Abstract
The invention relates to an inclined top structure of an injection mould. The inclined top structure comprises a B plate, a lower bottom plate and an inclined top mechanism, wherein the B plate and the lower bottom plate are arranged top and bottom; the inclined top mechanism is arranged above the B plate and the lower bottom plate; a vertically arranged inclined top guide block is arranged between the B plate and the lower bottom plate, the inclined top guide block is provided with a sliding chute used for the moving passing of an inclined top, and the inclined top which forms the inclined top mechanism is in sliding guide fit with an inclined top base along a horizontal direction. According to the inclined top structure of the injection mould, the inclined top guide block is arranged between the B plate and the lower bottom plate, the inclined top is wrapped by the inclined top guide block in a whole course in the moving process of the inclined top, so that the inclined top is prevented from being bent or broken, and the service life of the mould is prolonged.
Description
Technical field
The present invention relates to and relate to injection mold field, be specifically related to a kind of injection mould slanted structure.
Background technology
A kind of processing mold used when injection mold is some complex-shaped parts of batch production, by the material melted that is heated is injected die cavity by high pressure, after cooling curing, obtains formed products.Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model and cover half close and form running gate system and die cavity, and during die sinking, dynamic model is separated to take out plastic products with cover half.Some is recessed or side opening ground plastic products with side, first must carry out undercut being pushed out before, can the demoulding smoothly after extraction side core_pulling, now need to arrange side core-pulling mechanism in a mold.Side-parting core-pulling mechanism is divided into the large class of slide block and oblique top two, and oblique top is generally used for the mechanism of the inner back-off of shaped article in Design of Dies.Ramp-roof structure used at present only includes oblique top and tilted footstock, tilted footstock is fixed on Ejector Retainer Plate or thimble panel, and oblique top is empty completely between thimble panel and B plate, this ramp-roof structure, oblique top easily bends and even fractures in motion process, significantly reduces the life-span of mould.
Summary of the invention
Object of the present invention is just to provide a kind of injection mould slanted structure, and it can effectively solve the problem, and avoids oblique top bend in motion process or fracture, extends the mold use life-span.
For achieving the above object, present invention employs following technical scheme:
A kind of injection mould slanted structure, it is characterized in that: comprise the B plate and lower shoe arranged up and down, and the pitched roof mechanism that it is arranged, the oblique top guide block that vertical shape is arranged is provided with between B plate and lower shoe, oblique top guide block offers and moves for oblique top the chute passed through, the oblique top forming pitched roof mechanism forms slide-and-guide in the horizontal direction with tilted footstock and coordinates.
Concrete is: a side wall surface of oblique top guide block offers chute, oblique top is fastened in chute and both form slide-and-guide along the length direction of oblique top and coordinate, the outside wall surface that oblique top protrudes from chute offers draw-in groove in the horizontal direction, and the projection that tilted footstock is arranged is fastened in draw-in groove and both form slide-and-guide in the horizontal direction and coordinate.Tilted footstock is arranged on thimble panel or thimble floor.
The injection mould slanted structure provided in technique scheme, it arranges oblique top guide block between B plate and lower shoe, and in oblique top motion process, oblique top whole process is wrapped up by oblique top guide block, avoids oblique top bend or fracture, extends the mold use life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
In order to make objects and advantages of the present invention clearly understand, below in conjunction with embodiment, the present invention is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present invention, considered critical is not carried out to the protection domain that the present invention specifically asks.
The technical scheme that the present invention takes as shown in Figure 1, 2, a kind of injection mould slanted structure, comprise the B plate 11 and lower shoe 12 arranged up and down, and the pitched roof mechanism that it is arranged, the oblique top guide block 13 that vertical shape is arranged is provided with between B plate 11 and lower shoe 12, oblique top guide block 13 offers and moves for oblique top the chute 131 passed through, the oblique top 14 forming pitched roof mechanism forms slide-and-guide in the horizontal direction with tilted footstock 15 and coordinates.Injection mould slanted 14 structure provided in technique scheme, it arranges oblique top 14 guide block 13 between B plate 11 and lower shoe 12, and in oblique top 14 motion process, oblique top 14 whole process is wrapped up by oblique top 14 guide block 13, avoid oblique top 14 bend or fracture, extend the mold use life-span.
Concrete is operating as: a side wall surface of oblique top 14 guide block 13 offers chute 131, oblique top 14 is fastened in chute 131 and both form slide-and-guide along the length direction of oblique top 14 and coordinate, the outside wall surface that oblique top 14 protrudes from chute 131 offers draw-in groove in the horizontal direction, and the projection 151 that tilted footstock 15 is arranged is fastened in draw-in groove and both form slide-and-guide in the horizontal direction and coordinate.Tilted footstock 15 is arranged on thimble panel 16 or thimble floor 17.
B plate 11, lower shoe 12, oblique top 14 guide block 13 are fixed together, and thimble panel 16, Ejector Retainer Plate 17 and tilted footstock 15 are fixed together, and can move up and down by relatively above-mentioned part; Oblique top 14 guide block 13 has chute 131, and oblique top 14 is placed in this chute 131, and can slide along this chute 131; Tilted footstock 15 is provided with protruding 151, this projection 151 sticks in draw-in groove that oblique top 14 side is offered; Thimble panel, Ejector Retainer Plate and tilted footstock 15 together upper and lower motion time, projection 151 on tilted footstock 15 can promote oblique top 14 and move up and down, because oblique top 14 is by the constraint of oblique top 14 guide block 13 chute 131, can only slide along this chute 131, tilted footstock 15 moves left and right in oblique top 14 draw-in groove simultaneously.The original function of such maintenance oblique top 14 mechanism, and effectively can solve in traditional oblique top 14 running the problem easily bending or fracture, extend the mold use life-span.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; to know in the present invention after contents; under the premise without departing from the principles of the invention; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection scope of the present invention.
