Description

Technical Field

[0001] This utility model relates to the technical field of mold ejector pin processing equipment, and in particular to a mold ejector pin grinding mold. Background Technology

[0002] Ejector pins play a crucial role in mold manufacturing, including positioning, venting, core pulling, demolding, and preventing slippage. They are essential for the stability, accuracy, and product quality of the machining process. Due to the significant length variations in ejector pins, traditional machining methods are inefficient and struggle to guarantee precision. Therefore, specialized grinding molds are needed to improve machining accuracy and efficiency. An ejector pin grinding mold is a specialized piece of equipment used for machining and grinding ejector pins. It uses a clamping device to hold the ejector pins, and a motor drives the grinding disc or clamping device to automatically grind the ejector pins. This significantly reduces labor intensity, increases labor efficiency, lowers processing costs, and ensures synchronous rotation of the ejector pins in the same direction, increasing machining accuracy.

[0003] When using a clamp to hold ejector pins, the outer clamping plate is first opened, and then the ejector pins are placed into the arc-shaped groove of the inner clamping plate in sequence. The outer clamping plate is then tightened. The outer clamping plate and the inner clamping plate are fixed by hex socket screws. After loosening the hex socket screws, when inserting the ejector pin, it is necessary to push the outer clamping plate and the rubber pad between the two clamping plates to expose enough space in the arc-shaped groove for inserting the ejector pin. This is time-consuming and laborious. Therefore, it is necessary to provide a mold ejector pin grinding mold to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a mold ejector grinding mold to solve the problem mentioned in the background art, where the outer clamping plate and the inner clamping plate are fixed by hexagonal screws. After loosening the hexagonal screws, when inserting the ejector pin, it is necessary to push the outer clamping plate and the rubber pad between the two clamping plates to expose enough space in the arc groove for inserting the ejector pin, which is time-consuming and laborious.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a grinding mold for mold ejector pins, comprising:

[0007] A grinding mold includes a support block, a first clamping block, an arc-shaped groove, a second clamping block, and a rubber pad. The first clamping block is fixed to the side of the support block by an internal hex screw. The arc-shaped groove is opened on the side of the first clamping block and is evenly distributed. The second clamping block is fixed to the upper end of the side of the support block by an internal hex screw passing through the first clamping block. The rubber pad is sandwiched between the first clamping block and the second clamping block, and the internal hex screw passes through the rubber pad.

[0008] The ejection assembly includes a first fixing block, a second fixing block, a groove, a spring, an L-shaped retaining strip, and side ears. The first fixing block is fixed to the upper ends of both sides of the first clamping block, the second fixing block is fixed to both sides of the second clamping block, the grooves are respectively opened on the adjacent side of the first fixing block and the second fixing block, the two ends of the spring are respectively fixed in the grooves on the first fixing block and the second fixing block, the lower end of the L-shaped retaining strip is fixed to the lower end of the side of the second fixing block located in the groove, and the side ears are fixed to both ends of the rubber pad strip.

[0009] Furthermore, the lower end of the side lug is higher than the lower end of the rubber pad strip, and the side lug is inserted between the L-shaped clip and the second fixing block.

[0010] Furthermore, the grinding mold also includes an equipment base and a support platform, with the equipment base placed on the ground and the support platform fixed to the upper end of the equipment base.

[0011] Furthermore, the grinding mold also includes a slide table and a clamping table. The slide table is slidably connected to the upper end of the support table, the clamping table is fixed to the middle of the upper end of the support table, and the support block is fixed to the middle of the upper end of the clamping table.

[0012] Furthermore, the tops of the first clamping block and the second clamping block are on the same plane, with the top of the first clamping block being higher than the support block.

[0013] Furthermore, it also includes a quick-connect component, which includes a connecting shaft and a limiting plate. One end of the connecting shaft is fixed to the upper side of the support block, and both ends of the limiting plate are rotatably connected to the connecting shaft.

[0014] Furthermore, the quick assembly also includes a third fixing block, a torsion spring, and an L-shaped support plate. One end of the third fixing block is fixed to the side of the first fixing block away from the groove, and the side of the third fixing block is fixed to the other end of the connecting shaft. One end of the L-shaped support plate is sleeved on the connecting shaft, and the other end is fixed to both ends of the limiting plate. The torsion spring is sleeved on one end of the connecting shaft, and one end of the torsion spring is fixed to the side of the third fixing block, and the other end is fixed to the side of the L-shaped support plate.

[0015] Furthermore, when the limiting plate moves onto the first clamping block, it is located on the side above the arc groove. When the limiting plate is attached to the upper surface of the support block, the upper end is lower than the top of the first clamping block.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] I. This utility model, through the set ejector component, loosens the hexagonal screw on the second clamping block without causing it to fall off the first clamping block. As the hexagonal screw is turned, the spring in the side groove of the first fixing block extends, pushing the second fixing block away from the first fixing block, thereby causing the second clamping block to move away from the first clamping block. At the same time, the side lug in the L-shaped retaining strip moves accordingly, simultaneously causing the rubber pad to move away from the first clamping block. At this time, the ejector pin can be placed into the arc-shaped groove. This setting can make the second clamping block and the rubber pad move away from the first clamping block while loosening the hexagonal screw, saving the time of pushing the second clamping block and the rubber pad.

