Abstract
The invention discloses a plastic injection molding machine and relates to the technical field of manufacture of injection molding machines. Two back connecting rod seats are cast at the upper portion and the lower portion of an adjustable template back face, one horizontal opening is respectively cast at the left position and the right position of the adjustable template back face, and two longitudinal horizontal through holes for installing guiding columns are respectively arranged on the outer end face of the horizontal opening and an adjustable template. Two front connecting rod seats integrated with a movable template are cast at the upper portion and the lower portion of a movable template back face. The plastic injection molding machine is characterized in that the adjustable template back face is cast with two horizontal openings replacing I-shaped plates in the prior art, the longitudinal horizontal through holes for installing the guiding columns are processed on the adjustable template and the horizontal openings in one time, accordingly the coaxiality of the guiding column installing holes is ensured, and originally and independently installed front connecting rod seats and back connecting rod seats are respectively and directly cast on the movable template and the adjustable template. The plastic injection molding machine is easy to install and has good interchangeability.
Description
Technical field
The present invention relates to injection machine manufacturing technology field, especially a kind of adjusting device of injection molding machine of plastic.
Background technology
As shown in Figure 1, this adjustment mould plate is connected with a crosshead by the piston rod of oil cylinder to the adjusting device of existing a kind of injection machine, and the lead connecting adjustment mould plate and I-shaped plate is through in the left and right hole of crosshead; Back link seat is arranged on adjustment mould plate, front rod seat is arranged on moving platen; One end of back link is arranged on back link seat, and the other end is connected with the rear end of front rod; The front end of front rod is arranged on front rod seat, and one end of middle connecting rod is connected with back link middle-end, the other end is connected with the upper and lower head of crosshead; During folding mould, the piston rod being arranged on the oil cylinder on adjustment mould plate stretches out promotion crosshead, and connecting rod during crosshead drives, middle connecting rod drivening rod assembly makes moving platen reciprocating.
There is following deficiency in this technical scheme: 1, adjusting device is made up of each several part part, and these parts are processed respectively, because adjusting device each several part parts size precision and position degree require high, add slightly deviation in man-hour, the part assembling difficulty of adjusting device, even part rejection will be caused; 2, adjustment mould plate and I-shaped plate are through two parts of identical pull bar, lead and set bolt is connected with between them, therebetween position of related features requires higher, because these two parts are separate machined, if add man-hour dimensional accuracy or position degree there is deviation, will make lead and set bolt that difficulty is installed during assembling, serious time even can affect the assembling of connecting rod ASSY.
Summary of the invention
The object of this invention is to provide a kind of injection molding machine of plastic, this injection molding machine of plastic can solve I-shaped plate and adjustment mould plate mismachining tolerance causes assembling difficult problem.
In order to solve the problem, the technical solution used in the present invention is:
This injection molding machine of plastic, comprise adjustment mould plate, moving platen, crosshead, back link, front rod, middle connecting rod, lead, the upper and lower at the described adjustment mould plate back side is respectively provided with a back link seat, described adjustment mould plate back side left and right sides is respectively provided with a transverse opening, be respectively arranged with left and right vertical equity through hole at the end face of described transverse opening and described adjustment mould plate, described lead is arranged in described left and right vertical equity through hole respectively; Described moving platen upper rear portion and bottom are respectively provided with a front rod seat.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, by originally separate back link seat, front rod seat respectively with adjustment mould plate, moving platen cast solid, clamped one time can complete the processing of all sizes and position degree, effectively ensure that the positional precision of front-rear linkage seat and moving platen, adjustment mould plate, decrease and process issuable position error respectively, also save the time of clamping workpiece simultaneously.
2, cancel oneself and have I-shaped plate part in technology, the substitute is and be respectively arranged with transverse opening at adjustment mould plate back side left and right sides; Add man-hour, the hole of installing lead can be processed by clamped one time, ensure that the axiality in the hole at the adjustment mould plate back side and the hole of transverse opening end face, make installation lead become quite easy.
3, whole adjusting device interchangeability is better.
Accompanying drawing explanation
Fig. 1 is that oneself has technology injection molding machine of plastic front view.
Fig. 2 injection molding machine of plastic front view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Injection molding machine of plastic shown in Fig. 2, comprises adjustment mould plate 1, moving platen 6, crosshead 2, back link 4,7, front rod 5,9, middle connecting rod 3,8; The upper rear portion of adjustment mould plate 1 and the centre position of bottom be respectively cast with one with adjustment mould plate 1 one back link seat, respectively casting out and adjustment mould plate 1 all-in-one-piece transverse opening at adjustment mould plate 1 back side left and right side, being respectively equipped with two in the outer face of transverse opening and adjustment mould plate 1 for installing the vertical equity through hole of lead; The upper rear portion of moving platen 6 and lower middle position respectively have one with moving platen 6 one front rod seat.
When injection molding machine of plastic is installed, the interstitial hole of crosshead 2 is connected and fixed with the piston rod of the mode transfer oil cylinder being arranged on adjustment mould plate 1 front, the borehole jack of the left and right head of crosshead 2 is contained in and is arranged on adjustment mould plate 1 with on two leads of transverse opening, one end of back link 4,7 is arranged in the back link seat of adjustment mould plate 1, the other end is connected with one end of front rod 5,9 respectively, and the other end of front rod 5,9 is arranged in the front rod seat of moving platen 6 respectively; One end of middle connecting rod 3,8 connects the middle part of back link 4,7 respectively, and the other end is connected with the upper and lower head of crosshead 2 respectively, and so far, injection molding machine of plastic installs.
Claims (1)
1. an injection molding machine of plastic, comprise adjustment mould plate, moving platen, crosshead, back link, front rod, middle connecting rod, lead, it is characterized in that: the upper and lower at the described adjustment mould plate back side be respectively cast with one with the back link seat of adjustment mould plate one, described adjustment mould plate back side left and right sides respectively casts out and adjustment mould plate all-in-one-piece transverse opening, be respectively arranged with left and right vertical equity through hole at the end face of described transverse opening and described adjustment mould plate, described lead is arranged in described left and right vertical equity through hole respectively; Described moving platen upper rear portion and bottom are respectively provided with a front rod seat.
