Abstract

The utility model relates to a casting mould for a flange. The casting mould is composed of an upper mould block and a lower mould block, wherein an upper core group and a lower core group which are staggered are distributed on each mould block, and each group comprises four uniformly-distributed cores; a pouring cup port is formed in the centre of the upper end of each of the upper mould block and the lower mould block, and a transversal pouring runner and a sectioned lapped-type vertical pouring runner are arranged on the both sides of each of the upper mould block and the lower mould block respectively; each vertical pouring runner is connected with two inner pouring gates, and each inner pouring gate is connected with two cores. The casting mould disclosed by the utility model is reasonable in design, and capable of effectively controlling the flow rate of molten iron at each position, increasing the utilization rate of the molten iron, decreasing the occurrence rates of various defects, and improving product quality.

Description

The flange mold

Technical field

The utility model relates to a kind of mold, specifically a kind of flange mold.

Background technology

The current common flange mold that adds the rising head pattern that directly waters as shown in Figures 3 and 4.Sprue in this mold is coherent formula, and when cast, molten iron can directly be rushed in from top the inner chamber bottom, make ingate with foundry goods, be connected the part scope larger, thereby some defects below existing: the running gate system weight, the molten iron utilization rate is not high, generally 55～60%; Molten iron pours inner chamber, trachoma, pore and sand surfing etc. easily occur, and the ingate part scope that is connected with foundry goods is large, is not easy natural separation, need knock just separable.

Summary of the invention

The purpose of this utility model is to provide a kind of technical scheme that overcomes above-mentioned defect.

The technical solution of the utility model is: a kind of flange mold is comprised of upper module and lower module.On module, be laid with two the core groups that stagger up and down, every group comprises four equally distributed cores; The upper end central authorities of upper and lower module are provided with a cup, and on its both sides, respectively are provided with the sprue of a cross gate and a segmentation bridging type.Every sprue connects two ingates, and each ingate connects two cores.

The top of described upper and lower module both sides respectively is provided with an anti-striker; Middle part in upper and lower module both sides respectively is provided with a guide.

The beneficial effects of the utility model: the utility model is reasonable in design, can effectively control the iron flow of each position, improves the utilization rate of molten iron.Significantly reduce simultaneously the incidence of all kinds of defects, improve the quality of products.

The accompanying drawing explanation

Fig. 1 is upper module schematic diagram of the present utility model.

Fig. 2 is lower module schematic diagram of the present utility model.

Fig. 3 is the upper module schematic diagram of common mold.

Fig. 4 is the lower module schematic diagram of common mold.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

As illustrated in fig. 1 and 2, the mold of flange consists of upper module 7 and lower module 8.On module, be placed with two core groups that stagger up and down, each core group comprises four equally distributed cores 9.Position in the center upper portion of upper and lower module is provided with a cup 1, pours into sand mold for molten iron.In the both sides of cup 1, respectively be provided with a cross gate 2 and the sprue communicated with cross gate 6.Every sprue 6 is the segmentation bridging type, and is connected with two ingates 3.Each ingate 3 two ends is connected with two cores 9 respectively.Molten iron enters in die cavity by ingate 3, completes the blank moulding.

Correspondingly in both sides, upper and lower module top respectively be provided with an anti-striker 4, in case module collision during the major structure type.Simultaneously, correspondingly in both sides, upper and lower module middle part respectively be provided with a guide 5, for the location of module and fixing.

The utility model is in when cast, and during the sprue of molten iron by the segmentation bridging type, its flow that can be effectively controlled, effectively improve the utilization rate of molten iron.Simultaneously, also reduced the join domain of ingate and foundry goods, the demoulding of foundry goods is more prone to.Simultaneously, the setting of anti-striker and guide, make the location of mould more accurately with stable.

The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
