Background

Most plastic products are often produced by injection molding. The injection molding method has the advantages of both injection and molding, and has the characteristics of quick molding, high production efficiency and high precision of finished products. During injection molding, a gate is inevitably present. The water gap is a joint part between the frame and the part formed during casting the model, and is an inlet and an outlet for the flow of the heated liquid material, so that the liquid material is prevented from flowing back in the injection molding process.

When the injection molding is completed, a manual operation method is often adopted to remove the water gap in the process of taking out the product. The position of the additional nozzle is different due to different injection molded products. The resulting nozzle shapes are large for some common tubular, cylindrical types of products.

As shown in the drawings, an automatic injection molded part removing nozzle device 1 according to a preferred embodiment of the present invention is illustrated. The automatic water gap removing device 1 for injection molding is used for removing a water gap 981 generated when an injection molding 980 is injection molded. The nozzle 981 is integrally connected to the injection molded part 980. The injection molded part 980 cannot be a qualified product due to the presence of the nozzle 981. Therefore, the water gap 981 is separated from the injection-molded part 980 through the automatic water gap removing device 1 for the injection-molded part, and the manual operation is replaced by automatic equipment.

The automatic injection molding part removing water gap device 1 comprises a removing structure 910, a limiting structure 920 and a positioning structure 930. The removal structure 910 is connected to the position limiting structure 920, and the position limiting structure 920 is movably connected to the positioning structure 930. In this embodiment, the removing structure 910 is movably connected to the limiting structure 920. Specifically, the limiting structure 920 is sleeved at the bottom of the removing structure 910. In other words, the removal structure 910 is coaxially connected to the limiting structure 920, and the removal structure 910 is located at the upper portion of the limiting structure 920. The removal structure 910 may remove the nozzle 981 located in the injection molded part 980. The locating structure 930 provides for corresponding positioning of the removal structure 910 and the gate 981 to define the location of the injection molded part 980 and the removal structure 910. The limiting structure 920 is used for fixing the injection-molded part 980 so as to ensure that the positions of the water gap 981 and the removing structure 910 are further limited when the removing structure 910 works. In other words, the removal structure 910 defines the position of the nozzle 981 by the positioning structure 930 and the limiting structure 920, so that the cutting of the nozzle 981 has higher precision.

The removal structure 910 includes a driving unit 911 and an execution unit 912, wherein the driving unit 911 is electrically connected to the execution unit 912. Further, the driving unit 911 is located at an upper portion of the execution unit 912 to control the execution unit 912 to move up and down. Specifically, the drive unit 911 drives the execution unit 912 to operate, and the execution unit 912 removes the water port 981 of the injection molding 980.

In one embodiment, the actuating unit 912 is specifically a pair of scissors 912B, and the scissors 912B are adapted to cut the strip-shaped nozzle located at the tubular end surface and the connecting nozzle located between the parts separated from each other. The scissors 912B are controlled by the driving unit 911 to perform a multi-cutting process. In another embodiment of the present invention, the execution unit 912 is specifically a milling cutter 912A, and the milling cutter 912A is installed at the bottom of the driving unit 911. To facilitate the operability of the milling cutter 912A during operation, the milling cutter 912A is located at the bottom center of the driving unit 911. The milling cutter 912A is preferably adapted for use with the nozzle 981 located in the inner tubular wall and the nozzle 981 located in the groove. The drive unit 911 controls the milling tool 912A to realize the nozzle 981 inside the injection molded part 980.

The scissors 912B are applicable to a wider position of the nozzle 981 than the milling cutter 912A, but the milling cutter 912A has higher processing accuracy of the nozzle 981 than the scissors 912B.

