Description
Technical field
The utility model belongs to the injection machine technical field, is specifically related to injection machine matched moulds safety device.
Background technology
On the existing vertical injection molding machine in order to protect the person and the safety of equipment, especially operative employee's hand safety, generally be provided with safety device, for example modal safety pole device is promptly movably being established safety pole on the patrix, establishes the insurance hole on fixing counterdie, when the insurance hole is blocked by block, safety pole can not pass the insurance hole, and upper and lower mould can't matched moulds, can guarantee operator's safety; Not enough is that above-mentioned safety device is after die sinking, the operator will take off the workpiece of injection formed on one side, Yi Bian also will adopt manual methods to promote block to block the insurance hole, will cause danger if the operator forgets this action, but also need to increase by one operational sequence, lowered operating efficiency.Chinese patent notification number CN200970883; name is called the utility model patent of " a kind of injection machine safety guard "; a kind of injection machine safety device is disclosed; form by stationary base mount, motor, metallic plate, wire and spring; only after pressing the operating switch of injection machine; metallic plate just can leave original position and the hole of stationary base mount upper surface is abdicated, and safety pole is passed, and mould could matched moulds.Utilize the measure of electric switch control safeties to have the low deficiency of safety coefficient during this matched moulds, at first owing to do not have the Open architecture that blocks for having to hide around the mould of vertical injection molding machine, staff and other foreign matters might be strayed into the mold center zone at any time, and be abnormally dangerous; Secondly, the fault rate that exists of electric switch and spring is higher relatively in general, and also there are certain fault rate in parts such as wire, and the multiple failure rate is the correlative connection that multiplies each other, and makes that set safeties safety coefficient is low.Yet protection operator's hand safety is should not leave things to chance, and should be safe against all possibilities.
Summary of the invention
The utility model technical issues that need to address are; overcome open around the vertical injection molding machine mould of prior art, safety guard or can not be automatically or the low defective of the many safety coefficients of layer of structure, provide a kind of and establish shutter and the utilization safety guard that mechanical chain can not have an accident mould because of the misoperation matched moulds when opening the door in mold periphery.
The purpose of this utility model is achieved by following technical proposals: a kind of vertical injection molding machine matched moulds machinery safety guard, comprise mould, and there is a side to be provided with safety pole at the patrix of mould, safety pole is provided with some roads cannelure; Be provided with the insurance hole of a up/down perforation at the counterdie of mould, described safety pole aligns mutually with described insurance hole, and the safety pole external diameter is less than the aperture in insurance hole; At left side, right side and the rear side of mould the shrouding of band door is installed respectively, moving door is equipped with in the front of mould, is provided with cammed surface below lower edge one end of moving door; With patrix the push rod of the level that is provided with on the counterdie of same side of safety pole is being installed, the push rod front end is provided with the block that a front side is the cannelure that snaps in described safety pole of concave arc shape, the rear end of push rod is provided with rolling bearing, and rolling bearing is corresponding with the cammed surface of described moving door lower edge.When pushing described moving door open, the cammed surface roof pressure rolling bearing of moving door lower edge, rolling bearing promotes push rod and drives block to advance, make block or retaining at the oral area in described insurance hole, or snap in the cannelure of safety pole, be that safety pole is blocked or block and can not be inserted through the insurance hole by block in a word, patrix also just can not be downwards and the counterdie matched moulds, can guarantee therefore that when moving door is opened mould can not unexpected matched moulds; Frictional force when rolling bearing being set can making cammed surface promote push rod is force of rolling friction, and moving door is moved easily.
As preferably, described push rod front end is connected with cross bar, and cross bar one end is provided with a through hole; There is a cylindrical section block rear end, on the cylindrical section buffer spring of cover be inserted in again later on cross bar through hole in, and mix at the tail end of cylindrical section and to be used to the back-up ring that prevents to deviate from, the hole of described cylindrical section and cross bar is for slidably cooperating; The push rod stage casing is with back-moving spring, and the front end of back-moving spring withstands the footstock that is located on the counterdie, and the adjustable ring that is enclosed within adjustably on the push rod is withstood in the rear end of back-moving spring.When mould was in die opening state, moving door was closed, and cammed surface breaks away from rolling bearing, and push rod is return original position by back-moving spring, and block breaks away from safety pole thereupon, for upper and lower mould matched moulds is got ready.
As preferably, the downside of the cannelure of described safety pole is shaped as taper seat, and the upside of cannelure is shaped as circular plane.When push rod is pushed safety pole to, block perhaps fails accurately to snap in the cannelure of safety pole, but withstand on the step of safety pole, block will utilize the roof pressure buffer spring and halt at this moment, when patrix continues when descending, the block front side slides to the taper seat position of cannelure, and makes the block front side continue to snap in forward cannelure along the taper seat of cannelure by means of the restoring force of buffer spring, be pressed on the plane of cannelure upside above block, it is descending to force patrix to stop.
As preferably, described push rod is located at the left side of counterdie, and safety pole is located at the left rear side of patrix, and the cammed surface of moving door lower edge is located at the following left end of moving door.The workpiece that injection moulding finishes because general injection operation worker adopts the right hand to take, and with left hand push-and-pull moving door, can only be moved to the left and open so moving door is set, also be located at the following left end of moving door with regard to the cammed surface that requires the moving door lower edge, push rod and safety pole are also by the corresponding requirements setting.
The beneficial effects of the utility model are:
1, all around seals during the mould matched moulds, guarantee that operator's hand and extraneous foreign matter can not be strayed into accidents caused;
2, safety pole automatically locks under the door opening state, need not manually-operated, avoids operate miss and improves work efficiency;
3, multiple protective, safety coefficient is big.
