Description

Technical Field

[0001] This application belongs to the field of ejector pin processing technology, specifically relating to a mold ejector pin processing fixture. Background Technology

[0002] Ejector pins are used to eject molded products from a mold. Traditional ejector pins consist of a cylindrical ejector pin rod and a cylindrical ejector pin countersunk head integrated with the cylindrical ejector pin rod. The cylindrical ejector pin countersunk head is located at one end of the cylindrical ejector pin rod, and the cylindrical ejector pin is a cylinder with an equal outer diameter. Ejector pins of this structure are installed in the ejector pin mounting hole in the mold. When it is necessary to eject the molded product, the ejector pin rod of the ejector pin extends out from the mounting hole.

[0003] For example, patent CN 106003489 A provides a pin fixture, which includes a first mounting plate, a second mounting plate, and a connector. The connector is connected between the first mounting plate and the second mounting plate. The first mounting plate has at least two first mating holes, and the second mounting plate has at least two second mating holes. Each of the first mating holes and each of the second mating holes is coaxially connected to form at least two pin mating holes for inserting pins. The axes of the pin mating holes are parallel to each other. However, the aforementioned patent's heavy base plate fixation prevents adjustment of the pin height, making it unsuitable for various processing applications. Utility Model Content

[0004] This application provides a mold ejector pin machining fixture to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is: a mold ejector pin processing fixture, including a base plate, a clamping plate and a plurality of ejector pins arranged in an array on the base plate; the base plate and the clamping plate are connected by a sliding adjustment plate on both sides, and the clamping plate is provided with a plurality of pin holes corresponding to the ejector pins; a lower cover plate is provided below the base plate, and guide posts are vertically fixed at the four corners of the base plate, with the ends of the guide posts sleeved on the four corners of the clamping plate.

[0006] Furthermore, the sliding adjustment plate includes a rectangular strip, with a first strip groove in the middle of the rectangular strip that is parallel to the ejector pin, and a second strip groove at the bottom of the rectangular strip that is parallel to and symmetrical to the first strip groove.

[0007] Furthermore, the length of the first strip slot is greater than the length of the second strip slot.

[0008] Furthermore, the clamping plate has through holes at its four corners, and sleeves are provided in the through holes. The sleeves are slidably fitted onto the guide posts. Connecting blocks are provided at the bottom of both sides of the clamping plate. A first threaded hole is provided on the outside of the connecting block. A first fixing bolt for engaging the first strip-shaped slot is provided in the first threaded hole.

[0009] Furthermore, the base plate has second threaded holes on both sides, and the second threaded holes are provided with second fixing bolts for engaging the second strip-shaped slot.

[0010] Furthermore, a limiting post is provided in the base plate between the ejector pin and the sliding adjustment plate.

[0011] The beneficial effects of this application are: the height of the clamping plate and the base plate can be adjusted by sliding adjustment plate according to the needs of production and processing, and fixed by first bolt and second bolt. Then, when processing mold ejector pins, the height of the ejector pin can be adjusted according to actual needs. Then, the mold ejector pin is clamped by movable clamp and fixed clamp, so as to realize the batch processing of ejector pins of the same length. The overall clamping is convenient and quick, and the total length accuracy of the batch processed ejector pins is relatively stable. Attached Figure Description

Detailed Implementation

[0013] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0014] like Figure 1-3 As shown, this application provides a mold ejector pin 3 machining fixture, including a base plate 1, a clamping plate 2, and a plurality of ejector pins 3 arranged in an array on the base plate 1; the base plate 1 and the clamping plate 2 are connected by a sliding adjustment plate 4 on both sides, and the clamping plate 2 has a plurality of pin holes 21 corresponding to the ejector pins 3; a lower cover plate 5 is provided below the base plate 1, and guide posts 6 are vertically fixed at the four corners of the base plate 1, with the ends of the guide posts 6 sleeved at the four corners of the clamping plate 2. The base plate 1 of this application has a plurality of arrayed insertion holes, and a plurality of ejector pins 3 of the same length are inserted into the insertion holes, wherein the top of the ejector pin 3 can pass through the pin holes 21 of the clamping plate 2 for batch machining of the ejector pins 3, and the sliding adjustment plate 4 can adjust the distance between the base plate 1 and the clamping plate 2 to make the overall clamping convenient and quick.

[0015] The sliding adjustment plate 4 includes a rectangular strip 41. A first strip groove 42, parallel to the ejector pin 3, is provided in the middle of the rectangular strip 41. A second strip groove 43, parallel and symmetrically arranged to the first strip groove 42, is provided at the bottom of the rectangular strip 41. In the above design, the first strip groove 42 is used to connect the clamping plate 2, and the second strip groove 43 is used to connect the base plate 1.

[0016] The length of the first strip slot 42 is greater than the length of the second strip slot 43. In the above design, the first strip slot 42 is longer, which allows the clamping plate 2 to have a larger height adjustment distance, while the base plate 1 has a smaller adjustment distance.

[0017] The clamping plate 2 has through holes 22 at its four corners, and sleeves 23 are installed in the through holes 22. The sleeves 23 are slidably fitted onto the guide posts 6. Connecting blocks 24 are located at the bottom of both sides of the clamping plate 2. First threaded holes 25 are located on the outer sides of the connecting blocks 24, and first fixing bolts 7 are installed in the first threaded holes 25 for engaging the first strip-shaped groove 42. The sleeves 23 in this design facilitate the clamping plate 2 to move up and down along the guide post 6, allowing for flexible processing of the height of each ejector pin 3. Simultaneously, the first fixing bolts 7, along with the clamping plate 2, can move up and down along the first strip-shaped groove 42, thereby adjusting the height of the clamping plate 2.

[0018] The base plate 1 has second threaded holes 11 on both sides, and second fixing bolts 8 for engaging the second strip-shaped groove 43 are provided in the second threaded holes 11. In the above design, the second fixing bolts 8 can move the base plate 1 up and down along the second strip-shaped groove 43, thereby changing the height of the ejector pin 3 to adapt to different processing requirements.

[0019] A limiting post 9 is provided in the base plate 1 between the ejector pin 3 and the sliding adjustment plate 4. The limiting post 9 in the above design can ensure that the clamping plate 2 is in the lowest position, thereby preventing the clamping plate 2 from contacting the base plate 1.

[0020] The specific working principle is as follows: Loosen the first fixing bolt 7 and the second fixing bolt 8, adjust the position of the base plate 1 and the clamping plate according to actual needs, thereby adjusting the height of the ejector pin 3 according to actual needs, and then use the movable clamping seat and the fixed clamping seat to clamp the mold ejector pin 3, so as to realize the batch processing of ejector pins of the same length. The overall clamping is convenient and quick, and the overall length accuracy of the batch processed ejector pin 3 is relatively stable.

[0021] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
