Abstract

The utility model discloses a semi-hot runner system which relates to hot runner systems. The semi-hot runner system comprises a temperature controller, and a hot runner plate with a runner therein, wherein a heater and a thermoelectric couple are arranged on the hot runner plate, the temperature controller is respectively connected with the heater and the thermoelectric couple, the semi-hot runner system further comprises a semi-hot nozzle which is not equipped with an electric heating device, the semi-hot nozzle comprises an inner pin, the inner pin is connected with the hot runner plate and provided with a corresponding runner, and the semi-hot nozzle can be connected with a product directly and also can be connected with the product after passing through a cool runner. The semi-hot runner system can solve the problems in a complete hot runner system such as complex structure, high failure rate, server requirements for die processing accuracy, difficulty in maintenance, high cost, difficulty population, and difficulty in application to a die with a smaller center distance at a pouring gate.

Description

A kind of half TOP-TIP

Technical field

The utility model relates to a kind of TOP-TIP, relates in particular to a kind of half TOP-TIP.

Background technology

Present complete TOP-TIP, it mainly is made up of hot runner manifold, Re Zui, heater, attemperating unit.Each hot mouth all has independently heater and temperature controller.Its shortcoming is as follows: 1. complex structure, to Mould Machining required precision height; 2. hot mouth heater coil, thermocouple are easily aging, often can't be satisfactory on the stability, its main cause is the complicated electric heating structure of the hot mouth of TOP-TIP and the working environment of its hundreds of degree centigrade uninterrupted high temperature, and the hot mouth structure of TOP-TIP complexity, make its fault rate height, maintenance personal's professional skill is had higher requirement, and maintenance cost height, maintenance time is long, causes downtime long, thereby influences production efficiency and actual production capacity greatly; 3. for the complete TOP-TIP of multi-point mould, because each hot mouth all has independently heater, thermocouple, so number of electrical lines is various and complicated, the uncertain factor of installing in the wiring process will increase; 5. the mould that cast gate centre-to-centre spacing is too little is difficult to realize with complete TOP-TIP; 6. the TOP-TIP structure is multiple fully, costs an arm and a leg, and the price of TOP-TIP exceeds much than mould price usually, therefore is difficult to large tracts of land and promotes.

The utility model content

At above-mentioned prior art, the purpose of this utility model be to provide a kind of simple in structure, fault rate is low,, maintenance not high to the Mould Machining required precision easily, be applicable to mould and low price that cast gate centre-to-centre spacing is less, half TOP-TIP that is easy to promote.

To achieve these goals, the utility model adopts following technical scheme: a kind of half TOP-TIP, comprise that temperature controller, inside are provided with the hot runner manifold of runner, described hot runner manifold is provided with heater and thermocouple, temperature controller connects heater and thermocouple respectively, also comprise the Ban Rezui that is not provided with electric calorifie installation, described half hot mouth is made of interior pin, and interior pin is connected and is provided with the runner of correspondence with hot runner manifold.

As preferably, described half hot mouth also is provided with half hot muzzle outward.

As preferably, described in the outer surface of pin and half hot muzzle be provided with cannelure.

As preferably, the lower end of described half hot mouth is connected with cold runner.

As preferably, described half hot mouth and hot runner manifold are that the plane compresses and docks.

Compared with prior art, the utlity model has following advantage: not be used in existing hot mouth place electric heating systems such as heater and temperature controller all are set, but adopt half hot mouth structure to replace original hot mouth structure, the structure of reduced heat flow road system, the probability that reduces to break down, reduce maintenance difficulty and cost, shorten maintenance time; Can realize simultaneously that cast gate centre-to-centre spacing requires the hot runner mould of less mould to make; Only account for the 30%--50% of complete TOP-TIP on the price, greatly reduce die cost, the convenient popularization; Outer surface at interior pin and half hot muzzle is provided with cannelure, can reduce the contact area with mould, thereby reduce thermal loss, and it is that the plane compresses butt joint that half hot mouth is connected with hot runner manifold, can mend automatically like this and taste the change in size of bringing because of thermal expansion.

Fig. 1 is the structural representation of the utility model embodiment one;

Fig. 2 is the structural representation of the utility model embodiment two.

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples.

Embodiment one:

Referring to Fig. 1, a kind of half TOP-TIP, comprise temperature controller, inside is provided with the hot runner manifold 3 of runner 4, sprue bush 1 and supporting pad 2 in the setting of hot runner manifold 3 upper surfaces, be positioned at the solid plate 9 of hot runner manifold 3 belows, center pad 8 between solid plate 9 and hot runner manifold 3, described hot runner manifold 3 is provided with heater and thermocouple, temperature controller connects heater and thermocouple respectively, also comprise the Ban Rezui that docks and be not provided with electric calorifie installations such as heater and thermocouple with hot runner manifold 3 for the plane compresses, described half hot mouth is made up of interior pin 5 and half hot muzzle 6, half hot muzzle 6 mainly plays the interior pin 5 of protection and supports hot runner manifold 3, pin 5 is selected different material manufacturings for use according to the product material difference in described, as: the beryllium copper that thermal conductivity factor is very high, the high-speed steel of high-hardness, wearable etc., the interior pin 5 of present embodiment is made by the very high beryllium copper material of thermal conductivity factor, and the inside of interior pin 5 is provided with the runner 4 corresponding with hot runner manifold 3; The outer surface of pin 5 and half hot muzzle 6 is provided with cannelure in described, thereby cannelure is in order to reduce to reduce with the contact area of mould parts the loss of heat; The lower end of described half hot mouth is connected with cold runner 7, and half hot mouth is communicated with product by cold runner 7 again.

Embodiment two:

Referring to Fig. 2, a kind of half TOP-TIP, comprise temperature controller, inside is provided with the hot runner manifold 3 of runner 4, sprue bush 1 and supporting pad 2 in the setting of hot runner manifold 3 upper surfaces, be positioned at the solid plate 9 of hot runner manifold 3 belows, center pad 8 between solid plate 9 and hot runner manifold 3, described hot runner manifold 3 is provided with heater and thermocouple, temperature controller connects heater and thermocouple respectively, also comprise the Ban Rezui that docks and be not provided with electric calorifie installations such as heater and thermocouple with hot runner manifold 3 for the plane compresses, described half hot mouth is made up of interior pin 5 and half hot muzzle 6, half hot muzzle 6 mainly plays the interior pin 5 of protection and supports hot runner manifold 3, pin 5 is selected different material manufacturings for use according to the product material difference in described, as: the beryllium copper that thermal conductivity factor is very high, the high-speed steel of high-hardness, wearable etc., the interior pin 5 of present embodiment is made by the high-speed steel of high-hardness, wearable, and the inside of interior pin 5 is provided with the runner 4 corresponding with hot runner manifold 3; The outer surface of pin 5 and half hot muzzle 6 is provided with cannelure in described, thereby cannelure is in order to reduce to reduce with the contact area of mould parts the loss of heat; The lower end of described half hot mouth directly links to each other with product, and cold runner need not be passed through in the centre, can maximized economical with materials.
