Abstract
The utility model provides a can be at lamp shade mould of lamp shade afterbody preparation rivet hole, including lamp shade mould, fore -set, cam mechanism, fixed column, wire spring, lamp shade mould lower part bilateral symmetry is equipped with the through -hole, the through -hole runs through the outside and the die cavity of lamp shade mould, the bilateral symmetry of lamp shade mould is equipped with the fixed column, install the disc cam on the fixed column, fore -set one end with the surface of disc cam contacts, the other end of fore -set stretches into in the through -hole, the middle part of fore -set with still install wire spring between the fixed column. The beneficial effects of the utility model are that: 1, adopt the disc cam to control the ejector pin, can not receive the high temperature influence to job stabilization, the simple structure of device, long service life, convenient maintenance.
Description
Technical field
The utility model relates to mould applications, particularly relates to and relates in particular to a kind of lampshade mould that can make at lampshade afterbody rivet hole.
Background technology
A lot of lampshades all will be installed a metal cap at afterbody, general is all to adopt the mode of riveted joint to match with lampshade, in order to ensure the fixing reliability of afterbody of metal cap and lampshade, generally need to be provided with two symmetrical rivet holes at the afterbody of lampshade, this rivet hole is all generally that the pulled core structure of pattern tool in the compressing process of glass is realized.
The pulled core structure of existing lampshade mould is all generally to adopt air-driven mode to handle push rod; lampshade afterbody is loosed core to form rivet hole; cylinder is worked under higher temperature environment; be easy to break down; downtime and maintenance cost are increased; and, when Pneumatic Transmission work, can, because air pressure fluctuation causes the unstable of push rod work, easily produce waste product.
Utility model content
In order to solve above-described technical problem, the utility model provides following technical scheme:
A kind of lampshade mould that can make at lampshade afterbody rivet hole, comprise lampshade mould, fore-set, cam mechanism, fixed leg, wire spring, described lampshade mould bottom bilateral symmetry is provided with through hole, described through hole runs through outside and the die cavity of described lampshade mould, the bilateral symmetry of described lampshade mould is provided with fixed leg, on described fixed leg, disc cam is installed, described disc cam is connected with the drive unit that drives its rotation, described fore-set one end contacts with the surface of described disc cam, the other end of described fore-set stretches in described through hole, between the middle part of described fore-set and described fixed leg, wire spring is also installed.
Compared with prior art, the beneficial effects of the utility model are:
1, adopt disc cam to handle push rod, can not be subject to temperatures involved, and working stability, device simple in structure, long service life, convenient for maintaining.
According to the detailed description to the utility model specific embodiment by reference to the accompanying drawings below, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Brief description of the drawings
Hereinafter describe specific embodiments more of the present utility model in detail in exemplary and nonrestrictive mode with reference to the accompanying drawings. In accompanying drawing, identical Reference numeral has indicated same or similar parts or part. It should be appreciated by those skilled in the art that these accompanying drawings may not draw in proportion. In accompanying drawing:
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of lampshade mould that can make at lampshade afterbody rivet hole as described in Figure 1, comprise lampshade mould 1, fore-set 2, disc cam 3, fixed leg 4, wire spring 5, described lampshade mould 1 bottom bilateral symmetry is provided with through hole 6, described through hole 6 runs through outside and the die cavity of described lampshade mould 1, the both sides of described lampshade mould 1 are fixed with fixed leg 4, on described fixed leg 4, disc cam 3 is installed, described disc cam connects promising its provides the engine of rotary power, described fore-set 2 one end contact with the surface of described disc cam 3, the other end of described fore-set 2 stretches in described through hole 6, between the middle part of described fore-set 2 and described fixed leg 4, wire spring 5 is also installed. when melted glass flows into after lampshade mould 1, before mold (not marking in figure) is depressed, disc cam 3 drives push rod to head into the die cavity of lampshade mould 1, makes unfashioned lampshade form the hemispherical dimples of rivet hole. now patrix is depressed, and makes lamp shade forming, and after patrix die sinking, the whole shape of lampshade is all molded, and wire spring 5 exits die cavity with fore-set 2, and the lampshade of moulding is taken out from die cavity by unloading device.
So far, those skilled in the art will recognize that, illustrate and described of the present utility model multiple exemplary embodiment although detailed herein, but, in the situation that not departing from the utility model spirit and scope, still can directly determine or derive many other modification or the amendment that meet the utility model principle according to the disclosed content of the utility model. Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
