Description
Technical field
The utility model relates to foaming mould technical fields, more particularly, to the exhaust casing shaping mould in a kind of engine bin.
Background technique
The mold of foaming is exactly plastic foaming mould.Foaminess resin is directly inserted in mold, it is heated
Melt, form gas-liquid saturated solution, by nucleation, form a large amount of small complexs, complex increases, and foam plastic is made.
It is as shown in Figure 1 the exhaust cylinder structure in a engine bin, is equipped at the exhaust casing outer surface both sides of the edge recessed
Region is fallen into, is equipped with several " U "-shaped protrusions 111 in sunk area, but since the exhaust casing side wall is very thick, by common
Injection mold cannot achieve the molding of the exhaust casing, design a foaming mould now to form the exhaust casing.
Summary of the invention
The technical problem to be solved by the utility model is to provide the exhaust casing molding dies in a kind of engine bin, are intended to lead to
The mold is crossed to form exhaust casing.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of exhaust casing in engine bin at
Pattern, including upper die and lower die, the upper mold bottom are equipped with the punch-pin for forming product inner surface, and the punch-pin is equipped with square
Shape slot is equipped with mold insert in the rectangular channel, is equipped with the cavity plate for forming product external surfaces, the punch-pin at the top of the lower die
It is adapted with cavity plate, the punch-pin and cavity plate molding constitute product die cavity, and the punch-pin is additionally provided with inner cavity, the inner cavity
In be equipped with heat generating component, the heat generating component can heat punch-pin, and the upper mold is equipped with the material path communicated with punch-pin,
It is equipped with the first recess and the second recess in the cavity plate, is equipped with third between first recess and the second recess and is recessed,
Character code is carved on the third recess and mold insert surface, is equipped at predetermined intervals in first recess several " U "-shaped
The first recess portion, be equipped with several the second " U "-shaped recess portions at predetermined intervals in described second recess.
It is further improved as the utility model, first recess and the second recess are symmetrical about third recess, institute
It is several first recess portions stated and several second recess portion profiles, in the same size.So that the product surface molded is beautiful.
It is further improved as the utility model, indent form, the edge is presented in the character code in the third recess
Evagination form is presented in character code on part.
Compared with prior art, the utility model has the advantage of simple structure and reasonable designs, by connecting with foaming machine
It connects, exhaust casing is molded in the utility model.In simple terms, the utility model is installed in foaming machine carry out using,
Upper mold and lower die are molded, feed liquid flows into die cavity by material path, is heated by heat generating component to punch-pin, and then to product mould
Chamber because heating temperature increases, be heated the foaming in product die cavity by feed liquid.The word being carved in mold insert and the third recess of setting
Code can print off character code on product after shaping, and respectively arranged several first recess portions in the first recess, the second recess,
Second recess portion is the protrusion in order to mold " u "-shaped in product.
Detailed description of the invention
Fig. 1 is exhaust casing structural schematic diagram；
Fig. 2 is the utility model part-structure decomposition diagram；
Fig. 3 is upper die structure schematic diagram.
