Abstract

The utility model provides a front mold bouncing pin structure for preventing a product from being adhered to a front mold. The front mold bouncing pin structure comprises the front mold, a combination mold and bouncing pin structures, wherein two through holes which are used for accommodating the bouncing pin structures are formed in the combination mold; the front mold is arranged at the lower end of the combination mold; each bouncing pin structure comprises a bouncing pin and a light-load spring; each light-load spring is arranged at the upper end of the corresponding bouncing pin, and the light-load spring and the bouncing pin of each bouncing pin structure are arranged in the corresponding through hole of the combination mold together. The front mold bouncing pin structure for preventing the product from being adhered to the front mold is simple, low in processing cost, high in accuracy, small in occupied space, convenient to disassemble and high in practicality.

Description

A kind of front mould bullet needle construction that prevents the sticky front mould of product
Technical field
The utility model relates to mould applications, refers to especially a kind of front mould bullet needle construction that prevents the sticky front mould of product.
Background technology
All the time, in the design and manufacture process of plastic, often there will be the recessed or plagioclase hole of side.Because side is recessed or plagioclase hole different from die sinking direction (vertical or angled), plastic can not direct demold, therefore must Element Design moulding side is recessed or plagioclase hole become mobilizable in mould structure design, be called moving core, before the plastic demoulding, must first carry out undercut, moving core is extracted out, and plastic can the demoulding, and complete this moving core, takes out the mechanism of mountain and reset and is called oblique core-pulling mechanism.Conventionally, the mode of loosing core of oblique slotted hole is rack-and-pinion pulled core structure, though this mechanism can meet the production requirement of such part, along with day by day improving and the raising day by day of labor productivity product appearance quality requirement.
Utility model content
The deficiency existing for prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, and processing cost is low, it is little to take up room, convenient disassembly and the practical front mould bullet needle construction that prevents the sticky front mould of product.
The technical solution of the utility model is achieved in that a kind of front mould bullet needle construction that prevents the sticky front mould of product, comprises front mould, combination die and bullet needle construction; In described combination die, be provided with two and place the through hole that plays needle construction, described front mould is arranged on combination die lower end; Described bullet needle construction comprises bullet pin and underload spring; Described underload spring is arranged on and plays pin upper end, and is together arranged in the through hole of combination die.
A kind of front mould bullet needle construction that prevents the sticky front mould of product of the present utility model, a kind of simple in structure, processing cost is low, high accuracy, little, convenient disassembly and practical takes up room.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of sectional structure schematic diagram that prevents the front mould bullet needle construction of the sticky front mould of product of the utility model
Fig. 2 is a kind of sectional structure schematic diagram that goes out for the first time product that prevents the front mould bullet needle construction of the sticky front mould of product of the utility model;
Fig. 3 is a kind of sectional structure schematic diagram that goes out for the second time product that prevents the front mould bullet needle construction of the sticky front mould of product of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3: a kind of front mould bullet needle construction that prevents the sticky front mould of product, comprises front mould 3, combination die (not indicating in figure) and play needle construction 4; In described combination die (not indicating in figure), be provided with two and place the through hole 21 that plays pin 4, described front mould 3 is arranged on combination die (not indicating in figure) lower end, and forms a PL face 5; Described combination die (not indicating in figure) comprises patrix 3 and counterdie 2, and described patrix 3 is shut described bullet needle construction 4.
Above-mentioned a kind of front mould bullet needle construction, described bullet needle construction 4 that prevents the sticky front mould of product comprises and plays pin 41 and underload spring 42; Described underload spring 42 is arranged on and plays pin 41 upper ends, and is together arranged in the through hole 21 of combination die.
Operation principle: in the time of die sinking, PL face 5 is opened, bullet positive 41 withstands product under the active force of underload spring 42 simultaneously can displacement S, so just can prevent that product is bonded on front mould.
A kind of front mould bullet needle construction that prevents the sticky front mould of product of the present utility model, a kind of simple in structure, processing cost is low, high accuracy, little, convenient disassembly and practical takes up room.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
