Description

A kind of injection mold of end with tooth mouth
Technical field
The present invention relates to a kind of injection molds, and in particular to a kind of injection mold of end with tooth mouth.
Background technology
With the rapid development of China's economy and society, people are higher and higher to the quality requirement of various plastic products, band There are flaw or the plastic products of damage to be undoubtedly eliminated, during production, when on plastic article have with die sinking direction not When there is concaveconvex shape in consistent hole or side wall, it is necessary to which the core of moulding section or cavity are detached from plastic article first can just make entirely Plastic article is removed from the mold.If ejection technique falls behind the destruction that can cause finished product, economic loss is caused to businessman.To obtain The band tooth mouth plastic products of high quality are obtained, Injection Mold Design is critically important.Occur realizing using inclined guide pillar slide block structure in the market Inner side core-pulling, complicated because to there is the tracks of sliding block during core pulling, cost increases.
Invention content
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of injection mold of end with tooth mouth, if Some angle ejector rod slide block mechanisms realize side core-pulling, so as to simplify mould structure, reduce die cost.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
A kind of injection mold of end with tooth mouth including sprue bush, top clamping plate, the first guide post, the second guide post, solid plate, moves Template, the first mandril, the second mandril, mandril fixed plate, Bottom clamp plate, sliding block;Sprue bush, institute are equipped among the cover half pedestal It states and is equipped with solid plate, moving platen, support block, Bottom clamp plate under top clamping plate successively;Above the Bottom clamp plate by cushion block successively Accept push plate and mandril fixed link;The Bottom clamp plate is equipped with and to sequentially pass through push plate, mandril fixed plate, moving platen second are led Column;The push plate is equipped with the first mandril and the second mandril for sequentially passing through mandril fixed plate, moving platen;The solid plate and dynamic The sliding block for abutting die cavity is equipped between template, the first guide post through sliding block is equipped with below the solid plate.
Preferably, the first guide post angle of inclination is 135 °.
Preferably, the second guide post both sides are equipped with spring.
Preferably, the sprue of the pouring head is set as cone, and cone angle is 4 °.
Preferably, the sprue inner surface is smooth, 0.4 μm of roughness.
Preferably, the first mandril bottom is equipped with guide rail.
Preferably, the sprue bush injection molding channel includes spot pouring mouth and side gate.
The invention has the beneficial effects that:Injection mold of the end with tooth mouth of the present invention, using spot pouring mouth and side gate With reference to structure type from moulding side into pouring, to make cast gate hidden, there are traces on the main external appearance of moulding. Select inclined guide pillar sliding block core-pulling mechanism and angle ejector rod core-pulling mechanism, will not be damaged during demoulding the plastics with mouth with teeth into Product.Its is simple in structure, easy to operate, at low cost, is with a wide range of applications.

Specific embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figs. 1-3, injection mold of a kind of end with tooth mouth, including sprue bush 13, top clamping plate 1, the first guide post 2nd, the second guide post 10, solid plate 4, moving platen 5, the first mandril 6, the second mandril 15, mandril fixed plate 11, Bottom clamp plate 8, sliding block 3;Sprue bush 13 is equipped among the cover half pedestal 1, be equipped with successively under the top clamping plate 1 solid plate 4, moving platen 5, support block 7, Bottom clamp plate 8;Accept push plate 12 and mandril fixed link 11 successively by cushion block in 8 top of Bottom clamp plate;The Bottom clamp plate 8 Be equipped with sequentially pass through push plate 12, mandril fixed plate 11, moving platen 5 the second guide post 10;The push plate 12 is equipped with and passes through successively Wear mandril fixed plate 11, moving platen 5 the first mandril 6 and the second mandril 15;It is equipped with and supports between the solid plate 4 and moving platen 5 The sliding block 3 of die cavity is connect, 4 lower section of solid plate is equipped with the first guide post 2 through sliding block 4, and the first guide post inclination angle is 135°。
The second guide post both sides are equipped with spring 9, convenient for mandril fixed plate 11 is pushed to reset.
The sprue of the sprue bush 13 is set as cone, and cone angle is 4 °, and sprue inner surface is smooth, 0.4 μ of roughness M, in order to the abjection of runner condensate.13 injection molding channel of sprue bush includes form that spot pouring mouth and side gate combine from moulding side Face is into pouring, and to make cast gate hidden, does not leave a trace on the main external appearance of moulding.
First mandril, 6 bottom horizontally slips equipped with guide rail convenient for the first mandril 6.
The operation principle of injection mold is:
When mold is closed, the plastics of melting inject mold cavity by sprue bush 13, and after injection moulding, injection molding machine drives Moving platen is moved down with lower portion, the parting between moving platen and solid plate, as moving platen 5 continues to move down, sliding block 3 realize side core-pulling under the effect of the first guide post 2;Under the action of sprue puller, plastic article stays in dynamic model side, remaining in main running channel Material is slowly extracted.After clout in main running channel is extracted, dynamic model 5 and cover half 4 continue to detach, until having enough between two plates Space is to ensure that plastic article can be completely removed.At this moment, injection molding machine and dynamic model stopping move downward, and the mandril in injection molding machine is consolidated Fixed board moves upwards, and the second mandril 15 ejects extra clout, and the first mandril 6 is also suitable while being moved upwards with Bottom clamp plate Inclined hole side-to-side movement in Bottom clamp plate 8, realizes the separation of the first mandril 6 and plastic article, while makes plastic article from dynamic model Ejection.After plastic article is removed, the push rod of push plate 12 is pushed to reset, the push plate under the action of the second guide post 10 and resetting spring 9 12 return to original position, the first mandril 6 and the second mandril 15 also with being returned to original position.Mold starts to be closed, moving platen 5 The distance between solid plate 4 is less and less, until being closed completely, completes a cycle.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should Understand, the invention is not limited in any way above-described embodiment, all to be obtained by the way of equivalent substitution or equivalent transformation Technical solution is all fallen in protection scope of the present invention.
