It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present invention.

[0027] In addition, such terms as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meanings of "several" and "a number of" are two or more, unless otherwise specifically defined.

[0028] A drawer-type core-pulling structure wheel speed sensor injection mold, as Figures 1-4 shown, includes: an upper die holder 1, on which a profiling die cavity 3 and several positioning guide posts 4 are provided; a lower die holder 2, on which a fixed seat 7, a core-pulling seat 8 and several positioning guide holes 9 are provided. The several positioning guide holes 9 cooperate with the several positioning guide posts 4 for positioning. The top of the fixed seat 7 is provided with a chip die cavity 10 and a wire positioning groove 11. The inside of the fixed seat 7 is provided with a bushing die cavity. The side of the fixed seat 7 facing the core-pulling seat 8 is provided with an opening 18 communicating with the bushing die cavity. The core-pulling seat 8 is horizontally slidably connected to the lower die holder 2 and can move towards the fixed seat 7. The side of the core-pulling seat 8 facing the fixed seat 7 is provided with a bushing positioning die core 17, and the bushing positioning die core 17 can pass through the opening 18 and extend into the bushing die cavity.

[0029] Preferably, a sliding cavity 19 is provided on the lower die base 2, guiding grooves 15 are provided on both sides of the sliding cavity 19, the core pulling seat 8 is located in the sliding cavity 19, and sliding blocks 16 are provided on both sides of the core pulling seat 8. The sliding blocks 16 extend into the guiding grooves 15, thereby realizing the horizontal sliding connection of the core pulling seat 8 and the lower die base 2.

[0030] Preferably, a locking groove 13 is provided on the core pulling seat 8, a locking rod 5 is provided on the upper die base 1, and the locking rod 5 can extend into the locking groove 13 to lock the core pulling seat 8. Specifically, when the upper die base 1 and the lower die base 2 are closed, the locking rod 5 extends into the locking groove 13, causing the core pulling seat 8 to move a short distance towards the fixed seat 7 and be locked, thereby ensuring that the core pulling seat 8 does not move during injection molding.

[0031] Preferably, the locking rod 5 is distributed obliquely vertically, and the locking groove 13 is also distributed obliquely vertically.

[0032] Preferably, a wire sliding groove 12 is provided at the top of the core pulling seat 8. The wire sliding groove 12 is used to clamp and position the wire, and can also continue to maintain the guiding position when the core pulling seat 8 moves.

[0033] Preferably, a core pulling handle 14 is provided on the side of the core pulling seat 8 away from the fixed seat 7, so that the core pulling seat 8 can be pulled out through the core pulling handle 14, realizing the rapid extraction of the core pulling seat 8.

[0034] Preferably, a plurality of positioning blocks 6 are provided on the upper die base 1, a plurality of positioning grooves 20 are provided on the fixed seat 7, and the positioning blocks 6 can extend into the positioning grooves 20 for positioning. Specifically, by providing the positioning blocks 6 and the positioning grooves 20, when the upper die base 1 and the lower die base 2 are closed, the positioning blocks 6 can extend into the positioning grooves 20, thereby accurately ensuring the injection molding accuracy of the product during mold closing.

[0035] Operation process:

[0036] a. Install the sensor chip carrier in the chip cavity 10 of the fixed seat 7 of the lower die base 2, position the wire on the wire positioning groove 11 of the fixed seat 7 of the lower die base 2 and in the wire sliding groove 12 of the core pulling seat 8;

[0037] b. Keep the core pulling seat 8 in the pulled-out state, and install the metal bushing on the bushing positioning die core 17 of the core pulling seat 8;

[0038] c. Gently push the core pulling handle 14 of the core pulling seat 8. Under the guiding action of the sliding block 16 in the guiding groove 15, make the core pulling seat 8 fit with the fixed seat 7, and the bushing positioning die core 17 extends into the bushing cavity;

[0039] d. Start the injection molding machine to close the mold. Under the action of the combined force of the locking groove 13 of the core-pulling seat 8 and the locking rod 5 of the upper mold base 1, the core-pulling seat 8 moves a short distance towards the fixed seat 7 to achieve a gapless fit, thus meeting the requirement of no flash on the injection molded part.

[0040] e. After the injection molding and cooling are completed, the mold is opened. Under the action of the inclined locking rod 5 of the upper mold base 1, the core-pulling seat 8 on the lower mold base 2 retracts a short distance (meeting the mold opening stroke limit of small-tonnage machines), so as to separate the product and eject the product. Then, the worker manually takes away the injection molded part after injection molding.

[0041] f. At this time, the worker can easily pull out the core-pulling handle 14 until the slider 16 reaches the limit position, install the bushing on the core-pulling core, and perform the next injection molding (repeat step a).

[0042] Advantages:

[0043] 1. The overall structure of the mold design of the present utility model is delicate, flexible, and refined.

[0044] 2. It solves the technical problems of insufficient mold cavity size and maximum mold opening stroke of small-tonnage machines, and at the same time reduces the energy consumption of the machine.

[0045] 3. The ingenious design of the drawer-type new structure mold conforms to the principles of ergonomics.

[0046] 4. This structure can meet the injection molding of complex products with metal inserts such as wheel speed sensors.

[0047] 5. This structure can realize complex actions of driving structures such as replacing traditional oil cylinders, air cylinders, and electric drives with products with metal inserts such as wheel speed sensors.

[0048] 6. The mold design structure reduces the new mold development cost by about 30%, enhances the cost advantage of the development quotation for small demand in new projects, and enhances the cost quotation competition advantage of the company's new project products.
