Description

A kind of mould structure that the fast quick change chamber core of not demoulding can be achieved

Technical field

The present invention relates to injection molding machine technical field more particularly to a kind of mold knots that the fast quick change chamber core of not demoulding can be achieved Structure.

Background technique

General mould structure is by the structure shape of formed product component design forming core (chamber) and dynamic (quiet) template mosaic Formula designs embedding piece groove in dynamic (quiet) template, and type core (chamber) is fixed in dynamic (quiet) template by way of screw is locked at the back side, In product design, part series of products structure is similar, usually using with set mould bases, is carried out by the interchangeable form of type core (chamber) more The injection molding of product product is covered, in this way after the completion of a set of product is molded, prototype core (chamber) is split out, New-core is changed to (chamber) carries out injection molding and obtains new product, when mould structure improves, is also designed as type core (chamber) front lock screw and fixes Form remodel core (chamber) more from front convenient for not form removal to improve replacement efficiency；

The above replacement form, is both needed to remove from injection molding machine from by mold, and correlate template is dismantled taking-up type core (chamber) more It is retightened again after changing New-core (chamber), upper machine is fixed again, during replacement, not only needs a large amount of time demolition, installation, more Change, the time is longer occupy it is artificial more, meanwhile, injection molding machine limitation uses when replacement, and board utilization rate is substantially reduced, consumed Great amount of cost, and production efficiency is lower；

In the prior art, design mode core (chamber) slot in dynamic (quiet) template, type core (chamber) is fixed in dynamic (quiet) template, and Type core (chamber) back side is fixed by screws in dynamic (quiet) template, when if necessary to design changeable core (chamber), in mould structure The structure type that may be designed as front lock screw in the case where permission, after the completion of mold injection, by mold from injection molding machine It removes, dynamic (quiet) mould is dismantled respectively, and type core (chamber) is taken out, is then fixed by screws in the type core (chamber) needed replacing dynamic In (quiet) template, after the completion of replacement, then whole set of die is hung in injection molding machine and is fixed, carry out injection product；

The replacement of each type core (chamber) needs to remove mold from injection molding machine, fixing screws is then removed, by prototype core It takes out, replace New-core (chamber) and fixes in (chamber) driven (quiet) template, whole set of die is hung to injection molding machine again after completing installation It is fixed on platform, Injection moulded part is finally entered, replacement needs to expend the 8-12h time every time, it needs to take considerable time, meanwhile, During replacement, injection molding machine is in stop working state, seriously reduces utilization rate of equipment and installations, causes board and artificial waste.

Summary of the invention

The purpose of the present invention is to solve it is existing in the prior art replacement consuming time is long, aggravate hand labor The problems such as power, at high cost and reduction utilization rate of equipment and installations, and a kind of mould structure that the fast quick change chamber core of not demoulding can be achieved proposed.

To achieve the goals above, present invention employs following technical solutions:

A kind of mould structure that the fast quick change chamber core of not demoulding can be achieved, including dynamic model seat and quiet die holder are designed, the dynamic model seat Top is bolted with moving template, and the bottom end of the quiet die holder is bolted with disassembly mechanism.

Preferably, the disassembly mechanism includes the first pedestal, the second pedestal and changeable core group, and changeable core group is located at Between first pedestal and the second pedestal, the outer right wall of first pedestal offers the first changeable chamber group, and described first can The inner cavity for chamber group of remodeling is plugged with the first sliding block group, and the left side outer wall of second pedestal offers the second changeable chamber group, institute The inner cavity for stating the second changeable chamber group is plugged with the second sliding block group, and the first sliding block group and the second sliding block group with changeable core group It is integrally formed, the front and rear sides of first pedestal are bolted with the block to the limit of the first sliding block group, and block and first can Chamber group of remodeling position is corresponding.

Preferably, the block, the first changeable chamber group, the first sliding block group, changeable core group, the second sliding block group and second Changeable chamber group position corresponds, and central axis is in same horizontal line.

Preferably, first pedestal is spirally connected with the bottom end of the quiet die holder left and right sides respectively with the second pedestal.

Preferably, the changeable core group is clearance fit between the first pedestal and the second pedestal respectively, it is ensured that can The accurate molding for core group of remodeling.

Preferably, the front side length of second pedestal is greater than the front side length of the first pedestal, provides changeable core group and exists It is first to guiding role when replacement.

Proposed by the present invention, beneficial effect is:

1, the present invention passes through the cooperation of the first changeable chamber group and the second changeable chamber group, substitutes the structure of quiet template in original mould Effect reduces material and processing cost to reduce mould bases size；

2, block only removes operator's side block blocks by back-outing fixing screws in changeable core group, again when replacing completion It retightens in the first pedestal, without being replaced after removing mold from injection molding machine, shortens replacing construction, alleviate people Work labour；

3, demoulding is not needed when replacing changeable core group, operation can be fast implemented on injection molding machine, greatly improve production effect Rate.
