Abstract
The utility model relates to an injection protective device of an injection machine, and the device is designed to aim at the problem that an existing injection mechanism is easy to generate the melting material splashing which causes the unsafe factors to an operator when injecting. The device consists of a protective cover, a material barrel cover casing, a material barrel, a limiting switch, a fixed die plate, and an injection component. The utility model is characterized in that the material barrel cover casing is connected with a guide plate, the guide plate is connected with the protective cover in a sliding way; a sliding plate is arranged in the protective cover, the guide plate is provided with a guide groove, the sliding plate is connected with the guide groove in a sliding and matching way. Before the injection state of the injection machine, the protective cover and the limiting switch are not in place, the injection can not be operated. The protective cover and the limiting switch are in place, the injection can be operated, to ensure the protective cover really play the protective effect. The safety preventive measure of the operator is enhanced, and the problem of the unsafe factor caused by the non ideal design of an original injection machine injection protective device is solved, to ensure that the overall technology content of the injection machine is greatly improved.
Description
Technical field
The utility model relates to injection machine injection protector.
Background technology
The injection protection mechanism that existing injection machine generally adopts has two kinds substantially: 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 finished, not mobile backward protective cover or do not open door, and limit switch still is in closure state.As will move behind the injection mechanism this moment, 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.
Summary of the invention
The utility model will overcome above-mentioned deficiency, and purpose is to provide comparatively reasonably injection machine injection protector of a kind of design, the safety problem when making it can solve the injection mechanism inject state to this area.The purpose of this utility model is to adopt following technical scheme to realize.
A kind of injection machine injection protector, this device comprises protective cover, barrel case, barrel, limit switch, fixed form, injection member, limit switch is housed on fixed form, injection member connects barrel, the barrel case is set on the barrel, its main points are that the barrel case connects guide plate, and guide plate slides connects protective cover; Sliding panel promptly is set in protective cover, and guide plate is provided with gathering sill, sliding panel and gathering sill sliding connection.
Described guide plate and barrel case are connected and fixed by screw.
The sliding panel of the fixedly connected Baltimore groove of cover inner top of described protective cover, the position of sliding panel fixed form is corresponding setting with limit switch.
It is undesirable that the utility model has solved the design of original injection machine injection protector, brings the problem of unsafe factor.Before the injection machine inject state, protective cover just can not be injected with not in place with limit switch.Put in place and just can inject, make protective cover real play protective action.Improved operator's safe precaution measure, operating efficiency, injection machine general technical content is greatly improved.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model off working state schematic diagram.
Fig. 3 is the utility model working state schematic representation.
Above figure number and title: 1, protective cover, 1.1, sliding panel, 2, screw, 3, guide plate, 3.1, gathering sill, 4, the barrel case, 5, barrel, 6, limit switch, 7, fixed form, 8, injection member.
The specific embodiment
The specific embodiment is in conjunction with Fig. 1～shown in Figure 3, and injection member 8 belongs to signal to be drawn, and screw 2 is fixed on guide plate 3 on the barrel case 4.When operating personnel pass duty extremely shown in Figure 3 with protective cover, be that injection machine just can carry out the melt injection, protective cover 1 is to be slidingly matched by the sliding panel 1.1 of the Baltimore groove of establishing in it and the gathering sill 3.1 of guide plate 3 both sides, and protective cover puts in place and withstands limit switch 6.Have only artificially with protective cover and fixed form 7 uncouplings, make the limit switch dislocation, when being about to move to off working state shown in Figure 2 behind the protective cover, injection machine does not just carry out melt and injects.Protective cover 1 seesaws when limit switch dislocate with barrel 5 to be synchronous, also to be synchronous when limit switch is spacing, and difference is that protective cover and fixed form are collided and connects, and when spacing, injection machine just carries out melt to be injected, otherwise does not inject by limit switch.Thoroughly get rid of the possibility that still can inject behind nozzle and the mould separating, play that injection machine security when injecting is higher, the purpose of more convenient operation.
Claims (3)
