Description

Mould

Technical field

The present invention relates to a kind of mould, relate in particular to a kind of mould with temperature control structure.

Background technology

When utilizing mould to produce product, if desired die is carried out temperature control, traditional way is to heat up outside entire die or lower the temperature.

Yet, such control mode is too coarse, because the temperature control mode of this periphery is difficult to the temperature that accurate and effective is regulated mould inside, influence quality and the shaping efficiency of shaped article easily, especially when the complex-shaped of moulding product or the temperature that reaches when different structure is required were inequality, this temperature control mode was difficult to prove effective.

Summary of the invention

In view of this, be necessary to provide a kind of mould, this mould can the demand according to product be controlled mold temperature flexibly when shaped article.

A kind of mould, establish die in this mould, this mould also comprises a module, this module has opposite first and second surface, this die places between this first surface and this second surface, this module is provided with a plurality of first through holes and a plurality of second through hole, these a plurality of first through holes and this die are contiguous to be arranged, these a plurality of second through holes and this die are contiguous to be arranged, these a plurality of first through holes and these a plurality of second through holes intersect mutually and are interconnected, this module second surface is offered at least one first adjustment hole that is communicated with this first through hole, these a plurality of first through holes and these a plurality of second through holes are used for transport liquid, by controlling this first adjustment hole to regulate the flow direction of liquid.

Compared with prior art, mould provided by the invention can be selected one or more through holes and import liquid adjusting die temperature in through hole according to structure and the temperature requirements of die, and, the through hole of mould provided by the invention also has adjustment hole, by opening adjustment hole or closing the trend that adjustment hole changes liquid in the through hole, increased the type of flow of liquid, be applicable to the temperature demand for control of the shaped article of multiple structure, save the time of redesign die or through hole trend, reduced production cost.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail.

See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the mould 30 that first embodiment of the invention provides comprises die 31, module 32, and the overall structure of module 32 is rectangular structure, and it has opposite first 321 and second surface 322.Wherein, receiving space 120 is caved in, formed in the subregion of first surface 321 between first surface 321 and second surface 322, and receiving space 120 is used for accommodating die 31.The shape of receiving space 120 is decided according to the external shape of die 31.

Contiguous this receiving space 120 is provided with a plurality of first through holes 41 in this module 32.These a plurality of first through holes 41 run through two relative sides 123 and the side 124 of module 32.First through hole 41 is shorter to the distance of second surface 322 than the bottom surface 125 of receiving space 120 to the distance of second surface 322, makes the through hole 41 of winning can be arranged in module entity between bottom surface 125 and the second surface 322.

Be appreciated that first through hole 41 also can be the through hole of shaped form, it can arrange module 32 inner wriggling around receiving space 120.The number of first through hole 41 is not limited to shown in the present embodiment.

Preferably, these a plurality of first through hole 41 parallel equidistant arrangements.

It is different with the direction of first through hole 41 that the zone at contiguous die 32 places, the inside of module 32 is provided with two second through hole, 42, the second through holes 42, but all run through module 32.Second through hole 42 and first through hole 41 intersect and are interconnected.

Preferably, second through hole 42 and first through hole 41 intersect vertically and interconnect.

First through hole 41 and second through hole 42 are all for transport liquid, and liquid can be water or oil, by injecting the liquid of preference temperature to a plurality of first through holes 41 and selecting the injection of liquid and the purpose that outflow path reaches control die 31 temperature.

Mould 30 can further comprise the template 33 of accommodating module 32, the receiving space 333 that template 33 both sides have two side 330 and limited by two side 330.Receiving space 333 is used for accommodating module 42.

Further, sidewall 330 can arrange through hole 34 by corresponding second through hole 42, so that second through hole 42 is via through hole 34 and external communications.Be appreciated that according to the actual requirements through hole 34 can not established.

In order to increase the liquid communication route of mould 30, mould 30 is except being provided with first through hole 41 and second through hole 42, also can offer a plurality of second adjustment holes 43 that are communicated with this second through hole 42 in the position of second surface 322 corresponding second through holes 42 of module 32.

Second adjustment hole 43 is if blocked fully, and then the path at this adjustment hole place of blocking is obstructed; If second adjustment hole 43 is opened or do not blocked fully, then the path at its place is unobstructed, allows liquid to flow through.

Opening or closing of second adjustment hole 43 can be realized by multiple mode, is provided with screw thread such as the inwall at second adjustment hole 43, and bolt different in size is screwed in second adjustment hole 43, makes stay bolt be enough to block second adjustment hole 43, and short enough liquid flows through and gets final product.Also can in second adjustment hole 43, fill in stopper or with stopper pull out control second adjustment hole 43 state.

For example, the the 1st, 2,4,5 second adjustment hole 43 played on second through hole, 42 left sides of first row to be blocked up, the the 1st, 3,5 second adjustment hole 43 played on second through hole, 42 left sides of second row to be blocked up, the 2nd row to the one or both ends of first through hole 41 of the 5th row are played on a left side to be blocked up, then can realize the flow direction shown in arrow among the figure, reach the effect of the temperature of the optional position of freely controlling die.

See also Fig. 5, the module 52 that second embodiment of the invention provides is except a plurality of second adjustment holes 63 that are connected with second through hole 62 the setting of its second surface, and also its second surface is provided with a plurality of first adjustment holes 64 that are communicated with first through hole 61.The effect of first adjustment hole 64 and second adjustment hole 63 is identical with second adjustment hole 43 among first embodiment.

Some adjustment holes of closing are set as shown in the figure, open some adjustment holes and seal the first unnecessary through hole 61 and the port of second through hole 62, can realize the flow direction shown in arrow among the figure.It is very abundant that the inner flow passage of the module 52 that present embodiment provides moves towards mode, and the die to the manufacturing accurate device preferably carries out temperature control.

In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
