Drawings

The utility model is described in further detail below with reference to the following figures and embodiments:

FIG. 1 is a schematic structural view of a core-pulling plastic mold for a composite angle slide block according to the present invention;

FIG. 2 is a schematic view of the plastic mold in a closed state;

FIG. 3 is a schematic view of the plastic mold in an open state;

FIG. 4 is a schematic view of the movement of the parts of the plastic mold in the mold-opened state.

Detailed Description

For example, as shown in fig. 1, the plastic mold for core pulling of the compound angle slide block of the present invention comprises a slide block insert 2, an inclined guide post 3, a press block 4, a slide block seat 5 and a guide block 6, wherein the inclined guide post 3 is fixed on a fixed mold plate of the mold, the press block 4 and the guide block 6 are fixed on a movable mold plate of the mold, the slide block seat 5 is provided with an inclined hole 51 and a T-shaped groove 52 on a front side surface, the inclined guide post 3 is arranged in the inclined hole 51 of the slide block seat 5, the press block 4 is located on two sides of the slide block seat 5, a top 21 of the slide block insert 2 for pushing a plastic part 1 is provided on a front end surface, a first T-shaped slide rail 22 is provided on a rear end surface, a second T-shaped slide rail 23 is provided on a bottom surface, the first T-shaped slide rail 22 on the rear end surface of the slide block insert 2 is provided in the T-shaped groove 52 on the front side surface of the slide block seat 5, a top surface of the guide block 6 is an inclined surface matching with the bottom surface of the slide block insert 2 and is provided with a T-shaped groove 61, the second T-shaped slide rail 23 on the bottom surface of the slide insert 2 is arranged in the T-shaped groove 61 on the top surface of the guide block 6.

Preferably, steps 53 are arranged on two sides of the slider seat 5, and the pressing block 4 is arranged on the steps 53 on two sides of the slider seat 5.

Preferably, the top 21 of the front end surface of the slide insert 2 is a spherical head.

After the mold is installed into an injection molding machine, the mold closing state is shown in figure 2; after completing one injection molding operation, the mold opened state is shown in fig. 3. After the injection molding is finished, the moving direction of the core-pulling structure of the composite angle sliding block of the mold is shown in fig. 4. Under the action of the mold opening force of the mold, the fixed mold plate pulls the inclined guide post to move upwards, at the moment, under the action of the inclined guide post, the slider seat and the inclined guide post also move along the same direction, but the slider seat is limited to move upwards due to the fixation of the pressing block, so the slider seat finally slides towards the right direction; the slider seat is connected with the slider insert through a T-shaped structure, the slider seat slides to the right and simultaneously drives the slider insert to move together, and after the guide block is arranged at the bottom of the slider insert, the slider insert finally moves to the right and downwards under the limitation of the guide block. Thereby fixing the moving direction of the slide block insert and ensuring that the slide block insert does not damage the structural characteristics of the plastic part during core pulling. As shown in fig. 1, the end of the plastic part 1 is provided with arc-shaped features 11 protruding from both sides, the arc-shaped features 11 form an included angle greater than 0 ° and smaller than 90 ° with the horizontal direction, if the slide insert moves horizontally, the arc-shaped features 11 form an inverted state with respect to the horizontal direction, and if the slide insert continues to move horizontally, the arc-shaped features 11 are damaged, so that the slide insert moves obliquely through the structural design of the mold, and the damage of the plastic part features is avoided.

The mould solves the technical problems that the mould cannot be demoulded in a single core-pulling direction, and the structural characteristics of the plastic part can be ensured to be complete only by pulling cores in a multi-angle direction in a three-dimensional space. The mould has the advantages that the action in two or more than two core-pulling movement directions is completed once in the process of one-time mould opening action, so that the plastic part can be smoothly demoulded from the mould.
