Abstract

The utility model discloses an inner mold core device for manufacturing a polyvinyl chloride (PVC) thermal shrinkage printed film. The inner mold core device comprises a device body, wherein a mold core is arranged on the device body; a current divider is also arranged on the device body; a through pipe with an outer thread is also arranged inside the mold core; a nut is arranged at the top end of the through pipe. Compared with the prior art, the current divider of the mold core is relatively convenient to dismantle; a product is good in thickness uniformity; the joint of the current divider and the mold core is good in fastening tightness; the phenomenon of material flow is not generated; the fitting accuracy is not affected after the mold is dismantled and cleaned for a plurality of times. Thus, the target of the inner mold core device is achieved.

Description

Manufacture the inner mould core device of PVC heat shrinkable printed film

Technical field

The utility model relates to a kind of inner mould core modifying device, particularly a kind of inner mould core device of manufacturing PVC heat shrinkable printed film.

Background technology

In the manufacturing process of PVC heat shrinkable printed film, PVC powder becomes plastic melt to be sent to inner mould core through extruder thermal conversion, by inner mould core, plastic melt is heated and expands, and then once propels the price of.

As shown in Figure 1, in PVC heat shrinkable printed film manufacture process, employing equipment is divided into host machine part and subsidiary engine part, and wherein, host machine part comprises: extruder 1 and the mould of included screw rod; Mould comprises: drainage plate 2, current divider 3, core rod 4 and die sleeve 5 etc.; Subsidiary engine partly comprises: front haulage and herringbone clamping plate 6, heating water tank and draw 7, rear haulage and herringbone clamping plate 8, linearity control device 9, bellows and screw feeding machine.

As shown in Figure 2, the heating of the plastic melt that inner mould core is mainly used in being sent by extruder, shunting and expansion, in above-mentioned existing mechanism, core rod 120 easily ruptures with current divider 110 junctions, and dismounting is inconvenient, and junction fit sealing is bad.

Therefore, need especially a kind of inner mould core device of the PVC of manufacture heat shrinkable printed film, to solve prior art deficiency, the quality of improving product and yield rate.

Utility model content

The problems such as the purpose of this utility model is to provide a kind of inner mould core device of the PVC of manufacture heat shrinkable printed film, and inner mould core service life and sealing are unstable, disassembly, cleaning are difficult to solve, and production product became uneven is even.

The technical problem that the utility model solves can realize by the following technical solutions:

An inner mould core device for PVC heat shrinkable printed film, is characterized in that, it comprises device body, on described device body, is provided with core rod, is also provided with current divider on described device body; In described core rod, be also provided with externally threaded siphunculus, the top of described siphunculus is provided with nut.

In an embodiment of the present utility model, between described nut and core rod, be also provided with packing ring.

The inner mould core device of manufacture PVC heat shrinkable printed film of the present utility model, compared with prior art, the dismounting of core rod current divider is more convenient, the product thickness uniformity is better, and current divider and core rod junction fit sealing are good, can not produce stream material phenomenon, repeatedly pulling down can be not influenced with cleaning die quality of fit.

Feature of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.

Accompanying drawing explanation

Fig. 1 is the structural representation of manufacturing PVC heat shrinkable printed film equipment in prior art;

Fig. 2 is the structural representation of inner mould core of the prior art;

Fig. 3 is the structural representation of the inner mould core device of manufacture PVC heat shrinkable printed film of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 3, a kind of inner mould core device of manufacturing PVC heat shrinkable printed film, it is characterized in that, it comprises device body 10, on described device body 10, is provided with core rod 20, on described device body, be also provided with current divider 30, in described core rod, be also provided with externally threaded siphunculus 40, the top of described siphunculus 40 is provided with nut 50, and the dismounting of core rod current divider is more convenient, the product thickness uniformity is better, and repeatedly pulling down can be not influenced with cleaning die quality of fit.

In an embodiment of the present utility model, between described nut 50 and core rod 20, be also provided with packing ring 60, make the sealing property of inner mould core device better, can not produce stream material phenomenon.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
