Description

Technical Field

[0001] This invention relates to the field of cork processing technology, specifically a molding process for cork production. Background Technology

[0002] Currently, cork products on the market are all manufactured using machining processes, where large pieces of cork are processed into various products using grinding tools. During the manufacturing process, the various cutting and grinding equipment generates a large amount of waste, which cannot be reused, resulting in significant cost losses. Furthermore, cork products are processed piece by piece, leading to low production efficiency. Additionally, machining irregularly shaped products is difficult and complex, hindering large-scale production. Summary of the Invention

[0003] The purpose of this invention is to provide a molding process for cork production to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a molding process for cork production, comprising the following steps:

[0005] Step 1: Select a mold of suitable specifications and fix the upper and lower molds onto the hydraulic press respectively;

[0006] Step 2: Open the upper and lower molds and pour the sticky cork granules into the material cavity of the lower mold;

[0007] Step 3: The upper mold is moved down into the material cavity by the hydraulic press, and the sticky cork particles in the material cavity are extruded and shaped.

[0008] Step 4: Heat the mold for 3-4 hours at a temperature of 100-120℃;

[0009] Step 5: Cool the heated mold to room temperature and demold it.

[0010] As a further aspect of the present invention: the selection of the applicable specification mold in step one is based on the shape of the internal material cavity of the mold. The internal shape of the mold is diverse, and different shapes of hot pressing molds can be selected according to actual production needs, so that hot pressing products of different shapes can be prepared, making the preparation of irregular products more convenient and easier.

[0011] As a further aspect of the present invention, the processing steps for the adhesive cork particles are as follows:

[0012] S1. The oak bark material is successively crushed, milled, and air-classified to obtain cork particles;

[0013] S2. Add the obtained cork granules and environmentally friendly glue into a mixer in a certain proportion and mix for 30-50 minutes.

[0014] S3. Take out the material obtained after stirring and mixing to obtain sticky cork particles.

[0015] As a further aspect of the present invention, in step S2, the ratio of cork particles to environmentally friendly adhesive is 3:2 by mass.

[0016] As a further aspect of the present invention: the environmentally friendly adhesive used in step S2 is a resin adhesive, and a rubber adhesive can also be used. Both are environmentally friendly adhesives, which makes the prepared hot-pressed product more environmentally friendly.

[0017] As a further aspect of the present invention, the cooling time of the product after molding in step five is 2-4 hours, which facilitates the gradual stabilization of the product performance obtained by hot pressing.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The molding process used in this cork production method allows waste generated from subsequent sanding and polishing of cork products to be mixed with other cork granules in a mixing tank to prepare viscous cork granules, thus avoiding waste of cork materials and greatly reducing the cost of cork product production.

[0020] 2. The molding process for cork production allows for the simultaneous production of multiple cork products using a multi-cavity mold, thereby effectively improving the production efficiency of cork products.

[0021] 3. The molding process used in this cork production allows for the selection of appropriate molds based on the actual shape of the cork product before production. This effectively simplifies the production process of irregularly shaped cork products, making the process simpler and more convenient. It also enables large-scale production with a higher yield.

[0022] 4. The molding process used in this cork production process produces cork products with a better appearance and higher density, resulting in better performance during subsequent use. Attached Figure Description
