Description
Technical field
The utility model relates to a kind of novel evacuated forming machine structure that is used for quickly manufacturing mould and part.
Background technology
At present, be used for the vacuum pouring former of fast mould manufacturing technology, its core institution generally is made up of vavuum pump, molding mass container and agitator, funnel and shaping mold cavity.This institution system is placed on moulding material in the molding mass container earlier and vacuumizes and stir in forming process, adopts the mode of unloading vacuum to form negative pressure then and makes in the moulding material injection moulding die cavity.There is following weak point in this shaping mechanism: the material multiselect that generally is used for type vacuum injecting and forming is with mixtures such as resin, plastics and corresponding promoter, catalyst, thereby, material mobile relatively poor, curing rate is fast, this has just caused under the vacuum negative pressure effect, material can not fully be filled in the shaping mold cavity, so forming part is second-rate.This drawback is particularly outstanding in thin-walled or large scale mould and part manufacturing.
The utility model content
For overcoming existing type vacuum injecting and forming machine above shortcomings, the utility model provides a kind of moulding material of realizing fully to fill up the novel evacuated forming machine structure of shaping mold cavity.
The technical scheme that its technical problem that solves the utility model adopts is: form by promoting rabbling mechanism, tipping mechanism and pressure injection mechanism, it is characterized in that: described lifting rabbling mechanism adopts lift agitator, liftably is installed in container and topples over a glass A top; Tipping mechanism by container topple over a glass A, container is toppled over a glass B and is constituted, the container that is used to topple over moulding material is toppled over a glass A and is positioned at lift agitator one side, topples over a glass B top in container; Pressure injection mechanism is the pusher pressure injection of a piston mechanism, form by perfusion casing, propelling piston and mould, perfusion casing top establish one can receive from container topple over the moulding material of glass B funnel, topple over a glass B below in container, propelling piston is installed in the perfusion casing, and the perfusion casing communicates with mould by output pipe.
Each part function of the utility model, interconnect and cooperation relation is:
Container is toppled over a glass A and is used for the splendid attire moulding material, and pours moulding material into container and topple among glass B under motor-driven; Container is toppled over glass B and is received the moulding material of toppling over glass A from container, utilizes the lifting rabbling mechanism to carry out the stirring of moulding material then; Pressure injection mechanism is used for receiving vessel and topples over the moulding material that glass B sends here, by output pipe moulding material is pressed in the shaping mold cavity under the effect of propelling piston then.
The beneficial effects of the utility model are:
1. have the characteristics that moulding material fully fills up shaping mold cavity.Unloading the negative pressure of vacuum formation with utilization compares the prior art that moulding material is pressed into shaping mold cavity, the utility model vacuum shape device is to utilize pressure injection mechanism to be pressed into moulding material in the shaping mold cavity effectively, moulding material and shaping mold cavity are fully fitted, realize that moulding material fully fills up the key technology of shaping mold cavity, thereby obtain superior in quality mould and manufactured part.
2. the utility model overall structure is simple, is convenient to design and makes, and can be applicable to the place of quickly manufacturing mould and part.
Description of drawings
Fig. 1 is the utility model structure chart.
The specific embodiment
Below in conjunction with accompanying drawing the structure of the present utility model and the course of work thereof are described in further detail.
As shown in Figure 1, the utility model is formed by promoting rabbling mechanism, tipping mechanism and pressure injection mechanism, wherein: lift agitator 1 liftably is installed in container and topples over a glass B3 top, described lifting rabbling mechanism adopts lift agitator 1, liftably be installed in container and topple over a glass A2 top, topple over moulding material among glass B3 by the agitator stirred vessel, tipping mechanism by container topple over a glass A2, container is toppled over a glass B3 and is constituted, container is toppled over a glass A2 and is positioned at lift agitator 1 one sides, topples over glass B3 top in container; Pressure injection mechanism 4 is the pusher pressure injection of a piston mechanism, can be divided into: perfusion casing 41, propelling piston 42 and mould 44, perfusion casing 41 tops are established one and can be received from container and topple over glass funnel of B3 moulding material, topple over a glass B3 side, below in container, propelling piston 42 is installed in 41 li of perfusion casings, and perfusion casing 41 communicates with mould 44 by output pipe 43.
Container is toppled over glass A2 and container and is toppled over a glass B3 and be used for the splendid attire moulding material, and can finish under motor-driven and topple over action; Lift agitator 1 is used for the moulding material that stirred vessel is toppled over glass B3, after stirring is finished, upwards promotes automatically; Pressure injection mechanism 4 receiving vessels are toppled over the moulding material that glass B3 sends here; Pressure injection mechanism 4 functions are: propelling piston 42 is pressed into moulding material in the shaping mold cavity 44 by output pipe 43.
The utility model course of work is:
Solidifying requirements according to mould material or part material, put into container after material mixed according to a certain percentage and topple over a glass A2, vacuumize, then container being toppled over moulding material among glass A2 slowly pours container into and topples among glass B3, continue while stirring to vacuumize, mix until material, send into then in the pressure injection casing 41, under propelling piston 42 effect, be injected at last through output pipe 43 mould 44 or framed in.
The utility model has adopted the pusher pressure injection of piston mechanism, because the propelling pressure controllability of piston is good, therefore can obtain good moulding material and paste mould, so the formed precision of product is higher, has also solved the problem that existing vacuum shape device exists simultaneously.
