Therefore, when the beverage bottle cap is injection molded, the output end of the electric cylinder 13 on the support seat 12 is elongated, the second mold 14 is driven to approach and adhere to the first mold 1, the plurality of extrusion blocks 17 are inserted into the holes in the inside of the first mold 1, the inside of the first mold 1 is provided with a bottle cap mold cavity, the extrusion blocks 17 extrude the extrusion sliding plates 15 to slide on the inside side wall of the first mold 1, the first elastic member 16 is contracted under stress, the mold cavity of the circular bottle cap is formed, the four groups of connecting columns 11 are inserted into the inside of the second mold 14, the second mold 14 is provided with an injection pipe and is arranged in each group of extrusion blocks 17, the raw material is injected into the inside of the first mold 1 from the top end of the extrusion block 17, after the bottle cap is injection molded and cooled and formed, the output end of the electric cylinder 13 is retracted, the plurality of extrusion blocks 17 are pulled out of the inside of the first mold 1, the first elastic member 16 is reset and rebounds to extrude the extrusion sliding plate 15, the extrusion sliding plate 15 pushes the formed bottle cap outward, reduces the adhesion between the bottle cap and the mold, facilitates the demolding of the cover body, and thereby improves the production efficiency of the bottle cap.

When the extrusion slide plate 15 extrudes the lubricating oil, the extrusion force of the extrusion block 17 drives the lubricating oil stored in the oil storage groove to push open the sealing ball 21, the first elastic pull rope 2 is pulled and elongated, the lubricating oil overflows from the side wall of the first elastic pull rope 2 into the flow guide channel, and is pressed into the inside of the plurality of first sponge blocks 22. The brushes on the first sponge block 22 are coated with lubricating oil, and the inner wall of the first mold 1 is coated. After the bottle cap is injection molded, the lubricating effect of the lubricating oil is used to facilitate the demolding of the bottle cap. When the extrusion slide plate 15 is extruded, the plurality of first elastic pull ropes 2 pull the sealing ball 21 to seal the flow guide channel, and the evaporation of the lubricating oil in the oil storage groove is reduced.

[0032] The inside of the sealing ball 21 is fixedly connected with a magnetic ball 3; the inside of the extrusion slide plate 15 is fixedly connected with a plurality of magnetic strips 31, and is located at the sealing ball 21; the magnetic ball 3 and the magnetic strip 31 can be attracted to each other when they are close to each other; when the sealing ball 21 seals the lubricating oil in the oil storage groove, the magnetic ball 3 is fixedly connected with the plurality of magnetic strips 31 in the sealing ball 21 and is magnetically attracted, which further enhances the sealing effect of the lubricating oil. The magnetic attraction force between the magnetic ball 3 and the magnetic strip 31 is smaller than the extrusion force of the extrusion block 17 on the lubricating oil, so that the sealing ball can be punched out of the gap to leak the lubricating oil when the extrusion block 17 extrudes the lubricating oil. At the same time, the magnetic force between the magnetic ball 3 and the plurality of magnetic strips 31 plays a role in resetting and guiding the sealing ball 21 to quickly seal the flow guide channel.

[0033] The side wall of the magnetic ball 3 is fixedly connected with a push plate 4, and the push plate 4 is slidingly connected to the inner side wall of an extrusion sliding plate 15; the side wall of the push plate 4 is fixedly connected with a second elastic member 41; the inside of the extrusion sliding plate 15 is fixedly connected with a second sponge block 42, and is located below the second elastic member 41; when the lubricating oil in the flow guide channel accumulates, the extrusion force of the extrusion sliding plate 15 extruding the lubricating oil in the oil storage groove drives the sealing ball 21 to slide in the flow guide channel, at the same time, the push plate 4 extrudes the oil in the flow guide channel, the second elastic member 41 is extruded and stressed, the lubricating oil is extruded from the relatively thin channel to each first sponge block 22, and is attached to the brush to coat the inner wall of the first mold 1, so as to facilitate the demolding of the bottle cap, and when the push plate 4 extrudes the lubricating oil, the second sponge block 42 slows down the flow rate of the downward flow guide channel, and enhances the upwelling force of the lubricating oil, and when the second sponge block 42 is soaked, the lubricating oil will overflow to the first sponge block 22 below, so as to evenly distribute the lubricating oil.

