Description

Technical Field

[0001] The present invention relates to the technical field of dental floss handle production molds, and more specifically to a dental floss handle production mold for dental floss manufacturing. Background Art

[0002] As the core component of dental floss products, the injection mold technology of dental floss handles directly affects product precision, production efficiency, and cost control. Traditional molds mostly adopt a two-plate structure and complete the separation of the molded parts through an ejector pin demolding mechanism. However, when dealing with complex structures such as special-shaped handles and elastic snap positions, it is easy to cause demolding deformation or surface scratches. Early mold designs often ignored the optimization of the parting line, resulting in flash and burrs on the joint surface of the dental floss handle, affecting the comfort and safety performance of use. During the use of existing dental floss handle production molds, there are some deficiencies, which are specifically as follows: Existing dental floss handle production molds are divided into an upper mold and a lower mold. During use, the upper and lower molds are separated, and then a specified volume of molten dental floss handle raw material is injected into the lower mold. Then, through the extrusion of the upper mold, the dental floss handle is formed. However, the existing molds cannot perform continuous processing during machining, and it is not convenient to demold the dental floss handle from the mold, so it is not convenient to use. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dental floss handle production mold for dental floss manufacturing to solve the problems existing in the above background art.

[0004] The present invention provides the following technical solution: A dental floss handle production mold for dental floss manufacturing, including a positioning component. A mold component is installed on the front of the positioning component, an extrusion molding component is installed on the front of the positioning component, and a demolding component is installed on the front of the positioning component. The positioning component includes a positioning base, a material collection box is fixedly connected to the top of the positioning base, a fixing plate is fixedly connected to the top of the positioning base, a quantitative conveying component is fixedly connected to the front of the fixing plate, a connecting flange is fixedly connected to the top of the quantitative conveying component, and a discharge pipe is fixedly connected to one side of the quantitative conveying component.

[0005] Further, the mold component includes a servo motor, a rotating mold is fixedly connected to the output shaft of the servo motor, a forming notch is opened on the outer side of the rotating mold, and a dental floss handle notch is opened at the bottom of the forming notch.

[0006] Further, the extrusion molding component includes a first positioning shaft, a first rotating shaft is fixedly connected to the back of the first positioning shaft, a first transmission gear is fixedly connected to the outer side of the first positioning shaft, and bevels are opened on both sides of the first transmission gear.

[0007] Further, the demolding assembly includes an air pump assembly, a demolding module is installed on the back of the air pump assembly, the air pump assembly includes an air pump body, an L-shaped air pipe is fixedly connected to the top of the air pump body, a positioning sleeve is fixedly connected to the back of the L-shaped air pipe, a second rotating shaft is fixedly connected to the back of the positioning sleeve, a first pipe is fixedly connected to the inside of the positioning sleeve, and a second pipe is fixedly connected to the outside of the first pipe.

[0008] Further, the demolding module includes a rotating ring, a positioning hole is formed in the front of the rotating ring, a third pipe is fixedly connected to the inside of the positioning hole, a second transmission tooth is fixedly connected to the outside of the rotating ring, and a jet gap is formed in the outside of the second transmission tooth.

[0009] Further, the cross-section of the rotating mold and the outer forming notch and the cross-section of the first positioning shaft and the first transmission tooth are meshed with each other, and the projected size of the demolding module is the same as the projected size of the first rotating shaft.

[0010] Further, the inner diameter of the first pipe is the same as the inner diameter of the L-shaped air pipe, the outer diameter of the positioning sleeve is in clearance fit with the diameter of the positioning hole, and the shape and size of the front of the jet gap are the same as the shape and size of the front of the first transmission tooth.

[0011] Further, the diameter of the third pipe is the same as the diameter of the second pipe, and the connection between the positioning sleeve and the rotating ring is positioned by a bearing.

[0012] The technical effects and advantages of the present invention: During the use of the present invention, the connecting flange is connected to the dental floss handle raw material melting device. After the dental floss handle raw material is melted, it is conveyed by the quantitative conveying assembly, enters the discharge pipe and then is guided by the discharge pipe to the inner part of the forming notch at the top outside the rotating mold. Then, the volume of the dental floss handle raw material injected into the forming notch is controlled to be the same as the volume of a single dental floss handle. At the same time, the rotating mold is driven to rotate by the servo motor, so that the rotating mold slowly rotates and the forming notch gradually rotates to the bottom of the discharge pipe, so that the forming notch is sequentially filled with the melted dental floss handle raw material. During the rotation of the rotating mold, due to the meshing of the forming notch outside the rotating mold and the bevel on the outside of the first positioning shaft, the bevel squeezes the inside of the forming notch after being matched with the corresponding forming notch, so that the dental floss handle raw material inside the forming notch enters the dental floss handle notch. And because the temperature of the bevel decreases after rotation, the dental floss handle in the dental floss handle notch is formed, so that the equipment can complete the cyclic processing of the dental floss handle, and the processing of the dental floss handle no longer depends on the cooperation of the upper and lower molds, ensuring the processing efficiency of the dental floss handle.

