Description

Sintering mould of many needles location welding cup direction

Technical Field

The utility model belongs to the sintering equipment field of cup orientation is welded in the location, specifically indicates a sintering mould of cup orientation is welded in many needles location.

Background

The mold is a basic process equipment widely used in industrial production, the shape and structure of the mold determine the appearance of the product, and graphite is gradually the first choice material for mold manufacturing due to good physical and chemical properties of graphite. For some products requiring shaping and positioning in the direction of the welding cup, a graphite sintering mold capable of positioning the welding cup in a fixed direction needs to be designed. The conventional graphite mold is difficult to realize the shaping and positioning of the welding cup, so how to design the graphite sintering mold capable of adjusting the position of the welding cup into a fixed direction is a problem to be solved urgently in the product sintering process.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a graphite sintering mould with multiple needles, which can solve the technical problem that a welding cup is positioned into a fixed direction in the sintering process. In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a sintering mould of many needles location cup welding direction for sinter casing and stem, includes a plurality of moulds and lower mould, be equipped with first recess on going up the mould, be equipped with a plurality of first through-holes in the first recess, be equipped with a plurality of second recesses on the lower mould, block the casing in the second recess, be equipped with the second through-hole that quantity and first through-hole are the same in the second recess, be equipped with the counter bore on the lateral wall of the upper portion one side of second through-hole, counter bore and the coaxial setting of second through-hole non-.

Furthermore, two mutually symmetrical bulges are arranged on the inner side wall of the second groove.

Furthermore, the sintering mould comprises eighteen upper moulds, and eighteen second grooves are correspondingly arranged on the lower moulds.

Furthermore, twelve first through holes are arranged in the first groove, the first through holes are distributed in two circles concentrically, four first through holes are distributed in the inner circle uniformly, eight first through holes are distributed in the outer circle uniformly, correspondingly, twelve second through holes are arranged in the second groove, the second through holes are distributed in two circles concentrically, four second through holes are distributed in the inner circle uniformly, and eight second through holes are distributed in the outer circle uniformly.

The utility model has the advantages that:

the utility model discloses during the assembly, in being fixed in the second recess of lower mould with the casing earlier, stabilize the casing on the lower mould, guarantee that the casing can not take place to rock, place twelve stem stems in the twelve second through-holes of lower mould, place the outstanding part of cup that welds of stem in the second through-hole, other parts are shelved naturally on the counter bore, reach the bottom of lower mould. Therefore, the position of the core column welding cup can be fixed by designing the relative position of the counter bore and the second through hole, and the required requirement is met. Use the utility model discloses a behind the graphite sintering mould, can realize the position of fixed stem welding cup to the sintering goes out the electron device product that satisfies the requirement. .

Detailed Description

The present invention is further described in detail below by way of examples:

as an embodiment of the sintering mould of many needles location welding cup direction, as shown in fig. 1-7, a sintering mould of many needles location welding cup direction for sinter casing and stem, including last mould 1 and lower mould 2, upward be equipped with first recess 3 on the mould 1, be equipped with first through-hole 4 in the first recess 3, be equipped with second recess 5 on the lower mould 2, block the casing in second recess 5, be equipped with the second through-hole 6 that quantity and first through-hole 4 are the same in the second recess 5, be equipped with counter bore 7 on the lateral wall of the upper portion one side of second through-hole 6, counter bore 7 and the coaxial setting of second through-hole 6 non-.

In this embodiment, two protrusions 8 that are symmetrical to each other are disposed on the inner side wall of the second groove 5.

In this embodiment, the sintering mold includes eighteen upper molds 1, and eighteen second grooves 5 are correspondingly formed on the lower molds 2.

In this embodiment, be equipped with twelve first through-holes 4 in the first recess 3, first through-hole 4 divides the concentric equipartition of two circles, and four first through-holes 4 of inner circle equipartition, eight first through-holes 4 of outer lane equipartition, it is corresponding, be equipped with twelve second through-holes 6 in the second recess 5, second through-hole 6 divides the concentric equipartition of two circles, four second through-holes 6 of inner circle equipartition, eight second through-holes 6 of outer lane equipartition.

After the shell and the core column are placed in the lower die 2, the upper die 1 is placed on the shell, and each core column is inserted into one first through hole 4, so that the position of the core column is fixed, and the core column is prevented from being eccentric or inclined in the sintering process.
