Referring to FIG. 1 and FIG. 2 , a clamp mold base 100 according to a preferred embodiment of the present invention includes a first mold base 10 , a pull rod 20 , a second mold base 30 and four guide posts 40 . .

The first die holder 10 has a top surface 11 , a coupling hole 12 , and four corner posts 13 and at least two clamping blocks 14 protruding upward from the top surface 11 . The coupling hole 12 is formed by being recessed from the top surface 11 to provide a combination of the rods 20; in the embodiment, the clamping block 14 and the corner post 13 are integrally formed with the first mold base 10, wherein the corner posts 13 are respectively located at the top. At the four ends of the face 11, and the height of the corner post 13 is higher than the height of the clamp block 14; the number of the clamp blocks 14 is eight in this embodiment, respectively, in two groups, and is disposed on two adjacent corner posts. Between 13 and close to the circumference of the first mold base 10, for convenience of explanation, two of the clamps 14 will be described below.

Each of the clamping blocks 14 has a width W in the horizontal direction. A clamping groove 15 is formed between the two clamping blocks 14. The insertion groove 15 has an appearance of being wide and narrow, and has a groove bottom 151 and two groove walls 152. Each of the groove walls 152 has a vertical section 152a, an inclined section 152b and an extension section 152c. One end of the vertical section 152a is connected to the groove bottom 151, and the other end of the vertical section 152a is connected to the inclined section 152b. The extension section 152c connects the inclination. Section 152b; each inclined section 152b and the extension section 152c are inclined flat faces. The vertical distance between the groove bottom 151 and the top edge of each of the clamping blocks 14 is a groove depth D, and a first angle θ1 is interposed between the inclined portion 152b and the extending direction of the vertical segment 152a, and the extending portion 152c is The extending direction of the vertical segment 152a is set to a second angle θ2, and the second angle θ2 is greater than the first angle θ1, so that the groove width of the recess 15 is upwardly divergent; wherein the groove depth D, the groove The width W and the first angle θ1 satisfy the following conditions: (1) 1.5 mm ≦ W ≦ 4 mm; (2) 4 mm ≦ D ≦ 8 mm; (3) 4 ° ≦ θ 1 ≦ 9 °; (4) 1 ≦ D / W ≦ 5.33.

On the other hand, when the first angle θ1 is excessively large, the inclined section 152b of the recessed groove 15 can disperse the external force into other component forces to prevent the occurrence of cracking when the external force is applied. However, the guide post 40 and the recessed groove 15 There is also a gap between them, and it is impossible to maintain a good positioning, which may cause the sloshing to occur. Moreover, when the groove depth of the recessed groove 15 is too shallow and the width of the clamp block 14 is narrow, the structural strength of the clamp block 14 is insufficient and the engagement groove 15 has a weak binding force to the guide post 40, and once subjected to an external force, This can cause the guide post 40 to loosen or the collapse of the clamp 14 to occur.

Accordingly, when the first angle θ1, the groove depth D of the groove 15 and the width W of the clamp 14 satisfy the above conditions, that is, 1.5 mm ≦ W ≦ 4 mm; 4 mm ≦ D ≦ 8 mm; 4 ° ≦ θ 1 ≦ 9 °; 875 ≦ D / W ≦ 1; the guide post 40 and the groove 15 can improve the structural strength, and a good fit between the two, so that the first mold base 10 and the second after the combination Good stability is achieved between the mold bases 30 to extend the service life.
