Description

Technical Field

[0001] This invention relates to the field of magnetic component processing technology, specifically a demolding device. Background Technology

[0002] Magnetic components typically consist of windings and a magnetic core. They are essential power electronic devices for energy storage, energy conversion, and electrical isolation. During production, magnetic components require potting and encapsulation.

[0003] The application document with application number 202121543521.3 discloses a driver local potting demolding device, and specifically discloses that by pressing the tooling base plate, the support rod can retract to eject the insulating gasket, which has the characteristics of improving demolding efficiency and high reliability.

[0004] In the aforementioned application documents, the glue dispensing tank is set on the tooling base plate, and an insulating gasket is set inside the glue dispensing tank. Therefore, both the glue dispensing tank and the insulating gasket are set on the tooling base plate. If the equipment of the entire workbench needs to be changed when processing finished products of different sizes, the requirements for the type of equipment are relatively strict. In addition, since a certain force is applied when the top plate pushes out the finished product, if there are some adhesions in the finished product, directly pushing it out may cause defective products to appear. Summary of the Invention

[0005] The purpose of this invention is to provide a demolding device.

[0006] The technical problem solved by this invention is as follows: Since the glue dispensing tank is set on the tooling base plate and an insulating gasket is set inside the glue dispensing tank, both the glue dispensing tank and the insulating gasket are set on the tooling base plate. The above-mentioned devices are integrated into one unit. If products of different sizes are processed, different equipment needs to be changed, resulting in a large number of equipment types required, high costs, and a large footprint. At the same time, since the ejection component directly applies force to the top plate, if some parts of the finished product are stuck to the mold, directly ejecting it will cause defective products to appear, increasing costs.

[0007] The present invention can be achieved by the following technical solution: a demolding device, including a mold base, on which a glue-pouring mold is installed by a fixing structure, and an air vent is provided at the bottom of the glue-pouring mold. When the glue-pouring mold is installed on the mold base by the fixing structure, the air vent is connected to an external air intake component through a sealing component.

[0008] A further technical improvement of the present invention is that: the sealing component includes a rubber ring located at the end of the air inlet; the external air intake component includes an air intake plug with a sealing ring fixed to its outer ring; the sealing ring is groove-shaped; when the glue-pouring mold is installed on the mold base through a fixing structure, the rubber ring is pressed tightly against the sealing ring, and the air intake plug is connected to the air inlet.

[0009] A further technical improvement of the present invention is that a support spring is fixed inside the sealing ring, and a sealing slide plate is fixed at the end of the support spring and the sealing slide plate and the sealing ring are slidably connected. When the glue potting mold is installed on the mold base through the fixing structure, the rubber ring is pressed tightly on the sealing slide plate.

[0010] A further technical improvement of the present invention is that: a protective shell is symmetrically fixed on the mold base, and a side limiting seat is symmetrically fixed on the side of the protective shell, the side limiting seat surrounds the mold placement area, and a region groove is opened on the side of the protective shell near the side limiting seat.

[0011] A further technical improvement of the present invention is that: the fixed structure includes a rotating groove, the rotating groove is symmetrically opened on the mold base, a hinge shaft is fixed inside the rotating groove, a clamping member is rotatably arranged on the hinge shaft, the clamping member passes through the rotating groove and a rotating component is provided at the bottom of the clamping member.

[0012] A further technical improvement of the present invention is that the clamping member is "L" shaped, and when the clamping member clamps the dispensing mold under the action of the rotating component, the L-shaped bend of the clamping member is stuck on the dispensing mold.

[0013] A further technical improvement of the present invention is that: the rotating component includes a pushing cylinder, a connecting rod is rotatably provided at the moving end of the pushing cylinder, a hinge seat is rotatably provided at the end of the connecting rod away from the pushing cylinder, the hinge seat is rotatably connected to the rotating component through a rotating seat, and the hinge seat is slidably connected to the mold base.

[0014] A further technical improvement of the present invention is that: a slider is fixed on the hinge seat, and a mounting base is fixed at the bottom of the mold base, and a sliding groove is opened at the bottom of the mounting base, and the slider and the sliding groove are slidably connected.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This application allows for the selection of appropriate size and shape of the dispensing mold, enabling the replacement of the finished product's size and type at any time. The dispensing mold is then placed within the limiting area of ​​the four sets of side limiting seats. Applying external force compresses the mold, pressing the rubber ring tightly onto the sealing slide plate. This compresses the support spring until it reaches its lowest point, activating the cylinder and extending it outwards by a certain length. The connecting rod then drives the hinge seat to slide. At this point, the clamping component rotates around the hinge axis under the action of the rotating seat, clamping the dispensing mold. Releasing the external force then secures the dispensing mold. By utilizing the clamping action, both the mold and the rubber ring are fixed. Furthermore, at the end of the dispensing process, air can be introduced through the air inlet plug and blown onto the bottom of the finished product through the air outlet, gradually detaching it from the mold and achieving demolding. Since gas has a certain degree of flexibility relative to the mechanical structure, this process protects the finished product, reduces loss, and lowers costs.

