The embodiment of the application provides an ejection mechanism and a mold ejection system. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

Firstly, the embodiment of the application provides an ejection mechanism, which comprises an inclined top seat, a sliding block and an inclined ejector rod, wherein the sliding block is connected with the inclined top seat in a sliding and rotating manner, the sliding block has a sliding direction and a first rotation axis relative to the inclined top seat, and the first rotation axis extends along the sliding direction; the oblique ejector rod is rotatably connected with the sliding block and is provided with a second rotating axis relative to the sliding block, and the first rotating axis and the second rotating axis form an included angle.

Fig. 1 is a schematic structural diagram of an ejection mechanism according to an embodiment of the present application, and as shown in fig. 1, the ejection mechanism 100 includes an inclined top seat 110, the inclined top seat 110 is used for supporting the ejection mechanism 100 and positioning a position of the ejection mechanism 100, and the position of the inclined top seat 110 can be adjusted according to an actual design requirement to ensure that the ejection mechanism 100 can normally complete an ejection operation.

The ejection mechanism 100 further comprises a slider 120, the slider 120 is connected with the slanted ejecting base 110 in a sliding and rotating manner, the slider 120 has a sliding direction and a first rotation axis relative to the slanted ejecting base 110, and the first rotation axis extends along the sliding direction, so that the slider 120 can slide on the slanted ejecting base 110 during the ejection process of the ejection mechanism 100, and the normal operation of the ejection mechanism 100 is ensured; meanwhile, the slider 120 can also rotate around the inclined top seat 110 to perform angle compensation on the ejection mechanism 100, so that the movement interference of the ejection mechanism 100 caused by manufacturing accuracy or installation error is reduced, and the service life of the ejection mechanism 100 is prolonged.

The sliding direction of the sliding block 120 relative to the inclined top seat 110 can be adjusted according to actual design requirements, and only the requirement that the ejection mechanism 100 can move in the corresponding direction in the ejection process is met. Of course, the first rotation axis of the slider 120 can also be adjusted according to the setting mode of the ejection mechanism 100 in actual design requirements, and it is only necessary to ensure that the angle compensation requirement of the ejection mechanism 100 in the direction can be met when the slider 120 rotates around the first rotation axis.

The ejection mechanism 100 further comprises an oblique ejector rod 130, the oblique ejector rod 130 is rotatably connected with the sliding block 120, the oblique ejector rod 130 has a second rotation axis relative to the sliding block 120, the oblique ejector rod 130 is rotatably connected with the sliding block 120, so that the ejection mechanism 100 can rotate around the sliding block 120 in the ejection process if the oblique ejector rod 130 generates motion interference due to machining precision or installation errors, the generated angle error is compensated, and the situation that the oblique ejector rod 130 is clamped or broken due to mismatching of angles is avoided, so that the ejection mechanism 100 fails.

The second rotation axis of the lifter 130 can be adjusted according to design requirements, and only the lifter 130 needs to be ensured to meet the requirement of angle compensation of the ejection mechanism 100 in the direction when rotating around the slider 120. During actual manufacturing, the first rotation axis of the oblique ejector rod 130 and the second rotation axis of the slider 120 can be arranged at an included angle, so that the rotation direction of the oblique ejector rod 130 is different from that of the slider 120, thereby realizing angle compensation of the ejection mechanism 100 in different directions, improving the effect of angle compensation of the ejection mechanism 100, reducing the risk that the oblique ejector rod 130 is bent or even broken due to stress concentration in the ejection process, and prolonging the service life of the ejection mechanism 100.

Optionally, in the embodiment of the present application, a first guide hole 111 extending along the sliding direction is formed in the slanted ejecting seat 110, the slider 120 includes a first guide post 121, and the first guide post 121 is slidably inserted into the first guide hole 111, so that the first guide post 121 is rotatably connected to the slanted ejecting seat 110. The rotational connection between the first guiding column 121 and the slanted ejecting base 110 enables the ejection mechanism 100 to realize angle compensation through the rotation of the first guiding column 121 when an angle error occurs in a direction of rotation around the first rotation axis during the ejection process, thereby avoiding the occurrence of motion interference or stress concentration in the direction of the ejection mechanism 100 to cause a failure of the ejection mechanism 100.

