Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a bottle cap compression molding equipment and its working method. Background Technology

[0002] Bottle caps for mineral water or beverage bottles are formed by compression molding using a bottle cap compression molding machine. The compression molding machine has multiple sets of compression molds arranged around its circumference, which sequentially complete the compression molding of the blank as the machine revolves. During the compression molding process, the molds are cooled to allow the bottle caps to cool and solidify quickly.

[0003] After the bottle cap is shaped, demolding is required. Currently, this is often achieved by rotating the core inside the mold to separate the internal threads of the bottle cap from the mold. During the shaping and separation stages, the mold needs to continuously dissipate heat. Rapid cooling of the mold can help the bottle cap shape quickly and increase processing speed. In addition, rapid heat dissipation can also reduce the problems of jamming of the internal threads of the bottle cap, demolding, and sticking to the mold.

[0004] Traditional bottle cap molds have a relatively simple coolant flow channel structure, with the coolant mostly flowing in a static layer. When the coolant flows, a stable boundary layer forms in the part that contacts the inner wall, resulting in low heat transfer efficiency and limited cooling effect. Especially under high-speed continuous molding conditions, the core heat accumulates quickly, which can easily lead to problems such as localized high temperature and uneven temperature distribution. This causes problems such as slow shaping speed in some parts of the bottle cap, reduced thread accuracy, and easy jamming during demolding. In the continuous bottle cap compression molding process, the uniform and rapid cooling of the compression mold is closely related to the quality of the bottle cap. Summary of the Invention

[0005] This invention proposes a bottle cap compression molding equipment and its working method to solve the problem of insufficient and uneven cooling inside the mold during continuous bottle cap compression molding in related technologies, which affects the quality and efficiency of bottle cap processing.

[0006] The technical solution of the present invention is as follows:

[0007] A bottle cap compression molding device includes a bottle cap compression molding machine. Multiple compression molds are arranged circumferentially on the bottle cap compression molding machine. The compression molds are rotatable around the bottle cap compression molding machine. The bottle cap compression molding machine is equipped with an extrusion track assembly and an arc-shaped cap release assembly. The extrusion track assembly includes an upper extrusion track and a lower extrusion track. Each compression mold includes a concave mold mechanism and a convex mold mechanism. The concave mold mechanism is fixedly connected to the bottle cap compression molding machine and contacts the lower extrusion track. The concave mold mechanism includes a concave mold. The convex mold mechanism is fixedly connected to the bottle cap compression molding machine and is positioned above the corresponding concave mold mechanism. The mechanism contacts the upper extrusion track. The punch mechanism includes a convex mold. When the concave mold is in contact with the convex mold, it can compress and mold the blank. The punch mechanism is provided with a threaded sleeve. The threaded sleeve is slidably connected to the convex mold and can rotate synchronously. When the threaded sleeve contacts the arc-shaped cap removal assembly, it can rotate and drive the convex mold to rotate and slide. The convex mold is provided with a liquid supply channel and a liquid discharge channel. The liquid supply channel is eccentrically set with the axis of the convex mold. The liquid discharge channel is provided with a spiral guide groove for driving the coolant to flow when the convex mold rotates.

[0008] The convex mold is provided with a heat dissipation core, the liquid supply channel is opened inside the heat dissipation core, the liquid discharge channel is arranged between the heat dissipation core and the convex mold, the liquid supply channel and the liquid discharge channel are connected at one end near the concave mold, and the spiral guide groove is opened on the heat dissipation core at one end near the convex mold.

