The existing hair dryer barrel is generally molded by mold injection. The molding mold generally includes an upper mold and a lower mold. The two parts can be separated and combined. When separated, the workpiece is taken out. When combined, the blank is injected into the mold cavity for forming. However, the mold cavity space of the mold used to make this type of hair dryer is fixed, and the space size cannot be adjusted according to different models of products, resulting in a narrow application range.

[0016] As a further solution of the present invention: a cavity is opened inside the lower mold, a mounting seat is welded and fixed on the rotating disk, a mounting cavity is opened inside the mounting seat, a displacement mechanism is fixed inside the mounting cavity, and a support rod is fixed at one end of the displacement mechanism.

[0017] At the same time, a ring tube is movably installed on the side of the support rod, and the ring tube is movably installed inside the cavity. A friction seat is fixedly installed on the bottom of the rotating disk, and a mounting hole is opened inside the lower mold.

[0018] As a preferred embodiment of the present invention: a support column is movably installed inside the mounting hole, a support block is welded to one end of the support column, the support block is movably matched with the ring seat, a limiting block is fixed on the side of the support column, a groove is opened on the side of the support column, and the groove is movably contacted with one end of the limiting tube.

[0019] At the same time, a limiting groove is opened on the inner wall of the mounting hole, the limiting block is movably mounted inside the limiting groove, and a reset mechanism is fixedly mounted between the limiting block and the limiting groove.

[0022] Beneficial effects of the present invention:

[0023] 1. In the present invention, a positioning tube is installed inside the positioning hole, and the ring seat cooperates with the support block to push the support column to move downward. The downward movement of the support column causes the base and the lower mold to move upward as a whole and be suspended in the air. After the support column supports the base, the friction seat is separated from the ground. One end of the limiting tube is installed inside the groove of the support column through the limiting hole. The limiting tube simultaneously realizes the fixed support of the positioning tube and the support column. After the positioning tube is fixed, the shaking between the upper mold and the lower mold is effectively avoided, and the stability between the molds is effectively increased.

[0024] 2. In the present invention, air is blown inwardly by the exhaust fan inside the motor box, and the wind flows into the interior of the limit tube through the installation cavity, and then into the interior of the positioning tube through the air outlet hole on the limit tube. The wind flows into the interior of the pipe hole inside the upper mold through the positioning tube, and the high temperature on the mold is driven to be discharged outward through the cooperation of the pipe hole and the opening, thereby realizing rapid heat dissipation of the mold and being beneficial to the molding of the material.

[0025] 3. In the present invention, air is blown outwards through the pipe hole, and the wind blows the movable tube inside the opening to move outwards. After the movable tube moves, the opening leaks out, and the high temperature is easily discharged through the opening. The connecting holes cooperate to realize the wind flow in the lower mold to enter the upper mold again for cooling. During the early injection, the movable tube shrinks inside the opening for heat preservation.

[0026] 4. In the present invention, the displacement mechanism pushes the support rod to support the annular tubes of different diameters. The width of the gap between the annular tube and the cavity is adjusted by changing the diameter of the annular tube. The size of the cavity with different diameters is adjusted to complete the molding process of the wind tubes with different diameters and thicknesses. After the support column loses its supporting force, the friction seat contacts the ground, and the friction seat drives the rotating disk to rotate. When the rotating disk rotates, the support rod drives the annular tube to rotate. The rotation of the annular tube is beneficial to the later demoulding process.

[0027] 5. The present invention not only drives the fan blades to flow air through the dual-axis exhaust fan, but also drives the centrifugal mechanism to rotate through the spline shaft, thereby fully utilizing the power of the exhaust fan and maximizing the energy utilization. The gravity ball in the centrifugal mechanism generates a centrifugal outward expansion force when rotating, and drives the motor box to move outward through the connecting frame, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. The ingenious design of the opening and closing structure enables the limit tube to automatically open the ventilation channel when it is displaced, ensuring that the cooling air can smoothly enter the interior of the mold for efficient heat dissipation.

DETAILED DESCRIPTION

[0039] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] Embodiment 1:

[0042] A hair dryer air cylinder cavity size fine-tuning mold, such as Figure 1-Figure 8 , including a base 1,

[0043] A lower mold 2 is fixedly mounted on the base 1, and an upper mold 3 is movably mounted on the top of the lower mold 2;

[0044] A movable plate 4 is movably mounted on the top of the upper mold 3, a heating mechanism is fixedly mounted on the inner wall of the movable plate 4, the movable plate 4 is fixedly mounted on the upper mold 3 by fixing bolts 6, a feed pipe 5 is fixedly mounted on the upper mold 3, and a movable seat 7 is movably mounted on the side of the lower mold 2;

[0045] The movable seat 7 is mounted on the lower mold 2 via a limiting bolt 8 . A limiting seat 19 is movably mounted on the side of the lower mold 2 . The limiting seat 19 is movably mounted on the movable seat 7 .

