Description
Technical field
The present invention relates to technical field of mold, particularly a kind of PP large transfusion bottle preform mould of advancing glue based on three-clove style.
Background technology
The injection moulding quality of infusion bottle and Design of Dies and manufacturing have substantial connection, the success or failure of infusion bottle processing, depend on to a great extent Design of Dies effect and mould workmanship, and the structural element that Design of Dies will be considered have following some: 1, die joint: the contact surface that when namely mould is closed, die and punch cooperatively interact, selecting of its position and form, affected by the factors such as article shape and outward appearance, wall thickness, forming method, after-processing technology, mould-type and structure, release method and shaping machine structure; 2, running gate system: namely by the injection machine nozzle to the feeding-passage between die cavity, comprise sprue, runner, cast gate and cold slug well, particularly the selected win of gate location is conducive to molten plastic is full of die cavity under the good flow state, is attached to solid-state on goods and is left to is easy to eject and removed (except hot runner mould) with the cast gate cold burden when the die sinking in mould.
Traditional infusion bottle mould adopts single-point to advance glue, enter the notes chamber from chewing sharp injecting glue, when injecting glue, chew tip temperature high, energy consumption is large, and chews the reduction in service life of point, chew the speed quickening that point is worn, chew coordinating along with the production time increases between point and needle, its quality of fit also descends, and affects product quality.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of simple in structure, needle with chew point coordinates accurate and effectively reduce chew sharp temperature and energy savings advance the PP large transfusion bottle preform mould of glue based on three-clove style.
Purpose of the present invention is achieved through the following technical solutions: a kind of PP large transfusion bottle preform mould of advancing glue based on three-clove style, it comprises chews point, chews cover, annotates chamber, die lip, notes core retainer plate, annotates core and needle, chew point and be sleeved on the inside of chewing cover, the bottom of chewing cover coordinates with the notes top of chamber, bottom and the die lip top of annotating chamber are connected, the bottom of die lip is connected with the top of annotating core retainer plate, annotate core and be arranged on the inside of annotating core retainer plate, and the front end of annotating core passes die lip and stretches into the inside of annotating chamber, and the inside of annotating core is provided with cooling-water duct; Chew sharp inside and be provided with through hole, evenly be provided with at least three needle guide ledges on the inwall at through hole middle part, needle passes to be chewed the inner through hole of point and with the needle guide ledges, coordinates, and the space between adjacent two needle guide ledges and needle forms into the glue passage.
Described die lip is taper fit with annotating chamber and annotating coordinating between core retainer plate respectively.
Described needle, the axis of chewing point, chew cover, annotate chamber, die lip and notes core are same straight line.
The working face of described needle guide ledges is arc surface, and the working face of needle guide ledges and needle closely cooperate.
The present invention has the following advantages:
1, chewing on point three breach that offer along advancing the glue direction, the part of its protrusions coordinates with needle, realizes guide effect, from breach, advances glue, and it is simple in structure.
2, the mating surface of needle guide ledges is circular arc, with needle, realizes closely cooperating, and guidance quality is good, needle with chew point and coordinate precision.
3, adopt three-clove style to advance the mode of glue, effectively reduce and chew tip temperature, increase the service life of chewing point, and can effectively reduce energy resource consumption.

In figure: 1, needle, 2, chew point, 3, chew cover, 4, product, 5, annotate chamber, 6, die lip, 7, annotate core retainer plate, 8, annotate core, 9-cooling-water duct, 10-advance the glue passage, 11-through hole, 12-needle guide ledges.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, Figure 2 and Figure 3, a kind of PP large transfusion bottle preform mould of advancing glue based on three-clove style, it comprises chews point 2, chews cover 3, annotates chamber 5, die lip 6, annotates core retainer plate 7, annotates core 8 and needle 1, chew point 2 and be sleeved on the inside of chewing cover 3, the bottom of chewing cover 3 coordinates with notes 5 tops, chamber, bottom and die lip 6 tops of annotating chamber 5 are connected, the bottom of die lip 6 is connected with the top of annotating core retainer plate 7, annotate core 8 and be arranged on the inside of annotating core retainer plate 8, and the front end of annotating core 8 passes die lip 6 and stretches into the inside of annotating chamber 5, and the inside of annotating core 8 is provided with cooling-water duct 9; Chew sharp 2 inside and be provided with through hole 11, evenly be provided with at least three needle guide ledges 12 on the inwall at through hole 11 middle parts, needle 1 passes the through hole 11 of chewing sharp 2 inside and with needle guide ledges 12, coordinates, and the space between adjacent two needle guide ledges 12 and needle 1 forms into the glue path 10.
