Description
Technical field
The utility model relates to a kind of Design of Dies, particularly relates to a kind of high accuracy processing mold ensureing its inner circle circularity for nonstandard ring-shaped pouring plastic product.
Background technology
In the nonstandard moulding of various uses, planform, material, having a kind of ring-shaped pouring plastic, is the most important thing being respectively engaged in injection mould processing enterprise improving product quality and self competitiveness.In this area, the product of injection mo(u)lding is through cooling big city generation contraction distortion to a certain degree, and for relating to the product of circular port, contraction distortion certainly will affect the circularity of circular port.The machining accuracy of mould can by limited mensuration and repeatedly reconditioning ensured, and the contraction distortion of product has certain uncontrollability.Particularly urgent to the die modifications scheme of this reasonable.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes the processing mold that a kind of ring-shaped pouring plastic protects inner circle circularity.
The purpose of this utility model will be achieved by the following technical programs: a kind of ring-shaped pouring plastic protects the processing mold of inner circle circularity, be made up of upper die and lower die, the ring-shaped pouring plastic processed is the cylindrical sleeve with axially circular inward recess, there are inside inward recess two grooves established relatively, the top surface of ring-shaped pouring plastic is smooth, it is characterized in that: described patrix is provided with the first die cavity, described counterdie is provided with the second die cavity, projection and several boss around projection distribution, the split shape corresponding ring-shaped pouring plastic outline of two die cavities, the shape of the corresponding inward recess of shape of described projection, several shrinkage holes formed between the corresponding ring-shaped pouring plastic outer wall of described boss and inward recess, and boss is greater than the interval of peripheral position at the interval of respective slot position.
Further, described ring-shaped pouring plastic is fillet square cylindrical sleeve, and ring-shaped pouring plastic is greater than the wall thickness at each limit place relative to the wall thickness of inward recess in corner place, and the interval at the corresponding corner place of described boss is less than the interval at corresponding each limit place.
Further, described ring-shaped pouring plastic is elliptical cylinder-shape sleeve, and the wall thickness of the relative inward recess of ring-shaped pouring plastic in major diameter place is greater than the wall thickness at minor axis place, and the interval at the corresponding major diameter place of described boss is less than the interval at corresponding minor axis place.
Apply processing mold of the present utility model, die cavity transformation is made for product easy shrinkage distortion place, shaping interiors of products is made to form the brace rod rib of one fixed width differentiation, the shrinkage anti-deformation of ring-shaped pouring molding product inward recess after two grooves are set is ensured with this, ensure inner circle circularity, significantly improve product quality.

Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
The purpose of this utility model proposes the processing mold that a kind of ring-shaped pouring plastic protects inner circle circularity.This ring-shaped pouring plastic processed is the cylindrical sleeve with axially circular inward recess, and have two grooves established relatively inside inward recess, the top surface of ring-shaped pouring plastic is smooth.Due to the existence of two grooves, there is larger contraction distortion in injection molding part in cooling procedure, thus very easily and have a strong impact on the circularity of inward recess.
And the utility model is devoted to this improvement, is not changing injecting products monnolithic case and affecting on the basis of its practical application.As shown in Figure 1 to Figure 3, this ring-shaped pouring plastic protects the processing mold of inner circle circularity, be made up of upper die and lower die, its architectural feature is that patrix 1 is provided with the first die cavity 11, and the streamlined smooth arc-shaped surface had in the first die cavity 11 slightly larger than projection 221 external diameter set in the second die cavity 21, counterdie 2 is provided with the second die cavity 21, projection 221 and several boss 222 around projection distribution, the split shape corresponding ring-shaped pouring plastic outline of two die cavities, the wherein shape of the corresponding inward recess of the shape of projection 221, and several shrinkage holes formed between the corresponding ring-shaped pouring plastic outer wall of above-mentioned multiple boss and inward recess, and boss is greater than the interval b of peripheral position at the interval a of respective slot position.Form thicker brace rod in the position that shrinkage distortion occurs easily to occur thus, suppress shrinkage amplitude.
From further scheme, this ring-shaped pouring plastic is fillet square cylindrical sleeve, and ring-shaped pouring plastic is greater than the wall thickness at each limit place relative to the wall thickness of inward recess in corner place, and the interval at the corresponding corner place of boss is less than the interval at corresponding each limit place, and it suppresses shrinkage principle the same.
In like manner, when ring-shaped pouring plastic is elliptical cylinder-shape sleeve, and the wall thickness of the relative inward recess of ring-shaped pouring plastic in major diameter place is greater than the wall thickness at minor axis place, and the interval at the corresponding major diameter place of boss is less than the interval at corresponding minor axis place.
Apply processing mold of the present utility model, die cavity transformation is made for product easy shrinkage distortion place, shaping interiors of products is made to form the brace rod rib of one fixed width differentiation, the shrinkage anti-deformation of ring-shaped pouring molding product inward recess after two grooves are set is ensured with this, ensure inner circle circularity, significantly improve product quality.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