[0009] When the heat dissipation core rotates with the convex mold, the coolant in the drain channel also rotates due to the eccentric setting of the liquid supply channel and the center of the convex mold. The rotation of the spiral guide groove drives the coolant in the drain channel to flow away from the concave mold. Simultaneously with the rotation of the convex mold, the eccentric liquid supply channel causes the coolant to swirl, disrupting the boundary layer and enhancing the heat conduction effect of the coolant. The threads connecting the convex mold and the bracket are opposite in direction to the spiral guide groove, so that when the convex mold rotates and separates from the cap, the rotation direction of the spiral guide groove can accelerate the flow of coolant away from the concave mold, thereby enhancing the flow of coolant and disrupting the boundary layer. An arc-shaped guide groove is provided on the heat dissipation core at the position where the liquid supply channel and the drain channel connect, which can guide the flow of coolant.

[0010] The punch mechanism also includes a bracket, a sliding abutment seat, and a rotating connector. The bracket is fixedly connected to the bottle cap compression molding machine, and the threaded sleeve is rotatably connected to the bracket. Openings are provided on both sides of the bracket to facilitate contact between the threaded sleeve and the arc-shaped cap removal assembly. The punch mold is threadedly connected to the bracket, and the sliding abutment seat is slidably connected to the bracket. The sliding abutment seat cannot rotate when sliding on the bracket. An infusion tube is connected to the rotating connector. When the punch mold rotates, the rotating connector does not rotate but only slides longitudinally. A roller is rotatably connected to the sliding abutment seat. The rotating connector is rotatably connected to the punch mold. The liquid supply channel and the liquid discharge channel are both connected to the rotating connector. The rotating connector is connected to the sliding abutment seat. When the punch mold rotates, it can drive the sliding abutment seat to slide on the bracket.

[0011] The convex mold, with one end near the concave mold passing through the hanger, can extend into the concave mold. The convex mold, the concave mold, and the hanger together compress and shape the bottle cap blank.

[0012] The arc-shaped cap removal assembly includes an arc-shaped toothed plate one, an arc-shaped toothed plate two, and an arc-shaped toothed plate three, all of which are fixedly connected to the bottle cap compression molding machine. When the threaded sleeve contacts the arc-shaped toothed plate one and the arc-shaped toothed plate three, it rotates, which can drive the convex mold to move towards the concave mold. When the threaded sleeve contacts the arc-shaped toothed plate two, it rotates, which can drive the convex mold to move away from the concave mold. When the threaded sleeve rotates with the bracket, it contacts the arc-shaped toothed plate one, the arc-shaped toothed plate two, and the arc-shaped toothed plate three in sequence.

[0013] When the convex mold slides toward the concave mold, it can cause the bottle cap to separate from the hanger. When the convex mold slides away from the concave mold, the bottle cap abuts against the hanger, and the convex mold and the bottle cap rotate and separate.

[0014] Both the upper extrusion track and the lower extrusion track are provided with corresponding pressure relief sections. The arc-shaped cap removal component is positioned corresponding to the pressure relief section. When the convex mold slides on the hanger, it is in the pressure relief section position. At the pressure relief section position, the concave mold moves to a position away from the convex mold.

[0015] A method for operating a bottle cap compression molding equipment, using the aforementioned bottle cap compression molding equipment, includes the following steps:

[0016] Step 1: Adding the blank: Add the bottle cap blank to the concave mold at the loosening section;

[0017] Step 2, Compression Molding: When the concave mold moves, it is pushed upward by the lower extrusion track and abuts against the hanger. The concave mold, convex mold and hanger work together to compress the bottle cap blank.

[0018] Step 3, Rotation and Separation: When the compression mold rotates to the loosening section, the concave mold moves away from the convex mold, and the threaded sleeve contacts the arc-shaped toothed plate, causing the convex mold to move towards the concave mold, thus separating the bottle cap from the hanger;

[0019] Step 4, Rotation and Demolding: After the threaded sleeve separates from the first arc-shaped toothed plate, it contacts the second arc-shaped toothed plate, causing the convex mold to move away from the concave mold, and the bottle cap separates from the convex mold;

[0020] Step 5, Enhanced Cooling: When the convex mold rotates, the coolant is thrown in the supply channel, and the spiral guide groove drives the coolant to flow in the discharge channel;

[0021] Step 6: Mold Reset: After the threaded sleeve comes into contact with the arc-shaped toothed plate, it drives the convex mold to slide to a position where it can compress the concave mold.

