Abstract
The invention discloses a valve needle fixing column for an overall lever hot nozzle. The valve needle fixing column comprises a column body, wherein a groove is formed in the middle part of the column body; a circular valve needle hole is formed in the middle of the bottom of the column body; the groove is matched with a ball bearing on a lever; the circular valve needle hole is used for mounting a valve needle. According to the valve needle fixing column for the overall lever hot nozzle, the groove is formed in the middle of the column body, and the circular valve needle hole is formed in the middle of the bottom of the column body; the groove is matched with the ball bearing on the lever, and the circular valve needle hole is used for mounting the valve needle; when moving, the lever drives the column body to move up and down, and the circular valve needle hole can prevent the valve needle from being deflected towards one side; the moving resistance of the lever is low, and the friction force is low, so that the valve needle cannot be locked or broken.
Description
Technical field
The present invention relates to a kind of Integral lever hot mouth needle fixed leg, belong to injection mould component technical field.
Background technology
TOP-TIP carrys out injection mold by carrying out heating in the cavity that the plastics of thawing is injected into mould, it has shortening product molding cycle, raise the efficiency, save plastic raw materials, reduce waste product, improve the quality of products, unskilled workman's sequence after eliminating, be conducive to the production automation, expand the plurality of advantages such as injection molding process range of application; TOP-TIP generally comprises hot runner manifold and hot mouth etc., hot mouth needs the output being realized material by needle, and old structure adopts lever one end open to coordinate with needle, and such needle and the lever frictional force when motion state is large, needle is easily toward inclined on one side, and needle is stuck or fracture easily.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose that a kind of frictional force is little, the Integral lever hot mouth needle fixed leg of needle not easily stuck or fracture.
Technical solution of the present invention is achieved in that a kind of Integral lever hot mouth needle fixed leg, comprises cylinder; Offer groove in the middle part of described cylinder, in the middle of bottom, be provided with needle circular hole; Described groove for the ball-bearing fit on lever; Described needle circular hole is for installing needle.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of Integral lever of the present invention hot mouth needle fixed leg, by offering groove in the middle part of cylinder, bottom in the middle of offers needle circular hole, groove for the ball-bearing fit on lever, needle circular hole is for installing needle, when lever motion, drive cylinder moves up and down, and needle circular hole can prevent needle toward inclined, and lever motion resistance is little, frictional force is little, and needle can not stuck or fracture.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of a kind of Integral lever of the present invention hot mouth needle fixed leg;
Accompanying drawing 2 is the using state figure of a kind of Integral lever of the present invention hot mouth needle fixed leg;
Wherein: 1, cylinder; 2, groove; 3, needle circular hole; 4, lever, 5, ball bearing; 6, needle; 7, needle fixed leg.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
As accompanying drawing 1,2 is depicted as a kind of Integral lever of the present invention hot mouth needle fixed leg, comprise cylinder 1; Offer groove 2 in the middle part of described cylinder 1, in the middle of bottom, be provided with needle circular hole 3; Described groove 2 is for coordinating with the ball bearing 5 on lever 4; Described needle circular hole 3 is for installing needle 6.
The present invention by offering groove 2 in the middle part of cylinder 1, needle circular hole 3 is offered in the middle of bottom, groove 2 is for coordinating with the ball bearing 5 on lever 4, needle circular hole 3, for installing needle 6, when lever 4 moves, drives cylinder 1 to move up and down, needle circular hole 3 can prevent needle 6 toward inclined on one side, lever 4 resistance of motion is little, and frictional force is little, and needle 6 can not stuck or fracture.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