[0046] When the device is in use, when feeding through the feed pipe 5, the heating mechanism on the inner wall of the movable plate 4 heats the position of the upper mold 3, and the heating mechanism is composed of an electric heating wire. The high temperature is generated by energizing the electric heating wire. The high temperature effectively prevents the material from cooling and solidifying when feeding through the feed pipe 5, thereby ensuring the fluidity of the material and facilitating the slow and even introduction of the material into the interior of the lower mold 2. Later, when the heating mechanism is damaged, the movable plate 4 can be disassembled separately by fixing the bolts 6. After the movable plate 4 is disassembled, the heating mechanism is replaced separately. The movable seat 7 is installed on the lower mold 2 by the limiting bolts 8. The movable seat 7 can be disassembled by the limiting bolts 8 later.

[0047] The device, through structural optimization, uses fixing bolts 6 and limiting bolts 8 to fix the movable seat 7 and the movable plate 4, so that the parts can be replaced separately later by fixing bolts 6 and limiting bolts 8, thereby preventing the waste of resources caused by the overall replacement of the device.

[0048] In order to solve the problem of heat dissipation and heat preservation; as shown in 2, the sides of the lower mold 2 and the upper mold 3 are each provided with an opening 9, and a movable tube 10 is movably installed inside the opening 9, and a through hole 11 is provided on the movable tube 10, and the lower mold 2 and the upper mold 3 are each provided with a connecting hole 13, and the connecting holes 13 are distributed in an upper and lower opposite manner.

[0049] The lower mold 2 is provided with a positioning hole 12 , a positioning tube 26 is movably installed inside the positioning hole 12 , one end of the positioning tube 26 is fixed on the upper mold 3 , a ring seat 27 is fixed on the positioning tube 26 , and a limiting hole 28 is provided on the positioning tube 26 .

[0050] The device controls the opening state of the through hole 11 by moving the movable tube 10 inside the opening 9, so that the movable tube 10 controls the opening or closing of the through hole 11 under the thrust of wind force, and controls the heat dissipation or heat preservation between the molds by opening or closing the through hole 11.

[0051] A limiting tube 25 is movably installed inside the limiting hole 28, and an air outlet 37 is opened on the limiting tube 25. The air outlet 37 is installed inside the positioning tube 26. One end of the limiting tube 25 is fixed on the limiting seat 19, and a protrusion 21 and a motor box 20 are fixedly installed on the limiting seat 19 respectively.

[0052] When the limit seat 19 needs to drive the limit tube 25 to move, the limit seat 19 is driven to move as a whole through the protrusion 21 as a support point. When the limit seat 19 moves, the limit tube 25 is pulled out from the lower mold 2. After the limit tube 25 is pulled out, it loses the limit on the upper mold 3, so that the upper mold 3 can be disassembled and separated.

[0053] The device uses the limiting tube 25 to simultaneously limit and fix the positioning tube 26 and the support column 35. The positioning tube 26 fixes the positioning tube 26 and facilitates the air flow to enter the interior of the positioning tube 26 through the air outlet 37, and guides the air flow to the interior of the upper mold 3 for cooling and heat dissipation.

[0054] In order to solve the demoulding and cavity size adjustment problems; Figure 4 As shown, a slide groove 17 is provided on the movable seat 7, a support mechanism 18 is fixedly installed inside the slide groove 17, a slider 38 is fixed at one end of the support mechanism 18, and one end of the slider 38 is fixed to the bottom of the limit seat 19, pipe holes 22 are provided inside the upper mold 3 and the lower mold 2, and the pipe holes 22 are respectively connected to the positioning hole 12, the connecting hole 13 and the opening 9, and a rotating disk 23 is rotatably installed on the base 1.

[0055] The lower mold 2 has a cavity 14 formed inside, a mounting seat 24 is welded and fixed on the rotating disk 23 , a mounting cavity 39 is formed inside the mounting seat 24 , a displacement mechanism 40 is fixedly installed inside the mounting cavity 39 , and a support rod 16 is fixed to one end of the displacement mechanism 40 .

[0056] A ring tube 15 is movably mounted on the side of the support rod 16 , and the ring tube 15 is movably mounted inside the cavity 14 . A friction seat 29 is fixedly mounted on the bottom of the rotating disk 23 , and a mounting hole 30 is opened inside the lower mold 2 .

[0057] During installation, the displacement mechanism 40 pushes the support rod 16 to move outward, and the support rod 16 forms an outward expansion force. The support rod 16 supports and fixes the inner wall of the annular tube 15 through the expansion force. Later, the support rod 16 moves inward and outward to fix and install the annular tubes 15 of different diameters.

