Description

Technical Field

[0001] This utility model relates to the field of material feeding technology for cable tie injection molding machines, and more particularly to the material feeding mechanism of cable tie injection molding machines. Background Technology

[0002] The working principle of an injection molding machine is similar to that of a syringe. It uses the thrust of a screw (or plunger) to inject pre-plasticized molten plastic (i.e., a viscous flow state) into a closed mold cavity. After solidification and shaping, the product is obtained. Injection molding is a cyclical process. Each cycle mainly includes: metered feeding—melting and plasticizing—pressure injection—mold filling and cooling—mold opening and part removal. After removing the plastic part, the mold is closed again for the next cycle.

[0003] Chinese Patent Publication No. CN220464565U discloses a utility model related to the field of plastic part unloading technology, specifically a plastic part unloading auxiliary device after injection molding. The device includes an injection molding machine with a discharge port at its bottom and a collection box below it. It also includes an unloading auxiliary component for assisting in the smooth unloading of plastic parts. The unloading auxiliary component is slidably disposed at the discharge port at the bottom of the injection molding machine. An alternating receiving component is detachably disposed within the collection box. The advantages of this utility model are: it allows for the orderly and smooth unloading of plastic parts after injection molding and discharge through the discharge port; it also allows for the alternating unloading of plastic parts into the alternating receiving component, making it convenient for workers to remove the unloaded plastic parts from the collection box and facilitating transportation within the production workshop, thus benefiting the unloading operation after injection molding.

[0004] For the existing cable tie injection molding machine's unloading mechanism, in actual use, after the cable tie is formed and the mold is opened, it is inconvenient for the cable tie to leave the mold, which makes unloading the cable tie time-consuming and troublesome. In addition, the unloaded cable ties are prone to collisions and damage, resulting in poor quality. Utility Model Content

[0005] The purpose of this invention is to provide a feeding mechanism for a cable tie injection molding machine, which solves the problems of inconvenient feeding and easy collision damage after feeding in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The feeding mechanism of the cable tie injection molding machine includes the injection molding machine and two molds. One mold has an insertion groove fixedly connected to its side. An extrusion mechanism is provided inside the insertion groove. A forming groove is opened on the surface of the other mold. The forming groove is connected to the insertion groove. An arc-shaped anti-leakage block is rotatably connected inside the forming groove. A sealing ring is fixedly connected inside the anti-leakage block. A collection box is provided at the bottom of the injection molding machine.

[0008] Preferably, the extrusion mechanism includes an extrusion rod that passes through the insertion groove, a fixing block is sleeved on the surface of the extrusion rod, the fixing block is fixedly connected to the side of the adjacent mold, an air pump is fixedly connected to the bottom of the fixing block, and the output shaft of the air pump is drivenly connected to the extrusion block.

[0009] Preferably, the surface of the extrusion rod is provided with an adjustment groove, and the top of the extrusion block passes through the interior of the adjustment groove.

[0010] Preferably, a support plate is slidably connected to the bottom of the collection box, a support rod is fixedly connected to the bottom of the support plate, and a base sleeve is fitted onto the surface of the support rod.

[0011] Preferably, an adjusting rod is provided on the surface of the base tube, and several lifting grooves are provided on the surface of the support rod, with the adjusting rod passing through the interior of adjacent lifting grooves.

[0012] Preferably, a shock-absorbing plate is fixedly connected to the top of the base tube, and a shock-absorbing ring is fixedly connected to one end of the support rod located inside the base tube.

[0013] This utility model has the following beneficial effects:

