Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a mold for blank molding, so as to solve the problem that the injection liquid of the injection molding blank has a small amount of viscosity, and it is easy to produce fluid film sheets during the die-casting process of the mold, resulting in die-casting parting. The spacer of the surface and the inner template cavity is plugged, which causes the upper and lower diaphragms of the blank to be compressed, and the tooth grooves of the formed mold are narrowed up and down, and the deviation is large, which will cause seam dust to lead around the seamlessly spliced ​​finished mold. , leading to low saturation of the billet, and poor fine-tuning and slag removal efficiency of the mold, which generally reduces the processing pass rate of the overall mold

Embodiment 1

[0032] see Figure 1-Figure 6, the present invention provides a mold for forming blanks, the structure of which includes: a lock pin column tube 1, a cover mounted shaving rack mold groove 2, a parting surface groove block 3, a pillar plate 4, a cylinder rod 5, and a demoulding bottom cushion block 6. The base plate 7, the cover-mounted shaving frame mold groove 2 is nested on the top of the parting surface groove block 3 and is on the same horizontal plane, and the parting surface groove block 3 passes through the lock pin column tube 1 and the pillar The plates 4 are snapped together and are perpendicular to each other. The parting surface groove block 3 is mechanically connected with the demoulding bottom pad 6 through the cylinder rod 5 and is parallel to each other. The demoulding bottom pad 6 is closely attached to the base plate 7 and on the same horizontal plane, the cover-mounted shaving frame mold groove 2 is provided with an I-shaped long shaft rod 2A, a middle fram...

Embodiment 2

[0039] see Figure 1-Figure 6 , the present invention provides a mold for blank forming, other aspects are the same as in Example 1, the difference is:

[0040] see figure 2 , the pad support wheel frame seat 2F is composed of a pad support wheel disc 2F1, a shock-isolation spring clamp plate 2F2, and a square frame seat 2F3, and the cushion support wheel disc 2F1 is nested on the top of the shock-isolation spring clamp plate 2F2. The shock-isolation spring clip 2F2 is inserted and embedded on the top of the square frame seat 2F3 and is on the same vertical plane, and the shock-isolation spring clip 2F2 is pressed against by the support wheel 2F1 to form a load-bearing settlement force to ensure the edge of the frame cover Avoid wear and tear of the knife and improve the protective effect of the inner frame.

[0041] see Figure 6 , the shock-isolation spring clamping plate 2F2 is composed of a knuckle reinforcing rib 2F21, a lock pin clamping plate 2F22, a cross bar 2F23,...

Abstract

The invention discloses a blank forming mold which structurally comprises a lock pin column pipe, a covering shaving frame mold groove, a parting surface groove block, a supporting column plate block,an ejector sleeve rod, a demolding bottom cushion block and a base plate. The covering shaving frame mold groove is matched with the parting surface groove block, and a through frame cover groove islocked through the parting surface groove block; and an I-shaped long shaft rod is erected in the through frame cover groove to form a mud guard type scraping and shaving cleaning layering surface effect through a semicircular piece sliding seat, a fan paddle separation ladder plate can also be effectively swept, brushed and extended, anti-bonding stripping operation of annular surface alignment inserting and embedding is formed, bonded inner groove impurities can be effectively removed in advance through blank preparation and forming, then through deslagging and sliding lining, the effect ofstripping and cleaning to guarantee inner formwork accurate pressing covering is achieved, the whole mold can precisely form a machined part in a mold-casting mode, seam allowance deviation is avoided, and the machining integrity of the seamlessly-spliced mold is improved.

Description

technical field [0001] The invention relates to a mold for blank forming, which belongs to the field of molds. Background technique [0002] The injection mold cooperates with the processing and forming of the blank, and the runner needs to cooperate with the hydraulic cylinder to boost the injection liquid, so that the molded template can be wrapped up and down to form the inner fluid solidification, heat drying and condensation effect, and then demoulding output to obtain a complete high-precision genuine processing parts , so that the qualified rate of mold processing is generally improved. The shortcomings of the current technology to be optimized are: [0003] The injection molding liquid of the injection molding blank has a small amount of viscosity, which is easy to produce a fluid film sheet during the die-casting process of the mold, causing the die-casting parting surface and the septum of the inner template cavity to be plugged, resulting in the compression of the...
