Abstract
The invention discloses an injection chamber heating device for die-casting machines, which comprises an injection chamber arranged in a fixing die plate of a die casting machine and a sprue bushing arranged in an outer fixing die and an inner fixing die of a die, wherein a first heating sleeve is arranged on the periphery of the sprue bushing in a circling manner; and a second heating sleeve is arranged on the periphery of the injection chamber in a circling manner. Through the adoption of the first heating sleeve and the second heating sleeve to heat the sprue bushing and a charging barrel respectively, the injection chamber heating device for the die-casting machines guarantees the temperature, reduces temperature loss of the molten metal when entering into the injection chamber and the sprue bushing, avoids the molten metal solidifying quickly, and guarantees the product quality.
Description
Technical field
The present invention relates to a kind of die casting machine injection chamber heater, relate in particular to the die casting machine injection chamber heater for the light-duty alloy of die casting aluminium, magnesium alloy.
Background technology
The die cast product of light-duty alloy be with molten metal bath at a high speed, inject mold cavity, filling casting under the high pressure, and the process of crystallization and freezing moulding under high pressure, whole injection process be divided into low speed, at a high speed, three main processes of supercharging.At present, the material that injection chamber is used is SKD61, the thermal conductivity factor of material is 20W/mk, therefore injection chamber can cause the temperature losses (decline) of molten metal bath, the temperature that this just influences molten metal bath causes the partial melting metal to solidify earlier, and these coagulums enter mold cavity with the solution filling and solidify, can cause casting defects such as the decline of foundry goods mechanical performance, poor air-tightness, peeling, thereby influence product quality.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of die casting machine injection chamber heater, can effectively avoid the partial melting metal to solidify in advance in that die casting is indoor, guarantee product quality.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of die casting machine injection chamber heater, comprise the injection chamber of being located in the die casting machine solid plate, and be located at mould and decide external mold and mould and decide sprue bush in the internal mold, be arranged with first heating jacket at described sprue bush peripheral ring, be arranged with second heating jacket at described injection chamber peripheral ring.Like this, respectively sprue bush and barrel are heated by first heating jacket and second heating jacket, guarantee its temperature, reduce the loss of molten metal bath temperature in entering injection chamber and sprue bush the time, avoid the motlten metal rapid solidification, guarantee product quality.
As a further improvement on the present invention, also be provided with a temperature controller, this temperature controller is controlled the temperature of described first heating jacket and second heating jacket.
The invention has the beneficial effects as follows: simple in structure, easy to use, can keep injection chamber to assigned temperature as required, avoid the partial melting metal indoor too fast the solidifying of die casting, guarantee product quality, can promote die casting chamber service life simultaneously.
Description of drawings
Fig. 1 is structural representation of the present invention.
By reference to the accompanying drawings, make the following instructions:
Mould moves internal mold to 1---mould moves external mold 2---
Mould is decided external mold to 3---mould is decided internal mold 4---
5---die casting machine solid plate 6---die casting
7---sprue bush 8---injection chamber
9---pressing chamber mouth 10---, first heating jacket
11---second heating jacket 12---plunger
The specific embodiment
By reference to the accompanying drawings, the present invention is elaborated.
As shown in Figure 1, a kind of die casting machine injection chamber heater comprises the injection chamber of being located in the die casting machine solid plate 58, and is located at mould and decide external mold 4 and mould and decides the interior sprue bush 7 of internal mold 3, be arranged with first heating jacket 10 at the sprue bush peripheral ring, be arranged with second heating jacket 11 at the injection chamber peripheral ring.Like this, motlten metal is after pressure chamber mouth 9 chargings of injection chamber, advance charging by plunger 12, making motlten metal progressively enter into the moving adventitia 1 of mould, the moving inner membrance 2 of mould, mould from injection chamber decide inner membrance 3 and mould and decide formation die casting 6 in the die cavity of adventitia 4 formation, therebetween, respectively sprue bush and injection chamber are heated by first heating jacket and second heating jacket, guarantee its temperature, reduce the loss of molten metal bath temperature in entering injection chamber and sprue bush the time, avoid motlten metal to form fragment, guarantee product quality.
Preferably, also be provided with a temperature controller on the heater of above-mentioned die casting machine injection chamber, this temperature controller is controlled the temperature of first heating jacket and second heating jacket, thereby can control injection chamber and sprue bush temperature more accurately.
Claims (2)
1. die casting machine injection chamber heater, comprise the injection chamber of being located in the die casting machine solid plate (5) (8), and be located at mould and decide external mold (4) and mould and decide sprue bush (7) in the internal mold (3), it is characterized in that: be arranged with first heating jacket (10) at described sprue bush peripheral ring, be arranged with second heating jacket (11) at described injection chamber peripheral ring.
2. die casting machine injection according to claim 1 chamber heater, it is characterized in that: also be provided with a temperature controller, this temperature controller is controlled the temperature of described first heating jacket and second heating jacket.
