Description

Technical Field

[0001] The invention relates to the technical field of injection molding shell processing, in particular to a spherical injection molding shell self-adaptive circumference grinding device. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds. The spherical injection molded shell is also called a spherical injection mold. It is an injection molded container used to produce spherical workpieces. It is usually composed of an upper and lower hemispherical injection molded shell. The spliced ​​spherical injection mold is more conducive to demoulding the workpiece. At the same time, the flatness of the inner and outer walls of the upper and lower hemispherical shells affects the quality of the spherical casting. For example, the patent CN220446124U discloses a device for polishing the inner wall of a hemispherical injection molded part, which polishes the inner wall of the injection molded part by the rotation of a grinding roller. However, the above patent document only has the effect of polishing the inner wall of the hemispherical injection molded part, and it is difficult to polish the outer wall of the hemispherical injection molded part. At the same time, during the clamping of the hemispherical injection molded part, in addition to the incision of the hemispherical injection molded part itself, it is also required that the closed end of the hemispherical injection molded part is provided with an open groove for clamping, which has certain restrictions on the structural shape of the hemispherical injection molded part itself, and cannot meet the size and structure requirements of most hemispherical injection molded parts, which greatly reduces the polishing efficiency of the overall spherical injection molded part.

The present invention is to set an adaptive limit mechanism, first use a cylinder to push the sinking adaptive limit mechanism to the semicircular injection molding shell, one end of a plurality of racks respectively corresponds to the inner wall of the top opening of the hemispherical shell, and the second motor drives the gear roller to rotate clockwise, which rotates counterclockwise with the gear ring, and the teeth on the inner wall of the gear ring mesh with the plurality of gear rollers to rotate, and force the plurality of racks to penetrate the outside of the outer ring frame respectively, and respectively press against the inner wall of the hemispherical injection molding shell, so as to achieve the clamping and limiting of the hemispherical injection molding shell; At the same time, two sets of arc scrapers also follow the cylinder into the interior of the hemispherical injection molded shell, and adaptively stick to the hemispherical injection molded shell.

[0019] Example 2: Please refer to Figure 5 and Figure 6As shown, the adaptive limit mechanism 6 also includes a vertical rod 68, which is arranged through the center of the gear ring disk 61, the top of the vertical rod 68 is fixedly connected to the bottom surface of the top plate 3, and the bottom thereof extends to the bottom of the inner ring frame 63 and is sleeved with a tube 69, a damping spring shock absorbing ring 610 is commonly arranged between the vertical rod 68 and the inner wall of the bottom of the tube 69, an open groove is arranged at the bottom of the tube 69, and two groups of arc scrapers 611 are hinged inside the open groove, and an inclined tension spring group 612 is commonly arranged between the inner walls of the two groups of arc scrapers 611 and the two side surfaces of the tube 69 respectively; When the adaptive limit mechanism 6 sinks to the top opening of the hemispherical injection molded shell, the cylinder 69 is inserted into the hemispherical injection molded shell in a straight line until the bottom end of the cylinder 69 contacts the bottom inner wall of the hemispherical injection molded shell, and automatically presses the bottom of the cylinder 69 according to the sinking position of the rack 64 to compress the damping spring shock absorbing ring 1 610. At the same time, the two groups of arc-shaped scrapers 611 also enter the hemispherical injection molded shell with the cylinder 69 and adaptively stick to the hemispherical injection molded shell. The tension spring group 612 is stretched or compressed to further adaptively press the inner cavity of the hemispherical injection molded shell. This embodiment is combined with the first embodiment. When the motor 1 5 is started, one of the limit gears 4 is driven to rotate. Under the meshing action, the gear ring disk 61 and the hemispherical injection molded shell rotate, and the hemispherical injection molded shell rotates relative to the two sets of arc scrapers 611. Thus, the two sets of arc scrapers 611 are used to adaptively scrape the inner wall of the hemispherical injection molded shell to keep the inner wall surface of the hemispherical injection molded shell smooth. The adaptive limiting mechanism 6 can not only adaptively clamp hemispherical injection-molded shells of various sizes, but also grind the inner wall of the clamped hemispherical injection-molded shells.