[0034] The side wall of the push plate 4 is rotatably connected with a plurality of sets of sleeves 5; the side wall of the sleeve 5 is fixedly connected with stirring blades 51; the side wall of the push plate 4 is fixedly connected with a metal block 52; when the lubricating oil is stored in the flow guide channel for a long time, the lubricating oil in the oil storage cavity is extruded into the flow guide channel by the extrusion sliding plate 15, a large amount of lubricating oil quickly overflows to flush the plurality of stirring blades 51, and the plurality of stirring blades 51 rotate with the sleeves 5 to stir the lubricating oil, so as to stir the solidified lubricating oil.

[0035] As shown in Figures 2 to 5 The inner side wall of the push plate 4 is rotatably connected with a sealing plate 6 through a torsion spring; the side wall of the sealing plate 6 is fixedly connected with a rubber block 61; after the push plate 4 is extruded once, the lubricating oil overflows from the hole of the push plate 4 to the position of the second elastic member 41, in order to reduce the backflow of the lubricating oil when it overflows, the sealing plate 6 is clamped at the hole of the second mold 14 by the torsion spring, and the rubber block 61 cooperates to block the lubricating oil, the sealing plate 6 rotates with the torsion spring when the lubricating oil overflows, the lubricating oil can enter through the hole, but rarely overflows back, which has the effect of a one-way valve, reducing the backflow of the lubricating oil.

[0036] The bottom end of the sealing plate 6 is fixedly connected with a sealing gasket 7; the inside of the push plate 4 is fixedly connected with a second elastic pull rope 71, and one end of the second elastic pull rope 71 is fixedly connected with the sealing gasket 7; when the sealing plate 6 blocks the hole of the push plate 4, the sealing gasket 7 is fixed at the bottom end of the sealing plate 6 and is attached to the inner side wall of the push plate 4, which seals the hole of the push plate 4, and the second elastic pull rope 71 pulls the sealing gasket 7, which can quickly pull the sealing plate 6 back to the sealing position after the lubricating oil pushes the sealing plate 6 to overflow to the second elastic member 41, further improving the sealing effect of the hole of the push plate 4.

[0037] As shown in Figures 1 to 2As shown, the inner side wall of the second mold 14 is slidingly connected with a plurality of slide rods 8; the side wall of the slide rod 8 is sleeved with a third elastic piece 81; the top end of the slide rod 8 is fixedly connected with a demolding plate 82; a plurality of holes are formed in the interior of the demolding plate 82 and correspond to a plurality of extrusion blocks 17; when the beverage bottle cap is injection molded, the extrusion block 17 penetrates the demolding plate 82 and is pressed into the interior of the first mold 1, the demolding plate 82 abuts against the side wall of the first mold 1, the demolding plate 82 extrudes a plurality of third elastic pieces 81 to shrink under stress, and cooperates with the slide rod 8 to slide in the inner side wall of the second mold 14; when the molded bottle cap attached to the side wall of the extrusion block 17 is pulled out, the plurality of third elastic pieces 81 are reset, the extrusion block 82 is extruded and slides, the demolding plate 82 ejects the molded bottle cap on the plurality of extrusion blocks 17, and the molded bottle cap on the extrusion block 17 is quickly demolded.

[0038] The top end of the first mold 1 is provided with a material collecting groove 9; the material collecting groove 9 is located between the first mold 1 and the second mold 14; when a large number of beverage bottle caps are injection molded and attached to the side wall of the extrusion block 17, the demolding plate 82 extrudes a plurality of molded bottle caps and falls off, and the demolding plate 82 falls into the material collecting groove 9 between the first mold 1 and the second mold 14, the material collecting groove 9 is used for collecting the molded bottle cap, and the subsequent collection and detailed processing are facilitated.

