Description

Technical Field

[0001] The utility model belongs to the field of injection molding product production equipment, and particularly relates to an edge grinding device for injection molding products. Background Art

[0002] During the production process of injection molding products, flash is inevitably generated at the mold clamping edge. For relatively large flash, the current effective solution is to reduce the size of the flash by adjusting the mold. However, even after adjustment, there will still be fine flash on the produced injection molding products. Since the production mold can no longer solve the generation of fine flash, but the flash existing on the product will actually affect the product experience, especially the adverse effects such as being cut by the flash or having an obstructive feeling when holding. Therefore, for fine flash, it is mostly processed manually by grinding the flash. However, the manual processing method will cause workers to spend a lot of time on material handling, grinding, and discharging, and also need to clean the grinding site after completing the work. The actual processing process is time-consuming and laborious. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides an edge grinding device for injection molding products. The material is conveyed onto the adsorption box through the feeding conveyor belt. Since an operation cover is sleeved on the adsorption box, the operation holes on the operation cover can allow workers to reach in and take the material to grind the flash on the grinding column of the adsorption box. The burrs after grinding can enter the adsorption box for collection, and the material after grinding is directly placed on the discharging conveyor belt to send out the material. The edge grinding operation is concentrated at the upper end of the adsorption box. Besides being convenient for feeding and discharging, it can also collect the burrs after grinding in a timely manner.

[0004] To achieve the above object, the technical solution adopted by the utility model is:

[0005] An edge grinding device for injection molding products, comprising a bracket, an adsorption assembly, a conveying assembly, a grinding assembly, and an operation cover. The adsorption assembly is connected above the bracket. The adsorption assembly includes an adsorption box. An adsorption cavity is provided inside the adsorption box. A feeding groove and a discharging groove are provided on the upper end surface of the adsorption box. A plurality of adsorption holes communicating with the adsorption cavity are provided on the upper end surface of the adsorption box. The conveying assembly includes a feeding conveyor belt and a discharging conveyor belt. The upper end surfaces of the feeding conveyor belt and the discharging conveyor belt are respectively embedded in the feeding groove and the discharging groove. The grinding assembly includes a motor and a grinding column. The motor is arranged inside the adsorption cavity. The output end of the motor penetrates through the adsorption box and is connected to the grinding column. An operation cavity is provided inside the operation cover. Feeding holes, discharging holes, and two groups of operation holes communicating with the operation cavity are provided on the operation cover. The lower end opening of the operation cover is sleeved on the upper end surface of the adsorption box. The feeding holes and the discharging holes are both arranged at the lower edge of the operation cover, and the feeding holes and the discharging holes respectively correspond to the feeding groove and the discharging groove.

[0006] The adsorption assembly also includes a baffle, a blowing plate, a fan seat, a fan and an outlet hole. The baffle is detachably connected to the upper end surface of the adsorption box, and the baffle encloses the upper end surface of the feed conveyor belt in the feed trough; the blowing plate is arranged on the upper end surface of the adsorption box, and a plurality of blowing heads are provided on the blowing plate, and the blowing heads point to the upper end surface of the discharge conveyor belt, and a plurality of the blowing heads are connected to the air pump; the fan seat is arranged on the front end side surface of the adsorption box, and the fan is detachably connected to the fan seat, and the outlet hole is arranged on the rear end side surface of the adsorption box and points to the fan seat, and the lower end surface of the outlet hole overlaps with the bottom surface of the adsorption chamber.

