Receiving space.On the one hand, the mould of said structure causes the first inserts 221 and the second inserts 222 to be easier to insert the 3rd installation
The mounting groove 112 of groove 111 and the 4th；On the other hand, in matched moulds, the mould of said structure enables to the first inserts 221 firm
Ground is fixed on first receiving space, the second inserts 222 is firmly secured to the second receiving space, the first inserts when avoiding matched moulds
221 and second inserts 222 move and influence Product processing, meanwhile, it also avoid SMC resin penetrations under high temperature to inserts component
Gap between 22 and cover half 21 or dynamic model 11 and when inserts component 22 is stuck, is not easy the phenomenon that ejects.
It should be understood that being additionally provided with the first through hole (not indicating) connected with the first mounting groove 211 on cover half 21 and with
The second through hole (not indicating) of two mounting grooves 212 connection, the first thimble 231 can pass through first through hole and extend to the first installation
The thimble 231 of groove 211 or first can pass through the second through hole and extend to the second mounting groove 212, so that the first thimble 231 can push up
Go out inserts component 22.The third through-hole connected with product die cavity 30 is additionally provided with cover half 21, the second thimble 232 can pass through the 3rd
Through hole and extend to product die cavity 30 so that the second thimble 232 being capable of ejecting product 40.
The present invention also provides a kind of mould pressing method of SMC molded products, comprises the following steps：
S01：SMC sheet material is cut
Specifically, SMC sheet material is cut using cutting machine according to the shapes and sizes of product and mould.
S02：SMC sheet material after cutting is molded using mould
Mould includes dynamic model mechanism 10 and fixed die mechanism 20, and fixed die mechanism 20 includes cover half 21, inserts component 22 and ejection
Component 23, dynamic model mechanism 10 include dynamic model 11, and dynamic model 11, cover half 21 and inserts component 22 cooperatively form product die cavity 30；Ejection
Component 23 is flexibly connected with cover half 21 for product 40 and inserts component 22 to be ejected.Inserts component 22 includes interval and set relatively
The first inserts 221 and the second inserts 222 put, cover half 21 are provided with the first mounting groove 211 and the second mounting groove 212.First is embedding
Part 221 is provided with the first convex portion 2211, and the first convex portion 2211 is extended towards product die cavity 30；Second inserts 222 is provided with
Second convex portion 2221, the second convex portion 2221 are extended towards product die cavity 30.
First, the SMC sheet material after part is cut is assembled with inserts component 22, then after being assembled with part cutting
The inserts component 22 of SMC sheet material be installed on cover half 21.Specifically, the SMC sheet material after part is cut carries out perforate.According to
The SMC sheet material that is actually needed after the perforate for selecting suitable quantity is simultaneously laid on the first inserts 221, position of opening and
The correspondence of one convex portion 2211；At the same time, according to being actually needed the SMC sheet material after the perforate for selecting suitable quantity and laid
On the second inserts 222, wherein the position of perforate is corresponding with the second convex portion 2221, completes the SMC sheet material after cutting respectively with the
The assembling of one inserts 221 and the second inserts 222.
Secondly, the first inserts 221 of the SMC sheet material being assembled with after cutting is installed on the first mounting groove 211, assembling
The second inserts 222 for having the SMC sheet material after the cutting of part is installed on the second mounting groove 212.SMC after remainder is cut
Sheet stock is put into product die cavity 30, according to shape of product, the SMC after cutting is put the larger location-appropriate of product thickness or width more
Sheet stock.
Finally, dynamic model 11 and the matched moulds of cover half 21 are subjected to compression molding to the SMC sheet material after cutting.Wherein, compression molding
Process conditions it is as follows：Pressing time is 15-20s, dwell pressure 8-12MPa, dwell time 180-300s, and dynamic model 11 is warm
Spend for 130-160 DEG C, the temperature of cover half 21 is 130-160 DEG C.After molding terminates, dynamic model 11 and cover half 21 are molded into taking-up product
40。
The mould pressing method of above-mentioned SMC molded products by by part cut after SMC sheet material respectively with the first inserts 221 and
Second inserts 222 is assembled, and then will be assembled with the first inserts 221 and the second inserts 222 of the SMC sheet material after part is cut
It is respectively arranged on the first mounting groove 211 and the second mounting groove 212；SMC sheet material after remainder is cut is put into product mould
Chamber 30, thus before compression molding, this method can be such that each corner of product die cavity is filled with and product die cavity SMC sheet
Material, and the SMC sheet thickness being adapted with the opening position shape is laid on product die cavity diverse location, thus this method can
The product of manufacturing complex shapes, the filling after compression molding at the corner of product or corner is uniform, avoids because filling is uneven
And the problem of causing product cracking, insufficient strength.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
