Abstract
The utility model relates to a moulding mould for powder type material moulding pipe product, which is characterized in that a core column locating hole is arranged at the centre of a mould fixing plate, and locating pins are arranged on the four corners of the mould fixing plate. An outer mould is composed of two petal moulds with identical structures. Each petal mould is in a semi-cylinder shape, the two petal moulds are in fastening connection through fastening bolts, and one end of the outer mould is in welding connection with an outer mould bottom plate in fixed connection with the mould fixing plate through the locating pins. A core column composed of an upper core column and a lower core column which are in a cylindrical shape is inserted into a cylinder arranged at the centre of the outer mould, and the middle portions of the upper core column and the lower core column are wedge faces matched with each other. One-time moulding of powder dry pressing pipe products with different section shapes and without mould-pilling obliquity is achieved, the moulding rate is high, finished products are not susceptible to damage of mechanical processing, and the structural strength is remarkable higher than secondary moulding products.
Description
Technical field
The mould, particularly big L/D ratio that the present invention relates to a kind of dusty material moulding pipe fitting do not have the dry-pressing formed mould of powder of draft angle pipe fitting.
Background technology
Dry-pressing formed is that the dry powder blank is inserted in the metal die cavity, makes it become the forming method that dense green obtains required profiled member through pressing and heating.Dry-pressing formed because of its production efficiency is high, required manual work less, percent defective is low, with short production cycle, and the extrudate density of production is big, intensity is high, is fit to mass industrialized production, is widely used in the moulding of composite powder, metal dust and ceramic powders.This type powder pressing forming apparatus and method are suggested; For example proposed a kind of powder pressing forming equipment and method, in the Chinese patent of application number 200510005695.3, proposed a kind of powder pressing device and method of suppressing little muffin at Japan Patent No.2000-397967.
The powder compaction equipment that proposes in related patent U.S. Patent No. and the document is special equipment, and not only complex equipments but also equipment are applicable to the product that compact dimensions is less, can cause equipment volume huge during moulding large scale product, and the device fabrication difficulty increases greatly.The ubiquity knockout press is big during powder pressing forming, and this problem highlighted more when the problem, particularly profiled member size of demoulding difficulty was big.Powder dry-pressing pipe for big L/D ratio; In order to be beneficial to the demoulding of mould; Pipe fitting needs certain pattern draft, and requires the production of all isometrical powder dry-pressing pipe fitting of inside and outside wall for special use occasion, adopts secondary operations to remove the pattern draft of pipe fitting usually.In the existing powder compacting pertinent literature, only propose the method for powder pressing forming, do not had to propose how to solve the key issue demoulding difficulty in the powder formation of tubes.
Summary of the invention
The technical problem that solves
For fear of the weak point of prior art, the present invention proposes a kind of mould of dusty material moulding pipe fitting.
Thought of the present invention is: through employing combined type external mold and wedge shape amalgamation stem stem, and the knockout press when having reduced the pipe fitting demoulding greatly, having solved big L/D ratio does not have draft angle powder dry-pressing pipe fitting is made difficulty greatly because of knockout press problem.And this powder moulding mold simple structure is practical, does not need special powder pressing forming equipment, on general forcing press, can realize the moulding of powder pipe fitting, greatly reduces the requirement to former, has simplified powder pipe fitting compression moulding technology.

Inner chamber cross section after 2 two lobe die combination of said external mold is circle, ellipse, square, triangle and other regular polygons.
Saidly go up profile after stem stem 3 makes up with following stem stem 4, be cylindrical, triangular prism shaped, four prism type and other regular polygons according to the needs of moulding pipe fitting.
The cylinder-shaped end of said down stem stem 4 is the version that boss structure, no boss structure or other can satisfy the reliability that stem stem locatees.
The punch retainer of said punch 6 and punch pressure head for be welded to connect, threaded engagement is connected, bolt connects.
Beneficial effect
The mould of a kind of dusty material moulding pipe fitting that the present invention proposes; Beneficial effect is: the compacting of powder pipe fitting does not need special former; Common press device can meet the demands, and has simplified the production technology of large-scale no draft angle powder dry-pressing pipe fitting.Through the demoulding that separately can realize the outer wall of cylindrical element of external mold, the knockout press when having reduced the demoulding of stem stem greatly through stem stem being divided into the two parts with lozenges has made things convenient for the demoulding of powder pipe fitting, has improved production efficiency.Simultaneously through changing the cross sectional shape of external mold and stem stem moulding section; Can realize the one-shot forming of the no pattern draft powder dry-pressing pipe fitting of different cross section shape; Shaping efficiency is high, and profiled member do not destroy by machining, and structural strength is apparently higher than the secondary operations part.
