Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0017] It can be seen from Figure 2 that the present invention includes: a common mold base 10, an interchangeable mold core 20; the interchangeable mold core 20 is detachably connected to the common mold base 10; the interchangeable mold core 20 may be One or more; the interchangeable mold core 20 includes a mold core frame 201 matched with the common mold frame 10 and a convertible insert 202 in the mold core frame 201;

[0018] It can be seen from FIGS. 3A and 3B that the one interchangeable mold core is an O-shaped mold base clamped from the front; the mold core base 201 is diagonally connected to the common mold base 10 through the diagonal wedge 101;

[0019] It can be seen from Figures 4A and 4B that the two interchangeable mold cores are H-shaped mold bases clamped from the side; the mold core base 201 is positioned and connected to the common...

Abstract

The present invention relates to a composite-typed mould, comprising a public mould base (10) and an interchangeable mould core (20); the interchangeable mould core (20) is detachably connected with the public mould base (10); the number of the interchangeable mould core (20) is capable of only one or more; the interchangeable mould core (20) comprises a mould core holder (201) which is matched with the public mould base (10) and a transferable mold insert (202) which is arranged in the mould core holder (201). The present invention has the advantages that the manufacturing cycle can be shortened by about 25 percent; the cost of the module can be reduced by 5 percent to 10 percent; and the transition and the maintenance of the mould in the process of injection molding are more convenient and quicker.

Description

Technical field [0001] The invention relates to a mold, in particular to the structure between a mold base and a mold core in the mold. Background technique [0002] In the mold design, manufacturing and injection molding of communication and automobile connectors, because the product features are mostly serialized, the structure is similar, the size is small, the precision is high, and the update is fast, so the requirements for mold design must be developed quickly, stable production, and Easy to maintain. [0003] It can be seen from Fig. 1 that the mold base 1 and the mold core 2 in the prior art mold have a one-to-one correspondence, that is, a pair of molds can only produce one product; and the mold base and the mold core fit are clearance fits. The so-called clearance fit means that there is generally a gap of 0.01~0.02mm between the mold base and the mold core, which may cause a slight misalignment of the front and rear mold cores, which affects the dimensional accuracy. ...
