Description
Technical Field
The utility model relates to an injection mold field, more specifically say, especially relate to a forming die is buried to screw tooth.
Background
An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used to mass produce parts of some complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification. When a plastic product is large, a plurality of inner thread holes are formed in the product, and if a thread withdrawing mechanism is designed for the mold, the mold is relatively complex and the injection molding stability is not good.
Disclosure of Invention
The invention aims to provide a thread embedding forming die, which is characterized in that threads are directly embedded into an injection molding cavity, so that the embedded threads are screwed out after a product is subjected to injection molding, the threads are directly formed, the stability is improved, and the working efficiency is improved.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a forming die is buried to thread, includes the mould body, and injection moulding chamber buries thread and magnet, the mould body includes public template and female template, and public template and female template contact surface center department are fixed to be equipped with public mold core and master model core, and the fixed injection moulding chamber of having seted up in public mold core and master model core contact surface center department, and the one end fixed mounting who closes on public mold core and female mold core on public template and the female template has set nut, and fixed blind hole has been seted up to injection moulding chamber both sides, and ejecting through-hole has been seted up to this fixed blind hole bottom center department, and the bottom adsorbs in this fixed blind hole has magnet, and this magnet up end slidable mounting has the thread of burying.
Further, the embedded screw thread comprises a screw thread forming block, a counter bore forming block and a fixed withdrawing block, the lower end face of the screw thread forming block is fixedly provided with the counter bore forming block, the lower end face of the counter bore forming block is fixedly provided with the fixed withdrawing block, and the center of the lower end face of the fixed withdrawing block is provided with an ejection positioning hole.
Furthermore, the magnet is columnar, and an exhaust through hole with the same diameter as the ejection through hole is formed in the central axis of the magnet.
Furthermore, a hexagonal surface for conveniently screwing out the embedded screw teeth is arranged on the outer ring surface of the fixed withdrawing block.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a directly bury the injection moulding intracavity with the screw thread, screw thread that messenger's product injection moulding back was twisted out and is buried makes screw thread direct forming, has increased stability, has promoted work efficiency.

fig. 2 is a front view of the embedded screw of the present invention.
Detailed Description
The present invention will be described in detail with reference to the attached drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the scope of the present invention more clearly defined.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a forming die is buried to thread, includes mould body 1, injection moulding chamber 2 buries thread 3 and magnet 4, mould body 1 includes male mold board 11 and female mold board 12, male mold board 11 and the fixed male mold core 13 and the female mold core 14 of being equipped with in female mold board 12 contact surface center department, male mold core 13 and the fixed injection moulding chamber 2 of having seted up in female mold core 14 contact surface center department, male mold board 11 and female mold board 12 go up close on the one end fixed mounting of male mold core 13 and female mold core 14 have set nut 6, fixed blind hole 21 has been seted up to the 2 both sides in injection moulding chamber that female mold core 14 was equipped with, ejecting through-hole 5 has been seted up in this fixed blind hole 21 bottom center department, this fixed blind hole 21 bottom adsorption of terminal has magnet 4, this magnet 4 up end slidable mounting has buries thread 3.
The embedded screw thread 3 comprises a screw thread forming block 31, a counter bore forming block 32 and a fixed withdrawing block 33, the lower end face of the screw thread forming block 31 is fixedly provided with the counter bore forming block 32, the lower end face of the counter bore forming block 32 is fixedly provided with the fixed withdrawing block 33, the center of the lower end face of the fixed withdrawing block 33 is provided with an ejection positioning hole 34, the magnet 4 is in a columnar shape, the central axis of the magnet 4 is provided with an exhaust through hole with the same diameter as the ejection through hole, and the outer annular surface of the fixed withdrawing block 33 is provided with a hexagonal surface 35 used for facilitating screwing out of the embedded screw thread.
In summary, the following steps: to big mould design screw thread withdrawing mechanism, the mould can be relatively more complicated, stability is also not good, and the screw thread buries the shaping fairly simplely, stability is fine, injection moulding efficiency is also higher, can also save the mould cost, only need increase a field work personnel, bury the direct injection moulding of mould benevolence the inside to the screw thread income, wait product injection moulding good, the product is taken out, twist out the screw thread income through the staff can, this utility model discloses obtain verifying many times in actual injection moulding, it is very effective.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, but all equivalent modifications or changes made by those skilled in the art according to the present invention should be included in the protection scope of the claims.