[0020] Example 3: Please refer to Figure 7 - Figure 8 As shown, the adaptive grinding mechanism 7 includes a fixed square frame 71, and a positioning frame 72 is fixedly installed at the center of the inner wall of the front and rear sides of the fixed square frame 71, and a T-shaped push rod 73 is penetrated at the center of one side of the positioning frame 72 away from the inner wall of the fixed square frame 71, and a grinding turntable 74 is fixedly installed on the top surface of the T-shaped push rod 73 and at one end extending outside the positioning frame 72, and a damping spring shock absorbing ring 75 is commonly arranged between the end of the T-shaped push rod 73 away from the grinding turntable 74 and the corresponding inner wall of the positioning frame 72, and an inner slide groove is arranged inside the T-shaped push rod 73; The inner wall at the bottom of the positioning frame 72 is fixedly installed with a sliding shaft 76 at the through end of the T-shaped push rod 73. The sliding shaft 76 is slidably connected inside the inner slide groove. The T-shaped push rod 73 is resisted and penetrates into the interior of the positioning frame 72. The damping spring shock absorbing ring 2 75 is compressed, and the sliding shaft 76 moves relative to the East China City along the inner slide groove, thereby maintaining the stable displacement of the T-shaped push rod 73 and the frosted turntable 74 and reducing the offset. The grinding process using the adaptive grinding mechanism 7 specifically includes: when the hemispherical injection molded shell is limited, the bottom of the hemispherical injection molded shell is supported by four sets of grinding turntables 74 as the bottom, thereby increasing the stability of the hemispherical injection molded shell; Then the motor 15 drives the limit gear 4, the gear ring disk 61 and the hemispherical injection molding shell to rotate, and the bottom surface of the hemispherical injection molding shell rotates relative to the four groups of frosted turntables 74 and performs friction grinding. As the cylinder 2 is started, it uses the push rod to continuously push the top plate 3, the adaptive limit mechanism 6 and the clamped hemispherical injection molding shell to settle. The bottom surface of the hemispherical injection molding shell presses the four groups of frosted turntables 74 and forces them to move away from each other. The frosted turntable 74 pushes the corresponding T-shaped push rod 73 to penetrate the inside of the positioning frame 72, and the damping spring shock-absorbing ring 2 75 is compressed. The hemispherical injection molding shell gradually penetrates between the four groups of frosted turntables 74. As the hemispherical shell continues to settle, the four groups of frosted turntables 74 are forced to stay at different height positions on the surface of the hemispherical shell in turn. Then, with the help of the hemispherical injection molding shell rotating and rubbing against the side walls of the four groups of frosted turntables 74, the outer wall curved surface of the hemispherical injection molding shell is polished, and the separation of the hemispherical injection molding shell during the grinding process is reduced; This embodiment is based on the second embodiment, and the two cooperate to achieve continuous grinding of the inner and outer walls of the hemispherical injection-molded shell to improve the grinding efficiency of the spherical injection-molded shell; It is worth noting that a chassis 77 is commonly provided at the bottom of the four groups of frosted turntables 74, and a hollow groove is provided in the center of the chassis 77.

A support bar 79 is hingedly connected to the top surface of the chassis 77 located at the front and rear ends and both sides of the hollow groove. The top surface of the support bar 79 is provided with a frosted surface, and one end of the support bar 79 extends to the inside of the hollow groove. As the hemispherical injection molded shell continues to sink and polish, its bottom end first penetrates the bottom of the fixed frame 71 and sinks to the surface of the chassis 77, and the chassis 77 is resisted from sinking and causes the damping spring shock absorbing ring 3 78 to be compressed, so as to provide stable support for the hemispherical injection molded shell in the grinding and sinking state; During this process, the bottom of the hemispherical injection molded shell moves toward the hollow groove of the chassis 77, and the bottom of the hemispherical injection molded shell first contacts the frosted surface of the four groups of abutment strips 79, and under the action of the rotation of the injection molded shell, the four groups of abutment strips 79 rub against each other to assist in scraping off the waste debris on the bottom surface of the hemispherical injection molded shell; As the hemispherical injection molded shell continues to sink, its bottom simultaneously presses against one end of four groups of anti-bars 79 and forces the anti-bars 79 to tilt up, so that the four groups of inclined anti-bars 79 adaptively press against the side wall of the hemispherical injection molded shell, and cooperate with the rotation of the shell to scrape the waste chips on the outside of the semicircular injection molded shell in turn, further enhancing the polishing effect of the outer wall of the hemispherical injection molded shell and improving the processing efficiency of the spherical injection molded shell.

