Description

Technical Field

[0001] The utility model relates to a support rod for an egg roll table and a processing mold, belonging to the technical field of processing the support rod of the egg roll table. Background Art

[0002] The egg roll table is a portable folding table for outdoor use. It is easy to store and practical. It is called an egg roll table because its table top looks like an egg roll after being stored. Generally speaking, the egg roll table is stable and flat, hard and wear-resistant, and the folding design makes the egg roll table easy to store and easy to travel.

[0003] In the market, the egg roll tables used on the beach are usually made of wood (including the tabletop and support rods). From the perspective of environmental protection, wooden support rods require a lot of wood raw materials, high requirements, and large resource consumption. From the perspective of long-term development, it is not conducive to the protection of forest resources. In addition, the support rods of the beach egg roll table are used outdoors for a long time on the beach, seaside, etc., and the use environment is easy to absorb moisture and be easily infested by pests. Through market research, aluminum alloy tubular profiles are used to replace the wooden support rods of the beach egg roll table to meet actual use needs and play a role in moisture-proof and preventing pests from infesting.

[0004] However, in the prior art, there is no special mold for producing the new support rod. The mold for producing ordinary aluminum alloy tubular profiles has a single chamber (i.e., a single-channel extrusion chamber) during the extrusion process, which makes it easy for the aluminum profile to stick to the extrusion chamber, causing the aluminum profile to accumulate at the front end of the extrusion chamber, thereby causing the extrusion chamber to be blocked. When the single-channel extrusion chamber is blocked, it cannot work normally and needs to be cleaned before it can continue to work, affecting normal production. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to provide a support rod processing mold for an egg roll table, which is a production mold for the aluminum alloy tubular profile support rod, and is provided with a grid channel and a three-channel extrusion chamber. On the one hand, the grid channel can divide the thicker aluminum profile into small pieces of aluminum profile to avoid the extrusion chamber from being blocked. On the other hand, the three-channel extrusion chamber has a redundant function. When one of the extrusion chambers is blocked, the other two can still work normally, thereby improving work efficiency.

[0006] Another technical problem to be solved by the utility model is to utilize the above processing mold to manufacture and process a new support rod for an egg roll table, thereby improving the problem that the support rod of the existing egg roll table is easily affected by moisture and damaged by insects.

[0007] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0008] A supporting rod processing mold for an egg roll table, comprising:

[0009] The upper die is provided with three grid channels along the circumference of the center position for extruding and cutting the aluminum profile;

[0010] The lower die is provided with three extrusion chambers along the circumference of the center position for extruding and forming an aluminum support rod component, the cross section of which is a rectangular structure.

[0011] Since the cross section of the aluminum alloy tubular profile used for the beach egg roll table support rod produced by this mold is a rectangular structure, the cross section of the extruded aluminum support rod component is a rectangular structure. This mold uses three grid channels to extrude and divide the original aluminum profile into three thinner aluminum profiles, which then enter the extrusion chamber respectively, and finally undergo secondary extrusion to form a rectangular aluminum alloy tubular profile, which is then sheared by a shearing machine to form a support member of the beach egg roll table of the required size. The support member of the aluminum alloy tubular profile can prevent insect damage and moisture.

[0012] Finally, a punching machine can be used to remove the middle part of the rectangular aluminum alloy tubular profile, and the rectangular aluminum alloy tubular profile can be hollowed out to achieve the overall material weight reduction requirement, thereby reducing the weight of the support rod used for the beach roll table and providing convenience for transportation.

[0013] Preferably, the gate channels are distributed at equal intervals, and each gate channel includes a plurality of gate cavities.

[0014] During the extrusion process, the large and thick rectangular aluminum alloy tubular profile needs to be pressed directly into the grid cavity through a press. The grid cavity can decompose the original aluminum alloy tubular profile into several small aluminum alloy tubular profiles, providing convenience for subsequent extrusion into the extrusion chamber.

[0015] Preferably, the sub-grid cavities are distributed at equal intervals along the circumference of the central axis of the sub-grid channel.

[0016] The equally spaced distribution can evenly extrude and split the aluminum alloy tubular profile, thereby ensuring that the final support rod is made of uniform material and that each position is subjected to uniform force, thus ensuring that the egg roll table can be placed stably on the beach.

[0017] Preferably, the split-gate cavity is an equilateral triangle structure, and each corner is provided with a rounded transition section.

