Description

Technical Field

[0001] The utility model relates to the technical field of ejector pin mechanisms, and more specifically, to an ultrasonic ejector pin mechanism for a diamond mould. Background Art

[0002] A diamond mold is a mold made of artificial diamond material and is used to manufacture high-precision and high-wear-resistant parts or products. During the processing of the diamond mold, an ultrasonic ejector is required to polish the edges and corners of the mold entrance in the center of the diamond mold using ultrasonic waves and the tapered end of the ejector.

[0003] In the prior art, when the ultrasonic ejector mechanism is in use, the steel needle needs to be welded to the fixed seat by copper welding. After long-term use, the end of the ejector will be worn. At this time, the staff needs to remove the ejector welded to the fixed seat, grind it, and then re-weld it.

[0004] However, installing the ejector pin by manual welding can easily cause the conical end of the ejector pin to deviate from the center of the mold, thereby causing the ejector pin to bend and affecting its service life. Therefore, a diamond mold ultrasonic ejector pin mechanism is proposed to improve the existing problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide an ultrasonic ejector mechanism for a diamond mold.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultrasonic ejector mechanism for a diamond mold, comprising an ejector body, wherein the ejector body comprises a fixing rod, a mounting rod arranged at one end of the fixing rod, and an ejector arranged at an end of the mounting rod away from the fixing rod; wherein the fixing rod and the mounting rod are both conical, an end of the fixing rod with a small diameter can be connected to an end of the mounting rod with a large diameter, a fixing hole is provided at an end of the fixing rod close to the mounting rod, a latch is provided at an end of the mounting rod away from the ejector, and the latch can be plugged into the fixing hole; an end of the ejector close to the mounting rod can penetrate to an end of the latch away from the mounting rod and extend into the fixing hole.

[0007] The utility model is further configured as follows: grooves are symmetrically provided on the side wall of the fixing rod away from the mounting rod, and a threaded groove is also provided on one end of the fixing rod away from the mounting rod.

[0008] The utility model is further configured as follows: a limiting hole is further provided on the inner wall of the fixing hole away from the mounting rod, and the fixing hole can be communicated with the limiting hole.

[0009] The utility model is further configured as follows: a limit pin is further provided at one end of the latch pin away from the mounting rod, and the limit pin can be inserted in the limit hole in cooperation.

[0010] The utility model is further configured as follows: a side wall of the installation rod close to the latch is symmetrically provided with placement grooves.

[0011] The utility model is further configured as follows: one end of the ejector pin is provided with a conical surface, and the other end is provided with a cylindrical surface, and the end of the ejector pin away from the conical surface can penetrate to the end of the limit pin away from the plug pin and extend into the limit hole.

[0012] By adopting the above technical solution, the limit pin is squeezed by one end of the cylindrical surface of the ejector pin, causing the side wall of the limit pin to expand, thereby causing an interference fit between the cylindrical surface of the ejector pin, the limit pin and the limit hole, thereby further improving the firmness of the fixing rod, the mounting rod and the ejector pin.

[0013] In summary, the present application includes at least one of the following beneficial technical effects:

[0014] (1) The fixing hole is located on the central axis of the fixing rod, and the end of the ejector pin close to the mounting rod can penetrate to the end of the pin away from the mounting rod and extend into the fixing hole. Therefore, when the fixing rod and the mounting rod are plugged and fixed through the pin and the fixing hole, the situation in which the conical surface of the ejector pin and the center of the mold are offset by manual welding is avoided, thereby achieving precise alignment of the ejector pin and the center of the mold, thereby increasing the service life of the ejector pin.

[0015] (2) The end of the ejector pin away from the conical surface can penetrate to the end of the limit pin away from the plug pin and extend into the limit hole. Therefore, in the process of extending into the limit hole, the end of the ejector pin located on the cylindrical surface will squeeze the limit pin, causing the side wall of the limit pin to expand, thereby causing the cylindrical surface of the ejector pin, the limit pin and the limit hole to have an interference fit, thereby further improving the firmness of the fixing rod, the mounting rod and the ejector pin.

DETAILED DESCRIPTION

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0022] See also Figure 1-Figure 3 , the utility model provides the following technical solutions:

[0023] Example 1, see Figure 1-Figure 3 A diamond mold ultrasonic ejector mechanism comprises an ejector body 1, the ejector body 1 comprises a fixing rod 11, a mounting rod 12 arranged at one end of the fixing rod 11, and an ejector pin 13 arranged at an end of the mounting rod 12 away from the fixing rod 11; the fixing rod 11 and the mounting rod 12 are both tapered, the end of the fixing rod 11 with a small diameter can be connected to the end of the mounting rod 12 with a large diameter, a fixing hole 111 is provided at the end of the fixing rod 11 close to the mounting rod 12, a latch 121 is provided at the end of the mounting rod 12 away from the ejector pin 13, and the latch 121 can be plugged into the fixing hole 111; the end of the ejector pin 13 close to the mounting rod 12 can penetrate to the end of the latch 121 away from the mounting rod 12 and extend into the fixing hole 111.