[0021] Working principle: When the present invention is used, the upper or lower hemispherical injection-molded shell is first placed at the top center of the adaptive grinding mechanism 7, and then the cylinder 2 is started to use the push rod to push the top plate 3 and the adaptive limit mechanism 6 to settle until the adaptive limit mechanism 6 settles to the notch on the top surface of the hemispherical shell, and then the hemispherical injection-molded shell is clamped and limited by the adaptive limit mechanism 6; The limiting process of the hemispherical injection molded shell by the adaptive limiting mechanism 6 specifically includes: the ends of several groups of racks 64 close to the outside correspond to the inner wall of the top opening of the hemispherical shell respectively, then the motor 2 67 drives one group of gear rollers 66 to rotate clockwise, and it and the gear ring 65 make counterclockwise circular motion along the inner wall of the outer ring frame 62, and the inner wall teeth of the gear ring 65 are meshed with the remaining groups of gear rollers 66 at the same time, so that multiple groups of gear rollers 66 rotate clockwise, and the bottom of each group of gear rollers 66 is meshed with the rack 64 respectively, forcing several groups of racks 64 to penetrate the outside of the outer ring frame 62 respectively, and respectively press against the inner wall of the hemispherical injection molded shell, so as to achieve the clamping and limiting of the hemispherical injection molded shell; At the same time, the cylinder 69 is inserted into the hemispherical injection molded shell in a straight line until the bottom end of the cylinder 69 contacts the bottom inner wall of the hemispherical injection molded shell, and the two sets of arc scrapers 611 also enter the hemispherical injection molded shell with the cylinder 69 and adapt to the hemispherical injection molded shell. The two sets of arc scrapers 611 also enter the hemispherical injection molded shell with the cylinder 69 and adapt to the hemispherical injection molded shell. The grinding process of the adaptive grinding mechanism 7 specifically includes: the bottom of the hemispherical injection molding shell is supported by four groups of frosted turntables 74 as the bottom, the motor 1 5 drives the limit gear 4, the gear ring disk 61 and the hemispherical injection molding shell to rotate, and the bottom surface of the hemispherical injection molding shell rotates relative to the four groups of frosted turntables 74 and performs friction grinding; the cylinder 2 is used to continuously push the clamped hemispherical injection molding shell to settle, and the bottom surface of the hemispherical injection molding shell presses the four groups of frosted turntables 74 to force them to move away from each other, and the frosted turntables 74 push the corresponding T-shaped push rods 73 to penetrate the inside of the positioning frame 72, and the damping spring shock-absorbing ring 2 75 is compressed, and the hemispherical injection molding shell gradually penetrates between the four groups of frosted turntables 74, and with the continuous settlement of the hemispherical shell, the four groups of frosted turntables 74 are forced to stay at different height positions on the surface of the hemispherical shell in turn, and then the hemispherical injection molding shell rotates and rubs against the side walls of the four groups of frosted turntables 74, so as to grind the outer wall curved surface of the hemispherical injection molding shell; At the same time, the bottom end of the hemispherical injection-molded shell first penetrates the bottom of the fixed square frame 71 and sinks to the surface of the chassis 77, and the chassis 77 is resisted and sinks, causing the damping spring shock-absorbing ring 3 78 to be compressed, so as to provide stable support for the hemispherical injection-molded shell in the grinding and sinking state; the bottom of the hemispherical injection-molded shell moves toward the hollow groove of the chassis 77, and the bottom of the hemispherical injection-molded shell first contacts the frosted surface of the four groups of resisting strips 79, and under the action of the self-rotation of the injection-molded shell, the four groups of resisting strips 79 rub against each other to assist in scraping off the waste chips on the bottom surface of the hemispherical injection-molded shell; the continuous sinking of the hemispherical injection-molded shell causes its bottom to press against one end of the four groups of resisting strips 79 at the same time, forcing the resisting strips 79 to tilt, so that the four groups of inclined resisting strips 79 are adaptively pressed against the side wall of the hemispherical injection-molded shell, and scrape the waste chips on the outside of the injection-molded shell in turn in coordination with the self-rotation of the shell; Finally, after the inner and outer walls of the hemispherical injection molded shell are polished, the motor 2 67 drives the gear roller 66 to rotate in the opposite direction, forcing the rack 64 to reversely transmit and lose the pressure on the inner wall of the hemispherical injection molded shell. As a result, the hemispherical injection molded shell loses its clamping and is removed, and another set of hemispherical injection molded shells is replaced to repeat the above steps to achieve the polishing of the entire spherical injection molded shell.
