Abstract
The utility model relates to the field of plastic moulds, in particular to an ejection delayed structure of a plastic mould, which comprises an ejector pin panel and an ejector pin baseplate, wherein the ejector pin panel and the ejector pin baseplate are fixedly connected, a product ejector rod is fixed on the ejector pin panel, one end of the product ejector rod penetrates through the ejector pin panel, the other end of the product ejector rod is fixed at the bottom of the ejector pin panel, the ejector pin panel is provided with a stub bar ejector rod, the middle of the stub bar ejector rod is provided with a step, the ejector pin panel and the ejector pin baseplate are provided with an interconnected groove, and the step is moved in the groove up and down. The ejection delayed structure of the plastic mould has the beneficial effects of having the advantage of latent feeding, and avoiding the defect that the cost of the common ejection delayed mechanism is increased, and the difficulty in processing the mould is never increased.
Description
Technical field
The utility model relates to the mould of plastics field, especially a kind of mould of plastics eject time-delay structure.
Background technology
Plastic product is after ejecting, and product connects together with stub bar usually, must be through after pruning, just can obtain final products, but in the pruning process as misoperation, damage product surface easily, the product high to some appearance requirement makes scrappage raise, and increased production cost.For addressing the above problem, generally take two kinds of methods, first kind is product take to hide charging design, product nature when die sinking separates with stub bar, and then ejects product; Second kind is to adopt to eject time-delay mechanism, also claims secondary ejecting mechanism, and product does not separate with stub bar when die sinking, and product just separates with stub bar in the process that ejects.The first method advantage is simple and practical, and effect is also fine, and in the structure of product does not support to hide charging, generally just takes second method, but there is increase Mould Machining difficulty in second method, increases the shortcoming of production cost.
Summary of the invention
Above-mentioned mould difficulty increases and the technical problem of cost rising in order to solve, and the utility model provides a kind of time-delay structure that ejects of simple and practical and economic a kind of mould of plastics.
The technical solution of the utility model is as follows:
A kind of mould of plastics eject time-delay structure, comprise thimble panel and Ejector Retainer Plate, described thimble panel and Ejector Retainer Plate are fixed together, be fixed with the product push rod on the described thimble panel, described product push rod one end penetrates the thimble panel, and the other end is fixed on thimble panel bottom, described thimble panel is provided with the stub bar push rod, be provided with step in the middle of the described stub bar push rod, described thimble panel and Ejector Retainer Plate have the groove of connection, and described step moves up and down in groove.
As preferably, described product push rod is T type shape, damage like this change more convenient.
Use the technical solution of the utility model, the advantage of the existing charging of hiding has also avoided generally ejecting the shortcoming that cost that time-delay mechanism brings increases, and the processing mold difficulty also increases.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model stub bar push rod.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As Fig. 1, shown in 2, a kind of mould of plastics eject time-delay structure, comprise thimble panel 7 and Ejector Retainer Plate 8, described thimble panel 7 and Ejector Retainer Plate 8 are fixed together, be fixed with product push rod 4 on the described thimble panel 7, described product push rod 4 one ends penetrate thimble panel 7, the other end is fixed on thimble panel 7 bottoms, described thimble panel 7 is provided with stub bar push rod 5, be provided with step 11 in the middle of the described stub bar push rod 5, described thimble panel 7 and Ejector Retainer Plate 8 have the groove 12 of connection, and described step 11 moves up and down in groove 12, and the height that belongs to the groove 12 of Ejector Retainer Plate 8 is considered as the time-delay height.
Described product push rod 4 is T type shape, and it is convenient to change.
During die sinking, after upper cores 1 and following die 2 separate, thimble panel 7 and Ejector Retainer Plate 8 move upward because of active force, product thimble 4 in the middle of being fixed on also moves upward together, stub bar thimble 5 is because there is the time-delay height bottom 9 with Ejector Retainer Plate 8 then, stub bar thimble 5 lower ends head on base plate 9, when so the height that moves upward by the time surpasses the time-delay height, the bottom of intermediate step 11 just contacts with Ejector Retainer Plate 8 surfaces, plastic product 3 ejected the height that exceeds stub bar 6 and separated with stub bar 6 this time, last stub bar push rod 5 just moves upward with product push rod 4, and plastic product 3 is ejected mould with the stub bar 6 that separates.
Claims (2)
1. a mould of plastics ejects time-delay structure, comprise thimble panel (7) and Ejector Retainer Plate (8), described thimble panel (7) and Ejector Retainer Plate (8) are fixed together, be fixed with product push rod (4) on the described thimble panel (7), described product push rod (4) one ends penetrate thimble panel (7), the other end is fixed on thimble panel (7) bottom, described thimble panel (7) is provided with stub bar push rod (5), be provided with step (11) in the middle of the described stub bar push rod (5), described thimble panel (7) and Ejector Retainer Plate (8) have the groove (12) of connection, it is characterized in that: described step (11) moves up and down in groove (12).
A kind of mould of plastics according to claim 1 eject time-delay structure, it is characterized in that: described product push rod (4) is T type shape.
