Abstract
The utility model discloses an eccentric-proof thin wall machining mould The eccentric-proof thin wall machining mould comprises a mould sleeve, a mould core and four positioning blocks, wherein the mould core is arranged in the mould sleeve; an extruding hole is formed in the central position of the mould sleeve; the positioning blocks are arranged on the side wall of the extruding hole and are located on the same horizontal plane; an included angle between each two positioning blocks is 90 degrees. According to the eccentric-proof thin wall machining mould, the positioning blocks in four different directions are arranged and the eccentricity of the mould sleeve is dynamically adjusted in a mould machining process; the problem that the rubber thickness of the periphery of the product is not uniform caused by mould eccentricity when the product is injection-molded by the mould is solved; the mould machining precision is improved, the structure is simple and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of processing mold, refers more particularly to a kind of thin-walled processing mold of anti-bias.
Background technology
In existing plastic injection technique, the making of the dark cavity mould of thin-walled has its uncertainty always, and the method for adjustment of the improvement of the mould structure of overall rear mold and glue position can produce very large impact to plastic product.When molding, first to consider that mold stiffness, intensity must enough bear injection pressure; Core is aspect filling in addition, how to keep good flow regime, also need to reduce as much as possible the degree of difficulty of filling and improve filling defect, be less than ± 0.01mm of product requirement wall thickness deviation, extrude the limit close to mould, so often occur in production process that core shift even wears the phenomenon of wall.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is just to provide in order to address the above problem, and improves the processing mold of the anti-bias of Mould Machining precision.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises die sleeve, core rod and four locating pieces, described core rod is arranged in die sleeve, the center of described die sleeve is provided with extrusion cavities, and described locating piece is arranged on the sidewall of described extrusion cavities and is positioned at same level, and the angle of adjacent two described locating pieces is 90 degree each other.
Particularly, on described die sleeve, be provided with locating groove in order to fixing described locating piece.
Further, described locating piece is fixedly connected with by screw thread with described die sleeve.
Particularly, described locating piece is bronze locating piece.
The beneficial effects of the utility model are:
The utility model is by arranging the locating piece of four different directions, in Mould Machining process, dynamic adjustments die sleeve bias, having solved mould can produce mould bias and cause the even problem of product surrounding glue thickness ununiformity in the time of injecting products, improve Mould Machining precision, simple in structure, enhance productivity.
Brief description of the drawings
Fig. 1 is top view of the present utility model;
Fig. 2 is side view of the present utility model;
In figure: 1-die sleeve, 2-locating piece, 3-extrusion cavities, 4-locating groove, 5-core rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As illustrated in fig. 1 and 2, the utility model comprises die sleeve 1, core rod 5 and four locating pieces, described core rod 5 is arranged in die sleeve 1, the center of described die sleeve 1 is provided with extrusion cavities 3, described locating piece 4 is arranged on the sidewall of described extrusion cavities 3 and is positioned at same level, and the angle of adjacent two described locating pieces is 90 degree each other.
As shown in Figure 1, be provided with locating groove 4 in order to fixing described locating piece 2 on described die sleeve 1, described locating piece 2 is fixedly connected with by screw thread with described die sleeve 1, and described locating piece 2 is bronze locating piece.
Operation principle of the present utility model is as follows:
In injection moulding process, die sleeve 1 is in the time carrying out injection moulding rotation, when operating personnel occur after die sleeve 1 core shift, can be in the weight of the interior increase of locating groove 4 of Membrane cover generation core shift direction or minimizing locating piece 2, the machining state of dynamic adjustments die sleeve, improve Mould Machining precision, avoid occurring that core shift even wears the phenomenon of wall.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