[0017] 2. If the dispensing mold needs to be replaced, after the clamping part is inserted into the protective shell, the clamping force on the dispensing mold is released. At this time, the support spring provides an upward elastic force to lift the dispensing mold from the mold base. If the clamping part contacts the bottom of the dispensing mold at this time, due to the shape of the clamping part, it will lift the dispensing mold, which is convenient for replacing the dispensing mold.

[0027] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0028] Please see Figure 1-7 As shown, a demolding device includes a mold base 1, on which a glue-pouring mold 2 is detachably mounted. The glue-pouring mold 2 has a glue-pouring groove 3. After being squeezed by the corresponding upper mold, the raw material is poured into the glue-pouring groove 3 to realize the production of the desired finished product. At the same time, the glue-pouring mold 2 is detachable, and the glue-pouring mold 2 of the corresponding size and shape can be selected as needed to realize the function of rapid cutting line and has high adaptability.

[0029] Since the finished product is lifted by direct external force when passing through the top plate, if some parts are stuck together, it will cause damage to the finished product and result in defective products. Therefore, an air vent 11 is provided at the bottom of the glue-pouring mold 2. The air vent 11 is connected to an external gas component through a sealing component. By blowing gas into the bottom of the glue-pouring mold 2, a more flexible gas demolding method is used when the finished product needs to be demolded after processing. The gas contacts the bottom of the finished product and blows it upward. If some parts are stuck together, the gas blowing is done in stages, so the finished product will gradually separate from the stuck parts, reducing the loss rate, ensuring the quantity of finished products, and reducing production losses.

[0030] A protective shell 4 is symmetrically fixed on the mold base 1. Side limiting seats 12 are symmetrically fixed on the sides of the protective shell 4 to position the glue dispensing mold 2. The glue dispensing mold 2 is placed in the limiting area of ​​the four sets of side limiting seats 12, that is, the side limiting seats 12 form a mold placement area to fix the position of the glue dispensing mold 2. At the same time, a region groove is opened on the side of the protective shell 4 near the glue dispensing mold 2, that is, a region groove is set on the side near the side limiting seats 12 to realize the rotation of the fixing structure. The fixing structure is used to fix the glue dispensing mold 2, prevent the glue dispensing mold 2 from moving longitudinally, and apply pressure to the sealing component through the air vent 11 to ensure the sealing of the sealing component.

[0031] Firstly, the fixing structure includes rotating grooves. Rotating grooves are symmetrically formed on the mold base 1, and a hinge shaft 15 is fixed to each rotating groove. A clamping member 13 is rotatably mounted on the hinge shaft 15, passing through the rotating grooves. A rotating component is located at the bottom of the clamping member 13 to drive its rotation. The clamping member 13 is L-shaped; that is, when the clamping member 13 clamps the dispensing mold 2, the L-shaped bend of the clamping member 13 is located above the dispensing mold 2, thus fixing the dispensing mold 2. Before the dispensing mold 2 is placed on the corresponding side limiting seat 12, the rotating component is used to drive the clamping member 13 to rotate around the hinge shaft 15. This allows the L-bend of the clamping member 13 to be located inside the protective shell 4. Then, the dispensing mold 2 is placed on the corresponding side limit seat 12 by applying external force. Subsequently, the clamping member 13 is pushed in the opposite direction by the rotating component, thereby fixing the dispensing mold 2 by using the L-bend of the clamping member 13. In this application, the fixing effect of the clamping member 13 is used to replace the application of external force, ensuring that the dispensing mold 2 can be pressed tightly on the sealing component. During this process, the rotation directions of the two symmetrically arranged clamping members 13 are also symmetrical. The rotation direction of the clamping member 13 is controlled by the rotating component to ensure the consistency of clamping.

[0032] The rotating component is designed to ensure consistency when the clamping member 13 is clamped. Therefore, the rotating component includes a push cylinder 8, which is fixedly mounted on the mold base 1. A push support seat 9 is fixed to the moving end of the push cylinder 8. A connecting rod 10 is rotatably mounted on the push support seat 9. The end of the connecting rod 10 away from the push cylinder 8 is rotatably mounted on a hinge seat 7. A rotating seat 16 is rotatably mounted on the side of the hinge seat 7, and the clamping member 13 is rotatably mounted on the other end of the rotating seat 16. The hinge seat 7 and the mold base 1... The sliding connection ensures that when the cylinder 8 is activated, the connecting rod 10 is activated, causing the connecting rod 10 to slide the hinge seat 7 on the mold base 1. When the mold base 1 slides, it will cause one end of the rotating seat 16 to rotate. Since the clamping member 13 is rotatably connected to the mold base 1 through the hinge shaft 15, the angle of the rotating seat 16 will change with the rotation of the clamping member 13, thereby driving the clamping member 13 to rotate. At this time, the clamping member 13 can clamp and fix the dispensing mold 2.

