown airflow enters the fixed sleeve 107. Due to the thrust of the two first thrust springs 108, the two lifting rods 102 pull the electric heating plate 110 upward together. At this time, the electric heating plate 110 contacts the bottom end of the fixed sleeve 107 to prevent the airflow in the fixed sleeve 107 from leaking. After the airflow is heated by the electric heating rod 106 and the electric heating plate 110, it is blown out from the second opening 105 to heat the air in the heat insulation cover 2 and prevent the mold from directly contacting the cold air outside after being taken out of the heating furnace body 9. At this time, the moving plate 10 moves the heat insulation cover 2 closer to the heating furnace body. Most of the side area of ​​the furnace 9 is shielded to prevent a large amount of heat loss from the heat insulation cover 2. After the mold is heated, the output end of the servo motor 4 is controlled to rotate in the opposite direction, so that the support plate 13 moves and resets. The heat blown out from the inlet and outlet of the furnace body 9 will enter the heat insulation cover 2 and be recycled to keep the mold warm. Then, the extension end of the electric push rod 101 is controlled to extend from its shortest length, so that the push plate 104 pushes the electric heating plate 110 downward and the blower 3 is turned off in time. When the extension end of the electric push rod 101 is extended to its longest length, there is a 1 cm distance between the electric heating plate 110 and the top of the mold. At this time, the bottom end of the electric heating rod 106 penetrates the mold hole and is located in the first opening 14. The electric heating rod 106 and the electric heating plate 110 heat and keep the mold hole and the top surface of the mold warm, respectively, to avoid uneven cooling and shrinkage of different parts of the mold, which may cause overall or local deformation and affect the efficiency of aluminum profile processing.

[0035] Please see Figure 1 and Figure 5 As shown, the above-mentioned discharge mechanism 7 includes a discharge plate 704, which is located on the front of the support plate 13. A sliding plate 705 is slidably disposed on the top of the discharge plate 704 via a guide rail. A sealing plate 703 is fixedly installed on the top of the sliding plate 705. The top surface height of the sliding plate 705 is the same as the top surface height of the support plate 13. The sliding plate 705 and the support plate 13 are always separated, which facilitates pushing the mold to the top of the sliding plate 705.

[0036] Please see Figure 5 and Figure 6 As shown, a cylinder 701 is fixedly installed on the back of the aforementioned heat insulation cover 2. A feeding block 706 is fixedly connected to the extended end of the cylinder 701. The bottom surface of the feeding block 706 is higher than the top surface of the support plate 13, and a groove 702 for positioning the mold is opened on the side of the feeding block 706 facing the sealing plate 703. Since the bottom surface of the feeding block 706 is higher than the top surface of the support plate 13, the feeding block 706 is prevented from contacting the support plate 13. When the extended end of the cylinder 701 is in the shortest state, the feeding block 706 and the support plate 13 are separated, so as to avoid affecting the movement of the support plate 13.

[0037] Please see Figure 5 and Figure 6 As shown, the heat insulation cover 2 has a discharge port 15 on its front side. The size of the discharge port 15 corresponds to the size of the sealing plate 703. The bottom center of the material feeding plate 704 is fixedly connected to the bottom of the inner wall of the discharge port 15.

[0038] Please see Figure 6 As shown, a fixing plate 707 is fixedly installed on the top surface of the above-mentioned feeding plate 704. A connecting rod 708 is movably inserted into the middle of the fixing plate 707. One end of the connecting rod 708 is fixedly connected to the sealing plate 703. A second thrust spring is elastically provided between the fixing plate 707 and the sealing plate 703. After the mold is kept warm to the threshold, the extended end of the electric push rod 101 is controlled to retract and reset. Then, the extended end of the cylinder 701 is controlled to extend from the shortest to the longest, so that the feeding block 706 moves. The mold is moved to the top of the sliding plate 705 through the groove 702. At the same time, the feeding block 706 provides a thrust to the sealing plate 703, so that the sliding plate 705, under the guidance of the guide rail, drives the sealing plate 703 to separate from the discharge port 15. This facilitates the quick transfer of the mold located on the top of the sliding plate 705 out of the heat preservation cover 2, avoiding affecting the efficiency of mold installation.

