Abstract
The agricultural power shovel point is a part which is actually contacted with a cultivated land when agricultural machine operates, and belongs to a consumable product with needed hardness distribution and sliding wear resistance. The products are mainly made from high-chromium high-manganese cast iron materials and cast steel materials subjected to heat treatment, and the surface hardness can be over 60HRC during use. At present, the conventional casting technology methods for manufacturing the products comprise sand casting, sand coated iron mould casting, lost foam casting and the like. The lost foam white type manufacturing mold for the agricultural power shovel point disclosed by the invention is mainly characterized by consisting of a male die, a female die, an inner cavity loose piece, a side hole loose piece, a positioning pin, an EPC bead channel, a clamping mechanism and a lifting mechanism. According to the mold, white foams with holes and cavities below a complex product profile of the agricultural power shovel point are realized, and necessary technological equipment is provided for realizing the lost foam casting of the agricultural power shovel point products.
Description
Technical field
The present invention is a kind of evaporative pattern white type mfg. moulding die of farm machinery spear, belongs to lost foam casting field.
Background technology
Farm machinery spear is a kind of part operationally contacted with reality of ploughing at agricultural machinery, belongs to a kind of consumptive material product needing wear resistance.This series products mainly adopts the cast iron materials of Gao Ge, Gao Meng and the cast steel material through Technology for Heating Processing, its in use case hardness can reach more than 60HRC.At present, the casting technique of conventional this series products of manufacture has the technique such as sand casting and the casting of device for sand coated iron mould method; Negative pressure lost foam technique can be applied to the manufacture of this series products as a kind of casting means of environment-friendly high-efficiency, but due to such shape of product comparatively complicated, the manual efficiency manufacturing evaporative pattern white type is very low, is difficult to maintain batch production.The present invention is a kind of evaporative pattern white type mfg. moulding die of farm machinery spear, is a kind of white type foaming mould of novel farm machinery spear.To achieve under farm machinery spear complex product profile with holes foams with the white type of cavity, for the lost foam process casting realizing farm machinery spear product provides a kind of technological equipment of necessity for this mould.
Summary of the invention
The present invention is a kind of evaporative pattern white type mfg. moulding die of farm machinery spear, its main purpose is that achieve under farm machinery spear complex product profile with holes is foamed with the white type of cavity, for the lost foam process casting realizing farm machinery spear product provides a kind of technological equipment of necessity.
To achieve these goals, the present invention is by the following technical solutions:
The present invention is a kind of evaporative pattern white type mfg. moulding die of farm machinery spear, it is characterized in that: comprise punch (1), die (2), inner chamber loose piece (3), side opening loose piece (4), shop bolt (5), EPC bead passage (6), clamping mechanism (7).
When punch (1) and die (2) manufacture, selected material is ZL105; When inner chamber loose piece (3), side opening loose piece (4) manufacture, selected material is ZL105; Single foaming can manufacture 4 to 16 white type.
Punch (1) and die (2) according to the shrinkage ga(u)ge laggard line number control processing and manufacturing of the data model of farm machinery spear by specific materials, and realize location by shop bolt (5); Inner chamber loose piece (3) and side opening loose piece (4) according to the shrinkage ga(u)ge laggard line number control processing and manufacturing of the data model of farm machinery spear by specific materials, and realize being located by connecting by the ad-hoc location on punch (1).
EPC bead passage (6) is arranged on die (2) and realizes injecting of EPC bead; Clamping mechanism (7) is arranged on connection punch (1) and die (2) realizing mould and EPC bead generator.
Inner chamber loose piece (3) and side opening loose piece (4) are designed to mechanism that is detachable and that change, to ensure that mould can provide white type for the farm machinery spear material of reduced scale in 1.2% to 2.5% scope.

Detailed description of the invention
Be further described below in conjunction with the evaporative pattern white type mfg. moulding die of detailed description of the invention to a kind of farm machinery spear of the present invention.
Be below a concrete case study on implementation, content of the present invention is not limited thereto.
Certain type farm machinery spear product (3 d effect graph is see Figure of description 2), during the design of evaporative pattern white type mfg. moulding die, calculates shrinkage ga(u)ge by 1.8% according to the material design of this product, and the Design of Dies white type quantity that at every turn foams is 6; During the technological design of negative-pressure los mould casting running gate system, foundry goods sprue, cross gate and ingate sectional area ratio are 1.2:1.4:1.
During Making mold, punch-die body material selection ZL101, mould final size is 800mm × 450mm × 300mm; Inner chamber loose piece and side opening loose piece select material to be polyurethane plastics, and design form is considered to occur can realize replaceable loose piece, to provide mould to the adaptability of identical product different materials when changing at castings material.
During mould punch-die location, select three shop bolts (in triangle layout), size is Ф 20 × 35mm, and wherein alignment pin design is on punch, and mould and EPC bead generator clamping mechanism are designed to pressing plate flute profile formula, and pressing plate groove is of a size of 25mm × 45mm.
When the foaming of evaporative pattern white type manufactures, expanded material selects expandable polystyrene (EPC bead), and steam of generator pressure is 0.3MPa, and preheating time is 15min, and the white type material object manufactured by evaporative pattern white type mould of final employing the art of this patent as shown in Figure 3.