[0033] A slider 14 is fixed above the hinge seat 7, and a mounting base 5 is fixed at the bottom of the mold base 1. A groove 6 is provided below the mounting base 5. The slider 14 and the groove 6 are slidably connected, thereby enabling the hinge seat 7 to move laterally. In this application, the push support seat 9 is shaped like an outward octagon, and the connecting rod 10 rotates at the end of the push support seat 9. The sliding connection between the slider 14 and the groove 6 is used to enable the hinge seat 7 to slide under the action of the connecting rod 10. The shape of the push support seat 9 is used to symmetrically hinge the connecting rod 10, achieving consistency when the clamping member 13 is clamped, and ensuring the stability of clamping the dispensing mold 2.

[0034] The sealing assembly is a component used to seal the air inlet 11 and the external air intake assembly. Specifically, it includes a rubber ring 17, which is fixed to the outer ring of the end of the air inlet 11. The external air intake assembly includes an air inlet plug 18, which is connected to an air intake pipe. The air intake pipe is connected to an air intake pump to allow air to enter. A sealing ring 19 is fixed to the periphery of the air inlet plug 18. The sealing ring 19 has a groove in the middle. When the rubber ring 17 is pressed tightly into the groove of the sealing ring 19, the rubber ring 17 is pressed tightly into the inside of the sealing ring 19 because it is made of rubber. At this time, the air inlet plug 18 and the air inlet 11 are connected to achieve a sealing effect. Under the clamping action of the clamping member 13 on the dispensing mold 2, the rubber ring 17 is pressed tightly onto the sealing ring 19.

[0035] A support spring 21 is fixed at the bottom of the groove of the sealing ring 19, and a sealing slide plate 20 is fixed at the end of the support spring 21. The sealing slide plate 20 and the sealing ring 19 are slidably connected. The sealing slide plate 20 is a smooth slide plate used to seal with the rubber ring 17. In this application, when the clamping member 13 clamps, the rubber ring 17 is pressed tightly on the sealing slide plate 20. At this time, the support spring 21 is pressed to its lowest end. When the dispensing mold 2 is replaced, once the clamping member 13 rotates into the protective shell 4, the air vent 11 will be lifted by the action of the support spring 21. At this time, the dispensing mold 2 is lifted. At the same time, since the end of the clamping member 13 is arc-shaped, the clamping member 13 gradually contacts the bottom of the dispensing mold 2. By rotating the clamping member 13, the dispensing mold 2 is gradually lifted.

[0036] In use, this invention first selects a dispensing mold 2 of appropriate size and shape, allowing for easy replacement of the finished product's size and type. Then, the dispensing mold 2 is placed within the limiting areas of the four sets of side limiting seats 12. Applying external force compresses the dispensing mold 2, causing the rubber ring 17 to press firmly against the sealing slide plate 20, thereby compressing the support spring 21 until it is pressed to its lowest point. At this point, the air inlet 11 connects to the air inlet plug 18, establishing an air passage and driving the cylinder 8 to extend outwards by a certain length. The connecting rod 10 then... The movable hinge seat 7 slides, and the clamping member 13 rotates around the hinge axis 15 under the action of the rotating seat 16, so that the clamping member 13 is clamped on the glue-pouring mold 2. At this time, the external force is released to realize the installation and fixation of the glue-pouring mold 2. When the glue-pouring production process is finished, gas is introduced through the air inlet plug 18 and blown through the air outlet 11 to the bottom of the finished product, so that the finished product is gradually separated from the glue-pouring mold 2, realizing the demolding of the finished product. Since the gas has a certain degree of flexibility relative to the mechanical structure, it protects the production of the finished product, reduces the loss rate, and reduces costs.

[0037] If the dispensing mold 2 needs to be replaced or cleaned, simply use the push cylinder 8 to retract a certain length inward. The connecting rod 10 drives the hinge seat 7 to slide. At this time, the clamping member 13 rotates around the hinge axis 15 under the action of the rotating seat 16, so that the clamping member 13 rotates into the protective shell 4. At this time, the support spring 21 provides an upward elastic force, which lifts the dispensing mold 2 from the mold base 1. If the clamping member 13 contacts the bottom of the dispensing mold 2 at this time, due to the shape of the clamping member 13, it will lift the dispensing mold 2, making it easy to replace the dispensing mold 2.
