Example (b):

as shown in figures 1 to 9: (fig. 9 shows a child seat upper shell product L referred to in the present design, and hereinafter collectively referred to as a product).

The utility model provides a mould of preparation automobile-used children's seat epitheca, including last mould 1, lower mould 2, top hole mechanism 3, last die cavity 101 has been seted up to the bottom of going up mould 1, lower die cavity 201 has been seted up to the bottom of lower mould 2, it drops on the top of lower mould 2 (this is the butt joint mode of two mould about general, do not describe here in addition) to go up mould 1 through the mould guide pillar, as shown in fig. 2, fig. 3, the left side of lower die cavity 201 is provided with side die cavity 202, side die cavity 202 communicates with lower die cavity 201 and has constituted L formation die cavity jointly, as shown in fig. 4, fig. 5 and fig. 6, top hole mechanism 3 installs on the template, this top hole mechanism 3 is the core structure of this design, the front side of lower mould 2 is opened and is equipped with mounting groove 203, top hole mechanism 3 is located the mounting groove 203, open between mounting groove 203 and the side die cavity 202 has guiding hole 204, hydro;

the hole ejecting mechanism 3 includes two side inserts 301 installed on a bottom plate through bolts, a hole die 303 slidably fitted between the two side inserts 301 through slide rails, a push block 302 slidably fitted to an outer end of the hole die 303 through slide rails, and a connection groove 304 provided at a front end of the push block 302, wherein the connection groove 304 is a vertical T-shaped handle, an inner end of an actuating rod of the oil cylinder 4 is provided with a clamping groove, and the oil cylinder 4 is clamped in the connection groove 304 through the clamping groove, so that when the oil cylinder 4 acts, the actuating rod at the inner end thereof pushes the push block 302 to move inwards, and the hole die 303 slidably fitted with the push block 302 is urged to move towards the left, and the final purpose is to cause a left end die section of the hole die 303 to enter the side die cavity 202.

Specifically, the method comprises the following steps: in order to improve the structural reasonableness, the hole die 303 which is moved once can be reset again, as shown in fig. 6 and 7, two spring guide holes 305 are formed in the top of the left end of the hole die 303, a front reset spring 5 and a rear reset spring 5 are installed on the rear groove wall of the installation groove 203 in a mode of forming the installation holes, the outer ends of the reset springs 5 enter the spring guide holes 305, the hole die 303 penetrates through the guide holes 204 and enters the left side to press the structural hole L1 of the product L, when the oil cylinder 4 actuating rod pulls the push block 302 to move outwards, the reset springs 5 push the hole die 303 to reset from left to right, and the round platform-shaped structural section on the left side of the hole die 303 retracts into the guide holes 204 to reset, and the structural design is reasonable.

The working principle is as follows: the mold is installed on an injection molding machine, plastic liquid is injected from a pouring hole of an upper mold 1 and enters an injection molding cavity formed between an upper mold cavity 101 and a lower mold cavity 201, a product L shown in FIG. 9 is injected, at this time, an oil cylinder 4 acts and pushes a push block 302 to move inwards by using an action rod at the inner end of the oil cylinder, and as the left end surface of the push block 302 is designed to be inclined and the right end surface of a hole mold 303 is designed to be inclined as shown in FIGS. 6 and 8, the push block 302 is extruded onto the inclined surface of the hole mold 303 by using the inclined surface thereof when moving inwards, so that the hole mold 303 is forced to move towards the left, at the same time, as the left end of the hole mold 303 is in a truncated cone structure and is positioned in a guide hole 204, so that the left end truncated cone of the hole mold 303 moving towards the left enters the guide hole 204 and then enters a side mold cavity 202, at this time, a molding cavity for injection molding the product L shown in FIG. 9 is formed as the upper mold cavity 101 and the lower mold cavity, therefore, the injection solution entering the forming cavity will form the product L as shown in fig. 9, and the hole mold 303 moving towards the left can press the product L towards the left to press the structure hole L1 at the bottom section of the product L, as can be seen from fig. 9, the product L to be formed by the present design is a special-shaped product, and one side of the product L is provided with a forming section extending downwards, and a structure hole with a relatively complex structure needs to be pressed at the bottom of the forming section, so that it is difficult for a general mold to form the structure hole L1 in the injection molding process of the product L, and the present design can see that the top hole mechanism 3 is added to complete the working process in the above manner, and because the product L is already compressed and does not act when the upper mold 1 and the lower mold 2 are combined to inject the product L, the top hole mechanism 3 acting in the process of pressing the structure hole L1 at the bottom of the longer section of the product, the hole pressing position is accurate, the injection molding piece cannot deform when the hole is pressed, the injection molding upper shell piece does not need to be moved out of the mold cavity, and then the hole is formed by drilling equipment, so that the working efficiency is improved.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
