Abstract

The utility model provides a plastic molding die with an insert. The plastic molding die comprises a lower template, a middle template, an upper template and a core plug, wherein the upper template, the middle template and the lower template are assembled in an upper-middle-lower structure; the core plug is arranged and fixed on the lower template, and is assembled together with the lower and middle templates to form a plastic molding cavity; an injection chamber is formed in the upper end of the middle template, two same inserts are arranged on two sides of the injection chamber; a bulge part with a rectangular cross section is arranged at the bottom end of the upper template. According to the plastic molding die, by additionally arranging the inserts, the area of the space of the injection chamber can be reduced, the contact area of the bulge part of the upper template and the injected plastic can be reduced, and the pressure intensity of the injected plastic can be increased, so that the injected plastic can be closely attached to the wall of the plastic molding cavity, and the produced plastic finished product is smooth in surface and does not have fine cracking.

Description

The mould for plastics that a kind of band is inserted
Technical field
The utility model belongs to thermoplastic materials mould field, specially refers to the mould for plastics that a kind of band is inserted.
Background technology
In the prior art, as shown in Figure 2, mould for plastics comprises lower bolster (1a), middle template (2a), cope match-plate pattern (3a) and core plug (4a), cope match-plate pattern (3a) wherein, middle template (2a) and lower bolster (1a) are combined by upper, middle and lower, core plug (4) is fixed on the center of lower bolster (1), core plug (4a) and lower bolster (1a), after middle template (2a) assembling, form plastic shaping chamber (6a), material feeding chamber (5a) is in the upper end of middle template (2a), its width is greater than the upper end width in plastic shaping chamber (6a), when this design makes plastics enter plastic shaping chamber (6a), its cavity area is large, plastics are because of the too little pressure of carrying, cause the rough of plastic product, there is blind crack.
Utility model content
For solving the defect existing in prior art, the mould for plastics that the utility model provides a kind of band to insert, the mould for plastics that this band is inserted, by changing its internal structure, makes plastic product smooth surface, the qualification rate of the finished product increasing, has reduced production cost.
The utility model is achieved by the following technical programs:
The mould for plastics that a kind of band is inserted, at least comprise lower bolster, middle template, cope match-plate pattern and core plug, wherein cope match-plate pattern, middle template, lower bolster are Up-Center-Down Structure assembling, and core plug is fixed on the center of lower bolster, after core plug and lower bolster, the assembling of middle template, form plastic shaping chamber; There is material feeding chamber the upper end of middle template, and there are two identical inserting on both sides, material feeding chamber; It is rectangular bossing that there is cross section the bottom of cope match-plate pattern.
Further, the described width of inserting is 1/4 of material feeding chamber width.
Further, the width of described cope match-plate pattern bossing equates with bottom, plastic shaping chamber width, is the twice of plastic shaping chamber top width.
Further, the width of described cope match-plate pattern bossing equates with plastic shaping chamber top width.
Further, the height of described cope match-plate pattern bossing highly equates with inserting.
The beneficial effects of the utility model are: the space of inserting to reduce material feeding chamber by increase, reduce the contact area of cope match-plate pattern projection and injected plastic, increase the pressure of material feeding plastics, make the plastics that inject more be close to plastic shaping chamber wall, the plastic product smooth surface of making, and without blind crack.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present utility model;
Fig. 2 is the cross-sectional schematic of prior art;
Wherein: 1-lower bolster, template in 2-, 3-top panel, 4-core plug, 5-inserts, 6-material feeding chamber.7-plastic shaping chamber, the bottom width in L1-plastic shaping chamber, the width of L2-material feeding chamber, the top width in L3-plastic shaping chamber, the width that L4-inserts, the width of L5-upper module projection, the height that h1-inserts, h2-upper module projection height.
1a-lower bolster, template in 2a-, 3a-cope match-plate pattern, 4a-core plug, 5a-material feeding chamber, 6a-plastic shaping chamber.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model:
The mould for plastics that a kind of band is inserted, at least comprise lower bolster 1, middle template 2, cope match-plate pattern 3 and core plug 4, wherein cope match-plate pattern 3, middle template 2,1 one-tenth Up-Center-Down Structure assembling of lower bolster, core plug 4 is fixed on the center of lower bolster 1, core plug 4 and lower bolster 1, the rear plastic shaping chamber 7 that forms of middle template 2 assemblings, the width L1 of lower end is the twice of upper end width L3; There is material feeding chamber 6 middle template 2 upper ends, and the width L2 of material feeding chamber 6 is twices of the width L3 of 7 upper ends, plastic shaping chamber; It is rectangular projection that there is a cross section lower end of the cope match-plate pattern 3 at the mould for plastics top of inserting at band.
Because plastic shaping chamber 7 presents the large shape of the little following of top, mold pressing make need to be larger pressure, just can make the plastics that inject be close on the wall in plastic shaping chamber 7, but the width L2 of material feeding chamber is the twice of the width L3 of 7 upper ends, plastic shaping chamber, if cope match-plate pattern 3 carries out mold pressing according to original pressure, can make because the contact area of itself and injected plastic is excessive its too little pressure.
In order to overcome the above problems, at the two ends of material feeding chamber 6, add two to insert 5, its width L4 is 1/4 of material feeding chamber 6 width L2, with this, reduced the base area of material feeding chamber 6, meanwhile, also reduce the width of the projection of cope match-plate pattern 3, its width L5 is equated with having added the width of 5 the material feeding chamber 6 of inserting, also equate with the width L3 of 7 upper ends, plastic shaping chamber, the height h2 of the projection of cope match-plate pattern 3 equates with the height h1 in inserting simultaneously.During mold pressing, owing to having added, insert 5, cope match-plate pattern 3 and the contact area of injected plastic are reduced, increased the pressure to injected plastic, plastics in plastic shaping chamber 7 are attached on its inwall more closely, the plastic product smooth surface of making, and without blind crack.
