Description

A kind of PP large transfusion bottle preform mould of entering glue based on three-clove style

Technical field

The utility model relates to technical field of mold, particularly a kind of PP large transfusion bottle preform mould of entering glue based on three-clove style.

Background technology

The injection moulding quality of infusion bottle and Design of Dies and manufacture 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 mould is closed, die and punch cooperatively interact, selecting of its position and form, is 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: by 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 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 cast gate cold burden when the die sinking in mould.

Traditional infusion bottle mould adopts single-point to enter glue, from chewing sharp injecting glue, enter notes chamber, when injecting glue, chew tip temperature high, energy consumption is large, and chews sharp service life and reduce, 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 declines, and affects product quality.

Utility model content

The purpose of this utility model 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 the saving energy based on three-clove style, enter the PP large transfusion bottle preform mould of glue.

The purpose of this utility model is achieved through the following technical solutions: a kind of PP large transfusion bottle preform mould of entering glue based on three-clove style, it comprises chews point, chews cover, notes chamber, die lip, notes core retainer plate, notes core and needle, chew point and be sleeved on the inside of chewing cover, the bottom of chewing cover coordinates with notes top of chamber, bottom and the die lip top of noting chamber are connected, the bottom of die lip is connected with the top of noting core retainer plate, note core and be arranged on the inside of noting core retainer plate, and the front end of noting core passes die lip and stretches into the inside of noting chamber, and the inside of noting core is provided with cooling-water duct; Chew sharp inside and be provided with through hole, on the inwall at through hole middle part, be evenly provided with at least three needle guide ledges, needle is through chewing the inner through hole of point and coordinating with needle guide ledges, and the space between adjacent two needle guide ledges and needle forms into glue passage.

Described die lip is taper fit with noting chamber and noting coordinating between core retainer plate respectively.

Described needle, the axis of chewing point, chew cover, note 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 utlity model has following advantage:

1, chewing three breach that offer on point along entering glue direction, the part of its protrusions coordinates with needle, realizes guide effect, from breach, enters glue, and it is simple in structure.

2, the mating surface of needle guide ledges is circular arc, realizes and to closely cooperate with needle, and guidance quality is good, needle with chew point and coordinate precision.

3, adopt three-clove style to enter the mode of glue, effectively reduce and chew tip temperature, increase and chew sharp service life, and can effectively reduce energy resource consumption.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 chews sharp plan structure schematic diagram;

Fig. 3 is A-A sectional structure schematic diagram in Fig. 2;

In figure: 1, needle, 2, chew point, 3, chew cover, 4, product, 5, note chamber, 6, die lip, 7, note core retainer plate, 8, note core, 9-cooling-water duct, 10-enters glue passage, 11-through hole, 12-needle guide ledges.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model 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 entering glue based on three-clove style, it comprises chews point 2, chews cover 3, notes chamber 5, die lip 6, notes core retainer plate 7, notes core 8 and needle 1, chew point 2 and be sleeved on the inside of chewing cover 3,5 tops, Yu Zhu chamber, bottom of chewing cover 3 coordinate, bottom and die lip 6 tops of noting chamber 5 are connected, the bottom of die lip 6 is connected with the top of noting core retainer plate 7, note core 8 and be arranged on the inside of noting core retainer plate 7, and the front end of noting core 8 passes die lip 6 and stretches into the inside of noting chamber 5, and the inside of noting core 8 is provided with cooling-water duct 9; Chew sharp 2 inside and be provided with through hole 11, on the inwall at through hole 11 middle parts, be evenly provided with at least three needle guide ledges 12, needle 1 is through chewing the through hole 11 of sharp 2 inside and coordinating with needle guide ledges 12, and the space between adjacent two needle guide ledges 12 and needle 1 forms into glue path 10.

Described die lip 6 is taper fit with noting chamber 5 and noting coordinating between core retainer plate 7 respectively.
