Description

Automobile sealing element die structure

Technical Field

The utility model relates to an automobile sealing element mould structure belongs to automobile sealing element mould and makes technical field.

Background

The existing mold structure for manufacturing the mold of the automobile sealing element comprises an extrusion mold template and a flow distribution plate, as shown in fig. 1 and 2, a mold core is fixed on the flow distribution plate by a U-shaped bracket, as shown in fig. 3, the mold core passes through the flow distribution plate and then is produced into a product by the extrusion mold template; the designed mould only has one mould plate, when the mould plate is moulded, the mould core glue output quantity is influenced by the glue outlet and the glue output speed, so that the moulded product is difficult to meet the product requirement, the designed and processed mould plate is difficult to adjust on line according to the actual mould output result, the design method has high requirement on the special industry level of the mould design engineer, the mould is difficult to adjust on line, and the mould cost and the debugging cost are increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is how to realize the real-time adjustment that the template appeared.

In order to solve the technical problem, the technical scheme of the utility model is to provide an automobile sealing element mould structure, which is characterized by comprising an extrusion die splitter plate, an extrusion die demoulding plate and an extrusion die pressure equalizing plate matched with the extrusion die demoulding plate, wherein a conical hole for a core to pass through is arranged in the extrusion die splitter plate; the extrusion die is characterized in that a mold outlet corresponding to a product is formed in the middle of the extrusion die mold outlet plate, a protrusion matched with the mold outlet is arranged at a position corresponding to the extrusion die pressure equalizing plate, the extrusion die pressure equalizing plate and the extrusion die mold outlet plate are assembled in a working state, the protrusion is located in the mold outlet, a cavity is formed by a gap between the protrusion and the mold outlet, and a plurality of glue outlets used for adjusting glue outlet amount are formed in the periphery of the protrusion and the protrusion on the extrusion die pressure equalizing plate.

Preferably, the size of the glue outlet is the smallest in the initial state, and the size of the glue outlet is gradually enlarged according to the deviation between the actual extruded product and the designed product until the actual extruded product meets the design requirement of the product.

The utility model discloses the advantage is in convenient online debugging, and the die cavity goes out to glue the size accessible adjustment extrusion die equalizer plate of volume and goes out to glue mouthful control, avoids design and modification many times, practices thrift design and manufacturing cost.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

Examples

This embodiment is shown in fig. 4-8, and includes an extrusion die manifold, an extrusion die match plate, and an extrusion die pressure equalizer designed to match with the extrusion die match plate: the extrusion die flow distribution plate is internally provided with a conical hole for a core (generally made of rubber materials) to pass through, a forming hole corresponding to a product is reserved in the middle of the extrusion die forming plate, a protrusion matched with the forming hole is arranged at a position corresponding to the extrusion die pressure equalizing plate, the extrusion die pressure equalizing plate and the extrusion die forming plate are assembled under a working state, the protrusion is positioned in the forming hole, a cavity is formed by a gap between the protrusion and the forming hole, a plurality of glue outlets 1 with sizes adjusted in real time according to actual forming structures are reserved on the protrusion and the protrusion periphery of the extrusion die pressure equalizing plate, and the glue outlets 1 are processed to be the minimum under an initial state.

The utility model discloses mould structure's working process: after the extrusion die flow distribution plate, the extrusion die pressure equalizing plate and the extrusion die molded plate are assembled, the core enters the glue outlet 1 of the extrusion die pressure equalizing plate through the inner taper hole of the extrusion die flow distribution plate, the core enters the mold cavity after being extruded from the glue outlet 1, the mold cavity generates a product from the glue outlet after passing, the glue outlet 1 is in a minimum state at the moment, the glue outlet 1 is enlarged according to the deviation of the size of the actual extruded product at the moment relative to the size of the designed product, the process is repeated to enlarge the glue outlet 1, and the product reaches the design requirement of the product until the actual extruded product.

The utility model discloses an extrusion die equalizer plate and extrusion die flow distribution plate's bell mouth, on the one hand removed the influence of using U-shaped support fixed core to the product among the prior art mutually, on the other hand is at the in-process of debugging extrusion product, through the design of extrusion die equalizer plate's play jiao kou 1, only need to go out jiao kou 1 size according to actual product deviation adjustment, whole process need not modify extrusion die play template, also need not modify the mould parts such as the arch of extrusion die equalizer plate, design and modification many times have been avoided, design and manufacturing cost have been practiced thrift.
