Description

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

Technical field

The present invention relates to technical field of mold, particularly a kind of PP large transfusion bottle preform mould 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 Design of Dies effect and Making mold quality to a great extent, and the structural element that Design of Dies will be considered have following some: 1, die joint: the contact surface that when namely mould closes, die and punch cooperatively interact, its position and the selected of form, affect by factors such as article shape and outward appearance, wall thickness, forming method, after-processing technology, mould-type and structure, release method and shaping machine structures; 2, running gate system: namely by the feeding-passage between injection machine nozzle to 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, and to be attached on goods solid-state is left to and is easy to eject in mould with cast gate cold burden and is removed (except hot runner mould) when die sinking.

Traditional infusion bottle mould adopts single-point to enter glue, note chamber is entered from chewing sharp injecting glue, when injecting glue, chew tip temperature high, energy consumption is large, and the service life of chewing point reduces, chew the speed quickening that point is worn, chew and coordinate along with the production time increases between point with needle, its quality of fit also declines, and affects product quality.

Summary of the invention

The object of the invention is to the shortcoming overcoming prior art, provide that a kind of structure is simple, needle with chew point and coordinate accurate and effective reduction to chew sharp temperature and the PP large transfusion bottle preform mould entering glue based on three-clove style of economize energy.

Object of the present invention is achieved through the following technical solutions: a kind of PP large transfusion bottle preform mould entering glue based on three-clove style, it comprise chew point, chew cover, note chamber, die lip, note core retainer plate, note core and needle, chew point and be sleeved on the inside of chewing cover, the bottom of chewing cover coordinates with note top of chamber, bottom and the die lip top in note chamber are connected, the bottom of die lip is connected with the top of note core retainer plate, note core is arranged on the inside of note core retainer plate, and the front end of note core is passed die lip and stretched into the inside in note chamber, the inside of note core is provided with cooling-water duct; Chew sharp inside and be provided with through hole, the inwall in the middle part of through hole is 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 is formed into glue passage.

Described die lip is respectively with note chamber with to note coordinating between core retainer plate be taper fit.

Described needle, chew point, chew cover, note chamber, die lip and note core axis be 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 three breach point offered along entering glue direction, the part of its protrusions coordinates with needle, realizes guide effect, enters glue from breach, and its structure is simple.

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

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

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is the plan structure schematic diagram chewing point;

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.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described, 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 entering glue based on three-clove style, it comprise chew point 2, chew cover 3, note chamber 5, die lip 6, note core retainer plate 7, note 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 note top, chamber 5, bottom and die lip 6 top in note chamber 5 are connected, the bottom of die lip 6 is connected with the top of note core retainer plate 7, note core 8 is arranged on the inside of note core retainer plate 8, and the front end of note core 8 is passed die lip 6 and stretched into the inside in note chamber 5, the inside of note core 8 is provided with cooling-water duct 9; Chew sharp 2 inside and be provided with through hole 11, inwall in the middle part of through hole 11 is evenly provided with at least three needle guide ledges 12, needle 1 is through the through hole 11 chewing sharp 2 inside and coordinate with needle guide ledges 12, and the space between adjacent two needle guide ledges 12 and needle 1 is formed into glue path 10.

Described die lip 6 is respectively with note chamber 5 with to note coordinating between core retainer plate 7 be taper fit.

Described needle 1, chew point 2, chew cover 3, note chamber 5, die lip 6 and note core 8 axis be same straight line.

The working face of described needle guide ledges 12 is arc surface, and the working face of needle guide ledges 12 and needle 1 closely cooperate.

During non-injecting glue, needle 1 stretches into chews sharp 2 bottoms, and coordinates with the bottom of chewing point 2, realize sealing, during injecting glue mold filling, needle 1 moves up, needle 1 and chew point 2 between formed into glue passage, glue is entered from the breach between needle guide ledges 12, be full of mold cavity, after being full of, needle 1 resets, the demoulding, obtains product 4.