[0058] In this device, the friction seat 29 is later in contact with the ground, so that the base 1 as a whole rotates with the friction seat 29 as a fulcrum. The friction seat 29 provides a limit fixation for the rotating disk 23, and the material between the cavity 14 and the annular tube 15 inside the lower mold 2 rotates. The rotation of the material realizes the separation and shedding of the inner wall of the cavity 14 and the outer wall of the annular tube 15, thereby facilitating the removal of the material after the later molding.

[0059] In order to achieve the problem of mold separation; Figure 6 As shown, a support column 35 is movably installed inside the mounting hole 30, and a support block is welded to one end of the support column 35, and the support block movably cooperates with the ring seat 27, and a limiting block 33 is fixed on the side of the support column 35, and a groove 36 is opened on the side of the support column 35, and the groove 36 is movably contacted with one end of the limiting tube 25, and a limiting groove 32 is opened on the inner wall of the mounting hole 30, and the limiting block 33 is movably installed inside the limiting groove 32, and a reset mechanism 34 is fixedly installed between the limiting block 33 and the limiting groove 32, a ventilation cavity is opened inside the limiting seat 19, and an exhaust fan 31 is fixedly installed inside the motor box 20.

[0060] This device separates the limiting tube 25 from the groove 36. After the support column 35 loses its support, it shrinks inside the mounting hole 30 under the pressure of the gravity of the lower mold 2 and the upper mold 3. As the support column 35 moves upward, the support column 35 pushes the positioning tube 26 to move upward. After the positioning tube 26 moves upward, the separation between the lower mold 2 and the upper mold 3 is opened, which facilitates the subsequent separation and opening of the upper mold 3 and the lower mold 2.

[0061] Embodiment 2:

[0062] Based on the first embodiment, Figure 6 , Figure 7 , Fig. 9 and Fig.10As shown, a centrifugal mechanism connected to the exhaust fan 31 is arranged on the outside of the movable seat 7, and the centrifugal mechanism includes an abutment seat 41, a spline sleeve 42, a rotating sleeve 43, a swing arm 44, a gravity ball 45 and a connecting rod 46. The exhaust fan 31 is composed of a dual-axis motor and fan blades. The right output shaft of the exhaust fan 31 is fixedly installed with a spline shaft 47 spline-connected to the spline sleeve 42, and a return spring 48 is installed between the spline sleeve 42 and the abutment seat 41. The swing arm 44 is hingedly installed on the outer surface of the abutment seat 41, and the gravity ball 45 is fixed to the other end of the swing arm 44. The connecting rod 46 is hingedly installed between the spline sleeve 42 and the swing arm 44. A guide rod 52 that runs through the inside of the movable seat 7 is fixedly installed on the outer surface of the slider 38, and an adjustment locking block 53 is detachably installed on the outer surface of the guide rod 52; wherein, the number of the swing arms 44, the gravity ball 45 and the connecting rod 46 in the centrifugal mechanism are all two, and the two swing arms 44 are symmetrically arranged. The rotating sleeve 43 is rotatably mounted on the outer surface of the spline sleeve 42. The design of the guide rod 52 and the adjustment locking block 53 provides stable guiding and locking functions for the movable seat 7. The guide rod 52 ensures the linearity and stability of the movable seat 7 during movement, while the adjustment locking block 53 allows the user to lock the position of the movable seat 7 as needed to prevent it from accidentally moving. The spline shaft 47 is fixed to the abutment seat 41, and a support frame mounted on the abutment seat 41 is fixed on the upper surface of the movable seat 7, and the abutment seat 41 is rotatably connected to the support frame. A connecting frame is fixed between the rotating sleeve 43 and the motor box 20.

[0063] At the same time, an opening and closing structure used in conjunction with the centrifugal mechanism is installed in the limiting tube 25, and the opening and closing structure includes a valve 49 rotatably installed inside the limiting tube 25, and a connecting shaft 50 extending to the outside of the limiting tube 25 is fixed to the top side of the valve 49, and a gear 51 is fixed to the top of the connecting shaft 50, and the outside of the gear 51 is meshed with a rack 54 fixed to the outer surface of the lower mold 2. The centrifugal mechanism is detachably installed to facilitate subsequent disassembly and assembly.

[0064] It should be noted that when dissipating heat, the exhaust fan 31 arranged via a double axis drives the fan blades and the spline shaft 47 to rotate respectively, the rotation of the spline shaft 47 drives the abutment seat 41, the rotation of the abutment seat 41 drives the gravity ball 45 to rotate through the swing arm 44, and when the gravity ball 45 rotates, it will produce centrifugal expansion outward for a certain distance, and then drive the motor box 20 to move outward through the connecting frame. At this time, the air outlet 37 on the limit tube 25 is connected to the positioning tube 26. At the same time, when the limit tube 25 is displaced, the valve 49 is driven to rotate through the transmission engagement of the rack 54 and the gear 51, and then the ventilation channel of the limit tube 25 is opened, thereby realizing cooling and heat dissipation of the interior of the upper mold 3.