[0018] II. In this utility model, through the set quick component, after the second clamping block is opened, the limiting plate is pulled, which drives the L-shaped support plate to rotate around the connecting shaft on the side of the third fixed block until the limiting plate rotates 90 degrees and is perpendicular to the upper end of the first clamping block. The sides of these limiting plates are exactly on the upper side of the arc groove. Holding the ejector pin, it is placed downward into the arc groove while adhering to the limiting plate. This setting can save some of the time for adjusting the position of the ejector pin and improve the grinding efficiency. Attached Figure Description

The rubber pad 18 is sandwiched between the first clamping block 15 and the second clamping block 17, and the internal hex screw passes through the rubber pad 18.

[0031] The grinding mold also includes an equipment base 10 and a support platform 11. The equipment base 10 is placed on the ground, and the support platform 11 is fixed to the upper end of the equipment base 10.

[0032] The grinding mold also includes a slide table 12 and a fixture table 13. The slide table 12 is slidably connected to the upper end of the support table 11, the fixture table 13 is fixed to the middle of the upper end of the support table 11, and the support block 14 is fixed to the middle of the upper end of the fixture table 13.

[0033] The tops of the first clamping block 15 and the second clamping block 17 are on the same plane, and the top of the first clamping block 15 is higher than the support block 14.

[0034] The equipment base 10 provides support, the support platform 11 provides support and facilitates the movement of the slide 12. The slide 12 provides support and drives the clamping platform 13 to move. The clamping platform 13 is used to receive clamps. The support block 14 is used to fix the clamps. The first clamping block 15 and the second clamping block 17 are used to clamp the ejector pins. The arc groove 16 is used to accommodate the ejector pins. The rubber pad 18 can make the ejector pins clamp more stably.

[0035] The ejection assembly includes a first fixing block 20, a second fixing block 21, a groove 22, a spring 23, an L-shaped retaining strip 24, and a side lug 25. The first fixing block 20 is fixed to the upper ends of both sides of the first clamping block 15, the second fixing block 21 is fixed to both sides of the second clamping block 17, the grooves 22 are respectively opened on the side adjacent to the first fixing block 20 and the second fixing block 21, the two ends of the spring 23 are respectively fixed in the grooves 22 on the first fixing block 20 and the second fixing block 21, the lower end of the L-shaped retaining strip 24 is fixed to the lower end of the side of the second fixing block 21 located in the groove 22, and the side lug 25 is fixed to both ends of the rubber pad strip 18.

[0036] The lower end of the side ear 25 is higher than the lower end of the rubber pad strip 18, and the side ear 25 is inserted between the L-shaped clip strip 24 and the second fixing block 21;

[0037] The first fixing block 20 and the second fixing block 21 provide support, the groove 22 provides connection, the spring 23 has a telescopic function, the L-shaped locking strip 24 provides connection and limit, and the side lug 25 provides connection.

[0038] Working principle:

[0039] Loosen the hex screw on the second clamping block 17 so that it does not fall off the first clamping block 15. As the hex screw is turned, the spring 23 in the side groove 22 of the first fixing block 20 extends, pushing the second fixing block 21 away from the first fixing block 20, thereby moving the second clamping block 17 away from the first clamping block 15. At the same time, the side lug 25 in the L-shaped retaining strip 24 moves accordingly, and at the same time, the rubber pad strip 18 moves away from the first clamping block 15. At this time, the ejector pin can be placed into the arc-shaped groove 16.

[0040] This step allows the second clamping block 17 and the rubber pad 18 to move away from the first clamping block 15 while loosening the hex screws, saving time in pushing the second clamping block 17 and the rubber pad 18.

[0041] Please see Figure 2 , Figure 4 This embodiment, based on the above embodiments, further includes:

[0042] The quick assembly includes a connecting shaft 31 and a limiting plate 34. One end of the connecting shaft 31 is fixed to the upper side of the support block 14, and both ends of the limiting plate 34 are rotatably connected to the connecting shaft 31.

[0043] The quick assembly also includes a third fixing block 30, a torsion spring 32, and an L-shaped support plate 33. One end of the third fixing block 30 is fixed to the side of the first fixing block 20 away from the groove 22, and the side of the third fixing block 30 is fixed to the other end of the connecting shaft 31. One end of the L-shaped support plate 33 is sleeved on the connecting shaft 31, and the other end is fixed to both ends of the limiting plate 34.

[0044] When the limiting plate 34 moves onto the first clamping block 15, it is located on the side above the arc groove 16. When the limiting plate 34 is in contact with the upper surface of the support block 14, the upper end of the limiting plate 34 is lower than the top of the first clamping block 15.

[0045] The third fixing block 30 provides support, the connecting shaft 31 facilitates the rotation of the L-shaped support plate 33, the torsion spring 32 has a reset function, the L-shaped support plate 33 provides connection, and the limiting plate 34 provides positioning.

[0046] Working principle:

[0047] After opening the second clamping block 17, pull the limiting plate 34, causing the L-shaped support plate 33 to rotate around the connecting shaft 31 on the side of the third fixing block 30 until the limiting plate 34 rotates 90 degrees and is perpendicular to the upper end of the first clamping block 15. The sides of these limiting plates 34 are exactly above the side of the arc groove 16. Hold the pin and place the limiting plate 34 downward into the arc groove 16. After all the pins are in place, release the limiting plate 34. Under the action of the torsion spring 32, the limiting plate 34 rotates 90 degrees in the opposite direction and fits against the support block 14.

[0048] This step can save some time in adjusting the position of the ejector pin and improve grinding efficiency.
