Description
Technical field
The present invention relates to the technical field of processing equipment of water jacket, specifically a kind of engine cooling water jacket system
Act on 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 coolant i.e. exists
Circulate therebetween, lower the temperature for cylinder body and cylinder cap.
Water jacket cavity gathers, and structure is complicated, and a lot of partial cross sections amass little, and difficulty of processing is big, corresponding
Sand core structure is complicated, it is difficult to molding, and the bond performance of core is required height, in order to improve the intensity of core,
Prevent core Forming Quality the highest cause casting time aluminum water break through core, utilization penetrate sand machine carry out penetrating sand time,
Need there are being enough impulsive forces, by core molding within moment, it is ensured that have stronger combination between core
Intensity, but in penetrating sand machine and upper core box docking operation, often have core sand independently to flow in core box, make
Core box porch blocking on one-tenth, impact is penetrated the fast rapid fire sand of sand machine, thus is easily reduced the bond strength of core.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of engine cooling water jacket to make of with catch
Core box.
The present invention solves its technical problem and realizes by the following technical solutions:
A kind of engine cooling water jacket makes of the core box with catch, including upper core box, under described upper core box
Being equipped with guide pillar at four angles of end face, upper core box is evenly distributed with blasting unit, during use, external penetrates
Core sand is entered in upper core box by sand machine by blasting unit Fast Filling.The upper surface of described blasting unit is below core
The upper surface of box, the lower end of blasting unit is equipped with rubber sleeve, and the upper surface of described blasting unit is all posted diameter
The catch identical with the diameter of blasting unit upper surface, described catch is uniformly provided with four spaced 45 °
Bar hole, 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 the catch of correspondence, and penetrating the core sand in sand machine can not be from catch
Falling, prevent from penetrating before sand machine do not carries out blowing and penetrate, core sand falls in core box, when penetrating after sand machine starts,
Owing to catch is provided with bar hole, the described catch between bar hole is bent, in order to huge air pressure will
Catch bends, and makes core sand moment be full of core box.
Described catch uses spring steel to make, to ensure that catch has stronger elasticity, so that external
Penetrate sand machine impact catch after, catch can reset rapidly, and the thickness of catch is 0.25mm, the thickness of catch be
In test of many times, summary draws, it is ensured that while catch has relatively strong elasticity, it is not easy to bending.
The width of described bar hole is 1-2.5mm, and the width of bar hole is excessive is easily caused under core sand leakage, reduces
Bar hole stops the function of core sand, and the too small part being partitioned from catch that is easily caused of bar hole width is difficult to
Bending, reduces the elasticity of catch.
Being coated with adhesive tape on described catch, described adhesive tape is provided with the circular hole corresponding with catch, described circular hole
Diameter is identical with the length of bar hole, and during use, described adhesive tape covers on catch, and the circular hole on adhesive tape is just
Reserving exposed space for the bar hole on catch well, make core sand process, it is convenient to change after adhesive tape abrasion.
The invention has the beneficial effects as follows: the present invention is directed to core sand in prior art and easily block the situation of blasting unit,
Use the resilient catch of tool with M shape bar hole as preventing the method for leakage under core sand, prevent core sand
Upper core box below blocking blasting unit and blasting unit, enters upper core box removing barrier for penetrating sand machine by core sand fast ram
Hinder, 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, simple in construction,
Bonding installation is convenient, changes difficulty little, and with low cost, very useful, effect is notable.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with being specifically illustrating, the present invention is expanded on further.
As shown in Figures 1 to 5, a kind of engine cooling water jacket makes of the core box with catch, including upper core
Box 1, is equipped with guide pillar 2 at four angles of described upper core box 1 lower surface, upper core box 1 is evenly distributed with and penetrates sand
Cylinder 3, the upper surface of described blasting unit 3 is below the upper surface of core box 1, and the lower end of blasting unit 3 is equipped with rubber
Gum cover 4, the upper surface of described blasting unit 3 is all posted the catch that diameter is identical with the diameter of blasting unit 3 upper surface
5, described catch 5 is uniformly provided with four spaced bar holes of 45 ° 6, the upper surface of catch 5 and upper core
The upper surface of box 1 is concordant.
Described catch 5 uses 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, concrete width is depending on the granularity of core sand.Adhesive tape 7, described glue it is coated with on described catch 5
Being provided with the circular hole 8 corresponding with catch 5 with 7, the diameter of described circular hole 8 is identical with the length of bar hole 6, described
Adhesive tape 7 covers on catch 5, and the circular hole 8 on adhesive tape 7 just reserves exposed space for the bar hole 6 on catch 5,
Core sand is made to pass through.
During use, being first pressed in by external sand machine of penetrating on the catch 5 of correspondence, penetrating the core sand in sand machine can not be from
Falling on catch 5, prevent from penetrating before sand machine do not carries out blowing and penetrate, core sand falls in core box 1, starts afterwards
Penetrating sand machine, owing to catch 5 is provided with bar hole 6, the catch 5 separated between described bar hole 6 can be independent
Bending, penetrates the huge air pressure produced when sand penetrated by sand machine and is bent by catch 5, makes core sand moment be full of upper core box 1,
Owing to core sand is to be pressed into by moment when not entering into before in blasting unit 3, core sand is all not have
Mutually extruding under the high-speed moving state hindered, adhesion is strong, and molding is whole, it is not easy to loose.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The industry
Skilled person will appreciate that, the present invention is not restricted to the described embodiments, in above-described embodiment and description
The principle that the present invention is simply described described, without departing from the spirit and scope of the present invention, the present invention
Also having various changes and modifications, these changes and improvements both fall within scope of the claimed invention.This
The claimed scope of invention is defined by appending claims and equivalent thereof.
