Description

Technical Field

[0001] The utility model relates to the technical field of insert pin installation structures, and particularly relates to an insert pin fixing structure for a compact inclined sliding block. Background Technique

[0002] When the diameter of the BOSS post of an injection molded product is relatively small, such as only about 1 mm, it is necessary to make exhaust through holes for it. Otherwise, problems such as air entrapment, burning, and lack of glue will occur during injection molding.

[0003] The patent document with the patent announcement number: CN218928478U discloses a mold insert pin ejection mechanism. The scheme includes an oil cylinder, a connecting rod, a sliding block, a fixed block, and an ejector rod. The connecting rod is arranged at the output end of the oil cylinder, the sliding block is arranged at the free end of the connecting rod. An inclined sliding groove with an inclined angle is opened on the sliding block along the length direction of the connecting rod. The cross-section of the sliding groove is convex. One end of the fixed block is installed in the mold core, and the other end is slidably arranged in the sliding groove, so that when the connecting rod extends, it drives the fixed block to extend perpendicular to the moving direction of the sliding block. One end of the ejector rod is arranged in the fixed block. The structure of this application is simple and practical, and reasonably utilizes the structure of the mold itself, and can effectively eject the insert pin in the inner hole of the molded part.

[0004] The above scheme ejects the insert pin from the product. For the relatively small BOSS post on the product, generally, an insert pin needs to be inserted from the outside for exhaust. Currently, when installing an insert pin on a relatively small inclined sliding block, only an insert pin hole can be cut in the middle along the length direction of the inclined sliding block, and then the hanging platform of the insert pin is placed on the T-slot of the inclined sliding block. Since there are generally moving parts at the T-slot, there is a risk that the moving part slides on the hanging platform surface of the insert pin, causing the insert pin to protrude above the T-slot surface. Once it protrudes, it will cause the moving part to hit the insert pin, resulting in losses. Content of the Utility Model

[0005] In order to overcome the above technical problems, the purpose of the utility model is to provide an insert pin fixing structure for a compact inclined sliding block, which solves the problem that there is no good installation structure for fixing an insert pin with an extremely small size on an inclined sliding block, and there is a risk of pin collision.

[0006] The purpose of the utility model can be realized by the following technical solutions:

[0007] An insert pin fixing structure for a compact inclined sliding block includes an inclined sliding block, a stop block, and an insert pin. The inclined sliding block is provided with an installation through groove, the installation through groove is detachably connected to the stop block, and the insert pin is inserted and fixed in the cavity formed therebetween;

[0008] The insert pin includes a fixed block and a needle head. The fixed block is limited and fixed in the cavity formed by the installation through groove and the stop block, and the needle head extends along the axial direction of the inclined sliding block and penetrates through the end of the inclined sliding block;

[0009] The fixing structure further includes a connecting member for locking and limiting the inclined sliding block, the stop block, and the insert pin.

[0010] Furthermore, at both ends of the installation through groove, a first limiting groove and a second limiting groove are respectively formed, and at both ends of the stop block, connecting protrusions are formed corresponding to the first limiting groove and the second limiting groove.

[0011] Furthermore, a sliding groove is formed through the inclined sliding block corresponding to the position of the needle head.

[0012] Furthermore, the fixing block is connected with at least two needle heads, and curved surface protrusions are formed by extending upward on the top surfaces on both sides of the fixing block, and a slot is formed on the stop block corresponding to the curved surface protrusion.

[0013] Furthermore, a plurality of diversion grooves are formed on the surfaces of the inclined sliding block and the stop block.

[0014] Furthermore, the connecting member is a screw, and the screw sequentially penetrates through the stop block and the fixing block from the outside to the inside along the radial direction of the inclined sliding block, and the end of the screw is threadedly connected with the inclined sliding block.

