Abstract
The invention discloses a plastic forming mold for producing a coil rack, and belongs to the field of thermal forming. The plastic forming mold consists of a fixed mold core (1), a movable mold plunger (3) and a fixed mold core plug (2), wherein the fixed mold core plug (2) is installed on the inner side of the fixed mold core (1) and forms a plastic forming cavity (4) with the fixed mold core (1), the movable mold plunger (3) is arranged inside a material filling chamber (5) on the top of the fixed mold core (1), the bottom end of the movable mold plunger (3) has a rounded angle (7), and the root part of the filling chamber (5) has a rounded angle (6). By adopting the plastic forming mold, the loss caused by large local stress on a right angle on the bottom end of the movable mold plunger in the mold pressing process can be avoided, no raw material is clamped on the root part of the filling chamber, the movable mold plunger is tightly attached with the bottom of the filling chamber, and the qualification rate of products can be increased.
Description
Technical field
The present invention relates to die device, particularly relate to a kind of mould for plastics of bobbin processed.
Background technology
Mould for plastics is to utilize given shape to have the instrument of certain interior shape and size goods.At present in the mould for plastics of existing a kind of bobbin processed, the root of its material feeding chamber is right angle, the Ye Wei right angle, bottom of dynamic model plunger, its design causes when designing at die work, in the time of may be because of mold pressing, pressure be excessive, the right angle, bottom that causes dynamic model plunger is in concentrated stress and chipping phenomenon, and the right-angle design of material feeding chamber root, make in mold process, because of dynamic model velocity of plunger too fast, make part material be stuck in material feeding chamber root, cause the bottom of dynamic model plunger and material feeding chamber not to be close together, make underproof plastics bobbin, increased production cost.
Summary of the invention
For solving the defect existing in prior art, the invention provides a kind of mould for plastics of bobbin processed, the mould for plastics of this bobbin processed, by changing mould structure, is effectively avoided the damage at right angle, dynamic model plunger bottom.
The present invention is achieved by the following technical programs:
A kind of mould for plastics of bobbin processed, fixed mold, dynamic model plunger and cover half core plug, consist of, cover half core plug is arranged on fixed mold inner side, forms plastic shaping chamber with fixed mold, its two head width is with fixed mold width than being 2:1, and its intermediate width is 5:4 with fixed mold width ratio;
Dynamic model plunger is placed on that the material feeding at top of fixed mold is indoor, and wherein the bottom of dynamic model plunger is fillet, and the root of material feeding chamber is fillet.
The bottom fillet radian size of dynamic model plunger equates with the root fillet radian of material feeding chamber.
Beneficial effect of the present invention is: avoided right angle, dynamic model plunger bottom in mold process to damage because local stress is excessive, guaranteed to be stuck in material feeding chamber root without raw material simultaneously, the bottom of dynamic model plunger and material feeding chamber is close together, has increased product percent of pass.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present invention
Wherein: 1-fixed mold, 2-cover half core plug, 3-dynamic model plunger, 4-plastic shaping chamber, 5-material feeding chamber, 6-fillet, 7-fillet.
The specific embodiment
Below in conjunction with accompanying drawing, further describe technical scheme of the present invention:
A mould for plastics for bobbin processed as shown in Figure 1, present embodiment provides a kind of mould for plastics of bobbin processed of circle, comprises fixed mold 1, dynamic model plunger 3 and cover half core plug 2.
Wherein a cylindrical material feeding chamber 5 is arranged at the top of fixed mold 1, and the root of material feeding chamber is designed to fillet 6, has a cylindrical cavity under material feeding chamber, and this cylindrical cavity presents the little shape in large centre, two, half of the diameter material feeding chamber 5 in the middle of it.
Cover half core plug 2 is designed to directly be less than fixed mold 1 cylindrical cavity, to in fixed mold 1 cylindrical cavity of cover half core plug 2, form plastic shaping chamber 4, plastic shaping chamber 4 is the little shape in large centre, two, its two head width is with fixed mold 1 width than being 2:1, and its intermediate width is 5:4 with fixed mold 1 width ratio.
Dynamic model plunger 3 is designed to consistent with material feeding chamber 5 size shape, and wherein the bottom of dynamic model plunger 3 is fillet 7, and the radian of its fillet 7 is identical with the radian of the root fillet 6 of material feeding chamber.
Before material feeding, first cover half core plug 1 is fixed in the cylindrical cavity of fixed mold 1, then carries out material feeding, after material feeding is full, dynamic model plunger 3 is at the uniform velocity pressed in material feeding chamber 5, when dynamic model plunger 3 and the root of material feeding chamber are closely linked.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its objective is to allow and be familiar with these those skilled in the art and can understand content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalents or modification that according to the present invention, spirit essence has been done, all should contain in protection scope of the present invention.
Claims (2)
1. a mould for plastics for bobbin processed, is comprised of fixed mold (1), dynamic model plunger (3) and cover half core plug (2), it is characterized in that:
Cover half core plug (2) is arranged on fixed mold (1) inner side, form plastic shaping chamber (4) with fixed mold (1), plastic shaping chamber (4) is the little shape in large centre, two, its two head width and fixed mold (1) width are than being 2:1, and its intermediate width and fixed mold (1) width is than being 5:4;
Dynamic model plunger (3) is placed in the material feeding chamber (5) at top of fixed mold (1), and wherein the bottom of dynamic model plunger (3) is fillet (7), and the root of material feeding chamber (5) is fillet (6).
2. the mould for plastics of bobbin processed as claimed in claim 1, is characterized in that: bottom fillet (7) the radian size of described dynamic model plunger (3) equates with root fillet (6) radian of material feeding chamber (5).