[0014] After the cable ties are formed by the injection molding machine, the two molds can be separated by the injection molding machine. Then, the air pump drives the extrusion block to squeeze the extrusion rod, causing the extrusion rod to move and squeeze the cable ties out of the forming groove through the anti-leakage block. This makes it easy to unload the cable ties after forming. The cable ties enter the collection box, and the height of the collection box is adjusted by the support rod and the base cylinder to prevent the cable ties from falling too far and being damaged. This ensures that the cable ties are collected safely. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5The feeding mechanism of the cable tie injection molding machine includes an injection molding machine 1 and two molds 2. The injection molding machine 1 is existing technology. The raw material is injected into the space between the two molds 2 through the injection molding machine 1, and then cooled to form the cable tie. Then, the two molds 2 are separated by the injection molding machine 1, thereby extruding the formed cable tie. An insertion groove 3 is fixedly connected to the side of one of the molds 2. An extrusion mechanism 4 is provided inside the insertion groove 3. After the two molds 2 are separated, the extrusion mechanism 4 in the insertion groove 3 can easily extrude the formed cable tie, allowing the cable tie to enter the space below. The material is collected in the collection box 8. One of the molds 2 has a forming groove 5 on its surface, which is connected to the insertion groove 3. The two molds 2 are assembled into a forming mold 2. The raw material is injected into the forming groove 5 inside the two molds 2, and then cooled. After cooling, the two molds 2 are separated. The forming groove 5 is the groove for injecting the raw material, and the other mold 2 serves to seal the forming groove 5. The forming groove 5 is rotatably connected to an arc-shaped anti-leakage block 6, which is located at one end of the insertion groove 3. During the cable tie forming process, the anti-leakage block 6 rotates to close the insertion groove 3. During material injection, the material also compresses the anti-leak block 6, allowing it to better seal the insertion groove 3 and preventing leakage. After molding, the extrusion mechanism 4 further compresses the anti-leak block 6, causing it to rotate and compress the cable tie. This allows the cable tie to be easily extruded from the molding groove 5, facilitating unloading. After unloading, the weight of the anti-leak block 6 causes it to rotate back into the insertion groove 3, continuing to block it. The internal fixing connection of the anti-leak block 6... A sealing ring 7 is provided, which can improve the sealing between the anti-leakage block 6 and the insertion groove 3, thereby better preventing raw materials from entering the insertion groove 3 and affecting the use of the extrusion mechanism 4. A collection box 8 is provided at the bottom of the injection molding machine 1. The collection box 8 can conveniently collect the extruded cable ties and then move the cable ties to the subsequent processing steps. The collection box 8 is located at the bottom of the injection molding machine 1. When the two molds 2 are separated, the collection box 8 is located in the space between the two molds 2, so that once the cable ties leave the forming groove 5, they can enter the collection box 8 by gravity for collection.

[0024] Furthermore, the extrusion mechanism 4 includes an extrusion rod 401 passing through the insertion groove 3. A fixing block 402 is sleeved on the surface of the extrusion rod 401. The fixing block 402 is fixedly connected to the side of the adjacent mold 2. An air pump 403 is fixedly connected to the bottom of the fixing block 402. The output shaft of the air pump 403 is drivenly connected to the extrusion block 404. When the two molds 2 are separated, the air pump 403 can be started. After the air pump 403 is started, it drives the extrusion block 404 to move, thereby enabling the extrusion block 404 to be driven by the fixing block 402. The extrusion rod 401 moves, causing one end of the extrusion rod 401 to apply force to the leak-proof block 6, causing the leak-proof block 6 to rotate and extrude the cable tie. After the extrusion is completed, the air pump 403 can be reset. The air pump 403 drives the extrusion rod 401 back to its original position through the fixing block 402. A pull wire can be connected between the leak-proof block 6 and the extrusion rod 401. After the extrusion rod 401 is reset, it can drive the leak-proof block 6 to move, causing the leak-proof block 6 to rotate and close the insertion slot 3, thus facilitating the extrusion of the cable tie.

[0025] Furthermore, an adjustment groove 405 is formed on the surface of the extrusion rod 401. The top of the extrusion block 404 passes through the interior of the adjustment groove 405. The extrusion block 404 is an inclined block, and the adjustment groove 405 is an inclined groove. When the extrusion block 404 enters the interior of the adjustment groove 405, it will be pressed by the inclined surface of the extrusion block 404 against the inclined surface of the adjustment groove 405, thereby driving the extrusion rod 401 to move towards the forming groove 5. After the extrusion is completed, the air pump 403 drives the extrusion block 404 to reset. During the reset process of the extrusion block 404, the extrusion block 404... 4. The other inclined surface of the adjustment groove 405 presses against the other inclined surface, causing the extrusion rod 401 to move away from the forming groove 5, thereby resetting the extrusion rod 401. When the extrusion rod 401 needs to move to extrude the cable tie, it only needs to move a short distance. The extrusion rod 401 does not need to move a long distance. The extrusion block 404 moves in and out of the adjustment groove 405 to control the extrusion rod 401 within a certain limit, preventing the extrusion rod 401 from moving too violently and causing damage to the mold 2. The extrusion of the cable tie is carried out under safe cleaning conditions.

