Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an anti-collision slider structure and an injection mold. Background Technology

[0002] In the field of injection molds, the demand for plastic products with metal inserts (such as terminals) is increasing in industries such as electronics and automotive parts. As a key mechanism for molds to achieve lateral demolding and form complex structures such as side recesses / side holes, the slider directly determines the molding quality of the product, the mold life and production efficiency.

[0003] For injection molded products that include terminals, plastic bodies, and shafts, metal terminals need to be pre-embedded in the mold cavity during the molding process. However, due to the difficulty in ensuring the implantation accuracy of the terminals, it is impossible to ensure that the terminals are completely and accurately in place each time injection is performed. During the forward movement of traditional sliders, they are prone to hard collisions with the terminals, which not only damages the sliders and terminals, increases mold maintenance costs and product scrap rates, but also causes frequent mold shutdowns, affecting production efficiency. Utility Model Content

[0004] The purpose of this application is to provide an anti-collision slider structure to solve the problem of collision between the slider and the terminal in the prior art; the purpose of this application is also to provide an injection mold including the anti-collision slider structure.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application provides an anti-collision slider structure, which includes a male mold core, a plurality of terminals, and at least one set of slider assemblies, wherein:

[0007] The male mold core is provided with a first mounting groove and several second mounting grooves. Several injection stations are arranged at intervals along the first horizontal direction in the first mounting groove. Each terminal is installed in the corresponding injection station. The slider assembly is arranged on the corresponding side of the first mounting groove extending along the first horizontal direction. The second mounting grooves extend along the second horizontal direction and are arranged one by one with the injection stations.

[0008] Each slider assembly includes a second slider, several first sliders, and several sets of elastic components. The second slider can move closer to or further away from the male mold core along a second horizontal direction. The first sliders can be reciprocated and disposed in the corresponding second mounting slots along the second horizontal direction. The first sliders can be raised and lowered and disposed on the side of the second sliders close to the first mounting slots. A single set of elastic components is disposed below a single second slider. The elastic components are configured to elastically lift the corresponding first sliders in the vertical direction to avoid interference between the first sliders and the bottom of the terminals along the second horizontal direction.

[0009] Optionally, the anti-collision slider structure also includes a base plate, which is set horizontally on the bottom surface of the male mold core. The elastic component includes at least one spring and at least one push rod. The bottom surface of a single second mounting groove is provided with at least one clearance channel, which extends vertically. The push rod is slidably set in the corresponding clearance channel in the vertical direction, and the top surface of the push rod slides against the bottom surface of the first slider.

[0010] The bottom end of the spring is connected to the base plate, and the top end of the spring is connected to the bottom of the corresponding top rod. The spring can be elastically compressed in the vertical direction.

[0011] Optionally, the elastic component includes two springs and two push rods, with two clearance channels provided on the bottom surface of a single second mounting slot, and the two push rods spaced apart along a second horizontal direction.

[0012] Optionally, the top of the push rod is provided with an inclined guide surface along the circumference, and the guide surface is inclined close to the top surface of the push rod.

[0013] Optionally, the first slider extends along the second horizontal direction and makes sliding contact with the sidewalls corresponding to the second mounting groove on both sides.

[0014] Optionally, the first slider has a first protrusion at one end near the second slider along the first horizontal direction, and the second slider has a first groove corresponding to the first protrusion. The first groove and the first protrusion are adapted to each other and both extend in the vertical direction. The first protrusion can be slidably disposed in the corresponding first groove in the vertical direction.

[0015] Optionally, both the first protrusion and the first groove are configured as "T" shaped.

[0016] Optionally, a second protrusion is provided on both sides of the bottom of the first slider extending along the second horizontal direction, and a second groove corresponding to the second protrusion is provided on the side wall of the second mounting groove. The second protrusion is slidably disposed in the corresponding second groove along the second horizontal direction. The second protrusion and the second groove extend along the second horizontal direction, and the height of the second groove is higher than the height of the second protrusion by a preset distance. The second groove is configured to limit the first slider in the vertical direction through the second protrusion.

[0017] An injection mold comprising any of the anti-collision slider structures described above.

[0018] Compared with the prior art, the anti-collision slider structure proposed in this application has the following advantages:

[0019] 1) By setting multiple sets of slider assemblies and elastic components in the male mold core and cooperating with them, the first slider can be elastically raised and lowered in the vertical direction, avoiding interference between the first slider and the bottom end of the terminal in the second horizontal direction, preventing hard collision between the two and causing damage, and ensuring production efficiency and production continuity.

[0020] 2) By adding a base plate and an elastic component consisting of a push rod and a spring below the male mold core, not only is the vertical elastic lifting of the first slider achieved with a simple structure, but the slider can also quickly return to its initial position after being subjected to force, avoiding jamming. At the same time, the push rod guides the slider to slide along the avoidance channel, ensuring the smoothness and controllability of the lifting and lowering action of the first slider.

