Abstract
The utility model provides a mold core-free cold isostatic die, which comprises a cylindrical hollow rubber sleeve arranged on a base; at least three support frames for hard alloy bars are uniformly distributed on the periphery of the rubber sleeve; and a top cover is arranged at the upper end of the rubber sleeve. The mold core-free cold isostatic die has the beneficial effects that the deformation of the die is avoided when no rigid mold core exists inside the isostatic die; and the bending and the axial compaction of products caused by the rigid mold core are prevented.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of no core isostatic cool pressing mould.
Background technology
At present, the isostatic cool pressing mould generally can be divided into flexible core and rigid core for building according to core, when using rigid core for building, generally can well play support and styling to filler or outside pattern, and the product deflection is less.If but when using flexible core or not using interior core, in charging or forming process phenomenons such as mould bending can take place, particularly because inner no rigidity plug supports, also can produce certain compression along its length, cause product length and diameter proportion wayward, the turning processing capacity increases.
Chinese patent ZL200920090787.X has announced a kind of isostatic tooling with outside typing cover, this mould is made up of epimorph and core and the cover of finalizing the design, this device can improve reinforced uniformity, but charging finishes back typing and overlap and need take off, and there is rigid core for building inside.Chinese patent ZL96247098.8 discloses a kind of mould of being made up of the outer mould and the end plug of cylindrical structure, this mould adopts the inner flexible core, axial radial diameter ratio when uniformity of feeding in raw material in the time of can't guaranteeing to feed in raw material and compacting, the products obtained therefrom accuracy to size is relatively poor.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of no core isostatic cool pressing mould is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of no core isostatic cool pressing mould comprises a cylindrical hollow gum cover that is arranged on the base, the bracing frame of uniform at least three cemented carbide in described gum cover neighboring, and described gum cover upper end is provided with top cover.
Further, described a kind of no core isostatic cool pressing mould, wherein said bracing frame is provided with four.
Further, described a kind of no core isostatic cool pressing mould, wherein said bracing frame is close to the gum cover setting, and the internal diameter of the inner peripheral surface circle that the outer surface of bracing frame forms is suitable with described gum cover external diameter.
The beneficial effects of the utility model are mainly reflected in: this mould can make isostatic tooling prevent die deformation when no internal rigid core, and prevents the product bending and the axial compression that are caused by rigid core for building.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: structural representation of the present utility model.
Fig. 2: the utility model is along a-a direction upper section schematic diagram.
Wherein:
1 top cover, 2 bracing frames, 3 Jiao Gai
4 bases
The specific embodiment
A kind of no core isostatic cool pressing mould as shown in Figure 1 and Figure 2, comprises a cylindrical hollow gum cover 3 that is arranged on the base 4, is close to the bracing frame 2 of uniform four cemented carbide in described gum cover 3 neighborings, and gum cover 3 upper ends are provided with top cover 1.The internal diameter of the inner peripheral surface circle that the outer surface of bracing frame 2 forms is suitable with described gum cover 3 external diameters.
The top cover 1 of this mould, bracing frame 2 and base 4 detachably connect firmly.This mould can make isostatic tooling prevent die deformation when no internal rigid core, and prevents the product bending and the axial compression that cause thus.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
Claims (3)
1. no core isostatic cool pressing mould is characterized in that: comprise a cylindrical hollow gum cover that is arranged on the base, and the bracing frame of uniform at least three cemented carbide in described gum cover neighboring, described gum cover upper end is provided with top cover.