[0039] Example two

[0040] As Figure 6 shown, the interior of the demolding plate 82 is provided with an oil storage cavity; the interior of the demolding plate 82 is fixedly connected with a third sponge block 91 and located in the oil storage cavity; the bottom end of the third sponge block 91 is fixedly connected with a plurality of brushes 92; when the beverage bottle cap is injection molded, the oil storage cavity in the interior of the demolding plate 82 is filled with lubricating oil, the lubricating oil wets the third sponge block 91 and flows to the plurality of brushes 92, when the extrusion block 17 penetrates the demolding plate 82 and is inserted into the interior of the first mold 1, the plurality of brushes 92 coat the lubricating oil on the side wall of the extrusion block 17, and after the injection molding of the bottle cap is completed, the adhesion degree of the bottle cap to the side wall of the extrusion block 17 is low, and the subsequent demolding work is facilitated.

[0041] The working principle is that when the existing beverage cover injection mold is processed, the raw liquid is injected into the mold, and after cooling and solidification, the shaped beverage bottle cap is easily tightly bonded with the mold, thereby causing the beverage bottle cap to be difficult to demold, and further affecting the production efficiency of the beverage bottle cap. Therefore, when the beverage bottle cap is injection molded, the output end of the electric cylinder 13 on the support seat 12 is elongated to drive the second mold 14 to approach and adhere to the first mold 1. A plurality of extrusion blocks 17 are inserted into the holes in the inside of the first mold 1. The inside of the first mold 1 is provided with a bottle cap cavity. The extrusion block 17 extrudes the extrusion slide plate 15 to slide on the inside wall of the first mold 1. The first elastic member 16 is contracted under stress. The bottle cap cavity is formed. Four groups of connecting columns 11 are inserted into the inside of the second mold 14 correspondingly. The second mold 14 is provided with an injection pipe inside and is arranged in each group of extrusion blocks 17. The raw material is injected into the inside of the first mold 1 from the top end of the extrusion block 17. When the bottle cap is injection molded and cooled and shaped, the output end of the electric cylinder 13 is retracted to drive a plurality of extrusion blocks 17 to pull out the inside of the first mold 1. The first elastic member 16 resets and rebounds to extrude the extrusion slide plate 15. The extrusion slide plate 15 pushes the shaped bottle cap outward. The adhesion between the bottle cap and the mold is reduced, which facilitates the demolding of the cover body, thereby improving the production efficiency of the bottle cap. When the beverage bottle cap is injection molded and adheres to the inner wall of the first mold 1, the extrusion block 17 extrudes the extrusion slide plate 15 to slide, generates strong thrust, drives the extrusion slide plate 15 to extrude the lubricating oil stored in the oil storage tank, and flows through the flow channel. When the extrusion slide plate 15 extrudes the lubricating oil, the extrusion force of the extrusion block 17 drives the lubricating oil stored in the oil storage tank to open the sealing ball 21. The first elastic pull rope 2 is pulled and elongated. The lubricating oil overflows from the side wall of the first elastic pull rope 2 into the flow channel and is pressed into the inside of a plurality of first sponge blocks 22. The brush on the first sponge block 22 is coated with lubricating oil and coated on the inner wall of the first mold 1. When the bottle cap is injection molded, the lubricating effect of the lubricating oil facilitates the demolding of the bottle cap. At the same time, when the extrusion slide plate 15 is extruded, a plurality of first elastic pull ropes 2 pull the sealing ball 21 to seal the flow channel, thereby reducing the evaporation of the lubricating oil in the oil storage tank. When the sealing ball 21 seals the lubricating oil in the oil storage tank, the magnetic ball 3 is fixed in the inside of the sealing ball 21 and is magnetically attracted to a plurality of magnetic strips 31, thereby further enhancing the sealing effect of the lubricating oil. The magnetic attraction force between the magnetic ball 3 and the magnetic strip 31 is less than the extrusion force of the extrusion block 17 on the lubricating oil, so that the sealing ball can be punched out of the gap to leak the lubricating