Abstract

The utility model provides an improved structure of a hub casting die, and relates to the technical field of hubs. An upper die (1) is fixed on an upper die holder (1a), a lower die (2) is fixed on a lower die holder (2a); four males (4) are fixed on the upper die holder (1a) through screws, and four male slots (5) are molded in the lower die holder (2a); the lower part of each male (4) is inserted in each male slot (5); the lower part of each male (4) is in a pointed frustum shape, while each male slot (5) is in a frustum shape; the four males (4) are fixed on four corners of the square upper die holder (1a); four lateral dies (3) are respectively arranged in gaps enclosed by the four males (4). According to the improved structure, the upper and lower dies can be positioned more accurately, and the operation of a cooling gas pipeline connector can be more time-saving and labor-saving.

Description

Wheel hub casting mould structure-improved

Technical field:

The utility model relates to wheel hub production technical field, connects mouth more specifically to a kind of positioner and ventilation of wheel hub casting mould.

Background technology:

As shown in Figure 1, existing automotive hub casting mold is made up of patrix A1, counterdie A2 and four side form A3, patrix A1, counterdie A2 and four side form A3 form wheel hub casting mold cavity, convenient location aligns when allowing patrix A1 and counterdie A2 casting, on counterdie A2, form boss tenon A21, form tenon nest A11 on patrix A1, boss tenon A21 sleeve is in tenon nest A11, boss tenon A21 and tenon nest A11 are placed between the space of spoke of moulding wheel hub A4, and boss tenon A21 and tenon nest A11 are three.Its weak point is: 1, its boss tenon A21 and tenon nest A11 are all placed in the aluminium alloy melt of high temperature, often make the location of upper die and lower die that small deviation occurs, adopt the locating effect of the wheel hub casting mould upper die and lower die of this structure to need further to be improved, and easily produce plucking when the demoulding and affect product quality.2, on patrix A1 and counterdie A2, all form cooling duct, the cold gas pipe joint of cooling duct adopts the pipe joint of turn-knob bolt connection type, operating personnel need can allow cold gas pipeline connect with the moving cold gas pipe joint of hand-screw in the course of the work, and very effort of operation, also loses time like this.

Utility model content:

The purpose of this utility model is exactly the deficiency for prior art, and a kind of wheel hub casting mould structure-improved is provided, and its upper die and lower die location is more accurate, has improved product casting plucking phenomenon, and cold gas pipe joint operation is more time saving and energy saving.

Technology solution of the present utility model is as follows:

Wheel hub casting mould structure-improved, comprise upper die and lower die and four side forms, patrix is fixed on upper bolster, and counterdie is fixed on die shoe, on upper bolster, is fixed with four inserting columns by screw, on die shoe, form four inserting column recesses, the bottom sleeve of inserting column is in inserting column recess, and the bottom of inserting column is sharp frustum, and inserting column recess is frustum, four inserting columns are fixed on four angles into the upper bolster of square body, and four side forms are placed in respectively the gap that four inserting columns surround.

The cold gas pipe joint of described upper die and lower die is push type clamping pipe joint, and described push type clamping pipe joint is the pipe joint described in application number 201210271931.6 or application number 200820086195.6 patent documents.

The beneficial effects of the utility model are:

Its upper die and lower die location is more accurate, has improved product casting plucking phenomenon, and cold gas pipe joint operation is more time saving and energy saving.

Brief description of the drawings:

Fig. 1 is the structural representation of prior art;

Fig. 2 is structural representation of the present utility model.

In figure: 1, patrix; 1a, upper bolster; 2, counterdie; 2a, die shoe; 3, side form; 4, inserting column; 5, inserting column recess; 6, cold gas pipe joint.

Detailed description of the invention:

Embodiment: as shown in Figure 2, wheel hub casting mould structure-improved, comprise patrix 1, counterdie 2 and four side forms 3, patrix 1 is fixed on upper bolster 1a, counterdie 2 is fixed on die shoe 2a, upper bolster 1a is upper is fixed with four inserting columns 4 by screw, on die shoe 2a, form four inserting column recesses 5, the bottom sleeve of inserting column 4 is in inserting column recess 5, the bottom of inserting column 4 is sharp frustum, inserting column recess 5 is frustum, and four inserting columns 4 are fixed on four angles into the upper bolster 1a of square body, and four side forms 3 are placed in respectively the gap that four inserting columns 4 surround.

The cold gas pipe joint 6 of described patrix 1 and counterdie 2 is push type clamping pipe joint, and described push type clamping pipe joint is the pipe joint described in application number 201210271931.6 or application number 200820086195.6 patent documents.

Operation principle: because the location of patrix 1 and counterdie 2 adopts the inserting column 4 and the inserting column recess 5 that are placed in patrix 1 and counterdie 2 outsides, inserting column 4 and inserting column recess 5 are not subject to the impact of aluminium alloy melt high temperature and make upper die and lower die location accurate not like this, so the location of the utility model upper die and lower die is more accurate, improve product casting plucking phenomenon.

Owing to being fixed with four inserting columns 4 by screw on upper bolster 1a, and wheel hub casting mould when work, four side forms 3 are under the promotion of cylinder, to form wheel hub casting mold cavity with patrix 1 and counterdie 2 along track, so four side forms 3 are placed in respectively the gap that four inserting columns 4 surround, are convenient to four side forms and separate and combination with counterdie 2 with patrix 1 along track rectilinear motion.

Change turn-knob bolt connection type pipe joint in prior art into push type clamping pipe joint, cold gas pipe joint operation is more time saving and energy saving like this.
