Abstract
The invention relates to a sliding block of a subsurface gating mold, which comprises a sliding block body and at least one subsurface pouring pore channel, wherein the sliding block body has a parting surface provided with a forming groove matched with an injection molded product and a branch flow channel for pouring; the inlet of the subsurface pouring pore channel is arranged at the end of the branch flow channel; and the outlet of the subsurface pouring pore channel is arranged on the inner wall of the forming groove. Compared with the prior art, the sliding block on which a pouring system is arranged as a subsurface pouring pore simplifies the structure of the mold, allows for automatic injection, saves a post working processor for eliminating a pouring opening during the shooting of plastic pieces, improves production capacity and reduces manufacturing cost.
Description
Technical field
The present invention relates to the injection mold of small-sized plastic cement products, particularly relate to latent pouring die slide block.
Background technology
Small-sized plastic parts such as present household electrical appliance, automotive connector, mobile phone, computer, because the structure that the plastic cement products design needs is special, need during injection mold plastic parts is taken shape on the slide block in design, the running gate system of selecting this moment is arranged on usually on the interior die joint of two slide blocks and makees the flat cast gate 8 of side.As shown in Figure 1, open mould after injection moulding is finished, slide block 1 is along guide rail movement, and slide block 1 is with after plastic cement products 7 separates, and stub bar 6 is connected together with plastic cement products 7, need do stub bar and repair except that operation, has increased cost of labor.
Summary of the invention
Technical problem to be solved by this invention is exactly that a kind of simple in structure, latent pouring die slide block that cost is low is provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions: latent pouring die slide block, comprise the slide block body, described slide block body has a die joint, this die joint be provided with one with the suitable forming tank of injecting products, described die joint is provided with cast and uses the tributary runner, it is characterized in that, also comprises at least one submarine cast duct, the inlet in described submarine cast duct is located at the end of tributary runner, and its outlet is located on the inwall of forming tank.
Described submarine cast duct is extended on the forming tank inwall adjacent with the tributary flow field end by the tributary flow field end, constitutes an oblique duct.
Described submarine cast duct is a bellmouth, and the internal diameter in this duct successively decreases from inlet to outlet.
Compared with prior art, the present invention is arranged on running gate system and does the submarine funnel on the slide block, has simplified mould structure, injection moulding can realize automated production when producing, exempt the later process of rejecting cast gate when beer goes out plastic, improved production capacity, reduced cost of manufacture.
Description of drawings
Fig. 1 is the existing structural representation that advances to water the injection moulding slide block;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, latent pouring die slide block, comprise slide block body 1, described slide block body 1 has a die joint 2, this die joint 2 be provided with one with the suitable forming tank 3 of injecting products, described die joint 2 is provided with cast with tributary runner 4, it is characterized in that, also comprise at least one submarine cast duct 5, the inlet in described submarine cast duct 5 is located at the end of tributary runner 4, and its outlet is located on the inwall of forming tank 3.
Described submarine cast duct 5 is extended on the forming tank inwall adjacent with the tributary flow field end by the tributary flow field end, constitutes an oblique duct; Described submarine cast duct 5 is a bellmouth, and the internal diameter in this duct successively decreases from inlet to outlet.
Open mould after injection moulding is finished, slide block 1 is along guide rail movement, and the cut-out point of the funnel of hiding on the slide block 1 (exit in submarine cast duct) separates stub bar 6 automatically with plastic cement products 7, need not to do stub bar and rejects operation.
