Abstract
The utility model discloses an injection molding die, which comprises a fixed die plate, a movable die plate which is opposite to the fixed die plate, a fixed die kernel which is matched with an opening on the fixed die plate, and a movable die kernel which is matched with an opening on the movable die plate and is opposite to the fixed die kernel; a mold cavity is formed between the end surface of the movable die kernel and the end surface of the fixed mold kernel; either the fixed die kernel or the movable die kernel is provided with a plurality of fine positioning lug bosses, and the rest one is provided with a plurality of positioning holes which are matched with a plurality of fine positioning lug bosses. The assembly precision degree between the fixed die plate and the movable die plate of the die is high.
Description
Technical field
The utility model relates to a kind of die device.
Background technology
When using die device to make profiled member, the machining accuracy of profiled member mainly is subjected to the manufacturing of mould and the influence of assembly precision.So the assembly precision that improves mould is one of the important means that improves the precision of profiled member.
Mould normally positions by alignment pin.The injection forming mold of prior art comprises a solid plate and a moving platen, and solid plate and moving platen are oppositely arranged, and solid plate cooperates the back to form a die cavity for the moulding material moulding with moving platen.Moving platen is provided with a plurality of alignment pins, and solid plate is provided with the locating hole that alignment pin a plurality of and on the moving platen matches, during matched moulds, described alignment pin matches with described locating hole, improves the assembly precision and the accuracy of manufacture between solid plate and the moving platen.Usually, alignment pin is four edges that are arranged at moving platen symmetrically, and so the mould that is provided with is when assembling, and alignment pin is not good to the locating effect between moving, the solid plate.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of injection forming mold is provided, the solid plate of this mould and the assembly precision height between the moving platen.
For solving above technical problem, the utility model is taked following technical scheme:
A kind of injection forming mold, comprise solid plate, the moving platen relative with solid plate, be matched with the opening on the solid plate cover half benevolence, be matched with the opening of moving platen and the mavable module core relative with cover half benevolence, behind the matched moulds, form die cavity between the end face of the end face of mavable module core and cover half benevolence, parts in cover half benevolence, two parts of mavable module core are provided with a plurality of fine positioning projections, and another parts in two parts are provided with the locating hole that matches with a plurality of fine positioning projections.
Preferred version of the present utility model is: a plurality of described fine positioning projections are set on described mavable module core.
Described fine positioning projection has four, and these four fine positioning projections lay respectively on four angles of mavable module core.
Because the employing of technique scheme, the utility model has following advantage compared to existing technology:
Because mavable module core and cover half benevolence are to match with opening on moving platen and the solid plate respectively, between mavable module core and the cover half benevolence fine positioning system is set, during matched moulds, concavo-convex precision-fit makes the assembly precision height between solid plate and the moving platen between mavable module core and the cover half benevolence.
Description of drawings

Fig. 2 is the front view of solid plate of the present utility model;
Wherein, 1, solid plate; 2, moving platen; 3, cover half benevolence; 4, mavable module core; 6, fine positioning projection; 7, locating hole; 10, first opening; 20, second opening.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
As depicted in figs. 1 and 2, injection forming mold according to present embodiment mainly comprises solid plate 1, moving platen 2, solid plate 1 is oppositely arranged with moving platen 2, solid plate 1 has first opening 10 that is positioned at the middle part, moving platen 2 has second opening 20 that is positioned at the middle part, behind the matched moulds, form the part that die cavity 3, the first openings 10 and second opening 20 have constituted die cavity between solid plate 1 and the moving platen 2.
This injection forming mold also comprises the cover half benevolence 3 that matches with first opening 10 that is fixedly installed on the described solid plate 1, is fixedly installed on the mavable module core 4 that matches with second opening on the described moving platen 2, on four angles of mavable module core 4, protrude and be provided with fine positioning projection 6, offer locating hole 7 in the relevant position of cover half benevolence 3, during matched moulds, fine positioning projection 6 matches with locating hole 7, when making assembling solid plate 1 and moving platen 2, can locate more accurately.
Because fine positioning projection 6 is arranged on the mavable module core 4, fine positioning protrusion distance die cavity is near, moving like this, solid plate carries out coarse positioning by the pin-and-hole that is arranged on edge, carry out fine positioning by near the fine positioning system that is positioned at the die cavity, locating effect is better, the positioning accuracy height between solid plate 1 and the moving platen 2.
Claims (3)
1, a kind of injection forming mold, comprise solid plate (1), the moving platen (2) relative with described solid plate (1), be matched with the cover half benevolence (3) of the opening of described solid plate (1), be matched with the opening of described moving platen (2) and the mavable module core (4) relative with described cover half benevolence (3), behind the matched moulds, form die cavity between the end face of the end face of described mavable module core (4) and described cover half benevolence (3), it is characterized in that: described cover half benevolence (3), parts in (4) two parts of described mavable module core are provided with a plurality of fine positioning projections (6), and another parts in two parts are provided with the locating hole (7) that matches with a plurality of described fine positioning projections (6).