The first guide hole 111 can penetrate through the slanted ejecting seat 110 along the sliding direction of the slider 120, and can also partially extend from one side of the slanted ejecting seat 110 to the other side along the sliding direction of the slider 120, and only the extending length of the first guide hole 111 needs to satisfy the sliding distance of the first guide column 121 in the ejection process of the ejection mechanism 100, and the first guide column 121 cannot slide out of the first guide hole 111 in the ejection process.

It should be noted that the outer surface of the first guiding column 121 is a convex curved surface, the inner wall of the first guiding hole 111 that is matched with the convex curved surface is also a curved surface, and through the hinge fit between the curved surface and the curved surface, the stress generated on the first guiding column 121 when the first guiding column 121 rotates around the slanted ejecting base 110 can be reduced, so that the first guiding column 121 is prevented from being broken due to stress concentration during the rotation process, and the service life of the ejection mechanism 100 is greatly prolonged.

Optionally, the surface of the inclined top seat 110 is provided with a first opening 112 extending along the sliding direction, the first opening 112 passes through the inner wall of the first guide hole 111 to communicate with the first guide hole 111, the slider 120 includes a first mounting portion 122 connected with the first guide column 121, and the first mounting portion 122 passes through the first opening 112 to be connected with the inclined top rod 130. Through the arrangement of the first opening 112, when the slider 120 slides in the first guide hole 111 on the inclined top base 110, the first mounting part 122 can be located above the inclined top base 110, rather than being limited to the side of the inclined top base 110, so that the length of the first guide column 121 in the sliding direction can be the same as that of the mounting part, and the first guide column 121 does not need to be extended along the sliding direction to rotate in the first guide hole 111, thereby reducing the size of the first guide column 121 and saving the manufacturing cost.

The first opening 112 can penetrate through the surface of the slanted ejecting base 110 along the sliding direction of the slider 120, and can also partially extend from one side of the slanted ejecting base 110 to the other side along the sliding direction of the slider 120, and the extending length of the first opening 112 only needs to be long enough to satisfy the moving distance of the first mounting portion 122 when the first guiding column 121 slides in the first guiding hole 111. That is, the first mounting portion 122 will not collide with the sidewall of the first opening 112 during the ejection process, so as to avoid affecting the normal operation of the ejection process.

Alternatively, the first opening 112 can be formed in the middle area of the surface of the slanted ejecting seat 110, i.e. both sides of the opening do not penetrate through the surface of the slanted ejecting seat 110. At this time, the first guide post 121 of the slider 120 cannot be directly inserted into the first guide hole 111 from the side of the slanted ejecting seat 110 in a sliding manner, and the slanted ejecting seat 110 needs to be designed to be composed of two parts. During installation, the slanted ejecting seat 110 is detached first, the first guide column 121 of the slider 120 is placed between the two parts of the slanted ejecting seat 110, and then the two parts of the slanted ejecting seat 110 are combined, so that the slider 120 is connected with the slanted ejecting seat 110 in a sliding manner and in a rotating manner.

It should be noted that the extension length of the first opening 112 along the sliding direction of the slider 120 needs to be enough that when the first guiding column 121 slides in the first guiding hole 111, the first mounting portion 122 has a sufficient moving distance, that is, the first mounting portion 122 cannot collide with two side walls of the first opening 112 during the ejection process, so as to avoid affecting the normal operation of the ejection process.

