Description

A kind of core shooter for making gate valve core
Technical field
This utility model relates to a kind of core shooter, especially a kind of core shooter for making gate valve core.
Background technology
At present, when producing gate valve, it is usually and core is placed in casting die, then in mould, liquid metal is poured into, core is made to be surrounded by liquid metal, after liquid metal cools down, just the strainer valve of primary is formed, therefore, core, except identical with the moulding within gate valve, also requires have higher intensity, breathability, deformability and collapsibility, and the making of core is usually and is completed by core shooter, core shooter is to utilize compression air that molding sand is injected sandbox pre-consolidation equably, then applies pressure again and carries out compacting.Conventional gate valve core shooter includes pedestal, upper cavity, lower mode cavity, penetrates sand device, when upper and lower film chamber is combined, penetrates sand device and injects in die cavity by molding sand, and then the molding sand in die cavity is compacted, and namely forms gate valve core.But, the gate valve core produced by existing core shooter is mostly based on solid, and intensity and breathability are poor, and during fabrication, required molding sand is relatively more, and cost of manufacture is relatively big, and the price of gained core is also higher.
Utility model content
For the problems referred to above, this utility model provides a kind of core shooter for making gate valve core, and its technical scheme adopted is as follows:
A kind of core shooter for making gate valve core, including pedestal, the left of pedestal is provided with penetrates sand device, lower mode cavity it is provided with in the middle part of pedestal, the corner place of pedestal is provided with guide pillar, guide pillar is provided with upper cavity, upper cavity can slide up and down along guide pillar, upper cavity is connected above power set, the front of described lower mode cavity, rear, right are each provided with an electrical bar, and electrical bar is connected to cylinder, under the drive of cylinder, electrical bar can pass in and out lower mode cavity, and the guide groove being provided with correspondence in lower mode cavity passes in and out for electrical bar.Electrical bar in lower mode cavity, molding sand in die cavity can be heated sintering, molding sand can become finer and close under high temperature action, intensity is bigger, additionally, due to the existence of electrical bar, the gate valve core formed in die cavity is hollow-core construction, not only breathability is strong, and required molding sand is few, is greatly saved manufacturing cost.
Further, described in penetrate sand device and include sand tank, sand-shooting head, sand-shooting head is positioned at below sand tank, and sand-shooting head is provided with sand-spraying hole, and the side of lower mode cavity is provided with and corresponding with sand-spraying hole enters sand hole.
By the realization of technique scheme, the gate valve core reality intensity that the provided core shooter of this utility model is produced is big, breathability strong, and manufacturing cost is little, and price is low.
Accompanying drawing explanation
This utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is provided the front view of core shooter for making gate valve core for this utility model;
Fig. 2 is the sectional view in Fig. 1 along A-A direction.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of core shooter for making gate valve core, including pedestal 1, the left of pedestal 1 is provided with penetrates sand device, lower mode cavity 3 it is provided with in the middle part of pedestal 1, the corner place of pedestal 1 is provided with guide pillar 4, guide pillar 4 is provided with upper cavity 5, upper cavity 5 can slide up and down along guide pillar 4, upper cavity 5 is connected above power set 6, the front of lower mode cavity 3, rear, right is each provided with an electrical bar 7, electrical bar 7 is connected to cylinder 8, under the drive of cylinder 8, electrical bar 7 can pass in and out lower mode cavity 3, the guide groove 9 being provided with correspondence in lower mode cavity 3 passes in and out for electrical bar 7;Penetrating sand device and include sand tank 21, sand-shooting head 22, sand-shooting head 22 is positioned at below sand tank 21, and sand-shooting head 22 is provided with sand-spraying hole, and the side of lower mode cavity 3 is provided with and corresponding with sand-spraying hole enters sand hole 31.This kind of core shooter is in use, upper cavity 5 is combined with lower mode cavity 3 under the drive of power set 6, simultaneously, each electrical bar 7 enters lower mode cavity 3 under the drive of cylinder 8, what then lower mode cavity 3 side injected by molding sand by the sand-spraying hole on sand-shooting head 22 enters in sand hole 31, electrical bar 7 in lower mode cavity 3, molding sand can be heated sintering, molding sand can become finer and close under high temperature action, intensity is bigger, in addition, existence due to electrical bar 7, the gate valve core formed in die cavity is hollow-core construction, not only breathability is strong, and required molding sand is few, it is greatly saved manufacturing cost;After gate valve core molding, upper cavity 5 slip up, upper and lower die cavity is opened, and finally takes out gate valve core, completes.
Above in conjunction with accompanying drawing, this utility model is exemplarily described; obvious this utility model implements and is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model design carries out with technical scheme; or not improved design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