oil when the extrusion block 17 extrudes the lubricating oil. At the same time, the magnetic force between the magnetic ball 3 and the plurality of magnetic strips 31 plays a role in resetting and guiding the sealing ball 21 to quickly seal the flow channel.When the lubricating oil accumulates inside the flow guide channel, the extrusion force of the extrusion slide 15 extruding the lubricating oil in the oil storage tank drives the sealing ball 21 to slide in the flow guide channel, and at the same time drives the push plate 4 to extrude the oil inside the flow guide channel. The second elastic member 41 is extruded and stressed. The lubricating oil is extruded to each first sponge block 22 from the relatively thin channel, adheres to the brush, and coats the inner wall of the first mold 1, facilitating the demolding of the bottle cap. When the push plate 4 extrudes the lubricating oil, the second sponge block 42 slows down the flow rate of the downward flow guide channel, enhancing the upward surge of the lubricating oil. When the second sponge block 42 is wet, the lubricating oil will only overflow to the first sponge block 22 below, achieving the effect of uniform distribution of the lubricating oil. When the lubricating oil is stored in the flow guide channel for a long time, the lubricating oil in the oil storage cavity is extruded into the flow guide channel by the extrusion slide 15. A large amount of lubricating oil quickly overflows and flushes the multiple stirring blades 51. The multiple stirring blades 51 rotate with the sleeve ring 5 to stir the lubricating oil, achieving the effect of stirring the solidified lubricating oil. After the push plate 4 is extruded once, the lubricating oil overflows from the hole of the push plate 4 to the position of the second elastic member 41. In order to reduce the backflow of the lubricating oil when it overflows, the sealing plate 6 is driven by the torsional spring to be clamped in the hole of the second mold 14, and cooperates with the rubber block 61 to block the lubricating oil. When the lubricating oil overflows, the extruded sealing plate 6 rotates with the torsional spring. The lubricating oil can enter through the hole, but rarely overflows back, achieving the effect of a one-way valve, reducing the backflow of the lubricating oil. When the sealing plate 6 blocks the hole of the push plate 4, the sealing gasket 7 is fixed at the bottom end of the sealing plate 6 and is attached to the inner side wall of the push plate 4, achieving the effect of sealing the hole of the push plate 4. The second elastic pull rope 71 can quickly pull the sealing gasket 7 back to the sealing position after the lubricating oil pushes the sealing plate 6 to overflow to the second elastic member 41, further improving the sealing effect of the hole of the push plate 4. When the beverage bottle cap is injection molded, the extrusion block 17 penetrates the demolding plate 82 and presses into the inside of the first mold 1. The demolding plate 82 is attached to the side wall of the first mold 1. The demolding plate 82 extrudes the multiple third elastic members 81 to shrink and stress, and cooperates with the slide rod 8 to slide on the inner side wall of the second mold 14. When the molded bottle cap attached to the side wall of the extrusion block 17 is pulled out, the multiple third elastic members 81 are extruded by the extrusion block 17 to slide and push out the molded bottle cap on the extrusion block 17, achieving the effect of quickly demolding the molded bottle cap on the extrusion block 17. When a large number of beverage bottle caps are injection molded and attached to the side wall of the extrusion block 17, the demolding plate 82 extrudes the multiple molded bottle caps to fall into the material collecting groove 9 between the first mold 1 and the second mold 14. The material collecting groove 9 achieves the effect of collecting the molded bottle caps for subsequent collection and detailed processing.When the beverage bottle cap is injection molded, the oil storage cavity inside the demolding plate 82 is filled with lubricating oil, the lubricating oil soaks the No. 3 sponge block 91, and is guided to the multiple sets of brushes 92, when the extrusion block 17 penetrates the demolding plate 82 and is inserted into the No. 1 mold 1, the multiple sets of brushes 92 coat the side wall of the extrusion block 17 with lubricating oil, after the bottle cap is injection molded, the adhesion degree with the side wall of the extrusion block 17 is low, and the subsequent demolding work is facilitated.
