Description
Technical field
The utility model relates to the technical field of processing equipment of water jacket, and specifically a kind of engine cooling water jacket makes of the core box with catch.
Background technology
Water jacket (Water Jackets) refers to the space between the inside and outside shell of cylinder block and cylinder cover, and namely cooling fluid circulates betwixt, is cylinder body and cylinder cap cooling.
Water jacket cavity gathers, complex structure, a lot of partial cross section amasss little, difficulty of processing is large, sand core structure corresponding is with it complicated, be difficult to shaping, and require high to the bond performance of core, in order to improve the intensity of core, when preventing that core Forming Quality is not high causes casting, aluminium water breaks through core, utilization penetrate sand machine carry out penetrating sand time, need there are being enough impulsive forces, core is shaping within moment, ensure, between core, there is stronger bond strength, but penetrating sand machine with upper core box docking operation, core sand is often had independently to flow in core box, core box porch is caused to block, the fast rapid fire sand of sand machine is penetrated in impact, thus easily reduce the bond strength of core.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of engine cooling water jacket to make of the core box with catch.
The utility model solves its technical problem and realizes by the following technical solutions:
A kind of engine cooling water jacket makes with the core box with catch, comprise core box, four angles place of described upper core box lower surface is equipped with guide pillar, and upper core box is evenly distributed with blasting unit, during use, core sand is entered in upper core box by blasting unit Fast Filling by external sand machine of penetrating.The upper surface of described blasting unit is all lower than the upper surface of upper core box, the lower end of blasting unit is equipped with rubber sleeve, the upper surface of described blasting unit is all posted the diameter catch identical with the diameter of blasting unit upper surface, described catch is evenly provided with four spaced bar holes of 45 °, the upper surface of catch is concordant with the upper surface of upper core box.
During use, external sand machine of penetrating is pressed on corresponding catch, the core sand penetrated in sand machine can not fall from catch, prevent from penetrating before sand machine do not carry out blowing and penetrate, core sand falls in core box, when penetrating after sand machine starts, because catch is provided with bar hole, catch between described bar hole is bent, and catch bends by huge air pressure, makes core sand be full of core box instantaneously.
Described catch adopts spring steel to make, to ensure that catch has stronger elasticity, thus after making external sand machine of penetrating impact catch, catch can reset rapidly, the thickness of catch is 0.25mm, the thickness of catch is summed up and is drawn in test of many times, ensures that catch has compared with while strong elasticity, is not easy bending.
The width of described bar hole is 1-2.5mm, the width of bar hole is excessive easily cause core sand under leak, reduce bar hole and stop the function of core sand, bar hole width is too small easily causes the divided part opened on catch to be difficult to bending, reduces the elasticity of catch.
Described catch is coated with adhesive tape, described adhesive tape is provided with the circular hole corresponding with catch, the diameter of described circular hole is identical with the length of bar hole, during use, described adhesive tape covers on catch, circular hole on adhesive tape just in time reserves exposed space for the bar hole on catch, makes core sand process, changes conveniently after adhesive tape wearing and tearing.
The beneficial effects of the utility model are: the utility model easily blocks the situation of blasting unit for core sand in prior art, adopt and there is flexible catch as the method for leaking under preventing core sand with M shape bar hole, prevent the upper core box below core sand blocking blasting unit and blasting unit, for penetrating sand machine, core sand fast ram is entered upper core box removing obstacles, to improve the bond strength of core and bonding density, improve and fill type power, the sand hole of reduction type in-core, and reducing source of the gas loss, described catch resets rapidly penetrating after sand penetrated by sand machine; Catch volume is little, and structure is simple, and bonding installation is convenient, changes difficulty little, with low cost, very practical, Be very effective.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figures 1 to 5, a kind of engine cooling water jacket makes with the core box with catch, comprise core box 1, four angles place of described upper core box 1 lower surface is equipped with guide pillar 2, upper core box 1 is evenly distributed with blasting unit 3, the upper surface of described blasting unit 3 is all lower than the upper surface of upper core box 1, the lower end of blasting unit 3 is equipped with rubber sleeve 4, the upper surface of described blasting unit 3 is all posted the catch 5 that diameter is identical with the diameter of blasting unit 3 upper surface, described catch 5 is evenly provided with four spaced bar holes of 45 ° 6, the upper surface of catch 5 is concordant with the upper surface of upper core box 1.
Described catch 5 adopts spring steel to make, and the thickness of catch 5 is 0.25mm, and the width of described bar hole 6 is 1 to 2.5mm, and concrete width is depending on the granularity of core sand.Described catch 5 is coated with adhesive tape 7, described adhesive tape 7 is provided with the circular hole 8 corresponding with catch 5, and the diameter of described circular hole 8 is identical with the length of bar hole 6, and described adhesive tape 7 covers on catch 5, circular hole 8 on adhesive tape 7 just in time reserves exposed space for the bar hole 6 on catch 5, and core sand is passed through.
During use, first external sand machine of penetrating is pressed on corresponding catch 5, the core sand penetrated in sand machine can not fall from catch 5, prevent from penetrating before sand machine do not carry out blowing and penetrate, core sand falls in core box 1, start afterwards and penetrate sand machine, because catch 5 is provided with bar hole 6, the catch 5 separated between described bar hole 6 can independently bend, penetrate the huge air pressure produced when sand penetrated by sand machine catch 5 is bent, core sand is made to be full of core box 1 instantaneously, because core sand is pressed into instantaneously not entering before under the state in blasting unit 3, core sand is all mutually extrude under unencumbered high-speed moving state, adhesion is strong, shaping whole, be not easy loose.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
