Description
Technical Field
The utility model relates to the technical field of molds, specifically speaking relates to a push up mechanism to one side.
Background
The angle ejection mechanism is a mechanism used for forming barbs in the product in the mold design. As shown in figure 1, the inclined top mechanism comprises an inclined top base 10 and an inclined top buckle 20, wherein the top of the inclined top base is provided with an I-shaped groove 11, the bottom of the inclined top buckle is provided with a barb 21 matched with the I-shaped groove 11, and the barb 21 can slide in the I-shaped groove 11.
At present, the I-shaped groove 11 of the inclined ejecting seat 10 is matched with the barb 21 of the inclined ejecting buckle 20 through a right angle, when the inclined ejecting mechanism resets, a mutual pulling force is generated between the inclined ejecting seat 10 and the inclined ejecting buckle 20, and the barb 21 at the weak position of the root part of the inclined ejecting is very easy to break due to the sharp angle.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a push up mechanism to one side, the cooperation is smooth and easy, long service life.
The utility model discloses a technical scheme that mechanism adopted is pushed up to one side is:
the utility model provides a push up mechanism to one side, includes to one side footstock and pushes up to one side and detains, first recess has been seted up at the footstock top to one side, the both sides of first groove opening part are equipped with first boss, the both sides of detaining the bottom to one side are seted up the second recess to make to one side to push up and detain the bottom and form the second boss, second boss and first recess clearance fit, first boss and second recess clearance fit, the contact surface of first boss and second recess is the arc surface.
Preferably, the second boss is matched with the side edge of the bottom of the first groove through a circular arc surface.
Preferably, the arc surface between the first boss and the first groove is a semicircular arc.
Preferably, the clearance between the first boss and the second groove is 0.04 mm.
Preferably, the fit clearance between the second boss and the first groove is 0.04 mm.
Preferably, the first boss and the second boss have the same height.
The utility model discloses a push up mechanism to one side's beneficial effect is: the first groove of the oblique top seat and the second boss of the oblique top buckle are in clearance fit to realize clamping. The first boss of oblique footstock and the second recess of oblique top knot pass through clearance fit, realize the screens once more. The oblique top buckle can slide on the oblique top seat in the horizontal direction, and the guide effect during resetting is realized. And the contact surface through first boss and second recess is the arc surface, effectively avoids the screens between first boss and the second recess, has guaranteed to push up to detain and pushes up the seat between the slope smoothly nature of complex to promote life to one side.

fig. 2 is a schematic structural diagram of the lifter mechanism of the present invention.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 2, an angle ejector mechanism includes an angle ejector base 30 and an angle ejector buckle 40. The top of the inclined top seat 30 is provided with a first groove 31, and two sides of the opening of the first groove 31 are provided with first bosses 32. The two sides of the bottom of the oblique top buckle 40 are provided with second grooves 41, and a second boss 42 is formed at the bottom of the oblique top buckle 40. The second boss 42 is clearance-fitted with the first groove 31, and the first boss 32 is clearance-fitted with the second groove 41. The inclined top buckle 40 can slide on the inclined top seat 30, and the inclined top buckle 40 can be guided by the inclined top seat 30 in the resetting process. The contact surface of the first boss 32 and the second groove 41 is an arc surface, and the bottom side edge of the second boss 42 and the first groove 31 is matched through the arc surface. The arc surface between the first boss 32 and the first groove 31 is a semi-arc. The first boss 32, the second groove 41, the second boss 42 and the first groove 31 are not easy to generate clamping position and stress concentration in the sliding fit process due to the arc surfaces of the matching surfaces, so that the inclined top seat 30 is prevented from being damaged due to the clamping position in the reset process. The heights of the first boss 32 and the second boss 42 are equal, so that the integral structure is effectively prevented from being firmer due to uneven stress.
The clearance between the first boss 32 and the second groove 41 is 0.04mm, and the fit clearance between the second boss 42 and the first groove 31 is 0.04 mm. Through close clearance fit, the sliding between the inclined top seat 30 and the inclined top buckle 40 is smoother, and the small clearance can avoid the clamping.
In the above scheme, the first groove 31 of the inclined top seat 30 and the second boss 42 of the inclined top buckle 40 are in clearance fit to realize clamping. The first boss 32 of the inclined top seat 30 and the second groove 41 of the inclined top buckle 40 are in clearance fit to realize clamping again. The inclined top buckle 40 can slide on the inclined top seat 30 in the horizontal direction, and the guiding function during resetting is realized. And the contact surface of the first boss 32 and the second groove 41 is an arc surface, so that the clamping position between the first boss 32 and the second groove 41 is effectively avoided, the smoothness of the matching between the inclined top buckle 40 and the inclined top seat 30 is ensured, and the service life is prolonged.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
