Abstract
The utility model relates to a sand ejecting device for a punch-out box, which comprises a punch head, a group of guide rods and a cylinder. The upper end face of the punch head is an acting face; the guide rods are arranged vertically and are respectively arranged in corresponding guide rod seats, and the upper ends of the guide rods are embedded in the punch head and are uniformly distributed relative to the lower end face of the overall punch head so that the movement of the punch head in the horizontal direction is limited, and the punch head can move freely in the vertical direction; and the head part of a piston rod of the cylinder leans against the lower end face of the punch head to form driving force to drive the punch head to move upwards. Since the original downward punching is changed into upward ejection, the utility model solves the problem in the downward punching that the speed for the cast product to go out of the box is too high under the common effect of the gravity and the impact force, thereby reducing the risk of damage to the cast product which is not completely cooled.
Description
Technical field
The utility model relates to a kind of being used for when disclosing case and ejects the sand device with what close-in the sandbox and foundry goods separated with sandbox.
Background technology
In the casting and molding transfer matic, before disclosing case, to cool off foundry goods, but some casting section thickness is thicker, though cooling processing through cooling section, but foundry goods can not obtain cooling fully, when the operation of case is disclosed in execution downwards, because it is very big to disclose case strength, impulsive force is very big, being the vibrations that rely on external force when disclosing case separates the close-in the sandbox and foundry goods and sandbox, disclosing of carrying out when the thicker foundry goods of wall thickness does not cool off fully is out of shape or the crack after the case operation will cause the foundry goods that cools off fully not to be subjected to impacting, thereby the situation that causes foundry goods to scrap takes place.Because the simple operation that relies on prolongation to improve cooling rate cool time is also uneconomical concerning actual production, thereby preferably discloses case by adjustment and achieve the goal.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned deficiency, provide a kind of can avoid damaging the thicker workpiece of wall thickness since scrap after disclosing case under the cooling situation not in place eject the sand device; Its technical problem to be solved can be implemented by the following technical programs.
A kind of be used to disclose case eject the sand device, comprising:
One discloses head, and a described upper surface of disclosing is an acting surface; With
One group of guide post of vertically arranging, described each guide post are located at respectively separately in the guide rod seat, and the upper end of described each guide post is embedded in described disclosing in the head and with respect to a whole lower surface of disclosing and is even dispersed arrangement; Form the guide post group to described control of disclosing head, and keep disclosing the move freely state of head in the mobile restricted and vertical position of level position in space bit; With
One oil cylinder, the head of described oil cylinder piston bar lean on described lower surface of disclosing head, form one and drive the described driving force that head makes progress of disclosing.
That adopts this technical scheme ejects the sand device, the excessive deficiency of bringing of solution impulsive force when disclosing case, by original disclosing being changed into upwards top downwards, so just solved the too fast problem of speed that acts on when disclosing because in gravity and the impulsive force when making the foundry goods outlet downwards.Thereby reduced not cooling off the damage probability of foundry goods fully.
As one of preferred embodiment of the technical program, described piston rod head with disclose the geometric center position that leaning of a lower surface a little is positioned at the lower surface.When appearing at centre bit, effect point helps the more optimization, more economical of active force.
As the further improvement of the technical program, described piston rod head can be fixedlyed connected with the described head of disclosing.
Also as one of preferred embodiment of the technical program, described guide post is 2 or 3.Adopt 2 or 3 guide post to realize required effect with few structure of trying one's best.
As the further improvement of the technical program, described upper surface of disclosing head is the plane.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model being done one describes in detail.
Fig. 1 is a structural representation of the present utility model;
---disclose 2---guide post 21---guide rod seat a 3---oil cylinder among the figure: 1
The specific embodiment
What be used to disclose case as shown in Figure 1 ejects the sand device, disclose 1 acting surface up, the following left and right sides is fixing by guide post 2 respectively, guide post 2 is set out from guide rod seat 21, disclose a middle part of 1 lower end and contact with the piston rod head of oil cylinder 3, piston rod head leans to be disclosed on the head, by the liquid presses piston pole promotion of oil cylinder, realize jack-up and the operation that falls to disclosing head, and then can be used to disclose the sand that ejects of case.
Two guide rod seats can connect as one by a plate (representing with double dot dash line among the figure), because guide post is by the spacing and guiding of guide rod seat institute, thereby disclose head and only limit in the up and down motion in orientation, the skew in its orientation, left and right sides will be restricted, and can help the application of force that it discloses case like this.And a smooth upper side of disclosing also helps sandbox finished and discloses the case operation.
This device solves when disclosing case downwards because it is very big to disclose case strength, impulsive force is very big, causes fully that the foundry goods of cooling is not subjected to impacting back distortion or crack, the problem that causes foundry goods to scrap has been brought into play positive effect.
Claims (5)
- One kind be used to disclose case eject the sand device, it is characterized in that, comprising:One discloses head, and a described upper surface of disclosing is an acting surface; WithOne group of guide post of vertically arranging, described each guide post are located at respectively separately in the guide rod seat, and the upper end of described each guide post is embedded in described disclosing in the head and with respect to a whole lower surface of disclosing and is even dispersed arrangement; Form the guide post group to described control of disclosing head, and keep disclosing the move freely state of head in the mobile restricted and vertical position of level position in space bit; WithOne oil cylinder, the head of described oil cylinder piston bar lean on described lower surface of disclosing head, form one and drive the described driving force that head makes progress of disclosing.
- According to claim 1 described be used to disclose case eject the sand device, it is characterized in that, described piston rod head with disclose the geometric center position that leaning of a lower surface a little is positioned at the lower surface.
