Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cooling box roto-molded parts, and in particular relates to a displacement mechanism of a shaping frame plate of a box roto-molded part. Background Art
[0002] Roto-molded box products are widely used in various applications in the manufacturing industry, such as logistics, transportation, and storage. Roto-molding technology holds an important position in the plastics manufacturing industry due to its low cost and strong adaptability. However, there are some technical difficulties in the cooling and shaping stage of roto-molded products. Traditional cooling and shaping methods rely on workers to control the amount of air blown into the box based on experience. This method often suffers from excessive or insufficient air blowing, causing the box to sag or bulge during the cooling process, which in turn affects the dimensional accuracy and quality of the product.
[0003] Although various molding machines are currently available on the market, many have limitations in adapting to the varying sizes and shapes of rotomolded products. Furthermore, there is room for improvement in ensuring molding accuracy and increasing production efficiency. Therefore, it is crucial to develop a molding frame displacement mechanism that can accommodate a variety of product sizes, improve molding accuracy, and enhance automation.
[0004] The traditional cooling shaping method has an unstable pass rate due to its strong subjectivity in operation. The traditional shaping method relies on manual control and cannot accurately control the displacement of the shaping frame, which makes it difficult to ensure the dimensional accuracy of the product and may cause problems such as product deformation or dents. Manual control of the shaping process requires operators to have certain skills and experience, and the operation process is labor-intensive and inefficient. Traditional shaping equipment usually lacks adaptability and is difficult to adjust to rotationally molded parts of different sizes and shapes, which limits production flexibility. Since the shaping process requires manual operation and there is a problem of inaccurate shaping, production efficiency is low and the production cycle is increased. Due to inaccurate shaping, products may be unqualified, increasing the scrap rate and the frequency of reprocessing, and increasing production costs.
[0005] In order to overcome the above-mentioned defects, a displacement mechanism of the forming frame plate of the box rotationally molded parts is proposed, which realizes precise control through a mechanical structure, thereby reducing product dimensional deviation and improving the overall qualification rate of the product. Utility Model Content
[0006] The present invention aims to solve the technical problem that the shaping method in the above-mentioned prior art relies on manual control and cannot accurately control the displacement of the shaping frame plate, resulting in difficulty in ensuring product dimensional accuracy and possible product deformation or dents.
[0007] To achieve the above objectives, the present invention provides the following technical solutions:
[0008] A displacement mechanism for a box body rotationally molded part forming frame, comprising a mounting frame, a rotating part and a guide rod.
[0009] On one side of the mounting frame, there are evenly arranged a number of telescopic cylinders that push the shaping frame to move. The telescopic cylinders push the shaping frame toward the outer side of the box rotomolded part, thereby limiting the position of the box rotomolded part during cooling and shaping.
[0010] The rotating member is used to connect the shaping frame plate and the telescopic cylinder. The shaping frame plate can be tilted by the rotating member, so that the shaping frame plate can fit the inclined surface of the box roto-molded part during shaping;
[0011] The guide rod is arranged on the shaping frame plate and assists in guiding when the shrinking cylinder pushes the shaping frame plate to move.
[0012] Preferably, the guide rods are located on both sides of each rotating member, and the guide rods are fixed below the rectangular plate fixedly arranged at the bottom of the forming frame plate.
[0013] Preferably, the rotating member comprises two vertical plates fixed to the bottom of the rectangular plate and forming a U-shaped opening, a support rod extending through the two vertical plates, and a connecting rod ball rod that rotatably fits over the outer sides of the support rods, is positioned within the U-shaped opening, and is fixedly connected to the end of the piston rod of the telescopic cylinder. The U-shaped opening formed by the two vertical plates allows the support rod to pass through, and the connecting rod ball rod rotatably fits over the outer sides of the support rods, allowing rotation. This allows the sizing frame plate to tilt to accommodate different product surface shapes.
[0014] Preferably, the fixed end of the telescopic cylinder is fixed on a mounting plate, the mounting plate is fixed between two square tubes, and the square tubes are fixed on the outer side of the mounting frame.
[0015] Preferably, a support plate is fixed on the mounting frame, and a through hole is provided on the support plate for the guide rod to be inserted. The through hole provided on the support plate allows the guide rod to be inserted accurately, thereby ensuring the stability of the shaping frame plate during movement.