[0065] It is worth noting that when the limiting tube 25 is inserted into the groove 36, the valve 49 is closed by the meshing of the rack 54 and the gear 51, and at the same time, the air outlet 37 and the positioning tube 26 are staggered to achieve a blocking effect.

[0066] When the present embodiment is in use, in the early stage of adjusting the thickness and diameter of the cavity, the displacement mechanism 40 pushes the support rod 16 to move outward, and the support rod 16 forms an expansion force outward. The support rod 16 supports and fixes the inner wall of the ring tube 15 through the expansion force. In the later stage, the support rod 16 moves inward and outward to fix and install the ring tubes 15 of different diameters. After the ring tube 15 is installed on the side of the support rod 16, the displacement mechanism 40 pushes the support rod 16 to move outward to squeeze and fix the ring tube 15, and then the upper mold 3 is installed on the lower mold 2. The upper mold 3 is installed inside the positioning hole 12 through the positioning tube 26. As the positioning tube 26 descends, the ring seat 27 and the support column The support block at the top of the mold 35 contacts with each other, and the ring seat 27 pushes the support column 35 to move downward through the support block. One end of the support column 35 is exposed from the bottom of the mounting hole 30, and one end of the support column 35 contacts the ground. The support column 35 installs the base 1 in a suspended state. After the support column 35 moves downward, the limit seat 19 is released. Under the push of the support mechanism 18, the slider 38 drives the limit seat 19 to move in the direction of the lower mold 2. The limit seat 19 pushes the limit tube 25 to enter the inside of the limit hole 28. The air outlet holes 37 are distributed in the inside of the positioning tube 26. One end of the limit tube 25 enters the inside of the groove 36 to support and fix the support column 35 at the same time.

[0067] After the upper mold 3 and the lower mold 2 are fixed, when the external material is fed through the feed pipe 5, the heating mechanism on the inner wall of the movable plate 4 heats the position of the upper mold 3. The heating mechanism is composed of an electric heating wire. The high temperature is generated by energizing the electric heating wire. The high temperature effectively avoids the phenomenon of material cooling and solidification when the material is fed through the feed pipe 5, thereby ensuring the fluidity of the material and facilitating the slow and even entry of the material into the lower mold 2. Later, when the heating mechanism is damaged, the movable plate 4 can be disassembled separately through the fixing bolts 6. After the movable plate 4 is disassembled, the heating mechanism can be replaced separately. The movable seat 7 is installed on the lower mold 2 through the limiting bolts 8. Later, the movable seat 7 can be disassembled by the limiting bolts 8. Later, after the material is formed, the double-axis The exhaust fan 31 is respectively driven to rotate the fan blades and the spline shaft 47, and the rotation of the spline shaft 47 drives the abutment seat 41, and the rotation of the abutment seat 41 drives the gravity ball 45 to rotate through the swing arm 44. When the gravity ball 45 rotates, it will expand outward by a certain distance centrifugally, and then drive the motor box 20 to move outward through the connecting frame. At this time, the air outlet 37 on the limiting tube 25 is connected with the positioning tube 26. At the same time, when the limiting tube 25 moves, the transmission meshing of the rack 54 and the gear 51 drives the valve 49 to rotate, and then the ventilation channel of the limiting tube 25 is opened, so as to realize the cooling and heat dissipation of the interior of the upper mold 3 and the cooling of the mold as a whole. After the cooling is completed, the movable tube 10 is pushed to the inside of the opening 9 for storage, so as to be convenient for heat preservation during the next injection.

[0068] When the formed material needs to be taken out later, the limiting tube 25 is separated from the groove 36. After the support column 35 loses support, the support column 35 shrinks inside the mounting hole 30 under the extrusion of the gravity of the lower mold 2 and the upper mold 3. As the support column 35 moves upward, the support column 35 pushes the positioning tube 26 to move upward. After the positioning tube 26 moves upward, the separation between the lower mold 2 and the upper mold 3 is opened, which is convenient for the later separation and opening of the upper mold 3 and the lower mold 2. The friction seat 29 contacts the ground later, so that the base 1 as a whole rotates with the friction seat 29 as the fulcrum. The friction seat 29 provides a limiting fixation for the rotating disk 23, and the material between the cavity 14 inside the lower mold 2 and the annular tube 15 rotates. The rotation of the material realizes the separation and falling off of the inner wall of the cavity 14 and the outer wall of the annular tube 15, thereby facilitating the removal of the material after forming.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
