Abstract

The die equipment comprises a male die and a female die which are respectively equipped with die cavities allowing upper water level inner die rod and low water level die cup to pass in and out. The die rod can be gone deep into the inner hole of the die cup, and positioned on its bottom end surface. The die cup can be stopped by means of stopping edge of the low water level die cavity. USE/ADVANTAGE-the die equipment is used for production of plastic pipe joint; the diameter of its water outlet end is less than that of inner section pipe and inlet end, and the outlet end can be used for OD plug-in connection of pipes.

Description

Plastic adaptor and mould thereof

The present invention relates to a kind of plastic adaptor and mould thereof, particularly be used to provide the water pipe grafting and use.

The shaping die and the product of known plastic cement pipe tee union, as shown in Figure 1, 2, 3, the interior tringle B of this shaping die A for stretching into by three-dimensional respectively, make each mouth of pipe of tee union C form the finished product of mouth of pipe end face diameter greater than inner segment, but pegged graft by each mouth of pipe water pipe, the known tee union of this kind in use, occupy the engagement positio of water level lower end, will cause the joint compound viscosity of engagement positio inharmonious because of the long-term impact of water liquid, have water liquid leakage problems.So, building is had harmful effect, make wallpaper, the peeling paint of wall.

The object of the present invention is to provide a kind of mould of plastic adaptor and the plastic adaptor of production thereof, after the liquid delivery line that can supply water engaged, the two warp used for a long time, did not still have leakage problems.

Mould of the present invention respectively is provided with die cavity with male model, master mold, itself and fashionablely keep supplying tringle in the water level, water level mould cup is deeply or withdraw from down, the following water level die cavity of this male and female mould has stop edge can supply down, and water level mould cup apical grafting stops, this time water level mould cup has endoporus, can keep supplying the interior tringle of water level deeply, and go up the endoporus bottom end that the interior tringle terminal of water level can withstand on down water level mould cup; Utilize the outlet end of the cup-shaped one-tenth of water level mould down, its external diameter is little than the external diameter of entry end and inner segment pipe, so the water pipe of joint entry end is to be connected with interpolation method, the water pipe of outlet end then can extrapolation mode be connected, therefore, the water liquid of deriving via outlet end can not impact being connected wall, and then this bond effect that is connected wall is preferable, does not have water liquid leakage problems.

Now with an embodiment, and conjunction with figs. describes structure of the present invention, feature in detail.

Fig. 1 is a part sectioned view of commonly using mould.

Fig. 2 is a sectional drawing of commonly using plastic adaptor.

Fig. 3 is an enforcement illustration of commonly using plastic adaptor.

Fig. 4 is the three-dimensional exploded view of mould of the present invention.

The part sectioned view of Fig. 5 during for die assembly of the present invention.

Fig. 6 is the sectional drawing of plastic adaptor of the present invention.

Fig. 7 is the enforcement illustration of plastic adaptor of the present invention.

See also shown in Figure 4ly, mould of the present invention includes master mold 1, male model 2, goes up tringle 3 in the water level, members such as water level mould cup 4 down.

This master mold 1 is provided with die cavity 11, can form the profile of most of finished product, this die cavity 11 is according to the needs on using, can be two logical, threeways, it includes the water level die cavity and reaches water level die cavity down, and this die cavity and side connect, keep supplying with water level die cavity on this that tringle 3 stretches in water level, this time water level die cavity then can insert for following water level mould cup 4, and this time water level die cavity has a stop edge 12, can contact with it during water level mould cup 4 insertions instantly to stop; This master mold 1 itself is provided with post hole 13 again, can insert for the post 23 of male model 2, forms the correct closure of male and female mould; For the plastics system of penetrating is necessary, this master mold 1 is provided with material shooting hole 14, makes plastics can be incident upon die cavity 11.

This male model 2 has the die cavity 21 that the die cavity 11 with master mold 1 matches, and the die cavity 11 of this die cavity 21 and master mold 1 respectively be half of the most of profile of finished product, and with stop edge 22, contacts with it during for water level mould cup 4 insertions down to stop; This male model 2 is provided with post 23, can be inserted in the post hole 13 of master mold 1, makes male and female mould closure correctly.

Should go up in the water level tringle 3 according to the necessity on making, and be set on each in the water level die cavity, it can be more than one; Upward water level tringle 3 can rest in the die cavity 11 or leave this die cavity fully, makes the plastic and taking-up of finished product; Should go up power modes such as the interior tringle 3 usable oils cylinder pressures of water level, do automatic expanding-contracting action.

Following water level mould cup 4 can be embedded in the die cavity 11, and contacts with stop edge 12,22, and will descend the water level die cavity all to fill up; This time water level mould cup 4 is provided with endoporus 41, and the diameter of endoporus 41 is the following water level external diameter of finished product, and endoporus 41 can be for water level tringle on corresponding with it one 3 deeply, and the terminal that should go up tringle 3 in the water level closely is connected to endoporus 41 bottom ends; This time water level mould cup 4 can oil hydraulic cylinder etc. motivational drive, it entered or leave die cavity 11,21.

See also the situation of male and female mould closure of the present invention shown in Figure 5, at this moment, tringle 3, following water level mould cup 4 rest in the closed die cavity 11,21 in the last water level, and the terminal apical grafting of tringle 3 is at endoporus 41 bottom ends of following water level mould cup 4 in the last water level, therefore, it is launched into the joint body 5 that can form behind the plastics as shown in Figure 6.

As seen from Figure 7, joint body 5 is provided with entry end 51 and outlet end 52, the extended formation of the bore of this entry end 51 is than major diameter, the then reduced one-tenth of outlet end 52 is than minor diameter, internal diameter by entry end 51 can be pegged graft for pipe 6, and to do infeeding of water liquid, outlet end 52 is then pegged graft for the inwall of pipe 6 by external diameter, and this grafting surface of contact can be coated with sticking with adhesive, makes the two that good joint be arranged.

Claims

1, a kind of plastic adaptor mould, it includes male model, master mold, upward the interior tringle of water level reaches water level mould cup down; This male model, master mold respectively are provided with die cavity, it is deep and withdraw to keep supplying in the water level tringle and following water level mould cup by the die cavity of closure, it is characterized in that: the following water level die cavity of this male model, master mold is provided with stop edge, when being goed deep into, water level mould cup can become apical grafting to stop, this time water level mould cup has endoporus, its aperture is the external diameter of water level pipe under the plastic adaptor, and this endoporus can be for tringle in the water level on corresponding with it deeply, and should go up the endoporus bottom end that tringle terminal in the water level withstands on down water level mould cup.
