Abstract

The utility model relates to a filter in a flow channel of an injection die, comprising a positioning loop body, an electrical heating loop and a filter, wherein a groove is arranged at the central of the bottom of the positioning loop body, an annular groove is arranged by taking the groove as the center, the filter is placed in the groove of the positioning loop body, and the electrical heating loop is placed in the groove of the positioning loop body. The filter has simple and practical structure, can be taken as a series standard part of the injection die, thus solving the obstruction problem of the injection flow channel, improving the injection efficiency and saving the energy.

Description

A kind of injection mold runner filter

Technical field

The utility model relates to a kind of filter, specifically a kind of injection mold runner filter.

Background technology

Injection molding technology obtains very using widely in the finished product manufacturing of all trades and professions, its basic principle is to utilize the tube that shoots material of annotating the shape machine that thermoplastic is heated to molten condition, again vasopressing injection in the injection mold cavity through being condensed into goods, conventional injection mold all must have centring ring, and centring ring is the locating element that mould is connected with injection machine; The plastic passages that shoots material and form between tube outlet and the die feeding mouth in injection moulding, because special process requirement, relatively Shan is narrow for this runner, and block easily, work as especially in order to save cost, in the time of will reclaiming plastics and mix virgin material and use as raw material with certain proportion, obstructing problem is even more serious, and this also is present ubiquity and the urgent problem that solves.

The utility model content

In order to overcome the problems referred to above, the utility model provides a kind of injection mold runner filter, and this apparatus structure is simple, and is easy to make, can prevent the recurrent runner phenomenon that blocks in the injection moulding production.

The technical solution adopted in the utility model is: a kind of injection mold runner filter, comprise the centring ring body, and also include Electrothermal ring, filter; Described centring ring body bottom centre has groove, is that the center has annular groove with the groove; Described filter places in the groove of centring ring body, and described Electrothermal ring places in the annular groove of centring ring body.

Described filter is column structure, and vertically is provided with the filter opening of a plurality of perforations.

Further improvement of the utility model is: the filtration import on the described centring ring body is the funnel type structure, is positioned at the center, and links to each other with the filter opening of filter.

The utility model is simple in structure, has offered groove and the annular groove of placing filter core and heating circle on the basis of original conventional centring ring, makes very convenient; It utilizes filter core that the foreign material in the melting plastics are blocked, and does not allow it enter the TOP-TIP of mould; And utilize the controllability that heating is enclosed to be increased melting plastics temperature, and keep the steady temperature of melting plastics, overcoming because of filter core brings the melting plastic flow time increases the shortcoming of mobile minimizing etc.

Description of drawings

Fig. 1 is a three-dimensional sectional structure schematic diagram of the present utility model.

Among the figure: 1 is the centring ring body; 1-1 is a groove; 1-2 is an annular groove; 1-3 is import; 2 is Electrothermal ring; 3 is filter; 3-1 is a filter opening.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment 1, as shown in Figure 1: a kind of injection mold runner filter of the present utility model comprises that the cross section is the centring ring body 1 of " protruding " font structure, centring ring body 1 bottom centre has circular groove 1-1 and around the concentric annular groove 1-2 of groove, settles Electrothermal ring 2 in the annular groove 1-2; Placement filter device 3 in the groove 1-1; Filter 3 size shape and groove 1-1 are complementary, and are cylindrical-shaped structure, vertically are provided with the filter opening 3-1 of a plurality of perforations; The center of protruding on the centring ring body 1 is provided with the filtration import 1-3 that is the funnel type structure, described import 1-3 links to each other with a plurality of filter opening 3-1 of filter and forms passage, wherein, the filter opening pore diameter range is between 3～6 millimeters, Electrothermal ring 2 is put into cannelure and is lower than centring ring body 1 base plane, and the cross section of Electrothermal ring 2 is circular.

The utility model is simple in structure, practical, and the series standard part that can be used as injection mold uses, and result of use is good, and the obstructing problem that it has solved injection molding channel has improved injection moulding efficient, has saved the energy.

Claims

1. an injection mold runner filter comprises the centring ring body, it is characterized in that: also include Electrothermal ring, filter; Described centring ring body bottom centre has groove, is that the center has annular groove with the groove; Described filter places in the groove of centring ring body, and described Electrothermal ring places in the annular groove of centring ring body.