[0007] In the edge grinding device for injection molded products adopting this structure, the bracket provides the necessary supporting force for the adsorption box, and the output end of the motor provided in the adsorption chamber extends out of the adsorption box and is connected to the grinding column. When the motor is started, the grinding column will also rotate. At this time, the worker takes the material to the upper end of the adsorption box, and manually presses the part to be polished against the high-speed rotating grinding column, so that the fine flash on the material can be polished off, and the burrs dropped by grinding fall on the upper end surface of the adsorption box. In order to collect the dropped burrs, an adsorption chamber is provided in the adsorption box, which is used to drop the burrs on the upper end of the adsorption box into it after grinding. However, the collection effect of simply relying on the burrs falling by themselves is still not good. Therefore, a number of adsorption holes connected to the adsorption chamber are provided on the upper end surface of the adsorption box, so that the burrs can be sucked from the upper end of the adsorption box into the adsorption chamber. In order to provide suction force, a plurality of adsorption holes connected to the adsorption chamber are provided on the upper end surface of the adsorption box. A fan seat is provided on the front side surface of the adsorption box, and a fan is installed on the fan seat. At the same time, an outlet hole is provided on the rear end side surface of the adsorption box. Therefore, when the fan is started, the external air is sucked into the adsorption chamber by the fan. Since the outlet hole points to the fan seat, the sucked air will be blown out directly from the outlet hole, so that the adsorption holes on the upper end surface of the adsorption box are subjected to the effect of negative pressure, generating a downward suction force. Therefore, when the fan is turned on, the adsorption holes will generate a continuous downward adsorption force to adsorb the burrs on the upper end of the adsorption box into the adsorption chamber, and finally bring them out from the outlet hole. In order to avoid the accumulation of burrs in the adsorption chamber, the lower end surface of the outlet hole is overlapped with the bottom surface of the adsorption chamber. Therefore, when the burrs fall to the bottom of the adsorption chamber, they can be completely discharged along the outlet hole. A collection bag can be installed on the outside of the outlet hole so that the burrs can be collected and packaged for waste transportation.

[0008] In order to achieve a streamlined production process, it is necessary to automatically introduce materials into the adsorption chamber and automatically transport the processed materials out. Therefore, a feeding conveyor belt and a discharging conveyor belt are set up. To make the upper surface of the conveyor belt fit the top surface of the adsorption box, a feeding groove and a discharging groove are set on the top surface of the adsorption box. The upper surfaces of the feeding conveyor belt and the discharging conveyor belt are respectively embedded in the feeding groove and the discharging groove, so that the upper surfaces of the feeding conveyor belt and the discharging conveyor belt are flush with the top surface of the adsorption box, making the process of transporting materials smoother. Therefore, under the drive of the feeding conveyor belt, the materials are automatically introduced onto the adsorption box. After being picked up manually, the materials are manually operated to grind off the flash. The processed materials are then manually placed on the discharging conveyor belt, and the discharging conveyor belt transports the processed materials to the next process.

[0009] Since the materials transported to the upper end of the adsorption box may be taken out of the upper end of the adsorption box before they can be picked up in time, to avoid this situation, a baffle is added to the upper end of the adsorption box. The baffle encloses the upper end of the feeding conveyor belt in the feeding groove, so that the materials driven on the feeding conveyor belt will be blocked by the baffle near the edge of the adsorption box after being transported on the adsorption box for a certain distance, preventing the materials from being continuously transported and falling out of the adsorption box. The baffle can be adjusted at the corners so that when the materials hit the baffle, they can change direction and be temporarily pushed onto the adsorption box for temporary storage. During the process of manually grinding the flash of the materials, the burrs will fly randomly. In addition to being adsorbed into the adsorption chamber by the adsorption holes, the burrs may also fall on the feeding conveyor belt and the discharging conveyor belt. The burrs falling on the feeding conveyor belt will not have any impact and will also shift towards the adsorption holes under the blocking of the baffle and will ultimately be adsorbed into the adsorption holes. However, the burrs falling on the discharging conveyor belt may be directly carried into the next process, resulting in the accumulation of burrs in the next process and requiring time and effort to clean up. Therefore, a blowing plate is also provided on the adsorption box. The blowing plate is set at the front end position of the discharging conveyor belt near the exit of the adsorption box. The blowing heads on the blowing plate point to the upper surface of the discharging conveyor belt. The blowing heads are connected to an air pump. When the air pump supplies air, the blowing heads blow away the burrs on the discharging conveyor belt. Since the burrs are light and the materials are heavy, an appropriate wind force can only blow away the burrs and cannot blow the materials, thus avoiding the burrs being carried into the next process and the need for subsequent cleaning.

[0010] During the grinding process, the burrs will fly randomly. If not restricted, the burrs after grinding will still scatter around the device. Therefore, an operation cover is sleeved on the upper surface of the adsorption box. Two operation holes on the operation cover allow the worker's hands to reach into the operation chamber to grind the flash. The feeding hole and the discharging hole at the lower edge of the operation cover correspond to the feeding groove and the discharging groove respectively. Therefore, the space on the upper surface of the adsorption box is enclosed, and the burrs cannot fly out of the operation cover during the process of grinding the burrs, which is more convenient for the collection of burrs and manual operation.