Optionally, the first opening 112 has two opposite first inner walls 1121, the two first inner walls 1121 are sequentially distributed along the second rotation axis, and the first inner walls 1121 gradually expand in a direction away from the first guide hole 111. The arrangement of the first inner wall 1121 enables the first guide post 121 to rotate in the first guide hole 111, so as to limit the rotation position of the first mounting portion 122, and meanwhile, when the first mounting portion 122 rotates to contact with the first inner wall 1121, the force-bearing area of the first mounting portion 122 is a side surface contacting with the first inner wall 1121, rather than a force-bearing point or a line, so that the force-bearing of the first mounting portion 122 is more uniform, and the damage of the slider 120 due to stress concentration is avoided, thereby affecting the normal use of the ejection mechanism 100.

In order to ensure that the first guide post 121 can rotate normally in the first guide hole 111, the first inner wall 1121 is spaced apart from the side surface of the first mounting portion 122 so that the first mounting portion 122 can rotate around the first rotation axis within the spacing range. The size of this interval can be according to actual design demand, if machining precision scope or erection angle error range etc. carry out corresponding regulation, only need guarantee ejection mechanism 100 can satisfy the angle compensation demand in this interval scope.

It should be noted that the first inner wall 1121 can be uniformly expanded along the direction away from the first guide hole 111, that is, the first inner wall 1121 is disposed along the direction away from the first guide hole 111 and is an inclined plane, an included angle between two opposite first inner walls 1121 is greater than an included angle between two opposite side surfaces of the first mounting portion 122 and the first inner wall 1121, that is, a gap is left between the first inner wall 1121 and the side surface of the first mounting portion 122, so as to ensure that the slider 120 normally rotates relative to the lifter base 110.

In some embodiments, the first mounting portion 122 has a first mounting surface 1221 engaged with the first inner wall 1121, the first mounting surface 1221 can be disposed in an inclined manner, the inclined direction of the first mounting surface is the same as the inclined direction of the first inner wall 1121, but the inclined angles are different, and the design of such a structure is beneficial to the engagement of the first mounting portion 122 with the first inner wall 1121 in the rotation process, so that when the first mounting portion 122 rotates to contact with the first inner wall 1121, the contact area of the first mounting portion 122 is larger, that is, the stressed area of the first mounting portion 122 is larger, which is beneficial to relieving the stress concentration on the first mounting portion 122, thereby reducing the risk of damage of the first mounting portion 122 due to excessive stress, and improving the service life of the whole ejection mechanism 100.

In other embodiments, the first inner wall 1121 is non-uniformly expanded along a direction away from the first guiding hole 111, that is, the first inner wall 1121 can be configured as a convex curved surface structure, and the first inner wall 1121 and the inner wall of the first guiding hole 111 are in transition connection by using a smooth curved surface. Similarly, the first mounting surface 1221 of the first mounting portion 122, which is close to one end of the first guiding post 121 and is engaged with the first inner wall 1121, is configured as a concave curved surface, and when the first mounting portion 122 rotates to contact with the first inner wall 1121, the contact surface is a curved surface structure, which further increases the contact area; meanwhile, the curved surface structure can further alleviate stress concentration on the contact surface relative to the inclined surface, thereby further reducing the risk of damage of the first mounting portion 122 due to excessive stress and improving the service life of the whole ejection mechanism 100.

Optionally, in the embodiment of the present application, a second guide hole 123 is formed in the slider 120, the slanted ejecting rod 130 includes a second guide post 131, and the second guide post 131 is slidably inserted into the second guide hole 123, so that the second guide post 131 is rotatably connected to the slider 120. The rotational connection between the second guiding post 131 and the slider 120 enables the ejection mechanism 100 to realize angle compensation through the rotation of the second guiding post 131 when an angle error occurs in a direction of rotation around the second rotation axis during the ejection process, thereby avoiding the occurrence of motion interference or stress concentration in the direction of the ejection mechanism 100 to cause a failure of the ejection mechanism 100.

The extending direction of the second guiding hole 123 and the extending direction of the first guiding hole 111 form an included angle, so that the second rotation axis of the oblique ejector rod 130 relative to the slider 120 and the first rotation axis of the slider 120 relative to the oblique ejector seat 110 form an included angle, so that the ejection mechanism 100 can perform angle compensation in two directions, the angle compensation effect of the ejection mechanism 100 is further improved, and the smooth operation of the ejection mechanism 100 is ensured.

