Description

Mould for casting pot

Technical Field

The utility model relates to a pot mould technical field is cast in the pouring especially relates to a mould for casting pot.

Background

In the die-casting process of the existing die, air in a cavity between an upper die and a lower die can not be completely exhausted, so that the inner surface of a pressed pot blank is uneven, meanwhile, because the heat dissipation of the formed pot blank is slow, the pressing time is long, the temperature of the edge of the formed pot blank is often reduced firstly, the reduction speed of the temperature of the bottom is slowest, the temperature of the edge of the pot blank is reduced to the required temperature, the bottom is very hot, the die opening can cause the bottom of the pot blank to be adhered to the upper die and the lower die, the pot blank at the die-casting position can not be well demoulded, or the demoulding can be carried out, but unevenness occurs due to adhesion, so that great influence is caused; the existing die is slow in die-casting and cooling, the pot blank cannot be completely removed, the surface of the pot blank is not smooth, the die-casting efficiency is low, and meanwhile, the subsequent overall process is influenced, so that the overall production efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a mould for casting pot, can be quick cool down to the bottom of pot base, pot base shaping is effectual, does not influence whole production processes, has improved production efficiency.

The utility model discloses a realize through following technical scheme: a mold for a casting pot comprises an upper mold and a lower mold, wherein a cavity is formed in a space between the upper mold and the lower mold, a through hole leading to the cavity is formed in the horizontal position of the bottom of the upper mold, a heat conducting rod is inserted into the through hole, the lower end face of the heat conducting rod is flush with the bottom end face of the upper mold, the upper end of the heat conducting rod is located in the cavity of the upper mold, and a heat conducting hole is formed in the middle of the heat conducting rod in the axial direction.

Further, the heat conducting rod is a copper rod.

Further, the aperture of the heat conduction hole is 0.8 mm.

Furthermore, the number of the through holes is seven, and the through holes are uniformly distributed at the bottom horizontal part of the upper die.

Furthermore, the corresponding positions of the edges of the upper die and the lower die are provided with positioning pin holes, and positioning pins are arranged in the positioning pin holes.

The beneficial effects of the utility model reside in that: the utility model discloses can cool down the bottom of pot base, the mould die-casting cooling is fast, and pot base shaping is effectual, does not influence whole production processes, has improved production efficiency.

Detailed Description

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-3, a mold for a casting pot comprises an upper mold 3 and a lower mold 2, a space between the upper mold 3 and the lower mold 2 is a cavity 1, the bottom of the lower mold 2 is horizontal, the side surface is outward arc-shaped, the shape of the upper mold 3 is the same as the shape of the cavity of the lower mold 2, the bottom of the lower mold 2 is used as a main bearing part during die casting, the bottom of the lower mold 2 is thicker than the side surface, the bottom of the lower mold 2 is horizontal, a through hole 52 leading to the cavity 1 is processed at the horizontal position of the bottom of the upper mold 3, a heat conducting rod 5 is inserted into the through hole 52, the heat conducting rod 5 is a copper rod, because the heat conducting effect of copper is good, the lower end surface of the heat conducting rod 5 is flush with the bottom end surface of the upper mold 3, the upper end of the heat conducting rod 5 is located in the cavity of the upper mold 3, a heat conducting hole 51 is axially arranged at the middle position of the, therefore, liquid in the cavity 1 can not overflow from the heat conducting hole 51 in the process that the upper die 3 extrudes into the die cavity of the lower die 2, multiple experiments prove that the heat conducting hole 51 with the aperture of 0.8mm is the best choice, the aperture is enlarged, the liquid can overflow from the upper end of the heat conducting hole 51, the aperture is too small, the heat conducting effect is poor, seven through holes 52 are provided, the through holes 52 are uniformly distributed at the horizontal position of the bottom of the upper die 3, the middle through hole 52 is provided, the six through holes 52 on the periphery are positioned on the circumference of the same circle, the positioning pin holes 41 are processed at the corresponding positions of the edges of the upper die 3 and the lower die 2, the positioning pins 4 are inserted in the positioning pin holes 41, the positioning pins 4 can provide a guiding effect in the process that the upper die 3 extrudes towards the lower die 2, the direction deviation when the upper die 3 extrudes towards the lower die 2 is prevented, and positioning blocks, the positioning block is used for reserving a gap between the lower die 2 and the upper die 3, and the thickness of the positioning block can be controlled according to the thickness of a pot to be cast when the positioning block is used.

When in use: preheating the upper die and the lower die 2 at first, then pouring molten metal into the cavity of the lower die 2 from the middle position in the cavity of the lower die 2 according to the quantity, then pressing the upper die 3 into the cavity of the lower die 2, die-casting the pot blank, and spraying cold water into the upper die cavity at the same time.
