Problems solved by technology

The mold material used in the mold is density board, etc., which itself is a source of pollution. The dust produced by CNC machining is difficult to control, and the powder and leftover materials cannot be recycled and reused.
In the prior art, metal molds processed and manufactured by metal 3D printing integrated equipment, due to technical limitations, the processed metal shells are thin and easily deformed, and cannot be used as casting molds

Embodiment 1

[0022] see figure 1 and figure 2 , the present invention provides a technical solution:

[0023] A composite resin metal mold, the composite resin metal mold includes a metal layer 1, a resin fiber layer 2 and a metal support frame 3, the resin fiber layer 2 is arranged on the back layer of the metal layer 1, and the metal support frame 3 runs through One end of the resin fiber layer 2 is fixedly connected to the inner side of the metal layer 1 , and the other end protrudes from the resin fiber layer 2 .

[0024] In order to further improve the processing efficiency of the metal layer 1, the metal layer 1 is processed by casting, forging and milling integrated metal 3D printing equipment, and the thickness is about 2-3mm. This method solves the dust pollution in the process of traditional mold processing question.

[0025] In order to further improve the stability and strength of the mold, the metal support frame 3 is T-shaped, and the metal support frame 3 and the metal l...

Embodiment 2

[0035] Manufacture a large mold with a length of 8m. Due to the small processing stroke of the 3D printing equipment, the metal layer 1 is decomposed into 4 modules according to the design of the drawing for metal 3D printing processing and molding. On a high-precision flat plate, according to the actual size of the drawing of the mold The shape is lofted and assembled according to the positioning line, and the 4 metal layer modules are combined into a complete large-scale mold metal layer 1, and then the metal layer 1 and the metal support frame 3 are connected through the preset screw holes and / or bolts on the back, and finally the The resin fiber layer 2 is laid on the back layer of the metal layer 1, and the steps are as follows: heat the modified resin to 30°C in a constant temperature box for 50 minutes; spray a thin layer on the back layer of the metal layer 1 with a thickness of 0.1-0.3 mm modified resin, when it is semi-gel, apply the second layer of modified resin qui...

Abstract

The invention discloses a composite resin metal mold and a manufacturing method thereof. The composite resin metal mold includes a metal layer (1), a resin fiber layer (2) and a metal bracing frame (3), wherein the resin fiber layer (2) is arranged at the back layer of the metal layer (1), one end of the metal bracing frame (3) is in fixed connection to an inner side of the metal layer (1) through the resin fiber layer (2), and the other end extends out of the resin fiber layer (2). Through adoption of the metal layer and the resin fiber layer, the technical problem that a traditional resin mold doesn't resist to wear or temperature and is complicated in processing and the technical problem that a 3D-printed metal layer is too thin and low in strength are solved. The composite resin metal mold is good in dimensional stability, hardness, tensile strength, wear resistance and thermal resistance.

Description

technical field [0001] The invention belongs to the technical field of mold processing, and in particular relates to a composite resin metal mold. Background technique [0002] China is a big casting country in the world, and casting molds have broad development space and innovation. However, due to the manufacturing method of the mould, the manufacturing process of the female mold and / or the male mold forming the master mold is relatively complicated and cumbersome. Compared with metal molds, resin molds are not wear-resistant and temperature-resistant (the use temperature is limited to within 80 degrees). The input of tire mold materials is large, the capital is large, and the processing cycle of CNC engraving and milling machine and / or woodworking engraving machine is long. The patent ZL200710010860.3 "Method for Making Environmentally Friendly Composite Resin Mold" belongs to this category. Among them, the mold tire mold material used is density board, etc., which its...
