The shell of electronic product is generally molded using mould heat pressure, needs to heat, be vented, cool down and push up when shell is molded The process such as go out, in this process due to mould heat pressure and product size the problem of, if radiating is not in time or radiating effect It is unreasonable, position deviation and the dislocation of the mutual cutting ferrule and screw hole of each outer casing member and then can be influenceed, is needed after the cooling period Ejection in time prevents the loss of other workpiece, and cooling procedure needs fast low temperature, ejection process be also required to suitable angle and Instrument, two kinds of functions can not be carried out simultaneously, then elongate the production cycle, and the high-volume that not being suitable for efficiency has strict demand is given birth to Production.

Utility model content

The purpose of this utility model is to provide a kind of hot pressing die inner chamber radiator structure, to solve in above-mentioned background technology Two kinds of functions of ejection and cooling of proposition can not be carried out simultaneously, then elongate the production cycle, and not being suitable for efficiency has strict want The production in enormous quantities problem asked.

To achieve the above object, the utility model provides following technical scheme：A kind of hot pressing die inner chamber radiator structure, bag Include stent, mould impression, outer frame, evacuation tube, hydraulic pressure button, bolt and left side heat emission hole, the stent it is interior Mobile mould is installed, the peripheral ring of the mould impression is around offering chilled water groove, and the inner laminating of freezing tank in the middle of side There are at least eight return pins, the inner side of the outer frame and mould impression are fixedly sleeved, and the outer radial direction of outer frame is opened Provided with least four stopper slots, upper and lower ends and the relief valve of the evacuation tube are interconnected, the inner of the hydraulic pressure button with Lift thimble to be flexibly connected, the relief valve is connected with mobile mould and stent by evacuation tube, and the bolt is fixed on Stent is fitted with the inside of the inner side of outer frame, the lifting thimble, the centre of the return pin is provided with relief valve, described Right side heat emission hole is provided with the right side of the heat emission hole of left side.

It is preferred that, the mobile mould includes module.

It is preferred that, the stopper slot is in " U " type structure.

It is preferred that, the relief valve, hydraulic pressure button, bolt and lifting thimble are all provided with four.

It is preferred that, the return pin number is eight, is divided into four groups of settings, every group of number is set to two.

Compared with prior art, the beneficial effects of the utility model are：The structure of the hot pressing die inner chamber radiator structure is set Meter is reasonable, compact, and after hot pressing, the shape of the brake pad of formed product eliminates radiating surface close to finished product or identical with finished product Grinding process, while saving the consumption of friction material, freezing tank utilizes the highly endothermic characteristic of water quality in itself, then through supercooling Go, reduce own temperature, can quickly cool by constantly circulation for mould, can reduce the hot-forming cycle, improve production effect Rate, relief valve is matched, greatly speeds up cool time.
