Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inclined top seats, and more specifically to a spherical movable seat of an inclined top seat of a mold. Background Art
[0002] The mold tilting top is a mechanism used in mold design to form the internal hook of the product. It is suitable for relatively simple hook situations. The mold tilting top can make the product inside the mold more smoothly when demolding and reduce the friction between the mold and the product. There is generally a tilting top seat at the root of the mold tilting top, which plays the role of limiting and fixing. However, the existing tilting top seat is prone to greater wear after long-term friction, and the heat generated after friction is large, resulting in a decrease in life. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a spherical movable seat for a mold inclined top seat, which has the advantages of reducing friction and increasing overall service life.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spherical movable seat of a mold inclined top seat, comprising: a base, a first mounting groove and a second mounting groove are provided inside the base, a telescopic rod is fixedly installed inside the second mounting groove, a spring is sleeved on the outside of the telescopic rod, a limiting sleeve is fixedly installed on the side of the spring close to the first mounting groove, and the limiting sleeve is arc-shaped; a sphere, a graphite column is fixedly installed on the outside of the sphere, a chamfered plane is provided on the top of the sphere, a through hole is provided inside the sphere, and the sphere is located inside the first mounting groove and has rotational freedom.
[0005] The beneficial effect of adopting the above technical solution is that the base supports the sphere, so that when the sphere rotates inside the first mounting groove, it supports the upper connecting part, thereby achieving the effect of inclined top support. At the same time, since the sphere has a certain degree of rotational freedom in the first mounting groove, it can drive the inclined rod to adjust the angle at any time, thereby achieving the effect of convenient adjustment.
[0006] As a preferred technical solution of the utility model, a limiting pad is fixedly installed inside the first installation groove, the limiting pad is semi-arc-shaped, there are two limiting pads, and the two limiting pads are located on the left and right sides of the sphere.
[0007] The beneficial effect of adopting the above technical solution is that when the sphere is installed into the first installation groove, the outer side of the sphere and the graphite column will contact the inner side of the limiting pad, so that the limiting pad increases the contact strength with the graphite column and prevents the sphere from rocking back and forth inside the first installation groove.
[0008] As a preferred technical solution of the utility model, a screw hole is opened inside the base, and there are two screw holes, which are respectively located on the left and right sides of the first installation groove.
[0009] The beneficial effect of adopting the above technical solution is that the screw hole passes through the interior of the base, and its main function is to engage with the bolt through the interior, so that the base is fixed, so that the base not only has a load-bearing effect, but also maintains the overall stability of the device.
[0010] As a preferred technical solution of the utility model, a ventilation hole and a heat dissipation groove are opened at the bottom end of the base, and a thermal conductive copper column is fixedly installed inside the heat dissipation groove. There are multiple heat dissipation grooves and multiple thermal conductive copper columns, and the multiple heat dissipation grooves and multiple thermal conductive copper columns are all located on the outside of the ventilation hole.
[0011] The beneficial effect of adopting the above technical solution is that the ventilation hole is located directly below the sphere. When the sphere and the graphite column rotate and rub inside the first mounting groove, a large amount of heat will be generated. At this time, the second mounting groove allows the air inside the base to circulate, thereby reducing the temperature inside the base, thereby increasing the service life of the device.
[0012] As a preferred technical solution of the utility model, the plurality of thermally conductive copper pillars are made of copper material, and the downward height values of the plurality of thermally conductive copper pillars are lower than the height values of the plurality of heat dissipation slots.
[0013] The beneficial effect of adopting the above technical solution is: the main function of the multiple heat-conducting copper columns is that due to the good thermal conductivity of copper, the heat inside the base is discharged to the outside, so that the heat between the graphite column and the base is reduced, thereby increasing the life of the graphite column and the base.
[0014] As a preferred technical solution of the utility model, there are two second installation grooves, both of which are located inside the base, and there are two springs, which are respectively located on the left and right sides of the sphere.
[0015] The beneficial effect of adopting the above technical solution is that the two springs will always provide elastic force to push the telescopic rod toward the central axis direction of the first installation groove. When the sphere needs to be installed, the sphere is squeezed toward the bottom of the first installation groove. At this time, the telescopic rod will shrink inward, thereby achieving the effect of facilitating installation.
