Description

Technical Field

[0001] This utility model relates to the field of mold ejection technology, specifically to an ejection device for injection-molded 1 / 4 arc pipe products. Background Technology

[0002] Demolding is a general term for the devices in a mold used to push the molded product out of the mold cavity. The product being demolded is injection molded. Injection-molded arc pipe fittings are plastic pipe fittings formed by injection molding. Injection molding is used for molding rubber and plastic products. The material is heated to a molten state and then injected into a mold under pressure. After cooling, it forms the desired shape. Injection-molded 1 / 4 arc pipe fittings are pipe fittings made by injection molding. Their characteristic is that they have a 1 / 4 arc shape. This shape is easy to install and provides a good grip and comfort.

[0003] The current demolding device still has some shortcomings, such as the device being inconvenient for demolding, or demolding easily causing damage to the product:

[0004] To overcome the problems of low demolding efficiency and easy damage, the existing Chinese patent (publication number: CN215039751U) discloses an integrated demolding and ejection injection mold for arc-shaped hollow injection molded parts. By holding the handle, the connecting column engaged on the side of the connecting rod rotates. The second threaded column rotates with the connecting column in the fixed column groove opened on the side. During the rotation, the threads on the surface of the second threaded column cause the meshing first threaded column to slowly rise, thereby slowly raising the injection mold of the injection equipment that bears the weight on the top of the first threaded column. This effectively solves the problem that the mold of arc-shaped hollow injection molded parts is easily damaged by prying with a skid for a long time, and extends the service life of the mold.

[0005] However, the demolding devices currently in use still have certain shortcomings. The demolding efficiency in the above document is relatively high, but it is inconvenient to demold the product inside the mold. The product usually sticks to the mold after cooling. If it is ejected directly, it is easy to damage the product. Secondly, the mold cavity is inconvenient to clean after the product is formed, making it more troublesome to use. Therefore, it is necessary to improve the existing structure. Utility Model Content

[0006] The purpose of this utility model is to provide a demolding device for injection-molded 1 / 4 arc tube fittings, so as to solve the problems in the background art where the demolding effect of the demolding device may be insufficient, affecting product quality, and the demolding device is inconvenient to clean the cavity, which can easily affect product processing efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a molding device for ejecting 1 / 4 arc-shaped injection molded pipe fittings, comprising a main body of equipment, wherein a mold is internally connected to the upper surface of the main body of equipment.

[0008] The mold is equipped with a motor, and a large gear is fixed to the output end of the motor. A rotating rod is rotatably connected to the side of the large gear away from the motor through a one-way bearing. Cams are fixed to the surface and end of the rotating rod. The mold is equipped with an ejection mechanism to facilitate the demolding of pipe fittings.

[0009] The large gear is meshed with a small gear at its bottom, and the mold is also equipped with a blower mechanism for easy cleaning.

[0010] Furthermore, the ejection mechanism includes an ejector block, which slides through the cavity of the mold. A rubber wheel is rotatably connected to the inner side of the cam, and the rubber wheel is in close contact with the ejector block.

[0011] Furthermore, a first transmission wheel is fixed to the surface of the rotating rod near the cam, a transmission belt is connected to the surface of the first transmission wheel, and a second transmission wheel is connected to the inner side of the transmission belt away from the first transmission wheel. The first transmission wheel, the transmission belt, and the second transmission wheel are connected in a transmission manner.

[0012] Furthermore, a gear rod is fixed to the two sides of the transmission wheel, the gear rod rotates inside the mold, and a transmission gear is meshed with the side of the gear rod. The second top block slides through the cavity of the mold away from the first top block.

[0013] Furthermore, a toothed plate is connected to the side of the top block two near the transmission gear, and a sliding block is fixed to the side of the toothed plate. The toothed plate and the transmission gear are meshed together, and the sliding block slides inside the top block two.

[0014] Furthermore, the blower mechanism includes a manual pump, which is installed inside the mold. The pinion rotates through the manual pump via a one-way bearing and is fixed to a rotating blade inside the manual pump.

