Technical Field

[0001] This invention belongs to the field of molding technology, and in particular relates to a molding device for enameled wire winding spools. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. After production, enameled wire needs to be collected using spools, which are a type of winding bobbin. Most of them are made of plastic, and currently, molds are often used to manufacture spools.

[0003] Currently, most mold manufacturing uses the casting method, and existing casting methods mostly involve casting from the top. This method may result in gas not being expelled during the casting process, which could affect the quality of the spool. Summary of the Invention

[0004] The purpose of this invention is to provide a device for forming enameled wire winding spools to solve the problem of gas not being expelled during the upper casting process.

The feeding column has multiple discharge holes communicating with the storage cavity around its circumference. The discharge holes fill the molding die with molding material. The pressure relief device is located at the upper end of the feeding column. When the material inside the storage cavity needs to be recycled, the pressure relief device connects the storage cavity with the outside. The leak prevention device controls the communication between the discharge hole and the molding die.

[0008] Furthermore, the pressure relief device includes a sliding mounting hole, a movable frame, a first spring, an exchange hole, a connecting rod, and a baffle. The sliding mounting hole and the exchange hole are disposed on the feeding column and are connected.

[0010] Furthermore, the molding die includes a combined half-die, a molding cavity, an upper expansion cavity, and a lower expansion cavity. The two combined half-die are arranged to form an integral mold and are fitted on the outside of the feeding column. The molding cavity is located between the combined half-die and the feeding column. The venting annular groove is located at the upper end of the combined half-die and communicates with the upper expansion cavity. The upper expansion cavity and the lower expansion cavity are located on the combined half-die. The driving device is located inside the lower expansion cavity, and the driven device is located inside the upper expansion cavity.

[0011] Furthermore, the driving device includes a lower movable semi-arc plate, a connecting sleeve, a third spring, a connecting bolt, and a first pushing semi-ring. The lower movable semi-arc plate slides inside the lower expansion cavity. The connecting sleeve is disposed to connect the combined half mold and the lower expansion cavity. A third spring is provided between the connecting sleeve and the lower movable semi-arc plate. The first pushing semi-ring is connected to the lower movable semi-arc plate through the connecting bolt. The first pushing semi-ring drives the driven device to expand the upper expansion cavity through a transmission device.

[0012] Furthermore, the driven device includes an upper movable semi-arc plate, a second connecting bolt, a second pushing semi-ring, an exhaust hole, and a sealing plate.

[0014] The advantages of this invention are:

[0015] This invention uses a feeding device to inject hot-melt material into a molding die. As the amount of material inside the molding die increases, the material gradually flows from the molding die into the feeding device. As the amount of material inside the feeding device increases, the driving device and the driven device move inside the molding die, expanding the space of the molding die for the material injection into the baffles at both ends of the spool. The transmission device makes the driven device and the driving device move synchronously. When the molding die is full of material, the excess material inside the feeding device will flow back into the feeding device, but the material inside the molding die will not be discharged outward. During the process of injecting material into the molding die, there are exhaust annular grooves at the top of the feeding device and the molding die to prevent gas from being left unremoved.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figure 1-6 As shown, an enameled wire winding spool forming device includes a feeding device 1 and a forming mold 2. The forming mold 2 is fitted onto the outer end of the feeding device 1. The feeding device 1 fills the forming mold 2 with forming material. The device is characterized in that the upper end of the forming mold 2 on the feeding device 1 is provided with an exhaust annular groove 3, the lower end of the forming mold 2 is provided with a driving device 4, the upper end of the forming mold 2 is provided with a driven device 5, and the forming mold 2 is provided with a transmission device 6 for connecting the driving device 4 and the driven device 5. The forming mold 2 is a combination mold for easy demolding and recycling.

[0027] The hot melt material is injected into the molding mold 2 by the feeding device. As the amount of material inside the molding mold 2 increases, the material gradually enters the feeding device 1 from the molding mold 2. As the amount of material inside the feeding device 1 increases, the driving device 4 and the driven device 5 move inside the molding mold 2 to expand the space of the molding mold 2 for the molding of the baffles at both ends of the spool. The transmission device 6 makes the driven device 5 and the driving device 4 move synchronously. When the molding mold 2 is full of material, the excess material inside the feeding device 1 will flow back into the feeding device, but the material inside the molding mold 2 will not be discharged outward. During the process of injecting material into the molding mold 2, the feeding device 1 and the upper end of the molding mold 2 have an exhaust annular groove 3 to prevent gas from being left unremoved.