[0016] As a preferred technical solution of the utility model, there are two limit sleeves, which are respectively located on the left and right sides of the sphere, and the extension lines on both sides of the two limit sleeves can surround a hollow circle.
[0017] The beneficial effect of adopting the above technical solution is: the main function of the two limit sleeves is that when the sphere is installed inside the first installation groove, the extension lines on both sides of the two limit sleeves can be surrounded by a hollow circle, but the diameter value will be smaller than the maximum diameter value of the sphere. Therefore, when rotating, the sphere will be limited up and down, thereby achieving convenient installation while maintaining the stability of the sphere.
[0018] As a preferred technical solution of the utility model, there are multiple graphite columns, and the multiple graphite columns are all located inside the first installation groove, and the multiple graphite columns are respectively in contact with the inside of the base.
[0019] The beneficial effect of adopting the above technical solution is that multiple graphite columns will be driven by the sphere to rotate. When the sphere rotates, some of the multiple graphite columns will contact the inner wall of the base, while the surface of the graphite columns is relatively smooth, and the contact area is a sphere protruding outward, so the contact area is small. Therefore, when the graphite column and the base rub against each other, the friction force generated is small, so the wear generated is small, thereby improving the overall life of the sphere.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figures 1 to 5 As shown, the utility model provides a spherical movable seat for a mold inclined top seat, comprising: a base 1, a first mounting groove 2 and a second mounting groove 3 are provided inside the base 1, a telescopic rod 4 is fixedly installed inside the second mounting groove 3, a spring 5 is sleeved on the outer side of the telescopic rod 4, a limiting sleeve 6 is fixedly installed on the side of the spring 5 close to the first mounting groove 2, and the limiting sleeve 6 is arc-shaped; a sphere 7, a graphite column 8 is fixedly installed on the outer side of the sphere 7, a chamfered plane 9 is provided on the top of the sphere 7, a through hole 10 is provided inside the sphere 7, and the sphere 7 is located inside the first mounting groove 2 and has rotational freedom.
[0028] The beneficial effect of adopting the above technical solution is that the base 1 supports the sphere 7, so that when the sphere 7 rotates inside the first mounting groove 2, it supports the upper connecting part to achieve the effect of inclined top support. At the same time, since the sphere 7 has a certain degree of rotational freedom in the first mounting groove 2, it can drive the inclined rod to adjust the angle at any time, thereby achieving the effect of convenient adjustment.
[0029] A limiting pad 11 is fixedly installed inside the first installation groove 2 . The limiting pad 11 is semi-arc-shaped. There are two limiting pads 11 , and both of them are located on the left and right sides of the sphere 7 .
[0030] The beneficial effect of adopting the above technical solution is: when the sphere 7 is installed into the inside of the first mounting groove 2, the outer side of the sphere 7 and the graphite column 8 will contact the inner side of the limiting pad 11, so that the limiting pad 11 increases the contact force with the graphite column 8, preventing the sphere 7 from rocking back and forth inside the first mounting groove 2.
[0031] The base 1 is provided with two screw holes 12 , which are respectively located at the left and right sides of the first installation slot 2 .
[0032] The beneficial effect of adopting the above technical solution is that the screw hole 12 passes through the interior of the base 1, and its main function is to engage with the bolt through the interior, so that the base 1 is fixed, so that the base 1 not only has a load-bearing effect, but also maintains the overall stability of the device.
[0033] Among them, a ventilation hole 13 and a heat dissipation groove 14 are opened at the bottom end of the base 1, and a thermal conductive copper column 15 is fixedly installed inside the heat dissipation groove 14. There are multiple heat dissipation grooves 14 and multiple thermal conductive copper columns 15, which are all located on the outside of the ventilation hole 13.
[0034] The beneficial effect of adopting the above technical solution is that the ventilation hole 13 is located directly below the sphere 7. When the sphere 7 and the graphite column 8 rotate and rub inside the first mounting groove 2, a large amount of heat will be generated. At this time, the second mounting groove 3 allows the air inside the base 1 to circulate, thereby reducing the temperature inside the base 1, thereby increasing the service life of the device.