[0016] Preferably, the bottom thread of the guide rod is sleeved with a limit nut which is limited on the outside of the support plate. The limit nut can provide a positioning limit for the guide rod to prevent the guide rod from excessively moving under the action of the telescopic cylinder.
[0017] Preferably, the shaping frame plate is evenly fixed with running wheels that move along the mounting frame when the telescopic cylinder moves the shaping frame plate. The running wheels help ensure the stability of the shaping frame plate during movement.
[0018] Compared with the prior art, the technical effects and advantages of the utility model are:
[0019] The displacement mechanism of the box rotomolding part shaping frame plate is composed of a mounting frame, rotating parts, and guide rods. The mounting frame is evenly arranged with telescopic cylinders, which are used to push the shaping frame plate to move outward from the box, achieving limiting positioning. The rotating parts allow the shaping frame plate to tilt to adapt to the inclined part of the box surface. The guide rods provide auxiliary guidance during the movement of the frame plate, ensuring stability and accuracy of movement. The fixed end of the telescopic cylinder is fixed on the mounting plate, which is fixed between the square tubes on the outside of the mounting frame, increasing the strength and rigidity of the device. The shaping frame plate is evenly fixed with walking wheels, reducing friction and noise during movement, and improving movement accuracy and stability.
[0020] The design achieves more accurate control through mechanical structure, avoids the concave and deformation of the box during the cooling process, ensures that the product size meets the requirements, and improves the product qualification rate. At the same time, the automation or semi-automation of the shaping process reduces the complexity of worker operation, improves production efficiency. In addition, the design can be adjusted according to the size of different products, has strong applicability, and reduces waste products and reprocessing due to unqualified products, thereby saving production cost.
[0021] The guide rods are located on both sides of each rotating part, increasing the stability of the entire structure. The guide rods are fixed below the rectangular plate at the bottom of the shaping frame plate, providing precise guidance for the movement of the frame plate, ensuring the stability of the frame plate during movement. The limiting nut is fixed outside the support plate, which can provide positioning limit for the guide rod, prevent the guide rod from moving excessively under the action of the telescopic cylinder, and ensure the displacement accuracy of the shaping frame plate. The limiting nut can be easily adjusted to adapt to rotomolding parts of different sizes, increasing the application range of the tooling. The limiting nut can also prevent the guide rod from being damaged when subjected to excessive force, protecting the integrity of the guide mechanism and the entire tooling.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0030] The drawings will be described below Figure 1-6 The application will be further described in detail,
[0031] The embodiment of the application discloses a displacement mechanism of a box body rotational molding part shaping frame plate, which comprises a mounting frame 1, a rotating part 4 and a guide rod 5,
[0032] A plurality of telescopic cylinders 3 for pushing the displacement of the shaping frame plate 2 are arranged on the mounting frame 1 in alignment with one side of the shaping frame plate 2, the telescopic cylinders 3 push the shaping frame plate 2 to displace towards the outer side of the box body rotational molding part 13, and then limit and position the box body rotational molding part 13 during the cooling and shaping of the box body rotational molding part 13.
[0033] Walking wheels 12 for walking along the mounting frame 1 during the displacement of the shaping frame plate 2 pushed by the telescopic cylinders 3 are fixed on the shaping frame plate 2. The design of the walking wheels 12 makes the friction smaller when the shaping frame plate 2 moves along the mounting frame 1 pushed by the telescopic cylinders 3, thereby reducing the energy consumption and the noise. The walking wheels 12 help to ensure the stability of the shaping frame plate 2 during the movement and improve the movement accuracy. The walking wheels 12 reduce the direct contact with the mounting frame 1 and reduce the wear, thereby prolonging the service life of the tooling. Since the walking wheels 12 reduce the friction, the maintenance frequency and cost are also reduced accordingly.
[0034] The fixed end of the telescopic cylinder 3 is fixed on the mounting plate 7, the mounting plate 7 is fixed between two square tubes 8, and the square tubes 8 are fixed on the outer side of the mounting frame 1. The fixed end of the telescopic cylinder 3 is fixed on the mounting plate 7, which can disperse the force generated during the operation of the cylinder and reduce the pressure on a single fixing point. The mounting plate 7 is fixed between two square tubes 8, and the square tubes 8 are fixed on the outer side of the mounting frame 1. This structure design increases the strength and rigidity of the whole device. Through the design of the square tubes 8 and the mounting plate 7, the mounting frame 1 can be effectively protected from being directly affected by the action of the cylinder, thereby prolonging the service life of the equipment.
