Abstract
The utility model discloses an anti-receding machine door for an injection molding machine. The anti-receding machine door comprises a door body, a door wheel arranged on the door body, a guide rail which corresponds to the door wheel, and an in-place anti-collision block which is arranged on the door body; the anti-receding machine door is characterized in that: the guide rail is provided with an anti-receding device which comprise an S-shaped spring piece, and a fixing piece which fixes the rear part of the spring piece on the guide rail; and the front part of the spring piece is provided with a door closing transition section and a door opening transition section. When the machine door is closed, the door wheel runs on the guide rail; and the transition section in the spring piece is contacted with the door wheel well until the door wheel is completely enclasped by the spring piece. When the door is opened, the transition section in the spring piece can release the door wheel well, so the effect of opening and closing the door freely can be achieved, the spring piece enclasps the door wheel well, rebounding is prevented, and safety accidents are avoided.
Description
Technical field
The utility model relates to the injection machine gate, specifically, relates to a kind of injection machine anti-back gate.
Background technology
Injection machine in use exists the phenomenon that gate is opened automatically always, causes the frequent generation of security incident, is caused by two aspect reasons through analyzing mainly:
1. during the injection machine door-closing in-place and the collision of crashproof rubber, make crashproof rubber produce plastic deformation, when crashproof rubber resets, produce elasticity tension, thereby cause that gate opens automatically.
2. injection machine is when the folding mould, because lubricant effect is bad, and the complete machine vibrations that cause, thus cause that gate opens automatically.
When present most of injection machine manufacturer considers resilience in design, all be to make the safety door section of climbing clivia overcome resilience, but in actual use because safety door has certain weight, the mill sassafras coefficient ratio of trolley and track is less.The vibrations inertia force that had both caused during the folding mould is directly proportional with the weight of safety door, so the clivia that moment is easy to cross on the door track is opened voluntarily, causes security incident.
Summary of the invention
The technical problem that the utility model will solve is to overcome above-mentioned defective, provides a kind of and can prevent resilience, avoids the injection machine anti-back gate of security incident.
For addressing the above problem, the technical scheme that the utility model adopted is:
Injection machine anti-back gate; Comprise a body; Be installed in trolley on the body, with the corresponding guide rail of trolley and be arranged on the anti-collision block that puts in place on the body; It is characterized in that: anti-unloading device is installed on the said guide rail, and anti-unloading device comprises the spring leaf that is serpentine and the rear portion of spring leaf is fixed on the fixture on the guide rail, the front portion of said spring leaf be provided with close the door changeover portion with open the door changeover portion two parts.
Owing to adopted technique scheme, compared with prior art, at closing time, trolley is walked on guide rail in the utility model, and when touching spring leaf, excessive section in the spring leaf well contacts with trolley earlier, held tightly for this reason by spring leaf fully up to trolley.When opening the door, through excessive section in the spring leaf good trolley that discharges, reach switch door effect easily, spring leaf is held trolley tightly simultaneously, has prevented the generation of resilience, has avoided security incident.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structure for amplifying sketch map of spring leaf.
The specific embodiment
Embodiment:
Injection machine anti-back gate like Fig. 1, shown in Figure 2, comprises a body, is installed in trolley 2 on the body, with trolley 2 corresponding guide rails 5 and be arranged on putting in place the anti-collision block 6 on the body.On the said guide rail 5 anti-unloading device is installed, anti-unloading device comprises the spring leaf 3 that is serpentine and the rear portion of spring leaf is fixed on the fixture 4 on the guide rail, the front portion of said spring leaf be provided with close the door changeover portion with open the door changeover portion two parts.In the present embodiment, fixture is a bolt.
In the present embodiment, trolley 2 is walked on guide rail 5, and when trolley 2 contacted with spring leaf 3, the excessive section 7 of closing the door in the spring leaf 3 contacted with trolley 2 earlier, and after trolley 2 got into spring leaf 3 fully, spring leaf was through the elasticity tension parcel trolley 2 of self.Because spring leaf 3 has been held trolley 2 tightly at closing time, so machine vibration also is difficult for making safe trolley to deviate from automatically to open the door in using.When opening the door, through the excessively section 8 good trolleys that discharge that open the door in the spring leaf, it is free and relaxed to open the door.