[0035] The plurality of heat-conducting copper pillars 15 are made of copper material, and the downward height of the plurality of heat-conducting copper pillars 15 is lower than the height of the plurality of heat dissipation slots 14 .
[0036] The beneficial effect of adopting the above technical solution is: the main function of the multiple heat-conducting copper columns 15 is to reduce the heat between the graphite column 8 and the base 1 by conducting the heat inside the base 1 to the outside due to the good thermal conductivity of copper, thereby increasing the life of the graphite column 8 and the base 1.
[0037] There are two second mounting grooves 3 , both of which are located inside the base 1 , and there are two springs 5 , both of which are located on the left and right sides of the sphere 7 .
[0038] The beneficial effect of adopting the above technical solution is that the two springs 5 will always provide elastic force to push the telescopic rod 4 toward the central axis direction of the first installation groove 2. When the sphere 7 needs to be installed, the sphere 7 is squeezed toward the bottom of the first installation groove 2. At this time, the telescopic rod 4 will shrink inward, thereby achieving the effect of facilitating installation.
[0039] There are two limiting sleeves 6 , which are respectively located on the left and right sides of the sphere 7 , and the extension lines on both sides of the two limiting sleeves 6 can surround and form a hollow circle.
[0040] The beneficial effect of adopting the above technical solution is: the main function of the two limit sleeves 6 is that when the sphere 7 is installed inside the first installation groove 2, the extension lines on both sides of the two limit sleeves 6 can be surrounded by a hollow circle, but the diameter value will be smaller than the maximum diameter value of the sphere 7. Therefore, when rotating, the sphere 7 will be limited up and down, thereby achieving convenient installation while maintaining the stability of the sphere 7.
[0041] There are a plurality of graphite columns 8 , and the plurality of graphite columns 8 are all located inside the first mounting groove 2 , and the plurality of graphite columns 8 are in contact with the inside of the base 1 respectively.
[0042] The beneficial effect of adopting the above technical solution is that the multiple graphite columns 8 will be driven by the sphere 7 to rotate. When the sphere 7 is rotating, some of the multiple graphite columns 8 will contact the inner wall of the base 1, and the surface of the graphite columns 8 is relatively smooth, and the contact area is a sphere protruding outward, so the contact area is small. Therefore, when the graphite columns 8 rub against the base 1, the friction force generated is small, so the wear generated is small, thereby improving the overall life of the sphere 7.
[0043] The working principle and use process of this utility model:
[0044] First, the base 1 is fixed to the designated component by engaging the bolts with the screw holes 12, so that the base 1 maintains overall stability, and at the same time, the diagonal support rod is inserted into the through hole 10, so that the ball 7 is connected to the diagonal support rod;
[0045] Secondly, the limiting sleeve 6 is pressed away from the central axis of the base 1 to shrink the telescopic rod 4 inward, and then the sphere 7 is placed in the first installation groove 2, and the limiting sleeve 6 is loosened. At this time, the extension lines on both sides of the two limiting sleeves 6 can surround a hollow circle, but the diameter value will be smaller than the maximum diameter value of the sphere 7, so that the sphere 7 can be limited up and down during rotation, thereby facilitating installation while maintaining the stability of the sphere 7;
[0046] At the same time, when support is needed, the graphite column 8 will follow the ball 7 to rotate inside the first mounting groove 2. At the same time, since the surface of the graphite column 8 is relatively smooth and the contact area is a spherical ball protruding outward, the contact area is small. Therefore, when the graphite column 8 and the base 1 rub against each other, the friction force generated is small, thereby improving the flexibility of the device.
[0047] Finally, since the device will generate a lot of heat when it is used for a long time and rubbed, when the heat cannot be discharged for a long time, it will affect the overall service life of the device. At this time, the ventilation holes 13 allow the internal air of the first mounting groove 2 to circulate, which has the effect of heat dissipation. At the same time, the thermal conductive copper column 15 can export the heat inside the base 1, thereby achieving the effect of improving the overall life of the device.
[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
