Abstract
The invention discloses a casting system for a multi-cavity mould. The casting system comprises a main flow passage, wherein the main flow passage is connected with a flow distribution plate; a plurality of sub flow passages are uniformly distributed on the flow distribution plate; a first gate and a second gate which are vertical to the flow distribution plate are arranged below the sub flow passages; the first gate is close to the main flow passage; the second gate is distributed on the outer side of the first gate; the first gate and the second gate are annularly distributed around the main flow passage; the bottoms of the first gate and the second gate are provided with circular sprue gates. Through the manner, the batch production of a plurality of products can be realized, the casting force is uniform, and thus the product quality is improved without damaging the mould.
Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of running gate system of multi-cavity mold.
Background technology
A mould with multi-cavities of the prior art, generally adopt a plurality of die cavities directly to be connected, and the mode of production that the plastic cement melt is poured into a mould to each die cavity one by one by sprue easily causes the inhomogeneous of each product cast quality, affects product quality.And, because the plastic cement melt-flow needs the external world to give larger injection dynamics through each die cavity, easily mould is caused to certain damage.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of running gate system of multi-cavity mold, can produce a plurality of products in batches, and the cast power is even, and product quality is improved, and can not cause damage to mould.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of running gate system of multi-cavity mold is provided, comprise: sprue, described sprue connects flow distribution plate, be evenly distributed with some runners on described flow distribution plate, described runner has first gate vertical with described flow distribution plate and the second gate, described the first gate is near described sprue, described the second gate is distributed in the described first gate outside, described the first gate and described the second gate are distributed in around described sprue all ringwise, and the bottom of described the first gate and described the second gate all is provided with circular sprue gate.
In a preferred embodiment of the present invention, described the first gate and described the second gate distribute all ringwise, around the first all gates, are provided with the first cooling circuit, around the second all gates, are provided with the second cooling circuit.
The invention has the beneficial effects as follows: the running gate system of multi-cavity mold of the present invention, comprise sprue, described sprue connects flow distribution plate, be evenly distributed with some runners on described flow distribution plate, described runner has first gate vertical with described flow distribution plate and the second gate, described the first gate is near described sprue, described the second gate is distributed in the described first gate outside, described the first gate and described the second gate are distributed in around described sprue all ringwise, the bottom of described the first gate and described the second gate all is provided with circular sprue gate, the plastic cement melt that leads to the first gate and the second gate by sprue speed is uniformly poured into a mould, the cast dynamics is identical, can not produce the damage to mould because of instantaneous larger injection dynamics, can pour into a mould the product that a plurality of qualities are identical simultaneously, improved production efficiency.
The accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of a preferred embodiment of the present invention;
Fig. 2 is the plan structure schematic diagram of a preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, sprue, 2, flow distribution plate, the 3, first gate, the 4, second gate, 5, sprue gate, the 6, first cooling circuit, the 7, second cooling circuit, 8, runner.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of running gate system of multi-cavity mold, comprise: sprue 1, sprue 1 connects flow distribution plate 2, be evenly distributed with six runners 8 on flow distribution plate 2, runner 8 has first gate 3 vertical with flow distribution plate and the second gate 4, the first gates 3 are distributed in first gate 3 outsides near sprue 1, the second gate 4, the first gate 3 and the second gate 4 are distributed in around sprue 1 all ringwise, and the bottom of the first gate 3 and the second gate 4 all is provided with circular sprue gate 5.
Around the first gate 3 and the second gate 4, correspondence is distributed with the first cooling circuit 5 and the second cooling circuit 7, the first gate 5 is near sprue 1, the plastic cement melt is full of the speed of die cavity faster than the second gate 4, controlling by intellectuality the product that can first pour into a mould the first gate 3 carries out cooling, the product of opening again 7 pairs of the second gate 4 cast of the second cooling circuit after the second gate 4 is poured carries out cooling, can improve the efficiency of production like this, improve the quality of product.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
