Description

Technical Field

[0001] This utility model belongs to the field of pontoon processing technology, and relates to a blow molding mold for long pins used in connecting double-layer pontoons. Background Technology

[0002] The pontoons are manufactured using a blow molding process and can float on the water. They are made of strong and tough high-molecular-weight polyethylene and other materials, which have good weather resistance and impact resistance. They are also resistant to ultraviolet rays, freezing, and corrosion from seawater chemicals and oil stains. They can automatically rise and fall with the tides and are widely used in the construction of floating platforms such as floating bridges and floating docks. The long pin structure used for connecting the pontoons is also processed using blow molding molds.

[0003] In existing blow molding molds, the internal cavities are fixed. After the long pin structure is blow molded, it can directly detach from the cavity on its own. This demolding structure is slow, and when there is a lot of friction between the long pin structure and the inside of the cavity, it is difficult for it to detach on its own. It needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a blow molding mold for a long pin for connecting double-layer floats, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: a blow molding mold for connecting double-layer floats with long inserts, including a mounting plate and a mold base. The mold base is mounted on the outer side of the mounting plate. A lower cavity is formed inside the mold base. An upper push plate is movably arranged at the top of the lower cavity. An upper cavity is formed inside the upper push plate. A primary push seat is arranged inside the primary push seat. A supporting inner plate is movably arranged inside the primary push seat. A secondary push seat is arranged at the middle position of the supporting inner plate. The secondary push seat is placed inside the primary push seat. Ejector pins are provided at both ends of the supporting inner plate. A side bracket is provided on the side of the primary push seat. A clamping plate is movably arranged on the side of the side bracket. A limit claw is provided at the front end of the side bracket.

[0006] In the above-mentioned blow molding mold for connecting double-layer floats with long pins, the mold base has an inner groove, and a pusher plate is movably arranged inside the inner groove. The surface of the pusher plate is connected to the first-stage pusher seat through a push rod.

[0007] In the above-mentioned blow molding mold for connecting double-layer floats with long pins, a cylinder is provided in the middle of the inner groove. The output end of the cylinder is connected to one side of the pusher plate. A cylinder is installed in the middle of the pusher plate. The output end of the cylinder is connected to one side of the middle of the supporting inner plate.

[0008] In the above-mentioned blow molding mold for connecting double-layer floats with long pins, an inner slide plate is movably arranged inside the side bracket, the limiting claw is connected to the end position of the inner slide plate, and the clamping plate is arranged on one side of the inner slide plate.

[0009] In the aforementioned blow molding mold for connecting double-layer floats, a side cylinder is installed inside the side bracket, and the output end of the side cylinder is connected to one side of the inner slide plate.

[0010] In the above-mentioned blow molding mold for connecting double-layer floats, a guide rod is provided on the side of the mounting plate, and one end of the two ejector pins is placed in the upper cavity and the lower cavity, respectively.

[0011] Compared with the prior art, the advantages of the long pin blow molding mold for connecting double-layer floats of this utility model are:

[0012] This application sets up a primary ejector seat and a secondary ejector seat inside the mold base. The primary ejector seat has side supports on both sides. After the workpiece inside the mold base is blow-molded, the mold base opens. The primary ejector seat can move outward by the push plate, thereby ejecting part of the blow-molded part out of the cavity. At the same time, the blow-molded part can be limited by the clamping plate and the limiting claw, which facilitates the tearing of waste material at the top and bottom of the blow-molded part. After the blow-molded part is processed, the limiting support of the blow-molded part is released. Then, the secondary ejector seat plate inside the primary ejector seat, together with the ejector pin, ejects the blow-molded part again, so that the blow-molded part is completely pushed out of the cavity and the primary ejector seat, completing the unloading of the blow-molded part.

A secondary push seat 15 is set in the middle of the supporting inner plate 16 and is placed inside the primary push seat 7. Ejector pins 17 are set at both ends of the supporting inner plate 16. A side bracket 10 is set on the side of the primary push seat 7. A clamping plate 12 is movably mounted on the side of the side bracket 10. A limit claw 11 is set at the front end of the side bracket 10.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a blow molding mold for connecting double-layer floats with long pins. Specifically, the mold base 2 has an inner groove, and a pusher plate 6 is movably arranged inside the inner groove. The surface of the pusher plate 6 is connected to the first-stage pusher seat 7 through a push rod.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a blow molding mold for connecting double-layer floats with long inserts. Specifically, a cylinder 8 is provided in the middle of the inner groove. The output end of the cylinder 8 is connected to one side of the pusher plate 6. A cylinder 9 is installed in the middle of the pusher plate 6. The output end of the cylinder 9 is connected to one side of the middle of the supporting inner plate 16. The cylinders 8 and 9 are commercially available devices known to those skilled in the art. Here, we are only using them without making any structural or functional improvements, and we will not elaborate further.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a blow molding mold for connecting double-layer floats with long pins. Specifically, an inner slide plate 13 is movably arranged inside the side support 10, a limiting claw 11 is connected to the end position of the inner slide plate 13, a pressure plate 12 is arranged on one side of the inner slide plate 13, the pressure plate 12 presses and limits the injection molded part, and the limiting claw 11 limits the injection molding machine.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the long pin blow molding mold for connecting the double-layer float of this utility model is specifically designed so that a side cylinder 14 is installed inside the side bracket 10. The output end of the side cylinder 14 is connected to one side of the inner slide plate 13. The side cylinder 14 pushes the inner slide plate 13 to move. The side cylinder 14 is a device known to those skilled in the art that can be directly purchased from the market. Here we are just using it without making any structural or functional improvements. We will not go into details here.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a blow molding mold for connecting double-layer floats. Specifically, a guide rod is provided on the side of the mounting plate 1, and one end of the two ejector pins 17 are respectively placed in the upper cavity 4 and the lower cavity 5. The guide rod mainly guides and supports the mounting plate 1 when it moves, and the mounting plate 1 is pushed by an external cylinder when it moves, thereby completing the mold closing of the mold base 2.

[0025] This utility model relates to a blow molding mold for connecting double-layer floats with long pins. The mold base 2 of this application has two molds, left and right, each with the same cavity structure. When the two mold bases 2 are closed, they are pushed together by an external cylinder. Blow molding is then performed inside the closed cavity. After the internal workpiece of the mold base 2 is blow-molded, the mold base 2 opens, and simultaneously the upper push plate 3 slides upward, causing the upper cavity 4 inside the upper push plate 3 to separate from the upper part of the blow-molded part. The upper push plate 3 can be moved by an electric push rod. After the upper push plate 3 moves away, cylinder 8 pushes the pusher plate 6 to move. The first-stage pusher seat 7 can move outwards through the pusher plate 6, thereby... The primary ejector 7 ejects part of the blow-molded part from the cavity. At the same time, when the inner slide plate 13 moves, it can drive the clamping plate 12 and the limiting claw 11 to move. The clamping plate 12 and the limiting claw 11 can also limit the blow-molded part, making it easier for the operator to tear off the waste material at the top and bottom of the blow-molded part. After the blow-molded part is processed, the inner slide plate 13 retracts, driving the clamping plate 12 and the limiting claw 11 to move away, releasing the limiting support on the blow-molded part. Then, the secondary ejector 15 inside the primary ejector 7, together with the ejector pin 17, ejects the blow-molded part again, so that the blow-molded part is completely pushed out from the cavity and the primary ejector 7, thus completing the unloading of the blow-molded part.