[0011] Furthermore, a grinding head is provided on the upper end surface of the grinding column.

[0012] Compared with the prior art, the advantages of the present utility model are as follows: By providing the grinding column on the adsorption box, it is convenient for workers to abut the burrs on the material against the grinding column for flash trimming. The trimmed burrs are blocked by the operation cover in the operation cavity, and the burrs fall into the adsorption cavity under the adsorption force of the adsorption holes, and are blown out of the export hole by the blowing of the fan. A collection bag can be sleeved outside the export hole for collection and packing, which is convenient for waste transportation. Moreover, the material can be automatically conveyed to the upper end of the adsorption box through the feeding conveyor belt for workers to take and perform flash trimming, and the trimmed material can be taken out through the discharging conveyor belt, thus realizing a streamlined operation, which is time-saving and labor-saving throughout the process.

Feed holes 52, discharge holes 53, and two groups of operation holes 54 communicating with the operation cavity 51 are provided on the operation cover 5. The lower opening of the operation cover 5 is sleeved on the upper end surface of the adsorption box 21. The feed holes 52 and the discharge holes 53 are both provided at the lower edge of the operation cover 5.

The blowing plate 23 is arranged on the upper end surface of the adsorption box 21. A number of blowing heads 231 are provided on the blowing plate 23. The blowing heads 231 point to the upper end surface of the outlet conveyor belt 32. A number of the blowing heads 231 are connected to an air pump. The fan 25 seat 24 is arranged on the front side surface of the adsorption box 21. The fan 25 is detachably connected to the fan 25 seat 24.

[0024] Further, a grinding head 43 is provided on the upper end surface of the grinding column 42.

[0025] Description of the working mode of the present utility model:

[0026] For the edge grinding device of an injection molded product adopting this structure, the bracket 1 provides necessary supporting force for the adsorption box 21. The output end of the motor 41 arranged in the adsorption cavity 211 extends out of the adsorption box 21 and is connected to the grinding column 42. When the motor 41 is started, the grinding column 42 will also rotate accordingly. At this time, the worker takes the material to the upper end of the adsorption box 21, and manually presses the part to be ground against the high-speed rotating grinding column 42, so that the fine flash on the material can be ground off. In case of finer burrs, the grinding head 43 on the upper end face of the grinding column 42 can perform more delicate grinding during rotation. The burrs ground off will fall on the upper end face of the adsorption box 21. In order to collect the fallen burrs, an adsorption cavity 211 is arranged in the adsorption box 21 for the burrs on the upper end of the adsorption box 21 to fall into after grinding. However, the collection effect relying solely on the self-falling of the burrs is still not good. Therefore, a number of adsorption holes 214 communicating with the adsorption cavity 211 are arranged on the upper end face of the adsorption box 21 for sucking the burrs from the upper end of the adsorption box 21 into the adsorption cavity 211. In order to provide suction force, a fan 25 seat 24 is arranged on the front side surface of the adsorption box 21, and a fan 25 is installed on the fan 25 seat 24. At the same time, an outlet hole 26 is arranged on the rear side surface of the adsorption box 21. Therefore, when the fan 25 is started, the external air is sucked into the adsorption cavity 211 by the fan 25. Since the outlet hole 26 points to the fan 25 seat 24, the sucked air will directly blow out from the outlet hole 26, making the adsorption holes 214 on the upper end face of the adsorption box 21 under the action of negative pressure, generating a downward suction force. Therefore, when the fan 25 is turned on, the adsorption holes 214 will generate a continuous downward adsorption force to adsorb the burrs on the upper end of the adsorption box 21 into the adsorption cavity 211 and finally take them out from the outlet hole 26. In order to prevent the burrs from accumulating in the adsorption cavity 211, the lower end face of the outlet hole 26 overlaps with the bottom surface of the adsorption cavity 211. Therefore, when the burrs fall to the bottom of the adsorption cavity 211, they can be completely exported along the outlet hole 26. A collection bag can be sleeved outside the outlet hole 26 so that the burrs can be collected and packed for waste transportation.

