Compared with the prior art, the utility model discloses set up the difference in height between mould template and die cavity boss, set up the slot moreover, this two points combine together and to let the pressure of mould more concentrate on the die cavity boss, and unnecessary material can overflow to the ditch inslot to make the product overlap thinner, change the trimming work of back process.
Description
Technical Field
The utility model belongs to rubber compression molding field, concretely relates to rubber compression molding mould that pressure is concentrated more.
Background
Rubber molding is a process of pressing a preform into a mold cavity by various rubber molding machines. And then the rubber material is subjected to chemical reaction (molecules are crosslinked into a net shape from a linear shape) at a specific temperature and pressure for a period of time, so that a product with applicable properties is prepared. Wherein, the mould structure plays decisive effect to the shaping effect, and in compression molding process, uneven or the pressure is not concentrated and can cause the substandard product that the product lacked the material usually, and the probability that this problem appears in the product of mould geometry central point especially is bigger. In order to solve the problem, the conventional method is to increase the weight of the material, so that the waste of the raw material is caused, the thickness of the flash is increased while the weight of the material is increased, the difficulty is brought to the subsequent trimming work, and meanwhile, the size of the product at the position close to the center is smaller than that of the product at the periphery, so that the product is unstable.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the rubber compression molding die with more concentrated pressure is provided, so that the die pressure can be more concentrated under the same condition, fewer raw materials are used, the product size is more stable, and trimming is easier.
The rubber compression molding die with more concentrated pressure comprises a die template, wherein the upper end of the die template is fixedly connected with a die cavity boss, a plurality of die cavities are arranged on the die cavity boss, the upper surface position of the die cavity boss is higher than that of the die template, and a circle of groove is formed in the joint of the die cavity boss and the die template or on the die cavity boss or on the die template.
The rubber compression molding die with more concentrated pressure is characterized in that the die template and the cavity boss are of an integrated structure.
The rubber compression molding die with more concentrated pressure has the advantage that the height difference between the upper surface of the cavity boss and the upper surface of the die template is 0.05-0.10 mm.
The rubber compression molding die with more concentrated pressure has the advantage that the height difference between the upper surface of the cavity boss and the upper surface of the die template is 0.07 mm.
The rubber compression molding die with more concentrated pressure is characterized in that the width of the groove is 2-4 mm, and the depth of the groove is 1-2 mm.
The rubber compression molding die with more concentrated pressure is characterized in that the width of the groove is 3mm, and the depth of the groove is 1.5 mm.
Compared with the prior art, the utility model discloses set up the difference in height between mould template and die cavity boss, set up the slot moreover, this two points combine together and to let the pressure of mould more concentrate on the die cavity boss, and unnecessary material can overflow to the ditch inslot to make the product overlap thinner, change the trimming work of back process.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a left side view structure diagram of the present invention.
In the figure: 1 mould template, 2 die cavity bosses, 200 mould die cavities and 3 grooves.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, a rubber compression molding mould that pressure is concentrated more, including mould template 1, mould template 1 is the lower bolster, 1 upper end fixed connection die cavity boss 2 of mould template, be covered with mould die cavity 200 on the die cavity boss 2, the shape of mould die cavity 200 is decided according to the processing demand, the utility model discloses the processing that uses O shape circle is the example. The upper surfaces of the cavity boss 2 and the die template 1 are both planes, the two planes are also called parting planes, the upper surface position of the cavity boss 2 is higher than the upper surface position of the die template 1, and the height difference between the cavity boss 2 and the die template is 0.05mm-0.10mm, preferably 0.07 mm.
The utility model discloses in, round slot 3 is seted up with the junction of mould template 1 to die cavity boss 2, slot 3 encircles 2 bottom outer margins of die cavity boss, the width of slot 3 is 2mm-4mm, is preferably 3mm, and the degree of depth is 1mm-2mm, is preferably 1.5mm, and wherein, "round" only indicates that slot 3 encircles the setting of die cavity boss 2, and is not to the restriction of its number. In addition, the groove 3 may be formed on the outer edge of the upper surface of the cavity boss 2 or on the mold platen 1.
The utility model discloses in, mould template 1 and die cavity boss 2 structure as an organic whole, also can be through the components of a whole that can function independently structure of screwed connection.
The utility model discloses set up the difference in height between mould template and die cavity boss, and set up the slot in both combination departments, this two point combination can let the pressure of mould more concentrate on the die cavity boss, and unnecessary material can overflow to the ditch inslot to make the product overlap thinner, change the trimming work of back process. The utility model discloses can use raw materials still less to accomplish processing, more be difficult for producing the substandard product that lacks the material moreover, the product size is more stable.
Finally, it should be noted that: for those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made (e.g., the height difference, the position of the boundary of the height difference region, which can be designed on a template or a plurality of templates), the size, depth and shape of the groove, and the position of the groove can be different from the boundary, such as in the cavity boss or in the mold template, which all fall within the protection scope of the present invention.
