Detailed Description

The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.

Example 1:

as shown in fig. 1, in this embodiment, a glass bead preparing mold includes an upper mold 1, a middle mold 3, a core rod 4, a lower mold 5, and a limiting block 2 disposed outside the middle mold 3, the upper mold 1 is provided with an upper mold pillar 11, the upper mold pillar 11 is provided with an upper core rod positioning hole installed in cooperation with the core rod 4, the lower mold 5 is provided with a lower mold pillar 51, the lower mold pillar 51 is provided with a lower core rod positioning hole installed in cooperation with the core rod 4, the middle mold 3 is provided with a middle mold through hole for the upper mold pillar 11 and the lower mold pillar 51 to pass through, and the height of the limiting block 2 is equal to the sum of the length of the upper mold pillar 11, the length of the lower mold pillar 41, and the designed height of a glass bead.

When the glass beads need to be prepared, the lower die 5 is placed on the working platform, the core rod 4 is arranged in the lower core rod positioning hole, the middle die 3 is sleeved on the lower die support post 51, the dried glass powder is arranged in the middle die through hole, the upper core rod positioning hole of the upper die 1 is inserted into the upper end of the core rod 4, and the limiting block 2 is placed on the lower die 5 and beside the middle die 3. In this embodiment, the lower mandrel positioning hole is a through hole, and during pressing, a bottom pad block below the lower die 5 is provided with a through hole so that the mandrel 4 can pass through the through hole. By applying downward pressure to the upper die 1, the upper die 1 pushes the core rod 4 to move downwards until the upper die 1 is contacted with the limiting block 2, and the pressing height of the glass beads is just equal to the design height. After the glass beads are pressed, the limiting blocks 2 and the lower die 5 are taken off, the mandril 4 is clamped by using pliers, the mandril 4 is pulled out, then the rest die is integrally turned over, the upper die 1 faces downwards at the moment, the press is pulled by hand to align the edge of the middle die 3, the pressing force is gently pressed downwards, and the pressed glass beads slide out of the middle die through hole of the middle die 3. And finally, wax melting the pressed glass beads through a wax removing grate to obtain the glass bead parts required by the production of metal packaging products.

Example 2:

on the basis of the above embodiment, in this embodiment, the upper die 1 is designed to be cylindrical with a diameter of 18mm and a height of 3mm, the diameter of the upper die support 11 is the outer diameter of the glass bead/0.9, the diameter of the middle die through hole is the outer diameter of the glass bead/0.9, and the dimensional tolerance is 0.01-0.02mm smaller than the diameter of the middle die through hole; the diameter of the lower die supporting column 51 is the outer diameter of the glass bead/0.9, and the dimensional tolerance is 0.01-0.02mm smaller than the diameter of the middle die through hole; therefore, the upper die supporting column 11 and the middle die through hole, and the lower die supporting column 51 and the middle die through hole can be just installed in a matched mode, and the phenomenon that glass powder enters gaps due to the fact that too large gaps are formed and glass bead edge burrs are formed is avoided. Finally, the required glass bead part is obtained through dewaxing shrinkage molding.

The diameter of the upper mandrel positioning hole is 0.02mm larger than that of the mandrel 4, and the diameter of the lower mandrel positioning hole is 0.02mm larger than that of the mandrel 4. Therefore, the core rod 4 and the upper core rod positioning hole and the core rod 4 and the lower core rod positioning hole can be smoothly assembled, and the coaxiality of the inner diameter and the outer diameter of the glass bead can meet the design requirement.

In this example, the diameter of the core rod 4 is the inner diameter of the bead/0.75. So that the required inner diameter size can be obtained by shrinkage after the glass beads are de-waxed. The length of core rod 4 is at least 5mm greater than the height of middle die 3. The two ends of the core rod 4 are provided with round corners, so that the core rod can smoothly enter the upper core rod positioning hole and the lower core rod positioning hole.

Example 3:

on the basis of the above embodiment, in this embodiment, a chamfer is provided at one end of the middle die through hole close to the upper die 1. Through setting up the chamfer, conveniently add the glass powder into well mould through-hole and suppress.

Example 4:

in addition to the above embodiments, in the present embodiment, the bottom pad 6 is disposed below the lower die 5, and the bottom pad 6 is provided with a pad through hole through which the lower die 5 cannot pass and the mandrel 4 can smoothly pass. The lower die 5 is supported by the bottom cushion block 6, so that the core rod 4 can pass through the cushion block through hole to smoothly complete pressing work when the glass beads are pressed.

Example 5:

on the basis of the above embodiment, in this embodiment, the limiting block 2 is a semi-cylindrical shape, the middle mold 3 is cylindrical, and the inner diameter of the limiting block 2 is equal to the outer diameter of the middle mold 3. The height design of the limiting block is equal to the sum of the length of the upper die supporting column, the length of the lower die supporting column and the design height size of the glass beads. When the glass bead pressing die is used for pressing, the upper die 1 needs to be pressed to be in surface contact with the upper surface of the limiting block 2, and the height of the glass bead meets the design requirement at the moment.

Example 6:

on the basis of the above embodiment, in this embodiment, the upper die 1, the middle die 3, the core rod 4, the lower die 5 and the limiting block 2 are made of SKD11, and the hardness after quenching is HRC58-62, so that the service life of the die is ensured.

Example 7:

as shown in fig. 2, on the basis of the above embodiment, in the present embodiment, a powder scoop 7 is used to add glass powder into a through hole of a middle mold, the powder scoop 7 is designed to be of a trapezoidal structure, two counter bores 8 for containing glass powder are arranged on the powder scoop 7, and the volume of the counter bores 8 is equal to the theoretical volume of the glass beads. The powder spoon 7 is made of brass, and the brass material is soft, so that the counter bore 8 can be conveniently machined or adjusted in size.

In this embodiment, other undescribed contents are the same as those in the above embodiment, and thus are not described again.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the technical matters of the present invention all fall into the protection scope of the present invention to any simple modification and equivalent change of the above embodiments.
