Abstract
The invention discloses a novel pressure casting die, and relates to the field of industrial machines. The novel pressure casting die comprises a fixed die frame, a movable die frame and a pouring system. The pouring system comprises a pouring gate, and the pouring gate is sequentially connected with a sprue runner, a transition runner and a cross runner. The movable die frame is connected with sliding blocks, and the sliding blocks are connected with guide rails. The transition runner is in a semicircular shape, and the sprue runner is in a W shape. The dimensions of products can be changed only by sliding the sliding blocks on the guide rails, and thus die waste is reduced. The W-shaped sprue runner forms a buffer area, so that the pressure to the entire die is reduced, the semicircular transition runner enables the sprue runner to form an arc-shaped buffer area, and the pressure of alloy to a die channel cavity can be relieved in the pressure casting process. The surface erosion problem caused by excessively-large pressure is solved, the service life of the die is effectively prolonged, and the novel pressure casting die is simple and ingenious in design and convenient to apply and popularize.
Description
Technical field
The present invention relates to mould manufacturing field, be specifically related to a kind of Novel pressure casting mould.
Background technology
Mould is used to the instrument of formed article, this instrument is made up of various part, different moulds is made up of different parts, it realizes the processing of article profile mainly through the change of institute's moulding material physical state, application number is CN201220022375.4, patent name is a kind of utility model patent of die casting, have and reduce seven apertures in the human head amount thus the feature improving the quality of foundry goods, but, this mould can only produce the product of a kind of profile and size, along with eliminating of product, mould also can lose value, causes very large waste; And when alloy enters, due to pressure, make mould bases bear larger pressure, alloy produces very large pressure to die channel chamber when die casting, cause the problem of the easy erosion in surface, cause the die casting life-span short.
Summary of the invention
The object of the present invention is to provide a kind of Novel pressure casting mould of long service life.
The technical scheme of technical solution problem of the present invention is: a kind of Novel pressure casting mould, comprise cover half frame, dynamic model frame and running gate system, described running gate system comprises into cast gate, described enter cast gate be connected with sprue, transition road and cross gate in turn, described enter the area of cast gate be 12-21 square centimeters, described dynamic model frame is connected with slide block, and described slide block is connected with guide rail, described transition road is semicircle shape, described in enter cast gate be " W " font.
As further improvement, the quantity of described slide block is four.
As further improvement, described in enter cast gate and be provided with sprue bush.
As further improvement, described sprue bush is Teflon Fiber Materials.
As further improvement, the thickness of described sprue bush is 4-9mm.
Beneficial effect: in the present invention, dynamic model frame is connected with slide block, slide block is connected with guide rail, only need by slide on rails slide block, change dynamic model frame, the change to product size can be reached, add the function of mould, decrease the situation of mould waste, " C font enter cast gate, define buffering area, decrease the pressure to whole mould, the transition road of semicircle shape makes to which form arc buffering district, the pressure of alloy to die channel chamber can be alleviated when die casting, solve the excessive sheet erosion problem caused of pressure, effectively raise the mold use life-span, sprue bush is Teflon Fiber Materials, has the feature of high temperature high voltage resistant, effectively protects into cast gate.
Accompanying drawing explanation
Fig. 1 is top view of the present invention.
Fig. 2 is the front view of running gate system in the present invention.
Wherein: 1-guide rail, 2--cover half frame, 3-dynamic model frame, 4-running gate system, 5-slide block,
6-sprue bush, 7-enter cast gate, 8-cross gate, 9-sprue, 10-transition road.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.As depicted in figs. 1 and 2: a kind of Novel pressure casting mould, comprise cover half frame 2, dynamic model frame 3 and running gate system 4, described running gate system 4 comprises into cast gate 7, described enter cast gate 7 be connected with sprue 9 in turn, transition road 10 and cross gate 8, described enter the area of cast gate 7 be 12-21 square centimeters, described dynamic model frame 3 is connected with slide block 5, described slide block 5 is connected with leads 1 rail, described transition road 10 is semicircle shape, described enter cast gate 7 be " W " font, only need by slide on rails slide block, change dynamic model frame, the change to product size can be reached, add the function of mould, decrease the situation of mould waste, " W " font enter cast gate, define buffering area, decrease the pressure to whole mould, the transition road of semicircle shape makes to which form arc buffering district, the pressure of alloy to die channel chamber can be alleviated when die casting, solve the excessive sheet erosion problem caused of pressure, effectively raise the mold use life-span.
Enter cast gate 7 described in it should be noted that and be provided with sprue bush 6, described sprue bush 6 is Teflon Fiber Materials, and the thickness of described sprue bush 6 is 4-9mm, has the feature of high temperature high voltage resistant, effectively protects into cast gate.
In the present embodiment, the quantity of described slide block 5 is four.
Based on above-mentioned, slide block is connected with guide rail, only need by slide on rails slide block, the change to product size can be reached, decrease the situation of mould waste, " W " font enter cast gate, define buffering area, decrease the pressure to whole mould, the transition road of semicircle shape makes to which form arc buffering district, can alleviate the pressure of alloy to die channel chamber when die casting, solve the excessive sheet erosion problem caused of pressure, effectively raise the mold use life-span, this skillful in design, is worthy to be popularized.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