[0028] Among them, such as Figure 1-6As shown, the feeding device 1 includes a feeding column 1-1, a storage cavity 1-2, an inlet / outlet 1-3, a discharge hole 1-4, a pressure relief device 1-5, and a leak prevention device 1-6. The feeding column 1-1 has a storage cavity 1-2 inside. The lower end of the feeding column 1-1 has an inlet / outlet 1-3 that communicates with the storage cavity 1-2. The feeding column 1-1 has multiple discharge holes 1-4 that communicate with the storage cavity 1-2 around its circumference. The discharge holes 1-4 fill the molding die 2 with molding material. The pressure relief device 1-5 is located at the upper end of the feeding column 1-1. When the material inside the storage cavity 1-2 needs to be recycled, the pressure relief device 1-5 makes the storage cavity 1-2 communicate with the outside. The leak prevention device 1-6 controls the communication between the discharge hole 1-4 and the molding die 2.

[0029] Material is first injected into the storage cavity 1-2 through the inlet / outlet 1-3. As the material in the storage cavity 1-2 exceeds the discharge hole 1-4, it enters the molding die 2 through the discharge hole 1-4 for molding. During the replenishment of material in the storage cavity 1-2, the pressure relief device 1-5 is closed. When the storage cavity 1-2 needs to be discharged, the pressure relief device 1-5 is open to connect the storage cavity 1-2 with the outside, facilitating the discharge of material. The cavity in the storage cavity 1-2 above the discharge hole 1-4 can also accelerate the discharge of material. When the molding die 2 does not need to be filled with material, the molding die 2 drives the anti-leakage device 1-6 to block the discharge hole 1-4 to prevent the material in the molding die 2 from flowing back into the storage cavity 1-2. After the molding die 2 is demolded, the anti-leakage device 1-6 releases the blockage of the discharge hole 1-4.

[0030] Among them, such as Figure 1-6 As shown, the pressure relief device 1-5 includes a sliding mounting hole 1-5-1, a movable frame 1-5-2, a first spring 1-5-3, an exchange hole 1-5-4, a connecting rod 1-5-5, and a baffle 1-5-6. The sliding mounting hole 1-5-1 and the exchange hole 1-5-4 are disposed on the feeding column 1-1 and are connected. The movable frame 1-5-2 slides inside the sliding mounting hole 1-5-1 and is located between the movable frame 1-5-2 and the sliding mounting hole 1-5-1. The baffle 1-5-6 is disposed on the movable frame 1-5-2 via the connecting rod 1-5-5 and slides inside the exchange hole 1-5-4. The exchange hole 1-5-4 is connected to the storage chamber 1-2.

[0031] When material is injected into storage chamber 1-2, baffle 1-5-6 will block exchange hole 1-5-4 under pressure. When material is discharged, baffle 1-5-6 will move downward under air pressure to expose exchange hole 1-5-4.

[0032] Among them, such as Figure 1-6As shown, the anti-leakage device 1-6 includes a first sliding cavity 1-6-1, a moving disk 1-6-2, a connecting column 1-6-3, a second spring 1-6-4, and a limiting seat 1-6-6. The first sliding cavity 1-6-1 is disposed inside the feeding column 1-1. The moving disk 1-6-2 slides inside the first sliding cavity 1-6-1. The connecting column 1-6-3 is disposed on the moving disk 1-6-2. The second spring 1-6-4 is disposed on the first sliding cavity 1-6-1 and the moving disk 1-6-2. The transmission device 6 drives the second spring 1-6-4 to move through the limiting seat 1-6-6. The connecting column 1-6-3 is provided with a moving sleeve 1-6-5 for blocking the discharge hole 1-4, which slides inside the storage cavity 1-2.

[0033] As the amount of material inside the molding die 2 increases, the material will compress the drive device 4 to move. The moving drive device 4 drives the limit seat 1-6-6 to move through the transmission device 6. The limit seat 1-6-6 drives the moving sleeve 1-6-5 to move through the connecting column 1-6-3 to block the discharge hole 1-4 to prevent waste from adding more material and to avoid leakage of material inside the molding die 2.

[0034] Among them, such as Figure 1-6 As shown, the molding die 2 includes a combined half-die 2-1, a molding cavity 2-2, an upper expansion cavity 2-3, and a lower expansion cavity 2-4. The two combined half-die 2-1 form an integral mold set on the outside of the feed post 1-1. The molding cavity 2-2 is located between the combined half-die 2-1 and the feed post 1-1. The venting annular groove 3 is located at the upper end of the combined half-die 2-1 and communicates with the upper expansion cavity 2-3. The upper expansion cavity 2-3 and the lower expansion cavity 2-4 are located on the combined half-die 2-1. The driving device 4 is located inside the lower expansion cavity 2-4, and the driven device 5 is located inside the upper expansion cavity 2-3.

