Problems solved by technology
[0002] At present, the reset mechanism used in the mold industry is generally divided into: general reset mechanism and first reset mechanism, and the first reset mechanism is usually used: wedge bar triangular slider type first reset mechanism ball push tube type first reset mechanism wedge bar slider Swing rod type first reset mechanism, connecting rod type first reset mechanism, etc. Although the above-mentioned various first reset mechanisms can effectively achieve the first reset effect, the structure of the above-mentioned mechanisms is complicated and the processing cost is high.
[0003] The general reset mechanism usually uses a spring on the reset rod to reset, but the reset spring is easy to fail, especially when the selection of spring to preload ratio and compression ratio is unreasonable, the reset spring will quickly fatigue and fail. Therefore, The effect is not good

Embodiment Construction
[0013] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0014] see figure 1 , a reset mechanism for a plastic mold, comprising an upper template 1, a lower template 2, a reset rod 3, a push rod fixing plate 4 and a push rod bottom plate 5, the upper part of the reset rod 3 is set in the lower template 2; The lower part of the reset rod 3 is fixed on the push rod fixing plate 4, and the middle section of the reset rod 3 has a number of transverse through holes, which are distributed at intervals on the reset rod, corresponding to the through holes, and opened in the middle of the lower template 2. There is a horizontal positioning pin hole 11, the positioning pin hole 11 communicates with the installation hole of the reset rod, and a positioning pin 10 is slidably arranged in the positioning pin hole 11, which is used to fix the reset rod laterally and keep it at the required height Above; the push rod ...

The invention discloses a plastic mold reset mechanism which comprises an upper mold plate, a lower mold plate, a reset rod, a push rod fixing plate and a push rod bottom plate, wherein the upper partof the reset rod penetrates through the interior of the lower mold plate; the lower part of the reset rod is fixed on the push rod fixing plate; a plurality of transverse through holes are formed inthe middle section of the reset rod; the through holes are distributed in the reset rod at intervals; a transverse positioning pin hole is formed in the middle of the lower mold plate corresponding tothe through holes; the positioning pin hole is communicated with a mounting hole of the reset rod; a positioning pin hole is arranged in the positioning pin hole in a sliding manner and is used for transversely fixing the reset rod and retaining the reset rod at a needed height; the push rod fixing plate is fixedly connected with the push rod bottom plate; a flange is arranged on the lower part of the reset rod; a first groove is formed in the push rod fixing plate; a flange is clamped in the first groove; a second groove is formed just under the flange on the push rod bottom plate; and an elastic reset block is arranged in the second groove.
Description
technical field [0001] The invention relates to the field of plastic processing molds, in particular to a reset mechanism for plastic molds. Background technique [0002] At present, the reset mechanism used in the mold industry is generally divided into: general reset mechanism and first reset mechanism, and the first reset mechanism is usually used: wedge bar triangular slider type first reset mechanism ball push tube type first reset mechanism wedge bar slider Although the above-mentioned various first-reset mechanisms can effectively achieve the first-reset effect, such as the swing-rod type first-reset mechanism and the link-type first-reset mechanism, the structure of the above-mentioned mechanism is complicated and the processing cost is high. [0003] The general reset mechanism usually uses a spring on the reset rod to reset, but the reset spring is easy to fail, especially when the selection of spring to preload ratio and compression ratio is unreasonable, the rese...
