Abstract
The utility model discloses a pouring system for a U-shaped member injection mold. The pouring system comprises a pin-point gate and a reinforcing bar which are arranged in the middle of a connection section in a U-shaped member, wherein the pin-point gate is connected to one side face of the connection section, and the reinforcing bar is connected to the other side face of the connection section. The stress of the U-shaped member, generated during contraction, is eliminated through the reinforcing bar, so that the strength and stiffness of the U-shaped member are improved, the contraction deformation of the U-shaped member is prevented, and meanwhile, the overall mobility of plastics can be improved by the reinforcing bar.
Description
Technical field
The utility model relates to the mould of plastics industry, particularly a kind of running gate system of U-shaped injection mold.
Background technology
Running gate system is the passage that plastic cement solution enters die cavity.Reasonably injection system structure is for guaranteeing that the working of plastics quality plays a part very important, gas discharges in the form of running gate system and plastic cement solution, die cavity etc. are closely related, and can fill the type condition to filling speed, filling time, die cavity temperature Germany and play regulating action, yet the defective such as irrational running gate system can cause that pore, shrinkage cavity are sent, cold shut and poor surface smoothness.
As shown in Figure 1 a kind of U-shaped comprises symmetrical straightway A, by the straightway A bending segment B of bending downwards, and the linkage section C that bending segment B is coupled together, and straightway A is hollow-core construction, and bending segment B and linkage section C are solid construction.Due to wall thickness thicker cool time of moulding long, can produce larger contraction, this U-shaped after injection moulding is cooling, the pars intermedia branch of linkage section C produces larger distortion, is having a strong impact on the quality of product.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of running gate system of U-shaped injection mold, to realize improving the purpose of moulding quality.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of running gate system of U-shaped injection mold comprises being arranged on middle spot pouring mouth and the reinforcement of described U-shaped middle connecting segment that described spot pouring mouth is connected to the side of described linkage section, and described reinforcement is connected to the another side of described linkage section.
Preferably, described reinforcement is solid construction, and its diameter is 1/3rd of described U-shaped diameter.
Pass through technique scheme, the running gate system of U-shaped the injection mold that the utility model provides, eliminate U-shaped stress that produces by reinforcement in contraction process, the strength and stiffness of U-shaped have been improved, prevented the contraction distortion of U-shaped, reinforcement can also improve the mobility of plastic monoblock simultaneously.Automatically reinforcement is excised by mould after injection moulding is completed, can not affect the exterior quality of U-shaped.
Description of drawings
In order to be illustrated more clearly in the technical scheme in the utility model prior art and embodiment, the below will do to introduce simply to the accompanying drawing of required use in prior art and embodiment description.
Fig. 1 is the structural representation of a kind of U-shaped;
Fig. 2 is the structural representation of the running gate system of disclosed a kind of U-shaped the injection mold of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of running gate system (with reference to Fig. 2) of U-shaped injection mold, comprise and be arranged on U-shaped middle connecting segment C middle spot pouring mouth 11 and reinforcement 12, spot pouring mouth 11 is connected to the side of linkage section C, and reinforcement 11 is connected to the another side of linkage section C.
Wherein, reinforcement 12 is solid construction, and its diameter is 1/3rd of U-shaped diameter.
The utility model is eliminated U-shaped stress that produces by reinforcement in contraction process, improved the strength and stiffness of U-shaped, has prevented the contraction distortion of U-shaped, and reinforcement can also improve the mobility of plastic monoblock simultaneously.Automatically reinforcement is excised by mould after injection moulding is completed, can not affect the exterior quality of U-shaped.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
1. the running gate system of a U-shaped injection mold, it is characterized in that, comprise being arranged on middle spot pouring mouth and the reinforcement of described U-shaped middle connecting segment, described spot pouring mouth is connected to the side of described linkage section, and described reinforcement is connected to the another side of described linkage section.
2. the running gate system of a kind of U-shaped injection mold according to claim 1, is characterized in that, described reinforcement is solid construction, and its diameter is 1/3rd of described U-shaped diameter.