[0021] 3) By providing second protrusions on both sides of the bottom of the first slider and providing corresponding second grooves on the side wall of the second mounting groove, the second protrusions slide along the second horizontal direction and the height of the grooves is higher than the preset distance of the protrusions, thus realizing the vertical direction limit of the first slider, limiting the maximum lifting distance of the first slider, avoiding the loss of control of the position of the first slider due to excessive deformation of the elastic component, and at the same time not affecting its horizontal movement, ensuring structural safety.

[0029] Please see Figures 1 to 5 As shown in the figure, an anti-collision slider structure provided in this application embodiment includes a male mold core 10, a plurality of terminals 20, and at least one set of slider assemblies 30, wherein:

[0030] Male mold core 10 along the first horizontal direction ( Figure 1 A first mounting groove 11 and several second mounting grooves 12 are centrally located in the direction of X. Several injection molding stations are spaced apart along a first horizontal direction within the first mounting groove 11. Each terminal 20 is correspondingly installed within an injection molding station. A slider assembly 30 is located on the corresponding side of the first mounting groove 11 extending along the first horizontal direction. The second mounting grooves 12 extend along a second horizontal direction... Figure 1 The Y-direction extends and is set up to correspond one-to-one with the injection molding stations;

[0031] Each slider assembly 30 includes a second slider 31, a plurality of first sliders 32, and a plurality of elastic components 33. The second slider 31 can move closer to or further away from the male mold core 10 along the second horizontal direction. The first slider 32 is reciprocally disposed in the corresponding second mounting groove 12 along the second horizontal direction. The first slider 32 is vertically disposed on the side of the second slider 31 close to the first mounting groove 11. A single set of elastic components 33 is disposed below a single second slider 31. The elastic components 33 are configured to elastically lift the corresponding first slider 32 in the vertical direction to avoid interference between the first slider 32 and the bottom end of the terminal 20 along the second horizontal direction.

[0032] Specifically, when the female mold core (not shown in the figure) is not pressed down, the second slider 31 moves a preset distance closer to the male mold core 10, so as to synchronously drive the first slider 32 to move closer to the terminal 20 along the second water direction to the first position. At this time, the bottom surface of the second slider 31 is higher than the upper surface of the bottom end of the terminal 20.

[0033] Specifically, a mold strip 40 is provided in the mounting groove, and a number of slots 41 are provided at intervals along the first horizontal direction. Each slot 41 corresponds to an injection molding station, and the terminal 20 is set in the corresponding slot 41.

[0034] By setting multiple sets of slider assemblies 30 and elastic components 33 in the male mold core 10 and cooperating with them, the first slider 32 can be elastically raised and lowered in the vertical direction, avoiding interference between the first slider 32 and the bottom end of the terminal 20 in the second horizontal direction, preventing hard collision between the two and causing damage, and ensuring production efficiency and production continuity.

[0035] In one embodiment, the anti-collision slider structure further includes a base plate 50, which is disposed horizontally on the bottom surface of the male mold core 10. The elastic component 33 includes at least one spring 330 and at least one push rod 331. The bottom surface of a single second mounting groove 12 is provided with at least one clearance channel 120, which extends vertically. The push rod 331 is slidably disposed vertically in the corresponding clearance channel 120, and the top surface of the push rod 331 slides against the bottom surface of the first slider 32.

[0036] The bottom end of the spring 330 is connected to the base plate 50, and the top end of the spring 330 is connected to the bottom of the corresponding top rod 331. The spring 330 can be elastically compressed in the vertical direction.

[0037] Specifically, a limiting surface 3310 is provided at the bottom of the ejector pin 331. The limiting surface 3310 interferes with the bottom surface of the male mold core 10 in the vertical direction. When the female mold core is not pressed down, the limiting surface 3310 abuts against the bottom surface of the male mold core 10, thus limiting the ejector pin in the vertical direction.

[0038] Specifically, a limiting groove 51 is provided on the base plate 50. The limiting groove 51 is adapted to the bottom of the spring 330. The spring 330 is installed in the limiting groove 51, and the bottom end of the spring 330 abuts against the bottom surface of the limiting groove 51. The limiting groove 51 is used to limit the spring 330 in the circumferential direction so that the spring 330 remains vertical.

[0039] By adding a base plate 50 and an elastic component 33 consisting of a push rod 331 and a spring 330 below the male mold core 10, not only is the vertical elastic lifting of the first slider 32 achieved with a simple structure, but the slider can also quickly return to its initial position after being subjected to force, avoiding jamming. At the same time, the push rod 331 guides the slider to slide along the avoidance channel 120, ensuring the smoothness and controllability of the lifting and lowering action of the first slider 32.

[0040] In one embodiment, the elastic component 33 includes two springs 330 and two push rods 331, and the bottom surface of a single second mounting groove 12 is provided with two clearance channels 120, and the two push rods 331 are spaced apart along the second horizontal direction.

[0041] By providing two springs 330 and two push rods 331 in the elastic component 33, and providing two clearance channels 120 on the bottom surface of the second mounting groove 12 with the push rods 331 spaced apart along the second horizontal direction, balanced elastic support for the first slider 32 is achieved, preventing the first slider 32 from tilting due to uneven force, ensuring the stability of its lifting direction, and improving the reliability of the anti-collision effect.

