Abstract
The utility model discloses a novel burr-free rubber mould which comprises a sprue bush, a main runner plate, a sub-runner plate, a mould cavity, a second sprue bush, a main runner plate, a driving plate, a driving connecting plate and a needle valve. According to the utility model, one needle valve is provided above each product in the upper mould cavity of the mould. The lower end of the needlevalve in the needle valve can penetrate the inner member of the needle valve and is closed at the runner opening for controlling the on-off of the runner opening. As the mould provided by the utilitymodel ensures the equal weight of the rubber injected into each mould of product through the simultaneously opening and closing of the needle valve. Not only is the consistency of the product ensured,but also the number of the mould cavity can be determined according to the size of the product and the size of the mould without the restriction of injection technique. The number of the rubber products is not limited, and the production efficiency is greatly increased.
Description
Technical field
The utility model relates to a kind of mould structure, particularly relates to a kind of novel non-trimming rubber mold.
Background technology
In the molding process non-trimming mould of rubber, the sizing material of cold runner part accurately degree of counting becomes the good excellent key of non-trimming mould non-trimming effect.Non-trimming mold injects glue amount major part is controlled injection glue amount by injection (mo(u)lding) machine injection measurement system now.
This method shortcoming:
1. the sizing material of the structure runner of mould distributes fully and is undertaken by the injection pressure of sprue, and the sizing material that so just causes the runner near the sprue part to distribute is many, and few away from the sizing material of the runner distribution of sprue.This method has limited the quantity of runner greatly, and then has limited the quantity of mold well number, influences production efficiency.
2. the sizing material weight that fill in every cave in the mould differs bigger, causes the product quality heterogeneity.
3. the redundant rubber stock in the runner at mould upper impression place forms useless " glue head ", and waste material is wasted the artificial of back segment again.
The utility model content
The purpose of this utility model is the novel non-trimming rubber mold that a kind of constant product quality is provided, die cavity quantity can be set relatively arbitrarily.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of novel non-trimming rubber mold, and it comprises sprue bush, main flow guidance tape, shunting guidance tape, thermal insulation board, die cavity, on sprue bush, main flow guidance tape sprue is set, and between main flow guidance tape and shunting guidance tape runner is set; It also comprises drive plate, drives connecting plate and needle valve, and described needle valve is made up of needle-valve overcoat, needle-valve internals, needle-valve, sealing ring; Described needle-valve internals are nested with in the needle-valve overcoat, are provided with sealing ring between needle-valve overcoat and needle-valve internals bottom faying face, are provided with sealing ring between needle-valve internals top and its installing plate; Described needle-valve activity is set in the needle-valve internals, and the lower end of needle-valve can pass the needle-valve internals and be enclosed on the runner mouth; Described drive plate with drive that connecting plate is fixed together and superimposed on the main flow guidance tape plane, the top ladder section of needle-valve is fixed on drive plate and also can moves up and down with the mould drive plate with driving between the connecting plate.
The lower end of described needle-valve is tapered.
After adopting such scheme, the utility model is provided with a needle valve above the product of every cave in the upper cavity of mould, and the needle-valve lower end in the needle valve can pass the needle-valve internals and be enclosed on the runner mouth, the break-make of control runner mouth.Since the utility model by needle-valve the time opening and closing guarantee being equal in weight of every cave product injection sizing material, promptly guaranteed the unanimity of product quality, and can be according to the size of product and the relative die cavity quantity of determining mould arbitrarily of size of template, and be not subjected to the restriction of injection technique, die cavity quantity can be unrestricted, improved production efficiency greatly.
Because needle-valve directly contacts with product, there be not " glue head " in rubber in the process of " curing ".
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 2 is the cutaway view of Fig. 1 along the A-A line;
Fig. 3 is the cutaway view of the utility model needle-valve overcoat;
Fig. 4 is the cutaway view of the utility model needle-valve internals;
Fig. 5 is the front view of the utility model needle-valve.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of novel non-trimming rubber mold, and it comprises sprue bush 1, main flow guidance tape 2, shunting guidance tape 3, die cavity 4, drive plate 5, drives connecting plate 6, guide pillar 7, needle valve 8, installing plate 9, thermal insulation board 10.
On sprue bush 1, main flow guidance tape 2, sprue 11 is set, between main flow guidance tape 2 and shunting guidance tape 3, runner 12 is set.
Described needle valve 8 is made up of needle-valve overcoat 81 (as shown in Figure 3), needle-valve internals 82 (as shown in Figure 4), needle-valve 83, sealing ring 84,85.Described needle-valve internals 82 are nested with in needle-valve overcoat 83, are provided with sealing ring 84 between needle-valve overcoat 81 and needle-valve internals 82 bottom faying faces, are provided with sealing ring 85 between needle-valve internals 82 tops and its installing plate (coldplate) 9; Described needle-valve 83 activities are set in the needle-valve internals 82, and the lower end 831 of needle-valve 83 is tapered, can pass needle-valve internals 82 and are enclosed on the runner mouth; Described drive plate 5 with drive that connecting plate 6 is fixed together and superimposed on main flow guidance tape 2 plane, drive plate 5 is actively socketed on the guide pillar 7 with the both sides that drive connecting plate 6, and is connected with the hydraulic system (not shown).The top ladder section 832 of needle-valve 83 (as shown in Figure 5) is fixed on drive plate 5 and drives between the connecting plate 6 and also can move up and down with mould drive plate 5.
Operation principle of the present utility model:
Hydraulic system promotes drive plate 5, and drive plate 5 moves up and down along guide pillar with driving connecting plate 6, and drive plate 5 promotes to fix the needle-valve 83 upper and lower motions on it, the flowing of the sizing material at control needle-valve 83 nozzle places 41.
Emphasis of the present utility model just is: many needle valves above the product of every cave in the upper cavity of mould.
The above, only be used for a kind of rubber mold preferred embodiment for the utility model, it can use needle valve in the different structure rubber mold, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
