Description

Technical Field

[0001] The utility model relates to the technical field of demoulding structures, in particular to an anti-deformation demoulding structure. Background Art

[0002] When packaging foods such as nuts, candies, and cakes, plastic cans are used for the convenience of transportation and storage. When processing plastic tubes, most of them are injection molded by injection molds. In order to facilitate the removal of the product after molding, a demolding structure is generally used to demold the molded product. For example, the patent with application number 202023163402.3 proposes a quick demolding structure for an injection mold, including a fixed frame, and four support columns of the same size are slidably installed on the rectangular inner wall of the fixed frame, and the right side of each support column is detachably connected to the left side wall of the mounting seat, and a fixed module is detachably installed on the right side of the mounting seat, and four springs of the same model are detachably installed on the rectangular right side wall of the fixed frame, a vibration motor is detachably installed in the middle of the right side wall of the fixed frame, and a spiral tube is detachably installed in the middle of the left side wall of the mounting seat. The above scheme combines the fixed module with the movable mold and the injection material and forms it in the fixed module. After the movable mold is removed, the molded workpiece is located inside the fixed module. The coolant in the coolant tank is pumped into the spiral tube by a pump, which can cool the fixed module, which is beneficial to the rapid cooling and molding of the molded workpiece. In combination with the vibration of the vibration motor, the molded workpiece inside the fixed module can be quickly shaken off.

[0003] During the demoulding process of the existing plastic jar injection molding mold, the jar body is not stable enough and is prone to deformation, which in turn affects the normal use of the plastic jar and increases the production cost. Therefore, we have made improvements to this and proposed an anti-deformation demoulding structure. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 , Figure 2 As shown, an anti-deformation demoulding structure includes a workbench 1, a mold 2 is arranged on the upper surface of the workbench 1, side panels 3 are installed on both sides of the upper surface of the workbench 1, a top plate 4 is movably installed between the two side panels 3, a driving mechanism 5 for controlling the movement of the top plate 4 is arranged inside the side panels 3, and a demoulding mechanism 6 is arranged inside the top plate 4.

[0023] like Figure 3 As shown, a groove 301 is provided on one side surface of each side panel 3, and the driving mechanism 5 includes a first driving motor 501, which is installed on the top of one of the side panels 3, and an adjusting screw rod 502 is installed at the output end of the first driving motor 501, one end of the adjusting screw rod 502 is rotatably set on the bottom inner wall of the groove 301 at the corresponding position, and a first screw rod sleeve 503 is movably installed on the rod body of the adjusting screw rod 502, and a limiting rod 504 is installed inside the groove 301 away from the adjusting screw rod 502, and a sliding sleeve 505 is slidably installed on the rod body of the limiting rod 504, and one end of the sliding sleeve 505 and the first screw rod sleeve 503 are respectively fixedly installed on the two end surfaces of the top plate 4.

[0024] By adjusting the meshing transmission between the screw rod 502 and the first screw rod sleeve 503, the top plate 4 can be controlled to move up and down under the drive of the first drive motor 501, so as to adjust the position of the arc support plate 605, so as to facilitate the demoulding of the plastic can.

[0025] like Figure 3 , Figure 4 As shown, the demoulding mechanism 6 includes a through slot 601 and a second drive motor 602. The through slot 601 is opened on both sides of the upper surface of the top plate 4. The second drive motor 602 is installed on one side of the inside of the top plate 4. A bidirectional screw rod 603 is installed at the output end of the second drive motor 602. One end of the bidirectional screw rod 603 is rotatably set on the inner wall of one end of the through slot 601. Second screw rod sleeves 604 are movably installed on the rod body of both sides of the bidirectional screw rod 603. Each second screw rod sleeve 604 is slidably set inside the through slot 601 at a corresponding position. An arc-shaped support plate 605 is installed at the bottom of each second screw rod sleeve 604. A mounting groove 606 is opened on one side surface of each arc-shaped support plate 605. Connecting springs 607 are installed on both sides of the inner wall of one end of each mounting groove 606. An arc-shaped limiting plate 608 is installed at one end of the connecting spring 607. One end of the arc-shaped limiting plate 608 is slidably set inside the mounting groove 606.

[0026] Through the meshing transmission between the bidirectional screw rod 603 and the second screw rod sleeve 604, under the drive of the second drive motor 602, the two arc support plates 605 can be controlled to move in opposite directions, so that the arc support plates 605 can clamp the inside of the plastic can, which is convenient for demoulding. The arc limit plate 608 is movably installed by connecting the spring 607. During the movement of the arc support plate 605, the arc limit plate 608 will first contact the inner wall of the plastic can. Under the elastic action of the spring, the arc limit plate 608 can protect the can body and avoid damage to the plastic can caused by the large movement distance of the arc support plate 605.

[0027] The working principle of this anti-deformation demoulding structure:

[0028] When in use, the mold 2 to be demoulded is placed on the surface of the workbench 1, and the first driving motor 501 is driven to control the adjustment screw rod 502 to rotate. Under the meshing action between the adjustment screw rod 502 and the first screw rod sleeve 503, the first screw rod sleeve 503 can drive the top plate 4 to move up and down, and control the arc support plate 605 to move to the inside of the tank body in the mold 2. The second driving motor 602 drives the bidirectional screw rod 603 to rotate. Under the meshing action between the bidirectional screw rod 603 and the second screw rod sleeve 604, the two second screw rod sleeves 604 can drive the arc support plates 605 to move in opposite directions, and the two arc support plates 605 can be moved. 05 is adjusted to the inner walls on both sides of the tank body, which can not only support the inside of the tank body so that the tank body will not be deformed during the demoulding process, but also clamp the tank body to facilitate demoulding. By driving the first drive motor 501, the plastic tank clamped by the arc-shaped support plate 605 can be controlled to move up and down, thereby completing the demoulding of the plastic tank. An arc-shaped limiting plate 608 is movably installed on one side of the arc-shaped support plate 605 through a connecting spring 607, so that the arc-shaped limiting plate 608 still has a certain distance of moving space after contacting the inner wall of the tank body, which can avoid the arc-shaped support plate 605 from squeezing the tank body due to a large moving distance, and can play a role in protecting the tank body.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