[0013] During the rotation of the rotary mold of the present invention, since the shapes and dimensions of the front projections of the first positioning shaft and the bevel angle are the same as those of the rotary ring and the front projection of the second transmission gear, the demolding module is driven to rotate relative to the air pump assembly during the rotation of the rotary mold. At the same time, gas is injected into the L-shaped air pipe through the operation of the air pump body, and then transmitted through the first pipe and the second pipe, and conveyed to the third pipe aligned with the second pipe, and then blown to the formed dental floss handle located in the notch of the dental floss handle, so that the dental floss handle falls from the notch of the dental floss handle into the jet notch, and then the continuous rotation of the second transmission gear conveys the dental floss handle to the collection box to collect the dental floss handle, realizing the automatic demolding and collection of the dental floss handle, ensuring the continuous processing of the dental floss handle, guaranteeing the processing efficiency and facilitating the use of the user.

[0023] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of each structure described in the following implementation manners are merely examples, and the dental floss handle production mold for dental floss manufacturing involved in the present invention is not limited to the structures described in the following implementation manners. All other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Referring to Figures 1 to 8 , the present invention provides a dental floss handle production mold for dental floss manufacturing, including a positioning component 1. A mold component 2 is installed on the front surface of the positioning component 1, an extrusion forming component 3 is installed on the front surface of the positioning component 1, and a demolding component 4 is installed on the front surface of the positioning component 1. The positioning component 1 includes a positioning base 101. A material receiving box 102 is fixedly connected to the top of the positioning base 101. A fixing plate 106 is fixedly connected to the top of the positioning base 101. A quantitative conveying component 103 is fixedly connected to the front surface of the fixing plate 106. A connecting flange 104 is fixedly connected to the top of the quantitative conveying component 103. A discharge pipe 105 is fixedly connected to one side of the quantitative conveying component 103.

[0025] In a preferred implementation manner, the mold component 2 includes a servo motor 201. The output shaft of the servo motor 201 is fixedly connected to a rotating mold 202. A forming notch 203 is provided on the outer side of the rotating mold 202. A dental floss handle notch 204 is provided at the bottom of the forming notch 203.

[0026] In a preferred implementation manner, the extrusion forming component 3 includes a first positioning shaft 301. A first rotating shaft 302 is fixedly connected to the back surface of the first positioning shaft 301. A first transmission gear 303 is fixedly connected to the outer side of the first positioning shaft 301. Bevel angles 304 are provided on both sides of the first transmission gear 303.

[0027] In a preferred embodiment, the demolding assembly 4 includes an air pump assembly 401. A demolding module 402 is mounted on the back of the air pump assembly 401. The air pump assembly 401 includes an air pump main body 4011. An L-shaped air pipe 4012 is fixedly connected to the top of the air pump main body 4011. A positioning sleeve 4014 is fixedly connected to the back of the L-shaped air pipe 4012. A second rotating shaft 4016 is fixedly connected to the back of the positioning sleeve 4014. A first pipe 4013 is fixedly connected to the inside of the positioning sleeve 4014. A second pipe 4015 is fixedly connected to the outside of the first pipe 4013. During the use process, connect the connecting flange 104 to the dental floss handle raw material melting device. After the dental floss handle raw material is melted, it is conveyed through the quantitative conveying assembly 103, enters the discharge pipe 105, and then is guided by the discharge pipe 105 to the inside of the forming notch 203 at the top outside the rotating mold 202. Then, control the volume of the dental floss handle raw material injected into the forming notch 203 to be the same as the volume of a single dental floss handle. At the same time, drive the rotating mold 202 to rotate through the operation of the servo motor 201, so that the rotating mold 202 slowly rotates and the forming notch 203 gradually rotates to the bottom of the discharge pipe 105, so that the forming notch 203 is sequentially filled with the melted dental floss handle raw material. During the rotation of the rotating mold 202, since the forming notch 203 on the outside of the rotating mold 202 meshes with the bevel 304 on the outside of the first positioning shaft 301, after the bevel 304 cooperates with the corresponding forming notch 203, the bevel 304 squeezes the inside of the forming notch 203, so that the dental floss handle raw material inside the forming notch 203 enters the dental floss handle notch 204. And because the temperature of the bevel 304 decreases after rotation, the dental floss handle in the dental floss handle notch 204 is formed, enabling the device to complete the cyclic processing of the dental floss handle, making the processing of the dental floss handle no longer rely on the cooperation of the upper and lower molds, and ensuring the processing efficiency of the dental floss handle.

