Description
Technical field
The present invention relates to the technical field of chopping board production, more particularly to a kind of production of the super thick chopping board of 8-50mm thickness
Method and mould.
Background technology
In the prior art, the technique of production chopping board has following three kinds：
1st, production chopping board (below 8mm) traditional injection moulding technique is specific as follows：Total molding cycle 120s of injection machine or so →
Artificial cutter pares off the unnecessary mouth of a river, then with tool refine → first time pressing plate cooling and shaping flatness：Single chopping board is in cylinder
Under 50 degree, the cooling cycle is controlled in 472s → second pressing plate cooling and shaping flatness for 8 kilograms of pressure, platen temperature control：
Under 8 kilograms of cylinder pressure, pressing plate normal temperature, cooling cycle control is in the inspection of 3-4 hours → product temperature for multiple chopping boards：Measurement dish
The temperature of plate positive and negative → be neatly stacked on clamp 70 chopping boards, 4 days → inspection chopping board is pushed down using 25 kilograms of weight
Whether qualified flatness is, and is packed.
Although injection machine injection molding cycle is only 120s or so, traditional injection moulding in production chopping board traditional injection moulding technique
Technique can only be molded the chopping board of below 8mm thickness and the later stage needs the shaping process of multiple tracks, the required time reach 4 days with
On, the turnover space particularly required for being pressed 4 days with 25 kilograms of weight is larger, so as to cause high cost, complex process, life
The problems such as product floor space is big.
2nd, traditional expressing technique of production chopping board is as follows：Extruder sheet extrusion → embossing → sizing cooling → cut-to-length
→ machining → finished product packing.
Although traditional expressing technique can be molded the chopping board of 8-50mm thickness, in order to ensure presentation quality and plane
Degree, extruded velocity can not be too fast, causes extrusion molding cycle time long, high cost, efficiency low, is carried after the sheet material severing of extrusion
Wedge angle and without overflow groove, hang road machining after porthole, outward appearance fillet need and complete, the outward appearance of product embossing face and machined surface is not
Can accomplish that decoration dermatoglyph is consistent, unsightly.
3rd, traditional oil pressure technique of production chopping board is as follows：Extruder extrusion melting charge → weigh → oil pressure → machining is fallen
Angle/deburring → finished product packing.
Traditional oil pressure technique can also be molded the chopping board of 8-50mm thickness, but this technological forming cycle is long, monolithic shaping week
Phase is about 20-30 minutes, and labor workload is big, and surface due to the even stress trace of inhomogeneous cooling clearly, machining chamfering and
