DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0021] Embodiment: A UV glue bottle forming device, such as Figure 1 、 Figure 5 and Figure 6As shown, it includes a base 1, and cylinders 3 are symmetrically arranged on the left and right sides of the top of the base 1 through supporting feet 301. The movable end of the piston rod of the cylinder 3 is connected to a U-shaped block 302. The two symmetrical U-shaped blocks 302 are movably connected to the symmetrical half molds 5 through the U-shaped connecting plate 11. A placement rack 2 is provided on the top of the base 1 for placing the molten extruded billet so as to press it into the cavity of the two enclosed half molds 5. The placement rack 2 is placed between the two cylinders 3. The second guide rod 801 and the two-way push rod 802 are parallel between the upper and lower ends of the U-shaped block 302 facing the half mold 5. Both ends of the two-way push rod 802 are connected to a lifting block 803. The lifting block 803 slides with the second guide rod 801 and moves up and down along the second guide rod 801. 803 is provided with a pin 8 which movably cooperates with the socket provided on the side wall protrusion of the half mold 5. The U-shaped block 302 is detachably connected to the half mold 5 by means of the pin 8 and the socket being plugged in and cooperated with the said socket. The half mold 5 can be conveniently replaced by the detachable cooperation between the pin 8 and the socket on the side wall protrusion of the half mold 5, so as to adapt to the appearance of different UV glue bottles, thereby realizing the molding operation of UV glue bottles with different appearances; when the piston rods of the two cylinders 3 are extended, the half molds 5 movably connected to the U-shaped block 302 are close to each other and enclose to form a structure with a top opening and a accommodating space in the middle. When the two half molds 5 are enclosed to form the mold of the UV glue bottle, the center point of the top opening is on the same straight line as the line connecting the center point of the placement rack 2 and the center point of the base 1.

[0022] When the mold half 5 needs to be replaced, the piston rod of the cylinder 3 is retracted, thereby driving the mold half 5 to move toward the cylinder 3 through the U-shaped block 302, the connecting plate 11, the second guide rod 801, the two-way push rod 802 and the lifting block 803, thereby separating the two enclosed mold half 5. Subsequently, the two-way push rod 802 is retracted, and the two-way push rod 802 drives the lifting blocks 803 installed at the upper and lower ends thereof to approach, thereby making the latch 8 away from the socket on the protrusion of the side wall of the mold half 5, so that the latch 8 is separated from the socket on the protrusion of the side wall of the mold half 5, and then the mold half 5 is separated from the latch 8. At this time, the mold half 5 can be replaced. After replacing the mold half 5, the latch 8 is inserted into the socket on the protrusion of the side wall of the new mold half 5 by the two-way push rod 802, thereby fixing the new mold half 5. Subsequently, the piston rod of the cylinder 3 is extended, thereby making the two mold halves 5 enclosed to form a mold of the UV glue bottle, thereby realizing flexible replacement of the molding half mold 5 of the UV glue bottle according to needs.

[0023] like Figure 2 and Figure 4As shown, a hollow tube 6 is slidably connected to the midpoint line of the base 1 through an inverted L-shaped plate 101, and a through hole connected to the inner cavity of the hollow tube 6 is opened on the circumferential wall of the hollow tube 6. When the two half molds 5 are close to each other and enclosed, the hollow tube 6 is opposite to the top opening of the two half molds 5, and the hollow tube 6 can extend into the internal cavity enclosed by the two half molds 5 through the opening. The top of the hollow tube 6 is connected to the air outlet end of the first air pump 4 installed on the inverted L-shaped plate 101 through a telescopic hose 602. The first air pump 4 compresses the air and pours it into the hollow tube 6 through the telescopic hose 602. The air is then input into the mold cavity enclosed by the two half molds 5 through the through hole on the hollow tube 6, thereby inflating the thermoplastic plastic to fit the shape of the inner wall of the mold, thereby realizing the molding of the UV glue bottle.