[0022] The working principle and beneficial effects of this invention are as follows:

[0023] 1. In this invention, the coolant in the supply channel is rotated along with the convex mold when the convex mold rotates. The coolant is thrown by centrifugal force, which causes the coolant to flow irregularly in the supply channel, thereby destroying the boundary layer that would be formed during static transport in the supply channel and improving the heat dissipation effect.

[0024] 2. In this invention, by setting a spiral guide groove, when the convex mold rotates to twist and separate the bottle cap, the spiral guide groove rotates and drives the coolant in the drain channel to flow faster. At the same time, the spiral guide groove can also drive the coolant in the drain groove to break the boundary layer, thereby accelerating the flow of coolant and improving heat dissipation efficiency.

[0025] 3. In this invention, by setting up a liquid supply channel and a spiral guide groove, the flow channel of the coolant is agitated and the flow speed of the coolant is accelerated during each compression molding of the convex mold, thereby accelerating the heat dissipation efficiency of the bottle cap and the mold. Compared with the heat dissipation channels in traditional bottle cap molds, which are mostly set as symmetrical structures, the coolant is kept statically transported when the mold rotates, and the boundary layer heat insulation is easily formed at the position in contact with the inner wall. This application can destroy the boundary layer of the coolant, improve the heat dissipation efficiency, and thus improve the quality of the bottle cap and the compression molding efficiency.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1 to 9As shown, this embodiment proposes a bottle cap compression molding equipment, including a bottle cap compression molding machine 1. Multiple compression molds are arranged circumferentially on the bottle cap compression molding machine 1, and the compression molds can rotate around the bottle cap compression molding machine 1. The bottle cap compression molding machine 1 is equipped with an extrusion track group and an arc-shaped cap release component. The extrusion track group includes an upper extrusion track 2 and a lower extrusion track 3. The compression mold includes a concave mold mechanism and a convex mold mechanism. The concave mold mechanism is fixedly connected to the bottle cap compression molding machine 1 and contacts the lower extrusion track 3. The concave mold mechanism includes a concave mold 4. The convex mold mechanism is fixedly connected to the bottle cap compression molding machine 1 and is positioned above the corresponding concave mold mechanism. The punch mechanism is in contact with the upper extrusion track 2. The punch mechanism includes a punch mold 5. When the concave mold 4 is in contact with the punch mold 5, it can compress and mold the blank. The punch mechanism is provided with a threaded sleeve 6. The threaded sleeve 6 is slidably connected to the punch mold 5 and can rotate synchronously. When the threaded sleeve 6 is in contact with the arc-shaped cap removal component, it can rotate on its own and drive the punch mold 5 to rotate and slide in the axial direction. The punch mold 5 is provided with a liquid supply channel 7 and a liquid discharge channel 8. The liquid supply channel 7 is eccentrically set with the axis of the punch mold 5. The liquid discharge channel 8 is provided with a spiral guide groove 9, which is used to drive the coolant to flow when the punch mold 5 rotates.

[0040] like Figures 8 to 9 As shown, a heat dissipation core 10 is provided in the convex mold 5, a liquid supply channel 7 is opened inside the heat dissipation core 10, and a liquid discharge channel 8 is arranged between the heat dissipation core 10 and the convex mold 5. The liquid supply channel 7 and the liquid discharge channel 8 are connected at one end near the concave mold 4. A spiral guide groove 9 is opened on the heat dissipation core 10 at one end near the convex mold 5, as shown. Figure 7 As shown, the two threads on the convex mold 5 that are being pressed and the threaded connection to the hanger 11 are twisted in the same direction. When the convex mold 5 twists away from the concave mold 4, the bottle cap can be twisted and separated simultaneously.

