Abstract

The utility model discloses a die-casting die which comprises an upper support plate, a fixed die plate, a fixed die kernel, a movable die kernel and a movable die plate, wherein the upper support plate, the fixed die plate, the fixed die kernel, the movable die kernel and the movable die plate are placed in sequence from top to bottom, and a mold cavity is formed by combining of the fixed die kernel and the movable die kernel. A sprue is arranged in the middle position of the upper support plate, wherein the middle portion is close to the side end of the upper support plate, and a pouring channel communicated with the sprue is placed inside the mold cavity. Eight molding grooves which are placed in two rows symmetrically are arranged on two sides of the pouring channel, and each molding groove is communicated with the pouring channel through embranchment channels. A loose core is respectively placed on outer side of each row of the molding grooves, and two loose cores are respectively connected with a sliding block loose core mechanism. According the die-casting die, discharging is carried out after a railway furcation connector rotates 90 degrees, and core-pulling of the two side faces is not needed to be carried out after the rotation of the railway furcation connector, so that rejection rate is effectively reduced.

Description

A kind of die casting

Technical field

The utility model relates to a kind of mould, particularly a kind of die casting.

Background technology

Shown in Fig. 1 and 2 is a kind of railway fork-shaped connector, and it comprises connecting hole A2, two forks pin A3 and A3', every draw-in groove A1 that the fork pin is provided with to engage.

Generally can be with product B 1, B2, B3 and B4 traverse when discharge, namely connecting hole A2 and draw-in groove A1 be in the side, and adopt that glue is advanced in the side, a mould goes out four design, and corresponding mold cavity is as shown in Figure 3.But the position of connecting hole A2 and draw-in groove A1 is nearer, can only realize the demoulding of connecting hole A2 in limited die space, and draw-in groove A1 need carry out forced stripper mechanism, but this measure meeting causes draw-in groove A1 distortion, causes the scrappage of product to increase.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of die casting, to realize reducing the purpose of product rejection rate.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of die casting comprises the mounting plate, solid plate, fixed mold core, mavable module core and the moving platen that set gradually from top to bottom, and described fixed mold core and described mavable module core are combined the formation die cavity; Proximal medium position is provided with cast gate on the described mounting plate, be provided with a running channel that links to each other with described cast gate in the described die cavity, the bilateral symmetry of described running channel is provided with two rows totally eight forming tank, and described each forming tank links to each other with described running channel by branch flow passage; The outside of the described forming tank of every row is respectively arranged with one and looses core, and described loosing core is connected with respectively a sliding block core-pulling mechanism.

Preferably, described sliding block core-pulling mechanism comprises slide block and brace; Described slide block and described loosing core fix, and described slide block is positioned at the upper end of described moving platen, and are flexibly connected with described moving platen; Described brace is fixed on described cover half and pulls, and its lower end is passed in the described slide block.

By technique scheme, the die casting that the utility model provides is by with discharge again behind the railway fork-shaped connector 90-degree rotation.After the rotation, connecting hole A2 and draw-in groove A1 are positioned on the vertical position, loose core in the side that need not to carry out again this two place, only need to loose core with the side of loosing core to pitch pin of an integral body get final product, have prevented that not only draw-in groove A1 is out of shape but also structure is simpler.Because postrotational railway fork-shaped connector area in the horizontal is less, so be provided with eight forming tank in limited die cavity, has realized that a mould goes out eight, has improved production efficiency effectively.

Description of drawings

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.

The utility model provides a kind of die casting (with reference to Fig. 4), comprising:

The mounting plate C2 that sets gradually from top to bottom, solid plate C4, fixed mold core C3, mavable module core D1 and moving platen D2.

Fixed mold core C3 and mavable module core D1 are combined the formation die cavity.

Referring to Fig. 5, the upper proximal medium position of mounting plate C2 is provided with cast gate C1, is provided with a running channel H1 who links to each other with cast gate C1 in the die cavity.

The bilateral symmetry of running channel H1 is provided with two rows totally eight forming tank K, and each forming tank K links to each other with running channel H1 by branch flow passage H2.

The outside of every row's forming tank K is respectively arranged with the C7 of loosing core, a C7', and the C7C7 of loosing core, C7' are connected with respectively a sliding block core-pulling mechanism.

Sliding block core-pulling mechanism comprises slide block and brace.Slide block C6, C6' and the C7 of loosing core, C7' fix, and slide block C6, C6' are positioned at the upper end of moving platen D2, and are flexibly connected with moving platen D2; Brace C5 is fixed on cover half and pulls on the C4, and its lower end is passed in the slide block.

Die sinking process of the present utility model is as follows:

Dynamic model retreats, and brace forces slide block to be decorporated to the direction away from product, and the C7 of loosing core, C7' are taken out of together.

Then, beating bar D3 advances product is released from mavable module core.

At last, product falls under action of gravitation.

The die casting that the utility model provides is by with discharge again behind the railway fork-shaped connector 90-degree rotation.After the rotation, connecting hole A2 and draw-in groove A1 are positioned on the vertical position, loose core in the side that need not to carry out again this two place, only need to loose core with the side of loosing core to pitch pin of an integral body to get final product, not only prevented draw-in groove A1 distortion, reduced the rate of offering, and structure is simpler.

Because postrotational railway fork-shaped connector area in the horizontal is less, so be provided with eight forming tank in limited die cavity, has realized that a mould goes out eight, has improved production efficiency effectively.

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, in other embodiments realization.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.
