Description

Technical Field

[0001] The utility model relates to the field of plastic molding molds, in particular to a mechanism for facilitating the installation of inserts. Background Art

[0002] Many plastic products currently on the market are integrally formed through plastic molds, and some are integrally formed by placing inserts into the mold.

[0003] Insert products are generally used in products with force requirements or conductive requirements. Installing the insert in the plastic mold and injecting it together with the plastic can improve the strength and service life of the product. Existing plastic mold insert positioning cores are designed according to the tolerance of the insert, and are specifically designed according to the upper limit of the insert tolerance (because the insert tolerance band is relatively large). The fit between the insert and the positioning core is a clearance fit, and the insert is usually processed to eliminate tolerance through a slider structure or a spring structure. For inserts that need to be positioned in multiple directions, the mold design structure is relatively complex, and the insert will be difficult to place in the mold, with the risk of inaccurate positioning or crushing.

[0004] As attached Figure 1 The long side wall of the insert shown in the figure can be well processed by the slider structure to eliminate tolerance, but the left and right sides are not easy to eliminate tolerance. Therefore, a mechanism with a simple structure and no damage to the insert is urgently needed. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a mechanism for facilitating installation of inserts.

[0006] The technical solution adopted by the utility model to solve the technical problem is: a mechanism for facilitating the installation of an insert, which includes:

[0007] A first component, the first component is provided with a first core;

[0008] A second component, wherein a groove is provided on one side of the second component facing the first component, and a short side wall of the insert is sleeved on a side wall of the groove. The second component comprises a rotatable clamping core, and an outer side of the short side wall of the insert is located on a motion track of the clamping core;

[0009] During the mold closing process, the first core drives the clamping core to rotate.

[0010] With this structural setting, since the clamping core can rotate, when placing the insert, the force of the insert will drive the clamping core to rotate, thereby increasing the size of the groove. Therefore, the insert can be easily placed in the mold, and the insert is not easily crushed on the surface. Secondly, during the mold closing process, the first core drives the clamping core to rotate, causing the clamping core to rotate toward the insert, thereby achieving a clamping and fixing effect of the insert, eliminating insert tolerance, and improving the accuracy of insert installation.

[0011] Wherein, the first core is provided with an inclined surface at one end facing the clamping core or the clamping core is provided with an inclined surface at one end facing the first core; or, the first core is provided with an inclined surface at one end facing the clamping core and the clamping core is provided with an inclined surface at one end facing the first core.

[0012] Through the effect of beveling, the clamping core is rotated, thereby achieving a clamping effect.

[0013] The second component further comprises a positioning core and a reverse locking core, and the positioning core and the reverse locking core cooperate to form a groove.

[0014] The positioning core cooperates with the anti-lock core to form an assembly through two independent accessories, which reduces the processing difficulty.

[0015] Wherein, the clamping core and the positioning core are rotationally connected.

[0016] The clamping core is rotatably connected to the positioning core to form a rotation effect of the clamping core. Here, the clamping core can also be rotatably connected to the anti-locking core.

[0017] Wherein, a support foot is provided at one end of the clamping core away from the first core, and one end of the support foot away from the first core is a rotation connection with the positioning core.

[0018] The setting of the support foot lengthens the rotating connection of the clamping core, thereby enlarging the rotating stroke of the clamping core, thereby achieving the effect of clamping the insert.

[0019] The clamping core cooperates with the anti-locking core to form a driving groove, and the first core is provided with a driving protrusion, which extends into the driving groove.

[0020] The setting of the driving groove enables the first core to move, thereby achieving better driving and fixing effects.

[0021] The first component further comprises a second core, one of the second core and the clamping core is provided with a first positioning protrusion, and the other of the second core and the clamping core is provided with a first positioning groove matched with the first positioning protrusion.

[0022] The cooperation between the first positioning protrusion and the first positioning groove forms a positioning and fixing effect, thereby preventing movement and improving the clamping effect of the clamping core.

[0023] Among them, one of the second core and the positioning core is provided with a second positioning protrusion, and the other of the second core and the positioning core is provided with a second positioning groove matched with the second positioning protrusion.