[0018] 2. Ejector block one and ejector block two are provided. Ejector block one and ejector block two can be used to eject different positions of the pipe fitting product in sequence, preventing the pipe fitting product from being subjected to overall force and improving the demolding effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, such as Figures 1-6 The present invention provides the following technical solution to address the problem of insufficient ejection effect of the ejection device, which affects product quality: An ejection mechanism is disclosed, comprising a main body 1, with a mold 2 internally connected to the upper surface of the main body 1; a motor is installed inside the mold 2, with a large gear 201 fixed at the output end of the motor; a rotating rod 202 is rotatably connected to the side of the large gear 201 away from the motor via a one-way bearing; cams 203 are fixed to the surface and end of the rotating rod 202; an ejection mechanism for facilitating the ejection of pipe fittings is provided inside the mold 2; the ejection mechanism includes an ejector block 204, which slides through the cavity of the mold 2; a rubber wheel 205 is rotatably connected to the inner side of the cam 203; the rubber wheel 205 is in close contact with the ejector block 204; and the rotating rod 202 is positioned close to the ejector block 204. A transmission wheel 206 is fixed to the surface of the cam 203. A transmission belt 207 is connected to the surface of the transmission wheel 206. A transmission wheel 208 is connected to the inner side of the transmission belt 207 away from the transmission wheel 206. The transmission wheel 206, the transmission belt 207 and the transmission wheel 208 are connected for transmission. A gear rod 209 is fixed to the side of the transmission wheel 208. The gear rod 209 rotates inside the mold 2. A transmission gear 210 is meshed with the side of the gear rod 209. A top block 211 slides through the cavity of the mold 2 away from the top block 204. A toothed plate 212 is connected to the side of the top block 211 near the transmission gear 210. A sliding block 213 is fixed to the side of the toothed plate 212. The toothed plate 212 is meshed with the transmission gear 210. The sliding block 213 slides inside the top block 211.

[0032] When the ejection device is in use, the injection material forms a tubular product inside the cavity of mold 2. After the product cools and solidifies, the motor can drive the large gear 201 to rotate. When the large gear 201 rotates, it drives the rotating rod 202 to rotate via a one-way bearing. When the rotating rod 202 rotates, it drives the two cams 203 to rotate. When the cams 203 rotate, they drive the rubber wheel 205 to rotate. When the rubber wheel 205 rotates to the bottom of the top block 204, it can compress the product. After being compressed, the top block 204 can rise. When the top block 204 rises, it can compress the bottom of both ends of the product inside the cavity of mold 2. After the ends of the product are compressed, the whole product will become loose. At the same time, when the rotating rod 202 rotates, it drives the two transmission wheels 206 to rotate. The rotation of the transmission wheels 206 drives the transmission belt 207 to rotate. The rotation of the transmission belt 207 drives the transmission wheel 206 to rotate. 208 rotates inside mold 2. When transmission wheel 208 rotates, it can drive gear rod 209 to rotate. When gear rod 209 rotates, it can mesh and drive transmission gear 210 to rotate. When transmission gear 210 rotates, it can drive toothed plate 212 to mesh and move. When toothed plate 212 meshes and moves, it can drive sliding block 213 to move. When sliding block 213 moves, it can slide through top block 211. When sliding block 213 slides to the inner wall side of top block 211, it can be squeezed. By squeezing top block 211, the main part of the product inside the cavity can be ejected. After the product is ejected from the cavity of mold 2, the operator can perform demolding. The sliding of sliding block 213 inside top block 211 can prevent top block 204 from exerting force on both ends of the product when it ejects, so as not to directly cause the product to be subjected to force, thus improving the efficiency and quality of demolding.

[0033] Example 2, as follows Figure 1 , Figure 7 and Figure 8 The present invention provides the following technical solution: In order to solve the problem that the mold ejection device is inconvenient to clean the cavity and easily affects the product processing efficiency, based on the first embodiment, a blower mechanism is disclosed: a small gear 215 is meshed with the bottom of the large gear 201, and a blower mechanism for easy cleaning is also provided inside the mold 2. The blower mechanism includes a manual pump 214, which is installed inside the mold 2. The small gear 215 rotates through the manual pump 214 through a one-way bearing, and the small gear 215 is fixed on the rotating blade inside the manual pump 214. An external block 216 is fixed on the side of the main body 1 of the equipment. A handheld nozzle 217 is provided inside the external block 216. A connecting pipe 218 is connected between the handheld nozzle 217 and the manual pump 214. The connecting pipe 218 passes through the mold 2 and the main body 1 of the equipment.

[0034] After the product is ejected from the mold, there may be residue inside the cavity of mold 2. At this time, the reverse start motor can drive the large gear 201 to reverse. When the large gear 201 reverses, the one-way bearing cannot drive the rotating rod 202 to rotate, but the reverse of the large gear 201 can drive the small gear 215 to rotate. When the small gear 215 rotates, it can rotate inside the manual pump 214 through the one-way bearing. When the small gear 215 rotates, it can drive the rotating blades inside the manual pump 214 to rotate. When the blades inside the manual pump 214 rotate, airflow will be generated. The airflow can be delivered to the air outlet of the handheld nozzle 217 through the connecting pipe 218. At this time, the handle of the handheld nozzle 217 can be taken out from the outer block 216. The air outlet of the handheld nozzle 217 can be aligned with the cavity of mold 2 to clean the residue inside the cavity, thus improving the cleaning efficiency of the ejection device.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
