Abstract

The invention discloses a kind of connecting line injection molds, including cover half, and the dynamic model being arranged on cover half, it further include the centre hole being arranged on dynamic model, it is provided with multiple cuttings in an axial direction on the inner wall of the centre hole, the section configuration of the cutting is triangle or semicircle, and the cutting is distributed along the even circumferential of centre hole;The centre hole is connect by exhaust tube with vacuum plant.The present invention compared with the existing technology, due to the setting of cutting on the inner wall of centre hole so that exhaust is more smooth and be not easy to plug, it is various because be vented it is bad caused by product defects such as:The problems such as focal spot, gasification, is readily solved.Disclosed by the invention is widely suitable to the Shooting Technique of various products material, have many advantages, such as that formed product is easy, qualification rate is high.

Description

A kind of connecting line injection mold
Technical field
The present invention relates to a kind of mold more particularly to a kind of connecting line injection molds.
Background technology
Injection molding is after resin heating is reached molten condition, and high speed, high pressure are injected into the mold with required shape In the middle, mold is opened after cooling, the method for obtaining molded product.It is continuously improved with the performance of raw materials for plastics production, the zero of every profession and trade Part will be further speeded up to mould Dai Gang, with the process for moulding Dai Mu, be increased increasingly using the ratio of plastic mould, equally to injection mould Higher requirements are also raised for tool, but existing injection mould often will appear lack of fill in die trial production, compressed air is burnt, Inside product the problems such as very high internal stress, surface streamline, melt run, focal spot, the main reason for leading to the problem of these is mold Be vented it is bad cause, therefore usually consider in mold design be solve exhausting problem, the method generally used is in mold Die joint begins to rehearse on air drain dynamic model plus thimble, but effect is undesirable, causes the normally production of product unstable, and product cost is high, Waste is big, and especially focal spot problem does not have tangible improvement.Therefore it is urgent to become mold designer for the focal spot problem of injecting products Problem to be solved.
Invention content
In view of this, the object of the present invention is to provide a kind of connecting line injection mold, carried to solve in background technology To the problem of.
The present invention solves above-mentioned technical problem by following technological means:
A kind of connecting line injection mold, including cover half, and the dynamic model that is arranged on cover half further include being arranged on dynamic model Centre hole, be provided with multiple cuttings in an axial direction on the inner wall of the centre hole, the section configuration of the cutting is triangle Or it is semicircle, and the cutting is distributed along the even circumferential of centre hole;The centre hole is connect by exhaust tube with vacuum plant.
Further, the vacuum means are set to vacuum pump.Multiple centre holes connect one or more by exhaust tube Vacuum plant, and threeway or four-way connection are configured on exhaust tube as needed.
The present invention compared with the existing technology, using the centre hole of existing mold dynamic model as outlet is vacuumized, by dynamic It installs vacuum extractor on mould additional, after injection molding molding supercharging, quickly air in mould cavity is taken out using vacuum extractor, this Sample can substantially reduce injection pressure, and plastic parts moulding is made to become easy from difficulty, and to improve production efficiency, reduction is produced into This, reduces the energy expenditure of machine.Due to the setting of cutting on the inner wall of centre hole so that exhaust is more smooth and is not easy to block up Plug, the various product defects caused by exhaust is bad are such as:The problems such as focal spot, gasification, is readily solved.The present invention is broadly applicable In the Shooting Technique of various products material, have many advantages, such as that formed product is easy, qualification rate is high.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention;
Fig. 2 is centre hole structural representation Fig. 1 of the present invention;
Fig. 3 is centre hole structural representation Fig. 2 of the present invention.
Specific implementation mode
Below with reference to attached drawing, the present invention is described in detail:
As shown in Figs. 1-3:
A kind of connecting line injection mold, including cover half 1, and the dynamic model 2 that is arranged on cover half 1 further include setting dynamic Centre hole 3 on mould 2 is provided with multiple cuttings 6, the section configuration of the cutting 6 in an axial direction on the inner wall of the centre hole 3 For triangle or semicircle, as Fig. 2 and and Fig. 3, and the cutting 6 is distributed along the even circumferential of centre hole 3;The centre hole 3 It is connect with vacuum plant 4 by exhaust tube 5.
The vacuum extractor 4 is vacuum pump.Multiple centre holes 3 connect one or more vacuum holding by exhaust tube 5 4 are set, and configures threeway or four-way connection on exhaust tube 5 as needed.
The present invention compared with the existing technology, using the centre hole of existing mold dynamic model as outlet is vacuumized, by dynamic It installs vacuum extractor on mould additional, after injection molding molding supercharging, quickly air in mould cavity is taken out using vacuum extractor, this Sample can substantially reduce injection pressure, and plastic parts moulding is made to become easy from difficulty, and to improve production efficiency, reduction is produced into This, reduces the energy expenditure of machine.Due to the setting of cutting on the inner wall of centre hole so that exhaust is more smooth and is not easy to block up Plug, the various product defects caused by exhaust is bad are such as:The problems such as focal spot, gasification, is readily solved.The present invention is broadly applicable In the Shooting Technique of various products material, have many advantages, such as that formed product is easy, qualification rate is high.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to preferred embodiment to this hair It is bright to be described in detail, it will be understood by those of ordinary skill in the art that, it can modify to technical scheme of the present invention Or equivalent replacement should all cover the claim in the present invention without departing from the objective and range of technical solution of the present invention In range.
