Abstract

The invention discloses an ultrasonic hot melting device and method. The ultrasonic hot melting device comprises a surrounding-type heating assembly and an ultrasonic molding assembly. The surrounding-type heating assembly comprises a heating mould; one or more heating mould heads are arranged at the bottom of the heating mould; each heating mould head is a tubular body with the inside hollowed and the periphery closed; the dimension of the hollowed part of each tubular body is matched with the external dimension of a hot melting part of a workpiece; and before preheating, surrounding-type preheating is conducted after the hot melting part of the workpiece is sleeved with one tubular body from top to bottom. The ultrasonic molding assembly comprises an ultrasonic vibrator and a hot melting mould. The bottom of the ultrasonic vibrator is connected with the hot melting mould, and the bottom of the hot melting mould is provided with a plurality of hot melting mould heads used for press molding. The hot melting mould heads along with the hot melting mould are driven by the ultrasonic vibrator to conduct press molding. The ultrasonic hot melting device and method have the advantages that the heating is even without blind angles, the heating speed and the efficiency are high, the melting penetration effect is good, the hot melting mould is durable and long in service life, the surface of a product is full and good in degree of finish, and the tensile force of the product is sufficient.

Description

technical field

[0001] The invention relates to the field of workpiece hot-melt technology, in particular to an ultrasonic hot-melt device and method. Background technique

[0002] The hot melt molding of existing workpieces mainly consists of the following methods. Method 1: Preheat the plane first, then pause, and then press down to form. This method has the following disadvantages: 1. The glue of the workpiece is not heated thoroughly, and it is prone to deformation and broken feet during molding; 2. The surface of the workpiece after processing is not smooth, and it is easy to produce wire drawing; 3. After molding, it is easy to appear unfulfilled products. , causing product defects; 4. The product after heating and hot-melt molding has insufficient tension and is easy to break; Accurate, 6. The hot-melt mold and the heating mold are the same mold, and the hot-melt mold is not durable and has a short life. The second way is to preheat the plane first, and then carry ...

Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the product of the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0035] Such as Figure 1 to Figure 3 As shown, the ultrasonic hot-melt device includes an enveloping heating assembly and an ultrasonic forming assembly, the enclosing heating assembly and the ultrasonic forming assembly are arranged side by side on a fixed frame 10, the enclosing heating assembly includes a heating mold 1, and the heating The bottom of the mold 1 is provided with a single or multiple heating dies 2 protruding from the heating mold 1 and used for preheating the workpiece. The heating die 2 is a cylindrical body 3 with a hollow interior and a closed circumference. The size of the inner hollow part matches the outer size of the hot-melt part of the workpiece. Before preheating, the cylindrical body 3 i...
