Detailed Description
It is specifically noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, and the like in a specific posture, and if the specific posture is changed, the directional indicator is changed accordingly.
The technical solution of the present invention is further described below by way of examples:
[ example 1 ]
The utility model provides a tool that mould benevolence lathe work was used, it is shown with fig. 2 to combine, and the tool is well entire body, has: the fixture comprises an installation channel 1 and a positioning hole 2, wherein the installation channel 1 extends from the rear end to the front end of the fixture 1, and the positioning hole 2 is located at the front end of the fixture and is communicated with the installation channel 1. In the present embodiment, the positioning hole 2 has a supplement body 3 therein, and the front end surface of the supplement body 3 has an aspheric surface groove 31. Referring to fig. 3, the mold core has a positioning portion 101 and a molding portion 102, the molding portion 102 protrudes from the front surface of the positioning portion 101, and the front surface of the molding portion 102 has an aspheric recess 103. When the jig is used, the molding part 102 penetrates through the mounting channel 1 and is fixed in the positioning hole 2, and the aspheric surface groove 31 of the supplementing body 3 supplements the aspheric surface concave part 103 of the molding part 102 to form a complete circular cross section in combination.
Specifically, the jig further has: clamping groove 4, clamping groove 4 extends to the rear end from the front end of tool to clamping groove 4 and locating hole 2 intercommunication. The clamping groove 4 divides the jig into two parts, and when the mold core is installed, the two parts of the jig can be slightly broken off, so that the mold core can be conveniently inserted.
More specifically, the jig further has: the arc wall 5, the arc wall 5 is located the side of tool to the arc wall 5 communicates with clamping groove 4. The arc-shaped groove 5 can reduce the rigidity of materials, increase the resilience of the two parts of the jig, and enable the die core to be clamped more easily.
More specifically, the jig further has: the fixture comprises a locking hole 6 and a thread groove 7, wherein the locking hole 6 extends from the side surface of the fixture to the clamping groove 4, the thread groove 7 extends from the clamping groove 4 to the side surface of the fixture, and the locking hole 6 is opposite to the thread groove 7. During the use of the jig, a screw can pass through the locking hole 6 and is engaged with the thread groove 7, so that the mold core is clamped, and the stability of fixation is improved. More specifically, in the present embodiment, the locking holes 6 and the thread grooves 7 are both two, one of the locking holes 6 and one of the thread grooves 7 are both located above the positioning hole 2, and the other locking hole 6 and the other thread groove 7 are both located below the positioning hole 2.
Specifically, the jig is formed of a brass material. The brass has good plasticity, can bear cold and hot processing, has lower cost and can reduce the overall cost of the jig.