Optionally, the second guide hole 123 may penetrate through the slider 120, or may partially extend from one side of the slider 120 to the other side, and it is only necessary that the extension length of the second guide hole 123 is enough to ensure that the second guide post 131 does not slide out of the second guide hole 123 in the ejection process of the ejection mechanism 100.

It should be noted that the outer surface of the second guiding column 131 is a convex curved surface, the inner wall of the second guiding hole 123 matched with the convex curved surface is also a curved surface, and through the hinge fit between the curved surface and the curved surface, the stress generated on the second guiding column 131 when the second guiding column 131 rotates around the slider 120 can be reduced, so that the second guiding column 131 is prevented from being broken due to stress concentration during the rotation process, and the service life of the ejection mechanism 100 is greatly prolonged.

Optionally, the surface of the slider 120 is provided with a second opening 124, an extending direction of the second opening 124 is consistent with an extending direction of the second guide hole 123, the second opening 124 passes through an inner wall of the second guide hole 123 to communicate with the second guide hole 123, the lifter 130 includes a second mounting portion 132, and the second mounting portion 132 passes through the second opening 124 to be connected with the second guide post 131. Through the arrangement of the second opening 124, when the inclined push rod 130 rotates in the second guide hole 123 on the slider 120, the second mounting part 132 can be located above the slider 120, rather than being limited to the side of the slider 120, so that the length of the second guide post 131 in the extending direction of the second guide hole 123 can be the same as that of the mounting part, and the second guide post 131 does not need to be extended along the extending direction of the second guide hole 123 to rotate in the second guide hole 123, thereby reducing the size of the second guide post 131 and saving the manufacturing cost.

The second opening 124 penetrates the surface of the slider 120 along the extending direction of the second guiding hole 123, or partially extends from one side of the slider 120 to the other side along the extending direction of the second guiding hole 123, and it is only necessary that the extending length of the second opening 124 can satisfy the rotating area of the second mounting portion 132 when the second guiding column 131 rotates in the second guiding hole 123. That is, the second mounting portion 132 will not collide with the sidewall of the second opening 124 during the ejection process, so as to avoid affecting the normal operation of the ejection process.

Alternatively, the second opening 124 can also be formed in the middle area of the surface of the slider 120, i.e. neither side of the opening extends through the surface of the slider 120. At this time, the second guiding post 131 of the slanted ejecting seat 110 cannot be directly inserted into the second guiding hole 123 by sliding from the side of the slider 120, and the slider 120 needs to be designed to be composed of two parts. During installation, the sliding block 120 is detached, the second guide column 131 of the oblique ejector rod 130 is placed between the two parts of the sliding block 120, and then the two parts of the sliding block 120 are combined, so that the oblique ejector rod 130 is rotatably connected with the sliding block 120.

It should be noted that the extension length of the second opening 124 along the extension direction of the second guiding hole 123 needs to be enough that when the second guiding column 131 rotates in the second guiding hole 123, the second mounting portion 132 has a sufficient rotating distance, that is, the second mounting portion 132 cannot collide with two side walls of the second opening 124 during the ejection process, so as to avoid affecting the normal operation of the ejection process.

Alternatively, the second opening 124 has two opposite second inner walls 1241, the two second inner walls 1241 are distributed along the first rotation axis in sequence, and the second inner walls 1241 gradually expand in a direction away from the second guide hole 123. The arrangement of the second inner wall 1241 enables the second guide column 131 to rotate in the second guide hole 123, the rotation position of the second mounting portion 132 is limited, meanwhile, when the second mounting portion 132 rotates to contact with the second inner wall 1241, the stressed area of the second mounting portion 132 is a side surface contacting with the second inner wall 1241 instead of a stressed point or a line contact, so that the stress of the second mounting portion 132 is more uniform, the oblique mandril 130 is prevented from being damaged due to stress concentration, and the normal use of the ejection mechanism 100 is affected.

