The specific embodiment
Below by Fig. 1 to Fig. 4 one embodiment of the present of invention are described.
Fig. 1 is an example of dust catcher rotating brush axis body 1 for the formed products that is shaped with ester moulding mould of the present invention.On the outer circumference portion of drum shape formed products, be provided with torsional direction different helical form slot part 2a, 2b.
Fig. 2 to Fig. 4 represents to be used to form the ester moulding mould of the dust catcher rotating brush axis body among Fig. 1.1a is the formed products of the die cavity side of dust catcher rotating brush axis body 1, and 1b is the formed products of the core side of dust catcher rotating brush axis body 1.3 is die cavity, and 4 is core rod, and 5 is the die cavity insert, and 6 is the core rod insert, and 7 is the rotary body that die cavity insert 5 and core rod insert 6 are rotated on direction of rotation.8 is cast gate, and 9a is a die cavity side fixed bar, and 9b is the core side fixed bar.10 is oil hydraulic cylinder, and it and core rod 4 connect, and core rod 4 can be opened can be closed, and mould is opened or closure.At this moment, die cavity 3 is the state of being fixed, and cannot move.11 is ejection pieces, and it ejects the formed products 1b of core side under the promotion of liftout tank 12, make it depanning.13 is the inclined plane jut, and 14 are the inclination slot part.Inclined plane jut 13 and inclination slot part 14 are adjusted chimeric mutually on the position that helical form slot part 2a, the 2b that can make dust catcher rotating brush axis body 1 on the interface of mould aim at automatically.
Be described in detail in the forming process of carrying out in the mould with above-mentioned formation below.
From the resin of cast gate 8 through die cavity insert 5 after core rod insert 6 is filled, oil hydraulic cylinder 10 is opened core rod 4.At this moment, because core rod 4 moves under the state of the formed products 1b that is keeping core side, die cavity insert 5 recently rotates in the spiral helicine pitch of the helical form slot part 2a that forms on according to the surface at the formed products 1a of die cavity side under the effect of rotary body 7, makes die cavity side shaping thing 1a break away from the mould (see figure 3).
Then, the ejection piece 11 that is located at core rod 4 sides is promoted by liftout tank 12, the formed products 1b of top upper mold core side, thus make core rod insert 6 and die cavity insert 5 the same rotating, make the formed products 1b of core side break away from the mould (see figure 4).
In addition, core rod 4 and die cavity 3 are equivalent to formed products is remained on the rotation holding member of non-rotating state.
In addition, can also comprise control, make after either party's the insert rotation, make the opposing party's insert rotation, the control part that mould is opened from the interface of insert.
In addition, in above-mentioned shaping flow process, die cavity insert 5 and core rod insert 6 are to open mould by rotating on spiral helicine circumferencial direction respectively from the interface of insert, but also can open mould like this: make either party's insert rotation, after breaking away from mould, under the effect of the formed products rotating part that formed products is being rotated on the spiral helicine circumferencial direction, allow formed products rotate, thereby break away from mould.
The effect of above-mentioned formation is as follows:
Owing to be to allow the spiral-shaped pitch ratio of slot part 2a, 2b that die cavity insert 5 and core rod insert 6 form according to the surface at dust catcher rotating brush axis body 1 separately rotate in a circumferential direction when opening mould, and dust catcher rotating brush axis body 1 is rotated, so can use small-sized simple mold structure to have the dust catcher rotating brush axis body 1 of helical form slot part, and precision is expensive low by ester moulding production.Can also suppress simultaneously dust catcher rotating brush axis body 1 phenomenons such as warpage take place, not have the bad forming process of the mould of disengaging.
In addition, owing to be to allow the pitch ratio of the helical form slot part that either party in die cavity insert 5 and the core rod insert 6 forms according to the surface at dust catcher rotating brush axis body 1 rotate in a circumferential direction earlier when breaking away from mould, make dust catcher rotating brush axis body 1 open mould, break away from mould thereby allow formed products on spiral helicine circumferencial direction, rotate again, so can use small-sized simple mold structure to have the dust catcher rotating brush axis body 1 of helical form slot part by ester moulding production, and the precision height, low cost of manufacture.
In addition, above-mentioned jut 13 and above-mentioned slot part 14 are chimeric mutually on the position that helical form slot part 2a, the 2b that can make formed products on the above-mentioned interface are aiming at, so helical form slot part 2a, the 2b position alignment on the interface of die cavity insert 5 and core rod insert 6 of formed products can automatically be adjusted.
Also have, cast gate 8 is positioned at the end face of formed products, and is divided into a plurality of osculums in the place near formed products, and shaping operation can be undertaken by the 2c among Fig. 1,2d such 2 places or the cast gate more than 2 places.So resin be not resemble when having only a cast gate towards Cylindorical rod a direction one-way flow, but flow equably around Cylindorical rod, can carry out good filling to mould, thereby can suppress dust catcher rotating brush axis body 1 warpage, improve dimensional accuracy and presentation quality.
In addition, owing to resin flows into from end face, thus when containing the resin material of glass, use can make the orientation unanimity of glass fibre, thus material is flowed easily, can also improve the rigidity of formed products.
In addition, injecting air at the gap of Fig. 2 A7a, B7b can cool off the rotary body 7 that die cavity insert 5 and core rod insert 6 are rotated on direction of rotation, stuck to prevent rotary body 7 because of heating, it can be rotated smoothly, thereby make the forming quality of formed products stable, also can improve the endurance life of mould.
