Description

Thermoformed sheet pressing device

The present invention relates to a thermoforming sheet pressing device, which is specifically referred to herein as being capable of stably pressing the peripheral edges of the softened thermoplastic sheet with a suitable uniform force. According to the conventional stretching, the appearance is smooth and wrinkle-free, and the thickness of the entire three-dimensional shell is uniform. A thermoformed sheet press that is not only beautiful but also more impact resistant.

However, with the development of the economy and the improvement of the income of the people, the average gross domestic product (GDP) of Taiwan has exceeded 20,000 US dollars since 100 years, and people's requirements for quality of life have also increased, coupled with the holiday holidays. There are more and more days of vacations. Therefore, many people choose to travel abroad to arrange leisure activities for consecutive holidays. Not only can they relax, but they can also improve the good relationship between family members and friends and relatives. Almost everyone has a suitcase for use abroad, and the old soft suitcase made of traditional cloth is not only easy to be dirty, but also difficult to clean, and often caused by the rapid handling of the carrier during the flight. , or the squeezing between the trunk and the trunk, so that the edge of the sewing is easily cracked or squashed and blasted, and in serious cases, the contents are damaged, causing unpredictable loss to the user, therefore, the tradition The old soft suitcase made of cloth has gradually been replaced by a hard suitcase with a hard outer casing and enough to protect the contents, while the hard suitcase Traditional molding methods, the thermoplastic sheet thermoforming process, often can not produce the desired result of the upper mold and the lower mold die forming multiple creases forming trouble The smooth three-dimensional outer casing, so the traditional manufacturer pulls the four sides of the sheet during the forming process, and then stretches the thermoplastic sheet to form a three-dimensional shell by clamping the upper and lower molds, but the tension on the four sides is often not averaged. The thickness of the formed three-dimensional luggage case is not uniform, and when it is hit by an external force, its thinner portion is easily broken, and at the same time, when one side of the pulling force is too small, wrinkles are generated. It is impossible to form a smooth and beautiful outer casing surface. If one side of the pulling force is too large, the sheet may be stretched too thin and cracked, resulting in the whole sheet being unusable. In addition, sometimes the sheet cannot be firmly pulled, resulting in a stable pulling of the sheet. The occurrence of slippage occurs, so that the non-performing rate is high, the production speed is slow, and the cost of manufacturing is increased. From the above, these shortcomings are the long-term drawbacks of the conventional manufacturing method of the hard-shell luggage. In view of this, how to compress and shape the peripheral edges of the sheet with a suitable uniform force when the thermoplastic sheet is press-formed, and then form No wrinkles along the beautiful three-dimensional shell suitcase, significantly enhance the quality and hard luggage production yield, but this creation wishes to solve technical problems and technical effects.

In view of the above-mentioned problems in the traditional method of manufacturing the trunk of the suitcase, the creator has not been able to break through, and has carefully studied, and then actively researched and developed, and after years of professional experience and experience in this industry, he created the case. Creation.

The main purpose of the present invention is to provide a thermoforming sheet pressing device, wherein four pressing devices are respectively disposed on four sides of the upper seat, and each pressing device further comprises a pushing mechanism, and the axis of the pushing mechanism protrudes downward and can be stretched up and down. a telescopic shaft, a vertical pressing seat is vertically fixed on the end of the telescopic shaft, and the first guiding rod and the second guiding roller are vertically fixed on the pressing seat on the left and right sides of the telescopic shaft a rod, the first guide rod and the second guide rod extend upwardly through the upper seat opposite to the end of the pressing seat and are in an upper and lower movable state, so that the pressing seat is balanced when moving up and down; Two positioning columns, the pressing plate is pivoted under the pressing seat and parallel with the pressing seat; the four receiving seats are respectively fixed on the four sides above the lifting seat, so that the four receiving seats are surrounded to form a capacity Space is set, and each socket has a flat portion, and the flat portion is just parallel to the corresponding pressing plate; when the outer shape of the luggage case is to be manufactured, the thermoplastic sheet is heated and softened, and then placed in the master mold and the four sockets. Above, at this time, the telescopic shaft of the pushing mechanism is pushed down first, so that the pressing plate below the pressing seat is pressed down against the four edges of the softened thermoplastic sheet, because of the setting between the pressing seat and the pressing plate. There is a compression spring, so that the pressing plate can firmly press the peripheral edge of the thermoplastic plate with a proper uniform force, and then push up the hydraulic shaft of the hydraulic mechanism above the base to push the lifting frame upwards, so that the pressing plate The die and the upper male die are aligned with each other. ), since the four edges of the softened thermoplastic sheet are uniformly pressed and tight by the pressed plate, the outer surface is stretched and pressed to produce a smooth and wrinkle-free appearance, and the thickness of the entire three-dimensional shell is uniform, not only beautiful but also beautiful. The impact-resistant luggage case not only has a fast manufacturing speed and low cost, but also has good quality, which greatly enhances the visual beauty and high-grade appearance of the luggage, and enhances the best economic benefits of manufacturing the luggage.
