Description

Technical Field

[0001] The utility model relates to the technical field of lens production molds, in particular to a mold capable of producing multiple lenses. Background Art

[0002] A mold is a tool or equipment used to manufacture various products. It can be made of metal, plastic or other materials. Products of the same shape and size can be produced through the mold. The mold plays a very important role in industrial production.

[0003] In the existing lens production molds, the size and depth of the molds are fixed when producing lenses, and the lenses produced are also of fixed thickness. However, according to actual production needs, it is necessary to produce a variety of lenses with different thicknesses. In order to meet the needs, it is necessary to prepare multiple molds, which will consume a lot of costs to purchase or produce different molds. The cost is high, and when producing different lenses, it is also necessary to transfer between different molds, which will reduce production efficiency and affect production progress.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a mold capable of producing multiple lenses is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a mold capable of producing a variety of lenses, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold that can produce a variety of lenses, including a base, a lower mold base is fixedly installed on the upper surface of the base, a lower mold is slidingly provided on the upper side of the inner surface of the lower mold base, a two-way screw is rotatably provided on the lower side of the inner surface of the lower mold base, a drive motor is installed on the right end of the two-way screw passing through the lower mold base, pushing blocks are threadedly connected on the left and right sides of the surface of the two-way screw, a movable rod is rotatably provided on the upper surface of the push block, and the upper end of the movable rod is rotatably connected to the lower mold through the same shaft seat.

[0007] Preferably, cylinders are fixedly mounted on the inner walls of the four corners of the base, and the same upper die seat is fixedly mounted on the upper end of the cylinder.

[0008] Preferably, an upper mold is fixedly mounted on the middle portion of the lower surface of the upper mold base, and the shapes of the upper mold match those of the lower mold.

[0009] Preferably, a convergence groove is provided at the middle of the left and right sides of the upper surface of the base, and a spring is fixedly installed below the inner surface of the convergence groove.

[0010] Preferably, baffles are fixedly mounted on the left and right sides of the lower surface of the upper mold base, and the lower ends of the baffles are slidably arranged inside the convergence groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model is provided with a bidirectional screw, a drive motor, a push block and a movable rod. The drive motor drives the bidirectional screw to rotate. At this time, the push block is affected by the thread and moves in the opposite direction. The movable rod is used to lift the lower mold upward, changing the distance between the lower mold and the upper surface of the lower mold base. The position of the lower mold can be changed according to the requirements of different lens thicknesses. There is no need to replace or prepare different mold bodies to produce a variety of lenses with different thicknesses. It is more flexible and efficient to use and also reduces the procurement cost of the equipment. After molding, it can continue to move upward and protrude from the lower mold base, making it easier to manually demold the molded lens.

[0013] 2. The utility model is provided with a baffle, a convergence groove and a spring. When the mold is closed, the baffle is inserted into the convergence groove to form a barrier on both sides of the mold body, which can prevent the liquid inside the equipment from splashing out during mold closing and causing harm to surrounding personnel, thereby improving the safety protection of personnel when using the equipment. The spring provides a reverse thrust to the upper mold base through the baffle when pressing down, making the force of the upper mold base moving downward more linear, avoiding damage to the mold body itself caused by the instantaneous pressure generated by mold closing, improving the protection of the equipment itself, extending its service life, and effectively protecting both personnel and the equipment itself.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 3As shown, a mold for producing a variety of lenses includes a base 1, a lower mold base 2 is fixedly installed on the upper surface of the base 1, a lower mold 3 is slidingly provided on the upper side of the inner surface of the lower mold base 2, a two-way screw 4 is rotatably provided on the lower side of the inner surface of the lower mold base 2, the right end of the two-way screw 4 passes through the lower mold base 2 and is equipped with a drive motor 5, the left and right sides of the surface of the two-way screw 4 are threadedly connected with push blocks 6, the upper surface of the push block 6 is rotatably provided with a movable rod 7, and the upper end of the movable rod 7 is rotatably connected to the lower mold 3 through the same shaft seat.

[0020] By adopting the above technical solution, the driving motor 5 is used to drive the bidirectional screw 4 to rotate;

[0021] The push block 6 is affected by the thread and moves in the opposite direction, thereby using the movable rod 7 to lift the lower mold 3 upward;

[0022] The push blocks 6 move toward each other, which reduces the spacing between the lower ends of the movable rods 7, while the spacing between the upper ends is always fixed and the length of the movable rods 7 is also fixed, which causes the movable rods 7 to lift upward.

[0023] Furthermore, cylinders 8 are fixedly mounted on the inner walls of the four corners of the base 1 , and the same upper die base 9 is fixedly mounted on the upper end of the cylinder 8 .

[0024] By adopting the above technical solution, the cylinder 8 can drive the upper die base 9 to move up and down.

[0025] Furthermore, an upper mold 10 is fixedly mounted on the middle portion of the lower surface of the upper mold base 9 , and the shape of the upper mold 10 matches that of the lower mold 3 .

[0026] By adopting the above technical solution, the upper mold 10 will move synchronously with the upper mold base 9. After the upper mold base 9 and the lower mold base 2 are closed, the upper mold 10 and the lower mold 3 will extrude to form the lens.

[0027] Furthermore, a converging groove 12 is provided at the middle of the left and right sides of the upper surface of the base 1, and a spring 13 is fixedly installed below the inner surface of the converging groove 12;

[0028] Baffles 11 are fixedly mounted on the left and right sides of the lower surface of the upper die base 9 , and the lower ends of the baffles 11 are slidably disposed inside the convergence groove 12 .

[0029] By adopting the above technical solution, the baffle 11 is inserted into the convergence groove 12 to form a barrier on both sides of the film body, which can prevent the liquid inside the equipment from splashing out during mold closing and causing harm to surrounding personnel;

[0030] The spring 13 provides a reverse thrust to the upper die holder 9 through the baffle 11 when the upper die holder 9 is pressed downward, so that the force applied to the upper die holder 9 when moving downward is more linear, thereby avoiding damage to the die body itself caused by the instantaneous pressure generated by the mold closing.

[0031] Working principle: When using the mold that can produce a variety of lenses, first, according to the thickness of the lens to be produced, the driving motor 5 is used to drive the bidirectional screw 4 to rotate. At this time, the push block 6 is affected by the thread and moves in the opposite direction, so that the movable rod 7 is used to lift the lower mold 3 upward, changing the distance between the lower mold 3 and the upper surface of the lower mold base 2. The position of the lower mold 3 can be changed according to the requirements of different lens thicknesses. After the adjustment is completed, the production material can be injected, and the cylinder 8 drives the upper mold base 9 to move downward, so that the upper mold 10 moves downward synchronously to carry out the mold closing and molding work. When closing the mold, the baffle 11 is inserted into the convergence groove 12 , forming a barrier on both sides of the mold body, which can prevent the liquid inside the equipment from splashing out during mold closing and causing harm to surrounding personnel, thereby improving the safety protection of the equipment for personnel. The spring 13 provides a reverse thrust to the upper mold base 9 through the baffle 11 when it is pressed down, making the force of the upper mold base 9 moving downward more linear, avoiding the instantaneous pressure generated by mold closing and causing damage to the mold body itself. After molding, the upper mold base 9 is removed from the mold, and the drive motor 5 can be started again at this time to make the lower mold 3 continue to move upward, protruding from the lower mold base 2, so as to facilitate manual demolding of the molded lens. This is the working principle of the mold that can produce multiple lenses.
