Abstract
The utility model discloses a die-casting mold of a flowmeter casing, which is formed by the combination of a movable mold and a fixed mold, wherein the parting face of the movable mold is provided with a concave cavity to form a die cavity of the movable mold, a movable mold core is arranged in the cavity, the parting face of the fixed mold is provided with a concave cavity to form a die cavity of the fixed mold, a fixed mold core is arranged in the cavity, and a plurality of core-pulling slide blocks are installed on the movable mold. A pouring system is respectively arranged on the movable mold and the fixed mold and comprises a pouring channel and a pouring gate, wherein the pouring channels comprise an annular pouring channel on the movable mold and an annular pouring channel on the fixed mold. An overflow groove is respectively arranged on the parting faces of the movable mold and the fixed mold. The utility model reduces air holes inside parts greatly, lowers the loss of the mold and enhances the qualification rate of a product.
Description
Technical field
The utility model belongs to casting field, relates to a kind of flowmeter shell die casting specifically.
Background technology
In the technology of die casting flowmeter shell, the size and the performance of part there is very high requirement, so during this part of die casting, to the strict control of pore number needs.Die design schemes of the prior art as depicted in figs. 1 and 2, running channel adopts the side running channel on the cover half, when therefore molten metal flows into die cavity inside, can find out obviously that liquid flows directly to the big core of 1,3,4 cylinders, forms bigger impact, causing molten metal to scatter splashes, liquid stream is disorderly, and gas is discharged difficulty, and the part internal porosity of die casting is more.In addition, liquid stream is big to the impulsive force of mould, makes mould be easy to produce erosion and sticking aluminium phenomenon, thereby increases the cost of maintenance mould and shorten die life.
Summary of the invention
The purpose of this utility model is in order to solve the problems referred to above that original mould exists, a kind of novel flowmeter shell mould to be provided.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of flowmeter shell die casting, be involutory by dynamic model and cover half and form, the dynamic model die joint is opened cavity and is formed the dynamic model die cavity and be provided with moving-mould-core in the chamber, the cover half die joint leaves cavity and forms the cover half die cavity and be provided with the cover half core in the chamber, and some slide blocks of loosing core are installed on the dynamic model.Be equipped with running gate system on dynamic model and the cover half, running gate system is made up of running channel and cast gate, and described running channel comprises ring gate on the dynamic model and the ring gate on the cover half.
On the die joint of dynamic model and cover half, be respectively equipped with overflow launder.Described overflow launder is no less than one.
The described slide block of loosing core comprises 1 cylinder slide block, 2 cylinders slide block, 3 cylinders slide block, the 4 cylinders slide block of loosing core of loosing core of loosing core of loosing core.
The utility model is compared with existing flowmeter shell mould and had the following advantages: (1) significantly reduces the pore of part inside.After the design of die casting system changed ring gate into, molten metal entered mould inside along the direction parallel with die cavity and is shaped, and core is not had direct percussion, and the liquid levelling surely fills type, help gas and discharge, thereby the pore of part inside reduces thereupon.(2) loss of reduction mould.After running gate system changed ring gate into, liquid stream reduced greatly to the percussion of core, and it is steady to fill type, thereby has reduced mold repair, had both increased and had also improved surface quality of workpieces die life simultaneously.(3) qualification rate of raising product.Improve the X-ray photo of part of back die casting as can be seen from mould, part annular seal groove, 4 cylinder porosity qualification rates reach more than 99%.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is specifically described.
Fig. 3 and Fig. 4 are the floor map of the dynamic model and the cover half of the utility model mould.Mould is involutory by dynamic model and cover half and forms, and the dynamic model die joint is opened cavity and formed the dynamic model die cavity and be provided with moving-mould-core 8 in the chamber, and the cover half die joint leaves cavity and forms the cover half die cavity and be provided with cover half core 13 in the chamber.The slide block of loosing core is installed on the dynamic model, and the described slide block of loosing core comprises 1 cylinder slide block 4,2 cylinders slide block 5,3 cylinders slide block 6, the 4 cylinders slide block 7 of loosing core of loosing core of loosing core of loosing core.Be equipped with running gate system on dynamic model and the cover half, running gate system is made up of running channel and cast gate, and running channel comprises ring gate 2-3 on the dynamic model and the ring gate 2-12 on the cover half.
Fig. 1 and Fig. 2 are the floor map of the dynamic model and the cover half of flowmeter shell mould in the prior art, and as shown in the figure, running channel of the prior art is to adopt side running channel 1-11 is set on cover half.
Side running channel design on the cover half of available technology adopting, can obviously find out from Fig. 2, owing to water road shape, ingate 1-14 is directly to the core of 1,3,4 cylinders, when molten metal flows into die cavity when inner, liquid stream is also directly to 1,3,4 cylinder cores, form bigger impact, certainly will cause molten metal to scatter and splash, liquid stream is disorderly, gas is discharged difficulty, and the part internal porosity of die casting is more.And the ring gate that the utility model adopts design, changed the shape and the trend of running channel in the prior art, make when molten metal flows into die cavity inside, the liquid flow path direction enters mould inside along the direction parallel with die cavity, core there is not direct percussion, therefore the liquid levelling surely fills type, helps gas and discharges.
The utility model is respectively equipped with overflow launder 9 on the die joint of dynamic model and cover half, described overflow launder is no less than one.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art to some part wherein some changes that may make all embodied principle of the present utility model, belong within the protection domain of the present utility model.
