Description

Mold capable of freely adjusting positioning size of product

Technical Field

The utility model relates to a technical field of moulding plastics, more specifically relates to a can freely adjust mould of product location size.

Background

At present, the automobile industry is rapidly developed, the requirements on the product quality are continuously improved, and the period for developing the product is required to be shortened as much as possible. However, problems of undesirable product dimensions often occur during injection molding.

At present, the traditional mould usually adopts modes such as welding, deferrization, discharge, change mold insert to repair the mould, and the change that realizes the product only has two kinds of modes: reducing the glue of the product (adding iron into the mould) and adding the glue of the product (removing iron from the mould). Because the positioning structures of the traditional die are integrally formed on the side of the female die or the male die, if one positioning structure has the problem of size out of tolerance, the die needs to be repaired on the side of the whole female die or the male die. That is to say, in the two modes, the movable die and the fixed die of the die are detached, the position to be changed is moved to the machine station for processing, after the processing is completed, the changed die is assembled with the die, whether the changed product size meets the requirement is determined, and if the changed product size does not meet the requirement, the die is disassembled, processed, assembled and determined again until the product size meets the requirement. The product development cycle is longer and the service life of the mold is shortened by changing and confirming for many times. Moreover, multiple machining also causes adverse effects: firstly, the time of welding or machining of the numerical control milling machine is long, the development period of the product is further prolonged, and the development cost is increased; secondly, because the heat affected zone is larger during welding, the welded die may have the phenomena of collapse, deformation, undercut, cracking and the like, and the appearance and the size of the product are affected, so that the product needs to be changed again.

Detailed Description

The following description of the preferred embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a but mould of free adjustment product location size of a preferred embodiment, including die frame 1, die frame 1 has die cavity 2 to the indent, is equipped with a plurality of detachable location inserts 3 in the die cavity 2.

As shown in fig. 2-4, the positioning insert 3 comprises an insert body 31 and two positioning structures 32 detachably connected to the insert body 31. The insert body 31 has two positioning through holes 311, and the two positioning structures 32 are respectively mounted above the two positioning through holes 311 by the first fastening member 33. The insert body 31 is further provided with two mounting holes 312, and the second fastening member 34 passes through the mounting holes 312 to fix the insert body 31 in the cavity 2. It should be noted that the shape and size of the insert body 31 are made according to the shape and size of the product to be molded.

Each positioning structure 32 corresponds to one positioning surface of the product to be molded, and includes a first insert 321 and a second insert 322 coaxially aligned, with the second insert 322 located between the first insert 321 and the positioning through-hole 311. The first inserts 321 are formed according to the positioning surface of the product to be molded, and the first inserts 321 in each positioning structure 32 may have the same or different structures. The second insert 322 is composed of at least one spacer, and the thickness of the spacer can be set according to actual needs for adjusting the positioning dimension of the product. The number of shims in the second insert 322 of each locating structure 32 may be varied to achieve independent adjustment of each locating structure 32 and thus each locating surface of the product.

The first fastener 33 includes a pin 331 which passes through the locating through hole 311 and the second insert 322 from below the insert body 31 to be removably attached to the first insert 321, and a screw 332 which passes through the locating through hole 311 from below the insert body 31 to be removably attached to the second insert 322. It should be noted that the screw 332 may also be replaced by other fastening members, such as a pin, which is not limited by the present invention.

Likewise, the second fastener 34 may be a screw, pin, or other standard fastener.

The utility model discloses a use of mould roughly as follows:

the second insert 322 including a shim is first fixed above the positioning through hole 311 of the insert body 31 by the screw 332, the first insert 321 is then fixed above the second insert 322 by the insert pin 331, the insert body 31 with the first insert 321 and the second insert 322 mounted thereon is then placed in the cavity 2, and the second fastener 34 is screwed or inserted into the mounting hole 312. Thus, the positioning insert 3 is completely installed. And (4) closing the installed female die and the corresponding male die, mounting the female die and the corresponding male die on an injection molding machine, and determining whether the size of the product is within the tolerance range on the injection molding machine. If not, the female die and the male die are opened, and the second fastening piece 34 of the positioning insert 3 to be adjusted is unscrewed, so that the positioning insert 3 is detached from the female die. At the same time, the insert pin 331 and the screw 332 in the positioning insert 3 are unscrewed, and a shim is added to the second insert 322 to adjust the height of the positioning structure 32. And after the adjustment is finished, closing the die again for confirmation until the size of the product meets the requirement.
