Abstract
The utility model discloses a rubber lug mould, include: runner plate and be located runner plate below and with runner plate complex well when the compound die, the runner plate has the glue way groove and is located the pressure-bearing surface in glue way groove outside, wherein: the outer contour shape of the pressure bearing surface is square. The utility model discloses a change the pressure-bearing face into square structure by preceding radiation strip to can effectively prevent the emergence of excessive gluey phenomenon.
Description
Technical Field
The utility model relates to the technical field of mold, especially, relate to a rubber lug mould.
Background
In order to improve the stability of the quality of the lifting lug product and meet the requirement of maximum shift production efficiency, a large template with the specification of 700 x 700 is generally adopted for designing a mold for rubber lifting lug products with large annual demand and key customers. Because the injection process is adopted for injecting materials, the material running groove on the material channel plate needs to bear large injection pressure, and the sealing glue on the flow channel plate needs to be well designed. The existing material channel design adopts a glue material groove with the periphery extending for 5mm as a pressure bearing surface (such as a glue material groove a and a pressure bearing surface b in figure 1); however, the design concentrates the pressure on the middle position of the mold, and the pressure around the mold plate is not enough to press the mold plate to be dead along with the injection of the rubber material under high pressure, so that the rubber material overflows, the mold cavity cannot be filled instantly, and the product is short of material and cannot be molded.
SUMMERY OF THE UTILITY MODEL
For solving the technical problem who exists among the background art, the utility model provides a rubber lug mould.
The utility model provides a pair of rubber lug mould, include: runner plate and be located runner plate below and with runner plate complex well when the compound die, the runner plate has the glue way groove and is located the pressure-bearing surface in glue way groove outside, wherein:
the outer contour shape of the pressure bearing surface is square.
Preferably, the middle mold is provided with a cavity which is through up and down, and a milling groove is formed in the end face, matched with the runner plate, of the middle mold and located on the outer side of the cavity.
Preferably, the depth of the milled groove is 0.5 mm.
Preferably, the distance between the milling groove and the cavity is 5 mm.
Preferably, the runner plate is further provided with a glue injection hole communicated with the glue channel groove, and the glue injection hole is positioned on the central point of the pressure bearing surface.
The utility model discloses in, through changing the pressure-bearing face into square structure by preceding radiation strip to can effectively prevent the emergence of excessive gluey phenomenon.

Detailed Description
The technical solution of the present invention will be described in detail by the following embodiments.
As shown in fig. 1 to 4, fig. 1 is a schematic structural view of a conventional flow field plate; FIG. 2 is a schematic structural diagram of a prior art middle mold; fig. 3 is a schematic structural view of the runner plate in the rubber lug mold provided by the present invention; fig. 4 is a schematic structural view of the middle die in the rubber lug die provided by the present invention; fig. 5 is the utility model provides a structural schematic diagram of rubber lug mould compound die during state.
Referring to fig. 3-5, the utility model provides a rubber lug mould, include: runner plate 1 and well mould 2 that is located runner plate 1 below and cooperates with runner plate 1 when the compound die, runner plate 1 has glue channel 11 and is located the pressure-bearing surface 12 of glue channel 11 outside, wherein:
In addition, the middle mold 2 is provided with a cavity 21 which is through up and down, and a milling groove 22 is formed in the end face, matched with the runner plate 1, of the middle mold 2 and located on the outer side of the cavity 21, so that the stress area of the outer side of the cavity 21 is reduced, the pressure is increased, the product tearing groove is thin, and fins are easily removed. Therefore, the problems that in the prior art, the stress area is synchronously enlarged due to the increase of the template, the pressure applied to the unit area is reduced, the edge is thickened and is not easy to clear, and the edge removing efficiency is influenced are solved. The arrangement of the milling groove 22 greatly improves the product qualification rate and the trimming efficiency.
In this embodiment, the depth of the milling groove 22 is 0.5 mm. The distance between the milling groove 22 and the cavity 21 is 5 mm.
In this embodiment, the runner plate 1 further has a glue injection hole communicated with the glue channel groove 11, and the glue injection hole is located at the central point of the pressure-bearing surface 12.
To sum up, the utility model provides high the line production efficiency of product has solved the injection large mould and has overflowed a difficult problem of gluing at the pan feeding in-process. In addition, in the embodiment, the bearing surface and the milling groove are milled, and the subsequent processing capacity of the product can be greatly improved and the processing qualified rate is improved by the aid of the milling mode.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