[0026] Furthermore, a support plate 9 is slidably connected to the bottom of the collection box 8, and a support rod 10 is fixedly connected to the bottom of the support plate 9. A base cylinder 11 is sleeved on the surface of the support rod 10. When collecting cable ties through the collection box 8, the support rod 10 and the base cylinder 11 are used to support the collection box 8 on the support plate 9, so that the distance between the collection box 8 and the mold 2 is closer, preventing the cable ties from falling a long distance into the collection box 8 and causing damage.

[0027] Furthermore, an adjusting rod 12 is provided on the surface of the base cylinder 11, and several lifting grooves 13 are provided on the surface of the support rod 10. The adjusting rod 12 is inserted into the interior of the adjacent lifting grooves 13. When it is necessary to adjust the height of the collection box 8 so that the collection box 8 can be close to the mold 2 for convenient collection of cable ties, the support rod 10 can move up and down inside the base cylinder 11. During the movement, the height of the support rod 10 can be controlled by inserting the adjusting rod 12 into the interior of the lifting groove 13, so that the height of the collection box 8 can be changed conveniently, preventing collision damage when the cable ties fall.

[0028] Furthermore, a shock-absorbing plate 14 is fixedly connected to the top of the base cylinder 11, and a shock-absorbing ring 15 is fixedly connected to one end of the support rod 10 located inside the base cylinder 11. Both the shock-absorbing plate 14 and the shock-absorbing ring 15 can ensure that the support rod 10 will not vibrate during use, thus ensuring the stability of the bearing plate 9 and the collection box 8.

[0029] In summary:

[0030] When producing cable ties, the injection molding machine 1 and mold 2 are used to form the cable ties. The cable ties are formed in the forming groove 5 on the surface of one of the molds 2. After the raw material is injected, it is cooled and formed. After cooling, the injection molding machine 1 separates the two molds 2 and then the formed cable ties are exposed. Then, the air pump 403 is started. The air pump 403 can drive the extrusion block 404 to move into the fixed block 402, so that the extrusion block 404 is inserted into the adjustment groove 405 on the surface of the extrusion rod 401. By extruding the adjustment groove 405, the extrusion rod 401 moves into the forming groove 5 in the insertion groove 3, so that one end of the extrusion rod 401 can extrude the leak-proof block 6, causing the leak-proof block 6 to rotate and extrude the cable ties out of the forming groove 5 and into the collection box 8 for collection. After the cable ties are finished being produced, the air pump 403 is reset, so that the extrusion block 404 is reset and the extrusion rod 401 is reset. During this process, the extrusion block 404 is extruded into the mold 5 and then into the collection box 8 for collection. Rod 401 can drive the anti-leakage block 6 to rotate and seal the insertion slot 3 via a pull wire. The anti-leakage block 6 increases the sealing of the insertion slot 3 through the sealing ring 7, so that the raw material will not enter the insertion slot 3 during feeding. When the cable ties are collected by the collection box 8, the support rod 10 can be raised and lowered inside the base cylinder 11, so that the height of the collection box 8 on the bearing plate 9 can be easily changed. Then, the height of the support rod 10 is fixed by inserting the adjustment rod 12 into the adjacent lifting slot 13. The support rod 10 and the base cylinder 11 are stabilized by the shock-absorbing plate 14 and the shock-absorbing ring 15, so that there will be no shaking or vibration, and the stability of the cable tie feeding is guaranteed. With the above structure, after the cable tie is formed, the extrusion rod 401 can easily push the cable tie out of the forming slot 5 and into the collection box 8. While making it easy and quick to demold, the safety of the cable tie after entering the collection box 8 is guaranteed, and the cable tie is prevented from being easily damaged.