It is worth mentioning that the automatic injection molded part removal nozzle assembly 1 further comprises a sensing assembly 960. The sensing assembly 960 includes a first sensing member 961 and a second sensing member 962. The first sensing member 961 is located at the positioning structure 930 and the second sensing member 962 is located at the drive unit 911. The first sensing member 961 is electrically connected to the positioning structure 930 and the second sensing member 962 is electrically connected to the driving unit 911. In particular, said first sensing member 961 is adapted to the three-dimensional positioning of said injection-molded part 980, and said second sensing member 962 is adapted to said nozzle 981 in a detailed position of said injection-molded part 980. That is, the first sensing member 961 is used for coarse positioning, and the second sensing member 962 is used for fine positioning. The sensing component 960 receives signals of the relative position relationship between the execution unit 912 and the injection molded part 980, so as to ensure that the execution unit 912 does not damage the inner wall of the injection molded part 980 when the execution unit 912 is in operation. Specifically, the execution unit 912 determines the cutting range through the sensing assembly 960, and completes the cutting of the nozzle 981 without damaging the rest surface of the injection molded part 980.

The limiting structure 920 is used for fixing the injection-molded part 980 and providing an installation platform for the removing structure 910. The limiting structure 920 comprises a fixed platform 924 and a movable platform 923, wherein the fixed platform 924 is located on the upper portion of the movable platform 923. In other words, the movable table 923 is movably located under the fixed table 924. Specifically, the limiting structure 920 includes a buffering unit 921. The buffering unit 921 is located between the movable stage 923 and the fixed stage 924. Further, the buffering unit 921 is located at the top of the movable table 923, and the buffering unit 921 is located at the bottom of the fixed table 924. That is, the movable stage 923 is connected to the fixed stage 924 through the buffering unit 921. In other words, the buffering unit 921 is movably installed between the movable table 923 and the fixed table 924. In particular, there is a gap between the movable table 923 and the fixed table 924. That is, the movable stage 923 and the fixed stage 924 are separated from each other, and a predetermined distance is provided between the top surface of the movable stage 923 and the bottom surface of the fixed stage 924. When the limiting structure 920 works, the buffering unit 921 can buffer the pressure between the limiting structure 920 and the injection molded part 980. Specifically, when the limit structure 920 descends to the top surface height of the injection molding 980, the movable table 923 located at the bottom contacts the injection molding 980 first, the movable table 923 supports against the injection molding 980, and the buffer unit 921 releases the contact pressure to prevent the deformation of the outer surface of the injection molding 980 due to the pressure.

The limiting structure 920 has a working channel 926, and the working channel 926 penetrates through the movable table 923 and the fixed table 924. That is, the working channel 926 communicates between the top surface of the fixed stage 924 and the bottom surface of the movable stage 923. Further, the working channel 926 is adapted to receive the removal structure 910. In other words, the execution unit 912 is located inside the working channel 926. When the removal structure 910 is in operation, the removal structure 910 is movably positioned within the working channel 926 to effect removal of the nozzle 981.

The limiting structure 920 further comprises a limiting groove 925, and the limiting groove 925 is located at the bottom of the movable table 923. Specifically, the limiting groove 925 is disposed on the bottom end surface of the movable table 923 with the center of the working channel 926 as a circle center. In other words, the retainer groove 925 and the working channel 926 are coaxially arranged. The diameter of the retaining groove 925 is optionally larger than the diameter of the working channel 926. When the retaining structure 920 is lowered to the height of the upper top surface of the injection molded part 980, the upper top surface of the injection molded part 980 is retained by the retaining grooves 925. That is, when the injection molded part is automatically removed from the operating state of the nozzle device 1, the top of the injection molded part 980 abuts against the surface of the stopper groove 925. In other words, the limiting groove 925 limits the positional offset of the injection molded part 980.

