Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a slider structure that prevents damage to the tiny pins of electronic components. Background Technology

[0002] In the automotive parts manufacturing industry, the manufacturing process for automotive temperature sensor components has extremely stringent requirements. Because the two pins on the temperature sensor are very thin, approximately 0.3 mm in diameter, and are exposed within the plastic part's support column, the injection mold design typically only allows for the use of a slider to achieve the subsequent overmolding process. However, after the pre-injection part is inserted, the temperature sensor's position is unstable, often exhibiting lateral sway. This situation causes significant problems for subsequent overmolding. Since the slider cannot effectively position and protect the unstable and delicate temperature sensor pins during operation, the two pins are frequently damaged by the slider. Once the pins are damaged, the performance of the temperature sensor is severely affected, resulting in an extremely low yield rate in overmolding production. Utility Model Content

[0003] In view of this, in order to solve the above problems, the purpose of this utility model is to provide a slider structure to prevent damage to the small pins of electronic components, including: a fixed mold core, a pre-injection part, a left slider and a right slider, wherein the pre-injection part is disposed on the fixed mold core, and the left slider and the right slider are slidably disposed on the fixed mold core, and the left slider and the right slider are disposed on both sides of the pre-injection part.

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0017] like Figure 1-2 As shown, a preferred embodiment of a slider structure for preventing damage to small leads of electronic components is illustrated, comprising: a fixed mold core 1, a pre-injection part 2, a left slider 3, and a right slider 4. The pre-injection part 2 is disposed on the fixed mold core 1, and the left slider 3 and the right slider 4 are slidably disposed on the fixed mold core 1, with the left slider 3 and the right slider 4 disposed on both sides of the pre-injection part 2.

[0018] Furthermore, as a preferred embodiment, both the left slider 3 and the right slider 4 have guide slopes on the sides that are close to each other.

[0019] Furthermore, as a preferred embodiment, the left slider 3 includes: a first insert and a second insert, wherein the second insert is disposed between the two first inserts and connects the two second inserts.

[0020] Furthermore, as a preferred embodiment, the first insert has a first slot on the side near the right slider 4, and the second insert has a first locking block on the side near the right slider 4.

[0021] Furthermore, as a preferred embodiment, the right slider 4 includes a third insert and a fourth insert, the fourth insert being disposed between the two third inserts and connecting the two third inserts, the third insert cooperating with the first insert, and the fourth insert cooperating with the second insert.

[0022] Furthermore, in a preferred embodiment, the third insert has a second locking block on the side near the first insert, and the fourth insert has a second slot on the side near the second insert. The first locking block cooperates with the second slot, and the second locking block cooperates with the first slot.

[0023] Furthermore, in a preferred embodiment, there is a certain angle between the sidewall of the first card block and the inner sidewall of the second slot, as well as between the sidewall of the second card block and the inner sidewall of the first slot. This angle allows the pressure to be evenly distributed around the pins of the temperature sensor, preventing stress concentration at a single point and thus protecting the pins from damage.

[0024] Furthermore, as a preferred embodiment, the included angle is preferably set to 2°.

[0025] Furthermore, in a preferred embodiment, the first slot, the first card block, the second slot, and the second card block all have guide ramps. The guide ramps provide guidance; when the left slider 3 and the right slider 4 begin to slide, the guide ramps gradually guide the temperature sensor pins to move to the correct position. Because the slope of the guide ramps is relatively gentle, hard collisions with the pins are avoided during the guiding process, effectively preventing damage to the pins.

[0026] The working principle of this utility model is as follows: In use, the pre-injection part 2 is first installed on the fixed mold core 1. When the injection process begins, the left slider 3 and the right slider 4 slide towards each other along the fixed mold core 1. At this time, the guide slope on the side where the left slider 3 and the right slider 4 are close to each other begins to function. Since the angle between the guide slope and the pin of the temperature sensor in the pre-injection part 2 is relatively gentle, when the left slider 3 and the right slider 4 approach the pin, the guide slope gently touches the pin. As the left slider 3 and the right slider 4 continue to slide, the pin gradually moves towards the preset position under the guidance of the guide slope. When the left slider 3 and the right slider 4 continue to slide towards each other and approach the sealing stage, the left slider 3 and the right slider 4 begin to work together. The first slot on the side of the left slider 3 where the first insert is close to the right slider 4, and the first locking block on the side of the second insert on the right slider 4, interact with the corresponding structure of the right slider 4. The second locking block on the side of the right slider 4 where the third insert is close to the first insert. The fourth insert, near the second insert, has a second slot that engages with the corresponding part of the left slider 3. As the left slider 3 and right slider 4 move closer, the first locking block gradually approaches the second slot, and the second locking block gradually approaches the first slot. Since there is a certain angle between the side wall of the first locking block and the inner side wall of the second slot, and between the side wall of the second locking block and the inner side wall of the first slot, and guide slopes are provided on the first slot, the first locking block, the second slot, and the second locking block, the guide slopes play a guiding role during the engagement process, allowing the locking blocks to enter the slot more accurately and smoothly. When the left slider 3 and right slider 4 complete the above engagement, achieving precise positioning and pressure dispersion of the temperature sensor pins, the left slider 3 and right slider 4 continue to move until the sealing action is completed. At this time, the temperature sensor pins are stably and safely fixed in the correct position, and the encapsulation injection molding can proceed smoothly, effectively avoiding damage to the pins during the injection molding process, thereby improving the product yield.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
