Abstract
The utility model discloses a cylinder protecting device for an injection molding machine. The cylinder protecting device comprises a protecting cover, wherein the protecting cover comprises an inner-layer protecting cover and an outer-layer protecting cover which is arranged on the exterior of the inner-layer protecting cover. According to the cylinder protecting device for the injection molding machine, the protecting cover is arranged as inner and outer two layers. After the cylinder protecting device is used for a long time and the outer-layer protecting cover starts to fall off, the inner-layer protecting cover still has a protecting function and molten materials are prevented from splashing and hurting an operator.
Description
Technical field
The utility model relates to a kind of injection machine machine barrel protector.
Background technology
Injection machine has another name called injection (mo(u)lding) machine or injector.It is to utilize mould for plastics to process the main former of the plastic products of different shape thermoplastic or thermosetting material.Be divided into vertical, horizontal, all electric.Injection moulding function heating of plastic applies high pressure to molten plastic, makes its ejaculation and is full of mold cavity.
The injection protection mechanism that existing injection machine generally adopts has two kinds basically: the one, and protective cover is by two parallel guide plate supportings of being fixed on the fixed form, and move protective cover front and back on this guide plate, and barrel and protective cover are independently of one another.During reach, protective cover is pressed abd fixed on the limit switch of fixed form, and injection mechanism is with start injection; Otherwise action of injection stops.The 2nd, protective cover is fixed on the fixed form, stay a side to be convenient to open the door, barrel and protective cover are independently of one another.When door is shut, compress limit switch, injection mechanism can be done action of injection; Otherwise action of injection stops.Per injection is accomplished, and does not move protective cover backward or does not open door, and limit switch still is in closure state.As this moment with moving behind the injection mechanism, nozzle and mould separating, injection mechanism still can be done action of injection, cause melt to splash, and operating personnel are caused many unsafe factors.Increased the perpendicularity requirement of depth of parallelism requirement, guide plate and fixed form between the guide plate simultaneously, processing cost is improved; The relative fixed of guide plate and fixed form brings certain workload also for replacing nozzle and screw rod.
Chinese patent 200720105967.1, the applying date is on January 26th, 2007, Granted publication day is on February 13rd, 2008; A kind of injection machine injection protector is disclosed; Solved the problems referred to above, but its individual layer protective cover barrier propterty is not enough, the long-play protective cover comes off easily; Cause melt to splash, operating personnel are damaged.
The utility model content
To the problems of the prior art, the technical problem that the utility model will solve is the security performance that strengthens protective cover.
To achieve these goals, the technical scheme of the utility model is: a kind of injection machine machine barrel protector, comprise protective cover, and said protective cover comprises the internal layer protective cover, is arranged on the outside outer protective cover of internal layer protective cover.
Further, be provided with the interlayer post between said outer protective cover and the internal layer protective cover.
Further, said interlayer post is arranged in the middle of the protective cover end, through being bolted between outer protective cover and the internal layer protective cover.
The utility model protective cover is set to inside and outside two-layer, and after long-term the use, when coming off appearred in outer protective cover, the internal layer protective cover still can play the effect of protection, has avoided melt to splash, and operating personnel are damaged.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, a kind of injection machine machine barrel protector comprises protective cover, and protective cover comprises internal layer protective cover 2, is arranged on the outer protective cover 1 of internal layer protective cover 2 outsides.
In order better outer protective cover 1 to be fixed together with internal layer protective cover 2, be provided with interlayer post 4 between said outer protective cover 1 and the internal layer protective cover 2; Said interlayer post 4 is arranged in the middle of the protective cover end, through being bolted between outer protective cover 1 and the internal layer protective cover 2.
The utility model protective cover is set to inside and outside two-layer, and after long-term the use, when coming off appearred in outer protective cover, the internal layer protective cover still can play the effect of protection, has avoided melt to splash, and operating personnel are damaged.
All simple distortion of under the situation that does not break away from the utility model core, making or modification all fall into protection scope of the present invention.
Claims (3)
