Abstract
A lift-out cushion block structure for an injection mold is composed of a movable template (1), a thimble (2), a thimble plate (3), a thimble panel (4), a support block compound plate (5), a lift-out cushion block (6), and fastening screws (7), wherein the thimble (2) is arranged under the movable template (1); the thimble (2) is fixed onto the thimble plate (3); the thimble panel (4) is fixed onto the block compound plate (5). The lift-out cushion block structure is characterized in that the lift-out cushion block is further arranged on the support block compound plate (5), and is connected with the thimble panel (4) through the screws (7). According to the utility model, the lift-out cushion block is arranged in the lift-out position of the thimble panel; during the injection process, a lift-out roller of an injection molding machine does not act directly on the thimble panel, but strikes the lift-out cushion block, so that the lift-out cushion block can be replaced later conveniently, and balancing and smooth lift-out of a mold part during the demolding process can be realized; the mold lift-out cushion block is simple in structure, feasible, stable and reliable during work, simple in manufacturing technology, and low in cost.
Description
Technical field
The utility model relates to a kind of injection mold, especially the ejector pad block structure in injection mold mould emptier.
Background technology
Injection molded is the main method of now forming thermoplastic, and therefore range of application is very extensive.Injection molded is that plastic raw materials is put into barrel, through heat fused, make it to become full-bodied melt, with plunger or screw rod as pressurizing tool, make melt inject the die cavity of mould with higher pressure by nozzle, through supercooling, solidification stages, then from mould, deviate from, become plastic products.
Plastic must take out it by mechanical mode after solidifying in die cavity from die cavity, and this action will be completed by mould emptier.Irrational mould emptier has a great impact the quality of plastic, and the geometry of plastic is also ever-changing, so must adopt the most effective and optimal stripping means.For the mould of die life more than 100,000 moulds, ejector retainner plate is constantly subject to injection machine and ejects the collision repeatedly of rod, long-term impact, finally cause ejector retainner plate buckling deformation, causing mould ejection imbalance, there is cracking in plastic, smoothly the injection defect such as the demoulding.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of ejector pad block structure of injection mold, to be provided with and to eject cushion block ejecting on position of thimble panel, make in injection moulding process, the rod that ejects of injection machine is not to act directly on thimble panel, ejects on cushion block but impinge upon.
The technical solution of the utility model is to realize in the following manner: a kind of ejector pad block structure of injection mold, by moving platen, thimble, ejector retainner plate, thimble panel, mould pin compound plate, eject cushion block, hold-down screw forms, the below of moving platen is provided with thimble, thimble is fixed on ejector retainner plate, mould pin compound plate is fixed with thimble panel, it is characterized in that: described mould pin compound plate is also provided with and ejects cushion block, eject cushion block and thimble panel is connected by screw.
Described eject cushion block with thimble panel diameter with highly consistent, conveniently eject cushion block and change.
The utility model structure, install and eject cushion block ejecting on position of thimble panel, in injection moulding process, the rod that ejects of injection machine is not on direct acting thimble panel, eject on cushion block but impinge upon, conveniently eject the cushion block later stage change, can realize ejection phase plastic balance, eject smoothly.Meet plastic product to structural and requirement aesthetic appearance.Mould ejection cushion block structure is simple, and working stability is reliable, and manufacturing process is simple, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of mould pin compound plate.
The specific embodiment
Known by Fig. 1, a kind of ejector pad block structure of injection mold, by moving platen 1, thimble 2, ejector retainner plate 3, thimble panel 4, mould pin compound plate 5, eject cushion block 6, hold-down screw 7 forms.The below of moving platen 1 is provided with thimble 2, and thimble 2 is fixed on ejector retainner plate 3, and mould pin compound plate 5 is fixed with thimble panel 4, it is characterized in that: described mould pin compound plate 5 is also provided with and ejects cushion block 6, ejects cushion block 6 and is connected by screw 7 with thimble panel 4.Described eject cushion block 6 with thimble panel 4 diameters with highly consistent, conveniently eject cushion block 6 and change.
Being known by Fig. 2, is the top view of mould pin compound plate.Mould pin compound plate 5 is provided with four installations and ejects the through hole of cushion block 6, and it is fixing that mould pin compound plate 5 ejects cushion block 6 use hold-down screws 7.
In injection moulding production process, mould matched moulds, start injection moulding, pressurize, cooling, in injection moulding production ejection phase, the rod that ejects of injection machine is not on direct acting thimble panel 4, eject on cushion block 6 but impinge upon, the manufactured materials that ejects cushion block 6 is Cr12, and heat treatment hardness requires to reach 48～50HRC.Like this, in the stage that ejects of injection moulding process, can make plastic product balance, eject smoothly, meet plastic product to structural and requirement aesthetic appearance.Mould ejection cushion block 6 is simple for structure, and working stability is reliable, and manufacturing process is simple, with low cost.
Claims (2)
1. the ejector pad block structure of an injection mold, by moving platen (1), thimble (2), ejector retainner plate (3), thimble panel (4), mould pin compound plate (5), eject cushion block (6), hold-down screw (7) forms, the below of moving platen (1) is provided with thimble (2), thimble (2) is fixed on ejector retainner plate (3), mould pin compound plate (5) is fixed with thimble panel (4), it is characterized in that: described mould pin compound plate (5) is also provided with and ejects cushion block (6), eject cushion block (6) and be connected by screw (7) with thimble panel (4).
2. the ejector pad block structure of a kind of injection mold according to claim 1, is characterized in that: described eject cushion block (6) with thimble panel (4) diameter with highly consistent, conveniently eject cushion block (6) and change.
