Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further below with reference to examples and drawings
Bright, the content that embodiment refers to not is limitation of the invention.
Please refer to Fig. 1 to Fig. 6, a kind of injection mold of car trim of the invention, including top clamping plate 1, be set to it is fixed
Cover half component 2, Bottom clamp plate 3 and the dynamic model component 4 set on Bottom clamp plate 3 of die holder plate 1, the cover half component 2 include cover half
Plate 21, the first mold core 22 and the second mold core 23；
The solid plate 21 is equipped with the first type chamber 211, and first mold core 22 is in the first type chamber 211；
First mold core 22 is equipped with second type chamber 221, and second mold core 23 is in second type chamber 221；
Second mold core 23 is equipped with the cavity 231 through upper and lower end face, the side wall and second type of second mold core 23
The wall body of chamber 221 is bonded.
Specifically, workpiece 100 is the car trim for needing to process in the present embodiment, 100 one end of workpiece is in curved surface
It is larger in the specification of short transverse to lead to workpiece 100 for shape, therefore in the mold manufacturing process, needs large volume of
Mold core can meet manufacturing condition, and mold core is divided into two parts, the first mold core 22 and second by the injection mold of the car trim
Mold core 23, wherein the first mold core 22 is in the first type chamber 211 of solid plate 21, the second mold core 23 embedded in the first mold core 22 the
In two type chambers 221, the processing respectively of mold core is realized in the setting of two mold cores, i.e. the first mold core 22 and the second mold core 23 can be simultaneously
The processing of the processes such as wire cutting, polishing, polishing is carried out, while also realizing the effect for reducing production material cost, because of second
The small volume of mold core 23 can choose suitable processing clout and be processed, improves the utilization rate of mold core consumptive material.
By the way that mold core is divided into two parts, realizes and the manufacturing procedures such as wire cutting, polishing, polishing are carried out to two mold cores simultaneously
Production, improve production efficiency, select suitable processing clout to process the second mold core, improve the utilization rate of mold core consumptive material, meet
It improves production efficiency and reduces the requirement of production cost.
Second mold core 23 includes the first mold insert 2301, the second mold insert 2302 and several third mold inserts 2303, described
Third mold insert 2303 is set between the first mold insert 2301 and the second mold insert 2302.
First mold insert 2301 and the second mold insert 2302 are U-shaped, and the third mold insert 2303 is in a strip shape.
The quantity of first mold insert 2301 is one, U-shaped, and the quantity of the second mold insert 2302 is one, U-shaped, third edge
The quantity of part 2303 is two, and in a strip shape, the first mold insert 2301, the second mold insert 2302 and third mold insert 2303 enclose and set to form openning
Shape forms the second mold core 23, and in whole set of die, the material cost of different components is different, especially the monovalent cost of core material
Second mold core 23 is divided into several segments by highest, according to mold core clout size, design volume mold insert of different sizes：First mold insert
2301, the second mold insert 2302 and third mold insert 2303 further increase the utilization rate of mold core consumptive material, realize mold core consumptive material utilization rate
Maximization, meanwhile, three different mold insert the first mold inserts 2301, the second mold insert 2302 and third mold insert 2303 can add simultaneously
Work further shortens process time.
First mold insert 2301 is greater than the second mold insert 2302 embedded in 221 depth of second type chamber and is embedded in second type chamber 221 deeply
Degree；
The third mold insert 2303 is deep embedded in second type chamber 221 less than the first mold insert 2301 embedded in 221 depth of second type chamber
Degree, the third mold insert 2303 are more than or equal to the second mold insert 2302 embedded in 221 depth of second type chamber and are embedded in second type chamber 221 deeply
Degree.
Second mold core 23 is divided into three parts by the characteristics of for 100 vertical height direction of workpiece：First mold insert 2301,
Three mold inserts 2303 and the second mold insert 2302, wherein the height specification of the first mold insert 2301 is greater than the high metric of third mold insert 2303
Lattice, the height specification of third mold insert 2303 are more than or equal to the height specification of the second mold insert 2302, realize each position processing of mold core
Flexibility, meet the different of 100 different parts of workpiece and require, mold core is split, the difficulty of processing of mold core is reduced.
First mold insert 2301 is interference fitted with third mold insert 2303, second mold insert 2302 and third mold insert 2303
Interference fit, avoids generating gap between mold insert, sizing material flows into gap, influences the qualification rate of workpiece 100.
The upper surface of second mold core 23 protrudes from the upper surface of the first mold core 22, the upper surface of first mold core 22
Protrude from the upper surface of solid plate 21.
The dynamic model component 4 includes moving template 41 and third mold core 42, and the moving template 41 is equipped with third type chamber 411, institute
Third mold core 42 is stated embedded in third type chamber 411 and is connect with moving template 41.
The surface of the third mold core 42 is lower than the surface of moving template 41, the surface of first mold core 22 and third mold core
42 surface fitting, second mold core 23 are located in third type chamber 411.
When the cover half component 2 is pressed with dynamic model component 4, the first mold core 22 formed after being closed with third mold core 42 at
Pattern chamber, the upper surface of the prominent solid plate 21 of the first mold core 22, a part of the first mold core 22 is in third type chamber 411, no
The generation of inconsistent phenomenon when the first mold core 22 only being avoided to be combined with third mold core 42, while outside air being avoided to pass through moving template 41
Gap between solid plate 21 enters shaping mold cavity, to realize the purpose for improving 100 qualification rate of workpiece.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