[0018] The triangular structure, on the one hand, facilitates the subsequent profile to pass through the extrusion chamber smoothly, and on the other hand, its edges are convenient for extrusion and cutting, while the rounded corners can avoid the uneven distribution of the profile caused by the corner materials gathering to the center of the profile during the corner extrusion.

[0019] Preferably, a positioning piece is provided on one end of each of the grid channels facing the aluminum profile input direction.

[0020] The positioning piece can hold the center of the profile during the extrusion process to prevent the profile from shifting.

[0021] Preferably, a guide frame is fixedly connected to one end of the upper mold facing the input direction of the aluminum profile, and the guide frame is wrapped around the three grid channels to provide input guidance for the aluminum profile.

[0022] The rectangular original profile can be directly squeezed into the guide frame by the press, and then directly squeezed into the grid channel. The frame of the guide frame can provide fixed support and directional guidance for the original profile, allowing the original profile to smoothly enter the grid channel while effectively preventing the original profile from deflecting.

[0023] Preferably, the three extrusion chambers are distributed at equal intervals, and each extrusion chamber is a rectangular structure, and each rectangle has rounded corners.

[0024] The triangular profile with rounded corners will be extruded into a rectangular rod after passing through a rectangular extrusion chamber with rounded corners, and then cut to obtain the required support rod of the egg roll table made of rectangular aluminum alloy with rounded corners.

[0025] Preferably, an end of the lower die facing the aluminum profile input direction is provided with an accommodating cavity at a position corresponding to the guide frame, for accommodating the guide frame.

[0026] Preferably, a plurality of plug holes are distributed in the circumferential direction of the upper die and the lower die for plugging the pin shaft and connecting the upper die and the lower die.

[0027] The pin shaft and the plug hole are used for interference fit to realize the effective connection between the upper die and the lower die, so that the upper die and the lower die can be transported or transferred together.

[0028] A support rod for an egg roll table, wherein the cross section of the support rod is a rectangular structure with rounded corners, and the support rod is manufactured using the processing mold described above.

[0029] The processing mold is used to manufacture and process a new support rod for an egg roll table, thereby improving the problem that the support rod of the existing egg roll table is easily affected by moisture and damaged by insects.

[0030] The beneficial effects of the utility model are:

[0031] (1) The utility model provides a new support rod for an egg roll table, which can replace the support rod of an existing wooden egg roll table, thereby preventing the support rod from being easily affected by moisture and being corroded by insects.

[0032] (2) Through the utility model, a mold for producing a new type of egg roll support rod is provided, which is provided with a grid channel and a three-channel extrusion chamber. On the one hand, the grid channel can divide the thicker aluminum profile into small pieces of aluminum profile to avoid the extrusion chamber from being blocked. On the other hand, the three-channel extrusion chamber has a redundant function. When one of the extrusion chambers is blocked, the other two can still work normally, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0040] Example

[0041] In the market, the egg roll tables used on the beach are usually made of wood (including the tabletop and support rods). From the perspective of environmental protection, wooden support rods require a lot of wood raw materials, high requirements, and large resource consumption. From the perspective of long-term development, it is not conducive to the protection of forest resources. In addition, the support rods of the beach egg roll table are used outdoors for a long time on the beach, seaside, etc., and the use environment is easy to absorb moisture and be easily infested by pests. Through market research, aluminum alloy tubular profiles are used to replace the wooden support rods of the beach egg roll table to meet actual use needs and play a role in moisture-proof and preventing pests from infesting.

[0042] To this end, this embodiment provides a new support rod for an egg roll table used in a beach environment, referring to Figure 3As shown, the support rod 7 is formed by extrusion of aluminum alloy profile, and the cross section is a rectangular structure, and the corners are rounded to avoid scratching the body during manual handling. The aluminum alloy material itself has the characteristics of light weight and corrosion resistance, so it has the advantages of moisture-proof, pest-proof and easy to carry.

[0043] refer to Figure 4 The support rod 8 shown in the figure can further reduce the weight of the aluminum alloy profile, that is, make the beach egg roll table support rod lighter during transportation, by directly punching the rectangular aluminum alloy profile with a press to form an aluminum alloy profile with a hollow cross-section.

[0044] Since there is no special mold for producing the new support rod in the prior art, and the mold for producing ordinary aluminum alloy tubular profiles has a single chamber (i.e., a single-channel extrusion chamber) during the extrusion process, it is easy for the aluminum profile to stick to the extrusion chamber, causing the aluminum profile to accumulate at the front end of the extrusion chamber, resulting in blockage of the extrusion chamber. When the single-channel extrusion chamber is blocked, it cannot work normally and needs to be cleaned before it can continue to work, affecting normal production.

