Abstract
The utility model discloses a kind of auto parts and components high-gloss injection mold, comprise upper mould core, counterdie core rod, sprue and several runners through with sprue, multiple independently die cavity is formed between upper mould core and counterdie core rod, connected by cast gate between the die cavity that each runner is corresponding with it, sprue end is provided with sprue puller, be provided with exhaust mold insert in die cavity, below die cavity, be provided with straight thimble, and be provided with oblique top pin below the junction of cast gate and runner.The utility model, by arranging straight thimble and oblique top pin combines, can depart from smoothly with the reinforcement of injecting products inside, and then make the smooth demoulding of whole injecting products; By arranging exhaust mold insert in die cavity, making die cavity form vacuum state, reducing goods and there is bubble situation, improve goods height light quality; Adopt sub marine gate as connecting the passage of each runner with corresponding goods die cavity, making the cast gate place when ejecting goods coagulate material effectively can be separated with plastic member product, does not affect products appearance quality.
Description
Technical field
The utility model relates to Making mold, and it is high to be specifically related to a kind of efficiency, safety, ensures the auto parts and components high-gloss injection mold of the de-fast material of end product quality.
Background technology
At present, auto parts and components etc. are large-scale, the Design of Dies of high-strength injection plastic and manufacturing technology, also there is many technical problems, as runner design is complicated, die size is large, blemish easily occurs product, stripping rate is slow.
De-molding injection molded products is last link in injection molding process, determines the quality of final products, solid and allows product from mold ejection, simultaneously when matched moulds, ensure that he can not interfere with other parts, and homing, to carry out next one circulation.The injecting products of some injection molded is with reinforcement, and because plastic material has shrinkage, injecting products is often stuck on thimble, so cannot the demoulding smoothly under the effect of the straight thimble of injection mold.
In addition, cast gate, as the important channel between connecting passage and die cavity, the profile design of cast gate, the selection of position, can directly have influence on plastic products high-quality injection mo(u)lding.
The type of cast gate has multiple, and at present, common cast gate is drop gate.Plastic melt directly enters die cavity by the large end of sprue, thus has the features such as flow resistance is little, flowing flow process short and pipeline time is long.But, the product of traditional cast gate injection moulding after moulding, usually artificial removal's cast gate is needed, cast gate is excised from goods and removal surface is processed, this operation causes a large amount of manpowers and the wasting of resources, and gate vestiges is obvious, and artificial removal's cast gate not easily ensures quality of item, reduce production efficiency, add production cost.
Sum up the problems referred to above, therefore, research and develop a kind of efficiency high, safety, ensure end product quality, the new automobile parts injection mold that stripping rate is fast, just becomes comparatively urgent.
Utility model content
For the problems referred to above, the purpose of this utility model is, provides a kind of efficiency high, safety, ensures the auto parts and components high-gloss injection mold of the de-fast material of end product quality.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of auto parts and components high-gloss injection mold, it is characterized in that, comprise upper mould core, counterdie core rod, sprue and several runners through with sprue, multiple independently die cavity is formed between upper mould core and counterdie core rod, connected by cast gate between the die cavity that each runner is corresponding with it, sprue end is provided with sprue puller, is provided with exhaust mold insert in die cavity, be provided with straight thimble below die cavity, and be provided with oblique top pin below the junction of cast gate and runner.
Described oblique top pin angle of inclination is 2 to 8 degree.
One end of described straight thimble, described oblique top pin and product into contact is round and smooth cambered surface.
Described cast gate is positioned at below die cavity, and the upper opening of cast gate is communicated with die cavity; The oblique below of runner end extends, and is communicated with the lower opening of described cast gate.
Described cast gate is cone-shaped.
Described cast gate is sub marine gate.
Described exhaust mold insert is connected with outside evacuator.
The beneficial effects of the utility model are:
1, by arranging straight thimble and oblique top pin combines, can depart from smoothly with the reinforcement of auto parts and components injecting products inside, and then making the smooth demoulding of whole injecting products;
2, by arranging exhaust mold insert in die cavity, making die cavity form vacuum state, reducing goods and there is bubble situation, realizing the high-light no-trace of auto parts and components product surface, avoid surface quality defect;
3, adopt sub marine gate, as connecting the passage of each runner with corresponding goods die cavity, making the cast gate place when ejecting goods coagulate material effectively can be separated with plastic member product, does not affect the presentation quality of auto parts and components goods.
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further illustrated.