[0042] In one embodiment, the top end of the push rod 331 is provided with an inclined guide surface along the circumferential direction, and the guide surface is inclined near the top surface of the push rod 331.

[0043] By providing an inclined guide surface close to the top surface around the top of the push rod 331, smooth guidance is achieved when the first slider 32 contacts the push rod 331, reducing the frictional resistance between the first slider 32 and the push rod 331 during the reciprocating movement of the first slider 32 along the second horizontal direction, and avoiding jamming.

[0044] In one embodiment, the first slider 32 extends along the second horizontal direction and slides in contact with the sidewalls corresponding to the second mounting groove 12 on both sides.

[0045] By allowing the first slider 32 to slide and contact the side wall of the second mounting groove 12 along both sides of the second horizontal direction, the first slider 32 is precisely guided along the second horizontal direction, preventing the first slider 32 from deviating during movement and avoiding collision between the first slider 32 and the two ends of the terminal 20 along the first horizontal direction.

[0046] In one embodiment, a first protrusion 320 is provided at one end of the first slider 32 near the second slider 31 along a first horizontal direction, and a first groove 310 corresponding to the first protrusion 320 is provided on the second slider 31. The first groove 310 and the first protrusion 320 are adapted to each other and both extend in the vertical direction. The first protrusion 320 can be slidably disposed in the corresponding first groove 310 in the vertical direction.

[0047] By setting a sliding fit between the first protrusion 320 and the first groove 310, a liftable fit relationship is formed, so that the first slider 32 has a controllable stroke in the vertical direction, thereby improving the stability of the first slider 32 running in the vertical direction.

[0048] In one embodiment, both the first protrusion 320 and the first groove 310 are configured as "T" shaped.

[0049] By setting the first protrusion 320 and the first groove 310 to a "T" shape, a stable connection and guidance between the second slider 31 and the first slider 32 is achieved, preventing them from separating when moving relative to each other or horizontally, enhancing structural stability, and ensuring the reliable operation of the anti-collision mechanism.

[0050] In one embodiment, the bottom of the first slider 32 is provided with second protrusions 321 on both sides extending along the second horizontal direction. The side wall of the second mounting groove 12 is provided with a second groove 121 corresponding to the second protrusions 321. The second protrusions 321 are slidably disposed in the corresponding second grooves 121 along the second horizontal direction. The second protrusions 321 and the second grooves 121 extend along the second horizontal direction. The height of the second grooves 121 is higher than the height of the second protrusions 321 by a preset distance. The second grooves 121 are configured to limit the first slider 32 in the vertical direction through the second protrusions 321.

[0051] Specifically, when the female mold core is not pressed down, the top surface of the second protrusion 321 abuts against the top surface of the second groove 121. When the female mold core is not pressed down to abut against the male mold core 10, the bottom surface of the second protrusion 321 abuts against the bottom surface of the second groove 121. At this time, the first slider 32 and the second slider 31 continue to be pushed along the second horizontal direction until the second slider 31 abuts against the male mold core 10. At this time, the bottom surface of the first protrusion 320 near the terminal 20 is flush with the upper surface of the bottom end of the terminal 20 and moves to the second position along the second horizontal direction, which facilitates the precise processing of subsequent products.

[0052] By providing second protrusions 321 on both sides of the bottom of the first slider 32 and corresponding second grooves 121 on the side wall of the second mounting groove 12, the second protrusions 321 slide along the second horizontal direction and the height of the groove is higher than the preset distance of the protrusions, thus realizing the vertical positioning of the first slider 32, limiting the maximum lifting distance of the first slider 32, avoiding the loss of control of the position of the first slider 32 due to excessive deformation of the elastic component 33, and at the same time not affecting its horizontal movement, ensuring structural safety.

[0053] An injection mold comprising any of the anti-collision slider structures described above.

[0054] The working principle of the above-mentioned anti-collision slider structure is as follows:

[0055] S1, when the female mold core is not pressed down: the second slider 31 moves a preset distance along the second horizontal direction towards the male mold core 10, and simultaneously drives the first slider 32 to move along the second horizontal direction towards the terminal 20 to the first position; at this time, the elastic component 33 elastically lifts the first slider 32 in the vertical direction, so that the bottom surface of the second slider 31 is higher than the upper surface of the bottom end of the terminal 20 to avoid interference, and the top surface of the second protrusion 321 of the first slider 32 abuts against the top surface of the second groove of the second mounting groove 12.

[0056] S2, when the female mold core is pressed down to abut against the male mold core 10: the first slider 32 is lowered by the pressure of the female mold core to overcome the elastic force of the elastic component 33, the bottom surface of the first slider 32 near the terminal 20 is flush with the upper surface of the bottom end of the terminal 20, the bottom surface of the second protrusion 321 abuts against the bottom surface of the second groove, and the bottom of the terminal 20 abuts against the female mold core above.

[0057] S3, continue to advance the first slider 32 and the second slider 31 along the second horizontal direction until the second slider 31 abuts against the male mold core 10, and the first slider 32 moves to the second position on the terminal 20 along the second horizontal direction to complete the positioning, thus preparing for the subsequent precise processing of the product.

[0058] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