[0024] The cooperation between the second positioning protrusion and the second positioning groove enables the second core to cooperate with the positioning core and the clamping core at the same time, thereby achieving a positioning and fixing effect.

[0025] The utility model further comprises a fixed mold module and a movable mold module, wherein the first component is accommodated in the fixed mold module and the second component is accommodated in the movable mold module.

[0026] The first component and the second component are separated into two modules, so that the cooperation is more stable during the driving process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1:

[0033] A mechanism for facilitating installation of inserts, such as the attached Figure 2-5 As shown, including:

[0034] The first component is provided with a first core 11, and the first core 11 cooperates with the first component to form a linkage effect. The first core 11 moves vertically, and can move vertically downward or vertically downward, and those skilled in the art can adjust it according to actual needs.

[0035] The second component, the first component and the second component are distributed up and down, the first component can be located at the top and the second component can be located at the bottom, or the first component can be located at the bottom and the second component can be located at the top. The second component is provided with a groove 12 on the side facing the first component, and the short side wall of the insert 20 is sleeved on the inner side wall of the groove 12. The second component includes a rotatable clamping core 13, and the clamping core 13 can rotate relative to the remaining components of the second component. The outer side of the short side wall of the insert 20 is located on the movement trajectory of the clamping core 13, that is, the side wall of the groove 12 cooperates with the clamping core 13 to achieve the clamping effect of the short side wall of the insert 20.

[0036] During the mold closing process, the first core 11 cooperates with the clamping core 13, and the first core 11 drives the clamping core 13 to rotate, thereby achieving a clamping effect.

[0037] It should also be noted that the first component and the second component only cooperate with one of the short side walls of the insert 20 to form a clamping and fixing effect. In actual use, there are two groups of first components and two groups of second components, which respectively cooperate with the two short side walls of the insert 20 to form a clamping and fixing effect.

[0038] With this structural setting, since the clamping core 13 can rotate, when placing the insert 20, the force of the insert 20 will drive the clamping core 13 to rotate outward, so that the size of the groove 12 is increased, so that the insert 20 can be easily placed in the mold, and the insert 20 is not prone to surface compression. Secondly, during the mold closing process, the first core 11 drives the clamping core 13 to rotate, so that the clamping core 13 rotates toward the insert 20, thereby achieving the clamping and fixing effect of the insert 20, eliminating the tolerance of the insert 20, and improving the accuracy of the installation of the insert 20.

[0039] Specifically, as attached Figure 3-5 As shown, the first core 11 is provided with an inclined surface toward one end of the clamping core 13 or the clamping core 13 is provided with an inclined surface toward one end of the first core 11. It can be that the first core 11 is provided with an inclined surface, so when the mold is closed, under the action of the inclined surface, a bevel effect is formed, so that the clamping core 13 rotates; it can also be that the clamping core 13 is provided with an inclined surface, which also forms a bevel effect, so that the clamping core 13 rotates; it can also be that the first core 11 and the clamping core 13 are both provided with inclined surfaces, and the two inclined surfaces cooperate to better achieve the rotation effect of the clamping core 13. Through the effect of bevel cutting, the clamping core 13 rotates, thereby achieving a clamping effect. In addition, a protrusion or a bump can be provided on the first core 11 to form an extrusion drive effect.

[0040] Specifically, as attached Figure 3-5 As shown, the second component also includes a positioning core 14 and a reverse locking core 15, and the positioning core 14 and the reverse locking core 15 are fitted at one end away from the first component. In this embodiment, the first component is located at the top and the second component is located at the bottom. Therefore, the positioning core 14 fits the lower end of the reverse locking core 15, and the upper ends of the positioning core 14 and the reverse locking core 15 cooperate to form a groove 12, and the clamping core 13 rotates relative to the groove 12. The positioning core 14 cooperates with the reverse locking core 15 to form an assembly through two independent accessories, which reduces the difficulty of processing.

[0041] Specifically, as attached Figure 3-5As shown, the clamping core 13 and the positioning core 14 are rotationally connected. The end of the clamping core 13 away from the first component cooperates with the positioning core 14 to form a rotational connection effect. The clamping core 13 and the positioning core 14 are rotationally connected to form a rotation effect of the clamping core 13. Here, the clamping core 13 can also be rotationally connected to the anti-locking core 15. In addition, it should be noted that the rotation distance of the clamping core 13 is limited by the anti-locking core 15, and the upper side wall of the anti-locking core 15 is located on the rotation trajectory of the clamping core 13.

