The specific embodiment

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of assembling die of being convenient to the demoulding, comprise cope match-plate pattern 1, lower bolster 2, spindle hole 10, upper module 12, pedestal 5, lower module 7, injection moulding die cavity 11, side template 3, side form piece 9 and patrix guide pad 8, cope match-plate pattern upper center is shaped with the spindle hole for being connected with hydraulic cylinder guide rod, and the middle part, lower end of cope match-plate pattern is fixed with upper module; Lower bolster is arranged on the pedestal with cope match-plate pattern coaxial relative position, and the upper center of lower bolster is fixed with lower module, and cope match-plate pattern is relative with lower bolster to be fastened, and the composition surface of this upper module and lower module forms injection moulding die cavity.

Workpiece to be processed shown in the present embodiment is the special-shaped workpiece that is shaped with multistage bending, described injection moulding die cavity is the special-shaped type groove that is shaped with multistage bending, on the lower bolster of described lower module radial outside, side template is installed, on this side template, the position on corresponding matched moulds surface is provided with the side form piece of controlling workpiece side edge shape, the side that this side form piece guiding is arranged on lower module, can carry out moving radially of small distance.The radial outside of side form piece is shaped with guiding surface, the patrix guide pad that is shaped with relative guiding surface that this guiding surface coordinates upper end correspondence position to be fixedly mounted with, when cope match-plate pattern and lower bolster matched moulds, this patrix guide pad compresses side form piece, thereby guiding surface compresses driving side module radial compaction counterdie radial end face, forms side injection moulding die cavity.

In order to guarantee the matched moulds algnment accuracy of cope match-plate pattern and lower bolster, the equal symmetry in four jiaos of lower surfaces of described cope match-plate pattern is shaped with a matched moulds guide hole 16, and four jiaos of the upper surfaces of lower bolster are all shaped with a leading post 15 coordinating with matched moulds guide hole.

In order to form technique shape in injection moulding die cavity, between described counterdie and pedestal, slide-and-guide is connected, after cope match-plate pattern and lower bolster matched moulds, continuing pressurization makes lower die guiding to pressing down, four jiaos of equal slide-and-guides of described counterdie interior lower end are provided with spacing guide rod 4, what the plurality of spacing guide rod was all axially fixed in that the pedestal upper limit fixs mould presses down direction and depression distance, pedestal middle part between multiple spacing guide rods is fixed with many axial thin guide rods 6, these many corresponding lower bolster and the lower module positions of thin guide rod are all shaped with through hole, if accompanying drawing 10 is to as shown in accompanying drawing 13, counterdie continues to press down the end of thin guide rod and passes the made through hole of counterdie and stretched out by the upper surface of lower module through coaxial, when injection moulding, in the injection moulding die cavity of thin guide rod institute correspondence position, form hole or blind hole.

To form side blind hole and assurance simultaneously and complete the demoulding smoothly after injection moulding in order to form, slide bar 14 is also installed between described lower module and pedestal, the lower bolster that this slide bar is corresponding and lower module are all shaped with groove, slide bar one end is shaped with 18 slips of slide bar guide block and is inlaid in the made chute in slider block 13 upper ends, and slider block is packed on pedestal; The other end of slide bar is shaped with side opening shaping end 17 and slides and is inlaid in the injection molding resonator end surface of lower module, and when lower bolster compresses pedestal, slide bar is squeezed and is moved, and side opening shaping end stretches out the injection molding resonator end surface of lower module.

For the slip flexibility that guarantees slide bar keeps stable connection degree simultaneously, described Slide bar structure is if accompanying drawing 14 is to as shown in accompanying drawing 15, and the slide bar guide block of slide bar is the cylinder slide block structure of an evagination, and convenient installation and manufacturing cost are lower.
