Abstract
The utility model discloses a mold for the production of injection-molded parts. The mold is characterized in that: the mold is provided with a cavity, the cavity is provided with a gate, and the gate is positioned over the cavity. The mold has the following advantages: (1) the quality of the injection-molded parts is completely improved, the right sides of products are not broken, and the appearance inspection of the products is qualified; (2) the injection molding pressure is effectively improved during injection molding, and is regulated from 160mpa/cm2 to 108mpa/cm2, so that injection molding can be facilitated; (3) after the injection molding pressure is regulated, the actual shrinkage rate of plastic products is equal to the designed parameter, and all dimensions come up to standard after being measured; (4) the utility model can be applied into other molds, so that a large number of products can be automatically produced on an injection molding machine, and the mold does not need to be dived to the surface of the right side; (5) the balance of mold flow can be easily controlled by the runner direction, so that the sequence and pressure of the mold flow can be controlled by multi-cavity molds in a simple way later.
Description
Technical field
The utility model relates to a kind of moulding production mould.
Background technology
Be illustrated in figure 1 as a kind of moulding 1, it is provided with slot 2 in the side.Slot 2 is to be used to plug pcb board and to be provided with.According to the requirement that moulding 1 uses, slot 2 can only be arranged on position as shown in Figure 1.
The mould that uses in the moulding production comprises male model and master mold.Be provided with the die cavity identical between male model and the master mold with product structure.Die cavity is used to hold injection molding material.Behind the injection molding material cooling forming moulding.Be illustrated in figure 2 as the mould of producing moulding shown in Figure 1, it comprises master mold and the male model of being made up of slide block 31 and slide block 32 4.Slide block 31, slide block 32 lump together with male model 4 forms the die cavity (not shown).Cast gate 33 is communicated with die cavity.Injection molding material injects in the die cavity by cast gate 33, after the injection molding material cooling, and slide block 31, slide block 32 demouldings, product depanning then.
But mould shown in Figure 2 in use, and in the slide block demoulding in a flash, in the fracture of slot top, right side, product appearance has damage in various degree to product easily.Another shortcoming of this mould is to be difficult to injection moulding, and on the horizontal injection press of 120 tonnages, injection pressure has been adjusted becomes 160mpa/cm
2The time still can't break into this product.Use another weak point of this mould to be that injection pressure is excessive, easily cause this product washing shrinkage bad, according to early stage the design-calculated washing shrinkage can't be consistent with the washing shrinkage of actual product, cause the product design size to exceed standard.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of injection pressure little moulding production mould.
For achieving the above object, the utility model is achieved through the following technical solutions:
Moulding production mould is characterized in that described mould is provided with die cavity, and die cavity is provided with cast gate, and described cast gate is positioned at directly over the die cavity.
Preferably, described mould comprises male model and master mold, and described master mold is made up of two movable sliding blocks, and described cast gate is positioned on one of them slide block, and described one of them slide block is provided with runner, and described cast gate is communicated with runner and die cavity.
Preferably, described runner is the groove that is arranged on shoe surface.
Moulding production in the utility model has advantage with mould: 1. improved the moulding quality fully, and product right side non-cracking, and the product appearance detection is qualified.2. the injection pressure when effectively improving injection moulding, injection pressure is from 160mpa/cm
2Adjustment becomes 108mpa/cm
2, make things convenient for injection moulding.3. adjusted the product behind the injection pressure, the actual washing shrinkage of plastic cement products with when design parameter identical, all sizes are through all qualified after measuring.4. can be applied in other moulds, many products can be produced on injection machine automatically, the right side appearance need not to dive under water.5. the runner direction that walks is controlled the mould mobile equilibrium easily, and the multi-impression mold prodigiosin is simply controlled injection mould stream order and pressure after making.
Description of drawings
Fig. 1 is existing a kind of moulding structural representation.
Fig. 2 is for producing a kind of mould structure schematic diagram of the moulding among Fig. 1.
Fig. 3 is the mould part structural representation among Fig. 2.
Fig. 4 is the mould structure schematic diagram in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 4.Moulding production mould comprises male model and two slide blocks, only shows slide block 31 among the figure, and slide block 31 surfaces are provided with groove 36, and groove 36 is communicated with cast gate 34, and cast gate 34 is communicated with die cavity 35.Cast gate 34 is positioned at directly over the die cavity 35.Die cavity 35 among the figure only shows a part.Surround die cavity between slide block 31 and another slide block and male model are common.
During injection moulding, injection molding material flow to cast gate 34 from groove 36, injects die cavity 35 through cast gate 34.After the injection molding material cooling, the slide block depanning, product is depanning again.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
Claims (3)
1. moulding production mould is characterized in that, described mould is provided with die cavity, and die cavity is provided with cast gate, and described cast gate is positioned at directly over the die cavity.
2. moulding production mould according to claim 1, it is characterized in that, described mould comprises male model and master mold, described master mold is made up of two movable sliding blocks, described cast gate is positioned on one of them slide block, described one of them slide block is provided with runner, and described cast gate is communicated with runner and die cavity.
