Description

Technical Field

[0001] The present invention relates to a mold manufacturing method, in particular to a method and a mold for manufacturing a drop molding mold based on naked-eye 3D technology and a paper mounting process, and belongs to the field of printing technology. Background Art

[0002] In the field of printing technology, in order to complete the production of some drop-molding products, it is necessary to first make a drop-molding mold according to the product form, and then complete the drop-molding product production through the drop-molding equipment and the drop-molding mold. In the prior art, the drop-molding mold is mainly made of silicone. Silicone molds are durable, corrosion-resistant, and aging-resistant, but they are expensive, complex, and difficult to produce. With the advancement of printing technology and the iterative update of printing methods, combining printing methods with drop-molding molds to reduce costs while producing new products that better meet consumer needs has become the main problem that the present invention aims to solve. Summary of the Invention

[0003] In view of the above-mentioned existing situation, the present invention aims to provide a method for making a drop-molding mold using printing technology and a mold made according to this method, so as to reduce the production cost and production cycle of the drop-molding mold, simplify the production process, and thereby improve the ornamental value of the drop-molding finished product to meet the ever-increasing production and consumption needs.

[0004] The present invention is achieved through the following technical solutions: The method for making a drop mold based on naked-eye 3D and paper mounting technology includes the following steps: Step 1: Use a laminating machine to coat cardboard weighing more than 200 grams with PE film or PVC film.

[0005] Step 2: Mount the cardboard with three or more layers of film and perform outer contour die-cutting to form a mold base.

[0006] Step 3: Use a die-cutting machine to die-cut the top layer of cardboard except the bottom layer of cardboard on the mold base to form a concave-shaped drop mold cavity with a closed bottom.

[0007] Step 4: Spray liquid wax or anti-seepage agent on the inner incision of the drop mold cavity. After drying, the drop mold is completed.

[0008] The step 1 further includes: covering the surface of the bottom paperboard used in the subsequent step with a photoresist film, and printing a three-dimensional pattern based on naked-eye 3D technology on the photoresist film corresponding to the cavity of the drop mold.

[0009] The mold, created using a naked-eye 3D printing and paper-mounting process, consists of three or more layers of composite cardboard. The top surface of the composite cardboard is provided with a closed-bottom, concave-shaped cavity. The inner surface of the cavity is sprayed with liquid wax or an anti-seepage agent. Each layer of the composite cardboard is covered with a PE or PVC film.

[0010] The bottom surface of the cavity of the drop mold is covered with a photoresist film, and a three-dimensional pattern based on naked-eye 3D technology is printed on the photoresist film.

[0011] Each layer of cardboard in the composite cardboard weighs more than 200 grams.

[0012] The method for manufacturing a drop molding mold based on naked-eye 3D and paper mounting technology and the beneficial effects of the mold include: 1. The drop mold made of composite cardboard has low cost, convenient processing and simple production, which avoids the disadvantages of high cost, complex process and long cycle brought by the use of silicone in the existing technology. At the same time, it is environmentally friendly and has a high reusability rate. 2. Use printing technology to print rich three-dimensional patterns in the drop-molding mold, and form a three-dimensional pattern viewing effect based on naked-eye 3D technology on the surface of the drop-molding product, enriching the display content of the drop-molding product, improving the display effect, and forming a new product category that is different from existing drop-molding products; 3. The use of coating and liquid wax can effectively improve the anti-seepage performance of the cavity of the drop mold, ensure the use effect of the mold and improve the performance; 4. The molds made by the method can be suitable for making various drop-molded ornaments, souvenirs and handicrafts. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention is described in further detail below: The method for making a drop mold based on naked-eye 3D and paper mounting technology of the present invention specifically comprises the following steps: Step 1: Use a laminating machine to coat 300g cardboard with PE film. At the same time, coat the surface of the cardboard used as the bottom layer in the subsequent steps with a photoresist film, and print a three-dimensional pattern based on naked-eye 3D technology on the photoresist film corresponding to the cavity position of the subsequent drop mold.

[0015] Three-dimensional patterns can be made three-dimensional by using corresponding software tools to transform flat graphics, and then printed on the photoresist film at the corresponding position, thereby forming a three-dimensional pattern effect based on naked-eye 3D technology on the surface of the product that is later drop-molded, thereby improving the display and viewing experience of the product.

[0016] Step 2: Mount the three-layer PE film-covered cardboard by facing it, keeping the cardboard covered with the lithographic film at the bottom position, and then perform outer contour die-cutting on the mounted cardboard to form a mold matrix.

[0017] Step 3: Use a die-cutting machine to perform die-cutting on the other two layers of cardboard of the mold matrix except the bottom cardboard, and form a bottom-closed pit-shaped plastic-dropping mold cavity on the top surface of the mounted cardboard.

[0018] Step 4: Spray liquid wax on the inner cut surface of the plastic-dropping mold cavity. After drying for 12 hours, the plastic-dropping mold is completed.

[0019] Since each layer of cardboard is covered with a PE film, and at the same time, liquid wax is sprayed on the inner cut surface of the plastic-dropping mold cavity, the plastic-dropping mold made of the mounted cardboard has good sealing performance and will not be eroded by the later plastic-dropping process, ensuring the use effect and quality of the mold.

[0020] The mold made according to the above method, such as Figure 1 , includes a three-layer mounted cardboard 1, and a bottom-closed pit-shaped plastic-dropping mold cavity 2 is distributed on the top surface of the mounted cardboard 1. Among them, liquid wax 3 is sprayed on the inner side surface of the plastic-dropping mold cavity 2, and a PE film 4 is covered on the surface of each layer of cardboard in the mounted cardboard 1, and the grammage of each layer of cardboard is 300 grams. To enhance the ornamental value of the mold product, in this example, a lithographic film is covered on the bottom surface of the plastic-dropping mold cavity 2, and a three-dimensional stereoscopic pattern based on the naked-eye 3D technology is printed on the lithographic film.

[0021] When using the mold to perform product plastic-dropping production, a three-dimensional stereoscopic pattern based on the naked-eye 3D technology will be formed on the surface of the finished product, a relatively flat surface will be formed on the back of the finished product during the plastic-dropping process, and at the same time, due to the action of the self-tension of the colloidal plastic, its edge will naturally form an arc transition. When observing the plastic-dropping finished product, the semi-transparent plastic-dropping finished product will form a magnifying effect on the surface three-dimensional stereoscopic pattern, thereby forming a brand-new display effect and meeting the increasing ornamental needs of the majority of consumers.
