Plastic vacuum forming mold and manufacturing method of arc plastic vacuum forming product

Abstract

The invention relates to a plastic vacuum forming mold and a manufacturing method of an arc-shaped plastic vacuum forming product. The plastic vacuum forming mold comprises a main body cushion block and two auxiliary cushion blocks, wherein the top of the main body cushion block is provided with an arc-shaped supporting surface matched with the inner concave surface of an arc-shaped workpiece, the two opposite sides, corresponding to the width direction of the arc-shaped workpiece, of the main body cushion block are each provided with a slope, the slopes incline outwards from top to bottom and are used for supporting a plastic vacuum forming film, and the two auxiliary cushion blocks are arranged on the two opposite sides, corresponding to the length direction of the arc-shaped workpiece, of the main body cushion block correspondingly, the sides, away from the main body cushion block, of the auxiliary cushion blocks and the two opposite sides, corresponding to the width direction of the arc-shaped workpiece, of the auxiliary cushion blocks incline outwards from top to bottom, and the auxiliary cushion blocks are used for supporting the plastic vacuum forming film. According to the scheme, the plastic vacuum forming process can be applied to manufacturing of arc products, and the plastic vacuum forming film can be effectively prevented from being broken due to excessive stretching in the film pressing process.

Description

technical field [0001] The invention relates to the technical field of furniture manufacturing, in particular to a method for making a plastic-absorbing mold and arc-shaped plastic-absorbing products. Background technique [0002] At present, most arc-shaped products (such as curved doors) on the market are made by "melamine finish process" or "paint finish process". With the melamine finish, the edge is generally sealed with edge banding. This process has a large size limit, and the high door is easy to deform, and is restricted by the edge banding equipment and material, and the arc edge can only be hand banded. , making it difficult to control the edge sealing quality of the two arc edges, and it is easy to open the glue. However, through paint finishing, due to the complexity of the paint process, on the one hand, it is easy to cause environmental pollution (high investment in environmental protection). Guarantee affects the delivery cycle, and the price of paint produ...

Problems solved by technology

With the melamine finish, the edge is generally sealed with edge banding. This process has a large size limit, and the high door is easy to deform, and is restricted by the edge banding equipment and material, and the arc edge can only be hand banded. , making it difficult to control the edge sealing quality of the two arc edges, and it is easy to open the glue

However, through paint finishing, due to the complexity of the paint process, on the one hand, it is easy to cause environmental pollution (high investment in environmental protection). Guarantee, affect the delivery cycle, and the price of paint products is high, only for high-end customers, fewer customers who have the ability to buy and experience

In addition, the "plastic-absorbing process" commonly used in flat-panel and flat-panel shaped products is difficult to apply to arc-shaped products, especially when the chord height of arc-shaped products is high, it is easy to cause Blister film breaks due to excessive stretching