[0028] In a preferred embodiment, the demolding module 402 includes a rotating ring 4021. A positioning hole 4022 is formed in the front surface of the rotating ring 4021. A third pipe 4023 is fixedly connected to the inner side of the positioning hole 4022. A second transmission gear 4024 is fixedly connected to the outer side of the rotating ring 4021. An air jet notch 4025 is formed in the outer side of the second transmission gear 4024. During the rotation of the rotating mold 202, since the shapes and sizes of the front projections of the first positioning shaft 301 and the bevel angle 304 are the same as those of the front projections of the rotating ring 4021 and the second transmission gear 4024, the rotation of the rotating mold 202 drives the demolding module 402 to rotate relative to the air pump assembly 401. At the same time, the air pump body 4011 works to inject gas into the L-shaped air pipe 4012, and then it is transmitted through the first pipe 4013 and the second pipe 4015 and delivered to the third pipe 4023 aligned with the second pipe 4015. Then, the formed dental floss handle located in the dental floss handle notch 204 is blown, so that the dental floss handle falls from the dental floss handle notch 204 into the air jet notch 4025. Then, the continuous rotation of the second transmission gear 4024 conveys the dental floss handle to the material collecting box 102 for collection of the dental floss handle, realizing the automatic demolding and collection of the dental floss handle, ensuring the continuous processing of the dental floss handle, guaranteeing the processing efficiency and being convenient for the user to use.

[0029] In a preferred embodiment, the cross-section of the rotating mold 202 and the outer forming notch 203 meshes with the cross-section of the first positioning shaft 301 and the first transmission gear 303, and the projected dimension of the demolding module 402 is the same as the projected dimension of the first rotating shaft 302.

[0030] In a preferred embodiment, the inner diameter of the first pipe 4013 is the same as the inner diameter of the L-shaped air pipe 4012, and there is a clearance fit between the outer diameter of the positioning sleeve 4014 and the diameter of the positioning hole 4022. The shape and size of the front surface of the air jet notch 4025 are the same as the shape and size of the front surface of the first transmission gear 303.

[0031] In a preferred embodiment, the diameter of the third pipe 4023 is the same as the diameter of the second pipe 4015, and the connection between the positioning sleeve 4014 and the rotating ring 4021 is positioned by a bearing.

[0032] Working principle of the present invention: During use, connect the connecting flange 104 to the dental floss handle raw material melting device. After the dental floss handle raw material is melted, it is transported through the quantitative conveying component 103, enters the discharge pipe 105, and then is guided by the discharge pipe 105 to the inside of the forming notch 203 at the top outside the rotating mold 202. Then, control the volume of the dental floss handle raw material injected into the forming notch 203 to be the same as the volume of a single dental floss handle. At the same time, drive the rotating mold 202 to rotate through the operation of the servo motor 201, so that the rotating mold 202 rotates slowly, causing the forming notch 203 to gradually rotate to the bottom of the discharge pipe 105, and the forming notch 203 is sequentially filled with the melted dental floss handle raw material. During the rotation of the rotating mold 202, since the forming notch 203 on the outside of the rotating mold 202 meshes with the bevel 304 on the outside of the first positioning shaft 301, after the bevel 304 cooperates with the corresponding forming notch 203, the dental floss handle raw material inside the forming notch 203 is extruded into the dental floss handle notch 204 by the bevel 304. And because the temperature of the bevel 304 decreases after rotation, the dental floss handle in the dental floss handle notch 204 is formed, enabling the device to complete the cyclic processing of the dental floss handle, eliminating the need for the cooperation of upper and lower molds in dental floss handle processing, and ensuring the processing efficiency of the dental floss handle; During the rotation of the rotating mold 202, since the shapes and sizes of the front projections of the first positioning shaft 301 and the bevel 304 are the same as those of the rotating ring 4021 and the second transmission tooth 4024, the rotation of the rotating mold 202 drives the demolding module 402 to rotate relative to the air pump assembly 401. At the same time, gas is injected into the L-shaped air pipe 4012 through the operation of the air pump body 4011, and then transmitted through the first pipe 4013 and the second pipe 4015, and conveyed to the third pipe 4023 aligned with the second pipe 4015, and then blown on the dental floss handle that has been formed in the dental floss handle notch 204, causing the dental floss handle to fall from the dental floss handle notch 204 into the air jet notch 4025. Then, through the continuous rotation of the second transmission tooth 4024, the dental floss handle is conveyed to the collection box 102 for collection, realizing the automatic demolding and collection of the dental floss handle, ensuring the continuous processing of the dental floss handle, and guaranteeing the processing efficiency for the convenience of the user.
