Abstract
The invention discloses a tool edge cutting mechanism for an injection mold and relates to the technical field of molds. The tool edge cutting mechanism comprises a tool edge, a tool edge protection rod, a runner ejector pin, a mold plate limit rod and a resin parting lock. The tool edge protection rod is arranged on one side of the tool edge. The tool edge is matched with a runner. The runner ejector pin is installed below the runner. The mold plate limit rod is installed on a moving mold plate and a moving mold bearing plate. The tool edge and the tool edge protection rod are fixed to the moving mold bearing plate. The resin parting lock is further installed on the moving mold plate. A hanging table of the tool edge is 2 mm lower than a hanging table of the tool edge protection rod. The tool edge protection rod protects the tool edge against cracks in the cutting process. Through the tool edge cutting mechanism, labor cost is lowered, the production efficiency is improved, the product percent of pass is increased, the production cost is low, practicability is high, and application and popularization are easy.
Description
Technical field
The present invention relates to technical field of mold, particularly relate to injection mold edge of a knife material cutting mechanism.
Background technology
In Design of Dies, only Jiao Kou, the Jiao Kou that hides are selected in employing, Fructus Musae glue eloquence can be at mould
Tool is separated, mechanical hand fully-automatic production could be used aborning.Owing to product structure limits
System, the mould using the mouth of a river, side is more, need to put into a large amount of manpower and prune Jiao Kou during production, due to
The hands of people by mistake, also can cut injured labor product, and conforming product rate reduces；If infusion of financial resources makes blank
Head tool, too increases equipment cost, human cost equally, does not has competitiveness.
Face between prices of raw materials rise, labor cost raising, industry with current each enterprise
The present situation that dog-eat-dog, production unit cost are relatively low, can only go raising to optimize at technical elements, therefore,
Those skilled in the art is devoted to develop a kind of injection mold edge of a knife material cutting mechanism.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide
A kind of injection mold edge of a knife material cutting mechanism, simple in construction, reasonable in design, automated production,
Reducing human cost, improve production efficiency and conforming product rate, production cost is low, practicality
By force, it is easy to promote the use of.
For achieving the above object, the invention provides injection mold edge of a knife material cutting mechanism, including
The edge of a knife, edge of a knife guard bar, runner ejector pin, resin shutter and being used for limit moving platen (7) with
The restriction template limit rod of spacing between dynamic model board (8), edge of a knife side is provided with edge of a knife protection
Bar, the edge of a knife matches with runner, and the lower section of runner is provided with runner ejector pin, and template limit rod is pacified
Being contained on moving platen and dynamic model board, the edge of a knife, edge of a knife guard bar are fixed on dynamic model board, dynamic
Resin shutter it is also equipped with in template.
As preferably, the mating shapes of the shape of the described edge of a knife and runner front end, the extension of the edge of a knife
The low 2mm of hanging platform height of platform aspect ratio edge of a knife guard bar, the edge of a knife guard bar protection edge of a knife is at blank
During will not rupture.
As preferably, the upper end apical grafting of described runner ejector pin on runner, the lower end of runner ejector pin
It is fixed on liftout plate, by liftout plate, runner is ejected from the edge of a knife.
As preferably, one end of described resin shutter is arranged on moving platen, resin opening and closing
The other end of device matches with dynamic model board, it is achieved folding.
The invention has the beneficial effects as follows: during (1) forming machine die sinking, Jiao Kou synchronizes quilt in a mold
Mould opening force cuts off, and does not increase life cycle of the product；
(2) decrease cut glue mouth tool exploitation put into；
(3) human input in process of producing product is decreased；
(4) improve production efficiency and produce yield.
Below with reference to accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is made
Further illustrate, to be fully understood from the purpose of the present invention, feature and effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation that edge of a knife guard bar of the present invention separates with runner；
Fig. 3 is the structural representation that the edge of a knife of the present invention separates with runner section；
Fig. 4 is the structural representation that the edge of a knife of the present invention is kept completely separate with runner.
Detailed description of the invention
With reference to Fig. 1-4, this detailed description of the invention by the following technical solutions: injection mold cutter
Mouth material cutting mechanism, including the edge of a knife 1, edge of a knife guard bar 2, runner ejector pin 3, template limit rod 4
With resin shutter 5, the edge of a knife 1 side is provided with edge of a knife guard bar 2, the edge of a knife 1 and runner 6
Matching, the shape of the edge of a knife 1 and the mating shapes of runner 6 front end, the hanging platform of the edge of a knife 1 is high
Spend the low 2mm of hanging platform height than edge of a knife guard bar 2, make edge of a knife guard bar 2 cut than the edge of a knife 1
First move during material 2mm, and the protection edge of a knife 1 will not rupture during blank, so that thing
Part 10 is smoothly detached with runner 6, and the lower section of runner 6 is provided with runner ejector pin 3, and template limits
Position bar 4 is arranged on moving platen 7 and dynamic model board 8, and the edge of a knife 1, edge of a knife guard bar 2 are fixed
On dynamic model board 8, moving platen 7 is also equipped with resin shutter 5.
It should be noted that the upper end of described runner ejector pin 3 passes quiet template apical grafting at runner 6
On, the lower end of runner ejector pin 3 is fixed on liftout plate 9, by liftout plate 9 by runner 6 from
The edge of a knife 1 ejects.
Additionally, one end of described resin shutter 5 is arranged on moving platen 7, resin opening and closing
The other end of device 5 matches with dynamic model board 8, it is achieved folding.
This detailed description of the invention, during mould die sinking, can run three below step: (1)
The active force produced with resin shutter 5 by the elastic force of spring in template limit rod 4, will be dynamic
Template 7 separates 2mm with dynamic model board 8, and now edge of a knife guard bar 2 moves down 2mm, with
Runner 6 separates (Fig. 2).
(2) when template limit rod 4 is spacing, the edge of a knife 1 moves downward 2mm, and now the edge of a knife 1 will
Runner 6 separates with object 10, and edge of a knife guard bar 2 concedes 4mm space, prevents runner 6 folding
Time curved, stress is excessive, thus protects the edge of a knife 1 (Fig. 3).
(3) liftout plate 9 action, drives runner ejector pin 3 to eject, by runner 6 from the edge of a knife 1
Eject (Fig. 4), now can take out object 10 and runner 6 with mechanical hand simultaneously, this mechanism
Action completes.
This detailed description of the invention utilizes the power of forming machine die sinking, by special mechanism driven mold cutter
Object is cut off with Jiao Kou and separates by mouth, and this mechanism completed in mould die sinking moment, did not the most increase
Add the production time, the most effectively solve manpower and cut Jiao Kou, put into tool and cut the production that Jiao Kou causes and become
This high problem, strengthens enterprise competitiveness, has wide market application foreground.
The preferred embodiment of the present invention described in detail above.Should be appreciated that this area
Those of ordinary skill just can make many according to the design of the present invention without creative work
Modifications and variations.Therefore, all technical staff in the art are under this invention's idea existing
By the available technical side of logical analysis, reasoning, or a limited experiment on the basis of technology
Case, all should be in the protection domain being defined in the patent claims.
