Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of molds, and in particular relates to an insert locking structure. Background Art
[0002] Inserts are irregular mold parts embedded in the mold to fix the template and fill the space between the templates. But at the same time, the inserts also need to be locked and fixed to ensure the accuracy of the mold.
[0003] Usually, threaded fixing is adopted for the embedded inserts, but the existing threaded fixing is mostly to match the threaded holes vertically drilled on the mold insert and the mold fixing plate, install threaded pins or threaded bolts in the holes, and fix the mold insert on the mold fixing plate by threaded fastening.
[0004] However, this fixing method requires a larger space structure. When the mold structure space is relatively tight and the insert is relatively small, it is difficult to use this method to achieve threaded fixing. Utility Model Content
[0005] Based on this, the utility model proposes an insert locking structure, which can lock thin and small inserts and is suitable for the needs of different molds.
[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a kind of insert locking structure, comprising: a mold core, an insert, a locking groove and a headless screw; the insert comprises a first insert and a second insert which are embedded in the left and right sides, the first insert and the second insert are respectively arranged vertically, the locking groove is arranged on the side of the first insert or the second insert, one end passes through the mold core, and the other end is connected to the insert close to it, and the angle between the axis of the locking groove and the side wall of the insert close to it is 20 to 45°; the inner side of the locking groove is provided with a thread, and the headless screw is arranged in the locking groove.
[0007] The structure realizes the fixation of thin and small inserts by arranging oblique locking grooves and cooperating with headless screws, which occupies less space and has a good fixing effect.
[0008] Preferably, the width of the first insert or the second insert is 5-10 mm.
[0009] Preferably, the height of the first insert or the second insert is H1, the height of the locking groove is H2, H2>1 / 2H1, and the locking effect is better.
[0010] Preferably, H1 is 15-20 mm.
[0011] Preferably, the total length of the locking groove is L, the length located in the first insert or the second insert is L1, L1≤0.2L, the length of the headless screw is l, l≥1 / 2L, and the locking effect is better.
[0012] Preferably, the radius of the locking groove is r, r=0.5H2~0.6H2.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The utility model realizes the fixation of thin and small inserts by setting an oblique locking groove and cooperating with a headless screw, which occupies less space and has a good fixing effect. Furthermore, by optimizing the size range, the fixing effect is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Example 1
[0021] refer to Figure 1-4 , a insert locking structure, comprising: a mold core 1, an insert 2, a locking groove 3 and a headless screw 4; the insert 2 comprises a first insert 21 and a second insert 22 which are engaged with each other on the left and right, the first insert 21 and the second insert 22 are respectively arranged vertically, the locking groove 3 is arranged on the side of the first insert 21, one end of which passes through the mold core 1, and the other end is connected to the first insert 21 close to it, and the angle between the axis of the locking groove 3 and the side wall of the insert close to it is 30°; a thread is arranged on the inner side of the locking groove 3, and the headless screw 4 is arranged in the locking groove 3. Since the locking groove 3 passes through the mold core 1 and is partially arranged in the first insert 21, and the first insert 21 and the second insert 22 are engaged with each other, the insert can be fixed by the headless screw 4, which occupies less space and has a good fixing effect.
[0022] The locking structure of the embodiment of the present invention is particularly suitable for thin and small inserts. The width W of the first insert or the second insert is 5-10 mm. For example, in the present embodiment, the width W of the first insert and the second insert are both 5 mm.
[0023] In addition, in order to achieve a better fastening effect, the height of the first insert or the second insert is set to H1, and the height of the locking groove is H2. H2 should be greater than 1 / 2H1. For example, in this embodiment, H2=2 / 3H1. In addition, the height of the insert is preferably 15-20mm. In this embodiment, the height is 15mm.
[0024] The total length of the locking groove 3 is set to L, the length located in the first insert 21 is L1, the length of the headless screw is l, L1≤0.2L, and the length l of the headless screw must be greater than or equal to half of the total length L of the locking groove. The locking effect is better and it is not easy to loosen.
[0025] The radius of the locking groove is r, and it is recommended that r be at least 0.5 to 0.6 of the locking groove height H2 for ease of processing.
[0026] The locking structure of the embodiment of the utility model realizes the fixing of thin and small inserts by setting an oblique locking groove and cooperating with a headless screw, which occupies less space and has a good fixing effect. Furthermore, by optimizing the size range, the fixing effect is further improved.
[0027] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
