Abstract

The utility model discloses a casting die and aims to provide a faucet casting die which is simple in structure, not easy for shrinkage depression of a positioning point and capable of enabling castings to be small in integral cooling speed difference. The faucet casting die comprises an upper die (1) and a lower die (2), each of the upper die (1) and the lower die (2) is provided with a die cavity (3) matched with a workpiece, each die cavity (3) is provided with a sand core (4) in a matched manner, a sprue gate (5) is arranged at a matched position of the upper die (1) and the lower die (2), and an annular concave cavity (6) is arranged on the side wall of each die cavity (3). The faucet casting die is applied to the field of casting.

Description

A kind of tap casting mould

Technical field

The utility model relates to a kind of tap casting mould.

Background technology

In the tap industry, the product that a large amount of structure relative complex are arranged, described product must be by forging type production, casting mould is the part of casting frock, be necessity equipment that makes the cast member moulding and obtain required foundry goods, the die cavity of casting mould is generally directly injected the mobile copper water of melting in the casting that has now from the sprue gate of casting die.

A tap is arranged at present, owing to needing it is processed after this product casting, therefore, when casting, to reserve first anchor point, use for the processing location, will thickening with respect to other positions at the wall thickness of locating point position, anchor point is the meeting shrinkage depression when cooling, and copper water waters fashionable on both sides, in the difficult discharge of the air of locating point position, causes pore, the anchor point of blank needs when lacking to remove milling, described shrinkage depression and described pore will affect the quality of product, can affect the function of product when serious, and the quality of product is descended.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, anchor point to be difficult for shrinkage depression, and can make the little tap casting mould of the whole cooling velocity difference of foundry goods.

The technical scheme that the utility model adopts is: the utility model comprises upper die and lower die, be provided with the die cavity that matches with workpiece at described patrix and described counterdie, described die cavity is combined with core, described patrix and described counterdie cooperation place are provided with the sprue gate, are provided with annular cavity on the described die cavity sidewall.

The beneficial effects of the utility model are: because the utility model has adopted the design of annular cavity, and described cavity is arranged on the sidewall of the described die cavity that matches with workpiece, in casting, be provided with annular described cavity owing in the described die cavity, on the foundry goods larger area anchor point can appear then, local wall thickness is also relatively even simultaneously, so the utility model is simple in structure, anchor point is difficult for shrinkage depression, and the whole cooling velocity difference of described foundry goods is little.

Fig. 2 is decomposition texture schematic diagram of the present utility model;

Fig. 3 is the A place enlarged drawing schematic diagram of Fig. 2.

The specific embodiment

As shown in Figure 1 to Figure 3, in the present embodiment, the utility model comprises patrix 1 and counterdie 2, be provided with the die cavity 3 that matches with workpiece at described patrix 1 and described counterdie 2, described die cavity 3 is combined with core 4, described patrix 1 and described counterdie 2 cooperation places are provided with sprue gate 5, be provided with annular cavity 6 on described die cavity 3 sidewalls, in casting, annular protrusion can appear on the foundry goods, and described projection is anchor point, the topside area of described anchor point is larger, therefore be difficult for shrinkage depression, local wall thickness is also relatively even simultaneously, therefore the whole cooling velocity difference of described foundry goods is little.

The mobile metal liquid of melting is directly injected the described die cavity 3 of casting mould from the described sprue gate 5 of casting die, described metal liquid constantly enters mould, flow into described cavity 6 and to form topside area large, highly little anchor point, the described anchor point of described foundry goods is removed in scarce milling, do not affect the function of product after the processing, guaranteed the quality of product.

The utility model is applied to casting field.

Claims

1. tap casting mould, comprise patrix (1) and counterdie (2), be provided with the die cavity (3) that matches with workpiece at described patrix (1) and described counterdie (2), described die cavity (3) is combined with core (4), described patrix (1) and described counterdie (2) cooperation place are provided with sprue gate (5), it is characterized in that: be provided with annular cavity (6) on described die cavity (3) sidewall.
