Abstract
The utility model discloses a fixing structure for a hot nozzle and a runner plate of a hot runner system, belonging to fixing structures of hot runner systems in the field of plastic moulds. The structure comprises the runner plate and the hot nozzle, as well as mesons, wherein the top end of the hot nozzle is in planar contact with the bottom surface of the runner plate; the mesons are uniformly arranged on the side surfaces of the runner plate and the hot nozzle and provided with grooves; and the grooves of the mesons are used for buckling and fixing the runner plate and the top end of the hot nozzle from the side surface. The grooves of the mesons tightly press the runner plate and the hot nozzle and can not drive the head of the hot nozzle to deviate due to the deformation of the runner plate, therefore, the structure of the mould is simplified and the cost of the mould is reduced.
Description
Technical field
The utility model relates to the hot mouth and the runner plate fixed structure of the TOP-TIP in plastic mould field, particularly a kind of TOP-TIP.
Background technology
TOP-TIP is a kind of plastic mould parts at present commonly used, and it is with respect to common flow passage, has simplified control, molding cycle is short, economizes in raw materials, the goods cost is low, plurality of advantages such as product quality height.Common TOP-TIP comprises sprue bushing, runner plate and the Re Zui that connects successively, and the temperature control system that is used to heat, its effect is to keep the plastic cement of fusion to inject from injection machine in the die cavity of plastic mould by the high temperature heating, and is therefore very high to insulation and sealing requirements.Wherein, complicated in runner plate and one section installation of hot mouth of TOP-TIP, to guarantee the sealing between runner plate and the hot mouth on the one hand; To consider the hot mouth part of hot mouth and the sealing between the mold cavity on the other hand, thereby must be with hot mouth partial fixing in the mould installing hole, this part does not allow to be offset.In traditional flow passage system mounting means, rely on the mould design corresponding construction and compress runner plate and Re Zui, not only increase die cost, and require very high the accuracy of this die structure size; There are some producers then directly hot mouth to be screwed into heat flux plates abroad at present with screw, need not design corresponding mould structure although it is so and compress runner plate and Re Zui, but runner plate is operated under the condition of high temperature, will inevitably be out of shape because of expansion, especially in large-scale TOP-TIP, the transversely deforming of runner plate is more obvious, this can drive the hot mouth flexural deformation that is attached thereto, thereby influence the sealing of hot mouth and mold cavity, also must set up corresponding structure for this reason and reduce the deformation effect that hot mouth is subjected to.
Summary of the invention
The purpose of this utility model is intended to address the above problem, a kind of simple and effective fixed structure is provided, does not need complicated mould design, just can guarantee runner plate and hot tight-lipped subsides, when hot operation, can not influence the sealing of hot mouth and die cavity again simultaneously because of the transversely deforming of runner plate.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The hot mouth of TOP-TIP and runner plate fixed structure, comprise runner plate and Re Zui, Re Zui top and runner plate bottom surface are plane contact, also comprise the meson of the band groove that evenly is arranged on described runner plate and Re Zui side, and the groove of meson is fastened runner plate and Re Zui top from the side.
The beneficial effects of the utility model are: set up the high-precision mold structure or the screw fixed structure is compared with traditional, only need in this meson structure just runner plate and Re Zui to be compressed with groove itself, and the transversely deforming of runner plate can not influence hot mouth, saved complicated mould structure, structural design is greatly simplified, and reduced die cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, runner plate; 2, Re Zui; 3, meson.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of hot mouth of TOP-TIP and runner plate fixed structure, comprise runner plate 1 and hot mouth 2, hot mouth 2 tops and runner plate 1 bottom surface are plane contact, two mesons 3 that also comprise the band groove that is symmetricly set on runner plate 1 and hot mouth 2 both sides, the groove of meson 3 is fastened runner plate 1 and hot mouth 2 tops from the side, and runner plate 1 and hot mouth 2 are compressed.
Certainly, above embodiment just is explanation rather than restriction the utility model, the above only is preferred embodiment of the present utility model, so all equivalences of being done according to the described scheme of the utility model patent claim change or modify, is included in the utility model patent claim.
Claims (1)
