Abstract
The utility model provides a structure for preventing a thimble from going back, a hanging table is arranged at the end part of the thimble, a through hole is formed at the bottom, a positioning pin is arranged in the through hole by penetration, and the bottom end of the thimble is fixedly arranged on an ejector plate of a die. The thimble in the structure is clamped in a die core, the thimble can not go back, the product quality is improved, the structure is simple and the cost is low.
Description
Technical field
The utility model relates to the structure of thimble, specifically a kind of structure that prevents that thimble from falling back.
Background technology
The thimble that the ejecting mechanism of mould adopts is generally cylindrical and square, sees also Fig. 1, and this thimble 10 is cylindrical, and it is assemblied in can be up and down in the mould.When moulding, the end of thimble is subjected to penetrating pressure, can retreat, and causes the many glue in thimble position of product.As the thick thin or product of the meat of fruit product is Transparent Parts, and behind the many glue in thimble position, the surface of product can form the stress trace, directly influences the outward appearance and the quality of product.
The utility model content
Because above-mentioned problem, the thimble in the known technology is subjected to penetrating pressure, can retreat, and causes the many glue in thimble position, directly influences the outward appearance and the quality of product.The purpose of this utility model is to overcome the deficiencies in the prior art and defective, and a kind of structure that prevents that thimble from falling back is provided.
The utility model provides a kind of structure that prevents that thimble from falling back, thimble, and its end is provided with hanging platform, and the bottom offers through hole, and alignment pin is arranged in this through hole, this thimble bottom is fixedly arranged on the liftout plate of this mould.
More excellent, the side of the hanging platform of described thimble end is the inclined-plane.
More excellent, the gradient of described hanging platform side is 1 ° to 5 °.
Compared with prior art, the thimble in the utility model is sticked in the die, and thimble can't retreat, and has improved the quality of product, and it is simple in structure, and is with low cost.
Description of drawings
Fig. 1 is the thimble structure schematic diagram in the known technology.
Fig. 2 is a kind of overall schematic that prevents the structure that thimble falls back of the utility model.
Fig. 3 is the thimble end enlarged diagram of a-quadrant among Fig. 2.
Fig. 4 is a kind of assembling schematic diagram that prevents the structure that thimble falls back of the utility model.
The specific embodiment
For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 2 and Fig. 3, be respectively a kind of overall schematic of the structure that thimble falls back and enlarged diagram of thimble end of preventing of the utility model.Thimble 101 ends are provided with hanging platform 102, the side 105 of hanging platform 102 is the inclined-plane, the gradient on this inclined-plane is 1 ° to 5 °, the side 105 of this hanging platform 102 is made as the inclined-plane, make between hanging platform 102 and the die 106 (seeing also Fig. 4) and insert the broken inclined-plane breaking that becomes by zero degree, avoid thimble 101 to bump with die 106 (seeing also Fig. 4) in the return process, the side of these thimble 101 bottoms also offers through hole 103.
Please continue to consult Fig. 4, prevent the assembling schematic diagram of the structure that thimble falls back for the utility model is a kind of.One end of thimble 101 is arranged in the die 106, and the hanging platform 102 of this end engages with die 106, and the other end is arranged on liftout plate 107, and alignment pin 104 is arranged in the through hole 103 of this end side surface, and these thimble 101 bottoms are fixedly arranged on liftout plate 107.During moulding, the end face of thimble 101 has been subjected to injection pressure, but its hanging platform 102 engages with die 106, and this thimble 101 can't retreat.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
Claims (3)
1. a structure that prevents that thimble from falling back is characterized in that, comprising:
