Description

A kind of special casting mould of castingin type compression roller

Technical field

The utility model is related to a kind of casting mould, the special casting mould of more particularly to a kind of castingin type compression roller.

Background technology

Compression roller is an important part in manufacture cement process, and former traditional compression roller is all added using forging processing The form of built-up welding, and this compression roller wearability is poor, needs constantly to repair built-up welding during use, service life is short, makes Into stopping, the kiln time is longer, so as to influence manufacturing schedule, and need to spend substantial amounts of human and material resources.

Utility model content

The utility model, can mainly solving the technical problems that provide a kind of castingin type compression roller special casting mould It is convenient, fast, efficiently prepare castingin type compression roller, and obtained compression roller quality is high, especially wearability pole By force, service life is long.

In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of castingin type extruding is provided The special casting mould of roller, including：Upper die and lower die；

The center of the upper mould offers sprue gate, and is connected with a plurality of runner below the sprue gate, in institute State inside mould and be further opened with multiple feeding roads positioned at each runner outside；

Inner chamber is offered in the lower mould, the center of the inner chamber is fixed with loam core, the edge of the inner chamber fixed peace Equipped with multiple abrasion-proof sticks；

The lower port in each runner and the feeding road with the intracavity inter-connection.

In one preferred embodiment of the utility model, the material of the abrasion-proof stick is ZG45, further improves entirety Anti-wear performance.

In one preferred embodiment of the utility model, the abrasion-proof stick is fixed by way of welding iron nail, energy Enough ensure that abrasion-proof stick does not drop during casting.

The beneficial effects of the utility model are：A kind of special casting mould of castingin type compression roller of the utility model is on the one hand Abrasion-proof stick is fixed using in inner chamber surrounding edge, so that castingin has multiple wear-resisting on the working face of compression roller after casting complete Rod, so that compression roller parent protection abrasion-proof stick is not fallen off during use, abrasion-proof stick protects compression roller parent and not ground Damage, so as to improve significantly anti-wear performance, service life is long；On the other hand row is repeatedly kicked into using the multiple runners in lower point of a sprue gate Cast, efficiently reduces impulse force, so as to prevent in casting process due to flow under conditions of ensureing that poring rate is constant And impulsive force too greatly breaks up each abrasion-proof stick, improves product qualification rate.

Brief description of the drawings

Fig. 1 is a kind of structural representation of the special casting mould of castingin type compression roller of the utility model；

Fig. 2 is the top view of upper mould in Fig. 1；

Fig. 3 is the top view of lower mould in Fig. 1；

The mark of each part is as follows in accompanying drawing：1st, upper mould, 2, lower mould, 11, sprue gate, 12, runner, 13, feeding road, 21st, inner chamber, 22, abrasion-proof stick, 23, loam core.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite Define.

Referring to Fig. 1, the utility model embodiment includes：

A kind of special casting mould of castingin type compression roller, including：Upper mould 1 and lower mould 2；

As shown in Fig. 2 the center of the upper mould 1 offers sprue gate 11, and it is connected with the lower section at the sprue gate 11 A plurality of runner 12, the inside of mould 1 and multiple feeding roads 13 are further opened with described positioned at each outside of runner 12；

As shown in figure 3, offering inner chamber 21 in the lower mould 2, the center of the inner chamber 21 is fixed with loam core 23, described interior Multiple abrasion-proof sticks 22 are installed with the edge of chamber 21；

The lower port in each runner 12 and the feeding road 13 is connected with the inner chamber 21.

Wherein, the material of the abrasion-proof stick 22 is ZG45, further improves overall anti-wear performance.

The abrasion-proof stick 22 is fixed by way of welding iron nail, ensure that abrasion-proof stick 22 during casting Do not drop.

Prior art is different from, a kind of workflow of the special casting mould of castingin type compression roller of the utility model is： Molten metal after melting is injected at the sprue gate 11 of upper mould 1, subsequent molten metal is flowed into lower mould 2 along each runner 12 In chamber 21, due to the effect of runner 12 so that can efficiently reduce impulse force under conditions of ensureing that poring rate is constant, So as to prevent in casting process because flow and impulsive force are too big and break up each abrasion-proof stick 22, it is ensured that prepare the matter of product Amount, after metal flows into inner chamber 21, molten metal is filled rapidly, and covers each abrasion-proof stick 22, until molten metal fills up feeding road 13 After stop casting of molten metal, then treat its cooling and mould unloading, and the loam core 23 of product center is knocked out, you can obtain castingin type extruding Roller, and the obtained castingin type compression roller possesses extremely strong anti-wear performance, service life is long.

Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical fields, are similarly included in scope of patent protection of the present utility model.
