Description

A mold core pulling structure

technical field

The utility model relates to a mold, in particular to a mold core-pulling structure.

Background technique

A mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. With the development of production, molds are widely used in the production and molding processing of various products because of their advantages such as high production efficiency, good quality, low cost, energy saving and material saving.

When the mold is processing products with shafts such as the shaft part of the clamshell mobile phone, it is necessary to set a core-pulling structure in the mold to process the required shaft.

With the traditional core-pulling structure, the core-pulling process needs to be completed in multiple steps, which is not easy to coordinate, and it is easy to strain the product during core-pulling.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a safe and efficient mold core-pulling structure.

The technical scheme of the utility model is: a core-pulling structure of a mold, including an upper mold core, a lower mold core, a shovel base, a slider, and a shaft core, and a positioning column protruding downward is provided on the lower surface of the upper mold core; The lower part of the core is provided with a shovel base that is symmetrical to the left and right along the positioning column and protrudes downward; the shovel base is a guide block that is bent inward at the lower part; the upper surface of the lower mold core is provided with a left-right symmetrical slider that can slide left and right; The outer side of the slider is connected with the shaft core; the inner side of the slider is provided with a guide shaft matched with the shovel base.

The working principle of the utility model is: when the mold rotating shaft part is processed, the upper mold core and the lower mold core are combined, the positioning column cooperates with the inner side of the slider, the vertical part of the shovel base cooperates with the guide groove in the slider, and the shovel base, The two positioning columns cooperate to position the slider, and the shaft core on the slider processes the required rotating shaft for the product. After the processing is completed, the upper mold core moves upward, driving the positioning column, and the shovel base moves upward. The positioning column and the When the slider is out of contact, the slider moves inward under the guidance of the shovel base, thereby driving the shaft core to be pulled out.

The utility model has the advantages of simple and reasonable structure, convenient use and maintenance, and wide popularization and application value.

Description of drawings

Accompanying drawing is the structure schematic diagram of the present invention, also is abstract with drawing.

Each label in the figure is respectively: (1) upper mold core; (2) lower mold core; (3) (4) shovel base; (5) (6) slider; (7) positioning column; (8) (9) ) shaft core; (10)(11) guide groove.

specific embodiment

Now in conjunction with accompanying drawing, the utility model is further described.

Example

The lower surface of the upper mold core 1 is provided with a positioning column 7 protruding downward; the lower part of the upper mold core 1 is provided with shovel bases 3, 4 which are left and right symmetrical along the positioning column 7 and protrude downward; the shovel bases 3, 4 are The lower part of the guide block is bent inward; the upper surface of the lower mold core 2 is provided with sliders 5, 6 that are symmetrical and can slide left and right; the outer sides of the sliders 5, 6 are connected with the shaft cores 8, 9; the sliders The block 5,6 is provided with guide shafts 10,11 matched with the shovel base 3,4.

Claims (1)

1. mould structure of loosing core comprises upper cores, following die, and the shovel base, slide block, the axle core, it is characterized in that: the upper cores lower surface is provided with the reference column that stretches out downwards; The upper cores bottom is provided with along reference column left-right symmetry and the shovel base that stretches out downwards; Described shovel base is led a piece for what the bottom bent inwards; The slide block that following die upper surface is provided with left-right symmetry and can horizontally slips; The described slide block outside links to each other with the axle core; Be provided with in the described slide block and shovel the axis of guide that base matches.
