Specific embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
A preferred embodiment of injection mold 100 of the present invention is shown also referring to Fig. 2 to Fig. 6.The injection mold
100 to be molded plastic cement products 900 as shown in Figure 1, and includes the cover half 1 and dynamic model 2 of mutual cooperation.
Fig. 4 and Fig. 5 are referred to, and with reference to shown in Fig. 1, the cover half 1 includes cover half die holder 11, is equipped with cover half mould
Sliding block 12 and cover half die 13 on seat 11.
Wherein, in the cover half die holder 11 formed with the die cavity 111 to forming plastic cement product 900, be formed at die cavity 111
The chute 112 of surrounding.The chute 112 is opened towards die cavity 111 and the direction of dynamic model 2 and set, and towards the one of die cavity 111
First internal face 1121 of the side formed with outward-dipping extension.In the present embodiment, the chute 112 was in the die cavity 111 weeks
Enclose formed with three, three sliding blocks 12 are housed with corresponding.
The die cavity 111 is formed between sliding block 12.For the corresponding spaced protrusions for being molded the outside of plastic cement products 900
901, the inner side of sliding block 12 is provided with corresponding groove 121.The groove 121 is formed as a part for die cavity 111, with altogether
With the shaping plastic cement products 900.
Refering to Fig. 3, Fig. 6 and with reference to shown in Fig. 1, the dynamic model 2 includes dynamic model die holder 21, protruded into the die cavity 111
Core 22, the buckling structure 23 that is engaged with one end of sliding block 12 towards dynamic model 2 and to eject the top of plastic cement products 900
Go out structure 24.The buckling structure 23 and sliding block 12 are coordinated using inclined-plane, to be moved in the dynamic model 2 towards away from the direction of cover half 1
When, the buckling structure 23 towards the remote direction of cover half 1 and is displaced outwardly with movable slider 12 while in the chute 112.
Specifically, with reference to shown in Fig. 4 to Fig. 6, the sliding block 12 has the main part 122 being engaged with the chute 112
Be connected to coordinating block 123 of the main part 122 towards the one end of dynamic model 2.
The coordinating block 123 has the connecting portion 1231 that opening position of the bottom of main body 122 close to outside extends vertically
With the auxiliary section 1232 that extension is laterally inward from connecting portion 1231.The auxiliary section 1232 is towards a side surface of main part 122
Extension is tilted, that is, the mating surface 1233 for tilting extension is formed, to be engaged with buckling structure 23.The mating surface 1233 is from cover half
1 slopes inwardly towards the direction of dynamic model 2 extends, when being moved with causing buckling structure 23 to drag sliding block 12, the power that puts on sliding block 12
Can be analyzed to the pulling force to the direction of dynamic model 2 and outside power so that the sliding block 12 can simultaneously towards the direction of dynamic model 2 and outwards
It is mobile, and then the plastic cement products 900 gradually with shaping in the moving process of sliding block 12 are separated, to facilitate plastic cement products 900 de-
Mould.
The outward-dipping extension of the outside wall surface of main part 122 of the sliding block 12, and be engaged with first internal face 1121,
When dynamic model 2 moves with movable slider 12, to make the sliding block 12 be moved along first internal face 1121.The shape of groove 121
Into in the inner side of the main part 122.
Further, chute 112 described in the present embodiment and the both sides of sliding block 12 are provided with the guiding knot being mutually slidably matched
Structure 13.The 13 outward-dipping extension of guiding structural, during further ensureing that the dynamic model 2 moves with movable slider 12, sliding block 12
While towards the remote direction of cover half 1 and it is displaced outwardly in the chute 112.
Specifically, as shown in Figure 4 and Figure 5, in the both sides of chute 112, the adjacent opening position of first internal face 1121 difference is recessed
Provided with a guide channel 1121, the both sides of sliding block 12 are provided with the director strip 1221 being slidably matched with the guide channel 1121.It is described
Guide channel 1121 and director strip 1221 form the guiding structural 13.
In the present invention, the buckling structure 23 on the dynamic model 2 is the clasp block that is fixed on the dynamic model die holder 21, institute
State in clasp block formed with housing the accepting groove 231 of the auxiliary section 1232.
Refering to shown in Fig. 3, Fig. 6, the ejecting structure 24 is disposed adjacent with the core 22, to cause in plastic cement products
After 900 shapings, the ejecting structure 24 is held in the bottom of the plastic cement products 900, and then conveniently by the autotype of plastic cement products 900
Ejected on core 22.
As known from the above, it is of the invention by setting chute 112 and the structure of sliding block 12 around the die cavity 111 on cover half 1, and
So that when dynamic model 2 is towards away from the movement of the direction of cover half 1, the buckling structure 23 set on dynamic model 2 can exist simultaneously with movable slider 12
Towards away from the direction of cover half 1 and being displaced outwardly in chute 112；Thus, there is level side in the outside of plastic cement products 900 for needing to be molded
, can be by setting corresponding structure to can be achieved on sliding block 12 when upward groove or raised structures；This kind injection of the invention
The implementation overall structure of mould 100 is simple, and plastic cement production can be progressively disengaged when sliding block 12 drives mobile by dynamic model 2
Product 900, are convenient in demoulding.
The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent substitution, without departing from the spirit and scope of technical solution of the present invention.
