Abstract
The utility model discloses a high-precision mould. The high-precision mould comprises an upper mould, a lower mould matched with the upper mould, an ejection rod hole formed in the bottom of the lower mould, positioning bulges arranged at the bottom of the upper mould in an array and positioning concave parts which are arranged on the top of the lower mould and are matched with the positioning bulges; the upper mould is provided with an air exhausting groove which is connected with a mould cavity of the lower mould and can discharge gas in the mould cavity; and the upper end of the air exhausting groove is connected with a vacuum air exhausting device. With the adoption of the mould, a positioning element does not need to be additionally arranged; in a use process, the upper mould can be directly mounted on the lower mould and the planes of the upper mould and the lower mould are fitted well; the production precision is good and the yield is good; air does not exist in the mould cavity so that air bubbles in a product can be more effectively eliminated.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of high-precision mold.
Background technology
In mould applications, existing mould relatively simple for structure is simple being made up of upper die and lower die.During work, behind the upper die and lower die matched moulds, directly be injected in the die cavity with the plastic cement of injection machine with fusion, form final product.There is following problem in this traditional mode:
1, lacks sealing device in the die cavity, have air to exist, be subjected to the influence of air drag when plastic cement flows like this in die cavity, flow difficulties.
2, because the existence of air is arranged, contain bubble in the final product that forms, product quality descends.
In industrial circle production, be seized of very big proportion at existing mold, in use, also need by setting element, could produce with mould.Yet, when being installed, setting element wastes time and energy, and very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of accurate positioning, convenience, and production precision height, the mould that the product yield is good.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of high-precision mold, comprise patrix, reach the counterdie that can cooperate with patrix, and be arranged on the jogger hole of counterdie bottom, reach the positioning convex that array is arranged on the patrix bottom, and the location depression that is installed in the counterdie top and matches with positioning convex, described patrix offers with the die cavity of counterdie and is connected, and the air discharge duct that gas in the die cavity can be discharged, described air discharge duct upper end is connected with vacuum suction device.
As optimized technical scheme, the jogger hole position of described counterdie is lined with sealing strip.
As optimized technical scheme, described patrix offers a material hole, and described air discharge duct is arranged at the both sides of material hole respectively.
As optimized technical scheme, described positioning convex is extended by patrix.
The beneficial effects of the utility model are:
By technique scheme, adopt this mould, do not need to dispose in addition setting element, directly patrix is installed to counterdie during use and gets final product, and the plane of patrix and counterdie posts, the precision of production is good, and yield is good; And because do not have air in the die cavity, can more effectively eliminate the bubble in the product.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model high-precision mold.
The specific embodiment
See also shown in Figure 1, a kind of high-precision mold of the present utility model, comprise patrix 1, reach the counterdie 2 that can cooperate with patrix 1, and be arranged on the jogger hole 3 of counterdie 2 bottoms, and array is arranged on the positioning convex 4 of patrix 1 bottom, and the location depression 5 that is installed in counterdie 2 tops and matches with positioning convex 4, described patrix 1 offers with the die cavity 6 of counterdie 2 and is connected, and the air discharge duct 7 that gas in the die cavity 6 can be discharged, and described air discharge duct 7 upper ends are connected with vacuum suction device 8.
Preferably, jogger hole 3 positions of described counterdie 2 are lined with sealing strip 9.
Preferably, described patrix 1 offers a material hole 10, and described air discharge duct 7 is arranged at the both sides of material hole 10 respectively.
Preferably, described positioning convex 4 is extended by patrix.
The beneficial effects of the utility model are:
By technique scheme, adopt this mould, do not need to dispose in addition setting element, directly patrix is installed to counterdie during use and gets final product, and the plane of patrix and counterdie posts, the precision of production is good, and yield is good; When work, with the upper die and lower die matched moulds, whole die cavity forms the state of sealing, and the recycling vacuum suction device carries out injection moulding with injection machine at last by the air in the air discharge duct extraction die cavity.Like this, the plastic cement of fusion has not just had the resistance of air when flowing in die cavity, and it is very smooth and easy to flow, and because do not have air in the die cavity, the probability that product produces bubble is very little.
The above only is the specific embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