[0045] To this end, this embodiment provides a processing mold for producing an aluminum alloy profile for use in a support rod of a beach egg roll table, such as Figure 1-Figure 2 As shown, the processing mold includes: an upper mold 1 and a lower mold 2. Among them, the upper mold 1 is provided with three grid channels 11 at equal intervals along the circumference of the center position, which are used for extruding and cutting aluminum profiles. Each grid channel 11 includes four grid cavities 111 distributed at equal intervals along the circumference of the central axis of the grid channel 11. During the extrusion process, it is necessary to first press the large and thick rectangular aluminum alloy tubular profile directly to the grid cavity 111 through a press. The grid cavity 111 can decompose the original aluminum alloy tubular profile into four small aluminum alloy tubular profiles, which facilitates the subsequent extrusion into the extrusion chamber 21. The equal-spaced distribution of the three grid channels 11 and the four grid cavities 111 can evenly extrude and divide the aluminum alloy tubular profile, thereby ensuring that the material of the final formed support rod is uniform and the force at each position is uniform, thereby ensuring that the final egg roll table can be stably placed on the beach. Among them, a single grid cavity 111 is a regular triangle structure, and each corner is provided with a rounded transition section. The triangular structure, on the one hand, facilitates the subsequent profile to pass through the extrusion chamber 21 smoothly, and on the other hand, its edges are convenient for extrusion cutting, while the rounded corners can avoid the uneven distribution of the profile caused by the corner materials gathering to the center of the profile during the edge extrusion.

[0046] The lower die 2 has three extrusion chambers 21 distributed at equal intervals along the circumference of the center position, which are used for extruding and forming an aluminum support rod component. The cross section of the aluminum support rod component is a rectangular structure.

[0047] In some embodiments, referring to Figure 1 , at one end of each sub-grid channel 11 facing the input direction of the aluminum profile, a positioning member 3 is fixedly connected (this fixed connection method is a direct welding connection). The positioning member 3 can顶住 the center of the profile during the extrusion process to prevent the profile from shifting.

[0048] In some embodiments, a guiding frame 4 is welded to one end of the upper die 1 facing the input direction of the aluminum profile. The guiding frame 4 wraps around the three sub-grid channels 11 to provide input guidance for the aluminum profile. The rectangular original profile can be directly extruded into the guiding frame 4 by a press and then directly into the sub-grid channels 11. The frame of the guiding frame 4 can provide fixed support and direction guidance for the original profile, enabling the original profile to smoothly enter the sub-grid channels 11 while effectively preventing the original profile from shifting. At one end of the lower die 2 facing the input direction of the aluminum profile, a receiving cavity 5 corresponding to the position of the guiding frame 4 is provided for receiving the guiding frame 4.

[0049] In some embodiments, a number of insertion holes 6 are distributed in the circumferential direction of the upper die 1 and the lower die 2 for inserting pin shafts to connect the upper die 1 and the lower die 2. The pin shaft and the insertion hole 6 are used for interference fit to achieve effective connection of the upper die 1 and the lower die 2, facilitating the transportation or transfer of the upper die 1 and the lower die 2 together.

[0050] In some embodiments, referring to Figure 5 , the extrusion chamber 21 presents a "pin" - shaped structure. When the aluminum profile passes through the three extrusion chambers 21, the direction is the same, effectively avoiding the accumulation of the aluminum profile in the extrusion chamber 21 and reducing the pushing burden.

[0051] Since the cross - section of the aluminum alloy tubular profile used for the support rod of the beach egg roll table produced by this mold is a rectangular structure, the cross - section of the extruded aluminum support rod member is a rectangular structure. This mold uses three sub - grid channels 11 to extrude and divide the original aluminum profile into three thinner aluminum profiles, which then enter the extrusion chamber 21 respectively. Finally, it is secondarily extruded into an aluminum alloy tubular profile with a rectangular structure. Then, a shearing machine is used to shear the aluminum alloy tubular profile to form a support member of the beach egg roll table with the required size. The support member of the aluminum alloy tubular profile can prevent being蛀蚀 by pests and can also prevent moisture.

[0052] Finally, the middle part of the aluminum alloy tubular profile with a rectangular structure can be removed by a punching machine to make the aluminum alloy tubular profile with a rectangular structure hollow, meeting the weight reduction requirement of the overall material, thereby reducing the weight of the support rod applied to the beach egg roll table and facilitating handling.