[0035] Material is added to the molding cavity 2-2 through the discharge hole 1-4. As the amount of material inside the molding cavity 2-2 increases, the drive device 4 will be pressured and move downward to expand the lower expansion cavity 2-4. The drive device 4 drives the driven device 5 to move through the transmission device 6, so that the upper expansion cavity 2-3 is also expanded. While the molding cavity 2-2 is replenished with material, gas is discharged from the driven device 5.

[0036] Among them, such as Figure 1-6As shown, the driving device 4 includes a lower movable semi-arc plate 4-1, a connecting sleeve 4-2, a third spring 4-3, a connecting bolt 4-4, and a first pushing semi-ring 4-5. The lower movable semi-arc plate 4-1 slides inside the lower expansion cavity 2-4. The connecting sleeve 4-2 is arranged to connect the combined semi-mold 2-1 and the lower expansion cavity 2-4. The third spring 4-3 is provided between the connecting sleeve 4-2 and the lower movable semi-arc plate 4-1. The first pushing semi-ring 4-5 is connected to the lower movable semi-arc plate 4-1 through the connecting bolt 4-4. The first pushing semi-ring 4-5 drives the driven device 5 to expand the upper expansion cavity 2-3 through the transmission device 6.

[0037] When the lower movable semi-arc plate 4-1 is subjected to material pressure, it will move downwards. The moving lower movable semi-arc plate 4-1, through the connecting bolt 4-4, drives the first pushing semi-ring 4-5 to move. The first pushing semi-ring 4-5 drives the driven device 5 to expand the upper expansion cavity 2-3 through the transmission device 6.

[0038] Among them, such as Figure 1-6 As shown, the driven device 5 includes an upper movable semi-arc plate 5-1, a second connecting bolt 5-2, a second pushing semi-ring 5-3, an exhaust hole 5-4, and a sealing plate 5-5. The upper movable semi-arc plate 5-1 slides inside the upper expansion cavity 2-3. The upper movable semi-arc plate 5-1 is connected to the second connecting bolt 5-2 and the second pushing semi-ring 5-3. The upper movable semi-arc plate 5-1 is provided with an exhaust hole 5-4 so that the upper expansion cavity 2-3 communicates with the outside. The feed column 1-1 is provided with a sealing plate 5-5 to seal the exhaust hole 5-4. The second pushing semi-ring 5-3 is connected to the first pushing semi-ring 4-5 through a transmission device 6.

[0039] The second push semi-ring 5-3 drives the upper moving semi-arc plate 5-1 to move and expand the upper expansion cavity 2-3 through the second connecting bolt 5-2, and the gas is discharged through the exhaust hole 5-4.

[0040] Among them, such as Figure 1-6 As shown, the transmission device 6 includes a support mounting rod 6-1, a first rack 6-2, a fixed gear 6-3, and a second rack 6-4. The support mounting rod 6-1 is mounted on the reciprocating moving device and has a combined half-mold 2-1. The fixed gear 6-3 is mounted on the support mounting rod 6-1. The first rack 6-2 is mounted on the first pushing half-ring 4-5, and the second rack 6-4 is mounted on the second pushing half-ring 5-3. The first rack 6-2 and the second rack 6-4 slide on the support mounting rod 6-1. Both the first rack 6-2 and the second rack 6-4 mesh with the fixed gear 6-3. A limiting seat 1-6-6 is mounted on the first rack 6-2.

[0041] The first pushing half-ring 4-5 moves, driving the first rack 6-2 to move. The first rack 6-2, through the fixed gear 6-3 and the second rack 6-4, drives the second pushing half-ring 5-3 to move. When the molding die 2 is demolded, the moving device drives the combined half-die 2-1 to move to both sides through the support mounting rod 6-1. The moving support mounting rod 6-1 drives the first rack 6-2 to move. The first rack 6-2 drives the limit seat 1-6-6 to move and slide out from the connecting column 1-6-3. Without the limit seat 1-6-6, the connecting column 1-6-3 moves upward under the action of the second spring 1-6-4. The connecting column 1-6-3 drives the moving sleeve 1-6-5 to expose the discharge hole 1-4.