[0042] Specifically, as attached Figure 3-5 As shown, the end of the clamping core 13 away from the first core 11 is provided with a support leg 131, and the support leg 131 extends obliquely downward, and here extends obliquely downward toward the side away from the anti-locking core 15. The end of the support leg 131 away from the first core 11 is a rotation connection with the positioning core 14. The provision of the support leg 131 lengthens the rotation connection of the clamping core 13, thereby enlarging the rotation stroke of the clamping core 13, thereby achieving the effect of clamping the insert 20.

[0043] Specifically, as attached Figure 3-5 As shown, the clamping core 13 cooperates with the anti-locking core 15 to form a driving groove 16, and the first core 11 is provided with a driving protrusion 111, which extends into the driving groove 16. The setting of the driving groove 16 allows the first core 11 to move, and better achieves the driving and fixing effects. In the initial state, the clamping core 13 is moved by the inclined surface, and then the driving protrusion 111 cooperates with the driving groove 16, so that the clamping core 13 is completely rotated toward one side of the insert 20, forming a clamping fit effect, and at the same time, the driving protrusion 111 and the driving groove 16 also form a limit fixing effect.

[0044] Specifically, as attached Figure 3-5 As shown, the first component also includes a second core 17, and one of the second core 17 and the clamping core 13 is provided with a first positioning protrusion 18, and the other of the second core 17 and the clamping core 13 is provided with a first positioning groove 19 that cooperates with the first positioning protrusion 18. The cooperation between the first positioning protrusion 18 and the first positioning groove 19 forms a positioning and fixing effect, prevents movement, and improves the clamping effect of the clamping core 13. When the second core 17 is provided with the first positioning protrusion 18, the clamping core 13 is provided with the first positioning groove 19; conversely, when the second core 17 is provided with the first positioning groove 19, the clamping core 13 is provided with the first positioning protrusion 18. Here, it is also necessary to explain that when the second core 17 is provided with a first positioning protrusion 18, the bottom surface of the first positioning protrusion 18 is higher than the bottom surface of the driving protrusion 111, that is, the driving protrusion 111 first squeezes the clamping core 13 so that the tolerance between the clamping core 13 and the insert 20 is eliminated. At this time, the first positioning protrusion 18 cooperates with the first positioning groove 19 to form a positioning and fixing effect.

[0045] Specifically, as attached Figure 3-5 As shown, one of the second core 17 and the positioning core 14 is provided with a second positioning protrusion 21, and the other of the second core 17 and the positioning core 14 is provided with a second positioning groove 22 that cooperates with the second positioning protrusion 21. The cooperation between the second positioning protrusion 21 and the second positioning groove 22 enables the second core 17 to cooperate with the positioning core 14 and the clamping core 13 at the same time, forming a positioning and fixing effect. When the second core 17 is provided with the second positioning protrusion 21, the positioning core 14 is provided with the second positioning groove 22; conversely, when the second core 17 is provided with the second positioning groove 22, the positioning core 14 is provided with the second positioning protrusion 21. Here, the bottom surface heights of the first positioning protrusion 18 and the second positioning protrusion 21 are consistent.

[0046] Specifically, as attached Figure 2 As shown, it also includes a fixed mold module 23 and a movable mold module 24, the first component is accommodated in the fixed mold module 23, and the second component is accommodated in the movable mold module 24. The first component and the second component are arranged in two modules, so that the cooperation is more stable during the driving process. In addition, the first component can also be accommodated in the movable mold module 24, and the second component can be accommodated in the fixed mold module 23. Those skilled in the art can adjust according to actual needs.

[0047] Specifically, as attached Figure 2-4 As shown, the mold also includes a slider 25, which is used to cooperate with the long side of the insert 20. The slider 25 cooperates with the driving source to form a horizontal movement effect, thereby forming a clamping and fixing effect of the long side of the insert 20 against each other. This is a prior art, so it is not described in detail in this embodiment.
