The specific embodiment

Below, the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.

As depicted in figs. 1 and 2, mould locating guide device of the present utility model, comprise the guide pillar that is fixedly connected on the dynamic model 1, be square guide plate 11 and be fixedly connected on the guide pin bushing 21 that constitutes by two wear-resistant blocks on the cover half 2, formed the gathering sill that holds square guide plate 11 between two wear-resistant blocks, one end of guide plate 11 is fixedly connected on the dynamic model 1, the other end stretches out the end face of dynamic model 1, socket-connect by two wear-resistant blocks guide pin bushing 21 that constitutes and the guide plate 11 that stretches out dynamic model 1 end face, be to slide in guide plate 11 gathering sill that can between by two wear-resistant blocks, form, finish dynamic model and cover half and close location and guiding in the closed procedure, and guide plate 11 and the guide pin bushing 21 that socket-connects with it are separately positioned on the periphery of dynamic model 1 and cover half 2, also promptly, mould locating guide device of the present utility model is arranged on the periphery of dynamic model and cover half.Therefore, when the mould of using the utility model manufacturing is produced, even if cover half heat and dynamic model is cold, and when its temperature difference is bigger, the mfg. moulding die dynamic model is different with the employed steel heat swell increment of cover half, then in the dislocation of the corner angle portion of mould, it is the magnitude of misalignment maximum that dynamic model and cover half close the property at parts of edges and corners that closes, and it is less to close the magnitude of misalignment of the periphery that closes at dynamic model and cover half, in other words, in process of production, the pressure of the locating guide device that is arranged on the active and inactive mold periphery with less, that is, is used that mould of the present utility model can be avoided because the thermal expansion amount difference that the different temperature difference of active and inactive mold cause, thereby make the not easy to wear of locating guide device, burn out with stuck, improved the service life and the production efficiency of mould.

A kind of preferred implementation of the present utility model is, square guide plate and wear-resistant block are separately positioned on the peripheral central of dynamic model and cover half, as Fig. 1 or shown in Figure 2, its principle is the same, the magnitude of misalignment of the periphery central authorities of dynamic model and cover half is minimum, therefore, wearing and tearing that mould locating guide device of the present utility model will at utmost prevent this device are set, burn out, further improve the service life and the production efficiency of mould with stuck in the peripheral central authorities of dynamic model and cover half.

Another kind of preferred implementation of the present utility model is, as shown in Figure 2, also be provided with deep gouge 12 on the dynamic model 1, one end of square guide plate 11 is fixedly connected in the deep gouge 12, the other end stretches out the end face of dynamic model 1, then, square guide plate will more firmly be difficult for rocking with being connected of dynamic model, the location of favourable and dynamic model and cover half.Also be provided with the deep gouge 22 that holds square guide plate 11 on the cover half 2, wear-resistant block 21 is embedded in the both sides in the deep gouge 22, as shown in Figure 1.Therefore, when dynamic model 1 and cover half 2 close when closing, the end that square guide plate 11 stretches out the dynamic model end face will insert in the deep gouge 22 of cover half 2, its both sides are established by two wear-resistant blocks, 21 folders and are provided lubricated, make dynamic model and cover half close location and the more smooth and easy and driving fit of guiding when closing, favourable and production and processing goes out high-quality injecting products.

Another preferred implementation of the present utility model is, as shown in Figure 2, dynamic model 1 is provided with the screw hole and the pin hole of a cover, and square guide plate 11 is provided with screw counterbore and pin hole, and square guide plate 11 is fixedlyed connected with pin with bolt with pin hole with the screw hole on the dynamic model 1; Cover half 2 is provided with screw hole, and wear-resistant block 21 is provided with the screw counterbore, and wear-resistant block 21 and cover half 2 are connected with bolting.Use bolt and pin resting guide and dynamic model, use bolting wear-resistant block and cover half, help guide plate from dynamic model, or wear-resistant block disassembles guide plate that more renews or wear-resistant block, thereby the service life of prolongation mould active and inactive mold from cover half, promptly, when locating guide device of the present utility model, after promptly guide plate and wear-resistant block were worn, the guide plate and the wear-resistant block that more renew got final product.

If dynamic model is provided with the up and down screw hole and the pin holes of two covers, then square guide plate can with dynamic model on wherein the screw hole of a cover fixedly connected with pin with bolt with pin hole; When the screw hole of a cover was fixedlyed connected with pin with bolt with pin hole above on square guide plate and the dynamic model, square guide plate stretched out an end of dynamic model end face with longer, as shown in Figure 3; When the screw hole of a cover is fixedlyed connected with pin with bolt with pin hole below on square guide plate and the dynamic model, square guide plate stretches out an end of dynamic model end face will lack, as shown in Figure 4.Therefore, square guide plate can be in the deep gouge of dynamic model or on a little or a little down fixing, promptly can regulate the length that guide plate stretches out the dynamic model end face, thereby unlikely when producing, the guide plate that stretches out the dynamic model end face becomes obstacle, makes things convenient for manipulator or operator's die sinking pickup.In like manner, if dynamic model is provided with the screw hole and the pin hole of more covers, then square guide plate can be chosen on the dynamic model wherein the screw hole of a cover wantonly and fixedlys connected with pin with bolt with pin hole, further facilitates actual production operation.

Another preferred implementation of the present utility model is, as shown in Figure 5, also be provided with positioning convex 13 on the dynamic model 1, also be provided with a detent 111 on the square guide plate 11, the detent 111 of square guide plate can be stuck on the positioning convex 13 of dynamic model 1, then, the fixing of guide plate and dynamic model will be more firm, using on the fixing basis of bolt and pin, guide plate and dynamic model fixedly are become one, the location and the guiding of favourable and mould.Be provided with the screw hole and the pin hole of many covers in conjunction with above-mentioned dynamic model, also a plurality of detents can be set on the square guide plate, then this kind preferred implementation can realize regulating the length that guide plate stretches out the dynamic model end face too, and its connection is more firm, both make things convenient for actual production operation needs, also can realize the needs of dismounting and change.

In a word, the described several embodiments of the foregoing description are not represented all implementations of the utility model; Above embodiment is not that every basic structure is similar with the utility model or identical to concrete qualification of the present utility model, all should be within protection domain of the present utility model.