[0041] When the heat sink 10 rotates with the convex mold 5, due to the eccentric setting of the liquid supply channel 7 and the center of the convex mold 5, such as Figure 8 As shown, the coolant in the drain channel 8 also rotates. When the spiral guide groove 9 rotates, it can drive the coolant in the drain channel 8 to flow away from the concave mold 4. At the same time as the convex mold 5 rotates, the coolant is thrown through the eccentric supply channel 7, which breaks the boundary layer and enhances the heat conduction effect of the coolant. Figures 8 to 9 As shown, the thread connecting the convex mold 5 and the hanger 11 is opposite in direction to the spiral guide groove 9. This allows the spiral guide groove 9 to rotate and separate from the bottle cap, thus accelerating the flow of coolant away from the concave mold 4 when the convex mold 5 rotates, thereby enhancing the flow of coolant and disrupting the boundary layer. An arc-shaped guide groove is provided on the heat dissipation core 10 at the position where the supply channel 7 and the drain channel 8 connect, which can guide the flow of coolant. Figure 8 As shown, the diameter of the through hole at the connection between the liquid supply channel 7 and the liquid drain channel 8 is small, which can increase the flow rate of the coolant when it flows through the through hole.

[0042] like Figures 4 to 7 As shown, the punch mechanism also includes a bracket 11, a sliding abutment seat 12, and a rotating connector 14. The bracket 11 is fixedly connected to the bottle cap compression molding machine 1, and the threaded sleeve 6 is rotatably connected to the bracket 11. The threaded sleeve 6 has annular protrusions on its outside. Openings are provided on both sides of the bracket 11 to facilitate contact between the threaded sleeve 6 and the arc-shaped cap removal component. The punch mold 5 is threadedly connected to the bracket 11, and the sliding abutment seat 12 is slidably connected to the bracket 11. When the sliding abutment seat 12 slides on the bracket 11, it cannot move. The rotating connector 14 is connected to an infusion tube. When the convex mold 5 rotates, the rotating connector 14 does not rotate but only slides longitudinally. A roller 13 is rotatably connected to the sliding abutment seat 12. The rotating connector 14 is rotatably connected to the convex mold 5. The infusion channel 7 and the infusion channel 8 are both connected to the rotating connector 14. The rotating connector 14 is connected to the sliding abutment seat 12. When the convex mold 5 rotates, it can drive the sliding abutment seat 12 to slide on the hanger 11.

[0043] The end of the convex mold 5 near the concave mold 4 passes through the hanger 11 and can extend into the concave mold 4, such as... Figure 4 As shown, the convex mold 5 passes through the concave mold 4 on the pendant, and the convex mold 5 and the concave mold 4 can compress and shape the bottle cap blank at this point.

[0044] like Figures 1 to 3 As shown, the arc-shaped cap removal assembly includes an arc-shaped toothed plate 15, an arc-shaped toothed plate 2 16, and an arc-shaped toothed plate 3 17, all fixedly connected to the bottle cap compression molding machine 1. When the threaded sleeve 6 contacts the arc-shaped toothed plate 15 and the arc-shaped toothed plate 3 17, it rotates, which can drive the convex mold 5 to move towards the concave mold 4, as shown. Figure 5 As shown, when the threaded sleeve 6 rotates in contact with the second arc-shaped toothed plate 16, it can drive the convex mold 5 to move away from the concave mold 4. As the threaded sleeve 6 rotates with the bracket 11, it sequentially contacts the first arc-shaped toothed plate 15, the second arc-shaped toothed plate 16, and the third arc-shaped toothed plate 17, as shown. Figure 3 As shown, the arc-shaped toothed plate 15, arc-shaped toothed plate 2 16, and arc-shaped toothed plate 3 17 are respectively arranged on both sides of the bracket 11. They come into contact with each other in sequence when the compression mold rotates, and will not come into contact with two toothed plates at the same time. Since they are respectively arranged on both sides of the bracket 11, the rotation direction of the threaded sleeve 6 when it comes into contact with the arc-shaped toothed plate 15 and the arc-shaped toothed plate 3 17 is opposite to the rotation direction of the threaded sleeve 6 when it comes into contact with the arc-shaped toothed plate 2 16.