[0027] In order to achieve a streamlined production process, materials need to be automatically introduced into the adsorption chamber 211, and the completed materials need to be automatically transported out. Therefore, a feeding conveyor belt 31 and a discharging conveyor belt 32 are provided. To ensure that the upper surfaces of the conveyor belts are flush with the top surface of the adsorption box 21, a feeding groove 212 and a discharging groove 213 are provided on the top surface of the adsorption box 21. The upper surfaces of the feeding conveyor belt 31 and the discharging conveyor belt 32 are respectively inserted into the feeding groove 212 and the discharging groove 213, making the upper surfaces of the feeding conveyor belt 31 and the discharging conveyor belt 32 flush with the top surface of the adsorption box 21, which makes the process of transporting materials smoother. Therefore, under the drive of the feeding conveyor belt 31, materials are automatically transferred onto the adsorption box 21, and then picked up by workers for manual grinding and deburring. After grinding, the materials are manually placed on the discharging conveyor belt 32, and the discharging conveyor belt 32 transports the ground materials to the next process.

[0028] Since the materials transferred to the upper end of the adsorption box 21 may be carried out of the upper end of the adsorption box 21 before they can be picked up, in order to avoid this situation, a baffle 22 is added to the upper end of the adsorption box 21. The baffle 22 encloses the upper end of the feeding conveyor belt 31 within the feeding groove 212, so that the materials driven on the feeding conveyor belt 31 will be blocked by the baffle 22 near the edge of the adsorption box 21 after being transported on the adsorption box 21 for a certain distance, preventing the materials from being continuously transported and falling out of the adsorption box 21. The baffle 22 can be adjusted at the corners so that when the materials hit the baffle 22, they can change direction and be temporarily pushed onto the adsorption box 21 for temporary storage. During the process of manual grinding and deburring of the materials, the burrs will fly randomly. In addition to being adsorbed into the adsorption chamber 211 by the adsorption holes 214, the burrs may also fall on the feeding conveyor belt 31 and the discharging conveyor belt 32. The burrs falling on the feeding conveyor belt 31 will not have any impact and will also shift towards the adsorption holes 214 under the blocking of the baffle 22 and will eventually be adsorbed into the adsorption holes 214. However, the burrs falling on the discharging conveyor belt 32 may be directly carried into the next process, resulting in the accumulation of burrs in the next process and requiring time-consuming and laborious cleaning. Therefore, a blowing plate 23 is also provided on the adsorption box 21. The blowing plate 23 is arranged at the front position of the discharging conveyor belt 32 near the exit of the adsorption box 21. The blowing heads 231 on the blowing plate 23 point to the upper surface of the discharging conveyor belt 32. The blowing heads 231 are connected to an air pump, and under the supply of air by the air pump, the blowing heads 231 blow the burrs on the discharging conveyor belt 32 away. Since the burrs are light and the materials are heavy, an appropriate wind force can only blow away the burrs and cannot blow the materials, so that the burrs can be prevented from being carried into the next process and the need for subsequent cleaning can be avoided.

[0029] During the deburring process, the burrs will fly around randomly. If not restricted, the deburred burrs will still scatter around the device. Therefore, an operation cover 5 is sleeved on the upper end surface of the adsorption box 21. The operation cover 5 is made of transparent material, which facilitates internal observation from the outside. Two operation holes 54 on the operation cover 5 allow workers to insert their hands into the operation cavity 51 for flash deburring. The feed hole 52 and the discharge hole 53 at the lower edge of the operation cover 5 correspond to the feed chute 212 and the discharge chute 213 respectively. Thus, the space on the upper end surface of the adsorption box 21 is enclosed, and the burrs cannot fly out of the operation cover 5 during the deburring process, making it more convenient for burr collection and manual operation.

[0030] The beneficial effects of the present utility model are as follows: Through the arrangement of the deburring posts 42 on the adsorption box 21, it is convenient for workers to abut the burrs on the material against the deburring posts 42 for flash deburring. The deburred burrs are blocked in the operation cavity 51 by the operation cover 5, and the burrs fall into the adsorption cavity 211 under the adsorption force of the adsorption holes 214, and are blown out of the outlet hole 26 by the blowing of the fan 25. A collection bag can be sleeved outside the outlet hole 26 for collection and packing, which is convenient for waste transportation. Moreover, the material can be automatically brought to the upper end of the adsorption box 21 through the feed conveyor belt for workers to take and perform flash deburring, and the material after deburring can be taken out through the discharge conveyor belt 32, thus realizing a streamlined operation, which saves time and effort throughout the process.

[0031] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