It is worth mentioning that the buffering unit 921 further includes a plurality of springs 9211 and a plurality of connection rods 9212. The spring 9211 with the connecting rod 9212 is located between the fixed station 924 and the movable station 923 with connecting the fixed station 924 with the movable station 923. In other words, one end of the spring 9211 and one end of the connecting rod 9212 are connected to the fixed platform 924, and the other end thereof is connected to the movable platform 923. Specifically, the spring 9211 with the connecting rod 9212 crisscross interval arrange in activity platform 923 with the clearance between the fixed station 924. Spring 9211 upper end connect in the lower surface of fixed station 924, the lower extreme connect in the upper surface of activity platform 923. Limiting structure 920 still has a plurality of recesses 922, recess 922 be set up respectively in the lower surface of fixed station 924 with the upper surface of activity platform 923. The groove 922 is adapted to receive the connecting rod 9212. That is, the connection rod 9212 is adapted to be movably engaged with the groove 922. The connecting rod 9212 connects the fixed table 924 and the movable table 923 relatively fixedly. The length of connecting rod 9212 is greater than the fixed station 924 with the clearance distance between the movable table 923. Be located of fixed station 924 the terminal surface of recess 922 to being located the activity platform 923 the distance between the terminal surface of recess 922 is greater than the length of connecting rod 9212.

Therefore, when the limiting structure 920 is lowered to the height of the top surface of the injection molded part 980, the top surface of the injection molded part 980 firstly contacts the end surface of the limiting groove 925, and then the movable table 923 abuts against the injection molded part 980 and stops lowering. The fixed stage 924 continues to descend due to the gap between the fixed stage 924 and the movable stage 923. Limited by the blocking of the buffer unit 921, the fixed table 924 stops descending at the position where it does not contact the movable table 923, the whole descending process is affected by the buffer unit 921 to weaken the pressure of the upper top surface of the movable table 923 and the injection molding 980, the pressure of the descending of the movable table 923 is prevented from being too large, the upper top surface of the injection molding 980 acts and deforms, and the integrity of the injection molding 980 is maintained. So that the injection-molded part 980 is limited by the limiting structure 920 and the water gap 981 of the injection-molded part 980 can be removed in the subsequent operation process of the removing structure 910.

The positioning structure 930 provides a mounting platform for the removal structure 910 and the retention structure 920. That is, the removing structure 910 and the limiting structure 920 are mounted to the positioning structure 930. The positioning structure 930 is used as a driving component of the automatic injection molding part removing nozzle device 1, and before the operation of removing the nozzle 981 from the injection molding part 980 is carried out, the positioning structure 930 needs to perform preliminary positioning on the injection molding part 980 so as to further define the position of the injection molding part 980 and perform the next removing operation. That is, the positioning structure 930 guides the removing structure 910 and the stopper structure 920 to a predetermined position for removing the nozzle 981.

Further, the positioning structure 930 includes a sliding rail 931, a connecting member 932 and a lifting member 933. The connector 932 is slidably connected to the slide rail 931, and the lifting member 933 is connected to the connector 932. In other words, the connector 932 is connected to the slide rail 931 at one end, and connected to the lifting member 933 at the other end. In particular, the connector 932 is telescopically arranged to the sliding rail 931. In this embodiment, the slide rail 931 is disposed in the X-axis direction, the connecting element 932 is disposed in the Z-axis direction, and the lifting element 933 is disposed in the Y-axis direction. In other words, the slide rail 931, the connector 932 and the lift 933 are perpendicular to each other.