[0045] When the convex mold 5 slides towards the concave mold 4, it can cause the bottle cap to separate from the hanger 11. When the convex mold 5 slides away from the concave mold 4, the bottle cap abuts against the hanger 11, and the convex mold 5 and the bottle cap rotate and separate.

[0046] like Figure 1-2 As shown, both the upper extrusion track 2 and the lower extrusion track 3 are provided with corresponding pressure release sections 18. The arc-shaped cap removal component is positioned corresponding to the pressure release section 18. When the convex mold 5 slides on the hanger 11, it is in the pressure release section 18 position. In the pressure release section 18 position, the concave mold 4 moves to a position away from the convex mold 5. When the threaded sleeve 6 contacts the arc-shaped toothed plate 15, arc-shaped toothed plate 2 16 and arc-shaped toothed plate 3 17, the sliding abutment seat 12 can drive the roller 13 to move vertically. In the pressure release section 18, the upper extrusion track 2 can avoid affecting the sliding of the sliding abutment seat 12. The concave mold 4 is set on the lower pressure column 19. The lower pressure column 19 is slidably set on the bottle cap compression machine 1. The lower pressure column 19 is rotatably connected to the lower roller 20. A spring is sleeved on the lower pressure column 19. The spring push makes the roller 20 fit with the lower extrusion track 3.

[0047] In this embodiment, the arrangement of the arc-shaped toothed plate 15, the arc-shaped toothed plate 16, and the arc-shaped toothed plate 17 allows the convex mold 5 to rotate sequentially in the forward, reverse, and forward directions. First, it causes the bottle cap to separate from the hanger 11, and then it causes the bottle cap to separate from the convex mold 5. The convex mold 5 is then rotated and reset for the next compression molding. When the convex mold 5 rotates, the internal heat dissipation core 10 rotates accordingly, causing the heat dissipation channel to cause the coolant to rotate eccentrically. At the same time, the rotation of the spiral guide groove 9 accelerates the flow of the coolant in the drain channel 8. By swinging the coolant and accelerating its flow, the boundary layer generated during the static flow of the coolant is broken, thereby improving the heat dissipation efficiency.

[0048] Example 2

[0049] A method for operating a bottle cap compression molding equipment, using the aforementioned bottle cap compression molding equipment, includes the following steps:

[0050] Step 1: Adding blank: Add the bottle cap blank to the concave mold 4 at the loosening section 18;

[0051] Step 2, Compression Molding: When the concave mold 4 moves, it is pushed upward by the lower extrusion track 3 and abuts against the hanger 11. The concave mold 4, the convex mold 5 and the hanger 11 work together to compress the bottle cap blank.

[0052] Step 3, Rotation and Separation: When the compression mold rotates to the loosening section 18, the concave mold 4 moves away from the convex mold 5, the threaded sleeve 6 contacts the arc-shaped toothed plate 15, and drives the convex mold 5 to move towards the concave mold 4, and the bottle cap separates from the hanger 11.

[0053] Step 4, Rotation and Demolding: After the threaded sleeve 6 separates from the arc-shaped toothed plate 15, it contacts the arc-shaped toothed plate 2 16, causing the convex mold 5 to move away from the concave mold 4, and the bottle cap separates from the convex mold 5.

[0054] Step 5, Enhanced Cooling: When the convex mold 5 rotates, the coolant is thrown in the supply channel 7, and the spiral guide groove 9 drives the coolant to flow in the discharge channel 8;

[0055] Step 6, Mold Reset: After the threaded sleeve 6 contacts the arc-shaped toothed plate 3 17, it drives the convex mold 5 to slide to a position where it can compress the concave mold 4.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