[0024] like Figure 2 As shown, rotating rods 1001 are symmetrically provided on both sides of the transverse portion of the inverted L-shaped plate 101. The end of one rotating rod 1001 is connected to the output shaft of the motor 10 installed on the inverted L-shaped plate 101. The two ends of the rotating rod 1001 are respectively installed with a first gear 603 and a second gear 1002, wherein the two second gears 1002 are meshed with each other, and the two first gears 603 are respectively meshed with the racks 601 installed on both sides of the hollow tube 6. When the motor 10 drives one rotating rod 1001 to rotate, the rotating rod 1001 drives the other rotating rod 1001 through the two second gears 1002 meshed with each other. 1 rotates, thereby driving the first gears 603 at the ends of the two rotating rods 1001 to rotate, and the two first gears 603 rotate in opposite directions, thereby driving the rack 601 to move up and down, thereby realizing the lifting and lowering movement of the hollow tube 6. When the hollow tube 6 descends, the molten thermoplastic plastic on the placement frame 2 is squeezed downward into the mold formed by the two half molds 5 through its lower end. The air is compressed by the first air pump 4 and passes through the telescopic hose 602 and the inner wall of the thermoplastic plastic of the hollow tube 6, thereby inflating the thermoplastic plastic and making it adhere to the inner wall of the mold, thereby realizing the molding of the UV glue bottle.

[0025] like Figure 4 As shown, a protrusion is provided on the circumferential outer wall of the lower part of the hollow tube 6, and a first sealing cover 604 is slidably connected to the hollow tube 6 for sealing the opening of the enclosed half mold 5. The first sealing cover 604 seals the top opening of the mold to prevent gas from flowing out of the top opening of the mold, thereby achieving the ability to inflate the thermoplastic plastic and make it fit the inner wall of the mold.

[0026] As shown in Figure 6, a second sealing cover 1101 is installed on both sides of the half mold 5, and a sealed cavity is provided between the outer wall of the half mold 5 and the second sealing cover 1101. The sealed cavity between the second sealing cover 1101 and the outer wall of the half mold 5 is connected to the inner cavity of the half mold 5 via a through hole opened on the half mold 5. The second air pump 9 installed on the U-shaped block 302 is connected to the sealed cavity via a connecting hose 1102.

[0027] like Figure 2 and Figure 3 As shown, a horizontal plate is provided at the air inlet hole opened on the half mold 5, and a first guide rod 701 is slidably provided on the horizontal plate. A spring 702 is provided between the end of the first guide rod 701 facing the outside of the half mold 5 and the horizontal plate. The spring 702 is wound on the first guide rod 701, and the end of the first guide rod 701 facing the inner cavity of the half mold 5 is connected to a baffle 7 for blocking the air inlet hole. When the spring 702 is in a normal state, the baffle 7 blocks the air inlet hole on the half mold 5.

[0028] During use, the thermoplastic plastic is first melted and then extruded into a square shape and placed on the placement rack 2. Subsequently, the motor 10 drives the connected rotating rod 1001 to rotate through the output shaft. The rotating rod 1001 drives the other rotating rod 1001 to rotate through the second gear 1002 that meshes with each other, and drives the rack 601 to move up and down through the first gear 603 on the two rotating rods 1001, thereby realizing the lifting and lowering movement of the hollow tube 6. When the motor 10 rotates forward, the hollow tube 6 moves downward and squeezes the melted thermoplastic plastic on the placement rack 2 downward, thereby placing the melted thermoplastic plastic between the molds formed by the two half molds 5. Then, compressed air is poured into the hollow tube 6 through the first air pump 4, and the compressed air is blown out through the through hole on the hollow tube 6, thereby inflating the thermoplastic plastic to fit the shape of the inner wall of the mold, thereby realizing the molding of the UV glue bottle, and through the motor 1 0 is reversed, so that the hollow tube 6 moves up and resets, providing convenience for the next blow molding; when the molded UV glue bottle is cooled, the two half molds 5 are separated by the contraction action of the piston rod of the cylinder 3. At the same time, the compressed air is input into the cavity formed by the second sealing cover 1101 and the half mold 5 through the connecting hose 1102 by the second air pump 9, and is input into the half mold 5 through the air inlet hole on the half mold 5. When the compressed air is poured into the half mold 5 through the air inlet hole, the compressed air impacts the baffle 7, causing the baffle 7 to move away from the inner wall of the half mold 5 and compress the spring 702, thereby releasing the baffle 7 from the blockage of the air inlet hole on the half mold 5, so that the compressed air can enter the half mold 5, thereby accelerating the separation of the outer wall of the molded UV glue bottle and the inner wall of the half mold 5, thereby realizing the demoulding operation of the molded UV glue bottle, so that the finished product UV glue bottle can be conveniently taken out.