It is worth mentioning that the first sensing member 961 is electrically connected to the positioning structure 930. That is, the first sensing member 961 is also disposed on the positioning structure 930. The slide rail 931 is arranged on the upper part of the injection molded part 980 to be processed to position the removal structure 910 in the X-axis direction. When the removing structure 910 is slidably positioned on the same Z axis as the injection molded part 980 through the slide rail 931, the first sensing member 961 disposed on the slide rail 931 receives a signal of successful positioning, and the removing structure 910 stops sliding on the slide rail 931. By this, the positioning of the slide rail 931 is completed. When the removal structure 910 is telescopically positioned on the same Y-axis as the injection molded part 980 by the connecting part 932, the first sensing member 961 arranged on the connecting part 932 receives a signal that the positioning is successful, and the removal structure 910 is still right above the injection molded part 980. At this point, the injection molded part 980 and the removal structure 910 are coaxially arranged. By this, the positioning of the connecting member 932 is completed. When the removing structure 910 is lifted and positioned to be on the same axis with the injection-molded part 980 through the lifting piece 933, a warning distance which can be sensed by the first sensing member 961 is preset from the top surface of the injection-molded part 980 in the process that the first sensing member 961 arranged with the lifting piece 933 is lifted and lowered by the lifting piece 933. That is, when the lifting member 933 drives the removing structure 910 to descend to a predetermined distance from the top surface of the injection molded part 980, the first sensing member 961 receives a signal to suspend the lifting member 933 from descending continuously. In other words, at this time, the lift 933 brings the removal structure 910 close to the injection molded part 980. At this point, the positioning of the lift 933 is completed. At this point, the process of positioning the structure 930 is complete, i.e., the coarse positioning of the injection molded part 980 is complete. At this time, the automatic injection molding part removing water gap device 1 is in a standby working state and still needs to be accurately positioned so as to carry out the next working procedure.

It is further worth mentioning that the second sensing member 962 is electrically connected to the driving unit 911 for fine positioning of the injection molded part 980. Specifically, the second sensing member 962 of the driving unit 911 receives a signal of the relative position relationship between the nozzle 981 and the injection molded part 980, and adjusts the relative position relationship between the execution unit 912 and the nozzle 981 in real time, so as to ensure that the execution unit 912 can adjust the cutting position in real time when the execution unit 912 is in a cutting state, thereby increasing the cutting precision for the nozzle 981.

After the injection molding part automatic removing water gap device 1 removes the water gap 981, part of the water gap 981 still has recovery value. Therefore, the nozzle 981 can be recovered and utilized. The automatic injection molded part removal nozzle device 1 further comprises a separation structure 940, wherein the separation structure 940 is arranged below the injection molded part 980 to be processed so as to receive the nozzle 981 removed from the injection molded part 980. In one embodiment, the separating structure 940 has a separating cavity 941B adapted to receive the removed nozzle 981. In this embodiment, the separating structure 940 is optionally a box, and the separating structure 940 is open at the top to receive the removed nozzle 981 falling from top to bottom. The separating structure 940 has a larger opening to receive the nozzle 981. In another embodiment, the separation structure 940 has a separation channel 942A, which is arranged inside the injection molding 980 for holding the injection molding to be processed. In this embodiment, the injection molded part 980 is preferably a tubular injection molded part, and the separation structure 940 includes a separation body for receiving the injection molded part 980. In other words, the injection molded part 980 is sleeved on the separation body. Further, the separating body may be selected as a conveyor belt with a carrier. The bearing part is integrally connected to the conveying belt and arranged on the conveying belt at intervals. The carrier is optionally tubular, and the separation channel 942A extends from below and through the carrier from a top end surface of the carrier. That is, the separation channel 942A communicates the top and bottom of the carrier. The separation channel 942A is coaxial with the top of the injection molded part 980 sleeved on the carrier. The separation structure 940 further includes an aspirator 943B, and the aspirator 943B is communicated with the separation channel 942A. The aspirator 943B is for aspirating the removed nozzle 981 entering the separation passage 942A. In other words, the removed nozzle 981 is separated from the injection molded part 980, enters the separation channel 942A from top to bottom, and is attracted by the aspirator 943B from the separation channel 942A.

Specifically, the injection molded part 980 is sleeved on the carrier, and as the conveying belt conveys the injection molded part 980 to a belt processing position, the separation channel 942 coaxially corresponds to the removing structure 910 and the limiting structure 920. In other words, the center of the top surface of the injection molded part 980, i.e., the center of the nozzle 981, corresponds coaxially with the removal structure 910 and the stop structure 920. The injection molded part 980 is now ready for processing.

