Embodiment Construction

[0028] The present invention will be further described below in conjunction with embodiment.

[0029] The manufacturing method of the stainless steel forming mold of the pulp molding comprises the following steps:

[0030] Step 1: According to the shape and size of the pulp molding, respectively produce the upper mold mother and the lower mold mother used to manufacture the stainless steel forming mold;

[0031] Step 2: Clean the upper mold mother and the lower mold mother, then apply a release agent on the upper mold mother and the lower mold mother respectively, and then cover the upper mold mother and the lower mold mother;

[0032] Step 3: inject the wax liquid into the cavity formed between the upper mold mother and the lower mold mother, and make the wax liquid fill the cavity;

[0033] Step 4: Stop the injection of the wax liquid, wait for a certain time, the wax liquid will solidify in the cavity, and then separate the upper mold mother and the lower mold mother, and ...

Abstract

A manufacturing method of a pulp-molded stainless steel forming die comprises the steps: injecting a wax liquid into a cavity formed between an upper die nut and a lower die nut, forming, by the curedwax liquid, a wax female die, and then drilling the wax female die manually, wherein a plurality of dense filtering holes can be formed in the wax female die; soaking the wax female die with the drilled holes in a high-temperature-resistant liquid material to form a protective layer on the outer surface of the wax female die, then placing the wax female die with the protective layer attached to the surface in a heating furnace to be heated, melting the wax female die inside, enabling the melted wax female die to flow out of a liquid flowing channel, and then fully casting a stainless steel liquid into the protective layer; then conducting natural cooling and curing; and finally, removing the outer protective layer, wherein the left cured stainless steel is the stainless steel forming diewith a plurality of dense filter holes. The whole manufacturing process is simple, convenient in production and processing and low in cost, the stainless steel forming die is produced and processed ina simplified manner effectively, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method for manufacturing a stainless steel forming die, in particular to a method for manufacturing a stainless steel forming die for pulp molding. Background technique [0002] Pulp molding with plant fiber as the main raw material is to use a forming mold to shape the pulp in the pulp state to make a finished product. This technology does not require any adhesives and can be made into paper with complex shapes and high dimensional accuracy requirements. Products are a technology to obtain ideal packaging materials. The products meet the needs of health, sanitation, environmental protection, speed and convenience. The products can be completely degraded naturally after being used and discarded, making them an emerging environmental protection product. Therefore, it is widely used in the packaging of food, electronics, electrical appliances, or glass products that are fragile, easy to break, or must avoid extrusion. [0003]...
