Abstract
The utility model discloses an improved three-plate mould body structure convenient for flow channel processing. The improved structure comprises a mold body used for plastic molding, wherein the flow channel processing in the mold body is in a stepped hole form; a section of flow channel close to the middle plate is designed to be an embedded bushing; a tolerance clearance is formed between the bushing and the mold body, so that a spliced mold body flow channel structure is formed; a conical central flow channel is formed in the axial direction of the bushing; and the size of the central flow channel is matched with the size of the corresponding processed electrode. According to the mode, the utility model discloses an improved three-plate mould body structure convenient for flow channel processing, the mold body flow channel electrode processing is convenient, the electrode strength is improved, pouring gate polishing of the mold body is easily performed, the manufacturing is simple, the production cost is reduced, the production efficiency is obviously improved, and the improved structure has good application prospect and practical significance.
Description
Technical field
The utility model relates to mechanical-moulded technical field, particularly relates to a kind of three template die dies that are easy to runner processing and improves structure.
Background technology
Injection mold is the important process equipment in the plastic injection-moulded production, and it generally is made up of six big systems, and running gate system is an important component part in the injection mold six big systems, and it refers in the mould by the injector nozzle to the feeding-passage the die cavity.The structure of the performance to plastic whether reasonable in design, size, inside and outside quality and the mould of running gate system and the utilization rate of plastics etc. have considerable influence.The die of three template dies forms the die cavity of injection mo(u)lding after assembling, therefore, the correspondence position of die will be processed corresponding runner during design, runner in the actual production on the die and cast gate generally adopt discharge processing, and in common die structure the electrode processing difficulties, and the intensity of electrode is very weak, in discharge process, the loss of electrode is very big, makes production cost increase greatly.
Summary of the invention
The technical problem that the utility model mainly solves provides a kind of three template die dies that are easy to runner processing and improves structure, improves electrode processing and the polishing of die cast gate, improves pole strength, obviously cuts down finished cost simultaneously and the die architecture advances of process time.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts provides a kind of three template die dies that are easy to runner processing and improves structure, comprising: the die that is used for plastic rubber shaping; It is characterized in that: the runner processing in the described die is the shoulder hole form, wherein one section runner near intermediate plate is designed to Embedded cylindrical edge cover, guarantee fit clearance between described cylindrical edge cover and the described die, monolateral gap is about 0.025mm, forms inlaid type die flow passage structure; Described cylindrical edge sleeve upwards is provided with the center flow channels of taper, its size and the size coupling of processing used respective electrode.
Preferably, the die bottom wall thickness under the described edge cover bottom surface should guarantee the local strength of die, and general thickness is not less than 5mm.
Preferably, the center flow channels of described edge cover is bigger than the runner at its corresponding die diapire center, and its section difference is about 0.1mm.
The beneficial effects of the utility model are: provide a kind of three template die dies that are easy to runner processing to improve structure, make things convenient for the processing of die runner electrode, improve pole strength, be easy to the polishing of die cast gate, make and simply, both be conducive to be lowered into the product cost, production efficiency is significantly improved, have good application prospects and practical significance.
Description of drawings
Fig. 1 is the generalized section that a kind of three template die dies that are easy to runner processing improve structure;
Fig. 2 is the structural representation of cylindrical edge cover;
Fig. 3 is the enlarged diagram of cylindrical edge cover center flow channels and die diapire center flow channels cooperation place;
The mark of each parts is as follows in the accompanying drawing: 1, die; 2, cylindrical edge cover.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also accompanying drawing 1 to Fig. 3, the utility model embodiment comprises:
A kind of three template die dies that are easy to runner processing improve structure, comprising: the die 1 that is used for plastic rubber shaping; It is characterized in that: the runner processing in the described die 1 is the shoulder hole form, wherein one section runner near intermediate plate is designed to Embedded cylindrical edge cover 2, guarantee fit clearance between described cylindrical edge cover 2 and the described die 1, monolateral gap is 0.025mm, forms inlaid type die flow passage structure; Described cylindrical edge cover 2 axially is provided with the center flow channels of taper, its size and the size coupling of processing used respective electrode.Die bottom wall thickness ξ under the described edge cover bottom surface should guarantee the local strength of die, and ξ generally is not less than 5mm.The center flow channels of described cylindrical edge cover 2 is bigger than the runner at its corresponding die 1 diapire center, and its section difference λ is about 0.1mm.
A kind of three template die dies that are easy to runner processing of the utility model improve structure, make things convenient for the processing of die runner electrode, improve pole strength, be easy to the polishing of die cast gate, significantly reduce production costs simultaneously.Improve the processing of counterbore part in the die of back and can adopt CNC processing, and the processing of runner taper hole can be machined directly to the position by the line cutting in the edge cover, thereby the processing capacity of cast gate on the die is reduced greatly, the difficulty of processing of electrode is reduced, and intensity is improved; The loss of electrode reduces when making discharge simultaneously, thereby die manufacturing cost is reduced greatly, and production efficiency is significantly improved, and has good application prospects and practical significance.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model description to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