In another embodiment of the invention, the automatic injection molded part removal nozzle device 1 further comprises a plurality of auxiliary structures 950, in this embodiment, the position of the nozzle 981 is in the middle of two injection molded parts 980, that is, the nozzle 981 is at the joint of the injection molded parts 980 on both sides. In other words, the nozzle 981 connects the injection molded parts 980 on both sides. The injection molded parts 980 are transported on the conveyor belt. That is, the injection molded part 980 lays flat on the conveyor belt. At this time, the normal operation of the removing structure 910 is facilitated. The limiting structure 920 cannot completely fix the position of the injection molded part 980. At this time, the auxiliary structure 950 assists the limiting structure 920 in completing the fixing of the injection molding piece 980. In other words, the auxiliary structure 950, instead of the stop structure 920, is better for this type of nozzle 981, the preferred fixing means for the injection molded part 980.

The auxiliary structure 950 is disposed on the position-limiting structure 920, and the auxiliary structure 950 is located at two sides of the position-limiting structure 920. The sensing assembly 960 in this embodiment activates the auxiliary structure 950 upon receiving a change in the size of the injection molded part 980. When the lifting piece 933 of the positioning structure 930 drives the limiting structure 920 and the removing structure 910 to descend to a predetermined height, the auxiliary structure 950 is activated and fixed to the injection-molded parts 980 on both sides. The execution unit 912 is driven by the driving unit 911 to perform a high-precision cutting operation.

Further, the auxiliary structure 950 includes a plurality of suction cups 951 and a plurality of supports 954. The bottom of each supporting member 954 is correspondingly connected to each suction cup 951. That is, the suction cup 951 is connected to the position limiting structure 920 through the supporting member 954. The supporting member 954 plays a role of connecting and supporting. The suction cups 951 are adapted to be adsorbed to the outer surface of the injection molded part 980. The auxiliary structure 950 further includes a pumping unit 952 and an air hole 953. The pumping unit 952 is located on the support 954. The pumping unit 952 is adapted to pump away gas. The air holes 953 are disposed inside the suction cup 951, and the air pumping unit 952 is communicated with the air holes 953. That is, the pumping unit 952 is adapted to pump away the gas located within the suction cup 951.

It is worth mentioning that the sensing assembly 960 is also disposed on the auxiliary structure 950. The sensing element 960 is electrically connected to the auxiliary structure 950. When the support member 954 drives the suction cup 951 close to the injection molding 980, the sensing assembly 960 receives a signal that the suction cup 951 abuts against an outer surface of the injection molding 980. Further, the pumping unit 952 is also electrically connected to the sensing assembly 960. The sensing assembly 960 sends out a pumping signal to the pumping unit 952, and the pumping unit 952 operates to pump out the communicated air in the suction cup 951. The inner surface of the suction cup 951 is gradually pressed against the outer surface of the injection molded part 980. At this time, the environment inside the suction cup 951 tends to be vacuum, and the suction cup 951 receives pressure from the outside air, so that the suction cup 951 is tightly fixed on the outer surface of the injection molded part 980. Similarly, the auxiliary structure 950 on the other side also performs this operation, facilitating the subsequent removal of the nozzle 981 located in the middle of the injection-molded part 980 on both sides. After the nozzle 981 is removed by the removing structure 910, the injection-molded parts 980 on both sides are separated from each other, but the injection-molded parts 980 are still adsorbed by the suction cups 951. At this time, the sensing assembly 960 located in the removing structure 910 receives the signal that the water gap 981 is removed, and sends a stop signal to the air pumping unit 952, so that the air pumping unit 952 stops operating, the air pumping unit 952 returns the pumped gas, the gas returns from the gas hole 953 to the inside of the suction cup 951, so that the gas pressure inside the suction cup 951 is adjusted, and the suction cup 951 and the surface of the injection molding member 980 are separated from each other. In other words, the injection molded part 980 falls off the suction cup 951. The treated injection molded part 980 is placed on the conveyor belt and is transported before, and becomes a relatively qualified product. The removed gate 981 enters the separation structure 940.
