Embodiment Construction

[0023] Embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0024] As shown in the figure, the core-pulling injection mold for producing multi-slanted hole products is mainly used for the production of auto parts and speaker parts, including an upper plate 1, an upper parting plate 2, and a lower parting plate stacked in sequence from top to bottom. Model plate 3 and lower plate 4, described upper parting plate 2 and lower parting plate 3 are provided with a mold core, and the mold core includes an upper mold kernel 8 fixed in the lower parting plate 3 and a mold core fixed in the lower parting plate 3. The lower mold core 7 in the template 3, the upper mold core 8 and the lower mold core 7 cooperate to form a cavity 10, the cavity 10 is connected with the injection pipe 11, and the lower mold core 7 is provided with several The lower core-pulling slideway 72 runs through obliquely. The lower core-pulling slideway ...

Abstract

The invention relates to a core pulling injection mold for manufacturing multi-inclined-hole products, and mainly solves the problems about complex structure and cumber in operation during use of the existing injection mold, especially the difficulty in machining small workpieces and multi-inclined-hole workpieces. A plurality of inclined-penetration lower core pulling slideways (72) are arranged in a lower mold cavity (7); a lower core pulling elastic rod (5) is matched with the interior of each lower core pulling slideway (72) in a sliding way; a lower pulling needle (52) is arranged at the top end of each lower core pulling elastic rod (5) and stretches into a cavity (10), and the other end of each lower core pulling elastic rod (5) is in top press fit with a lower plate (4); lower elastic resetting parts (51) driving the lower core pulling elastic rods (5) to be far away from the cavity (10) are arranged between the lower core pulling elastic rods (5) and the lower mold cavity (7). The core pulling injection mold is simple in structure and convenient to operate, and can well realize multi-core-pulling operation and large-angle core pulling operation.

Description

technical field [0001] The invention relates to an injection mold, in particular to a core-pulling injection mold for producing products with multiple oblique holes. Background technique [0002] Plastic molds are commonly used molds in the field of existing product manufacturing, and their usual structures include two-plate molds, three-plate molds, I-shaped molds and straight body molds. In the production of injection molding products, the step of core pulling is often involved, and the core pulling methods vary widely, one of which is oblique hole core pulling. In the current market, the slanted holes of products are constantly diversified. For parts with multi-directional slanted holes, if a single slanted hole is used for core-pulling in stages, it is necessary to configure a set of core-pulling devices for each slanted hole, which will cause the entire mold structure to be huge. , especially when processing small-sized workpieces, it is difficult to meet the structura...