[0039] Please see Figure 1 As shown, a base 6 is fixedly installed at the bottom of the heat insulation cover 2. One end of the base 6 is fixedly connected to the heating furnace body 9, and a fixing seat 5 is fixedly installed at the top of the other end of the base 6. A servo motor 4 is fixedly installed on the top of the fixing seat 5.

[0040] Please see Figure 1 and Figure 2 As shown, the side of the aforementioned fixed base 5 is fixedly connected to two guide rods 11. One end of each guide rod 11 movably passes through the heat insulation cover 2 and is fixedly connected to the bottom of the heating furnace body 9. The inlet and outlet of the heating furnace body 9 are set towards the heat insulation cover 2, and a sealing gasket 8 is provided on its outer side.

[0041] Please see Figure 1 and Figure 2 As shown, the output end of the servo motor 4 is fixedly connected to a threaded screw 12. One end of the threaded screw 12 movably passes through the heat insulation cover 2 and is threadedly connected to a longitudinally arranged movable plate 10. The movable plate 10 is fixedly connected to the support plate 13. The middle parts of the two guide rods 11 both movably pass through the bottom of the movable plate 10.

[0042] Working principle: When using this invention, firstly, as... Figure 1 and Figure 2 As shown, by controlling the output of the servo motor 4 to rotate forward, the threaded screw 12 drives the moving plate 10 and the support plate 13 to move towards the heating furnace body 9. During this process, the movement of the moving plate 10 is guided by two guide rods 11. When the support plate 13 reaches between the heating furnace body 9 and the insulation cover 2, the servo motor 4 stops running. The mold is then placed on the top center of the support plate 13 by an external feeding device. Figure 1 and Figure 2 As shown, the output of the servo motor 4 continues to rotate in the forward direction, causing the support plate 13 to drive the mold into the heating furnace body 9. The heating furnace body 9 is then turned on to heat the mold. At this time, the moving plate 10 is in close contact with the sealing gasket 8, providing insulation for the heating furnace body 9 and preventing heat leakage from the furnace body 9. Figures 2-4 As shown, by turning on the blower 3, electric heating rod 106, and electric heating plate 110, the blown airflow enters the fixed sleeve 107. Due to the pushing force of the two first thrust springs 108, the two lifting rods 102 pull the electric heating plate 110 upward together. At this time, the electric heating plate 110 contacts the bottom end of the fixed sleeve 107, preventing airflow leakage within the fixed sleeve 107. After being heated by the electric heating rod 106 and electric heating plate 110, the airflow is blown out from the second opening 105, facilitating the heating of the air inside the insulation cover 2 and preventing the mold from directly contacting the cold air outside after being removed from the heating furnace body 9. Since the moving plate 10 blocks most of the side area of ​​the insulation cover 2 near the heating furnace body 9, it prevents a large amount of heat loss from the insulation cover 2. Figure 3 and Figure 4As shown, after the mold is heated, the output of the servo motor 4 is controlled to rotate in the opposite direction, causing the support plate 13 to move and reset. The heat blown out from the inlet and outlet of the heating furnace body 9 will enter the insulation cover 2 for recycling, thus keeping the mold warm. Then, the extension end of the electric push rod 101 is controlled to extend from its shortest length, causing the push plate 104 to push the electric heating plate 110 downward, and the blower 3 is turned off in time. When the extension end of the electric push rod 101 is extended to its longest length, there is a 1 cm distance between the electric heating plate 110 and the top of the mold. At this time, the bottom end of the electric heating rod 106 penetrates the mold hole and is located in the first opening 14. The electric heating rod 106 and the electric heating plate 110 heat and keep the mold hole and top surface warm respectively, avoiding uneven cooling and shrinkage of different parts of the mold, which may cause overall or local deformation and affect the efficiency of aluminum profile processing. Figure 5 and Figure 6 As shown, after the mold is kept at the threshold temperature, the extended end of the electric push rod 101 is retracted and reset, and the extended end of the cylinder 701 is extended from the shortest to the longest, causing the unloading block 706 to move. The mold is moved to the top of the sliding plate 705 through the groove 702. At the same time, the unloading block 706 provides a pushing force to the sealing plate 703, so that the sliding plate 705, guided by the guide rail, causes the sealing plate 703 to separate from the discharge port 15. This facilitates the quick transfer of the mold located on the top of the sliding plate 705 out of the heat preservation cover 2, avoiding affecting the efficiency of mold installation.
