Description
Technical Field
The utility model relates to an injection mold technical field, in particular to integral type valve needle cover mounting structure in mould.
Background
Some moulds are provided with valve needles controlled by cylinders for controlling the runner to inject glue or not. As shown in fig. 1, in the conventional structure, a flow distribution plate insert 2 is used to connect a flow passage 11 in the flow distribution plate 1, and a needle (not shown) is guided to extend and retract by a needle hub 3, and the needle hub 3 is abutted to the flow distribution plate insert 2 and has a hole 31 through which the needle passes. Because the valve needle sleeve 3 and the flow distribution plate insert 2 are two parts, the requirement on alignment precision is high, and a glue leakage channel exists between the two parts.
Therefore, it is necessary to provide a new structure to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides an integral type valve needle cover mounting structure in mould can simplify processing, reduces the hourglass and glues the risk.
The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides an integral type valve needle cover mounting structure in mould, is including installing flow distribution plate, centre gripping between upper die base and upper die plate between upper die base and the flow distribution plate cylinder device and inlaying the integral type valve needle cover of locating in the middle of the flow distribution plate, flow distribution plate has the first runner that the level set up, the upper die plate has the second runner of vertical setting, integral type valve needle cover is including the right angle pipe and the vertical running through of the first runner of intercommunication and second runner the needle pipe of right angle pipe, a needle that passes the valve needle pipe of cylinder device drive.
Specifically, the integral valve needle sleeve comprises a cylindrical portion located in the middle, and the cylindrical portion penetrates through the flow distribution plate and is in interference fit with the flow distribution plate.
Further, the integral valve needle sleeve comprises a flange at the bottom, and the flange is clamped between the flow distribution plate and the upper die plate.
Further, the integrated valve needle sleeve comprises an upper step part, and the step part abuts against the cylinder device.
Adopt above-mentioned technical scheme, the utility model discloses technical scheme's beneficial effect is:
the utility model discloses a close valve needle cover and flow distribution plate mold insert as an organic whole, simplified processing, reduced the hourglass and glued the risk.

Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 2 and 3, the utility model discloses an integral type valve needle cover mounting structure in mould, including installing flow distribution plate 6 between upper die base 4 and cope match-plate pattern 5, centre gripping cylinder device 7 between upper die base 4 and flow distribution plate 6 and inlay the integral type valve needle cover 8 of locating in the middle of flow distribution plate 6, flow distribution plate 6 has the first runner 61 that the level set up, cope match-plate pattern 5 has the second runner 51 of vertical setting, integral type valve needle cover 8 is including the right angle pipe 81 that communicates first runner 61 and second runner 51 and the vertical valve needle pipe 82 that runs through right angle pipe 81, a valve needle 71 that passes valve needle pipe 82 is driven to cylinder device 7. The integrated valve needle sleeve integrates the original valve needle sleeve and the flow distribution plate insert, has high processing precision and does not have redundant glue leakage channels. When assembled, the integral sleeve 8 is simply pressed into the manifold 6 and the right angle 81 is aligned with the first flow passage 61. Therefore, the utility model discloses a close valve needle cover and flow distribution plate mold insert as an organic whole, simplified processing, reduced the hourglass and glued the risk.
As shown in fig. 2 and 3, the unitary valve needle hub 8 includes a centrally located cylindrical portion 83, the cylindrical portion 83 passing through the diverter plate 6 and being an interference fit therewith. The cylindrical part 83 is simple to turn, and the interference fit can prevent the interface between the cylindrical part and the cylindrical part from being passed through by plastic, so that the sealing performance is ensured.
As shown in fig. 2 and 3, the integral valve needle hub 8 includes a flange 84 at the bottom, the flange 84 being clamped between the diverter plate 6 and the upper die plate 5.
As shown in fig. 2 and 3, the integral valve needle sleeve 8 includes an upper step 85, and the step 85 abuts against the cylinder device 7. The step portion 85 can be aligned as the center of the cylinder device 7, and the structure is relatively compact.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