In order to ensure that the second guide post 131 can rotate normally in the second guide hole 123, the second inner wall 1241 is spaced apart from the side of the second mounting portion 132, so that the second mounting portion 132 can rotate around the second rotation axis within the gap. The size of this interval can be according to actual design demand, if machining precision scope or erection angle error range etc. carry out corresponding regulation, only need guarantee ejection mechanism 100 can satisfy the angle compensation demand in this interval scope.

It should be noted that the second inner wall 1241 can be uniformly expanded along the direction away from the second guide hole 123, that is, the second inner wall 1241 is disposed as an inclined plane along the direction away from the second guide hole 123, an included angle between two opposite second inner walls 1241 is greater than an included angle between two opposite side surfaces of the second mounting portion 132 and the second inner wall 1241, that is, a gap is left between the second inner wall 1241 and the side surface of the second mounting portion 132, so as to ensure the normal rotation of the lifter rod 130 relative to the slider 120.

In some embodiments, the second mounting portion 132 has a second mounting surface 1321 engaged with the second inner wall 1241, the second mounting surface 1321 can be disposed in an inclined manner, an inclined direction of the second mounting portion is the same as an inclined direction of the second inner wall 1241, but an inclined angle of the second mounting portion is different, the design of the structure is favorable for the engagement of the second mounting portion 132 with the second inner wall 1241 in a rotating process, when the second mounting portion 132 rotates to be in contact with the second inner wall 1241, a contact area of the second mounting portion is larger, that is, a stress area of the second mounting portion 132 is larger, and the stress concentration on the second mounting portion 132 is favorably relieved, so that a risk that the second mounting portion 132 is damaged due to overlarge stress is reduced, and the service life of the whole ejection mechanism 100 is prolonged.

In other embodiments, the second inner wall 1241 is non-uniformly expanded along the direction away from the second guiding hole 123, that is, the second inner wall 1241 is configured as a convex curved structure, and the second inner wall 1241 and the inner wall of the second guiding hole 123 are in transition connection by using a smooth curved surface. Similarly, the second mounting surface 1321 of the second mounting portion 132, which is close to one end of the second guiding post 131 and is matched with the second inner wall 1241, can be set to be a concave curved surface, and when the second mounting portion 132 rotates to be in contact with the second inner wall 1241, the contact surface is a curved surface structure, which further increases the contact area; meanwhile, the curved surface structure can further alleviate stress concentration on the contact surface relative to the inclined surface, thereby further reducing the risk of damage of the second mounting portion 132 due to excessive stress and improving the service life of the whole ejection mechanism 100.

Optionally, in the embodiment of the present application, the second guiding column 131 on the oblique top rod 130 is set to be spherical, and correspondingly, the second guiding hole 123 on the sliding block 120 is set to be a spherical hole matched with the second guiding column 131, and the design of the spherical structure enables the oblique top rod 130 to rotate in each direction in the circumferential direction relative to the sliding block 120, so as to implement angle compensation in more directions, and further avoid the oblique top rod 130 from being jammed or broken due to motion interference in the ejection process.

The second opening 124 on the surface of the slider 120 can also be designed as a circular opening communicated with the second guide hole 123, and gaps are left between the periphery of the second opening 124 and the side surface of the second mounting portion 132, so as to ensure that the angle compensation can be performed on the inclined push rod 130 within the gap range in the push-out process.

It should be noted that, when the second guiding column 131 is designed to be a spherical structure, in order to implement the installation between the lifter 130 and the slider 120, the slider 120 needs to be designed to be a detachable structure, and screws or other fixing methods can be used between the detachable parts. During installation, the sliding block 120 is detached, the second guide column 131 is placed in the second guide hole 123, and then the sliding block 120 is combined, so that the oblique ejector rod 130 is rotatably connected with the sliding block 120.