[0024] When assembling the fixing rod 11 and the mounting rod 12, since both the fixing rod 11 and the mounting rod 12 are tapered, in order to ensure the stable connectivity between the fixing rod 11 and the mounting rod 12, it is necessary to align the small diameter end of the fixing rod 11 with the large diameter end of the mounting rod 12, and then by plugging the pin 121 into the fixing hole 111, the purpose of preliminarily fixing the fixing rod 11 and the mounting rod 12 is achieved, thereby improving the stable connectivity.

[0025] And because the fixing hole 111 is located on the central axis of the fixing rod 11, the end of the ejector pin 13 close to the mounting rod 12 can penetrate to the end of the latch 121 away from the mounting rod 12 and extend into the fixing hole 111. Therefore, when the fixing rod 11 and the mounting rod 12 are plugged and fixed to the fixing hole 111 through the latch 121, the situation in which the conical surface 131 of the ejector pin 13 and the center of the mold are offset due to manual welding is avoided, thereby achieving precise alignment of the ejector pin 13 with the center of the mold, thereby increasing the service life of the ejector pin 13.

[0026] See also Figure 1-Figure 3 Furthermore, grooves 112 are symmetrically provided on the side wall of the fixing rod 11 away from the mounting rod 12 , and a threaded groove 113 is also provided on one end of the fixing rod 11 away from the mounting rod 12 .

[0027] The function of the groove 112 is to facilitate the staff to hold the fixing rod 11 with their fingers, thereby avoiding the phenomenon of slipping due to sweating of the hands when the fixing rod 11 is twisted during installation with other mechanisms, thereby improving practicality.

[0028] The function of the thread groove 113 is to rotate the fixing rod 11 so that the fixing rod 11 is threadedly fixedly connected with other mechanisms through the thread groove 113, thereby improving the connection stability of the fixing rod 11 and other mechanisms.

[0029] When it is necessary to explain, other mechanisms refer to components that can be connected to the fixing rod 11 through the threaded groove 113 .

[0030] See also Figure 1-Figure 3 Furthermore, a limiting hole 114 is provided on the inner wall of the fixing hole 111 away from the mounting rod 12, and the fixing hole 111 can be connected to the limiting hole 114; a limiting pin 122 is also provided on the end of the latch 121 away from the mounting rod 12, and the limiting pin 122 can be inserted in the limiting hole 114.

[0031] Among them, during the installation process of the fixing rod 11 and the installation rod 12, since a limiting hole 114 is also provided on the inner wall of the fixing hole 111 away from the installation rod 12, a limiting pin 122 is also provided on the end of the latch 121 away from the installation rod 12. The limiting pin 122 can be inserted in the limiting hole 114, so the limiting pin 122 will also be inserted in the limiting hole 114, thereby achieving the purpose of secondary fixing of the fixing rod 11 and the installation rod 12, thereby improving the stable connectivity.

[0032] See also Figure 1-Figure 3 Furthermore, a placement groove 123 is symmetrically provided on the side wall of the mounting rod 12 near the latch 121 .

[0033] The design of the placement groove 123 makes it convenient for the staff to pinch the installation rod 12 so that the installation rod 12 and the fixing rod 11 can be plugged in.

[0034] See also Figure 1-Figure 3 Furthermore, one end of the ejector pin 13 is provided with a conical surface 131 and the other end is provided with a cylindrical surface 132 . The end of the ejector pin 13 away from the conical surface 131 can penetrate to the end of the limiting pin 122 away from the plug pin 121 and extend into the limiting hole 114 .

[0035] Among them, since the end of the ejector pin 13 away from the conical surface 131 can penetrate to the end of the limiting pin 122 away from the plug pin 121 and extend into the limiting hole 114, during the process of extending into the limiting hole 114, the end of the ejector pin 13 located on the cylindrical surface 132 will squeeze the limiting pin 122, causing the side wall of the limiting pin 122 to expand, thereby causing the cylindrical surface 132 of the ejector pin 13, the limiting pin 122 and the limiting hole 114 to have an interference fit, thereby further improving the firmness of the fixing rod 11, the mounting rod 12 and the ejector pin 13.

[0036] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
