Problems solved by technology

In this way, both sets of core-pulling mechanisms are installed in the mold, which has a complex structure and takes up a lot of space, resulting in an increase in the size of the mold base, an increase in the cost of mold manufacturing, and the core-pulling process is complicated, and there are errors in the cooperation between parts. Low molding quality

[0029] Please refer to figure 1 , figure 2 , image 3 and Figure 4 , the embodiment of the present invention provides a combined core-pulling mechanism 100 for core-pulling molding of products. It can complete core-pulling actions in two different directions at the same time, simplify the core-pulling structure, reduce occupied space, reduce mold manufacturing costs, and make the core-pulling process stable and reliable, ensuring product molding quality. In this embodiment, the combined core-pulling mechanism 100 is used for core-pulling a product containing buckles and ribs at the same time, wherein the core-pulling direction of the buckle and the core-pulling direction of the ribs are perpendicular to each other, and the combined core-pulling mechanism 100 can Core-pulling molding is performed in both directions at the same time.

[0030] The combined core pulling mechanism 100 includes a fixed template 110, a movable template 120, a shovel base 130, an inclined guide ...

[0046] Please refer to Figure 10 , the present invention provides an injection mold 10 for producing plastic products. The injection mold 10 includes a combined core pulling mechanism 100 , a fixed mold seat plate 400 and a movable mold seat plate 300 . Wherein, the basic structure, principle and technical effect of the combined core-pulling mechanism 100 are the same as those of the first embodiment. For a brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0047] In this embodiment, the movable mold base plate 300 is connected to the movable platen 120, the fixed mold base plate 400 is connected to the fixed mold plate 110, and the movable mold base plate 300 and the fixed mold base plate 400 are relatively installed on two sides of the injection molding machine (not shown). On the side, the injection molding machine can drive the movable platen 120 close to or away from the fixed plat...

Abstract

The invention discloses a combined core-pulling mechanism and an injection mold and relates to the technical field of molds. The combined core-pulling mechanism comprises a slider angle pin, a first slider, an angle lifter and a guide seat. The slider angle pin extends into the first slider and is in sliding fit with the first slider. The first slider is provided with a guiding sliding groove. Theangle lifter is arranged in the guiding sliding groove in a sliding manner and is in sliding fit with the guide seat. The first slider can slide in a first direction under the action of the slider angle pin during mold opening, so that the angle lifter slides relative to the guide seat in a second direction under the abutting-against action of the groove wall of the guiding sliding groove. The first direction and the second direction intersect. Compared with the prior art, the combined core-pulling mechanism can complete core pulling actions in two different directions at the same time, the core pulling structure is simplified, the occupied space is reduced, and the mold manufacturing cost is lowered; and besides, the core pulling process is stable and reliable, and the product formationquality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a combined core-pulling mechanism and an injection mold. Background technique [0002] At present, in the design and manufacture of injection molds, if the product needs to be core-pulled in two different directions, two sets of different core-pulling mechanisms are usually used for core-pulling respectively. In this way, both sets of core-pulling mechanisms are installed in the mold, which has a complex structure and takes up a lot of space, resulting in an increase in the size of the mold base, an increase in the cost of mold manufacturing, and the core-pulling process is complicated, and there are errors in the cooperation between parts. Molding quality is low. Contents of the invention [0003] The problem solved by the present invention is how to simultaneously complete core-pulling actions in two different directions, simplify the core-pulling structure, reduce occupied sp...
