Specific embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
As Figure 1-4, the embodiment of the present application is dived under water into formula injection mold is poured there is provided one kind, and the diving for being provided enters to pour
Formula injection mold includes rear mold 10, and rear mold 10 includes rear mold main body 100 and oblique top 101, and oblique top 101 is arranged on rear mold main body 100
On, oblique top 101 is used for the deep position of bone feature of forming plastic cement product.
It is provided with rear mold main body 100 and is dived under water into cast gate 100a and insufflation channel 100b, oblique top 101 is provided with convergence hole
101a, convergence hole 101a can connect insufflation channel 100b and dive under water into cast gate 100a with the ejection of oblique top 101.
During work is molded, what the embodiment of the present application was provided dives under water into the front mould 20 for pouring formula injection mold, front mould
20 include preceding die holder 200 and front cavity 201, and front cavity 201 is arranged on preceding die holder 200, dives under water into after pouring formula injection mold
Mould 10 includes rear mold main body 100 and oblique top 101, and rear mold main body 100 includes rear die holder 100c and rear cavity 100d, rear cavity 100d
On rear die holder 100c, after front mould 20 and the matched moulds of rear mold 10, front cavity 201 is with rear cavity 100d and oblique top 101 constitutes note
Mold cavity, offers cast passage 202 on front mould 20, cast passage 202 is connected into cast gate 100a by diving under water with injection mold cavity.
The material of injection is entered into injection mold cavity by diving under water from cast passage 202 into cast gate 100a, so as to be molded to form plastic cement product
Product 30, as depicted in figs. 1 and 2.
The demoulding of front mould 20 and rear mold 10 plastic cement products 30 after realization die sinking in the presence of oblique top 101 and push rod 100e,
Because rear mold main body 100 is provided with to dive under water convergence hole is provided with cast gate 100a and insufflation channel 100b, and oblique top 101
101a, in the presence of the jacking mechanism 100f in rear mold 10, by jack-up, convergence hole 101a can be with for oblique top 101 and thimble 100e
The ejection of oblique top 101 and connect and insufflation channel 100b and dive under water into cast gate 100a, the air-flow in insufflation channel 100b can blow to latent
Water enters cast gate 100a, and then the rubber powder dived under water into cast gate 100a is blown away, and as shown in Figures 3 and 4, the arrow in Fig. 3 and Fig. 4 is
Air current flow direction.
Can be drawn by the above-mentioned course of work, the diving that the embodiment of the present application is provided enters to pour in formula injection mold, oblique top
Convergence hole is provided with 101, is provided with rear mold main body 100 and dived under water into cast gate 100a and insufflation channel 100b, in plastic cement products
During 30 demouldings, oblique top 101 by the jack-up of plastic cement products 30 and then can realize the demoulding, convergence hole 101a with oblique top 101 top
Go out and connect insufflation channel 100b and dive under water into cast gate 100a, the air-flow in insufflation channel 100b can be entered by convergence hole 101a
Dive under water into cast gate 100a, the rubber powder most dived under water at last into cast gate 100a blows away, it is seen then that the diving that the embodiment of the present application is provided
Entering to pour formula injection mold and solving to dive under water pile up problem into pouring the rubber powder that injection molding manner produces in process of production, and then is avoided that
The damage of components of the injection mold caused by rubber powder is piled up.
In the embodiment of the present application, insufflation channel 100b can realize quickly being connected by snap joint and source of the gas, and source of the gas can
Being gas cylinder or high-pressure pump.In order to ensure more effectively being purged to the rubber powder into cast gate 100a of diving under water, refer to Fig. 1 and
The outlet side of Fig. 3, insufflation channel 100b is variable cross-section outlet side 100ba, and variable cross-section outlet side 100ba is in gas flow direction
Cross-sectional area is gradually reduced, and variable cross-section outlet side 100ba can play acceleration air-flow, strengthens the effect of gas flow purging dynamics, and then
The cleaning effect to rubber powder can be improved.
Referring again to Fig. 1 and Fig. 3, in a kind of specific embodiment：Insufflation channel 100b can include isometrical section
100bb and accelerating sections, the outlet side of isometrical section of 100bb connect with accelerating sections, and accelerating sections is variable cross-section outlet side mentioned above
100ba.Variable cross-section outlet side 100ba can be conical outlet side.After air-flow enters in insufflation channel 100b, isometrical section
100bb can realize the smooth flow of air-flow, and air-flow is mainly advanced in laminar flow in such cases, be conducive to follow-up accelerated section adding
Speed and quickly flowed along soot blowing wind direction.
As described above, rear mold main body 100 includes that rear die holder 100c and rear cavity 100d, rear cavity 100d are arranged on rear mold
On seat 100c, insufflation channel 100b extends to rear die holder 100c and rear cavity 100d successively, and insufflation channel 100b extension side
To with dive under water it is perpendicular into the stripping direction for pouring formula injection mold so that insufflation channel 100b can with shorter path to
And extend into the direction of cast gate 100a near diving under water, so can reduce air blasting passage 100b open up difficulty.
In a kind of specific embodiment, on the airflow direction of the outlet side of insufflation channel 100b, insufflation channel 100b
Outlet side with dive under water positioned opposite into the discharging port of cast gate 100a, enable to air-flow more direct to blowing for rubber powder.
Preferably, on the airflow direction of the outlet side of insufflation channel 100b, the projection of the outlet side of insufflation channel 100b is located at linking
In the inlet end end on projection of hole 101a.This kind of structure enables to the air-flow that the outlet side of insufflation channel 100b is discharged can to use up
May more flow in convergence hole 101a, reduce windage loss.
On the airflow direction of the outlet side of insufflation channel 100b, the projection into the discharging port of cast gate 100a of diving under water is located at
In the outlet side end on projection of convergence hole 101a, this kind of arrangement can ensure that the air-flow discharged from the outlet side of convergence hole 101a
Implement comprehensive purging into cast gate 100a to that can dive under water, and then the effect of purging rubber powder can be improved.
In order to linking wind-guiding is better achieved, convergence hole 101a extends along the direction of the outlet side of insufflation channel 100b.Tool
Body, convergence hole 101a is that the cross-sectional area at uiform section hole, i.e. convergence hole 101a each position in the direction of the air flow is equal.
As described above, during die sinking, oblique top 101 is in the presence of jacking mechanism 100f by jack-up, convergence hole
101a is connected with diving under water with the ejection connection insufflation channel 100b of oblique top 101 into cast gate 100a.In order that obtaining the process in die sinking
Middle convergence hole 101a connects insufflation channel 100b and dives under water into cast gate 100a quickly, shortens the motion row of jacking mechanism 100f
Journey, it is preferred that convergence hole 101a is located at one end near liftout face in oblique top 101, and so-called liftout face refers to oblique top 101 and uses
In the surface of jack-up plastic cement products 30.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent, improvement etc., should be included within the protection domain of the application.
