Abstract

A method for integrally forming shoesoles mainly comprises: (1) preparing a TPU film; (2) mounting a transparent blank of shoesole into the mold for preheating; (3) applying an adhesive on the TPU film and mounting the film on the mold; (4) thermally pressing and forming the shoesole; and (5) opening the mold; through the above five steps, a TPU film can be firmly bonded to one side of the transparent shoesole; furthermore, a printed pattern in the TPU film can be clearly shown through the transparent shoesole; the integral formation of the TPU film and the transparent shoesole can increase the strength and tensile strength of the product.

Description

533126 'V. Description of the invention (l) The present invention provides a method for integrally forming sole printing, specifically, it refers to a method using (1) · pu film production; (2) · placing transparent rough embryo into the mold Preheating step; (3). TPU film gluing and inserting mold step, (4) · Hot pressing forming step; (5) · Die opening and cleaning step, and other five manufacturing steps' produced a stable glued connection, Sole with good product strength and good tensile strength. As the standard of modern technology combined with plastic molding technology continues to improve, various plastic molding technologies are already one of the ten most important technologies in high-tech industries at present, and generally seen in footwear. 66 ancient i7 θ J Cheng dog shell seat mouth is more to shape the knee into steps, production: 4 ί ί, ☆ differs from footwear plastic molding technology ii, so whether the footwear plastic technology has a better two :: become The plastic sole molding technology that the adopters pay most attention to has already changed the motivation of the inventor to develop this case. Ding Zhiwen also asked about the most common shoe soles currently, and the sole is also the main ^! On the market, the transparent pattern of the internal pattern of the transparent pattern of the internal pattern of the method is as follows :, and Production steps; (2). Production steps of transparent soles (through) bottom pressure, mold opening and cleaning work); (3) · transparent soles "steps: nucleus spines: paper bonding steps; (5). Hot pressing gluing / Step, (4). Transfer: ⑺. Complete the cleaning step; Qigu 6) Cow: Thick protective lacquer step. Seven steps can produce 533126, V. Description of the invention (2) Transparent internal pattern on the market Locked for sale by the inventor for improvement. Its paper-made soles (outsourced to compete for it, because of the improvement in the preset bottom and the turn strength, because of the paint spray, the force is not produced by the manufacturer; Second, although the position of the transfer paper, The problem between the printing papers is today, the finished shoe soles. This practice and use of the m3: transparent footwear molding method has been a problem. ☆ This: One :::, will cause the production of general transfer paper to be narrower. : Plastic molding industry), ^ production outsourced (transfer ^ ^ ^, from, The internal drawing of the internal drawing (second time e = transportation material cost, increased equipment cost, clothing transfer, and A cost) have also indirectly reduced the marketability of the product. After the conventional transfer paper is pasted, it must be heat-pressed. It does not completely cover the entire side of the sole, but it is partially fitted and the transfer paper itself does not have thickness and strength. Therefore, the shoe joint is still not stable. Transfer paper often affects the sole rubber. For this reason, in view of the above defects, it is ideal Practicality and sincerity are extremely important to pursue the goal of improvement. In view of this, the inventor of this case has carefully considered and has been engaged in the sales and research of various types of plastic molding institutions and related transparent footwear products for many years. Development = experience, and finally it is possible to develop an integrated sole printing method with additional functions such as stable glue connection, increased αα strength, sufficient tensile strength, etc. 2. The primary purpose of the present invention is to provide a product that can increase product strength. The method for integrally forming sole printing with f ί force, the present invention mainly uses the TPU film production steps in six manufacturing steps; the TPU film is glued, placed

533126, V. Description of the invention (3) Step of entering the mold; Step of hot pressing; Three steps, the Ding Pu film can be completely covered on the entire surface of the sole, and the TPU film has a certain material thickness (the Ding PU The material of the outer film of the film is the same as that of the sole), so the present invention can indeed firmly join a piece of TPU film on the side of the sole, thereby enhancing the strength and tensile strength of the sole. The secondary object of the present invention is to provide a method for integrally forming sole printing with more stable glue connection of the product. The material of the outer film of the butadiene p U film of the present invention is the same as that of the sole, and the thermocompression bonding is performed while being glued. ^ The invented TP U film is completely integrated with the sole, and the finished product is indeed more stable. According to the present invention, one of the following manufacturing steps is featured. First, as shown in the second figure, the sole printing integrated molding method includes the following steps: Step F two Z film production steps: The TPU film is made of- Pattern 4 τ2: 70% of the film, and the material of the outer film is the same as that of the sole, and the shape of the pu film corresponds to the sole; 耵 & 耵 贝 和 底 粗 ： 益 i 模 ί: shoes :::: into the mold Preheating step: put transparent shoes; inside, then put the 3rd transparent shoe sole rough mold and the mold-and heat the film against the paralyzed social tiger such as n — W. First put the mold step: on the surface of the Ding ~ 4 sole rough embryo Glue, and make the Ding Pu film stick I on the I ^ f ^ D PU film and put the sleeping sheet on the rough sole surface of Θ sole

533126 V. Description of the invention (4) (4) • Hot pressing forming step: hot pressing the TPU film and the rough shoe sole with a mold to fuse the outer film of the TPU film and the rough shoe sole into a finished shoe sole; (5) • Mold opening cleaning step: After the mold is opened, the finished product is taken out and the cleaning worker is removed. Regarding the detailed methods and other effects adopted by the invention of the present case to achieve the above-mentioned objects, technologies, a preferred embodiment can be listed and illustrated in detail in conjunction with the drawings. It is believed that the object, features and other advantages of the invention of the present case can be used. Get an in-depth and specific understanding; please refer to the third, fourth, fifth, and sixth figures. The present invention is performed according to the following operating steps and means: (1) · TPU film production steps: This DPU film (1 〇) is covered with a pattern layer (1 1) inside the upper and lower outer film (12), and the material of the outer film (1 2) is the same as the material of the rough sole (2 1), and the TPU film (1 0) The shape exactly corresponds to the shape of the preset rough sole (2 1); (2) · Transparent sole rough embryo is placed in the mold Preheating step: A transparent sole rough embryo (2 1) is placed in the mold ( 2 2), and the transparent shoe sole rough embryo (2 1) and the mold (2 2) — and heated to a preset temperature; (3) • Ding PU film, placing the mold steps: in the Ding pu The film (1 0) is glued to the surface of the rough sole (2 1) of the sole, and the TPU film (1 0) is placed in the mold (22). And allowing the TPU film (10) attached to the surface of the He crude embryo sole (21) is; (4) • · hot press forming steps using molds (22) of the hot-butoxy