[0035] The rotating member 4 is used to connect the shaping frame 2 and the telescopic cylinder 3. The shaping frame 2 can be tilted by the rotating member 4. During the shaping of the box roto-molded part 13, the shaping frame 2 can fit the inclined surface of the box roto-molded part 13.
[0036] The rotating member 4 comprises two vertical plates 42 fixed to the bottom of the rectangular plate 6 and forming a U-shaped opening 41, a support rod 43 extending through the two vertical plates 42, and a connecting rod ball 44 that rotatably fits over the outer side of the support rods 43, lies within the U-shaped opening 41, and is fixedly connected to the piston rod end of the telescopic cylinder 3. The U-shaped opening 41 formed by the two vertical plates 42 allows the support rod 43 to pass through. The connecting rod ball 44 rotatably fits over the outer side of the support rod 43, allowing rotation. This allows the sizing frame 2 to tilt to accommodate various product surface shapes, increasing the adaptability of the tooling. The connecting rod ball 44 rotatably fits over the outer side of the support rod 43 and is fixedly connected to the piston rod end of the telescopic cylinder 3, enhancing the stability and reliability of the connection. This structural design facilitates maintenance and component replacement.
[0037] The guide rod 5 is arranged on the shaping frame plate and assists in guiding when the shrinking cylinder pushes the shaping frame plate 2 to move.
[0038] Guide rods 5 are located on either side of each rotating member 4 and are fixed beneath a rectangular plate 6 fixed to the bottom of the sizing frame 2. The guide rods 5 on either side of the rotating member 4 prevent lateral movement of the sizing frame 2 when the cylinder pushes it, thus increasing the stability of the entire structure. The guide rods 5, fixed beneath the rectangular plate 6 at the bottom of the sizing frame 2, provide precise guidance for the movement of the sizing frame 2 and ensure its stability during movement.
[0039] A support plate 9 is fixed to the mounting frame 1. This plate has holes 10 for the guide rods 5. These holes 10 allow the guide rods 5 to be inserted and fixed precisely, ensuring the stability of the sizing frame 2 during movement and preventing deviation and shaking. The presence of the support plate 9 provides additional support for the entire fixture, enhancing its structural stability.
[0040] The bottom of the guide rod 5 is threadedly engaged with a limit nut 11, which is fixed to the outside of the support plate 9. This limit nut 11, fixed to the outside of the support plate 9, provides a fixed position for the guide rod 5, preventing excessive movement of the guide rod 5 under the action of the telescopic cylinder 3 and ensuring the displacement accuracy of the forming frame 2. The limit nut 11 can be easily adjusted to accommodate rotationally molded parts of different sizes, expanding the applicability of the tooling. The limit nut 11 also prevents damage to the guide rod 5 when subjected to excessive force, protecting the integrity of the guide mechanism and the entire tooling.
[0041] The displacement mechanism for the rotomolded box 13 features sizing plates 2 mounted on the two larger sides of the rotomolded box 13. These plates are connected to the mounting frame 1 via telescopic cylinders 3. After the rotomolded box is removed from the rotomolding machine, an air compressor is used to pump air into the interior, and then the telescopic cylinders 3 are activated. The telescopic movement of the telescopic cylinders 3 propels the sizing plates 2 toward the outer sides of the rotomolded box 13.
[0042] The design of the rotating member 4 allows the shaping frame 2 to tilt, which can better adapt to the possible tilted portion of the surface of the box rotationally molded part 13, so that the frame can fit more closely to the product surface. During the movement of the frame, the guide rod 5 provides auxiliary guidance to ensure the stability and accuracy of the frame during movement.
[0043] By precisely controlling the displacement of the shaping frame plate 2, dents and deformation of the box during the cooling process are avoided, ensuring that product dimensions meet requirements and improving product qualification rates. Traditional empirical methods for controlling the air volume are prone to errors, while this design achieves more precise control through mechanical structures. Automating or semi-automating the shaping process reduces operator complexity and improves production efficiency. This design can be adjusted to suit different product sizes, offering high adaptability. This reduces waste and reprocessing due to substandard products, thereby saving production costs.
[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
