In prior art, the trace of die gap 43 is regulated the main horizontal level that changes discharging opening outer lip 42 that relies on and is realized, utilize adjusting bolt 8 to regulate and change the relative level position of discharging opening outer lip 42 with respect to outer sleeve 3, and keep the horizontal level of discharging opening epipharynx 41, outer sleeve 3 constant simultaneously, as shown in Figure 1.But there is following shortcoming in this regulative mode: because above-mentioned adjustment process can cause the horizontal level of discharging opening outer lip 42 and outer sleeve 3, stagger, therefore can form prominent rank in the upper end of annular materials runner 5, the component level of should dashing forward is in the intersection of discharging opening outer lip 42 and outer sleeve 3, shown in B in Fig. 2.Like this, fused materials, when flowing through prominent rank, this B place, can be blocked, and even condenses in this place, prominent rank, affects the unobstructed of runner.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of blow moulding machine head die orifice slack adjuster is provided, and it can not make the annular materials runner produce prominent rank in the process of regulating die gap.
Its purpose can realize by following scheme: this blow moulding machine head die orifice slack adjuster comprises base, plug, outer sleeve, discharging opening epipharynx, discharging opening outer lip, outer sleeve is arranged on the base top, the discharging opening outer lip is arranged on the outer sleeve top, form annular die gap between discharging opening epipharynx and discharging opening outer lip, the discharging opening epipharynx is fixedly mounted on the plug upper end, plug is arranged in the middle of outer sleeve, form annular material runner between plug and outer sleeve, the material runner is communicated with die gap; It is characterized in that, the lower end of plug is fixedly connected with a regulating block, and the top of regulating block is hemisphere face shape and bottom is cylindrical; The base center upper portion is formed with the cavity that holds regulating block, the top of cavity is hemisphere face shape and bottom is cylindrical, the cylindrical lower portion diameter of cavity is greater than the cylindrical lower portion diameter of regulating block, and the sphere on cavity top coordinates with the sphere close contact on regulating block top; Also be provided with some adjusting bolts on base, each root adjusting bolt circumferentially is uniformly distributed along base, and each root adjusting bolt directly contacts or indirectly be connected to regulating block.
The installation direction of each root adjusting bolt is horizontal cross and is radial, and the end of each root adjusting bolt directly contacts the cylindrical lower portion of regulating block.
Regulating block also one is fixedly connected with a horizontal driver plate, and horizontal driver plate offers some screws; The installation direction of each root adjusting bolt is vertical, and each root adjusting bolt axial restraint and circumferentially be installed in rotation on base, every adjusting bolt correspondence is screwed into one of them screw of horizontal driver plate, and each root adjusting bolt is connected to regulating block indirectly by horizontal driver plate.
The utlity model has following advantage and effect:
1, regulating block is fixedly connected with the lower end of plug, and sphere-contact is formed at regulating block top and base top, therefore form one and can rotate the gimbal suspension of regulating to all directions trace, only need utilize adjusting bolt to promote regulating block, just can make plug rotate around this gimbal suspension trace, drive the position trace skew of discharging opening epipharynx, trace is regulated the relative position of discharging opening epipharynx and discharging opening outer lip thus, realizes that the trace of die gap is regulated.
2, in adjustment process, the material runner can not produce any prominent rank, avoids blocking flowing of fused materials, more avoids fused materials to put and condense in prominent component level, guarantees that the material runner is smooth and easy.
