Abstract
The utility model discloses an injection mould with submarine gates, which comprises an upper fixed plate, a lower fixed plate, a female mould, a male mould, a female mould kernel and an ejecting mechanism. The female mould is fixedly connected with the lower side of the upper fixed plate, the male mould is fixedly connected with the upper side of the lower fixed plate, a female kernel of the female mould and a male kernel of the male mould are attached to form a molding surface, a closed cavity in a regular shape is formed between the female kernel and the male kernel, and the ejecting mechanism is arranged in the female mould and comprises an ingate system of at least one ingate. A submarine gate is formed on the forming surface of the tail end of each ingate, and is connected with the closed cavity. The submarine gates of the injection mould are used for replacing side gates, so that secondary processing is omitted due to the fact that no gates are reserved after moulding of plastic products, labor for production of the plastic products is saved, processing procedures and cost for the plastic products are reduced while production cycle thereof is shortened. Accordingly, production efficiency of the plastic products is improved.
Description
Technical field
The utility model relates to a kind of injection mold, especially relates to a kind of injection mold with latent cast gate.
Background technology
Mould is an indispensable important tool in the injection mo(u)lding.Injection mo(u)lding is that the plastic material with the hot melt attitude injects the airtight die cavity that has required form in the mould at a high speed, treats the plastic material cooling curing, opens mould the plastic cement products that solidifies is ejected, to obtain the processing method of shaped article.The moulding expense is low because the injection mo(u)lding processing method has, molding cycle is short, forming process is simple and be easy to the complicated characteristics such as plastic cement products of forming shape, therefore uses very extensive in the plastic cement products application.
Existing plastic mould generally all includes the male model plate, caster and die etc., and die is mounted between male model plate and the caster, is provided with the airtight die cavity of goods in the die.Generally can in male model benevolence, offer the side gate that flows to the parallel top outgoing direction that makes hot melt attitude plastic material.The plastic material of hot melt attitude gets into this airtight die cavity from running channel through this side gate.
Yet the plastic cement products of using the injection mold moulding of this prior art is still connecting side gate.Because side gate is not the part of this plastic cement products, therefore, in subsequent handling, also must excise by hand or other plant equipment are carried out this side gate of secondary operations excision.But no matter be manual or use other plant equipment and carry out this side gate of secondary operations excision, all can waste the manpower that plastic cement products is produced, increase plastic cement products manufacturing procedure and cost, prolong the plastic cement products production cycle, thereby reduce plastic cement products production efficiency.
The utility model content
The utility model proposes a kind of injection mold with latent cast gate, solves existing injection mold because of using side gate, causes there is the low technical problem of production efficiency in the plastic cement products secondary operations.
The utility model adopts following technical scheme to realize: a kind of injection mold with latent cast gate, and it comprises: upper mounted plate; Bottom plate; Be fixedly connected on the master mold of upper mounted plate downside; Be fixedly connected on the male model of bottom plate upper side; The male model benevolence of the mother module core of master mold and male model is fitted and is arranged to a molded surface, and formation one has the airtight die cavity of solid shape between mother module core and the male model benevolence; Be arranged on ejecting mechanism in the master mold, comprise the ingate system of at least one ingate; The end of every ingate forms a latent cast gate at molded surface, and this latent cast gate connects airtight die cavity.
In a preferred embodiment, airtight die cavity comprises the first airtight die cavity and the second airtight die cavity that independently is provided with and is used for a plastic cement products of difference moulding; The ingate system comprises first ingate and second ingate; The end of first ingate forms one first cast gate of diving at molded surface; This first latent cast gate connects the first airtight die cavity; The end of second ingate forms one second cast gate of diving at molded surface, and this second latent cast gate connects the second airtight die cavity.
Compared with prior art; The injection mold that the utility model proposes adopts the cast gate of diving to replace side gate; Because of there not being residual cast gate,, thereby practiced thrift the manpower that plastic cement products is produced after the plastic cement products moulding so need not secondary operations; Reduce plastic cement products manufacturing procedure and cost, shortened the plastic cement products production cycle.Thereby improved plastic cement products production efficiency.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model;
Fig. 2 and Fig. 3 are respectively the enlarged diagrams of A among Fig. 1, B part.
The specific embodiment
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, the injection mold that the utility model proposes comprises: upper mounted plate 11; Bottom plate 12; Be fixedly connected on the master mold (being cover half or front mould again) 13 of upper mounted plate 11 downsides; Be fixedly connected on the male model (being dynamic model or back mould again) 14 of bottom plate 12 upper sides; Master mold 13 has mother module core 131; Male model 14 has male model benevolence 141; And mother module core 131 is fitted with male model benevolence 141 and is arranged to a molded surface, and formation one has the airtight die cavity (comprising the first airtight die cavity 171 and the second airtight die cavity 172) of solid shape between mother module core 131 and the male model benevolence 141; Be arranged on the ejecting mechanism 15 in the master mold 13, this ejecting mechanism 15 comprises some thimbles, and a wherein end of every thimble is fixedly installed on the master mold 13, and another end portion is passed master mold 13 arrival molded surfaces; Be arranged on the ingate system in the master mold 13, the ingate system comprises first ingate 161 that connects the first airtight die cavity 171, connects second ingate 162 of the second airtight die cavity 172.
On molded surface; The end of first ingate 161 forms one first cast gate (cast gate of submarine) 1611 of diving; Through this first dive cast gate 1611 be connected the first airtight die cavity 171, the plastic cement of hot melt is injected into the first airtight die cavity 171 through first ingate 161 from the first latent cast gate 1611 by injection machine under certain pressure.
Same; On molded surface; The end of second ingate 162 forms one second cast gate (cast gate of submarine) 1621 of diving; Through this second dive cast gate 1621 be connected the second airtight die cavity 172, the plastic cement of hot melt is injected into the second airtight die cavity 172 through second ingate 162 from the second latent cast gate 1621 by injection machine under certain pressure.
Above true example is that example is explained with 2 plastic cement products of one-shot forming in the airtight die cavity.Certainly; According to actual needs; Airtight die cavity in the injection mold can be arranged to 1 product of one-shot forming or the product more than 2; Corresponding, the ingate system need be provided with many ingates, and each bar ingate connects the hermetic type cavity segment of a plastic cement products of moulding in the airtight die cavity respectively through the latent cast gate of end.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