[0027] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0028] Such as Figure 1 、 Figure 2 shown, a fixing structure for an insert pin of a compact inclined sliding block includes an inclined sliding block 2, a stop block 3 and an insert pin 4. This fixing structure is used to install the insert pin 4. After the insert pin 4 is installed in place, the inclined sliding block 2 drives the insert pin 4 to move to perform jacking exhaust on the BOSS post 11 on the surface of the product 1; An installation through groove 21 is formed through the inclined sliding block 2, and the installation through groove 21 is detachably connected to the stop block 3, and the insert pin 4 is inserted and fixed in the cavity formed therebetween; Such as Figure 5 、 Figure 6 、 Figure 7 shown, the insert pin 4 includes a fixed block 41 and a needle tip 42. The fixed block 41 is limited and fixed in the cavity formed by the installation through groove 21 and the stop block 3, and the needle tip 42 extends along the axial direction of the inclined sliding block 2 and penetrates the end of the inclined sliding block 2. A slide groove 24 is formed through the inclined sliding block 2 corresponding to the position of the needle tip 42; This fixing structure also includes a connecting piece 6, and the connecting piece 6 is used to limit and lock the inclined sliding block 2, the stop block 3 and the insert pin 4.

[0029] When installing the insert pin 4, first insert the needle tip 42 of the insert pin 4 along the sliding groove 24 until it is completely inserted. Then, the fixing block 41 will abut against one end of the installation through groove 21. Finally, the stopper 3 can be embedded into the installation through groove 21, and the three are locked using the connecting member 6. In this solution, the insert pin 4 is made shorter, and a stopper 3 is detachably connected to the middle part of the inclined sliding block 2. The insert pin 4 is clamped and fixed between the stopper 3 and the inclined sliding block 2. The stopper 3 adopts a limiting and fixing method, which well solves the fixing problem of the insert pin 4, there is no problem of the insert pin 4 hitting the needle with the moving part, and it is convenient for processing. When there is a problem, the insert pin 4 can also be quickly replaced.

[0030] As shown in Figure 5 , Figure 6 , Figure 8 As shown, limiting grooves one 22 and limiting grooves two 23 are respectively formed at both ends of the installation through groove 21. Connecting convex blocks 31 are formed at both ends of the stopper 3 corresponding to the limiting grooves one 22 and limiting grooves two 23. The two connecting convex blocks 31 are respectively clamped and fixed with the limiting grooves one 22 and limiting grooves two 23, thereby firmly fixing the insert pin 4.

[0031] As an example, as shown in Figure 7 , the fixing block 41 is connected with at least two needle tips 42. The top surfaces on both sides of the fixing block 41 extend upward to form curved protrusions. A slot is formed on the stopper 3 corresponding to the curved protrusions. The combination of the curved protrusions and the stopper 3 prevents the insert pin 4 from shaking during use.

[0032] As an example, as shown in Figure 3 , Figure 4 As shown, a plurality of diversion grooves 5 are provided on the surfaces of the inclined sliding block 2 and the stopper 3. The diversion grooves 5 are circular grooves. The diversion grooves 5 can guide the flow of fluid, such as coolant or lubricating oil, to ensure a stable temperature and lubrication state during the working process of the mold. Moreover, the diversion grooves 5 help to improve the heat dissipation capacity, promote the uniform distribution of heat inside and outside the mold, prevent local overheating, thereby reducing the risk of deformation and ensuring the quality of the formed product 1; by providing the flow of lubricant or coolant, it can indeed reduce the friction between the inclined sliding block 2 and other components and improve the smoothness and efficiency of the inclined sliding block 2.

[0033] Further optimizing the above technical solution, as shown in Figure 4 , the connecting member 6 is a screw. The screw sequentially penetrates the stopper 3 and the fixing block 41 from the outside to the inside along the radial direction of the inclined sliding block 2. The end of the screw is threadedly connected to the inclined sliding block 2. After the stopper 3 and the insert pin 4 are both installed in place, the stopper 3, the insert pin 4, and the inclined sliding block 2 are locked through the connecting member 6.
