Abstract

The utility model provides a shaping is with location mounting of large-scale mould, on the inboard of the outer module of each unit module, lower extreme edge department respectively sets up a shape, the unanimous slot of size and a location mounting, wherein, two fixed screws have been seted up on each slot at least, and the shape of each location mounting, size and slot cooperation, and seted up T style of calligraphy hole on the relative position that corresponds fixed screw, utilize fixed screw to fix a position the mounting spiral shell admittedly on the upper and lower slot of outer module, borrow this location and connect interior module, module and outer module can become an organic whole in making. The positioning and fixing pieces enable the inner module to be easily, rapidly and accurately and stably fixed on the inner side of the outer module, and the upper end and the lower end of the inner module are fixed by the positioning and fixing pieces, so that the problem of uneven thickness of a formed product caused by moving or shifting and the like due to material injection pressure is solved.

Description

Positioning and fixing piece of large-scale mould for molding

Technical Field

The utility model provides a location mounting especially provides a location mounting of the large-scale mould is used in shaping that the adjustment does not spend labour and time and can pinpoint.

Background

The large-sized mold for molding is, as the name suggests, a mold for molding which is bulky in volume and heavy in weight. Based on the actual requirements of manufacturing, assembling, material injection and the like, most of the templates are composed of a plurality of fixed templates and a plurality of movable templates, even if the templates are composed of a large number of templates, the weight of a single template is hundreds of kilograms, the template is not movable by a single person, and most of the templates depend on overhead travelling crane hanging and moving operation, so that the adjustment, positioning and other operations of the templates need to take a lot of labor and time.

The adjusting and positioning method of the existing large-scale mold for molding uses individual positioning bolts as main adjusting and positioning purposes, as shown in fig. 1-2, which are a plan view of the large-scale tire molding mold and a schematic plan view of a unit module; the large tire forming mold 1 is formed by combining a plurality of unit modules 10, each unit module 10 is formed by combining an outer module 100 and an inner module 101 into a unit tire mold cavity groove, wherein at least two groups of pull nails 102 are arranged between the outer module 100 and the inner module 100 for stably positioning the distance between the inner module 101 and the outer module 100, but defects such as nonuniform thickness, nonuniform size, local indentation and the like of a formed product can be caused due to uneven internal pressure during material injection, and inconvenience in assembly and adjustment operation can be caused due to the fact that the inner module 101 is required to be implemented in implementation, so that the need of improvement is met.

In view of this, the inventor made a series of arrangement studies aiming at the advantages and disadvantages of the adjustment and positioning method of the conventional large-scale mold for molding and the production method thereof, and finally made the positioning and fixing member of the large-scale mold for molding according to a plurality of test results, so as to provide a positioning and fixing member which has a simple structure, is easy to assemble, can be positioned quickly and accurately, is stable and fixed, and can not damage the molded product.

SUMMERY OF THE UTILITY MODEL

The present invention provides a positioning and fixing member for a large-sized mold for molding, and more particularly, to a positioning and fixing member which has a simple structure, does not require labor and time for adjustment, can reliably position a mold plate, and does not damage a molded product.

The utility model aims at providing a location mounting of large-scale mould is used in shaping, the inboard upper and lower end department of the outer module of each unit module respectively sets up a shape, the unanimous slot of size and a location mounting, wherein, two fixed screws have been seted up on each slot at least, and the shape of each location mounting, size and slot cooperation to set up T style of calligraphy hole on the relative position that corresponds fixed screw, utilize this fixed screw spare will fix a position the mounting spiral shell admittedly on the upper and lower slot of outer module, borrow this location and connect interior module, make interior module with outer module can firmly become an organic whole.

The positioning and fixing pieces can easily, quickly, accurately and stably fix the inner module on the inner side of the outer module, and the upper end and the lower end of the inner module are fixed by the positioning and fixing pieces, so that the problem of uneven thickness of a formed product caused by moving or shifting of injection pressure and the like is solved.

Detailed Description

In order to further understand and identify the objects, features and functions of the present invention, the following drawings are used for illustration:

please refer to fig. 3 to 5, which are schematic diagrams of a three-dimensional exploded view, a plan view of a usage state of the embodiment of the present invention, and a plan view of a unit module. 3-5, the utility model discloses respectively set up a shape, the unanimous location mounting 103 of size at the inboard upper and lower extreme edge department of outer module 100 of each unit module 10, borrow this can fix a position fast and accurate, connect interior module 101 firmly, make inside and

outside module

101, 100 two firmly become an organic whole, then its shaping finished product quality can be stable unchangeable. The inner side of the outer module 100 is provided with a groove 100a having the same shape and size at the upper and lower end edges, the groove 100a is provided with at least two fixing screw holes 100b, the positioning and fixing member 103 is matched with the groove 100a in shape and size, and a T-shaped hole 103a is provided at the corresponding position of the fixing screw hole 100b, the positioning and fixing member 102 is screwed and fixed on the groove 100a of the outer module 100 by a fixing screw member, thereby the inner module 101 is quickly and accurately positioned and firmly fixed at the inner side of the outer module 100, and the formed product can have uniform thickness and stable quality.

The above description is only for the best embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can easily think of the changes or modifications within the field of the present invention, and all the changes or modifications can be covered within the scope of the present invention.
