Description

Technical Field

[0001] The utility model relates to the technical field of thimble processing, in particular to an adjustable thimble processing jig. Background Art

[0002] Ejectors are mostly standard parts. When used with molds, they need to be processed according to the product and fixed. When fixing the ejector, the current fixture uses a clamp to directly lock it. This is not convenient for online adjustment, and there are few clamping stations, which is not convenient for expansion and has low clamping efficiency. Therefore, we propose an adjustable ejector processing fixture. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an adjustable ejector pin processing jig.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] An adjustable ejector pin processing jig includes a base and an ejector pin. The base is U-shaped, and a baffle for limiting one end of the ejector pin is fixed to one end of the base by a first screw. A slide is slidably mounted on the base, and a first V-shaped groove and a second V-shaped groove for placing the ejector pin are formed on the top of the slide. A pressure block for pressing the ejector pin is fixed to the slide by a third screw.

[0006] Preferably, a limiting boss is fixed on one side of the slide close to the baffle for preventing the slide from colliding with the baffle.

[0007] Preferably, guide bars are fixed on both sides of the base by second screws, and sliding grooves are provided on both sides of the slide seat, and the guide bars are slidably installed in the sliding grooves.

[0008] Preferably, the first V-shaped grooves and the second V-shaped grooves are arranged at equal distances.

[0009] Preferably, two first V-shaped grooves and two second V-shaped grooves are provided between adjacent positioning blocks in any row.

[0010] Preferably, two rows of equally spaced positioning blocks are fixed on the top of the slide, and the pressing block is T-shaped. The pressing block is clamped in four adjacent positioning blocks in the two rows.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the present invention, the large end of the ejector pin rests against the baffle to position the ejector pin head. The first V-shaped groove is used to accommodate the head rod section of the ejector pin, and the second V-shaped groove is used to accommodate the middle rod end of the ejector pin. After the ejector pin is placed, the pressing block is pressed against the ejector pin and fixed with the third screw. In this way, the ejector pin can be fixed in multiple positions as required. The slide can slide on the base, thereby adjusting the distance between the slide and the baffle.

[0013] 2. In the present invention, the limiting boss can prevent the slide from colliding with the baffle and affecting the clamping effect, and the guide bar is slidably installed in the slide groove to guide the movement of the slide. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-6An adjustable ejector processing jig includes a base 1 and an ejector 10. The base 1 is U-shaped. A baffle 3 for limiting one end of the ejector 10 is fixed to one end of the base 1 by a first screw 2. A slide 6 is slidably mounted on the base 1. A first V-shaped groove 13 and a second V-shaped groove 14 are provided on the top of the slide 6 for placing the ejector 10. A pressure block 8 for pressing the ejector 10 is fixed to the slide 6 by a third screw 7. A baffle 3 is fixed on the side of the slide 6 close to the baffle 3 to prevent the slide 6 from interfering with the baffle 3. The collision limit boss 11, the guide bars 5 are fixed on both sides of the base 1 by the second screws 4, the slide 6 is provided with a slide groove 12 on both sides, the guide bar 5 is slidably installed in the slide groove 12, the first V-shaped groove 13 and the second V-shaped groove 14 are equidistantly arranged, and two first V-shaped grooves 13 and two second V-shaped grooves 14 are provided between adjacent positioning blocks 9 in any row, and two rows of equidistantly arranged positioning blocks 9 are fixed on the top of the slide 6, the pressure block 8 is T-shaped, and the pressure block 8 is clamped in the four adjacent positioning blocks 9 in two rows.

[0023] Working principle: When in use, the large end of the ejector pin 10 rests on the baffle 3 to position the head of the ejector pin 10. The first V-shaped groove 13 is used to place the head rod section of the ejector pin 10, and the second V-shaped groove 14 is used to place the middle rod end of the ejector pin 10. After the ejector pin 10 is placed, it is pressed against the ejector pin 10 by the pressure block 8 and fixed by the third screw 7. In this way, the ejector pin 10 can be fixed in multiple positions as required. The slide 6 can slide on the base 1, so that the distance between the slide 6 and the baffle 3 can be adjusted. The limiting boss 11 can prevent the slide 6 from colliding with the baffle 3 and affecting the clamping effect. The guide bar 5 is slidably installed in the slide groove 12 to guide the movement of the slide 6.
