Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.
As shown in Figure 1, product a2 is plastic casing, because its plastic casing is curved surface, the opening a1 width at two ends is narrower, width in the middle of product a2 is comparatively large, if directly adopt side-drawing mechanism of the prior art, then easily setting product a2 cannot the demoulding, further, core plan in the process departed from owing to the bottom margin of product a2 being also provided with buckle and projection.Must make in the process of loosing core core can change its width could from compared with opening a1 go out to detach, the mould that therefore the present embodiment designs with regard to this product a2 has following structure.
As Figure 2-3, a kind of injection moulding side pumping mode lamps structure, comprise dynamic model 1, cover half 2, be installed on the core-pulling mechanism 3 on cover half 2, dynamic model 1 arranges sprue gate, the center of described cover half 2 is provided with the middle chute 21 along direction of loosing core, the both sides of described middle chute 21 are respectively arranged with the symmetrical left chute 22 that direction tilts and court looses core and right rail 23, described core-pulling mechanism 3 comprises the left insert 32 coordinated with the slippage of left chute 22, the slide block 31 coordinated with the slippage of middle chute 21, the right insert 33 coordinated with right rail 23 slippage, the top width of described slide block 31 be less than bottom width and two sides respectively with described left insert 32, right insert 33 is connected by wood side-guide slippage, the bottom of described slide block 31 is provided with the driving cylinder 4 driving it to move along direction of loosing core.The top of the left insert 32 in core-pulling mechanism 3, right insert 33 and slide block 31 forms die cavity, and plastic product a2 is shaping on the curved surface of left insert 32, right insert 33 and slide block 31 top composition.
By above-mentioned setting, drive cylinder 4 Direct driver slide block 31 to carry out horizontal linear direction along direction of loosing core to move, top width due to slide block 31 is less than bottom width, two sides are in the process retreated, will to make more than middle space empty out, now drive left insert 32 by the sidewall of slide block 31, right insert 33 offsets toward in, thus make left insert 32, right insert 33 can inside contract by net, thus be separated from the surface of product a2, now larger pulled core structure is by after the fractionation of shape and combination adjustment, its Breadth Maximum when the demoulding is diminished, thus can make to be convenient in demoulding, product a2 can not be damaged in forming process, while improving the ratio of briquetting of product a2, by the mode of slippage, its movable contact face is very large, support and the degree of stability of motion also improve thus.
Slide block 31 comprises the slipping part 34 removably connecting and coordinate with middle chute 21.Slipping part 34 is the iron block of T-shaped, slipping part 34 scribbles lubricating oil, the top of slipping part 34 is fixed in the bottom of slide block 31 by multiple bolt, slipping part 34 on slide block 31 is arranged to detachably, thus slide block 31 is convenient for changing in the process used, thus improves the quality of production, reduce maintenance cost, only need to change and be used for the slipping part 34 of slippage, whole slide block 31 entirety need not be changed, thus cost-saving.
The exit of middle chute 21 is provided with limited block 5, and the confined planes of limited block 5 has step shape, makes sliding and position limitation more stable.Limited block 5 abuts with the sidewall of slide block 31.Slide block 31 can be made more stable in the process of movement by limited block 5, and limited block 5 limits the lateral attitude of slide block 31 by sidewall, slide block 31 glide direction is stablized, prevent vibrations and skew.
As shown in Figure 2, dynamic model 1 is provided with shock absorber part 6, and described shock absorber part 6 is arranged on four angles with dynamic model 1.By arranging shock absorber part 6, making dynamic model 1 can reduce vibrations when die sinking, improving the ratio of briquetting of product a2.Shock absorber part 6 is spring, by the elasticity of spring, can make dynamic model 1 motion and die sinking process in can reduce mechanical shock.
Cover half 2 has injection molding channel mouth 7, described injection molding channel mouth 7 is provided with metal o-ring 8, and described metal o-ring 8 is provided with locating hole 81 and is fixedly connected with cover half 2.Metal o-ring 8 effectively can prevent the waste of plastics in the process of injection moulding and can play certain protective effect to the temperature of plastics.While adopting metal o-ring 8 can improve the performance of its sealing, there is longer service life.
As described in Figure 5, plastics enter from injection molding channel mouth 7, forming surface is flow to by the runner on slide block 31, after plastic shaping, loose core in process in die sinking, slide block 31 first outwards exits, thus affects left and right insert 33 inwardly to move, thus the width of core-pulling mechanism 3 inside is diminished, thus product a2 can be made along disengaging forming cavity.This design have facilitate core_pulling demoulding, stable effect of loosing core, and improve the quality of production, reduce maintenance cost.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
