Description
Technical field
This utility model is related to injection molding field, specifically a kind of injecting mechanism.
Background technology
Injection machine is that thermoplastic or thermosetting material are made into variously-shaped plastic using mould for plastics
Main former.Injection machine can be divided into vertical, horizontal and vertical sleeping multiple according to injection device and the arrangement mode of clamping apparatus
It is box-like.Injection machine has can one-shot forming external form complexity, the plastic that accurate size or the quality with metal insert are dense
Ability, be widely used in national defence, electromechanics, automobile, transportation, building materials, packaging, agricultural, culture, education and public health and people daily
Various fields of recent life.In today that plastics industry is developed rapidly, no matter injection machine quantitatively or in kind all occupies importantly
Position, becoming increase in current plastics machinery most fast, one of most machine of production quantity.
But because the rotary speed of heating spiral rod is affected by plastic solution viscosity and security standpoint, heating spiral rod
Rotary speed is relatively low, and the plastics of plasticizing can not be sufficiently stirred for, and plastifies lack of homogeneity, in order to fully plastify, some prior arts,
Plasticizing efficiency and uniformity being improved by increasing the length of screw rod, but being limited to the volume of heating chamber, this design effect is failed to understand
It is aobvious, and efficiency is low.
Utility model content
The purpose of this utility model be in order to solve prior art in plastify lack of homogeneity, stir not sufficient enough defect,
There is provided a kind of injecting mechanism to solve the above problems.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of injecting mechanism, including hopper, heating chamber, heating spiral rod and cast gate connection end, the hopper is located at heating
Chamber roof one end, the feed hopper bottom is communicated with heating chamber, and the heating spiral rod is described to add along heating chamber axial restraint
Hot screw rod is coaxial with heating chamber, and the heating spiral rod is located at hopper lower section, is crisscross arranged in the excircle of the heating spiral rod
Several agitating devices, hang plate, the hang plate are arranged in the heating chamber near the both sides of one end of cast gate connection end
One end is connected with heating chamber, and the other end connects with cast gate connection end, in the space formed between hang plate and heating chamber
At least one cooling bath is also set up, the hopper side wall also sets up exhaust apparatus.
Preferably, the agitating device is stirring paddle.
Preferably, the exhaust apparatus includes air vent and exhaust cap, and the exhaust cap is rotationally connected with hopper outside.
Compared with prior art, the beneficial effects of the utility model are：1）Arranging agitating device causes plastics to be heated thawing
After can be sufficiently mixed；2）Along the loss and temperature of the melt during flowing due to energy of heating chamber wall flow
Reduce and form cold burden, arranging cooling bath can absorb these cold burdens, so as to ensure to be molded quality.

Specific embodiment
To make to have a better understanding and awareness architectural feature of the present utility model and the effect reached, to compared with
Good embodiment and accompanying drawing coordinates detailed description, is described as follows：
A kind of injecting mechanism, including hopper 1, heating chamber 2, heating spiral rod 3 and cast gate connection end 4, the hopper 1 is located at
The top one end of heating chamber 2, the bottom of the hopper 1 communicates with heating chamber 2, and the heating spiral rod 3 is axially solid along heating chamber 2
Fixed, the heating spiral rod 3 is coaxial with heating chamber 2, and the heating spiral rod 3 is located at the lower section of hopper 1, in the heating spiral rod 3
Excircle is crisscross arranged several agitating devices 5, arranges near the both sides of one end of cast gate connection end 4 in the heating chamber 2
Hang plate 6, one end of the hang plate 6 is connected with heating chamber 2, and the other end connects with cast gate connection end 4, hang plate 6 with plus
At least one cooling bath 7 is also set up in the space formed between hot chamber 2, the side wall of the hopper 1 also sets up exhaust apparatus.
When injecting mechanism works, plastic raw materialss, plastic raw materialss are added to enter the post-heating screw rod 3 of heating chamber 2 into hopper 1
Rotate and plastic raw materialss heated, while the agitating device 5 that the excircle of heating spiral rod 3 is crisscross arranged rotates with heating spiral rod 3, pair plus
Plastic melt after heat is melted is stirred, melt during flowing to die cavity, along the molten of the medial wall of heating chamber 2 flowing
Material can form cold burden with the loss of energy in flow process and the reduction of temperature, be arranged in hang plate 6 and heating chamber 2
Cooling bath 7 cold burden can be siphoned away, it is constant so as to ensure the melt temperature for flowing through cast gate connection end 4, come so as to ensure to be molded by
Product quality stablize.When plastic raw materialss continue into heating chamber 2, due to the high temperature produced in heating chamber 2, air is received
Hot pressing increases by force, and the exhaust cap 9 in the outside of hopper 1 is backed down, and hot-air can be discharged in time by air vent 8, can effectively be prevented
Air enters heating chamber 2, and because air is entered after heating chamber 2, the pressure in heating chamber 2 can be caused to increase, when
When pressure in heating chamber 2 is much, then security incident can occur, the setting of exhaust apparatus can effectively prevent security incident
Generation.
Ultimate principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, this utility model also has respectively on the premise of without departing from this utility model spirit and scope
Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed this utility model.This utility model is required
Protection domain defined by appending claims and its equivalent.
