Abstract
The invention relates to a quick fixing and dismounting mechanism for a plastic mould insert block. The quick fixing and dismounting mechanism comprises a mould cavity, and an insert block is arranged in the cavity. The quick fixing and dismounting mechanism is characterized in that the inner side of the insert block is connected with a positioning rod, and the positioning rod extends into the cavity; a locking bayonet and an ejection chute are formed on the positioning rod, and a locking rod and an ejection rod are arranged in the cavity at one side of the locking bayonet and the ejection chute; the head part of the locking rod is matched with the locking bayonet, and the head part of the ejection rod is matched with the ejection chute; and a locking screw and an ejection screw are arranged at the bottom of the cavity, the locking screw is connected with the tail part of the locking rod, and the ejection screw is connected with the tail part of the ejection rod. According to the quick fixing and dismounting mechanism, the mould is not needed to be dismounted while the insert block is replaced, and the workload needing several hours or even several days in the past is finished in several minutes, so that the quick fixing and dismounting mechanism has the advantages of saving working hours and reducing the cost and being quick in mounting, safe and reliable, and avoiding the problem of shortening the service life of the mould, which is caused by constantly dismounting the mould.
Description
Technical field
The present invention relates to a kind of mould of plastics quick fixedly disassembly mechanism of inserting, belong to the mould of plastics field.
Background technology
At present, the inserting of mould of plastics (comprise cavity block and core insert) mounting means all is to adopt the bolt form, again from the back side or the surface carry out fasteningly, then, bolt hole is blocked up back with media such as red coppers.But if need inserting of exchange, it fixes and dismantles all very trouble this type of mounting means; Particularly change when inserting, need to put in order secondary mould and take apart to change and insert, need several hrs; Even several days time, the waste great amount of manpower and material resources is changed trouble.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of employing check lock lever and bayonet fittings fastening, push rod is extruded, and man-hour is saved in quick installation and removal, changes easily the mould of plastics quick fixedly disassembly mechanism of inserting.
Mould of plastics of the present invention is inserted fast fixedly, and the technical scheme of disassembly mechanism is: comprise mold cavity, install in the die cavity and insert, it is characterized in that the described inboard of inserting is connected with backstay; Backstay stretches in the die cavity; Be shaped on the locking bayonet socket on the backstay and eject skewed slot, in locking bayonet socket and the die cavity that ejects skewed slot one side, check lock lever and knock-pin are set, the head of check lock lever with lock bayonet socket and match; The head of knock-pin with eject skewed slot and match; Lock screw is installed and is ejected screw in the bottom of die cavity, lock screw is connected with the afterbody of check lock lever, ejects screw and is connected with the afterbody of knock-pin.
The mould of plastics of the present invention quick fixedly disassembly mechanism of inserting during installation, will be inserted and backstay is put into die cavity, the rotational lock screw, the dependence lock screw inserts check lock lever in the locking bayonet socket on the backstay, make insert fastening.When replacing is inserted, lock screw is back-outed, check lock lever is eased out; To eject screw again and be screwed into, and make knock-pin insert corresponding ejecting in the skewed slot, rely on the inclined-plane that ejects skewed slot; Backstay is extruded; The backstay band to insert and from die cavity, deviate from, and will insert and backstay taking-up fully from die cavity with hand or instrument at last, and is promptly replaceable.The fixedly disassembly mechanism of this programme is arranged at the side of die cavity; Need not to dismantle mould when replacing is inserted, script is needed the workload of several hours even several days, foreshorten in short a few minutes and accomplish; Saved the artificial cycle greatly; Reduce cost, quick for installation, safe, reliable, and avoided causing the problem of die life shortening because of continuous dismounting mould.
The mould of plastics of the present invention quick fixedly disassembly mechanism of inserting, described inserting can be connected through screw thread or I-shaped with backstay, connects fast, makes things convenient for.Wall is processed skew wall around described the inserting, extrude a bit as long as will insert, inclined wall part just with the whole empty avoidings of die cavity, inserting deviate to make things convenient for.
Description of drawings
Fig. 1 is the mould of plastics of the present invention quick fixedly disassembly mechanism structural representation of inserting.
The specific embodiment
The present invention relates to a kind of mould of plastics quick fixedly disassembly mechanism of inserting, as shown in Figure 1, comprise mold cavity 1; Install in the die cavity and insert 2, described inserting can be cavity block, but also can be that core is inserted; Not limited by accompanying drawing, it is characterized in that described 2 inboards of inserting are connected with backstay 3, backstay 3 stretches in the die cavity; Be shaped on locking bayonet socket 4 on the backstay 3 and eject skewed slot 5, in locking bayonet socket 4 and the die cavity 1 that ejects skewed slot 5 one sides, check lock lever 6 and knock-pin 7 are set, the head of check lock lever 6 with lock bayonet socket 4 and match; The head of knock-pin 7 with eject skewed slot 5 and match; Lock screw 8 is installed and is ejected screw 9 in the bottom of die cavity 5, lock screw 8 is connected with the afterbody of check lock lever 6, ejects screw 9 and is connected with the afterbody of knock-pin 7.During installation, will insert and 2 put into die cavity 1 with backstay 3, rotational lock screw 8 relies in the locking bayonet socket 4 that lock screw 8 inserts check lock lever 6 on the backstays 3, make insert 2 fastening.When replacing is inserted, lock screw 8 is back-outed, check lock lever 6 is eased out; To eject screw 9 again and be screwed into, and make knock-pin 7 insert corresponding ejecting in the skewed slot 5, rely on the inclined-plane that ejects skewed slot 5; Backstay 3 is extruded; Backstay 3 is being with to insert and 2 from die cavity 1, is being deviate from, and will insert with hand or instrument at last and backstay takes out from die cavity fully, and is promptly replaceable.The fixedly disassembly mechanism of this programme is arranged at the side of die cavity; Need not to dismantle mould when replacing is inserted, script is needed the workload of several hours even several days, foreshorten in short a few minutes and accomplish; Saved the artificial cycle greatly; Reduce cost, quick for installation, safe, reliable, and avoided causing the problem of die life shortening because of continuous dismounting mould.Described inserting 2 is connected through screw thread or I-shaped 10 with backstay 3, connects fast, convenient.The described wall of inserting around 2 is processed skew wall 11, extrude a bit as long as will insert, inclined wall part just with the whole empty avoidings of die cavity, insert and deviate to make things convenient for.
