Abstract

The utility model discloses a chopsticks finial production die comprising an upper die, a lower die, a heart, and at least one impression positioned on the upper die and the lower die respectively, wherein the parting surface of the impressions of the upper die and the lower die are positioned on the flat surface of the finial diagonal. The utility model has the advantages of that the parting surface of the cast is on the corner line of the finial after pouring and coincides with the corner line of the finial, thereby processing the parting surface as well as the corner line, and solving the problem that the parting surface needs to be proceed separately but still leaving parting line one the flat surface.

Description

Chopsticks finial production mould

Technical field

The utility model relates to a kind of production equipment of chopsticks finial, particularly a kind of production mould of chopsticks finial.

Background technology

In order to promote the class of the environment of having dinner, a lot of star hotels and medium and high-grade restaurant often all have very high requirement to meal with the outward appearance and the material of chopsticks, often select aspect material that hardness is big, density is high, high-grade timber that glossiness is good after the surface treatment or melamine material, and often all require to stud with decoration in the chopsticks head part.Maximum decorations is the finial that puts on chopstick head through casting processing at present, finial is numerous in variety, adopt gold-plated or silver-colored or chromium often, and at present external and the use of dining room, Hong Kong favorite often by the finial of metal similar packet header samples such as fine copper.This simple metal finial adopts die casting to process, and existing mould since its die joint all be chosen in and carry out on the plane of finial, on the product surface after the die sinking, can stay coarse die joint (as shown in Figure 1) like this, need carry out fine finishining to it, and the complexity that processing technology is become has increased manufacturing cost.

Invention constitutes

The purpose of this utility model is to overcome the deficiencies in the prior art part and a kind of chopsticks finial production mould high-quality, low cost of manufacture of producing is provided.

The purpose of this utility model realizes by following approach.

A kind of chopsticks finial production mould, it comprises upper die and lower die and core, be respectively arranged with the die cavity of at least one on patrix and counterdie, its structural feature is: the die joint of the corresponding die cavity of described patrix and counterdie is positioned at the plane at finial diagonal place.

To go up, the die cavity die joint of counterdie is arranged on the plane at diagonal place of finial, like this behind casting complete, to be positioned on the corner line of finial at formed die joint on the foundry goods, overlap with the corner line of finial, then in the processing corner line, can be worked into the die joint that is positioned at herein in the lump, even (this is not processed, because it is to overlap with the corner line of finial itself, therefore it also can not have influence on the quality of this finial, the required cost of its finial of producing of dying is low, processing is simple), it has changed finial that existing mould produces needs separately in addition the die joint on the finial processed and but still can't change the shortcoming that it stays the shortcoming of parting line (closing line) in the plane and makes the processing of chopstick head become complicated and increase its manufacturing cost.

Because finial is very little, therefore can in a mould, a plurality of die cavities be set simultaneously, so just can in a mould, produce a plurality of finials simultaneously, can save the required cost of die sinking, thereby reduce the production cost of chopsticks finial.

The die cavity end at that end finial place that combines with the chopsticks body in the described upper die and lower die die cavity is provided with the radian that distributes along mold cavity axis.

Distribute becoming to have radian with the cavity design at that end finial place of chopsticks body combination in the mold cavity, casting the finial that processes like this will have along the arc of axis distribution excessive at its outer peripheral face near that end of chopsticks body, thereby make the transition between chopsticks body and the finial more natural, smooth, thereby further increase the aesthetic measure of chopsticks, and then promote the class of these chopsticks.

Described core be positioned at combine that end place on the finial with the chopsticks body the core diameter greater than other position on the core.

Adopt such core, the inner chamber of the finial that processes is being positioned at all the other positions that are slightly larger than the finial inner chamber with the position of chopsticks body junction, like this when finial and chopsticks body are connected together, to have certain space at binding end between finial and the chopsticks body, can implement injecting glue herein, thereby can avoid gum-injecting port exposed outside, influence the outward appearance of chopsticks.

Described core diameter is a pyramidal structure greater than the position at other position on the core, and the big end of taper is positioned on the core for that end of extracting out.

Described counterdie is provided with the slide block type core-pulling mechanism, and described core is arranged on this slide block.

Adopt the core-pulling mechanism of slide block type, just can easily a plurality of cores in the mould be arranged on the core-pulling mechanism of same slide block type, therefore can significantly reduce loose core the required time and, thereby the production cost of reduction finial.

The sprue gate of described each die cavity is arranged in the last model cavity of die cavity, the die cavity end at that end finial place that the counterdie die cavity combines with the chopsticks body.

The sprue gate is arranged at the end of die cavity, just can makes the sprue gate of watering on the chopsticks finial that outpours be positioned at the end, be convenient to it is handled, the injury that may cause outward appearance in the time of can avoiding deburring.

Counterdie is provided with staggered casting liquid diversion channel, and each die cavity on diversion channel and the mould is conducted, and the sprue gate on diversion channel and the patrix is conducted.

Described core is 718 ^#The import steel.

Described mould is for being processed by the accurate plastics injection of standard.

In sum, advantage of the present utility model is

The utility model is arranged on the die cavity die joint of upper die and lower die on the plane at the diagonal place of finial, like this behind casting complete, to be positioned on the corner line of finial at formed die joint on the foundry goods, overlap with the corner line of finial, then can be worked into the die joint that is positioned at herein in processing in the lump in the corner line, having changed finial that existing mould produces needs separately in addition the die joint on the finial processed and but still can't change it and stay parting line (closing line) in the plane and need and carry out accurately machined shortcoming more again to finial.Simultaneously the utility model also can make core and the cavity structure that has arc-shaped transition between finial and the chopsticks body being provided with on the mould, and the sprue gate on the mould is set in place in the die cavity at place, chopsticks finial end, just can make the sprue gate of watering on the chopsticks finial that outpours be positioned at the end, be convenient to it is handled the injury that may cause outward appearance in the time that deburring can being avoided.Thereby can improve the ornamental of finial that mould thus produces greatly, improved the class of the finial of producing.
