Abstract

The utility model discloses a casting mould and aims to a casting mould allowing cooling speed of liquid metal to be slowed. The casting mould comprises an upper mould (1) and a lower mould (2). Each of the upper mould (1) and the lower mould (2) is provided with a mould cavity (3) matching with sand cores (4). The lower mould (2) is provided with a sprue gate (5) which is provided with a core gate (6). The core gate (6) is tightly matched with the sprue gate (5). The casting mould is applied to the field of casting.

Description

A kind of casting mould
Technical field
The utility model relates to a kind of 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, it is 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, because the structure relative complex of product and the volume of product are larger, the copper water of high temperature melting just begins cooling after entering mould, and described copper water directly contacts with described mould, described mould is metal die, the perfect heat-dissipating of metal die, so when copper water also is full of mold cavity fully, just do not begin to solidify, easily cause the quality of product bad, bring loss economically.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of casting mould that can slow down the metal liquid cooling velocity is provided.
The technical scheme that the utility model adopts is: the utility model comprises upper die and lower die, be provided with die cavity at described patrix and described counterdie, described die cavity is combined with core, be provided with the sprue gate on the described counterdie, described sprue gate is provided with the core cast gate, described core cast gate is that casting model powder and other auxiliary material are made, and described core cast gate and described sprue gate closely cooperate to prevent the metal liquid seepage.
Described core cast gate is hollow rectangular-shaped, and described rectangular-shaped because bottom surface is rectangle, and can strengthen the casting area, accelerates casting rate.
The beneficial effects of the utility model are: because the utility model has adopted the design of core cast gate, and described core cast gate and described sprue gate closely cooperate, in casting, the mobile metal liquid of melting directly injects the die cavity of casting mould from the described core cast gate of casting die, avoided high temperature metal liquid directly to contact with the casting of metals mouth, prevent that described casting of metals mouth from dispelling the heat too fast and the phenomenon with regard to having begun to solidify when metal liquid also is not full of mold cavity fully that cause, so the utility model can slow down the metal liquid cooling velocity, guaranteed the quality of product.
Description of drawings
Fig. 1 is decomposition texture schematic diagram of the present utility model;
Fig. 2 is overall structure schematic diagram of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, in the present embodiment, the utility model comprises patrix 1 and counterdie 2, be provided with die cavity 3 at described patrix 1 and described counterdie 2, described die cavity 3 is combined with core 4, be provided with sprue gate 5 on the described counterdie 2, described sprue gate 5 is provided with core cast gate 6, described core cast gate 6 closely cooperates with described sprue gate 5, described core cast gate 6 closely cooperates to prevent the metal liquid seepage with described sprue gate 5, described core cast gate 6 is that casting model powder and other auxiliary material are made, effectively avoided the described metal liquid of high temperature directly to contact with described sprue gate 5, prevented that 5 heat radiations of described sprue gate are too fast and the phenomenon with regard to having begun to solidify when described metal liquid also is not full of described die cavity 3 fully that causes.
Described core cast gate 6 is hollow rectangular-shaped, and the described rectangular-shaped design feature that combines product can be accelerated the speed that described metal liquid is full of described die cavity 3.
The mobile described metal liquid of melting is directly injected the described die cavity 3 of casting mould from the described core cast gate 6 of casting die, described metal liquid directly contacts with described core cast gate 6, effectively avoided the described metal liquid of high temperature directly to contact with described sprue gate 5, because described core cast gate 6 is that casting model powder and other auxiliary material are made, the phenomenon with regard to having begun to solidify when described metal liquid also is not full of described die cavity 3 fully that can prevent that 5 heat radiations of described sprue gate are too fast and cause, the utility model can slow down the metal liquid cooling velocity, can make described metal liquid fully be full of described die cavity 3, guarantee the quality of product.
The utility model is applied to casting field.

Claims (2)
